缝纫机针对羊毛防寒服防钻毛性能的影响

羊毛防寒服在服用过程中会出现不同程度的钻毛现象，其中通过针眼的钻毛量是比较明显的，它降低了羊毛防寒服的美观性和服用性能。本文参考 GB/T 12705-2009《织物防钻绒性试验方法》中规定的织物防钻绒性试验方法，并根据实际情况对试验参数进行调整，模拟羊毛防寒服在穿着过程中所受到的各种挤压、揉搓、碰撞等作用力，计数从面料和针眼钻出的羊毛量，分析在不同织物密度和缝纫机针下的钻毛量及其规律。研究表明较小型号圆头机针可明显降低羊毛纤维的钻出量，这一技术手段可用于羊毛防寒服的生产实践，并有效地提升羊毛防寒服的防钻毛性能。

Influence of sewing needle on fiber projecting-out srsistance of winter woolen garment

There are some wool fibers drilling out of the winter coat filled with wool during wearing process. The more obvious one is coming from sewing needles, and the capability of beauty and wearing are debased. The fabrics-testing method for anti-penetration capability of feather and down ( GB / T12705—2009) was referred, and the tested parameter was adjusted. simulating all kinds of extrusion, knead, collision force of the wool winter coat during wearing process, the quantities of wool fibers drilling out were counted, and the disciplinarian distributing of wool fibers drilling out based on different fabric density and sewing needles were analyzed .The result shows that using smaller and round shape sewing needle is an effective way to reduce the quantities of wool fibers drilling out. This technique method can be used in the manufacture practice and advance the anti-penetration capability of winter coat filled with wool.
