Product Description
The main physical and chemical properties of Nylon DTY twisting
The longitudinal surface of Nylon is straight and smooth, with a circular cross-section. Nylon is alkali resistant but not acid resistant. In inorganic acids, the amide bonds on Nylon macromolecules will break.
Nylon has high strength, large elongation, and excellent elasticity due to its strong stretch ability and wear resistance. Its fracture strength is about 42-56cN/tex, and its fracture elongation reaches 25% -65%. Therefore, Nylon has excellent wear resistance and ranks first among common textile fibers. It is an ideal material for making wear-resistant wiping products. But Nylon has a small initial modulus, is prone to deformation, and its fabric is not stiff.
Moisture absorption and dyeing properties Nylon has good moisture absorption among common synthetic fibers, with a moisture regain of about 4.5% under general atmospheric conditions. In addition, Nylon has good dyeing properties and can be dyed with acid dyes, dispersed dyes, and other dyes.
Due to the sensitivity of the end groups of Nylon macromolecules to light and heat, Nylon turns yellow and becomes brittle. Therefore, Nylon has poor light and heat resistance and is not suitable for making outdoor fabrics. In addition, Nylon is corrosion-resistant, not afraid of mold, and not afraid of insect infestation. Nylon twisted yarn is called DT (D raw Tw is t). Using POY as the raw yarn, it is stretched and twisted by a stretching and twisting machine, with a small amount of twist applied to obtain DT. 100D/36F, 150D/36F, 50D/18F, etc. are methods for representing fiber specifications. The data above the diagonal line represents the fiber's fineness, and D is the fiber's fineness unit "dan", which is expressed in grams of 9000 meters of fiber length under standard conditions. For example, 100 grams of weight is 100 dan (100D); The data below the diagonal line represents the number of holes in the spinneret used during spinning, as well as the number of single filaments in the fiber of that specification. For example, 36F means that the spinneret used during spinning has 36 holes, which means that the fiber has 36 single filaments.
