Embodiment 1

[0031] Step 1: Evenly disperse polyester hot melt adhesive powder with a mesh number of 200 in water to form a suspension, then add sodium alginate to the above suspension to adjust the viscosity of the solution to 2000mPa.s, finally add sodium carbonate and urea, and stir Dissolve the sodium carbonate and urea evenly to prepare the paste for dry transfer printing. In this paste, the content of polyester hot melt adhesive is 10% (w / w), the content of sodium alginate is 6% (w / w), the content of sodium carbonate is 3% (w / w), and the content of urea is 7% %(w / w). The percentages in the examples mean the mass ratio of this component to the total amount of the paste.

[0032] Step 2: Coating the printing paste prepared above on the paper surface with a density of 45 g / cm2. The coating thickness is 0.4mm, the drying temperature is 60°C, and the drying time is 20 minutes; the calendering temperature is 25°C, the calendering roll speed is 10 rpm, and the calendering pressure is 0.5M...

[0037] Step 1: Evenly disperse polyurethane hot melt adhesive powder with a mesh number of 100 in water to form a suspension, then add starch ether to the above suspension to adjust the viscosity of the solution to 3000mPa.s, finally add trichloroacetic acid and glycerin, and stir well Fully dissolve the trichloroacetic acid and glycerin to prepare the paste for dry transfer printing. In this paste, the content of polyurethane hot melt adhesive is 8% (w / w), the content of starch ether is 12% (w / w), the content of trichloroacetic acid is 5% (w / w), and the content of glycerin is 10% (w / w).

[0038] Step 2: coating the printing paste prepared above on the surface of the PET film. The coating thickness is 0.3mm, the drying temperature is 50°C, and the drying time is 30 minutes; the calendering temperature is 25°C, the calendering roll speed is 20 rpm, and the calendering pressure is 0.3Mpa.

[0039] Step 3: Print the acid dye ink on the surface of the above-prepared film by gravur...

Embodiment 3

[0043] Step 1: Evenly disperse the polyamide hot-melt adhesive powder with a mesh number of 300 and the polyester hot-melt adhesive powder with a mesh number of 200 in water to form a suspension, and then add sodium carboxymethylcellulose (belonging to Cellulose ether) to adjust the viscosity of the solution to 3500mPa.s, finally add sodium trichloroacetate and urea, stir evenly to fully dissolve the sodium trichloroacetate and urea, and prepare a paste for dry transfer printing. In this paste, polyamide hot melt adhesive content is 5% (w / w), polyester hot melt adhesive content is 5% (w / w), carboxymethyl cellulose sodium content is 3% (w / w ), the content of sodium trichloroacetate is 4% (w / w), and the content of urea is 9% (w / w).

[0044] Step 2: Coating the printing paste prepared above on the paper surface with a density of 44 g / cm2. The coating thickness is 0.5mm, the drying temperature is 70°C, and the drying time is 20 minutes; the calendering temperature is 25°C, the ca...

Abstract

The invention relates to a dry-type transfer-printed textile and a preparation method of the dry-type transfer-printed textile. The method comprises the following steps: uniformly dispersing a water-dispersible hot melt adhesive into water so as to form a suspension; adding a printing thickener so as to regulate the viscosity of the suspension; adding printing auxiliaries such as acid, alkali and a hygroscopic agent according to the used dye, so as to prepare printing paste; coating a paper sheet or s film by use of the printing paste; drying and calendering, so as to obtain a paper sheet or film with the coating surface; performing printing treatment on the paper sheet or the film by use of a dye, so as to prepare transfer paper or a transfer film; hot-pressing and laminating the transfer paper or transfer film and a to-be-printed textile; performing color fixing, then stripping off the transfer paper or transfer film, and washing and sizing the textile after the color fixing, so as to obtain the printed textile. According to the printing method provided by the invention, wetting treatment of the textile is omitted, and transfer printing can be directly performed on the dry textile or a garment, so that the definition of printed patterns and the transfer stability of the dye are ensured; meanwhile, the operation sequence is simplified, emission of waste water of the printing and dyeing industry can be reduced, and the preparation method is beneficial to energy conservation and environment protection.

Description

technical field [0001] The invention relates to a textile transfer printing method, which belongs to the technical field of textile dyeing and finishing. Background technique [0002] The earliest dry transfer printing paper for textiles is widely used in the printing of polyester fabrics. This kind of printing is the well-known disperse dye sublimation transfer printing. Under high temperature and pressure, the pattern is transferred to the fabric by using the sublimation performance of disperse dyes. This printing method has the advantages of clear layers of printing patterns, strong three-dimensional effect, short process flow and strong processing flexibility. Once it came out, it attracted wide attention from people in the industry. [0003] Yet above-mentioned method has an obvious limitation, and it is only suitable for this kind of polyester synthetic fiber fabric with thermoplasticity, is not suitable for this kind of natural fiber fabric of cotton, real silk. The...
