Introduce the cleaning process of non-woven equipment

Environmental protection is the theme advocated in the 21st century. The production and use of non-woven fabrics are in line with the theme of green environmental protection. As the use of non-woven fabrics becomes more and more widespread, the use of non-woven equipment and the market are put on the agenda. Talk about the technological process of non-woven equipment and some general issues that should be paid attention to when cleaning!

The raw materials used in the production of non-woven fabrics include cotton fiber, cotton-type chemical fiber and medium-length chemical fiber, and its products include pure cotton yarn, purified fiber yarn and various types of blended yarn.

1. Carding system The fiber length processed by the carding system is between 25 -40mm and the linear density is 1.3-1. 7dex. It is generally used for spinning medium and high special yarns for weaving ordinary fabrics.

2. Fine mirror system The combing system is used to spin high-grade cotton yarn, special yarn or cotton and chemical fiber stick spinning. For spinning ultra-low special yarns below 7.3 tex, long-staple cotton with a length of 37mm or more and a linear density of 1.2 dtex is required for raw cotton.

When processing cotton, the pre-combing preparation and combing procedures are added after carding. The purpose is to remove short fibers and fine impurities below a certain length, and further straighten and parallel fibers, so that the yarn structure is more uniform, smooth and strong. The raw material of the non-woven equipment is high-quality fine-staple cotton or long-staple cotton. When cotton is blended with chemical fiber, the chemical fiber adopts the blowing-carding process, and the chemical fiber sliver is directly mixed with the cotton sliver on the draw frame.

When the non-woven equipment is cleaned and combed, some fibers will accumulate between the smooth side of the non-woven equipment and the inner surface of the casing relative to it, thereby forming cotton tufts or cotton masses. These cotton tufts or cotton masses are often caught in the spinning cup during operation, and cause kinks or break ends on the yarn. The vortex comb of air is the main cause of fiber accumulation. The airflow speed in the non-woven fabric channel is about 100 m/s, and the surface speed of the non-woven fabric equipment is generally 10% faster. When the spinning speed is about 30,000 rpm, the surface of the condensed grain is close to 100 meters per second.
