棉花是六十七团的支柱产业,实现棉花机械化采摘是提高劳动生产率、解决劳动力不足、降低采摘成本、走现代化农业的必由之路。为此,该团从2008年开始试验机采棉的种植,2009、2010年扩大种植面积1000hm^2。但是,随着机采棉面积的不断扩大,机采棉采净率的高低成了首要解决的问题．为总结机采棉经验．提高采摘质量．现对机采棉采摘时影响采净率的原因以及解决办法分析探讨如下。 相似文献

基于AFIS测试的机采棉和手采棉纤维品质分析 总被引：1，自引：0，他引：1
为更全面了解机采棉和手采棉纤维品质差异,简单介绍了Advance fiber information system(以下简称AFIS)的测试原理以及测试指标,并利用AFIS PRO2单纤维测试仪对机采棉和手采棉进行测试,详细分析了机采棉和手采棉在棉结、适纺纱线支数及纤维长度方面的差异。结果表明:机采棉棉结性能跟手采棉相似,长度略短于手采棉,总体上机采棉的纤维品质略差于手采棉,但差别不显著,为机采棉的推广提供依据,同时为纺织企业配棉、用棉提供参考。 相似文献

测试分析了2019年度阿克苏地区抽检的130批次（机采棉57批次，手摘棉73批次）细绒棉的棉结和短纤维率，并将手摘棉和机采棉进行分类比较。手摘棉与机采棉平均每克纤维棉结数分别为194、240，平均每克籽屑棉结数分别为39、46，平均每克棉结数分别为234、286；12.7 mm短纤维率主要分布在8%～12%，手摘棉在该范围的占比为61%，机采棉仅为36.8%；16 mm短纤维率主要分布在12%～18%，手摘棉在该范围的占比为76.7%，机采棉仅为59.7%。可知，2019年度阿克苏地区手摘棉棉结数和短纤维率均优于机采棉。 相似文献

机采棉化学脱叶施药技术发展现状及对策——基于新疆兵团184团的调研 总被引：1，自引：1，他引：0
<正>自1996年在全国率先引进采棉机开始试采和推广,经过十余年的发展,新疆兵团机采棉取得了长足发展。截至2013年,兵团棉花机采面积达到39万hm~2,占兵团棉花播种面积的66.2%。在扩大机采棉种植面积的同时,新疆兵团还积极探索与机采相配套的栽培模式,确保棉花的高采净率和机采棉质量。但在机采棉快速推进过程中也遇到了一些问题,如棉花品种品质差、脱叶效果不理想、收获的子棉含水率高、加工销售困难多等。为了更好地发挥兵团机采棉示范团场在棉花产业发展中的 相似文献

In this research work, behavior of flexural stiffness of core spun cotton spandex single jersey, 1x1 rib and interlock fabrics was studied under relaxation and machine washing treatments. Results are compared with similar fabrics made from 100 % cotton. Fabric weight density increased with the progression of treatments and it is proportionate to the fabric tightness factor (stitch length?1). Even though both types of fabrics had same machine set stitch lengths, cotton/spandex fabrics have shown the higher fabric weight densities than that of 100 % cotton fabrics. Although 1x1 rib and single jersey fabrics knitted with the same machine set stitch lengths, rib fabrics have given higher fabric weight densities than single jersey fabrics. Among the three knitted structures, interlock fabrics with higher machine set stitch lengths gave the higher fabric weights. Fabric stiffness and flexural rigidity have given higher values under the progression of treatments and it was found that higher values of stiffness have given by cotton/spandex knitted fabrics compared to their cotton fabrics. Fabric stiffness and flexural rigidity in wale direction were higher than that in course direction, but it is only observed in single jersey fabrics. However, 1x1 rib and interlock fabrics have shown an opposite behavior. It was also observed a positive correlation between TF (i.e.: stitch length?1) and bending length/flexural rigidity in both fabric types. Lower flexural rigidities reported with single jersey structures and highest values gave with interlock structures of cotton/spandex and cotton fabrics. 相似文献

In this research work, air permeability variations of core spun cotton/spandex single jersey and 1×1 rib knitted structures were studied under relaxation treatments. Results are compared with similar fabrics made from 100 % cotton material. Even though cotton/spandex fabrics knitted with same stitch lengths, their structural spacing and stitch densities vary with the progression of treatments. Similar behavior was also observed with 100 % cotton knitted structures. Under higher machine set stitch lengths (i.e., lower fabric tightness factor), higher structural spacing and lower stitch densities were resulted and those variations significantly affected on the air permeability variations of knitted structures. 1×1 rib knitted structures showed significantly higher air permeability than single jersey structures and it is more prominent with cotton rib structures. However, cotton/spandex 1×1 rib and single jersey structures have not showed such significant deviations. Air permeability of cotton/spandex and 100 % cotton rib and single jersey knitted structures decreased with lower machine set stitch lengths (i.e., at higher fabric tightness factors). There was a correlation with fabric tightness, air permeability, areal density and fabric thickness such as knitted fabrics became tighter, their weight and thickness were higher, while their air permeability was lower. Thus, fabric areal density and fabric thickness are positively correlates to machine set stitch length?1 (fabric tightness factor). Air permeability of a knitted structure depends on material type, knitted structure, stitch length, relaxation treatment, structural spacing and stitch density. 相似文献

Microorganisms can lead to functional, hygienic and aesthetic (e.g. deterioration, staining) problems on textile products.
Natural fibers especially cotton are more easily affected by microorganisms. Blending of cotton fibers with antimicrobial
fibers can enhance the protective properties of products against microorganisms. Demand of antimicrobial performance from
the products changes depending on the application area. Therefore determination of suitable antimicrobial fiber quantity for
the desired application is important. In this study the spinning performance of SeaCell Active/cotton blended open end rotor
yarns and antibacterial activities of fabrics produced by these blended yarns were investigated. Five different cotton/SeaCell
Active blended slivers with SeaCell Active content from 3 % up to 53 % were prepared on drawframe machine and all slivers
were spun into yarns on open end rotor spinning machine at a yarn count of 20 tex with αTt=3827 twist coefficient. The effects of rotor speed, opening roller speed, rotor, opening roller and navel type on the quality
parameters of SeaCell Active/cotton blended yarns were investigated. Tensile properties, hairiness, unevenness and IPI values
of the yarns were reported. All types of cotton/SeaCell Active blended yarns were knitted on a circular knitting machine.
Antibacterial activity of the fabrics was analyzed quantitatively. Antibacterial tests showed that good antibacterial activity
can be achieved after several washings even with 3 % of SeaCell Active fibers in fabrics. 相似文献
