Polyester (PET)What is a non-woven fabric? Polyester (PET)The difference between non-woven fabric and PP non-woven fabric; Polyester (PET) Spunbonded filament non-woven fabric is a kind of non-woven fabric. Its raw material is 100% polyester slices. It is made up of countless continuous polyester filaments through spunbond hot rolling. Also called PET spunbonded filament non-woven fabric or PES spunbonded non-woven fabric, also called single-component spunbonded non-woven fabric. PET non-woven fabric features, first, polyester (PET) Spunbonded filament non-woven fabric is a kind of non-water-resistant non-woven fabric. The non-woven fabric has different water-resistant properties according to the weight of the gram. The larger and thicker the weight, the better the water resistance. If there is water droplets on the surface of the non-woven fabric, the water droplets will slide directly from the surface. Second, high temperature resistance. Because the melting point of polyester is about 260 °C, the stability of the external dimensions of non-woven fabrics can be maintained in an environment requiring temperature resistance. It has been widely used in thermal transfer printing, transmission oil filtration, and some composite materials that require high temperature resistance. Third, polyester (PET) Spunbonded non-woven fabric is a filament non-woven fabric after nylon spunbonded non-woven fabric. Its excellent strength, good air permeability, tensile tear resistance and anti-aging performance have been applied to more and more people in various fields. Fourth, polyester (PET) Spunbonded non-woven fabrics also have a very special physical property: Anti-gamma rays. That is to say, if it is applied to medical products, it can be directly disinfected with gamma rays without destroying its physical properties and dimensional stability. This is polypropylene (PP)Spunbonded non-woven fabrics do not have physical properties. The difference between PP non-woven fabric and PET non-woven fabric PP is polypropylene raw material, namely polypropylene fiber, which belongs to thin non-woven fabric; PET is a brand-new polyester raw material, I . e. polyester fiber. It has no additives in the whole production process. It is a very good environmental protection product and belongs to thick non-woven fabric. (PP)Polypropylene non-woven fabric heel (PET) Comparison of polyester non-woven fabrics: 1. PP raw materials are cheap and PET raw materials are expensive. The waste of PP can be recycled and PET cannot be recycled, so the cost of PP is slightly lower. 2. PP has a high temperature resistance of about 200 degrees, while PET has a temperature resistance of about 290 degrees. PET is more resistant than PP. 3, non-woven printing, thermal transfer effect, the same width PP shrinkage is large, PET shrinkage is small, the effect is better, PET is more economical and less wasteful. 4, tension, tension, bearing capacity, the same gram weight, PET is larger than PP tension, tension, bearing capacity. 65 grams of PET is equivalent to the tension, tension and bearing capacity of 80 grams of PP. 5. From the perspective of environmental protection, PP is doped with PP waste and PET is completely new polyester chips. PET is more environmentally friendly and sanitary than PP. PET non-woven fabrics are widely used in home textiles: Anti-velvet lining, heat transfer printing, non-woven calendar, office document hanging bags, curtains, dust bag, disposable garbage bags. (2) packaging: Cable cloth, handbag, container bag, flower material, desiccant and adsorbent packaging material. (3) decoration: wall decoration cloth, floor leather base cloth and flocking base cloth. 4 Agriculture: agricultural harvest cloth, crop and plant protection, weed protection belt, fruit bag, etc. ⑤ Waterproof material: high-grade breathable (Wet)Waterproof base cloth. Industrial application: filter materials, insulation materials, electrical appliances, reinforcement materials and support materials. ⑦ Others: protective equipment, travel products, etc. ◇ Filtration: filtration of transmission oil.
