PET Spunbond Nonwoven Fabric Performance Classification

Yiwu Guanghong Non-Woven Co.,Ltd | Updated: Sep 28, 2017

What is the difference between the production process PET non-woven fabric and the PP non-woven fabric? Non-woven fabric of the exact name should be nonwoven fabric, nonwoven or call. Because it is a kind of don't need to be formed by spinning weaving fabric, just short textile fiber or filament for directional or random supporting columns, form a fiber network structure, and then we used mechanical, thermal or chemical methods such as solid. The characteristics of non-woven fabrics. Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process, fast production speed, high yield, low cost, wide use and many sources of raw materials.

What is the composition of PP nonwoven cloth?

The main ingredient is polypropylene, a good nonwoven fabric is the fusion of whole polypropylene. ~ but some non-woven fabrics will be added by the manufacturer of calcium carbonate, so the quality will be much worse, if you need to pay attention to the sanitary products!

The difference between pp nonwoven fabrics and pet non-woven fabrics

PP is polypropylene raw material, namely polypropylene fiber, PET is polyester raw material, namely dacron fiber

(PP) polyester nonwovens compared with (PET) proc nonwoven fabrics

1.PP raw materials are cheap, PET materials are expensive, and the waste of PP can be recycled. The non-return of PET, so the cost of the PP is slightly lower.

2. The high temperature of the PP is about 200 degrees, while PET is about 290 degrees, and PET is more resistant to heat than PP.

3. Non-woven printing, thermal transfer effect, the same width of PP shrinkage, PET to reduce PET effect better, PET more waste less waste.

4. Tension, tension, load bearing force, same weight, PET is stronger than PP, tension, bearing force. 65 grams of PET is equivalent to 80 g of PP pull, tension, load bearing force.

5. On the environmental side, PP is more environmentally friendly and hygienic than PP due to the doping of PP waste and all new PET slices.

PET polyester non-woven fabrics have a performance classification

The stability is better than the polypropylene nonwoven fabric

The main performance is: strong, wear-resisting and so on. Due to the special raw materials used in polyester non-woven fabrics, the technology of the advanced imported equipment and complicated and scientific processing technology has gone far beyond the technical content and requirements of the polypropylene nonwoven fabric.

Heat resistance is superior to that of polypropylene nonwoven fabric

Polypropylene non-woven fabric has the obvious thermal contraction, according to the survey, when the temperature reaches 140 ℃ has obvious shrinkage, and polyester fiber non-woven fabrics of the highest temperature can reach 230 ℃ or so, compared with the polypropylene non-woven fabric has distinct characteristics.

The anti-aging period is higher than the nonwovens of polypropylene

Polyester non - woven fabric is used as raw material, anti - worm, wear-resisting and ultraviolet ray, the above characteristics are all higher than the polypropylene nonwoven fabric.

Iv. Having good air permeability

The polyester non-woven fabric and polypropylene and other non-woven fabrics have the excellent performance of non-absorbent, water and air permeability.

The first is the difference in raw materials: PP refers to polypropylene, polypropylene; PET is dacron, that is, polyethylene diacetate.

Secondly, these two kinds of non-woven fabrics differ greatly in their application, but in some respects they can be replaced. It's just a difference in performance.

In addition, in the way of production and processing, these two have the same and different. Different processing methods determine the final application in most cases. In contrast, PET polyester non-woven fabrics are more expensive and more expensive.
