The difference between PET nonwoven fabric and PP nonwoven fabric
Polyester (PET) non-woven What is it? Polyester (PET) non-woven fabrics and PP non-woven difference;
Polyester (PET) non-woven spunbond non-woven fabrics is a kind of non-woven, its raw material is 100% polyester chips. It consists of numerous endless filaments through the spunbond hot-rolled. Also known as PET spunbond non-woven fabric or PES spunbond non-woven, also known as single-component spunbond non- woven fabrics.
PET non-woven features
First, polyester (PET) spunbond non-woven fabric is a water-repellent non-woven fabric, depending on the weight of the different non-woven water repellency is also different. The heavier, heavier, the better the water repellency. If there is water droplets on the surface of the non-woven fabric, the water drops will slide off the surface directly.
Second, high temperature. Due to the melting point of polyester at about 260 ° C, the temperature stability in the environment, you can maintain the stability of non-woven fabric dimensions. Has been widely used in heat transfer printing, transmission oil filtration, and some require high temperature composite materials.
Third, polyester (PET) spunbond non-woven is second only to nylon spunbond non-woven fabric of a filament non-woven. Its excellent strength, good breath-ability, tensile tear resistance and anti-aging properties have been applied by more and more people in various fields.
Fourth, polyester (PET) spunbond nonwovens also have a very special physical properties: anti-gamma rays. That is, if applied to medical products, gamma rays can be sterilized directly without compromising the stability of their physical properties and size, which is not found in the physical properties of PP spunbond fabrics.
PP non-woven and PET non-woven fabric difference
PP is a polypropylene raw material, that is, polypropylene fiber, is a thin non-woven; PET is a new polyester raw material, that is, polyester fiber, the entire production process without any additives, is a very good environmentally friendly products, are thick non-woven fabrics.
(PP) polypropylene non-woven with (PET) polyester non-woven comparison:
1, PP cheap raw materials, PET raw materials expensive. PP waste can be recycled, PET can not be recycled, so the PP cost is slightly lower.
2, PP high temperature at about 200 degrees, while PET at about 290 degrees, PET is more than PP high temperature.
3.non woven printing,heat transfer effect,the same width PP contraction,PET shrinkage,the effect is better,PET is more economical and less waste.
4, Rally, tension, load-bearing capacity, the same weight, PET tensile than PP, tension, bearing capacity. 65 grams of PET is equivalent to 80 grams of PP tension, tension, load-bearing.
5, environmental point of view, PP due to reflow PP refuse, PET all new polyester chips, PET more environmentally friendly than PP more hygienic.
PET nonwovens a wide range of applications
① Home Textiles: anti-velvet lining, thermal transfer printing, non-woven calendars, office documents hanging bags, curtains, vacuum cleaner bags, disposable garbage bags.
② packaging: cable cloth, handbags, container bags, packet materials, desiccant, adsorbent packaging materials.
③ decoration: wall decoration fabric, leather floor fabric, flocking fabric.
④ agriculture: agricultural harvest cloth, crop and plant protection, weed protection tape, fruit bags and so on.
⑤ waterproof material: high-grade breathable (wet) waterproof fabric fabric.
⑥ industrial applications: filter materials, insulating materials, electrical appliances, reinforcing materials, supporting materials.
⑦ other: protective equipment, tourism products.
⑧ filter: transmission oil filter.
