纺纱工艺流程功能解析(中)

Functional Analysis of the Spinning Process Flow

为了合理控制纱线产品质量和优化纺纱工艺设计,探讨了纺纱工艺流程中各项纺纱功能的构成及相互关系,将各工序从功能上划分为基础层(包括松解和集合)、主层(包括开松、梳理、牵伸和加捻等)、次层(包括除杂、混和、并合和精梳等)和辅层(卷绕成型),具体分析每个层次实现各项功能要求的方式与控制措施;重点阐述纤维松解、集合等纺纱主要功能要求、完成方式和相关工艺要求,特别是梳理器材之于松解、集束器材之于集合的影响。指出:在纺纱工艺流程中,所有的工艺技术始终围绕纤维的松解和集合展开;松解是集合的基础和前提,其目的是为了更好地集合。

To reasonably control yarn quality with optimized spinning process, probing is done into the functional composition of spinning processes and the relationships in-between, the processes are functionally classified as the base layer（releasing and collecting）, the main layer （opening, carding, drawing and twisting etc.）, secondary layer （cleaning, mixing, drawing and combing）and auxiliary layer（winding formation） . Specific analysis is done to the way and con- trol achieving the function of each layer.Highlight is given to fiber releasing and collecting re- garding functional requirements, way of achieving and the relative processes, specifically, re- lieasing in carding elements and collecting in collecting elements.It is pointed out that in all the spinning processes flow,all the technologies are involved with fiber releasing and collecting, re- leasing is the premise and basis of the collecting, and the better collecting.
