What are the differences between PP non-woven and polyester nonwoven fabrics

Polypropylene (PP) geotextiles are mainly woven geotextiles, nonwoven geotextiles, geomembrane, and composite geotextiles. The weaving geotextiles are also divided into woven geotextiles and woven geotextiles. The characteristics of polypropylene geotextiles are that 1- polypropylene woven geotextiles are produced on a shuttle loom or shuttle loom, rapier and other shuttleless looms. Polypropylene woven geotextiles are more suitable for strengthening and reinforcing functions. Therefore, woven geotextiles are generally used as separate, enhanced and controlled etching applications. 2- nonwoven geotextile nonwoven geotextiles are generally made on a continuous line. Polypropylene nonwoven geotextiles are mainly divided into 2 kinds, namely, spunbond and short fiber needling according to the production process. And Dacron geotextile is a kind of nonwoven and industrial fabric. A polyester staple fiber with a fiber size of 6-12 and a length of 54-64mm is used as the raw material. Through the loosening of non-woven production equipment, the process of making the mess (short fibers intertwined together), laying nets (specification entanglement fixation), needling and other production processes is made into cloth.

It is straightforward to say that polypropylene fiber is relatively white, polypropylene fiber is smaller than polyester fiber density, polypropylene fiber is acid and alkali resistant, aging resistant, polyester is aging resistant, and is not resistant to acid and alkali.

First of all, from the raw material, the melting point of the two products is different. The PET is at more than 250 degrees, while the PP is only 150 degrees. If you need oven or heating temperature above 150 degrees, you can only use PET.

The first is the difference of raw materials: PP refers to polypropylene, namely polypropylene; PET is polyester, namely poly phenylene ethylene ester of oxalic acid two. Secondly, the two kinds of non-woven fabrics have great differences in application, but in some ways they can be replaced by each other. It's just a difference in performance. In addition, there are similarities and differences between the two types of production and processing. Different processing methods determine the final application in most cases. In contrast, PET is a bit more expensive and more expensive. PET polyester non-woven fabric has: one, the stability is better than polypropylene non-woven fabric mainly in: strength, wear resistance and other properties. The polyester non-woven fabrics with special raw materials, after processing thus imported advanced equipment and sophisticated and scientific, has gone beyond the technical content and requirements of polypropylene non woven fabrics. Two, heat resistance is better than polypropylene, non-woven, polypropylene and non-woven fabrics with obvious thermal shrinkage. According to the investigation, when the temperature reaches 140 degrees, there is obvious shrinkage, and the highest temperature of polyester nonwovens can reach 230 degrees, which has obvious characteristics compared with polypropylene non-woven fabrics. Three, the anti aging period is higher than that of polypropylene, non-woven fabric, polyester non-woven fabric, polyester is used as raw material, insect resistant, wearable and UV resistant, all of which are higher than those of polypropylene non-woven fabrics. Four, good air permeability polyester nonwovens and polypropylene and other non-woven fabrics compared with no water absorption, water is not allowed, strong permeability and other excellent properties.
