What are the ingredients of the popular Nonwoven Fabrics
Nonwoven Fabrics are now mainly used in industrial, medical work clothes. Its anti-bacterial, breathable, environmentally friendly features also received the majority of customers of all ages. Here we come to introduce the composition of Nonwoven Fabrics are what components.
Nonwoven Fabrics ingredients, the exact name of Nonwoven Fabrics should be Nonwoven Fabrics. Because it is a need to spun the fabric and the formation of the fabric, but the textile short fiber or filament orientation or random support, the formation of fiber structure, and then use mechanical, thermal or chemical methods such as reinforcement. Nonwovens break through the traditional textile principles, and has a short process, production speed, high yield, low cost, wide use, raw materials and more features.
The main purpose of Nonwoven Fabrics can be divided into: (1) medical and health cloth: surgical clothing, protective clothing, disinfection cloth, masks, diapers, sanitary napkins, etc .; (2) home decoration cloth: (4) industrial fabrics: filter materials, insulating materials, cement bags, and so on. (4) industrial fabrics: filter materials, insulating materials, cement bags (6) Other: space cotton, insulation materials, oil-absorbing felt, smoke filter, bag, bag, cloth, Bag tea bags and so on.
The three fibers used in the production of nonwovens are polypropylene (62% of the total), polyester (24% of the total) and viscose (8% of the total). In the period from 1970 to 1985, the application of viscose fiber in production was the most. In the last five years, the application of polypropylene fiber and polyester fiber was dominant in the field of sanitary absorbent materials and pharmaceutical textiles. In the early production market, the amount of nylon used very large, since 1998, the amount of acrylic fiber began to rise, especially in the field of artificial leather manufacturing.
Editors according to most of the Nonwoven Fabrics does not require pretreatment can be coated, but some of the base fabric must be prepared before the coating process. Nonwovens, such as nylon and polyester fibers, can often be coated directly for use as an outdoor protective canopy, but when used under certain conditions, the coating must be washed and heat set.
At present, there are many kinds of methods and equipment for coating nonwovens. Choose what kind of processing methods or equipment to a large extent based on the final use of fabric and requirements, but also take into account the characteristics of coating agents and Nonwoven Fabrics of the physical and mechanical properties, of course, also consider the process Of the economy. Due to the different coating methods can produce different shear force on the coating agent, presses on the Nonwoven Fabrics also have different penetration, so the choice of coating method will affect the appearance of the coating, thickness, bonding Strength and optical properties.
The industry said that Nonwoven Fabrics coating technology has been simply can not be seen as a fabric finishing technology, polymer coating film can be regarded as a space, it can accommodate many substances, will make the fabric with finishing technology The special performance and function. Coating products in recent years has developed very rapidly, both in the fabric or decorative and industrial industries with textiles have a new breakthrough, and the future coating technology in the development of functional fabrics will be much better.
In this paper, we selected five enterprises with different coating processes, analyzed their problems in the actual production process and improved methods for other similar enterprises to provide some reference to the improvement of production.
