Problems solved by technology

[0002] The strength of polyester fiber is nearly 1 times higher than that of cotton and 3 times higher than that of wool, so the polyester fabric is strong and durable; but the water absorption and moisture regain of polyester fabric is low
Nylon has good strength and wear resistance, ranking first among all fibers, but nylon fabric has excellent elasticity and elastic recovery, and its nylon fabric is easy to wrinkle during wearing; with the improvement of people's living standards, people The requirements for wearing comfort are greatly improved, but the existing polyester fabrics and nylon fabrics cannot meet people's needs for clothing; for this reason, the application proposes a preparation method for polyester nylon knitted elastic fibers

Abstract

A preparation method of polyester-polyamide knitted elastic fibers comprises the following specific steps of S1, weighing an antibacterial agent, a surfactant, a microporous additive, a maleic anhydride grafted compatilizer, a lubricant and a flame retardant in parts by weight to obtain a mixture A, and dividing the mixture A into a mixture A1 and a mixture A2 in parts by weight; S2, weighing polyester slices and polyamide slices in parts by weight, respectively adding the polyester slices and the polyamide slices into the mixture A1 and the mixture A2, and heating to obtain polyester mixed molten liquid B1 and polyamide mixed molten liquid C1; S3, spinning and cooling to obtain polyester elastic fibers B2 and polyamide elastic fibers C2; S4, twisting the polyester elastic fibers B2 and the polyamide elastic fibers C2 to obtain polyester-polyamide elastic fibers; and S5, pressurizing and preserving heat of the polyester-nylon elastic fibers, and sequentially conducting cooling, oiling,drying, stretching, oiling and winding into a drum to obtain a finished product of the polyester-nylon elastic fibers. The preparation process is simple, the process is controllable, and the polyester-polyamide elastic fibers with excellent performance can be prepared.

Description

technical field [0001] The invention relates to the technical field of composite fibers, in particular to a preparation method of polyester-nylon knitted elastic fibers. Background technique [0002] The strength of polyester fiber is nearly 1 times higher than that of cotton and 3 times higher than that of wool, so polyester fabric is strong and durable; however, polyester fabric has low water absorption and moisture regain. Nylon has good strength and wear resistance, ranking first among all fibers, but nylon fabric has excellent elasticity and elastic recovery, and its nylon fabric is easy to wrinkle during wearing; with the improvement of people's living standards, people The requirements for wearing comfort are greatly improved, but the existing polyester fabrics and nylon fabrics cannot meet people's needs for clothing; therefore, the application proposes a preparation method of polyester nylon knitted elastic fibers.
