The effect of blend percentage on comfort and handle related properties of fabrics made from polyester/viscose blended air-jet
textured yarn weft were studied and the results were compared with fabrics made from polyester/viscose ring-spun yarn wefts
of similar linear densities. It is observed that with increase in polyester content in the blend, the air permeability and
water vapour permeability reduces whereas thermal resistance, transverse wicking and shear rigidity increases both in ring-spun
yarn and textured yarn fabrics and bending rigidity increases in textured yarn fabrics. Textured yarn fabrics exhibit lower
air permeability and extensibility, higher thermal resistance, relative water vapour permeability, transverse wicking values
and bending rigidity as compared to the ring-spun yarn fabrics. 相似文献

The effects of fabric balance and fabric cover on surface roughness values of textured polyester woven fabrics with different constructional parameters were investigated. The warp yarn properties (type, count and warp density) were kept constant while the effect of variation in weft yarn density and weave pattern were studied. Measurements were conducted on pre-treated white fabric samples and the results assessed in relation to their constructional properties. A general overview of the results showed that surface roughness values of polyester fabrics affected by fabric balance and fabric cover and the effects were related to fabric thickness, yarn densities, yarn crimp, positioning of yarns in fabric structure. A change in weave pattern from sateen to plain increased the fabric balance and fabric cover, but decreased the surface roughness. Similarly, an increase in weft density increased the fabric balance and fabric cover, but decreased surface roughness. In order to produce fabrics with smooth surface properties yarn density should be increased, yarn float lengths decreased, cover of fabrics increased and fabric balance improved. 相似文献

The effects of some yarn properties (i.e. type, count, twist level, ply number, unevenness and crimp) and fabric constructional properties (i.e. cover, thickness and balance) on surface roughness values of cotton woven fabrics were investigated. A general overview of the results showed that surface roughness values of fabrics were affected from yarn and fabric properties and the effects were related to fabric balance, fabric cover (not cover factor), fabric thickness and crimp values of yarns in fabric structures. Surface roughness values of fabrics decreased as yarn fineness and yarn twist levels increased but as yarn ply number decreased. Also, surface roughness values gradually decreased from open-end yarn constituting fabrics to combed yarn constituting fabrics. Results showed that different properties of yarns caused changes in yarn crimps in fabric structure and also governed the changes in fabric balance, as well as changes in roughness of fabric surfaces. The changing properties of yarns and impact of these properties on fabric construction affected the formation of cotton fabric surfaces from smooth to coarse. 相似文献

The effects of yarn number and liquid ammonia (L/A) treatment on the physical properties of woven fabrics prepared with pure hemp spun yarns were investigated. As a result of L/A treatment, the crystal structure of hemp fiber was changed from cellulose I to the mixtures of cellulose III and cellulose I and its crystallinity was slightly decreased by 13 %. The crease recovery of hemp fabric treated with L/A was improved upto 78 %. The washing shrinkage of hemp fabric treated with L/A decreased significantly to less than 0.4 %, while the washing shrinkage of hemp fabric prepared with the fined yarn was superior to that of hemp fabric prepared with the coarsed yarn. Especially, the wicking speed and drying ratio of hemp fabrics treated with L/A were higher than those of the untreated as yarn number increased. However, it was found that there is no significant effect on the UV protection of the L/A treated hemp fabrics. 相似文献

This paper focuses on the assessment of the relation among constructional properties, fractional reflectances and cover factors
of fabrics woven from polyester yarns. A novel equation for the calculation of the relation between fractional reflectance
and fabric cover factor was proposed and the usage of the equation was assessed by reflectance measurements. 48 polyester
fabrics having different constructional parameters were used and the fabrics differed from each other by their cover factors.
The warp yarn type and count, warp density and warp yarn twist were the same but weft yarn count, weft yarn fiber count and
weft density were different for the fabrics in the experimental sub-groups. The reflectance measurements were conducted on
the pretreated but undyed fabric samples as well as on the individual yarn systems of the same fabrics. Fabrics with the same
cover factors exhibited different fractional reflectances. Reflectances were found to be dependent on the cover factor as
well as on yarn fiber fineness, yarn count, yarn density and fabric weave. The changes in crimp of the yarns according to
different construction parameters also governed the changes in fractional reflectances of fabric surfaces. The proposed equation
was tested according to different fabric construction parameters and it was concluded that fiber fineness and weave pattern
were among the most important parameters which govern the total light reflectances from the fabric surfaces, although they
are not incorporated in the calculation of the fabric cover factors. The proposed equation was used to explain the effects
of these components on the reflectance behavior of the fabric surfaces and on fabric cover. 相似文献

