Embodiment 1

[0041]According to the bath ratio of 1:15 and the temperature of 80 degrees Celsius, the linen raw material was desized in a sodium hydroxide solution with a concentration of 5 g / L for 10 minutes. Scouring the desizing-treated linen once with deionized water until the pH of the scouring solution is 6.5. Put the scoured linen into a hydrogen peroxide solution with a concentration of 1 gram per liter, and bleach it for 20 minutes at a temperature of 50 degrees Celsius. The bleached linen is 1:100 in mordant bath ratio, 1:10 in mass ratio of printing and dyeing auxiliaries to mordant, 1% owf curcumin is added as mordant, and 2,3-epoxypropyl Trimethylammonium chloride was used as a printing and dyeing auxiliary agent, and sodium sulfate was added as an electrolyte auxiliary agent according to the mass ratio of sodium sulfate and mordant dyeing agent at 1:1, and the linen product 1 was obtained by mordant dyeing for 20 minutes.

Embodiment 2

[0044] According to the bath ratio of 1:30 and the temperature of 100 degrees Celsius, the linen raw material was subjected to desizing treatment in a sodium hydroxide solution with a concentration of 50 g / L for 30 minutes. The desizing-treated linen was scoured five times with deionized water until the pH of the scoured solution was 6.5. Put the scoured linen into a hydrogen peroxide solution with a concentration of 10 g / L, and bleach it for 60 minutes at a temperature of 80 degrees Celsius. The bleached linen cloth is 1:500 in mordant bath ratio, 1:50 in mass ratio of printing and dyeing auxiliaries to mordant, add 10% owf acid lake blue as mordant, add tartaric acid as printing and dyeing auxiliaries, according to The mass ratio of sodium sulfate to mordant is 1:2. Add sodium sulfate as an electrolyte additive and carry out mordant dyeing for 100 minutes to obtain linen product 2.

Embodiment 3

[0047] According to the bath ratio of 1:22 and the temperature of 90 degrees Celsius, the linen raw material was desized in a sodium hydroxide solution with a concentration of 30 g / L for 20 minutes. The desizing-treated linen cloth was scoured 3 times with deionized water until the pH value of the scoured solution was 7. Put the scoured linen into a hydrogen peroxide solution with a concentration of 6 g / L, and bleach it for 40 minutes at a temperature of 65 degrees Celsius. Add 6% owf active red X-3B as mordant to the bleached linen according to the mordant bath ratio of 1:300, and the mass ratio of printing and dyeing auxiliaries to mordant as 1:30, and add benzalkonium chloride as mordant. As for printing and dyeing auxiliaries, add sodium sulfate as electrolyte auxiliaries according to the mass ratio of sodium sulfate and mordant dyeing agent at 1:1.5, and carry out mordant dyeing for 60 minutes to obtain linen product 3.

Abstract

The invention a linen printing and dyeing method with high dye-uptake rate, as well as a linen product printed and dyed by the method. The method comprises the following steps: conducting destarching treatment, boiling-off treatment and bleaching treatment on a linen raw material in sequence, and conducting printing and dyeing treatment to obtain the linen product, wherein the printing and dyeing auxiliary is one or more of 2,3-epoxypropyltrimethyl ammonium chloride, tartaric acid and benzalkonium chloride, and the mass ratio of the printing and dyeing auxiliary to a dye mordant is 1:(10-50). According to the provided linen printing and dyeing method with high dye-uptake rate, linen can be dyed with very high tint amount, and the printed and dyed linen has very high friction resistance and very high water washing resistant color fastness. Besides, the provided linen printing and dyeing method is low in raw material cost, simple to operate, good in operability and very suitable for industrial printing and dyeing.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a linen printing and dyeing method with high dye uptake and a linen product printed and dyed by the method. Background technique [0002] The origin of clothing has a history of thousands of years. It has been a long process from using animal skins and leaves to keep warm, to consciously raising silkworms and drawing silk to weave cloth. The ancients learned to extract fibers from hemp and cotton, spin and weave cloth. Today people have learned to refine synthetic fibers from chemistry. Weaving techniques are also becoming more and more exquisite, from simple plain weave, twill weave, satin weave, to complex changing weave, double weave and jacquard weave. However, with the development of society and the advancement of technology, people are no longer satisfied with its thermal performance and appearance, and gradually pay attention to its wearing performance. According to ...
