Linen yarn warping and slashing technology

Abstract

The invention provides a linen yarn warping and slashing technology. The linen yarn warping and slashing technology is characterized in that the linen yarn warping and slashing technology comprises the following steps that (1) linen yarns are dug out of bags, arranged on a tray, sleeved with a nylon net and then pulled into a weaving workshop with the constant temperature of 30 DEG C to regain moisture for 12 hours; (2) a deviation type tension control technology is adopted, wherein the linen yarns equal to or more than 21 pieces are watered and humidified, the linen yarns located in the middle part of a warping frame are controlled by using six lattices of tension, and four pieces of the linen yarns on each of the two sides of the middle part of the warping frame are controlled by using ten lattices of tension; the linen yarns less than 21 pieces are not humidified, the linen yarns located in the middle part of the warping frame are controlled by using seven lattices of tension, four pieces of the linen yarns on each of the two sides of the middle part of the warping frame are controlled by using ten lattices of tension; (3) when slashing is carried out, an upper slashing roller, a press slashing roller and a contact roller in a slasher are all in an on state, and the linen yarns pass through the slasher, a drying drum and a waxing roller in sequence and then enter a front machine lease area. The linen yarns processed by adopting the linen yarn warping and slashing technology is good in quality, and weaving machine speed, efficiency and specific yield can be improved significantly.

Description

technical field [0001] The invention provides a warping and sizing process of flax yarn, which belongs to the technical field of textiles. Background technique [0002] Flax fiber is soft, tough, shiny, wear-resistant, low water absorption, fast water dispersal, high expansion rate after moisture absorption, can make textiles tight and not easy to permeate, so it is an excellent textile raw material. Linen fabric has a good health care effect on the human body, so it has been favored by more and more consumers in the international and domestic markets. [0003] Sizing is a very important link in the weaving preparation process. Its quality directly determines the level of weaving efficiency and product quality, especially for hemp fabrics. In the processing of hemp fabrics, the more prominent problems are that the surface hairiness of the yarn is many and long, long and hard, the hairiness is difficult to fit, the sizing has poor wear resistance and is easy to break, the we...

Problems solved by technology

In the processing of hemp fabrics, the more prominent problems are that the surface hairiness of the yarn is many and long, long and hard, the hairiness is difficult to fit, the sizing has poor wear resistance and is easy to break, the weaving efficiency is generally not high, and the product quality is low. Poor, there are many falling objects in the weaving workshop, and the relative humidity requirement is high, which makes the production environment worse