Peirce’s fabric model has been widely used to predict the structural behavior of various plain woven fabrics. The structure
of plain woven fabric can be defined in terms of the warp yarn number, weft yarn number, warp fabric density, weft fabric
density, warp crimp, and weft crimp. The warp and weft yarn diameters are calculated from the warp and weft yarn numbers,
and the effective coefficient of the yarn diameter is defined by using this model. We have investigated structural properties,
such as the effective coefficient of the yarn diameter, yarn crimp, and fabric thickness for two different fabrics in which
the constituent yarns are assumed to be either incompressible or compressible. This model is also applied to various plain
fabrics woven from cotton, rayon, wool, linen, nylon, acetate, polyester, and silk yarns. 相似文献

Comfort is one of the most important aspects of clothing. Thermal comfort is related to fabric’s ability to maintain skin temperature and allow transfer of perspiration produced from the body. Properties like thermal resistance, air permeability, water vapor permeability, and liquid water permeability are suggested as critical for thermal comfort of clothed body. In this study the fabrics developed from the EliTe compact yarns are compared with the fabrics made from normal yarns. The thickness of the fabrics made from EliTe® compact yarns is also slightly less than the fabrics made from normal yarns. Fabrics made from EliTe® compact yarns have shown greater air permeability as compared to the fabrics made from normal yarns. It is observed that, thermal resistivity values of the fabrics developed from EliTe® compact yarns are lower than the fabrics made from normal yarns indicating they are cooler fabrics compared to normal fabrics. Fabrics developed from the EliTe® compact yarns have shown slightly higher values of MVTR (moisture vapor transmission rate) as compared to the fabrics made from the normal yarns. The wicking characteristic of fabrics developed from EliTe® compact yarns was slightly higher than the fabrics developed from normal yarns. 相似文献

Composite woven fabric satisfies what people require. Bamboo charcoal (BC) has been identified as a multifunctional material
that has far-infrared ray, anions, deodorization and etc. BC fibers and yarns were made of bamboo charcoal powders and have
further become a pervasive materials used in textile industry. In this study, cotton yarns, stainless steel/cotton (SS/C)
complex yarn, bamboo charcoal/cotton (BC/C) complex yarns were woven into the plain, twill and Dobby composite woven fabrics.
The warp yarn was composed of cotton yarns, and the weft yarn was made up of BC/C and SS/C complex yarns with a picking ratio
of 1:1 and 3:1. Thermoplastic polyurethanes (TPU) film was then attached to the composite woven fabrics, forming the BC/SS/TPU
composite woven fabrics. Tests of electromagnetic shielding effectiveness (EMSE), far-infrared emissivity, anions, water resistance,
and water vapor permeability measured the single-layer, two-layer and four-layer composite woven fabrics, obtaining a far-infrared
emissivity of 0.95 by 39.8 counts per minute, an anion count of 149 amount/cc, an EMSE of −11.87 dB under frequency of 900
MHz, a surface resistivity of 8×10−6 Ω/square, a water resistance of −8219 mmH2O, and water vapor permeability of 989 g/m2·h and 319 g/m2·24 h in accordance with JIS L 1099 A1 and ASTM E96 BW. 相似文献

The woven fabric graphics designed with available computer aided design (CAD) systems using different colored warp and weft
yarns look quite different from the appearance of their actual fabrics. To enhance the visual effects of designed woven fabric
graphics, this paper reports a modified CAD woven fabric system, which allows users to design a fabric using parameters including
fabric weaves, yarn number, yarn material, fabric count, crimp shape of interwoven yarns, and illumination. This enhanced
system can design both yarns and fabrics, and consider the transitional color effect around interweaving points of warp and
weft yarns. Its simulation image quality of woven fabrics has been greatly improved, and several textile mills and universities
are currently using this woven fabric design system. 相似文献

