汉麻/黏胶局部保暖型无缝内衣的设计与性能测试

摘要

In order to improve the partial thermal insulation of seamless underwear,hemp / viscose blended yarns with antibacterial property were selected as the raw materials for knitting.In view of the human body parts which are easy to catch a cold,four different knitting structures were designed to make seamless underwear.Meanwhile the breathability and heat retention property were tested and analyzed.Results indicate that 1 × 3 mock rib hosts best warmth retention among all the other structures.Its warmth retention rate is 16％ and 60％ higher than that of plain plating and single jersey,respectively.The single jersey structure has the best air breathability,which is 1.6 times and 2.4 times as high as that of the mock terry and plain plating,respectively.Therefore,1 × 3 mock rib and mock terry structures could be chosen to make seamless underwear to achieve better partial thermal performance.%为提高无缝内衣局部保暖性,文中选用具有良好抗菌性能的汉麻/黏胶混纺纱线为原料,针对人体易受寒部位,设计4种不同组织进行无缝内衣的编织,并对其透气性、保暖性进行测试和分析.结果表明:所设计编织的4种组织中1+3假罗纹的保暖性能最好,保暖率分别比纬平针添纱和纬平针高16％和60％;纬平针的透气性能相对较好,透气量分别是真毛圈及纬平针添纱的1.6倍和2.4倍.综合透气性及保暖性,可以设计1+3假罗纹、真毛圈等组织,实现无缝内衣的局部保暖功能.
