第一代嵌入式复合纺纺纱工艺与纱线性能的研究
|
摘要
复合纺纱技术可以提供更丰富特征、组合和结构的纱线,提供不同纤维配伍的可能,产生各种变异纱系,开拓纱线的品种,因此,复合纺纱已成为纺纱技术发展的趋势。第一代嵌入式复合纺纱是一种新型纺纱技术,是在复合纺的基础上发展起来的,在环锭细纱机上经过改装后即可直接进行加工。第一代嵌入式复合纺纱系统具有独特的纺纱设计,短纤维先与长丝进行扭缠复合,然后再与另一股复合纤维束进一步加捻复合,能够使得短纤维须条很好地嵌入成纱主体中,使得纱线毛羽明显降低;稳定的长丝大三角平台能够有效消除短纤维须条意外牵伸,成纱条干好;长丝与短纤维有效地相互嵌入,纱线强力得到增强。因此嵌入式复合纺纱系统能够明显改善成纱质量,提高了纤维纺纱利用率。
对纺纱工艺中粗纱与粗纱间距、粗纱与长丝间距、偏心距、捻度以及长丝预加张力等进行单因素分析,探讨了工艺参数对第一代嵌入式复合纺纱线性能的影响规律,并分析了产生此性能的原因。实验结果显示在其他工艺参数相同时,最佳成纱间距为粗纱与粗纱间距12mm,粗纱与长丝间距2mm,纺纱中心点偏移距离-2mm。
为了了解第一代嵌入式复合纺的优势,对环锭纺、赛络纺、sirofil纺、第一代嵌入式复合纺等各种纺纱方式作出实验对比研究。结果显示,第一代嵌入式复合纺强伸性比环锭纺、赛络纺、sirofil纺较好,毛羽较少,条干较均匀。同时由于第一代嵌入式复合纺存在缺陷,徐卫林教授提出了第二代嵌入式复合纺,为了解两者性能的差异,在实验上对其作出了比较分析。
在成纱机理方面,建立了第一代嵌入式复合纺在准静止状态下的力学模型,通过流体力学的动量守恒方程和能量守恒方程就确定了小汇聚角之间的关系,同时得出只有捻系数设计适当的情况下,纺纱过程较稳定,纱线性能较好。同时对第一代嵌入式复合纺的加捻过程作了比较详细的分析,对生产实践有一定的指导意义。
The compound spinning can produce a characteristic, combinatorial and structural yarn, provide the possibility of compatibility of the different textile fibers, bring some variant yarns, and expand the variety of yarns. Therefore, it has become a tendency. The first embedding composite spinning is a new spinning technology which is developed in the base of composite spinning. The yarn can be outputed directly on the traditional ring spinning system which is reformed. The system has unique design. First, the short fibers and the filaments are wrapped and then are combined with another composite fibers. So short fibers are embedded well in the body, and are reduced signficantly in yarn hairiness. Stabily triangular platform can effectively eliminate accident drafting. And the yarn is very good. The filament and staple fiber are embedded in an effective manner, which forms a stable yarn and the stength is enhanced. Therefore, the system can signficantly improve the quality, and increase utilization of the fiber.
The influence of various factors, including roving spacing, roving and filament spacing , eccentricity, twist factor and filament pre-tension was examined in technology. And the effect of the factors on performance of the first embedding composite spinning was also studied for analyzing the results of the performance. The results show that the optimal condition was 12mm in roving spacing, 2mm in roving and filament spacing, -2mm in eccentricity under the same experimental parameters.
A comparative study of ring spinning, sirospun, sirofil, first embedding composite spinning was performed to realize the advantages of first embedding composite spinning, indicating that first embedding composite spinning had high performance of strength and elongation, low hairiness, better uniform evenness in comparison to ring spinning, sirospun, sirofil. Meanwhile, because of the drawbacks of the first embedding composite spinning, the second embedding composite spinning was established by Professor Xu. To understand their performance, the analysis was performed on experimental datas.
In terms of mechanism, a dynamic model of first embedding composite spinning in pseudo stationary condition was established. The convergence angle was obtained to solve the imbalance problem of first embedding composite spinning. Under the condition of suitable twist factor, the result was obtained that the process of yarn was the more stable, and performance of yarn was better. The twist of first embedding composite spinning was analyzed in detail to guide production and practices.
