Embodiment 1

[0047] The preparation method of antibacterial functional finishing agent is:

[0048] Add 120mL of acetone, 12 parts of nano-zinc oxide, 3 parts of KH-570γ-methacryloxypropyltrimethoxysilane into the stirred tank, stir and react at 40°C for 24 hours, centrifuge the mixture, and wash it twice with methanol , and dried at 70°C to obtain surface-modified nano-zinc oxide for subsequent use;

[0049] Weigh 8 parts of methyl methacrylate, 26 parts of butyl acrylate, and 4 parts of acrylic acid, stir and mix to form a monomer mixture;

[0050] Another 0.5 part of potassium persulfate was dissolved in 20 parts of water to make an aqueous initiator solution;

[0051]146 parts of water, 5 parts of surface-modified nano-zinc oxide, 11 parts of acryloyloxyethyl-propyltrimethoxysilane-dimethylammonium chloride, 3 parts of dodecyldimethylbenzyl chloride Ammonium, 2 parts of dioctadecyl dimethyl ammonium chloride, 3 parts of AEO-9 were placed in the reaction kettle, stirred and heated to ...

Embodiment 2

[0056] The short-process dyeing and finishing process of brocade sticky fabrics includes the following steps:

[0057] (1), pre-processing

[0058] (1) Squeeze liquid to stand still

[0059] Technological process: two dipping and two rolling (over 100% rolling rate) → open width coil → stacking

[0060] Process prescription (g / L):

[0061]

[0062] Wrap tightly with plastic film to prevent air drying, resulting in uneven desizing, and rotate and stack at room temperature for 12 hours;

[0063] (2) Efficient open width washing

[0064] Wash the stacked Nylon fabric with open-width washing machine to wash off various sizing, additives and contaminated impurities on the gray fabric; completely remove the spinning oil added during the spinning process of nylon to prevent Cloud spots will appear during dyeing, the temperature of the water tank is: 90°C, 90°C, 95°C, 90°C, 85°C, 80°C;

[0065] (2), Pre-type

[0066] 180~190℃, time 30s, speed 40~45m / min;

Abstract

The invention discloses a short-process dyeing and finishing process for a polyamide viscose fabric. The short-process dyeing and finishing process comprises the following steps of preprocessing, presetting, dyeing and post-processing, the preprocessing comprises (1) standing of a rolling liquid and (2) efficient open-width washing, the technological process of standing the mangling liquid comprises soaking for twice and rolling for twice (liquid rate is more than 100%), implementing open-width packaging, stacking, tightly packaging by using a plastic film to prevent air drying and even desizing, rotatably stacking for 12 hours at the room temperature, the stacked polyamide viscose fabric is washed with water through an open width water washing machine in the process of efficient open-width washing, the temperature of a water tank is 90 DEG C, 90 DEG C, 95 DEG C, 90 DEG C, 85 DEG C and 80 DEG C; the presetting lasts for 30 seconds at the temperature of 180-190 DEG C at the speed of 40-45 m / min; a dyeing formula comprises a neutral acid dye, an Argazol NF series neutral fixation active dye and 1g / L of a levelling agent, the bath ratio is 1:8; a post-processing formula comprises 8-15g.L<-1> of an anti-bacterial functional finishing agent, the setting temperature is 190-200 DEG C, the time is 30-45 seconds, and the speed is 30-40 m / min.

Description

technical field [0001] The invention relates to a dyeing and finishing process of textiles, in particular to a short-process dyeing and finishing process of brocade-bonded fabrics, which belongs to the field of textile dyeing and finishing. Background technique [0002] Nylon Nylon fabric is a kind of textile fabric that is widely loved by consumers. Nylon fiber is widely used in formal wear, leisure sportswear and other purposes due to its good strength and toughness, excellent wear resistance and resilience. Its durability, durability and abrasion resistance are about 4-5 times that of wool, and are deeply loved by people; but nylon fiber is also a kind of hydrophobic fiber, which feels impermeable and airtight when used, while viscose fiber It is a hydrophilic fiber, which has the advantages of breathability and moisture permeability, but it does not have the advantages of good elasticity of nylon fiber, and it is easy to wrinkle and not crisp. Nylon and viscose fibers a...
