Aluminum ammonium sulfate was used as a new catalyst for glyoxal to minimize the decrease of physical properties of durable
press cotton fabrics, and the optimum treatment conditions such as the concentration of glyoxal, molar ratio of catalyst to
glyoxal, curing temperature and time were investigated. The retention of tensile strength and the whiteness of fabrics treated
with glyoxal/aluminum ammonium sulfate was increased as much as to the degree of that obtained with glyoxal/aluminum sulfate
while wrinkle recovery angles were as good as those of the latter. Some additives such as DEG, polyurethane and softener were
used to improve the physical properties. When DEG or polyurethane was added to the glyoxal padding solution, wrinkle recovery
angle (WRA) significantly increased while tensile strength and whiteness were not influenced. DEG added to the glyoxal padding
solution increased the durability of DP finish. The softener added to the glyoxal padding solution increased the WRA of treated
fabrics while it decreased the tensile strength slightly. The whiteness of fabrics treated with glyoxal alone increased while
the WRA decreased slightly. 相似文献

In the conventional subjective method, wrinkled fabric specimens are visually compared with the standard replicas under a
specific light source in order to be evaluated and classified. In the present work, the rank ordering method is incipiently
applied for grading a wide range of wrinkled fabrics. The five standard replicas are orderly placed among the ranked specimens
and their grades are extracted. Results show that the specimens ranked by the ordering method are reliable and can be used
for grading of wrinkled fabric to overcome the problems associated with the standard method such as the limited grading range
and high and non uniform intervals between each pair of replicas. Conventional image processing methods used for grading fabric
wrinkle are also applied on images taken from the ranked specimens. Among the methods studied in the literature Radon transform,
wrinkle paths length and fractal dimension show a good correlation with the wrinkle grades derived from the rank ordering
method. 相似文献

Measuring and characterizing fabric wrinkling objectively and accurately is of vital importance because wrinkling behavior is one of the most important factors to determine visual aesthetic of fabrics and clothes. In this paper, a novel method for multidirectional fabric wrinkling measurement is presented. 12 fabrics with different fiber contents and weave structures are prepared and wrinkled by the new method. GLCM variables and standard deviation of wavelet decomposition coefficients are used to characterize fabric wrinkling. Results show that WRA (wrinkle recovery angle) does not have significant linear correlation with the GLCM variables (energy, entropy, contrast and correlation). The wavelet coefficient standard deviation at level 6 has the highest correlation with average WRA. The equations between average WRA and standard deviations can be used to predicate average WRA of a fabric conveniently, avoiding the time-consuming and tedious testing of WRA in each direction. 相似文献

Moisture management behavior is a vital factor in evaluating thermal and physiological comfort of functional textiles. This
research work studies functional 3 dimensional (3D) warp knitted spacer fabrics containing high-wicking materials characterized
by their profiled cross section. These spacer fabrics can be used for protective vest to absorb a user’s sweat, to reduce
the humidity and improve user’s thermal comfort. For this reason, different 3D warp knitted spacer fabrics were produced with
functional fiber yarns in the back layer of the fabric (close to the body) and polyester in the front and middle layers (outer
surface). Comfort properties such as air and water vapor permeability and wicking and other moisture management properties
(MMP) of different fabric samples were measured. It is demonstrated that by using profiled fibers such as Coolmax fiber, moisture
management properties of spacer fabrics can be improved, enabling them to be use as a snug-fitting shirt worn under protective
vests with improved comfort. 相似文献

High performance cellulosic fabrics are of increasing attention as a wearable fabric with special functions. The current report deals with preparation of multifunctional cotton fabrics by using simple and facile layer by layer technique. Firstly, silver nitrate was reacted with carboxymethyl cellulose to prepare Ag nanoparticles-carboxymethyl cellulose composite. Multi-layers of the so-obtained composite were applied on the cotton fabrics using pad-dry-cure method. Ag nanoparticles were deposited with mean size of 18.2 nm onto cotton fabrics which served as a cross linker between carboxymethyl cellulose macromolecules and cotton macromolecular blocks. Application of composite multilayers brought new properties for the finished cloths such like coloration, ultraviolet resistance, electrical resistance and biocidal action. The ultraviolet transmission radiation was significantly reduced to 7-10 % after applying ten composite layers. Valuable antibacterial textiles which are required in different medical purposes could be successfully produced, as excellent antibacterial activities were achieved by using the reported method. The developed process can be easily adapted to the existing textile machinery, making it industrially viable to produce fabric’s versatility. 相似文献

