Problems solved by technology

[0003] Because the original degumming production method takes fiber fineness as an important basis for spinning different spun yarn counts, it does not fully understand the problems that arise in the degumming production process when considering the length of raw hemp, which is more important than fiber fineness. , so in actual production, it brings many problems to degumming quality, processing cost, process flow, manual to mechanized automation, etc.

Abstract

The invention discloses a subsection ramie unglued producting method which determines the different branch numbers according to fiber length, it includes raw ramie pre-process, coming unglued, post process, its character lies in: in pre-process, the raw ramite are divided into segments, the length is from 50 to 400 mm. The invention shortens the craft, and enhances the quality of coming unglued.

Description

One technical field [0001] The invention relates to a segmented ramie degumming production method. It belongs to the technical field of production and processing of ramie fiber raw materials. 2. Background technology [0002] The production and processing of the original ramie fiber starts from the degumming and binding. The fiber fineness of the raw hemp is used as an important basis for spinning different counts of the spun yarn. The raw hemp variety of about 1400 metric counts is used as the raw material for low-count spun yarn. A degumming production method designed by using raw hemp varieties at about 1800 metric counts as 48 spun yarn raw materials and 1600 male ramie varieties as 36 spun yarn raw materials, (Ramie Spinning and Ramie Textile Mills) Design two books provided) and design the original degumming production process. [0003] Because the original degumming production method regards the fineness of the fiber as an important basis for spinning different yarn counts...
