Ribbon raw materials(polyester ribbon) Polyester (PET) : 1, strong wear-resistant. 2, poor water absorption, the common moisture regain 0.4% (20 ℃, relative humidity 65%, 100g polyester water 0.4g). 3, easy to static, easy to pilling from the ball. 4, acid and alkali resistance. Note: a certain concentration of alkali at a certain temperature damage to the polyester surface makes the fabric feel soft. 5, corrosion resistance, light resistance is better. 6, polyester fiber woven fabric is not easy to wrinkle, good dimensional stability, easy to wash fast dry. Polyester spinning: 1, FDY (filament): single fiber parallel smooth and smooth, sub-bright, light, half-light, extinction, the brightness is getting weaker. 2, DTY (wire): single fiber bending, low stretch, fluffy, as shown. 3, DTY network wire (low elastic network wire): there are stages of the network point, increase the ability to bundle between the fiber capacity (sub-network, light network, network, heavy network, which can be...