The thermal characteristics of hollow polyester fibers were compared with solid polyester fibers in order to study their processing behavior and performance characteristics. The effects of different processing and structural properties including fiber diameter, bulk density of layer, and surface pressure on layers of needle-punched nonwoven fabrics with hollow fibers on thermal resistance properties were also investigated. The results show that hollow fibers have a higher thermal resistance in comparison with solid ones. This is a consequence of air trapping inside the fibers, higher bulkiness, and higher surface area of hollow fibers. Furthermore, thermal resistance of microfibers is better than those of macrofibers in both hollow and solid fibers. The thermal resistance of nonwoven subjected to this study, have an inverted-U-shaped pattern versus the bulk density of the fabric. The results also showed that thermal resistance of needle-punched nonwoven fabrics can be affected by the range of heater temperature during the test, however considerably can be affected by fabric thickness as a main structural property of nonwoven fabrics. 相似文献

In this study, a facile method was developed to coat AgCl nanoparticles (NPs) onto knitted cotton fabrics. The AgCl NPs were characterized by ultraviolet absorption spectrum, X-ray diffraction (XRD) and dynamic laser light scattering (DLS). The AgCl NPs were coated onto cotton fabrics through a pad-dry-cure process with the assistance of 1,2,3,4- butanetetracarboxylic acid (BTCA). Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), ICP-OES analysis and energy-dispersive X-ray spectroscopy (EDX) confirmed that AgCl NPs were successfully coated onto cotton fabrics. The prepared cotton samples exhibited excellent antimicrobial activity against both Gram-positive S. aureus and Gram-negative K. pneumonia bacteria. Rat skin fibroblast cytotoxicity testing demonstrated the treated cotton fabrics to be non-toxic. The washing durability evaluation showed that the antimicrobial function of cotton fabrics was durable to washing. In addition, the wrinkle resistance of the coated cotton fabrics was improved and there was no obvious change in whiteness. 相似文献

In this study, an analysis on the breaking elongation mechanism of the polyester/viscose blended open-end rotor spun yarns
has been carried out. In addition, a back propagation multi layer perceptron (MLP) network and a mixture process crossed regression
model with two mixture components (polyester and viscose blend ratios) and two process variables (yarn count and rotor speed)
are developed to predict the breaking elongation of polyester/viscose blended open-end rotor spun yarns. Seven different blend
ratios of polyester/viscose slivers are produced and these slivers are manufactured with four different rotor speed and four
different yarn counts in rotor spinning machine. In conclusion, ANN and statistical model both have given satisfactory predictions;
however, the predictions of ANN gave relatively more reliable results than those of statistical models. Since the prediction
capacity of statistical models is also obtained as satisfactory, it can also be used for breaking elongation (%) prediction
of yarns because of its simplicity and non-complex structure. In addition, it is also found in this study that yarn count,
rotor speed and breaking elongation of polyester-viscose fibers and the blend ratios of these fibers in the yarn have major
effects on yarn breaking elongation. 相似文献

The aim of this study is to analyze and determine the off-axis tensile properties of air-entangled textured polyester fabrics
based on unit cell interlacing frequency. For this purpose, continuous filament polyester air-entangled textured yarn was
used to produce plain, ribs and satin woven fabrics. The fabrics were cut from the warp direction (0°) to weft direction (90°)
at every 15° increment, and tensile tests were applied to those of the off-axis samples. The strength and elongation results
were introduced to the statistical model developed, and regression analyses were carried out. Hence, the effects of off-axis
loading and interlacement on the directional tensile properties of the fabric were investigated. The regression model showed
that off-axis loading influences fabric tensile strength. On the other hand, interlacement frequency is the most important
factor for fabric tensile elongation. The results from the regression model were compared with the measured values. This study
confirmed that the method used in this study as can be a viable and reliable tool. Future research will concentrate on multiaxially
directional fabric and the probability that it will result in homogeneous in-plane fabric properties. 相似文献

In order to impart barrier properties against water and microorganisms on breathable three dimensional spacer fabrics as medical
or technical textiles, fabric samples were treated with two water repellent agents and a quaternary ammonium salt namely cetyltrimethylammonium
bromide (CTAB), using pad-dry-cure method. Two different water repellent agents based on hydrocarbon and acrylic copolymer
were used. The water repellent property of samples was tested by Bundesmann and contact angle tests. Antimicrobial activity
of samples was analyzed quantitatively according to AATCC 100. Simultaneous finishing of samples was done with 3 % CTAB and
4 % fluoroalkyl acrylic copolymer. To study the effect of various treatments on comfort related properties, air and water
vapor permeability, water repellency and compression were measured. The results showed that the antimicrobial and water repellent
spacer fabrics can be achieved applying selected material without significant changes on their comfort properties. Also a
regression model was presented to predict the water vapour permeability of knitted spacer fabrics based on course density
(CPC) changing. 相似文献

