Quilt production line increases quilt gripping power

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

In the twist test section of the doffed yarn of the diameter of the spun yarn or winding, the yarn is wound in a small diameter and a large bend, and the quilt skin twist spun yarn production line is generally close to or exceeds the twist of the reasonable tube sliver yarn. The dynamic strength of the yarn is very high, at the same strength as the police yarn, it should not cause damage. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.

The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.

The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. But in fact the larger yarn ratio is as many ends as possible, on the one hand it is definitely a factor of tension, and on the other hand, due to the strong grip on the power yarn rollers are far away from the boy cops. The quilt production line can improve the evenness of cotton yarn and reduce the strength and weakness of the enterprise: 1. The rational selection of the composition of raw cotton and cotton staple fibers and the fineness of the spinning sliver has a strong and close relationship with hardness.

The use of fine fibers and low short fiber content is beneficial to improve the evenness of the finished yarn and improve the strength of the yarn. For stable production, it should be made with long-term, stable cotton composition. 2. Improve the quality of semi-finished products For spun yarn, the quality of semi-finished products is concentrated in the yarn group. The inherent development quality of the roving (the parallel direction of the fibers and the degree of separation) and unevenness can directly affect the spun yarn. Uniformity and strength.

It should be possible to prevent the rotten rovings from causing weak loops in the sliver and increasing the occurrence of end breaks by controlling the yarn reserve as much as possible to a minimum necessary level. In addition, the residual neps impurities in the roving towel will interfere with the management of the spun yarn pulling and winding control process, destroy evenness or increase the rapid end breakage. 3. Under the premise of sufficient grip strength, the yarn drafting process parameters should be reasonably selected, the twist coefficient of the roving should be appropriately increased, the back belt spacing should be appropriately reduced, and the first type of drafting process should be adopted to reduce the detail length.

Not only does it improve yarn dryness and strength, but it also reduces end breaks. Reasonable use of the polymerizer is beneficial to improve the yarn strength. This is a proven experience in production.

Typically the difference between using and not using an aggregator can be 50-100 points. The relationship between sliver and end breaks, in addition to reducing the width of the sliver and the dynamic strength of the spinning section, also prevents the loss of fibers at the edge of the sliver, reduces fly, and does not easily generate a drum that wraps around, which also helps to reduce end breaks.
