What is PP Spunbond Nonwoven Fabric?
Non woven fabric is fabric that does not need to be woven. It is a fabric made of short fibers or filaments that are naturally arranged into a whole through a special manufacturing process, and is also called non woven fabric. It is air-permeable, light-permeable, moisture-proof, mildew-proof, durable, and environmentally friendly. It is widely used in many areas of society. PP non woven fabric is a non woven fabric made of polypropylene. There are many non-woven fabrics, and pp non woven fabrics are equally versatile and are used in many areas of society!
The production process of pp non woven fabrics generally includes melting, spinning, etc. The production process is not complicated, relatively simple, low production cost, low price, of course, because there are still many brands of pp non woven fabrics, the price is still very different, and some productions The process is cumbersome, the technical requirements are high, and the cost is high. In addition, the geographical location of the manufacturer is different in the consumption environment, and the profit pursued by the manufacturer is different, which leads to the difference in the price of this kind of non-clothing. This pp non woven fabric has a wide range of uses in medical and health, printing, packaging, clothing, automobiles, agriculture and other fields, and the variety of patterns and colors is amazing.
The patterns and colors of pp non woven fabrics can be fashionable and bright, classic and solemn, playful and lively, etc. In short, it can meet various purposes, Such as use in aerospace, building materials, etc. In agriculture, it can be used as a cover film on greenhouses, fruit plants, etc., for heat preservation, frost prevention, insect prevention, sun protection, etc. It can be used as a variety of interlinings on clothing.
Because this kind of non woven fabric is environmentally friendly and has a short degradation time, it is widely used in agriculture. After being used up, it is placed in the ground to let it weather and be absorbed by nature. It takes at least 300 years for ordinary plastic products to degrade.
The difference between S and SS nonwoven fabric:
● S spunbonded non-woven fabric is a thermal bonding single-layer web;
SS non-woven fabric is made thermal bonding of two layers of fiber mesh. The finished product is non-toxic and tasteless, and has high-efficiency isolation. Through special treatment of equipment and technology, it can achieve antistatic, anti-alcohol, anti-plasma, and water-repellent properties.
● Under normal circumstances, S and SS can be distinguished by softness.
S non-woven fabrics are mostly used in the packaging field, and SS non-woven fabrics are mostly used in sanitary materials. Therefore, in the mechanical design, the S machine tends to make the non-woven fabric stiffer, and the SS machine tends to make the non-woven fabric softer.
However, after a special process, S non-woven fabric has a softer feel than untreated SS fabric, which is suitable for sanitary materials; and SS can also be treated to become more rigid and suitable for packaging materials.
Another distinguishing latitude is the uniformity of the cloth, which refers to the stability of the weight per square meter, but it is difficult to distinguish by the naked eye.
● In essence, the difference between S and SS non-woven fabrics lies is the number of nozzles in the machine. The number of letters in the name represents the number of nozzles, so S has one nozzle and SS has two nozzles.
SS non-woven fabric is softer than other non-woven products.
All products made of fine fibers have strong air permeability, which can keep the fabric dry and easier to clean. This is a non-irritating, non-toxic product that meets the requirements of food-grade raw materials, and the fabric without any chemical substances is harmless to the body.