Electromagnetic shielding has a very emerging role in the textile applications. Screen-printing is a well-known, easy and cost effective process for textile printing. In this study, carbon black and graphite particles were used to impart electromagnetic shielding property to polyester fabric by screen printing technique. To this aim, printing pastes containing carbon materials were prepared with different binder concentrations. The electrical resistance, surface morphology, color coordinates and washing fastness properties of screen printed polyester fabrics were investigated. The washing durability of electromagnetic shielding effectiveness of carbon based printed fabrics as a function of binder concentration have also been studied. Electromagnetic shielding effectiveness was evaluated in the frequency ranges between 15-3000 MHz. The results showed that the electromagnetic shielding properties of fabric were affected by increased binder concentration. The most durable electromagnetic shielding effectiveness after washing process was obtained at highest binder concentration. The surface morphologies and color difference values of printed fabrics after washing process also provided a positive contribution. 相似文献

Plasma treatment is a kind of environmentally friendly surface modification technology, which has been widely used to modify
various materials in many industries. Plasma treatment improves the fiber-matrix adhesion largely by roughening the surface
of fibers to increase mechanical interlocking between the fiber and the matrix. For this aim, the effect of atmospheric air
plasma treatment on jute fabrics has been discussed in this study. The plasma treatment has been employed at different powers
and time intervals. The effects of plasma treatment on fiber properties were revealed by wickability, surface roughness, fiber
tensile test and pull-out tests. The effect of plasma treatment on functional groups of jute fibers was observed by attenuated
total reflectance fourier transform infrared spectroscopy (ATR-FTIR). Scanning electron microscopy (SEM) images showed the
etching effect of plasma treatment on the surface. It can be concluded that plasma treatment is an effective method to improve
the surface and mechanical properties of jute fabrics to be used for composite materials. 相似文献

Denim, a twilled cotton fabric, was used to enhance the mechanical and thermal properties of poly(lactic acid) (PLA). The
denim fabric reinforced composites with different numbers of denim layers were fabricated by using a hand layup method. The
impact, tensile, and dynamic mechanical properties of the composites were observed with increasing denim layers to examine
the reinforcing effect of denim fabrics. Numerical analysis was carried out to model the elastic modulus of the composite
by using a commercial software. Three-dimensional geometry of the denim fabric reinforced PLA composite was generated through
a CAD program, and the elastic modulus was calculated by applying uniform deformation on one surface. The impact strength,
tensile strength, and thermal properties of the composites were improved by piling denim fabrics. The denim fabric reinforced
composites exhibited outstanding impact strength due to the retarded crack propagation as well as large energy dissipation.
The 3 layer denim reinforced composite showed best results among all specimens, and its impact strength, tensile strength,
and tensile modulus were measured to be 82 J/m, 75.76 MPa, and 4.65 GPa, respectively. The PLA/denim composites have good
mechanical properties and can substitute traditional composites such as glass fiber or carbon fiber reinforced composites. 相似文献

This study was done to propose color conditions and fabrics that satisfy the particular sensibilities of consumers and producers through an analysis of color sensibility factors for an environmentally-friendly material, i.e., naturally colored organic cotton (NaCOC) fabrics. Toward that end, the colorimetric properties of eight NaCOC fabrics were measured, and the fabrics?? subjective color sensibilities were evaluated. In addition, based on the relationship between the colorimetric properties and subjective color sensibilities, the prediction models for color sensibilities of NaCOC fabrics were developed. According to the established models, hard-soft, cool-warm, deep-pale, vague-distinct, plain-showy, and subdued-vivid sensibilities can be predicted by some variables of colorimetric properties such as L*, a*, C*, and h. As another ultimate goal of this study, suitable NaCOC fabrics to evoke certain sensibilities were proposed by multidimensional scaling method. The proposed fabrics and color sensibility factors are believed to offer an important guideline for those who design clothing products made of NaCOC. 相似文献

