Polypropylene (PP) geotextile mainly includes woven geotextile, non-woven geotextile, geomembrane, and composite geotextile. Among them, woven geotextiles are divided into woven geotextiles and woven geotextiles.

The characteristics of polypropylene geotextile are:

1. Polypropylene woven geotextiles are all produced on wide shuttle looms or shuttleless looms such as projectiles and rapiers. Polypropylene woven geotextile is more suitable for the function of strengthening and strengthening, so when it is used for separation, reinforcement, and erosion control applications, generally woven geotextile can be used.

2. Non-woven polypropylene geotextile Non-woven geotextile is generally made on a continuous production line. According to the production process, polypropylene non-woven geotextiles are mainly divided into two types: spunbond method and short fiber needle punch method.

The polyester geotextile is a kind of non-woven and industrial fabrics. It uses polyester crimped staple fiber with a fiber denier of 6-12 denier and a length of 54-64mm as raw materials. Through the process of opening, laying, and needle punching of non-woven production equipment, it is made into cloth.

To be more straightforward, polypropylene fiber is whiter, polypropylene fiber has a lower density than polyester fiber, polypropylene fiber is resistant to acid and alkali, and polyester is resistant to aging and acid and alkali.

First of all, in terms of raw materials, the melting points of the two products are different. PET is more than 250 degrees, while PP is only 150 degrees. If you need to use an oven or the heating temperature is above 150 degrees for your back-end process, only Can use PET.

The first is the difference in raw materials: PP refers to polypropylene, which is polypropylene; PET refers to polyester, which is polyethylene terephthalate. Secondly, these two types of non-woven fabrics are quite different in application, but they can be substituted for each other in some aspects. 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. Relatively speaking, PET is more high-end and more expensive.

PET polyester non-woven fabric has:

1. Stability is better than polypropylene non-woven fabric

Mainly manifested in: strength, wear resistance and other properties. Because polyester non-woven fabrics use special raw materials, they are produced by advanced imported equipment and complex and scientific processing techniques, which far exceed the technical content and requirements of polypropylene non-woven fabrics.

2. Heat resistance is better than polypropylene non-woven fabric

Polypropylene non-woven fabric has obvious thermal shrinkage. According to investigation, there will be significant shrinkage when the temperature reaches 140C, while the highest temperature of polyester non-woven fabric can reach about 230C, which has obvious characteristics compared with polypropylene non-woven fabric.

3. Anti-aging cycle is higher than polypropylene non-woven fabric

Polyester non-woven fabric is made of polyester, which is resistant to insects, abrasion and ultraviolet rays. The above characteristics are higher than polypropylene non-woven fabric.

4. Has good air permeability

Compared with polypropylene and other non-woven fabrics, polyester non-woven fabrics have excellent properties such as non-absorbent, incompatible with water, and strong air permeability.

The difference between pp non-woven fabric and pet non-woven fabric

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

(PP) Polyester non-woven fabric and (PET) acrylic non-woven fabric comparison

1. The raw materials are cheap, the PET raw materials are expensive, and the waste of PP can be recycled. PET is not reflowable, so the cost of PP is slightly lower. High temperature resistance is about 200 degrees, while PET is about 290 degrees. PET is more resistant to high temperature than PP.

3. Non-woven fabric printing, heat transfer effect, the same width PP shrinks large, PET shrinks small PET effect is better, PET is more economical and wasteful.

4. Tension, tension, bearing capacity, the same weight, PET is larger than PP tension, tension, and bearing capacity. 65 grams of PET is equivalent to 80 grams of PP tensile force, tension, bearing capacity.

5. From the perspective of environmental protection, PP is mixed with recycled PP waste, and PET is all new polyester chips. PET is more environmentally friendly and sanitary than PP.

The advantages of PET non-woven fabric over PP non-woven fabric are:

The cloth has good coverage, soft hand feeling and high strength, especially in terms of thermal stability, temperature resistance, UV resistance, aging resistance, dyeability and uniformity.
