How to identify synthetic fiber felt?

　　 Synthetic fiber felt It is a high-quality felt type. Typically, the raw materials for synthetic fiber felts include polyester, polypropylene, acrylic fibers, and imported fibers. In addition, synthetic fiber felts are widely used in garment factories and packaging plants. What advantages does synthetic fiber felt offer compared to ordinary felt in practical applications?

　　How should we identify synthetic fiber felt?

　　Pure felt is made by bonding pure wool together. Synthetic fiber felt It is a blend of wool and synthetic fibers.

　　The raw material for felt is natural wool. A straightforward way to distinguish it is to rub some wool off the felt and then set it alight with a flame. During combustion, the wool produces smoke and bubbles, and the burning residue has a smell reminiscent of scorched hair. After burning, the ash is black and brittle, with no charred residue remaining.

　　From a superficial perspective, pure felt has a soft, elastic feel and a fine, uniform texture. In contrast, synthetic fiber felt is a blend of wool and synthetic fibers and is priced lower than pure felt. It retains the insulating and soft qualities characteristic of pure felt.

　　Chemical fiber felt can also be distinguished by the smell of burning and ash, which reflects the relative proportions of its raw materials, and can be differentiated from materials that cannot withstand static electricity.

　　When ordering synthetic fiber felt, simply provide the product number corresponding to the standard category designation specified by your department, along with the required specifications such as thickness, length, and width. If you require dyeing, please also specify your color preferences.

　　1 > The technical code for synthetic fiber felt consists of five digits: the first digit indicates the product’s color, the second digit indicates the classification of the materials used, the third digit indicates the specifications of the product type, and the fourth and fifth digits indicate the product’s density. The letter “t” denotes special felt.

　　2. When ordering felt wheels and felt products, you should specify the required product number based on the department’s standard category naming convention, and also provide detailed drawings of the parts. The allowable tolerances for part dimensions generally should comply with the department’s standards.

　　3 > If individual Synthetic fiber felt If the product has special requirements for certain technical conditions and specifications during use, these can be specified separately when placing an order, and the two parties can negotiate a solution.
