Reduce Mao Yu By Controlling Sizing Equipment And Technology.

The control of increment is closely related to the overall performance of warping machine. The following points are good for reducing warping hairiness.

There is no abrasion on the yarn passage, including tension sowing, stopping frame guide yarn hook, guide bar, retractable reed gear and so on.

A warping machine in our company has been seriously damaged due to its peel off from the electroplating layer of the tension plate, resulting in a high breakage of the sizing yarn, a severe breakage of the fabric, and a serious opening.

Therefore, we should promptly replace the defective menopause pieces and other parts in the circuit inspection, and make regular replacement for the production of pure polyester machines.

The relative humidity is controlled by standard and the experience value is 58% to 65%.

The value of the lathe operator meets the requirements of inspection according to the operation method, requiring the production site to be well cleaned, all parts of the bobbin frame, and no belly flowers.

In addition, increasing yarn strength and reducing hairiness by sizing is particularly important for fine size and high density varieties, which are easy to produce two hairiness due to rip, and increase the broken ends and directly affect the quality of the weaving shaft.

Sizing quality is directly related to sizing process parameters, sizing formulation, equipment status, and lathe operation level.

The degree of equipment integrity is closely related to the quality of the slurry shaft, especially the key process components, such as pressure roller, sizing roller, gas path, drying cylinder, tension system, etc. the quality of the slurry shaft often fluctuates greatly due to equipment failure.

For example, the aging of the press roller, especially the micropore pressure roller, when the time is too long, the surface rubber aging and micropore blockage will cause the hardness to change, reduce the amount of slurry, or the knife marks are serious, and the wear marks on the surface of the roller can cause small sizing and uneven sizing.

Problems such as bad hairiness and poor sticking will affect the quality of the pulp shaft and produce many defects. It should be changed periodically (at present, the grinding period of each mill is mostly half a year, and our factory is 3 months), so as to maintain its good condition.

Generally speaking, when the grouting force is constant, the sizing speed is high, the size of the sizing roller is large, the pressing time of the sizing roller is short, the sizing rate is too large, the sizing is mainly, but the permeability is insufficient. When the yarn is divided, the yarn will be increased by Mao Yu due to the tear. When the speed is too small, the yarn size will be less, the pressing time will be longer, the sizing rate will be small, the sizing penetration is insufficient, and Mao Yu will not be effectively stuck, and the number of Mao Yu will still be very high.

Therefore, the sizing speed should be reasonably set according to the varieties of warp, slurry composition, slurry viscosity, drying temperature and so on, so as to avoid low and excessive vehicle speed, reasonably control the degree of penetration and control the yarn hairiness in a reasonable range.

The pulping force is beneficial to the plume of 3mm and above, but it is unfavorable to the short feather feather of 2mm. This is because the stiffness of the short hair feather is larger than the long feather feather, and the feather is not easy to lodge, and the coating layer of the sizing is thinner and the holding force is not enough for the short hair feather.

As we all know, technology is the core, operation is the key, equipment is the foundation, and reduction is the foundation.

It is necessary to improve the quality of the weaving shaft. But we should excavate and give full play to the basic role of the equipment in the process research and operation innovation, and constantly adapt to the needs of variety development through technological pformation and management maintenance.

In equipment management, besides careful implementation of the flat car system, attention should also be paid to routine inspection and maintenance. For key process components such as sizing rolls, periodic grinding or replacement should be carried out to ensure that the equipment is in good condition, which is the key to achieving technological goals and stabilizing product quality.
