纺纱工艺流程功能解析(下)

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 ect.）and auxiliary layer（winding formation） . Specific analysis is done to the way and control achieving the function of each layer. Highlight is given to fiber releasing and collecting regarding 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 for the better collecting.
