Effect of cotton fiber and yarn characteristics on color variation in woven fabric dyed with vat dyes

The aim of this study was to investigate the effect of cotton fiber and yarn characteristics on the color variation of woven fabrics dyed with vat dyes. A fabric length of 31?m was woven so that each meter of the fabric comprised weft yarns of slightly different cotton fiber or yarn characteristics as compared to the other. The woven fabric was pretreated and dyed with vat dyes using industrial-scale, pad-dry-chemical-pad-steam process. After dyeing it was found that the fabric containing weft yarns made from cotton with higher reflectance (Rd) values gave poor color strength as compared to that of lower Rd values. Fabric comprising combed weft yarns showed better color depth (K/S) values as compared to that comprising carded weft yarns made from the same raw cotton. Furthermore, the fabric comprising finer- or lower-twist weft yarns gave higher color depth as compared to that with coarser or higher-twist weft yarns. It was concluded that slight variations in the cotton or yarn characteristics in the weft yarns could result in significant shade variations in the vat-dyed fabric.     

酚醛纤维织物热湿舒适性的灰色聚类分析

为了解酚醛纤维织物的热湿舒适性,将酚醛纤维织物应用于消防领域,以酚醛纤维织物及消防服常用的阻燃棉布、芳纶1313 织物、聚酰亚胺织物为研究对象,对隔热性、保温性、透湿性、透气性和输水性这5 个指标进行测试,研究相同面密度的不同种类织物的热湿舒适性。利用灰色聚类分析理论对5 个指标进行聚类分析,对这4 种织物在不同环境下的热湿舒适性能做了综合评价。结果表明：在高温条件下,酚醛纤维织物具有较好的热湿舒适性,聚酰亚胺织物与阻燃棉布次之,芳纶1313 织物最差;在低温条件下,酚醛纤维织物也具有良好的热湿舒适性,聚酰亚胺织物次之,芳纶1313 物与阻燃棉布最差。     

环锭纺纱和紧密纺纱罗纹针织物性能及其他物理性能

所有数据显示紧密纺纱织物的性能及其他物理参数优于精梳纱织物。相对于传统的环锭纺,紧密纺纱的毛羽指数低、强度高、条干均匀。紧密纺和环锭纺纱线结构上的差异明显地影响其织物性能、因此,尽管所有其他织物参数都相同,紧密纺纱生产的针织物相对于环锭纺纱针织物还是有着较短的线圈长度、较高的面密度、断裂强度、断裂伸长、顸破强力,以及更少的起毛起球。紧密纺纱线生产的针织物仅耐磨性稍差于环锭纺纱针织物．

Effect of input tension of inlay yarn on the characteristics of knitted circular stretch fabrics and pressure generation

Stretch fabrics are used in manufacturing pressure garments to exert pressure over specific body parts in medical conditions like venous and lymphatic disorders, scar management, and bone and muscle injuries. The amount of therapeutic pressure required in each medical condition is different; therefore, there is a need to engineer the stretch properties of garments to match the requirements in each case. Limited information is available on the relationship between fabric properties and the pressure generated on the body. In this paper, an attempt has been made to study the effect of inlay yarn pre-tension at the time of manufacturing of stretch fabrics on the pressure generated by the garments. Results show that change in inlay pre-tension significantly changes the structural characteristics of the fabric but the load elongation behavior remains unchanged up to 100% extension. Pressure exerted on rigid cylindrical tubes increases with reduction factor of the fabric tube and the curvature of the cylinder.     

纤维的长度特征对成纱的影响

为探讨纤维长度对纺纱过程和成纱质量的影响,通过理论分析以及对一系列实验结果的分析和总结发现:在纺纱过程中,纤维长度不仅影响加工工序的选择,而且影响最终的成纱质量.由于纤维在纱条中呈随机排列,过长的纤维会导致成纱均匀度恶化,并对纺纱过程有负面作用;而太短的纤维会在一定程度上影响纱的强力.因此,选择长度适当的纤维可以兼顾纺纱和成纱综合质量.

Thermo-physiological comfort properties of double-face knitted fabrics made from different types of polyester yarns and cotton yarn

Double-face knitted fabrics with hydrophobic inner and hydrophilic outer layers are characterised by their advantageous thermo-physiological comfort property that facilitates the transport of sweat from skin to outer fabric layer where it can be evaporated easily. In this study, for the production of double-face knitted fabrics, cotton yarn as hydrophilic yarn type and five different polyester filament yarns consisting of standard polyester, hollow polyester, micro polyester, textured polyester and textured micro polyester as hydrophobic yarn type were used. In order to determine the thermo-physiological comfort properties of the fabrics, air permeability, water vapour permeability, thermal conductivity, thermal resistance and overall moisture management capacity were measured. The results were comparatively analysed using statistical methods. The experimental results demonstrated that the polyester-type yarns and the combinations of them with the cotton yarn in fabric layers affected the thermo-physiological comfort properties significantly. The fabrics with polyester-type inner face and cotton outer face showed the best moisture transmission properties.
