Problems solved by technology

[0017] Although the method of producing hemp yarn by composite embedded spinning improves the spinnability of hemp yarn, it can meet the requirements of air-jet weaving in the subsequent process. It can be used as clothing fabrics by using different blending ratios or blending with fibers of different properties. However, it cannot meet the requirements of high-count and high-density fabrics

Abstract

The invention provides a method for producing hemp yarns through vortex spinning. The method comprises the following steps: curing pretreatment of hemp fibers, wherein addition amount of an oil-damp feeding soft penetrating agent is 6-8% of the hemp fibrils by weight, the oil-damp feeding soft penetrating agent comprises the components of: 12-16% of emulsifying agent, 6-10% of softening agent, and 75-79% of soft water, and the moisture regain is controlled between 12% and 15%; a plucker, a bending fiber opener, a fiber opener, a vibrating feed box, a lap machine, a carding machine, a pre-draw frame, a draw and lap combination machine, a combing machine, a draw frame and a vortex spinning machine. The method has the following advantages: the maximum count of the weaved hemp yarns can reach 50; the noil rate is reduced; the flexibility, parallel straightness, spinnability and strength of the fibers are improved; the finished product rate is high; the hemp fibers are protected by adopting the methods of more loosening and fewer beating in slow speed; and the method lays the foundation for normal production through vortex spinning.

Description

technical field [0001] The invention relates to a production method of hemp yarn, in particular to a method for producing hemp yarn by vortex spinning. Background technique [0002] The existing production method of hemp yarn, such as "Composite embedded spinning method for producing hemp yarn" developed by Jihua 3542 Textile Co., Ltd. [0003] The production process is as follows: A002D cotton grabbing machine→A0068 cotton mixing machine→A036C cotton opener→A092 cotton feeder→A076C lapping machine→A186D carding machine→XF1338 strip coiler→SXF1348 doubling machine → FA266 comber → FA303 draw frame (two passes) → A454 roving frame → FA506 spinning frame → AC338RM automatic winder. [0004] Its detailed production process is: [0005] 1. Cleaning process [0006] The main process configuration is: A002D-type catching beater speed 975r / min, the operating efficiency of the catching machine is more than 90%, A036C-type beater uses a comb needle beater, the speed is 450r / min, t...
