[0031] 3) Antibacterial finishing: dip the dyed blended fabric into the turnip extract solution at room temperature for 15 minutes, and then dehydrate, wherein the concentration of the turnip extract aqueous solution is 35g / L;

[0032] 4) Drying: Put the antibacterially finished blended fabric into the dryer to dry.

[0033] In the step 3), the preparation method of turnip extract is as follows: (a) crush the dry root (8kg) of t...

Embodiment 2

[0036] An antibacterial textile printing and dyeing process, the specific method steps are as follows:

[0037] 1) Bleaching: Dip the textile into the bleaching solution and wash and bleach it;

[0038] 2) Dyeing: heat up to 75°C at a rate of 2.5°C / min and hold for 3 minutes; then continue to heat up to 100°C at a rate of 1.5°C / min and hold for 5 minutes; then continue to heat up to 120°C at a rate of 1.5°C / min. Keep warm for 40 minutes; finally cool down to 60°C at a rate of 2.5°C / min, keep warm for 10 minutes, and the dyeing is completed;

[0039] 3) Antibacterial finishing: dip the dyed blended fabric into the turnip extract solution at room temperature for 55 minutes, and then dehydrate, wherein the concentration of the turnip extract aqueous solution is 5g / L;

[0040] 4) Drying: Put the antibacterially finished blended fabric into the dryer to dry.

[0041] Preferably, in the step 3), the preparation method of the turnip extract is the same as that in Example 1.

Embodiment 3

[0043] An antibacterial textile printing and dyeing process, the specific method steps are as follows:

[0044] 1) Bleaching: Dip the textile into the bleaching solution and wash and bleach it;

[0045] 2) Dyeing: heat up to 72°C at a rate of 2.5°C / min and hold for 5 minutes; then continue to heat up to 100°C at a rate of 1.5°C / min and hold for 5 minutes; then continue to heat up to 120°C at a rate of 1.5°C / min. Keep warm for 30 minutes; finally cool down to 60°C at a rate of 2.5°C / min, keep warm for 6 minutes, and the dyeing is completed;

[0046] 3) Antibacterial finishing: dip the dyed blended fabric into the turnip extract solution at room temperature for 20 minutes, and then dehydrate, wherein the concentration of the turnip extract aqueous solution is 15g / L;

[0047] 4) Drying: Put the antibacterially finished blended fabric into the dryer to dry.

[0048] Preferably, in the step 3), the preparation method of the turnip extract is the same as that in Example 1.

Abstract

The invention discloses a process for printing and dyeing antibacterial textiles. The particular method includes steps of 1), bleaching the textiles, to be more specific, impregnating the textiles in bleaching solution and washing and bleaching the textiles; 2), dyeing the textiles, to be more specific, heating the textiles at the speed of 2.5 DEG C / min until the temperatures of the textiles reach 70-75 DEG C, preserving heat of the textiles for 3-10 min, heating the textiles at the speed of 1.5 DEG C / min until the temperatures of the textiles reach 100 DEG C, preserving heat of the textiles for 5 min, heating the textiles at the speed of 1.5 DEG C / min until the temperatures of the textiles reach 120 DEG C, preserving heat of the textiles for 25-40 min, cooling the textiles at the speed of 2.5 DEG C / min until the temperatures of the textiles reach 60 DEG C and preserving heat of the textiles for 5-10 to completely dye the textiles; 3), carrying out antibacterial finishing, to be more specific, impregnating the dyed blended textiles in turnip extract aqueous solution at the normal temperature for 15-55 min and dewatering the dyed blended textiles; 4), drying the textiles and the like. The concentration of the turnip extract aqueous solution is 5 g / L-35 g / L. The method has the advantages that antibacterial weaving dye is low in production cost, bacteria represented as Escherichia coli, staphylococcus aureus and tritirachium album can be effectively suppressed, the suppression rate can reach 99%, and influence of conventional washing can be prevented.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to an antibacterial textile printing and dyeing process. Background technique [0002] Microorganisms are a group of small, simple structures and various types that exist in nature and cannot be directly seen by the naked eye. [0003] of a tiny creature. Among them, bacteria are prokaryotic microorganisms with strong aquatic properties, and they are also one of the important species of microorganisms. [0004] Textiles are an excellent medium for the growth of microorganisms, and fiber products, especially cotton, hemp, wool and silk products mainly composed of cellulose, collagen, keratin and silk fibroin, are very vulnerable to the harm of microorganisms. Favorable conditions on the textiles close to the human body, such as temperature and humidity, can cause bacteria, molds, yeasts and other microorganisms to multiply rapidly, and decompose various organic substanc...
