What do you know about hot air non woven fabrics?
Nov , 12 2020
Hot air non woven fabric belongs to a kind of hot-air bonded (hot-rolled, hot-air) non woven fabric. Hot-air non woven fabric is a kind of non woven fabric which is formed by hot-air bonding after the fiber is combed and penetrated by the hot-air drying equipment.

ES fiber is an ideal thermal bonding fiber, which is mainly used for non-woven fabric thermal bonding processing. When the carded fiber web is thermally bonded by hot-rolling or hot-air penetration, the low-melting component forms a fusion bond at the intersection of the fibers, and after cooling, the fibers at the non-intersecting points remain in their original state. It is a form of "point bonding" instead of "zone bonding", so the product has the characteristics of bulkiness, flexibility, high strength, oil absorption, blood absorption and so on. In recent years, the rapid development of the application of thermal bonding method depends entirely on these new synthetic fiber materials.

The ES fiber and the PP fiber are mixed and then subjected to thermal bonding or needle punching treatment, so that the ES fibers are cross-linked and bonded. This method has the advantage that no adhesive and backing cloth are required.

Hot air adhesive products have the characteristics of high bulkiness, good elasticity, soft hand feeling, strong warmth retention, good air and water permeability, but their strength is low and they are easy to deform. With the development of the market, hot-air adhesive products are widely used in the manufacture of disposable products with their unique style, such as baby diapers, adult incontinence pads, feminine hygiene products, napkins, bath towels, disposable tablecloths, etc.; Type products are used to make cold-proof clothing, bedding, baby sleeping bags, mattresses, sofa cushions, etc. High-density hot melt adhesive products can be used to make filter materials, sound insulation materials, shock absorption materials, etc.
