Description

Punching cotton and composite fabric thereof

The technical field is as follows:

the utility model belongs to the technical field of fabrics and non-woven fabrics, concretely relates to well cotton and compound surface fabric punch a hole.

Background art:

with the development of society and economy, people put higher demands on the functionality, comfort and aesthetic appearance of clothes, home textiles, sleeping bags, warm shoes, cushions and the like. For these products with the function of keeping warm, not only the products are required to have elegant appearance and excellent warm-keeping performance, but also the products are required to have the functions of portability, ventilation, comfort, portability and the like when being worn and used. Medium cotton is known as batting and is also known as viscose, non-viscose, water-washed, melt-blown, bicomponent, etc. They can be made by a number of different nonwoven processing techniques. For example, the fibers are carded by a carding machine to form a web, and the formed medium cotton is bonded by oven hot air or hot pressing or by using an adhesive, and also the medium cotton is formed by a needle machine after the fibers are formed into a web, and also the medium cotton is formed by a fiber nonwoven air-laying technique, and resin chips and fibers are melt-blown to form the web. These different types of medium cotton all form the three-dimensional structure of the fibrous material, with a certain thickness to give the material the ability to keep warm.
