Description

Technical Field

[0001] The invention relates to the technical field of fabric dyeing, in particular to a dyeing method for making bird's nest cloth fabric have anti-pilling and anti-static functions. Background Art

[0002] Bird's Nest fabric is a blend of polyester and cotton fibers. Since polyester has good anti-wrinkle and anti-deformation properties, and cotton fibers have a comfortable feel and breathability, the blended fabric has both anti-wrinkle properties and comfort, so it is very popular. The wearing characteristics of Bird's Nest fabric are as follows:

[0003] Advantages: (1) Good wrinkle resistance: Polyester has good wrinkle resistance and deformation resistance. The blended fabric is more wrinkle-resistant than pure cotton fabric and is not easy to wrinkle. (2) Easy to maintain: Blended fabric is easy to maintain and can be machine washed. It is not easy to deform, fade or shrink. (3) Comfortable: Cotton fiber has a comfortable feel and breathability. The blended fabric has both wrinkle resistance and comfort.

[0004] Disadvantages: (1) Prone to static electricity: Polyester is prone to static electricity, which may cause discomfort and collision noise when worn. (2) Prone to pilling: Polyester fibers are prone to pilling, so bird's nest fabrics need to pay attention to the pilling problem. (3) Not resistant to high temperatures: Polyester is not resistant to high temperatures and is prone to deformation when the temperature exceeds 60°C. Therefore, high-temperature irons cannot be used to iron blended fabrics.

[0005] In order to improve the performance of bird's nest cloth fabrics, it is necessary to develop a dyeing method that makes the bird's nest cloth fabrics have anti-pilling and anti-static functions. Summary of the invention

[0049] Example 1

[0050] A dyeing method for making bird's nest cloth fabric have anti-pilling and anti-static functions, the steps are as follows:

[0051] (1) Preparation of Bird's Nest Fabric: Bird's Nest Fabric uses 80 / 20 polyester-cotton blended 32-count yarn, circular knitted double-sided structure, and 80D polyester yarn is used in the middle to strengthen the fabric. The weight of Bird's Nest Fabric is 300g / m 2 .

[0052] (2) Dyeing: Use Hong Kong Lixin high temperature and high pressure L-type dyeing machine, first inject clean water into the dyeing vat, set the bath ratio to 1:10, add 2 g / L of leveling agent HS-303A (that is, the concentration of the leveling agent in clean water is 2 g / L, and the meaning of other reagents expressed in this form below is the same as here), turn on the main pump to disperse the leveling agent evenly, and put the bird's nest cloth into the dyeing vat through the dyeing vat window. Run for 15 minutes. After the bird's nest cloth is completely smooth in the vat body, adjust the power of the main pump to 70%, and control the circulation time of the bird's nest cloth in the dyeing machine to 2.5 minutes. Add pH stabilizer AT 2g / L, after running for 5 minutes, add 100g / L of accelerator sodium sulfate, raise the temperature to 45℃ and keep constant, inject polyester-cotton one-bath dye TC-B black (the dosage is 5.5wt% of the quality of bird's nest cloth grey cloth) into the dye bath, raise the temperature to 133℃ and keep warm for 50 minutes. In order to ensure the level dyeing effect, the heating rate is controlled at 1℃ / min. In order to avoid chicken claw marks on the fabric due to too fast cooling, the cooling rate is controlled at 0.8℃ / min. Cool down to below 60℃, take samples for color matching, drain the liquid, add clean water for 15 minutes and then drain the liquid, and wash with water twice in total.

[0053] (3) Bioenzyme polishing: Continue to add clean water to the dye vat, set the bath ratio to 1:6, turn on the heating device after adding, heat the water to 58°C, then turn off the heating device, add liquid neutral cellulase 280 / 800 (the dosage is 0.3wt% of the weight of the bird's nest cloth), run for 50 minutes, and no drainage is required after the operation is completed.

[0054] (4) Soap washing: Add 3 g / L of polyester-cotton soap detergent Ayoubao RCN into the dye vat, heat it to 95°C and wash it for 30 minutes. After draining, add clean water and control the temperature to 80°C for 15 minutes before draining.

[0055] (5) Color fixation: Continue to inject clean water into the dye vat, set the bath ratio to 1:6, and add 3 g / L of polyester-cotton color fixative HS-3. After running for 30 minutes, use the method of adding soda ash and washing powder to test the color fastness and then drain the liquid.

[0056] (6) Finishing: A Monforts stenter setting machine (10 boxes) was used to stenter and set the bird's nest fabric after color fixation. The frame controlled the width naturally, the overfeed was controlled to +2, the speed was 35 m / min, the temperature of the first section was 150° C., the temperature of the tenth section was 150° C., and the temperature of the other eight sections was controlled at 180° C. 3 wt% of the anti-pilling agent HY-812 (diluted with clean water to a concentration of 20 g / L) and 1 wt% of the antistatic agent TN (diluted with clean water to a concentration of 20 g / L) were added to the feeding point of the stenter setting machine relative to the weight of the bird's nest fabric grey fabric. The feeding point of the setting machine was located at the front of the setting machine. The anti-pilling agent HY-812 and the antistatic agent TN were first dipped and rolled into the bird's nest fabric after color fixation by a dipping and rolling method, and then passed through 10 boxes of the stenter setting machine in sequence to obtain the final bird's nest fabric with anti-pilling and anti-static functions.

[0057] Comparative Example 1

[0058] The same as Example 1, except that the anti-pilling agent HY-812 is omitted in step (5).

[0059] Comparative Example 2

[0060] The same as Example 1, except that the use of the antistatic agent TN is omitted in step (5).

[0061] Comparative Example 3

[0062] Same as Example 1, except that the use of liquid neutral cellulase 280 / 800 is omitted in step (3).

[0063] Effect verification

[0064] (1) Anti-pilling effect test

[0065] The test is carried out according to the circular locus method in GB / T 4802 "Determination of the pilling properties of textile fabrics": use a nylon brush and a fabric abrasive or only a fabric abrasive to rub the fabric to cause pilling.

[0066] After testing, the anti-pilling effect of the bird's nest cloth fabric finally obtained in Example 1 can reach level 3.5; the anti-pilling effect of the bird's nest cloth fabric finally obtained in Comparative Example 1 is level 2.5; the anti-pilling effect of the bird's nest cloth fabric finally obtained in Comparative Example 2 is level 2.5; the anti-pilling effect of the bird's nest cloth fabric finally obtained in Comparative Example 3 is level 2.

[0067] (2) Antistatic effect testing

[0068] Test according to GB / T12703-1991 "Test Method for Electrostatic Test of Textiles": In an environment with a temperature of 20±5℃ and a humidity of 30-40%, after washing 100 times, test the average surface charge density of the fabric.

[0069] After testing, the average charge surface density of the bird's nest fabric finally obtained in Example 1 is 5 μc / m 2 The average charge surface density of the bird's nest fabric finally obtained in Comparative Example 1 is 5.1 μc / m 2 The average charge surface density of the bird's nest fabric finally obtained in Comparative Example 2 is 8 μc / m 2 The average charge surface density of the bird's nest fabric finally obtained in comparative example 3 is 5.3 μc / m 2 .
