研究PTT棉交织物的弹性.选取纬纱均为PTT无捻低弹长丝的11种交织物,测试了其弹性伸长率和弹性恢复率,并采用多元线性回归方法分析了PTT棉交织物结构参数与弹性伸长率和弹性恢复率的关系.研究结果表明:织物的组织浮长对织物弹性伸长率的影响最大,其次为经向上机紧度;织物的弹性恢复率主要受纬纱细度和织物在弹力方向伸长的影响. 相似文献

研究了不同张力条件下,干热和湿热处理后的PTT纤维及毛/PTT混纺纱的弹性及拉伸性能.松弛条件下的干热和湿热处理导致了PTT纤维初始模量的降低、延伸性能的增加.一定张力条件下的干热和湿热处理可以防止PTT纤维初始模量的降低,且在张力小于6 cN/tex、150℃干热条件下处理PTT纤维将提高其回弹性能,这可能是由于张力作用导致了非晶区大分子链"Z"构象取向增加以及高温作用导致的结晶增加.这些现象在毛/PTT混纺纱弹性测试中也得到了验证. 相似文献

用KES测试分析了PTT的短纤织物、DTY长丝织物和PTT/PET双组分并列复合长丝织物的弹性伸长率、弹性回复率、塑性变形及抗疲劳特性,并且将其性能与氨纶、普通化纤织物(涤纶、锦纶织物)进行比较发现,PTT各种形态织物的弹性伸长均比普通化纤织物的弹性伸长大,比氨纶织物的弹性伸长小;在低负荷下,其回复性能均比普通化纤织物小,塑性变形比普通化纤织物大;3种形态的PTT针织物中PTT/PET双组分并列复合长丝织物的弹性伸长最大,回复性能最好,PTT短纤织物的回复性能最差,塑性变形最大。 相似文献

Surface roughness properties of wool fabrics are one of the important parameters of clothing quality and hand feeling. This paper presents a comparison between surface roughness characteristics of wool fabrics produced from different constructional parameters such as warp and weft yarn density, weft yarn count, and weave pattern. Roughness values of fabrics were affected by constructional parameters and the effects were related to fabric cover, fabric thickness, and crimps of yarns in fabric structure. A general overview of the results showed that surface roughness of wool fabrics decreased and the effect of changes in structural construction decreased as cover of fabrics increased. 相似文献

Effects of abrasion on surface roughness properties together with appearance of woven wool fabrics have been investigated. The effects of weft yarn count, weft yarn density, and weave pattern on fabric surface roughness after abrasion were researched. Surface roughness values of control fabric (not abraded) and abraded fabrics after four different abrasion cycles were discussed according to different fabric constructional parameters. It was observed that the greatest decreases in surface roughness values after abrasion were observed in loose fabric structures which had the highest initial fabric surface roughness values (coarse yarn, low yarn density, and low yarn intersection). The results showed that change of roughness properties of wool fabric surfaces after abrasion depends on the initial surface roughness values and on the amount of contact area of fabrics based on the fabric constructional parameters. 相似文献
