Abstract

The invention provides a nylon high-shrinkage fiber which comprises a first high-shrinkage component and a second high-shrinkage component, wherein the first high-shrinkage component comprises a nylon 6 component and an antistatic component; and the second high-shrinkage component comprises a nylon 66 component and an antistatic component. Correspondingly, the invention also provides a preparation method of the nylon high-shrinkage fiber. The method comprises the following steps: 1. copolymerizing polycaprolactam and polyoxyethylene to prepare the antistatic component; 2. mixing the antistatic component prepared in the step 1 respectively with the nylon 6 component and nylon 66 to prepare the first high-shrinkage component and second high-shrinkage component; and 3. carrying out melt extrusion on the first high-shrinkage component and second high-shrinkage component through a double screw extruder to produce the shell-core high-shrinkage fiber. The nylon high-shrinkage fiber has the advantages of higher shrinkage and favorable antistatic effect, and is suitable for more textiles.

Description

technical field [0001] The invention relates to the technical field of nylon fibers, in particular to a nylon high-shrinkage fiber and a preparation method thereof. Background technique [0002] Fibers with a boiling water shrinkage rate of about 20% are called general shrinkage fibers, and fibers with a boiling water shrinkage rate of 35% to 45% are called high-shrinkage fibers. Compared with polyester and acrylic fibers, nylon has many advantages, such as strong wear resistance and high density. Small size, light fabric, etc. As a new type of textile raw material, nylon high-shrinkage fiber endows nylon with high shrinkage and moderate strength, which greatly broadens the application field of nylon. Boiled or steamed, the high-shrinkage fiber is curled, and the conventional fiber is curled into a circle due to the constraint of the high-shrinkage fiber, and the yarn is fluffy and round like a woolen yarn, which improves its product grade and increases the variety of patter...
