What is the difference between non-gel cotton and non-woven fabrics? Non – gel cotton is one of the non-woven fabrics. It is a high-grade material for padding, warmth retention, sound absorption and filtering materials. It has the characteristics of good air permeability, good warmth retention, light weight, strong resilience, aging resistance, water washing resistance and no mildew. It is a new type of material widely used at home and abroad and is also an updated product of spray gel cotton and sponge. It can be used for mattresses, cushions, tatami mats, sofa cushions, bras, quilts, sleeping bags, bedspreads, gloves, shoes, soft sound-absorbing materials, air filtering materials, roof insulation, wall insulation, car roof coverings, battery separators, etc. The non-woven fabrics are made of polypropylene The chemical molecular structure of polyethylene has very strong stability and is extremely difficult to degrade, so it will take 300 years for the plastic bag to decompose. However, the chemical structure of polypropylene is not firm, and the molecular chain can be easily broken, thus effectively degrading, and entering the next environmental cycle in a non-toxic form, a non-woven fabric product ( non – woven fabric bag ) can be completely decomposed within 90 days.
What kind of fabric is non-woven cloth? non woven fabric
non-woven fabric
Textiles made from textile fibers by bonding, fusing or other chemical or mechanical methods. This kind of textile does not go through the traditional spinning, weaving or knitting process, also known as non-woven fabrics and non-woven fabrics. Non – woven fabrics have been produced industrially since the 1940s, and have developed rapidly due to their high output, low cost and wide range of use. Non – woven fabrics fall into two categories: thin and thick. Thin weight is generally 20 ~ 100g / m (, used as clothing lining decorative cloth, handkerchiefs, women’s sanitary articles, etc.; Thick type used as wadding, carpet, filter material, geotextile ( roadbed cloth ), etc. It can also be used to make materials for special purposes such as heat insulation, ventilation, heat resistance, wear resistance, sound insulation, shock resistance, gas protection, radiation protection, etc. The production technology of non-woven cloth originated from papermaking and felting. The early non-woven cloth was made of waste cotton or textile mill leftovers after being treated and pressed as a low-grade batting pad or warm-keeping material. Since the 1950s, chemical fibers have developed greatly, and the production technology of non-woven fabrics has also been improved. Acupuncture, tufting, sewing and other technologies have been adopted one after another. The production of natural and chemical fiber non-woven fabrics has increased greatly and their uses have become increasingly widespread. The manufacturing methods of non-woven fabrics are divided into dry and wet methods.
In dry process, fiber raw materials are first opened, mixed and carded on cotton spinning or woolen spinning equipment to make a fiber web, and then non-woven cloth is made by bonding into cloth, mechanically forming cloth or spinning into cloth, etc.
There are several methods of fiber web forming, such as parallel web forming, staggered web forming and air flow web forming. The fiber webs output by 1 – 2 carding machines are overlapped in parallel for many times to form fiber webs with longitudinal arrangement of fibers. The non-woven cloth made of the fiber web has high longitudinal strength and low transverse strength. Interlacing is to fold the fiber web output by carding machine into a certain number of layers of fiber web through the laying curtain, and the fibers are basically horizontally arranged. Airflow forming is the process of forming a fiber web by aggregating carded single fibers on the output web with airflow. Due to the irregular arrangement of fibers, the vertical and horizontal breaking strength of the non-woven fabric is about the same. In addition, the combed fibers can also be laid and overlapped into quantitative fiber flocs, drawn into a net by pairs of sawtooth rollers, and the fibers are randomly arranged in the flocs.