The aim of this study is to develop new pattern denim fabrics and characterize the mechanical properties of these fabrics after abrasion load. Furthermore, tensile and tear strengths of these fabrics have been analysed by using the Artificial Neural Network (ANN) and statistical model. All denim fabrics were first abraded and subsequently tensile and tearing tests were applied to the abraided fabrics seperately. Actual data generated from the tests were analyzed by ANN and regression model. The regression model has shown that tensile strength properties of the abraded large structural pattern denim fabrics are generally low compared to that of the small structural pattern and traditional denim fabrics. On the other hand, when the abrasion cycles are increased tensile properties of all denim fabrics are generally decreased. Tearing strength of weft and warp in the abraded large structural pattern denim fabrics are between small structural pattern and traditional denim fabric. On the other hand, when the abrasion cycles are increased tearing strength properties in the weft and warp for all denim fabrics are generally decreased. The results from ANN and regression models were also compared with the measured values. It is concluded that almost all values from ANN are accurately predicted compared with those of the regression model. Therefore, we suggest that both methods can be used in this study as viable and reliable tools. 相似文献

Waterproof breathable layered fabrics allow water vapor passing through, but resist liquid water to pass. This ability of the fabrics to protect rain and snow water while allowing sweat vapor to evaporate from inside to outside atmosphere, leads them to be used as outdoor sportswear or protective clothing. The big challenge of enhanced hydrostatic resistance of these fabrics with proper breathability and thermal comfort has widened the research scope. This study presents an experimental investigation on hydrostatic resistance and thermal behavior of layered waterproof breathable fabrics. Six different types of hydrophobic and hydrophilic membrane laminated layered fabrics were evaluated by varying different fabric parameters in the experiment. Hydrostatic resistance and water vapor permeability of the laminated fabrics were measured by SDL ATLAS Hydrostatic Head Tester and PERMETEST respectively. Thermal properties were evaluated by ALAMBETA instrument. Moreover, FX-3300 air permeability tester was used to measure air permeability which represents the porosity of the fabrics and computer based See System software was used for water contact angle measurement on the outer fabric surface in order to determine the hydrophobic and hydrophilic properties. This experiment clearly discusses the influence of different fabric characteristics and parameters on hydrostatic resistance and thermal properties of the breathable laminated fabrics. The results show that fabric material composition, density, thickness, and hydrophobic and hydrophilic membranes have significant effects on hydrostatic resistance, breathability and thermal properties of different laminated fabrics. 相似文献

The optimum conditions for durable press treatment of cotton fabrics using glyoxal as a nonformaldehyde crosslinking agent
were investigated. Crosslinking reaction was conducted in the presence of different catalysts such as aluminum sulfate, magnesium
chloride, or magnesium chloride-citric acid mixture at various mole ratios of catalyst to glyoxal. Aluminum sulfate was proven
the most effective one among those used. Glycol addition into a glyoxal padding bath increased the wrinkle recovery angle(WRA)
and whiteness of treated fabrics. The optimum mole ratio of glycol to glyoxal was 1:1. Diethylene glycol addition produced
better overall performance to the glyoxal-crosslinked fabric compared to ethylene glycol addition. 相似文献

In this study, an artificial neural network (ANN) and a statistical model are developed to predict the unevenness of polyester/viscose
blended open-end rotor spun yarns. Seven different blend ratios of polyester/viscose slivers are produced and these slivers
are manufactured with four different rotor speed and four different yarn counts in rotor spinning machine. A back propagation
multi layer perceptron (MLP) network and a mixture process crossed regression model (simplex lattice design) with two mixture
components (polyester and viscose blend ratios) and two process variables (yarn count and rotor speed) are developed to predict
the unevenness of polyester/viscose blended open-end rotor spun yarns. Both ANN and simplex lattice design have given satisfactory
predictions, however, the predictions of statistical models gave more reliable results than ANN. 相似文献

Chitosan is a natural nontoxic biopolymer used widely in various fields due to the antimicrobial activities. In this study,
the properties of polyester fabrics grafted with chitosan oligomers/polymers after being activated by atmospheric pressure
plasmas were evaluated. The antibacterial effect was most evident when the surface of fabrics was activated by atmospheric
pressure plasma for 60 to 120 seconds and grafted with chitosan oligomers. The modified fabrics also exhibited good biocompatibility.
This process can be applied to a large area and used to produce antibacterial polymer fibers. 相似文献

The perpendicular-laid nonwoven fabrics may show high loft performance because of the structure composition, which has much
fiber oriented in the thickness direction. The ability to maintain the thickness after the cyclic loading is a basic requirement
of good high lofts. When the perpendicular-laid nonwoven fabrics are put to practical use as a cushion material, the compressional
properties of the cyclic loading should be significant. In this study, a compressional fatigue system has been developed and
evaluated with two kinds of perpendicular-laid nonwoven fabrics with different manufacturing processes. The system equation
developed provides a stress profile that can be used for analyzing the practical compressional fatigue. The fiber structure
of the perpendicular-laid nonwoven fabrics was investigated by using the orientation distribution function (ODF). 相似文献
