Manufacturing method of high-elasticity cotton/polyurethane knitted fabric

Abstract

The invention discloses a manufacturing method of high-elasticity cotton / polyurethane knitted fabric. The manufacturing method includes the steps of raw material preparation, wherein pima cotton and polyurethane filaments are prepared; the weaving technology, wherein the pima cotton serves as face yarn, the 40 D Lycra serves as bottom yarn, and the face yarn is always located on the front face of the fabric; the preshaping technology, wherein the manufactured fabric is preshaped, the temperature of a shaping machine is set to be 190-200 DEG C, and the speed of the shaping machine is 20-25 m / min; the dyeing technology, wherein the dyeing process includes pretreatment, cotton dyeing and aftertreatment technical flow processes; the afterfinish technology, wherein vibrating drying is carried out after dyeing is completed, the drying temperature is 130 DEG C, a softening agent is added after drying for final shaping, the shaping temperature is 130 DEG C, and the speed is 15-20 m / min. The manufacturing method has the advantages that the manufactured fabric is soft and comfort in handfeel, high in hygroscopicity and gas permeability and ultrahigh in elasticity and resilience and is suitable for manufacturing high-grade knitted underwear and specially functional sports clothes such as a kneecap support, an elbow support, waist support and a leotard.

Description

technical field [0001] The invention relates to the related technical field of textile preparation, in particular to a method for preparing a cotton spandex high-elasticity knitted fabric. Background technique [0002] There are many kinds of textile fibers, which are usually divided into two categories: natural fibers and chemical fibers. Cotton is a kind of bulk natural cellulose fiber, and it is the only product among the main agricultural products such as grain, cotton, oil and vegetables that can meet the needs of human beings for wearing and using. Compared with chemical fibers, the fabric made of cotton fibers has good softness and comfort, strong moisture absorption and air permeability, good warmth retention, and there is no adverse reaction such as static electricity, and it is green and healthy, and will not cause adverse reactions on human skin. Spandex is a functional fiber with high elasticity and recovery. As long as a small amount of spandex yarn is added to...

AI Technical Summary

Problems solved by technology

[0003] Although ordinary cotton and spandex knitted fabrics have certain elasticity and resilience, they cannot meet the requirements of some special high-elasticity functional fabrics, such as knee pads, elbow pads, waist pads, tights, etc. The requirements for such fabrics are extremely high. Excellent elasticity and recovery, in order to ensure that the human body still feels comfortable and fit when the range of human movement is large
