Chapter TPU ring rolling

As an auxiliary material, the market competition of polyester fiber ribbon industry is becoming more and more fierce, the main strategy at present is to seek the development of differentiation, that is, the so-called innovation, most of the current polyester ribbon industry is heavy style light quality. But this is not desirable, must control the key quality issues, in the pursuit of style diversity.

The reason why ribbon manufacturers from the source to build the brand strength of polyester ribbon, because the role of accessories not only requires good-looking, but also pay attention to comfort and health, nylon ribbon dye is a more complex organic material, it has a lot of kinds:

1, azo fuel (naftod dye), suitable for cellulose fabrics, bright color, more suitable for bright color.

2, reactive dyes, mostly used for cellulose fabrics, less used for protein. It is characterized by bright color, light resistance, washing and friction resistance.

3, sulfur dyes, suitable for cellulose fiber fabrics, dark color, mainly navy blue, black and brown, light resistance, water resistance is very good, poor chlorine bleaching, long-term storage fabric will damage the fiber.

4, disperse dyes, suitable for viscose, acrylic, nylon, polyester, etc., washing fastness is different, polyester is good, viscose is bad.

Observe the fabric edge: if the fabric edge is smooth, the neat side is the front of the fabric. Double, multi-ply and multi-ply fabrics with different warp and weft densities on the front and back are generally of greater density on the front or better raw materials on the front. Leno fabric: the face of the fabric with clear lines and prominent twists. Towel ribbon: the face with dense loops.

Polyvinyl formalin (pva) fiber, not easy to ignite, close to the flame melting shrinkage, burning the top of a little flame, until the fibers are melting into a gelatinous flame, there is thick black smoke, send out bitter smell, burning left black beads, can be crushed with your fingers.
