摘要
就新型仿棉假捻变形纱的纱线结构、卷曲性能、强伸性能、条干均匀度、表面浸润等性能进行了全面研究,并与纯棉纱和常规假捻变形纱进行对比分析。结果表明:较常规假捻变形纱,新型仿棉假捻变形纱具有明显的粗细节结构,使其具有一定的短纤纱外观特性;其热收缩率和和卷曲收缩率较常规假捻变形纱大,这可能与其纱体中含有2种长丝组分有关;其断裂强度和断裂伸长率明显比常规涤纶假捻变形纱小。在棉纱断裂伸长率范围内,新型仿棉假捻变形纱的强伸曲线与棉纱强伸曲线基本吻合;而其与水滴的接触角比纯棉纱和常规假捻变形纱小,水滴在新型仿棉假捻变形纱表面快速铺展浸润,表明该纱具有优异的导湿性能。新型仿棉假捻纱总体外观形态具有一定的仿棉效果,而其强伸、弹性回复和导湿性能超越纯棉纱。
In this paper, the structure, tensile property, crimp, evenness and surface wetting of the new cotton-like false-twist polyester filament textured yarn were studied by comparing with pure cotton yarn and traditional false-twist polyester filament textured yarn. The result shows that： the new cotton-like false-twist polyester filament textured yam has an obvious thick and thin structure, which makes it a cotton-like appearance to some extent. The tenacity and elongation at break of cotton-like false-twist polyester filament textured yarn are much lower than those of traditional false-twist polyester filament textured yarn whilst its stress-strain curve matches that of cotton yam within the cotton yarn breaking rate. The thermal shrinkage and crimp contraction of cotton-like false-twist polyester filament textured yarn are larger than those of traditional false-twist polyester filament textured yarn, which may he attributed to the hi-component structure of the yarn. The contact angle of cotton-like false-twist polyester filament textured yarn is much smaller than that of pure cotton yarn and traditional false-twist polyester filament textured yarn. Water drop spreads quickly on the surface of cotton-like false-twist polyester filament textured yarn, which indicates the yam has excellent water transmission ability. In summary, the new cotton-like false-twist polyester filament textured yarn has a cotton-like appearance to some extent, and its tensile, elastic recovery and moisture transmission property are better than that of pure cotton yarn.
