多组分纤维论文：多组分纤维混纺纱工艺设计与质量控制【中文摘要】现如今,人们生活水平不断提高,健康环保意识不断增强,人们也越来越关注于纺织品的多功能性。利用不同的纤维原料进行多组分混纺,可以充分利用各种纤维的优点,实现其性能的互补性。这为开发出具有多功能性能、外观独特的新型多组分纱线以及面料提供了基础。目前,流行面料的新方向是通过选择适当的混纺比、合适的生产工艺,从而生产出能够符合市场特殊要求的纱线,这也是纱线开发的一个重要趋势。如何根据组成混纺纱中的纤维性能来预测和估计成纱以及最终纺织产品的性能,关键是选择合理的各组分纤维的混纺比,从而使获得的纱线和最终产品达到最优化。本论文主要包括五部分：第一部分对多组分纤维混纺的及意义、国内外研究状况、研究内容及思路做了简要的概述；第二部分以细旦抗起球腈纶/维劳夫特/牛奶蛋白纤维多组分混纺纱为例介绍了多组分混纺纱的开发及纺纱工艺分析；第三部分描述了多组分混纺纱生产过程中工艺的控制因素,包括混纺比对混纺纱的影响、混纺比例的确定、原料的混合、纤维在纱线中的排列等；第四部分主要是分析了细旦抗起球腈纶/维劳夫特/牛奶蛋白纤维多组分混纺纱的性能；从原料的选择与混合,混纺比等方面完善纺纱工艺；从断裂强度、断裂伸长率、条干不匀、毛羽等性能指标对多组分混纺纱进行了分析研究。第五部分概述了其质量检测标准。【英文摘要】With the improvement of peoples living standard as well as the strengthening of health and environmental protection consciousness, more and more people give the enormous attention to the textile versatility.Using different fiber materials in multicomponent blended yarns, it can make full use of the advantages of various fibers, and realize its performance of complementary.This provides basis for development performance and appearance unique in new multicomponent functional yarn and fabric.Through the reasonable blending ratio and appropriate production craft, then produced yarns with special requirements, this has become a kind of new direction of the currently popular yarn fabric, and this also become one of the important trend of yarn development.The key of a reasonable choice of each component fibers blended and get the optimal performance yarn and the end product is to predict the yarn and final product performance according to the performance of fiber in blended yarn.Five parts are included in this thesis:The fist part has a brief introduction about the purpose and significance of multi-composition fibers blended, the develop and research status in home and abroad, and the research contents and ideas; the second part take anti-pilling acrylic fiber/viloft fiber/milk protein fiber multi-composition blended yarn as an example,which introduced the development of component blended yarn and the spinning process analysis; the third part mainly describes control factors of the multi-composition blended yarn production process technology, which include the influence of blended yarn, determination of blending proportion of blending ratio, and the mix of raw material, the arrangement of the fiber in the yarn; The fourth part mainly analyzed the properties of acrylic fiber/viloft fiber/milk protein fiber multi-composition blended yarn; from the selection, blending and blending countermeasures of raw material to improve the spinning process; and analyzing components of blended yarn from breaking tenacity, elongation at break, hairiness of such performance index. The fifth part Outlines its quality inspection standard.【关键词】多组分纤维 混纺纱 混纺比 纺纱工艺 质量控制【英文关键词】Multi-composition fiber Blended yarn Blending ratio Spinning craft Quality control【备注】索购全文在线加好友：1.3.9.9.3.8848 同时提供论文写作一对一指导和论文发表委托服务【目录】多组分纤维混纺纱工艺设计与质量控制摘要2-3Abstract3第一章 前言6-131.1 多组分纤维混纺的研究目的及意义6-71.2 国内外相关课题研究7-101.3 本文研究思路10-13第二章 多组分纤维混纺纱的开发13-232.1 多组分纱线的原料选择13-142.2 抗起球腈纶/维劳夫特/牛奶蛋白纤维混纺纱的开发14-182.2.1 纱线各组分的分析152.2.2 纤维的介绍15-182.2.3 纤维的物理性能182.3 纺纱工艺分析18-222.3.1 纺纱工艺路线192.3.2 混合方法192.3.3 预处理19-202.3.4 牛奶纤维和腈纶纤维清梳主要工艺原则20-212.3.5 维劳夫特纤维纺纱工艺21-222.4 小结22-23第三章 多组分混纺纱的工艺控制23-303.1 混纺比对混纺纱的影响23-243.1.1 混纺比对混纺纱强度影响的理论分析233.1.2 混纺比对条干影响的理论分析23-243.1.3 混纺比对毛羽的影响243.2 混纺比例的确定24-263.2.1 根据产品用途和质量要求确定混纺比253.2.2 根据纤维的强伸度确定混纺比25-263.3 混纺比的控制26-273.4 纤维在纱线中的排列27-293.4.1 纤维在纱线中的转移27-293.4.2 纺纱方法和纤维转移的影响293.5 小结29-30第四章 多组分混纺纱的性能研究及评价30-364.1 纱线基本性能测试30-314.1.1 成纱强力304.1.2 毛羽304.1.3 条干均匀度30-314.1.4 纱线捻度314.2 纱线质量评价指标31-334.2.1 捻度324.2.2 重量偏差324.2.3 条干均匀度32-334.2.4 强力334.3 成纱性能测试与分析33-354.5 小结35-36第五章 质量检测标准36-445.1 制定依据365.2 内容特点36-385
