What Is The Fabric Of The Non-woven Fabric?
Aug 14, 2018

Textiles made from textile fibers by bonding, fusion or other chemical or mechanical methods. This kind of textile is not a traditional spinning, weaving or knitting process, also called non-woven fabric, non-woven fabric. Non-woven fabrics have been industrially produced since the 1940s and have developed rapidly due to high output, low cost and wide range of applications. Non-woven fabrics are divided into two categories: thin and thick. The thin weight is generally 20-100 g/m (used as a garment lining decorative cloth, handkerchief, feminine hygiene products, etc.; thick type used as flakes, carpets, filter materials, geotextiles (road fabrics), etc., can also be used Made of materials for special purposes such as heat insulation, ventilation, heat resistance, abrasion resistance, sound insulation, shock resistance, anti-virus, radiation protection, etc. The production technology of non-woven fabrics originated from papermaking and felting. The early non-woven fabrics were made of waste cotton or The textile scraps are processed and pressed to be used as low-grade batt or thermal insulation materials. After the 1950s, chemical fibers have been greatly developed, and non-woven fabric production techniques have also been improved. Techniques such as acupuncture, tufting and stitching have been adopted. The production of natural fiber and chemical fiber non-woven fabrics has been greatly increased, and the use has become increasingly widespread. The manufacturing methods of non-woven fabrics are divided into dry and wet methods.

What is the fabric of the non-woven fabric?

Dry method Firstly, the fiber raw material is opened, mixed and combed on a cotton spinning or wool spinning device to form a fiber web, and then a non-woven fabric is prepared by bonding into a cloth, mechanically forming a cloth or spinning into a cloth.

Fiber-forming webs There are methods such as parallel web formation, staggered web formation, and airflow web formation. Parallel-laid webs of 1 to 2 carding machines are repeatedly stacked in parallel to form a fiber web in which the fibers are longitudinally aligned. The nonwoven fabric made of such a fiber web has high longitudinal strength and low lateral strength. Interlaced into a web is a web in which the web output from the carding machine is folded into a certain number of layers through a curtain curtain, and the fibers are substantially horizontally aligned. Air-laid is a method in which the carded single fiber is agglomerated on the output mesh belt to form a fiber web. Due to the irregular arrangement of the fibers, the longitudinal and transverse breaking strength of the obtained nonwoven fabric is substantially the same. In addition, the carded fibers can be laid down into a quantitative fiber batt which is drawn into a web by pairs of serrated rolls and the fibers are randomly arranged in the flakes.
