Dyeing method for nylon or naked ammonia seamless knitted fabric

Abstract

The invention discloses a dyeing method for a nylon or naked ammonia seamless knitted fabric. The dyeing method comprises the steps of: 1, white body fabric drying: placing a fabric product into a finished garment drying machine to dry for at least 20 minutes at a drying temperature of 75 to 85 DEG C at a temperature rising rate of 2 DEG C per minute, after heat preservation is finished, cooling to a temperature of 45 DEG C, and taking out the fabric product; 2, to-be-dyed preparation: tidying the dried product according to a size, tidily placing the product into a circulation barrel, and adding hot water with a temperature of 40 DEG C to 50 DEG C to soak for treatment time of at least 15 minutes; and 3, dyeing: placing the soaked product into a jar, adding water, an assistant and a dye according to dyeing requirements, heating to a temperature of 90 to 100 DEG C at a rate of 0.5 to 1 DEG C per minute, after carrying out heat preservation for at least 30 minutes, draining water, washing for 10 to 20 minutes with hot water with a temperature of 35 to 45 DEG C, taking the product out of the jar, carrying out dehydration, drying for 20 to 30 minutes at a temperature of 75 to 85 DEG C,and cooling to a temperature of 45 DEG C. by the dyeing method, chicken paw print shaped creases can be prevented from being generated on the fabric.

Description

technical field [0001] The invention belongs to the field of dyeing and finishing of seamless underwear, specifically a dyeing method of nylon or naked ammonia seamless knitted fabric, which prevents chicken paw prints from being produced on the surface of the fabric after dyeing, and is suitable for seamless shaping clothes and seamless shaping shorts , seamless shaping belly roll, seamless shaping jumpsuit and other seamless knitted fabrics woven with nylon or spandex. Background technique [0002] Seamless shaping knitted fabric, weaving raw materials mainly choose nylon or naked ammonia yarn. Nylon is characterized by wear resistance, light weight and soft touch. Naked ammonia is characterized by high elasticity, excellent stretching and recovery properties. It is especially suitable for seamless shaping fabrics when used in combination with other yarns for weaving. After the yarn is selected, it is three-dimensionally woven by the Santoni seamless underwear machine. ...

AI Technical Summary

Problems solved by technology

[0003] Due to the high elasticity of the seamless shaping knitted fabric, the fabric will shrink irregularly when encountering water or high temperature during the dyeing and finishing process. The creases in the form of paw prints cannot be completely eliminated even after high-temperature ironing or steaming, which will affect the aesthetics of the product after it is finished.
