What is the combination of non-woven and PE film?
Hot melt adhesive coating equipment applications and therefore continue to expand, medical and health materials production sector is the most widely used industries such equipment, the rapid development of the automobile industry in China also stimulated the spare parts manufacturers to hot melt adhesive coating The demand for cloth equipment, the relevant information shows that the domestic geotextile industry has recently introduced the first hot melt production line so far.As a mature and continuous development of the process, hot melt coating technology in the non-woven The prospects for the deep processing industry will be getting better and better.
Cloth powder composite: in the non-woven or film evenly sprinkle hot melt adhesive powder, and then through the heat of a composite method. Features: thermal pressure roller rubber roller and smooth roller on the material damage is very small. Disadvantages: the production rate is slow, low production efficiency; hot melt powder sprinkling evenly is the key to good or bad product quality, but the hot melt powder easy to absorb moisture evenly spread the fabric becomes very difficult, sprinkle volume is not good The melting temperature of the hot-melt adhesive powder is higher and the melting temperature of the breathable film is lower, and the hot-melt powder can not be completely melted at the time of composite, so that the peel strength is not enough and the surface roughness of the composite film is not good.
Hot Rolling: It is a standard process for the production of composite nonwovens by two-step method. Some domestic enterprises use this process for the manufacture of film and cloth. Features: You can use ready-made equipment and technology Disadvantages: The composition of the film is PE, and The composition of the non-woven fabric is polypropylene, the melting point of the two different hot roll can not take into account the temperature; hot roll heat capacity problems at the same temperature at different production rates lead to poor product compound strength uniformity; Accuracy is also a factor affecting the quality of the product; hot-rolled method for the breathable film material permeability loss rate (between 30-40%); production speed is slow.
With the disposable medical supplies (such as surgical clothing, surgical sheets, holes, gloves, shoes, hats, etc.), industrial protection products, personal care products mainly non-woven composite film products, these industries for the product Requirements are almost the same, that is waterproof, breathable and comfortable.
With the non-woven processing of raw materials mature, more and more enterprises will turn their attention to the deep processing of non-woven fabrics, as far as possible so that the value-added products and corporate profits can be improved.
