CN101713154A - Clean-free process and application method of dacron textile printing - Google Patents

Abstract

The invention aims at providing a clean-free process used for dacron textile printing and an application method. By adopting the dacron textile printing, cleaning is not needed after the step of color fixing, and softener can be directly applied for sizing. The invention has the advantages that cost on printing paste is reduced by 30-60 percent, the printing disperse dye can be saved by 30-70 percent, rotary screen printing speed can be improved by 30-100 percent, printing pattern is clear with obviously improved brilliant shade, and all color fastness reaches or exceeds a national textiles standard. Because the cleaning process is reduced, large amount of steam, electric energy and water are saved without discharging large amount of waste water from cleaning, the purpose of energy saving and emission reduction is achieved.

Description

The dacron stamp is exempted from cleaning and using method

Technical field:

The present invention relates to textile printing and dyeing industry, be meant that specifically a kind of dacron stamp exempts from cleaning and using method:

Prior art:

The dacron stamp adopts DISPERSE DYES, printing gum adopts sodium alginate, carboxymethyl starch, plant seed glue etc., the print paste modulation is according to mill base viscosity, adds a small amount of thickener, fixation behind the stamp, the process using high temperature steaming, high-pressure steam method or high temperature bake method, adopt rope form continuous washing technology or open width continuous washing technology after the fixation, special dark color is also comprised reduction cleaning, remove on the dacron the not dye well printing gum of fixation, a large amount of dye vapour of this technology waste, electric energy and a large amount of water, produce a large amount of dyeing and printing sewages simultaneously, clean totally also can not produce and cut marks, defects such as Seepageization influence the quality of stamp finished product.

Summary of the invention:

The present invention is intended to propose a kind of dacron stamp that is used for and exempts from cleaning and using method, adopt dacron stamp of the present invention, need not clean after the fixation, directly go up the softener typing, the printing gum cost reduces 30-60%, the stamp DISPERSE DYES is saved 30-70%, the ROTARY SCREAM PRINTING speed of a motor vehicle can improve 30-100%, stamp flower type is clear, and vividness obviously improves, and every COLOR FASTNESS meets or exceeds national textile standards. reduced matting, save a large amount of steam, electric energy and water have not had a large amount of cleaning sullages, have reached the purpose of energy-saving and emission-reduction.

Embodiment:

For realizing above purpose, the present invention realizes by the following aspects:

1: employing＜a kind of slurry DISPERSE DYES 〉, this technology has been applied for national inventing patent, adopts this dyestuff can reduce migration, significantly improves the dyestuff dye-uptake, (this dyestuff is produced by the Jiaxing City trade Co., Ltd that extensively starts construction)

2: printing gum adopts synthetic thickening agent, reduces the solid content of printing gum, makes PRINTED FABRIC keep original feel, improve simultaneously color depth and bright-colored degree.

3: PRINTED FABRIC employing heated dry air (190 ℃-210 ℃, 1-5min), the instant heating blow.

4: the dry method typing is adopted in typing, and as adding softener, fire retardant or other auxiliary agents can adopt the feeding of spraying humidification machine, rolls through padding machine to enter the setting machine typing again.

The present invention adopts above scheme, can reach to exempt to clean purpose, and its technological process is for drawing a design-size mixing-stamp oven dry-hot melt set-typing-check-link code finished product.

Case study on implementation 1

Fabric: dacron simulation silk fabrics look fourth (through pre-treatment)

The print paste prescription:

Exempt to clean pulp-shaped dispersed dyes bright red R (Jiaxing City extensively start construction trade Co., Ltd) 2%

Exempt to clean thickener (Jiaxing City extensively start construction trade Co., Ltd) 4%

Softener 3%

Water 91%

Claim that earlier water 91kg adds the 4kg thickener, beater stirring at low speed 2 minutes adds pulp-shaped dispersed dyes bright red R 2kg again, softener 3kg, and middling speed stirred 1～2 minute, and mill base evenly gets final product.

Technological process: ROTARY SCREAM PRINTING, oven dry (80 meters/minute of the speed of a motor vehicle) → hot melt set (190 ℃, 5min) → typing → check → link code finished product.

Case study on implementation 2

Fabric: terylene sanding peach face

The print paste prescription:

Exempt to clean the black B of pulp-shaped dispersed dyes (Jiaxing City extensively start construction trade Co., Ltd) 10%

Exempt to clean thickener (Jiaxing City extensively start construction trade Co., Ltd) 4%

Softener 3%

Water 83%

Added 4kg thickener stirring at low speed 2 minutes in 83kg water, and added and exempt to clean pulp-shaped dispersed dyes 10kg and softener 3kg, middling speed stirred 1～2 minute, and mill base evenly gets final product.

Technological process. the set of PLATE SCREAM PRINTING oven dry → hot melt (200 ℃, 150s) → typing → check → link code finished product.

Claims (3)

1. the dacron stamp is exempted from cleaning and using method, and its technological process is: mill base preparation → stamp oven dry → hot melt set → typing → check → link code → finished product.

2. the mill base described in the claim 1 is prepared its composition by pulp-shaped dispersed dyes, thickener, and softener, water is formed.

3. its technological parameter of hot melt set described in the claim 1 is 190 ℃-220 ℃ of temperature, 1 minute-5 minutes time.
