间隔层结构参数对纬编间隔织物压缩性能的影响
|
摘要
采用4根16.6tex(150D)涤纶低弹丝为表面纱,0.10、0.12mm涤纶单丝为间隔丝,在机号E14的电脑横机上通过改变间隔丝的集圈方式、直径及密度编织了12种不同结构参数的纬编间隔织物;测试了织物的压缩性能,从应力-应变曲线、压缩功和压缩回弹性三方面考察了间隔丝的3个参数对纬编间隔织物压缩性能的影响。结果表明对于表面纱为低弹涤纶丝的间隔织物,在一定范围内间隔丝的集圈隔针距及直径的减小和间隔丝密度的增加可使织物具有更好的抗压能力;压缩功和压缩回弹性基本上随间隔丝集圈隔针距及间隔丝直径的增加而降低;而间隔丝密度的增加大都使织物的压缩功提高及压缩回弹性降低。
Four 16.6 tex(150 D)polyester DTY were used as surface layer yarns,0.10 mm and 0.12 mm polyester monofilaments as spacer yarns,twelve kinds of weft-knitted spacer fabrics with different structural parameters were prepared on the computerized flat knitting machine of gauge E14 by changing the tucking method,diameter and density of the spacer filament.The compressive tests were carried out on these fabrics.The effects of the three parameters of spacer filament on the compression properties of the fabrics were investigated from stress-strain curve,compression work and compression resilience.The results showed that for the spacer fabric whose surface yarn was polyester DTY,within a certain range,the decrease of the tuck connecting distance and the diameter of the spacer filament as well as the increase of the spacer filament density could make the fabric have better compressive capacity.The compression work and compression resilience of fabric basically decreased with the increasing of the tuck connecting distance and diameter of the spacer filament.The rising of spacer filament density enhanced the compression work of the fabric and reduced its compression resilience.
