Wet spinning multifunctional postprocessing integrated equipment and processing method

Abstract

The invention discloses multifunctional integrated equipment suitable for wet spinning fiber postprocessing. A postprocessing technology comprises the steps of drying, drafting and heat setting. The equipment particularly comprises a drying functional region, a drafting functional region and a heat setting functional region and is an integrated landing structure. The equipment has the advantage that the occupied area is small, the processing effect of industrial production is achieved, and the defects of the postprocessing equipment in the industrial production process that a processing line is lengthy and complex are overcome. The whole size of the equipment is L / W / H=2,500 / 1,500 / 2,800 mm, the drafting region and the setting region both adopt the mode that one chamber has multiple purposes, the total drafting multiple is 0-20, and the equipment is suitable for scientific research or small batched product production and amplification experiment in industrial simulation.

Description

technical field [0001] The invention relates to a multifunctional integrated equipment for chemical fiber post-processing, in particular to post-processing equipment for wet spinning. Background technique [0002] In the chemical fiber production industry, the traditional wet spinning process is complicated, and most of them are distributed and independent assembly line operations, that is, the process includes coagulation forming, washing, oiling, drying, drawing, heat setting, winding and other processes. Each process has corresponding independent processing equipment, and the whole spinning process is long and occupies a large area. In conventional chemical fiber production, in order to obtain chemical fibers with excellent comprehensive physical and mechanical properties, a complex heat treatment process is required for the fibers. Different fiber varieties and different forming methods have different post-treatment processes. Post-treatment processes mainly refer to dr...

AI Technical Summary

Problems solved by technology

Drafting and heat setting are divided into various forms according to the working medium and working method. The post-treatment process of different fibers needs to be matched with different processing methods, which makes the post-processing process complicated and diverse. Some commonly used processing methods such as wet heat drafting , dry heat drawing, tension heat setting and relaxation heat setting, each process is completed by independent equipment, and the production line is long and complicated

This kind of large-scale independent sub-process equipment is more suitable for large-scale large-scale production, but it is difficult to implement for scientific research and trial spinning of small-batch products, and the feasibility is poor.
