Study on microclimate conditions for woven fabrics from cotton-acrylic bulked yarn

The present work is concerned with the study of the microclimate conditions with plain woven fabrics produced with cotton-acrylic high-bulk yarns. Cotton-acrylic bulked yarns of various yarn counts, proportion of shrinkable acrylic fibre and twist levels have been prepared as per the three-variable three-level factorial design technique proposed by Box and Behnken to study the interaction effects of the variables on the microclimate conditions. The influence of these three variables on various microclimate conditions i.e. initial increase in microclimate temperature and relative humidity without air flow and drop in microclimate temperature and relative humidity when air flows at 1.12?m/s through the outer surface of fabrics. The response surface equations for all the microclimate parameters have been derived and the contour plots were obtained to analyse the interactive effect of all the variables on microclimate parameters. These bulked fabrics show higher initial increase in microclimate temperature without air flow and lower drop in microclimate temperature with air flow as compared to equivalent 100% cotton fabrics. All the variables were found to have significant effects on microclimate parameters.     

The effect of yarn twist direction on the formability of woven fabrics

This experimental work examines the influence of the yarn twist on the formability of a woven fabric. Consideration is given to the phenomenon of bedding between warp and weft yarns, as affected by the local helix angles of bent yarns. A total of 28 plain weave woven fabrics (four groups, each with seven samples) were produced, using Solospun? yarns as warp and weft threads. The fabric bending length and the initial modulus of each sample were measured from which the formability was calculated. Results indicated that the fabrics in which the warp and weft twists are unidirectional (Z &; Z) have higher formability in comparison to those fabrics in which the warp and weft twists are opposite to each other (Z &; S). In addition, among the former fabrics the highest formability belongs to those in which the total helix angle of the warp and weft is close to 90 degree whereas the lowest formability belongs to the latter fabrics with least amount of twist.

高紧度形状记忆纤维/棉机织物的记忆性能

为探究高紧度状态下形状记忆机织物的记忆性能,设计开发了15种形状记忆纤维（SMF）在经纬向呈不同分布的高紧度形状记忆纤维/棉机织物,与参照织物一起进行形状记忆性能的测试,结果表明：织物的形变固定率（Rf）一致性程度较高;形状回复率（Rr）总体随SMF含量提高有增大趋势,此规律经向比纬向明显;织物某一向的紧度超过一定限度时,经纬纱之间的摩擦阻力将会造成另一向的形状回复性能不足;单向含SMF织物因拉伸载荷对另一向的收缩和剪切效应,使得织物另一向也具有一定的形状记忆性能;高紧度机织物在某一向SMF含量固定（或不含SMF）时,织物另一向的形状记忆性能随SMF含量增加而提高。

Investigation of automated geometry modeling process of woven fabrics based on the yarn structures

Fabric structure has a significant effect on the thermal protective performance of fabrics. Before studying the thermal performance of textiles by numerical methods, it is essential to create geometric models of textile structures. Common fabrics, such as plain weave, 2/1 twill, 3/3 twill, 5/3 satin, and double layer fabric, were modeled using TexGen software. To obtain the input data for geometry simulation of fabrics, geometric measurements were studied. Methods of modeling fabric geometries according to their yarn path function and cross-sectional shapes were introduced. The appearances of the geometric models were very close to the structures of the real fabrics when compared to their light microscopic images. The fabric models were well used to simulate the heat transfer properties of glass fiber fabrics.
