Method for ramie wool type spinning

Abstract

The invention provides a method for ramie wool type spinning, which is characterized in that after the existing softening process, improved ramie opening equipment and improved ramie combing equipment pull the degummed ramie apart and comb the degummed ramie into wool type fibers with the lengths of 70-85mm, and the existing wool type spinning equipment is then used for the worsted spinning process. The method provided by the invention is used for overcoming the defects of the prior art, the equipment and technologies of the opening and combing process of the present ramie spinning are improved, the ramie fibers are processed to be with the lengths of the wool type fibers, so the advanced wool spinning equipment can be used for spinning the ramie fibers directly, and the quality and efficiency of the ramie spinning are improved.

Description

technical field [0001] The invention relates to a wool-type spinning processing method of ramie, which belongs to the technical field of textiles. Background technique [0002] Conventional ramie spinning process is: dry hemp → soft hemp process → opening process → carding process → pre-combing process (2 steps) → combing process (1~2 steps) → needle carding process (4 steps) → roving Process → spinning process. [0003] The length of ramie fiber is long, generally about 200-400mm, and the fiber length of general spinning should be controlled below 120mm. Therefore, in order to ensure the smooth progress of ramie spinning, in the conventional ramie spinning process, the opening and carding processes The main purpose of the ramie fiber is to pull off the excessively long ramie fiber so that the length can meet the requirements of spinning. However, the traditional concept believes that the ramie fiber itself is very long, and it is not conducive to the quality of the yarn i...

Problems solved by technology

[0009] However, this stretch-cut spinning method is only a reform of opening and carding in ramie spinning, so as to reduce the problem of uneven fiber length, especially ultra-long fibers, and its subsequent processing is still limited to the use of existing Ramie spinning equipment, that is, the ramie fine dry hemp is cut into a length of 90-120mm (the stretch-cut distance is 90-120mm), and the fiber length after stretch-cut is still very long, which is longer than the 65-85mm of wool fiber. Therefore, although its processing route refers to wool spinning, it cannot be spun directly on wool spinning equipment, but must be processed on ramie equipment.

In addition, although the pulling and cutting process can replace the opening process and carding process in the original ramie spinning, the production efficiency is much lower than that of opening and carding.
