011253涤纶/氨纶包覆丝结构与织物弹性之间的关系/现代纺织技术/李海英,李茂松,2001,No1,4～8用正交试验和线性回归分析方法讨论了涤纶/氨纶包覆丝在不同的包覆度、牵伸倍数、涤纶纤度、氨纶纤度情况下对由它作纬纱织造的纬弹织物弹性的影响情况。试验表明:织物弹性的大小,在上机规格一定的情况下,可通过控制纬纱原料的结构参数来达到。要使织物达到需要的延伸率,且残留变形又较小,其一般规律是氨纶芯丝纤度一定,外包涤纶纤度越大,需加包覆度越小;外包涤丝纤度一定,氨纶芯丝纤度越大,需加包覆度越大。在现有工艺参数下,涤/氨弹力机织物的延…

Application of stitch-bonded multi-plies made by using the extended warp-knitting process: influence of pattern and knitting yarn tension on the geometry of the textile fabric

This paper is part of a series dealing with the application of the extended warp‐knitting process for the production of textile fabrics for composites. Further studies will examine the properties of thermoplastic composites and textile reinforced concrete made of stitch‐bonded multi‐plies. It is known that knitting yarn pattern and knitting yarn tension during fabric production affect the properties of stitch‐bonded multi‐plies and composites made thereof. This paper describes the effects of those two parameters on the fabric as produced with the extended stitch‐bonding process. It can be shown in which way pattern and yarn tension can be chosen to reduce compression of the warp threads in the fabric as well as to avoid unwanted displacement of threads caused by handling.     

Air permeability and bursting strength of weft-knitted fabrics from glass yarn. Part II: knit architecture effect

In this study; the effects of loop, skip, and tuck stitch types, and weft-inlay yarn, on air permeability and bursting strength of weft-knitted fabrics from glass yarn were revealed. Due to clockwise rotation of wales and their arrangement being one on top of the other, besides the dramatic shortening of fabrics after their removal from the machine; fabrics with tuck stitches exhibited the highest stitch density, fiber content, and the shortest loop length. This caused the lowest air permeability and the highest bursting strength. Contrary to expectations, weft-inlay yarn did not contribute to bursting strength as much as tuck stitch did. An overall negative correlation between air permeability and bursting strength was disrupted by structures with tuck stitches. While tuck stitches from cotton yarn increased air permeability and decreased bursting strength in previous studies; this study indicated that tuck stitches from glass yarn decreased air permeability and increased bursting strength.     

The Air-permeability Measurement of Open Fabrics by Using Superimposed Fabric Layers

An account is given of an investigation of the dimensional properties of a series of plain weft-knitted fabrics produced from open-end-spun yarns. The results are compared with those for similar fabrics knitted from ring-spun yarns.

It is shown that fabrics knitted from the two types of yarn possess different properties and particularly that the amount of relaxation shrinkage observed in fabrics knitted from open-end-spun yarns is greater than that which occurs in fabrics knitted from ring-spun yarns. The aesthetic properties of fabrics made from open-end-spun yarns are inferior to those of fabrics made from ring-spun yarns, particularly with regard to a lack of stitch clarity and a somewhat harsher handle, although the latter effect is shown to be apparently unrelated to differences in the frictional properties of the two types of yarn.     

Utilization of the yarn pullout test in estimation of the reserved energy of rib knitted fabrics

The yarn pullout test is a prevailing and particular method to evaluate the effects of yarn properties and the structural characteristics of the fabric on the fabric mechanical performance. In this research, a theoretical model of yarn pull out is presented to determine the reserved energy of weft-knitted fabrics with rib 1 × 1 structure. This model is based on the fabric dimensional properties, i.e. stitch length, wale density, yarn diameter and contact angle of yarns. In order to appraise the proposed model, five different double jersey weft-knitted fabrics with rib 1 × 1 structure were produced and exposed to pullout test. Comparison between deviations of theoretical results from experimental results demonstrates that the presented theoretical model exhibits a rational estimation of the reserved energy in these fabrics.
