Problems solved by technology

Furthermore, especially the terminal hydroxyl groups of the two substances have strong activity, and a large amount of reactive dyes will also be consumed during cellulose fiber printing.
Therefore, using polyethylene oxide or polypropylene oxide as the base material will combine a large amount of dyes, resulting in low dyeing rate, light color, and a lot of waste of dyes, and finally enters the waste water during washing, causing pollution
[0008] In addition, in the thermal transfer printing method proposed in Chinese patent 201010519572.2, the fabric to be transferred must be pre-treated with a water-absorbing agent and an acid agent (or alkali agent), and the process is cumbersome.

Embodiment 1

[0038] Dissolve hydroxypropyl methylcellulose in water to make a 10% (w / w) solution, add 2% baking soda, 6% urea, apply it on 100 grams of white paper with a knife coater, and dry it , rewinding for later use. 20% reactive black kn-b, 5% sodium alginate, and 75% water are used to make ink according to the weight percentage. The pattern is selected, and the pattern is printed with a rotary screen printing machine, and then rolled. Lay the above-mentioned printed transfer paper with the cotton knitted fabric, and enter the roller heat transfer machine together, adjust the temperature to 120°C, and adjust the pressure to 15Kg / cm 2 , After transfer printing, wet the fabric and the transfer paper on the reverse side, and then wrap it with plastic film to prevent water loss, put it in a constant temperature room at 15°C, and store it in a cold stack for 16 hours. Finally, tear off the backing paper and wash it with water. process to complete the transfer printing.

Embodiment 2

[0049] Mix methylcellulose and hydroxypropylcellulose in a weight ratio of 5:1, dissolve them with ethanol and water 1:1 (V / V), make a 30% (w / w) solution, add 7% glycerol, 2% citric acid is coated on the BOPP film with a gravure printing machine, dried, and rolled up for later use. Then 0.5% of weak acid red B, 10% of polyvinyl acetal resin, and 89.5% of methyl alcohol are made into ink by weight percentage, and the pattern is selected, and after the pattern is printed with a gravure printing machine, it is wound up. Lay the above printed transfer film with the cut silk fabric, put them into the flatbed transfer machine together, adjust the temperature to 150°C, and adjust the pressure to 25Kg / cm 2 , After transfer printing, put the fabric together with the transfer film in a steamer for 45 minutes at a temperature of 102°C. Finally, the transfer film is torn off, and post-treatment processes such as water washing are performed to complete the transfer printing.

Embodiment 3

[0060] Dissolve hydroxypropyl methylcellulose in a mixed solution of 40% methanol and 60% water by volume to make a 20% (w / w) solution, apply it on a nylon film with a gravure printing machine, dry it, and roll it up for later use . Disperse Red 2BL 5%, carboxymethyl starch 5%, water 90%, are made into ink by weight percentage again, select pattern, after printing pattern with flat screen printing machine, wind up. Lay the above printed transfer film with the polyester knitted fabric, and enter the roller heat transfer machine together, adjust the temperature to 120°C, and adjust the pressure to 30Kg / cm 2 , after transfer printing, tear off the nylon film, bake in an oven at 230°C for 3 minutes, wash with water, and set the shape to complete the transfer printing.

[0061] Through the test, the various fastness indexes of the pattern after printing are shown in Table 5.

Abstract

The invention discloses a method for transferring patterns of a fabric. The method comprises the following steps of: dissolving a polymer substance in water or a mixed solution of water and an organic solvent, coating paper or a plastic film, drying, and coiling for later use; printing on the paper or the plastic film with dye-based ink or dye-based water ink to obtain transfer paper or a transfer film; jointing the printing surface of the transfer paper or the transfer film with a fabric to be transferred, putting the transfer paper or the transfer film and the fabric into a transfer machine, heating and pressurizing to realize printing; stripping the transfer paper or the transfer film and fixing a dye; or fixing the dye and then stripping the transfer paper or the transfer film; and washing the fabric with water and sizing to finish transferring. By adopting the transferring method disclosed by the invention, the inherent transfer thought is broken through, the humidification procedure is eliminated, the processing time is saved, the production cost is lowered, and the printing difficulty is lowered.

Description

technical field [0001] The invention relates to a fabric printing and dyeing method, in particular to a fabric pattern transfer method. Background technique [0002] The traditional textile thermal transfer printing method began in the late 1960s. It is a printing method that first prints easily sublimable disperse dyes on the transfer base paper, and then transfers the disperse dyes to the fabric by hot pressing to form a pattern. It has the advantages of realistic flower pattern, simple process, less discharge of three wastes and so on. It is only suitable for printing on polyester fabrics and does not work well on nylon, acrylic, and natural fiber fabrics. [0003] In order to realize the transfer printing of natural fibers, the wet transfer printing of reactive dyes and acid dyes has attracted the attention of many printing and dyeing workers at home and abroad. Patent No. 200410041034.1 and Patent No. 200510026661.2 each disclose a wet transfer method for natural fib...
