End Use

This study investigates the effect of the blend ratio on recycled blended yarn quality characteristics. Ring-spun yarns of linear density of 23.6, 29.5 and 39.4 tex were produced from five blend proportions of recycled polyester and cotton (0:100, 33:67, 50:50, 67:33 and 100:0). Increasing the recycled polyester content increases the tenacity, elongation at break and hairiness and decreases unevenness, thin places, thick places and neps, while a decrease in linear density increases the tenacity, elongation at break, unevenness, thin places, thick places, neps and hairiness. Statistical analysis reflects that both the blend ratio and linear density have a significant difference on the tenacity, elongation at break, thin places, thick places, neps and hairiness. However, with reference to unevenness, a significant difference is reported only for linear density and not for the blend ratio. The ratio of recycled polyester has a significant influence on the overall quality of recycled polyester/cotton blended yarn. The blending of recycled polyester and cotton can be optimised to meet various end-use requirements.

Abstract The influence of Modal–cotton (MC) fibre blend ratio and ring frame machine parameters such as front top roller loading and break draft on the blended yarn properties has been studied. Compact MC blended yarn samples of 14.75 tex with three different MC fibre blend ratio has been produced in a LR 6 ring spinning frame fitted with Suessen Compact drafting system. A robust design optimisation to minimise the variations of the output yarn properties such as blended yarn tenacity, yarn unevenness and hairiness caused because of the variations in the material as well as machine setting parameters is achieved through the Taguchi parametric design approach. It is found that the maximum compact MC blended yarn tenacity is 23.76 g/tex, which is influenced very much by MC fibre blend ratio but meagrely by top roller loading and break draft. Similarly, the minimum 9.54 U% and 3.59 hairiness index are achieved with 100:0 and 70:30 MC fibre blend ratio, respectively, at 23-kg top roller loading. Statistical ANOVA analysis is performed on the results and optimum values are obtained within the 95% confidential level through confirmation experiments.

The Ideal

Hemp fiber has many excellent properties, but there are certain difficulties in spinning yarn because the fiber is hard and its cohesion is small. Cotton fiber is soft and its length, fineness is uniform therefore has excellent spin ability and can compensate for the shortage of hemp fiber. We developed the knitted fabrics that have moisture absorption and dry-fast properties using the hemp/cotton blended yarn and discussed weft knitting, dying as well as finishing processes. This shell fabric has special performance such as moisture absorption and air permeability, anti-mildew and antibacterial, anti-ultraviolet ray, antistatic, ecological health ect, which is the ideal sports and summer fabric.

In order to understand the influence of the blended ratio of the soybean protein fibers to the properties of blended fabrics, five soybean protein fiber/modal blended fabrics are knitted and tested. By the analysis of the results, the relationship between the properties of the blended fabrics and the blended ratio of the soybean protein fibers are obtained. With the increase of the ratio of the soybean protein fibers, the tensile strength and the elongation of the blended fabrics increase and the tearing strength and bursting strength of the fabric decrease. With the increase of the ratio of soybean protein fibers, the softness increases and the bending length, abrasion resistance of the knitted fabrics decrease.

AbstractDuring the technological processing of staple fibers into yarn drafting, waves are formed which increase the irregularity of yarn linear density and consequently affect the yarn quality. Even a correctly performed technological process does not allow one to completely eliminate yarn faults (thin and thick places, neps) and yarn irregularity. All the yarn imperfections distinctly become apparent in flat textiles made of such a yarn. The quality of the yarn produced should be assessed already in spinning mill, using the results obtained to conclude on the quality of woven or knitted fabrics. Modern metrological laboratories in spinning mills possess Uster Tester 5 (UT5) apparatuses that not only assess the yarn quality with respect to the irregularity of linear density, faults (thin and thick places, neps), or hairiness, but also using the test results obtained make it possible to create a digital image of the predicted appearance of a flat fabric made of the yarn tested. This article presents a computer-aided method of the analysis of the woven and knitted fabric images obtained from UT5 that allows one to assess the significance of particular yarn parameters in the predicted appearance of flat fabrics.

Bamboo fiber reinforced polylactic acid composite is a kind of green composite materials with excellent performance, which is environmental safe and degradable in natural environment. Literature regarding the characteristics of reinforcement and matrix, pretreatment methods, preparation technology and biodegradable nature of the bamboo/ polylactic acid composite was reviewed and a particular bamoo/ polylactic acid composite made by biaxial weft knitted fabrics was developed. The composite demonstrated excellent tensile and flexural performance. In addition, the influence of the linear density of the binder yarns on the mechanical properties of this composite was insignificant.

Spirality arising from loop distortion in single-jersey knitted fabrics is discussed. Test methods for measuring fabric spirality in knitted fabrics are outlined. Results of an experimental investigation are statistically analyzed considering the effects of yarn/fabric construction factors on the spirality behavior of laboratory produced single-jersey fabrics. The study reveals that the steady-state loop shape for the washed/tumbledried knitted specimens is not unique. Accordingly, the construction factors considered in the statistical analyses are yarn linear density, yarn twist factor, fabric tightness factor, and fabric loop shape. The analyses reveal the importance of the yarn twist factor as well as the fabric tightness factor in promoting fabric spirality. Multiple linear regression equations of practical importance for predicting fabric spirality are derived from the experimental results.
