Problems solved by technology

The dyeing mechanism of fluorescent paint is to use the electrostatic attraction between positive and negative charges to dye fibers, so conventional paint dyeing generally adopts the method of pad dyeing. This dyeing method is simple and easy to operate, but this pad dyeing method has certain limitations. Disadvantages: hard hand feeling, easy to stick to rolls, poor penetration dyeing, not yet used in package dyeing

Embodiment 1

[0014] Embodiment one: the density is 0.33g / cm 3 1. The cellulose fiber loose bobbin yarn with a weight of 1Kg carries out fluorescent red paint 5% dyeing, and the concrete steps are:

[0015] 1. Boiling and bleaching treatment: Bleaching and scouring in the same bath are used for pre-treatment of the cheese. The concentration of the three-in-one refining agent in the treatment solution is 3g / l, the concentration of hydrogen peroxide is 8g / l; the concentration of caustic soda is 4g / l l. The treatment temperature is 110°C, and the treatment time is 30 minutes. After the pretreatment, it is discharged, and then washed with hot water at 70°C for 10 minutes, and then washed with hot water at 50°C for 10 minutes. After the treatment, the residual liquid is drained.

[0016] 2. Pretreatment: put the cheese treated in step 1) into the dyeing vat, add polyvinylamine cationic modifier according to 7% of the cheese weight at 30°C, then raise the temperature to 70°C, and the heating rate...

Embodiment 2

[0019] Embodiment two: the density is 0.30g / cm 3 , a weight of 0.8Kg cellulose fiber loose bobbin carries out fluorescent yellow paint 5% dyeing, and the concrete steps are:

[0020] 1, boiling and bleaching treatment: with embodiment 1;

[0021] 2. Pretreatment: Put the cheese treated in step 1) into the dyeing vat, add polyvinylamine cationic modifier according to 5% of the weight of the cheese at 30°C, and then heat up to 70°C with a heating rate of 1°C / min. Keep warm for 50 minutes, set the pump speed of the dyeing vat to 85%, reverse the circulation direction of the dye liquor from inside to outside, 6 minutes from inside to outside, and 4 minutes from outside to inside, then drain the residual liquid, wash with hot water at 50°C for 10 minutes, and then discharge. The final cheese has a uniform positive charge;

[0022] 3. Dyeing: use dip dyeing method, bath ratio 1:8, add evenly at 30°C according to the proportion of 5% of the total volume of the dye solution in the c...

Embodiment 3

[0024] Embodiment three: the density is 0.25g / cm 3 , a weight of 0.5Kg cellulose fiber loose bobbin carries out fluorescent purple paint 5% dyeing, and the concrete steps are:

[0025] 1, boiling and bleaching treatment: with embodiment 1;

[0026] 2. Pretreatment: put the cheese treated in step 1) into the dyeing vat, add polyvinylamine cationic modifier according to 3% of the cheese weight at 30°C, then raise the temperature to 70°C, and the heating rate is 1°C / min. Keep warm for 50 minutes, set the pump speed of the dyeing vat to 80%, reverse the circulation direction of the dye liquor, 6 minutes from the inside to the outside, and 4 minutes from the outside to the inside, then drain the residual liquid, wash with hot water at 50°C for 10 minutes, and then discharge. The final cheese has a uniform positive charge;

[0027] 3. Dyeing: use dip dyeing method, bath ratio 1:15, 30 ℃ according to the ratio of 5% of the total volume of the dye solution in the chemical tank, add ...

Abstract

The invention provides a method for dyeing cellulose fiber cheeses with a fluorescent coating. The method is characterized by comprising the following steps: 1) scouring and bleaching treatment; 2) pretreatment, namely putting the cheeses treated in the step 1) previously into a vat, adding a polyvinylamine cationic modifier accounting for 3%-7% of the weight of the cheeses at 30+ / -1 DEG C, and then increasing the temperature to 70+ / -1 DEG C and preserving heat for 50+ / -1 minutes so that the treated cheeses carry even positive charges; 3) dyeing, wherein the bath ratio is 1:8 to 1:15, the starting dyeing temperature is 30+ / -1 DEG C, and the dye adding speed is controlled to the situation that dye is equally and evenly added by accounting for 5% of the total volume of a dye liquor in the vat in 30 minutes; after adding all the dye, increasing the temperature to 70+ / -1 DEG C and preserving heat for 30+ / -1 minutes, and then discharging residual liquor, and washing twice to remove floating color; 4) after-treatment, namely performing after-treatment on the dyed cheeses by use of an ethylene-vinlacetate copolymer flexible coating, thereby obtaining the cellulose fiber cheeses dyed with the fluorescent coating. The cheeses treated by use of the method are good in hand feeling and dye permeability, and are capable of meeting small-batch and multi-variety fast production requirements.

Description

technical field [0001] The invention relates to a fluorescent paint dyeing method for cellulose fiber cheese, belonging to the technical field of textile printing and dyeing. technical background [0002] Fluorescent paint has a complete spectrum, bright colors and low cost, and has been widely used in pad dyeing for a long time. The dyeing mechanism of fluorescent paint is to use the electrostatic attraction between positive and negative charges to dye fibers, so conventional paint dyeing generally adopts the method of pad dyeing. This dyeing method is simple and easy to operate, but this pad dyeing method has certain limitations. Disadvantages: hard hand feeling, easy to stick to rolls, poor penetration dyeing, so far it has not been applied to package dyeing. Contents of the invention [0003] The purpose of the present invention is to provide a fluorescent paint dyeing method for cellulose fiber cheese that can overcome the above-mentioned defects, has good hand feeli...
