There are many types of felt pads on the market today, and the quality is uneven, so when choosing, you must pay great attention to ensure that you can buy a very good felt pad.
Synthetic wool felt is a wool felt, a lot of use, chemical fiber felt is a kind of high quality felt type. The usual chemical fiber felts are made of polyester, polypropylene, acrylic, imported fiber, etc. as raw materials. And chemical fiber wool felt more used in garment factories, bag factory. In the use of chemical fiber felt compared with ordinary felt what are the advantages?
High strength Because of its hygroscopicity, his humidity and dryness are basically the same. High impact strength 4 times higher than nylon, viscose fiber 20 times higher.
Good elasticity Elastic close to the wool, when the elongation of 5% to 6%, almost completely restored. Wrinkle resistance than other fibers, the fabric is not this week, good dimensional stability.
3 good heat resistance.
Good wear resistance. Second only to the wear resistance of the best nylon grinding, better than other natural fibers and synthetic fibers.
5. Good light resistance. Lightfastness second only to acrylic.
6. Corrosion resistance. Can be resistant to bleach, oxidants, ketones, petroleum products and inorganic acids.
Felt material is pure natural wool, the most direct way is to distinguish, that is, from the felt rubbing some wool, with the point of burning wool wool burning in the process of burning and accompanied by blistering, burned things burning hair taste. After the incineration of the ash is a black crisp, no coke. From the appearance of investigation, pure felt feel soft, flexible, fine lines have rules. Relatively speaking, chemical fiber felt is made of wool and synthetic fiber, the price is lower than pure felt. The performance of both pure wool insulation, soft and other characteristics. Chemical fiber felt can also use the taste of burning and ash to distinguish the proportion of its material, from the touch on the distinguished can not afford static electricity for the top grade
