Air through non woven fabric is a kind of hot air bonding (hot rolling, hot air) non woven fabric. Hot air non woven is to use the hot air on the drying equipment to penetrate the fiber web after the fibers are combed, so that they are heated and dried. The resulting non-woven fabric can be bonded.
ES fiber is an ideal thermal bonding fiber, which is mainly used for non woven thermal bonding process. When the carded fiber web is thermally bonded by hot rolling or hot air through, the low-melting component forms fusion bonds at the intersections of the fibers, and after cooling, the fibers at the non-intersections remain in their original state. It is a form of "point bonding" rather than "area bonding", so the product has the characteristics of bulkiness, softness, high strength, oil absorption, blood absorption and so on. In recent years, the rapid development of thermal bonding applications is entirely dependent on these new synthetic fiber materials.
ES fibers are mixed with PP fibers and then heat-bonded or needle-punched to make ES fibers cross-linked and bonded to each other. This method has the advantage of not using adhesives and backing cloth.
Hot air bonding products have the characteristics of high bulkiness, good elasticity, soft hand feeling, strong warmth retention, good air permeability and water permeability, etc., but their strength is low and 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, fabrics for feminine hygiene products, as well as napkins, bath towels, disposable tablecloths, etc.; thick Type products are used to make cold 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.
