Example Embodiment

[0024] Example 1

[0025] A dyeing method for achromatic blended fabric, including the following steps:

[0026] Step 1: Pre-treatment of bagasse: Rinse the bagasse raw materials with clean water, dry the bagasse in an oven at 45°C, mechanically pulverize the dried solid material for 6 times and then pass it through a 25-mesh sieve. Take the sieve;

[0027] Step 2: The mechanically crushed bagasse is further ultrasonically pulverized: pure water is used as the solvent, the ultrasonic power is 1280W, and the material-to-liquid ratio is 1:6, after further ultrasonic pulverization for 35 minutes, and then filtered to obtain the bagasse-containing filtrate; The filtered residue can continue to be ultrasonically crushed;

[0028] Step 3: Then process the ultra-high pressure nanometer 265MPa to a particle size of 30-100nm, and then concentrate and spray dry to obtain bagasse nano powder;

[0029] Step 4: Put the bagasse nano powder into the madder natural dye concentrate and add acetic acid...

[0040] Example 2

[0041] A dyeing method for achromatic blended fabric, including the following steps:

[0042] Step 1: Pretreatment of bagasse: Rinse the bagasse raw materials with clean water, dry the bagasse in an oven at 50°C, and perform repeated mechanical pulverization of the dried solid material 5 times, and then pass it through a 25-mesh sieve. Take the sieve;

[0043] Step 2: The mechanically crushed bagasse is further ultrasonically crushed: pure water is used as the solvent, the ultrasonic power is 1500W, and the material-to-liquid ratio is 1:5, after further ultrasonic crushing for 40 minutes, and then filtered to obtain the bagasse-containing filtrate; The filtered residue can continue to be ultrasonically crushed;

[0044] Step 3: Then process the ultra-high pressure nanometer 250MPa equipment to a particle size of 30-100nm, and then concentrate and spray dry to obtain bagasse nano powder;

Abstract

The invention discloses a dyeing method of a blended fabric without the color difference. Bagasse is used as a main raw material to dye the blended fabric, and a small amount of acetic acid, hydrogenperoxide and an OPE penetrating agent are added, the dyeing effect of natural dye on polyester fibers can be remarkably improved, and therefore the dyed blended fabric can be high in color fastness, and the color difference between natural fibers and chemical fibers can be eliminated. Meanwhile, the bagasse can be subjected to waste utilization, and the environmentally-friendly production technology requirements are met.

Description

technical field [0001] The invention relates to the technical field of textile dyes, in particular to a method for dyeing blended fabrics without color difference. Background technique [0002] In human history, natural dyes have made indelible contributions to the beautification of people's lives. Since the end of the 19th century, due to the rapid development of synthetic dyes, natural dyes have basically withdrawn from the field of fabric dyeing. With the increasing awareness of human environmental protection and the increasing concern for their own health, the harm of some synthetic dyes to human health and the ecological environment has become more and more noticeable. With the improvement of modern technology level, especially the improvement of modern manufacturing level, people have higher and higher requirements for the safety and health care of the clothing industry, and natural dyes have begun to be valued by people again. Animal and vegetable dyes in natural dy...
