Embodiment 1

[0019] Add 10 grams of reactive red, 10 grams of sodium carbonate, and 10 grams of sodium sulfate to 1 liter of water to form a dye solution. After the dye solution is heated to 60 degrees, pearl fiber fabrics are put into the dye solution. The bath ratio is 25:1. When the pH is 6, continue to heat up the dye liquor at a rate of 2 degrees per minute. After the dye liquor is heated to 90 degrees, keep the temperature for 100 minutes, then take out the fabric and wash it until neutral, then dry it.

Embodiment 2

[0021] Add 15 grams of reactive red, 15 grams of sodium carbonate, and 20 grams of sodium sulfate to 1 liter of water to form a dye solution. After the dye solution is heated to 55 degrees, pearl fiber fabrics are put into the dye solution. The bath ratio is 30:1. When the pH is 7, continue to heat up the dye liquor at a rate of 2 degrees per minute. After the dye liquor is heated to 100 degrees, keep the temperature for 80 minutes, then take out the fabric, wash it until neutral, and dry it.

Embodiment 3

[0023] Add 25 grams of reactive blue, 20 grams of sodium carbonate, and 30 grams of sodium sulfate to 1 liter of water to form a dye solution. After the dye solution is heated to 50 degrees, pearl fiber fabrics are put into the dye solution. The bath ratio is 28:1. When the pH is 7, continue to heat up the dye liquor at a rate of 2 degrees per minute. After the dye liquor is heated to 70 degrees, keep the temperature for 90 minutes, then take out the fabric and wash it until neutral, then dry it.

Abstract

The invention provides a reactive dyeing method for pearl viscose fibers. The reactive dyeing method mainly comprises the following steps of: dyeing, wherein reactive dyes, sodium carbonate and sodium sulfate are added in water to form dye liquor, pearl viscose fiber fabric is put into the dye liquor after the dye liquor is heated to be at a temperature ranging from 50 DEG C to 60 DEG C, the liquor ratio equals to (25-30):1, the pH of the dye liquor equals to 6 to 7.5, and then the dye liquor is heated continually to reach a temperature ranging from 70 DEG C to 100 DEG C and is kept at the temperature for 80 minutes to 100 minutes, thereby dyeing the fabric; washing the dyed fabric till the fabric is neutral; and drying the fabric. According to the dyeing method, the composition and component proportion of the dye liquor are optimized, the parameters of the dyeing process are adjusted, the dyeing is easy, and the dye-uptake and color fastness of the pearl viscose fibers are improved.

Description

technical field [0001] The invention relates to a dyeing method, in particular to a pearl viscose fiber reactive dye dyeing method. Background technique [0002] Pearl fiber is a fiber made by blending and spinning nano-pearl particles and viscose. It is a new type of functional fiber. Nano-pearl particles are evenly distributed inside and outside the fiber. Because pearls contain a variety of amino acids needed by the human body And trace elements, long-term contact with the skin, has the effects of nourishing skin and skin care, anti-ultraviolet rays, and emitting far-infrared rays. But the dyeing method about this pearl viscose fiber in the prior art is not ideal, mainly is that it is difficult to dye, and the color fastness after dyeing is low. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a pearl viscose fiber reactive dyeing method that is easy to dye and has high color fastness a...