In this study, electromagnetic shielding characteristics of woven fabrics made of hybrid yarns are investigated. For this
purpose, initially the hybrid yarns containing stainless steel wire are produced with hollow spindle covering technique, and
then eight different fabric samples are produced using these hybrid yarns. Electromagnetic shielding values of fabric samples
are determined by a test set up based on enclosure measurement technique. Measurements are made in the frequency range of
30 MHz-9.93 GHz. Test results show that woven fabric samples investigated in this study have 25–65 dB electromagnetic shielding
effectiveness for incident frequency. It was also shown that the direction, density and settlement type of conductive hybrid
yarn in fabric structure are important parameters affecting electromagnetic shielding characteristics of woven fabrics. 相似文献

This paper focuses on the reflectance prediction of colored (unicolored) fabrics considering relationship between fractional reflectance values and cover factors of fabrics woven from polyester yarns. A novel equation for the calculation of relation between fractional reflectance and cover factor was proposed and usage of the equation was assessed by reflectance measurements. 48 dyed polyester fabrics having different constructional parameters were used and fabrics differed from each other by their cover factors. Warp yarn type and count, warp density and warp yarn twist were the same but weft yarn count, weft yarn fiber count and weft density were different for the fabrics in experimental sub-groups. The reflectance measurements were conducted on the dyed fabric samples as well as on the individual yarn systems (warp and weft) of the same fabrics. The proposed equation was tested according to different fabric constructional parameters and reasonable results with the experimental data were obtained. The possibilities of general use of derived mathematical relations between theoretical and measured reflectance values were researched. The relation obtained was used to explain the effects of different constructional parameters on reflectance behavior of fabric surfaces. 相似文献

The tensile properties of air-entangled textured polyester single and multiple yarn ends before and after weaving were analyzed.
The effects of weaving process considering fabric unit cell interlacement and number of yarn ends were evaluated by regression
model. For this purpose, plain, ribs and satin woven fabrics were produced. The yarns were raveled from fabrics, and the tensile
tests were applied to these yarns. The developed regression model showed that the number of interlacement and crimp ratio
on the warp and weft yarns influence their tensile strength. Tensile strength of raveled yarns decreased compared to that
of the bobbin yarn due to the effect of weaving process. This property degradation on the ravel yarns considered process degradation.
Generally, when the number of warp and weft yarn ends increases, the warp and weft yarn tensile strengths for each fabric
type decrease, whereas the warp and weft yarn tensile elongations slightly increase. The results from regression model were
compared with the measured values. This study confirmed that the method in the study can be a viable and reliable tool. The
research finding could be useful those who work on preform fabrication. 相似文献

Tearing strength is one of the most important and critical properties related to durable press finished cotton woven fabric. In the past, modelling of tearing strength of cotton woven fabrics was based on untreated cotton woven fabric but not in durable pressed finished fabric. In this paper, a mathematical model was established to demonstrate the tearing strength mechanism of durable press finished cotton woven fabrics by dimensional analysis based on yarn diameter, cover factor, Young’s modulus and fabric elongation. The proposed model agreed well with experimental results and the proposed model can be used for optimizing durable press finishing process of cotton woven fabric. 相似文献

With the increasing demand of fabrics for special usage areas, more complex woven structures are designed and from the structural
point of view, especially the parameters which affect the comfort properties become more important. This paper reports the
effect of structural parameters of double layered woven fabrics, such as number of interlacing picks, period of interlacing
and number of weft skips on the basic comfort properties of the fabrics (thickness, air permeability and wicking properties)
produced according to Taguchi orthogonal array design. The investigated parameters were determined before and after finishing
treatment. According to the results, it is found that period of interlacing has an important effect on the thickness and air
permeability of both untreated and treated fabrics whereas in terms of drying coefficient, the effect of the investigated
parameters is not statistically important. 相似文献

Delamination is the most common failure mode in laminated composites, due to the reduced strength in the through-the-thickness direction. This paper describes the development of core-and-effect textured glass yarns for improving the bonding strength of laminated glass woven fabric composites. Air-jet texturing introduces bulk and loops in the yarn which provides more contact surface between the fibers and the resin. However, the yarn tenacity decreases after texturing because of the reduced alignment of the filaments. The effects of texturing air pressure, yarn overfeed ratio, yarn linear density and core-sheath ratio were studied in this paper. The tenacity of glass yarns decreased significantly after the texturing process. The reduction was smaller for yarns with a higher core linear density. The effects of texturing air pressure on the tenacity were found to be insignificant. 相似文献

