Silk fiber knitted fabric dyeing method for achieving fluorescent color

Abstract

The invention discloses a silk fiber knitted fabric dyeing method for achieving a fluorescent color. The dyeing method comprises the following steps: adding a scoured and bleached silk fiber knitted fabric into a machine, adding water, starting a cycle, adding a wetting agent, adjusting the pH value of a work solution to 4-5 with acetic acid, and starting heating; adding a modifier; heating, wherein a heating rate is 1-2 DEG C / min; carrying out thermal insulation for 30 min, wherein the temperature is 75-80 DEG C; adding soda ash to adjust the pH value of the work solution to 9-10; draining the solution, and carrying out water washing; adding water, acetic acid, a cationic fluorescent dye, and a leveling agent; heating, wherein the heating rate is 1-2 DEG C / min; carrying out thermal insulation; draining the solution, and carrying out water washing; soaping; carrying out water washing; carrying out color fixation, wherein the amount of a color fixation agent is 2-5% owf, and the temperature is 65-70 DEG C; and drying. According to the present invention, the silk fibers are modified, and the existing cationic fluorescent dye is adopted to achieve fluorescent dyeing of the silk fiber knitted fabric, such that the fabric achieves a fluorescent color, and adverse impact of fluorescent coating material dyeing on fabric wearability and the problem of difficulty in achieving industrial production are overcome.

Description

technical field [0001] The invention belongs to the technical field of silk fiber dyeing, in particular to a method for dyeing silk fiber knitted fabrics to obtain fluorescent colors. Background technique [0002] The dyeing technology of silk fiber has been very mature, and the traditional dyeing process and methods have been able to meet the needs of most consumers. But along with the raising of people's living standard and the development of social civilization progress, the silk product of common color and luster and clothes thereof that conventional dyeing obtains can't satisfy requirement. In the past one or two years, the demand for fluorescent-colored textiles in the international and domestic markets has been increasing, and the demand for fluorescent colors in silk and its products (clothing and fabrics, etc.) has also shown a relatively strong growth trend. Many domestic textile enterprises have received orders for fluorescent silk fiber textile fabrics or yarns ...

Problems solved by technology

[0010] Although this dyeing process can dye silk fiber knitted fabrics in fluorescent colors, the dyed fabrics feel rough and lose the inherent excellent performance of silk fabrics. Even if the style of silk fabrics can be kept to a large extent, the cost of dyeing and There are big problems in machine pollution cleaning, dyeing yield, etc.
