The non-woven fabric has no warp and weft threads, it is very convenient to cut and sew, and it is light and easy to shape, which is deeply loved by craftsmen.
Because it is a kind of fabric that does not need to be spun and weaves, it just oriented or randomly arrange the textile short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods.
It is not made of interwoven and knitted yarns one by one, but the fibers are directly bonded together by physical methods. Therefore, when you get the sticky scale in your clothes, you will find that, It is impossible to draw a single thread. Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production rate, high output, low cost, wide use, and multiple sources of raw materials.
1. Physical properties: PP polypropylene anti-adhesive non-woven fabric is a non-toxic, odorless, milky white highly crystalline polymer with good formability. However, due to the large shrinkage rate, the original wall products are easy to dent, the surface of the products has good gloss and is easy to color.
2. Mechanical properties: PP polypropylene anti-adhesive non-woven fabric has high crystallinity, regular structure, and its strength, hardness and elasticity are higher than high-density PE (HDPE).
3. Thermal performance: PP polypropylene anti-adhesive non-woven fabric has good heat resistance, and the product can be sterilized at a temperature above 100 ℃. No deformation at 150°C under no external force. The embrittlement temperature is -35℃, embrittlement will occur below -35℃, and the heat resistance is not as good as PE.
4. Chemical stability: PP polypropylene anti-adhesive non-woven fabric has good chemical stability. In addition to being corroded by acid, it is relatively stable to other chemical reagents. PP polypropylene anti-adhesive non-woven fabric is suitable for making Russian-Chinese chemical pipelines. And accessories, good anti-corrosion effect.
5. Electrical properties: Non-woven fabrics have excellent high-frequency insulation properties and can be used to make heated electrical insulation products. The breakdown voltage is also high, and it is suitable for electrical accessories. Good resistance to voltage and arc, but high static electricity, easy to aging in contact with copper.
6. Weather resistance: Non-woven fabrics are very sensitive to ultraviolet rays. Adding zinc oxide thiopropionate dilaurin, carbon black-like milky white fillers, etc. can improve its aging resistance.