The aim of this study was to model the air permeability of polyester cotton blended woven fabrics. Fabrics of varying construction parameters i.e. yarn linear densities and thread densities were selected and tested for air permeability, fabric areal density and fabric thickness. A total of 135 different fabric constructions were tested among which 117 were allocated for development of prediction model while the remaining were utilized for its validation. Four variables were selected as input parameters on basis of statistical analysis i.e. warp yarn linear density, weft yarn linear density, ends per 25 mm and picks per 25 mm. Response surface regression was applied on the collected data set in order to develop the prediction model of the selected variables. The model showed satisfactory predictability when applied on unseen data and yielded an absolute average error of 5.1 %. The developed model can be effectively used for prediction of air permeability of the woven fabrics. 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

This study examined the flame retardant, anti-static, and wear comfort properties of woven fabrics from two types of yarns composed of modacrylic, FR-rayon, cotton, and anti-static PET fibers. The FR-rayon-blended modacrylic fabric mixed with anti-static PET fibers exhibited better flame-retardant and anti-static properties than those of the cotton-blended modacrylic fabric. In addition, the absorption and drying properties of the FR-rayon-blended modacrylic fabric were superior to those of the cotton-blended modacrylic fabric. The thermal conductivity of the FR-rayon-blended fabric was lower than that of the cotton-blended one, whereas the water vapor permeability was slightly higher than that of the cotton-blended one. These wear comfort properties of the FR-rayon-blended fabric were attributed to the micro-pores and longer fiber length of the FR-rayon fibers, as well as their yarn and fabric structural parameters. This study suggests that FR-rayon-blended modacrylic fabric has better flame-retardant and anti-static properties in both twill and rip weaves with good warmth keepability, and higher water and vapor transmission properties than cotton-blended one. In addition, the FR-rayon-blended modacrylic clothing exhibited a better wear comfort feel than the cotton-blended one due to the lower microclimate humidity. This means that FR-rayon-blended modacrylic fabric makes it more comfortable to wear than cotton-blended one. 相似文献

There are several studies related with knitted fabric containing elastomeric yarn. These studies have been carried out only
on fabrics containing naked elastomeric yarn, i.e., without intermingling. And most of them have focused on dimensional and
extension-recovery properties of the fabric. Of course, intermingling yarn parameters such as number of knots and draw-ratio
will affect the properties and performance of the fabrics. This paper presents a study about the effect of draw-ratio and
number of knots, which are important parameters in intermingled nylon-elastomeric yarns, on the physical and comfort properties
of hosiery knit products. To see the relationship and significance, bivariate correlation analysis and analysis of variance
have been carried out. It has been seen that increase of draw ratio and number of knots lead to an increase in dimensional
change, stitch density, fabric weight, and lead to a decrease in fabric spirality, abrasion, fabric wicking (wickability in
course direction is less than that of wale direction). Fabric thickness increases with an increase in draw ratio and a decrease
in number of knots. The number of knots and the draw-ratio do not affect the fabric drying rate. However, an increase in the
draw ratio and the number of knots result in an increase in initial water content before beginning the drying process. But,
an increase in initial water content is not so high as to affect the drying rate. 相似文献

Cellulase is useful for bio-polishing cotton fabrics which enhances their aesthetic performance instead of stonewashing process. Torque-free ring spun process is a widely used technique to produce newly low-twist and balanced torque yarns with soft hand. In this paper, denim fabrics woven with torque-free ring spun yarn and conventional ring spun yarn respectively were treated with cellulase under the same condition and their fabric handle, expressed as low stress mechanical properties, such as tensile strength, bending, shearing, compression and surface performance were investigated by Kawabata Evaluation System for Fabric (KES-F). After cellulase treatment, both denim fabrics revealed better flexibility, elasticity recovery, raised shearing stiffness, fluffier and improved smoothness. While torque-free ring spun yarn made denim fabric showed a better fabric handle than conventional ring spun yarn made denim fabric. 相似文献
