Brief analysis of hot air non-woven fabric

Hot-air non-woven fabric belongs to a kind of hot-air bonding (hot-rolled, hot-air) non-woven fabrics. Hot-air non-woven fabrics are used to penetrate the fiber web by hot air on drying equipment after the fiber is carded, so that it can be heated. Bonded non-woven fabric. 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-point components form a fusion bond at the intersection of the fibers. After cooling, the fibers at the non-intersections remain in their original state. It is a form of 'point bonding' instead of 'zone bondingIn 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.
