Embodiment Construction

[0023] The environmentally friendly heat transfer ink of the present invention includes the following components: pigment paste, water-soluble organic solvent, styrene-acrylic polymer emulsion with a glass transition temperature of less than 0°C, surfactant and water, preferably, 100 parts by total weight In total, the environmentally friendly heat transfer ink includes 25-30 parts of pigment paste, 10-20 parts of water-soluble organic solvent, 15 parts of styrene-acrylic polymer emulsion, 0-2 parts of surfactant and the balance Of water. More preferably, the particle size of the pigment paste is preferably D50≤200nm and D99≤300nm. More preferably, the styrene-acrylic polymer emulsion is a water-dispersed styrene acrylic resin, and the water-soluble organic solvent is one or more of diethylene glycol, propylene glycol and glycerol. The environmentally friendly heat transfer ink also includes surfactants and antibacterial agents, wherein the surfactant is one or more of acetyle...

Abstract

The invention provides environment-friendly pyrography ink, a PET film heat transfer printing method and application of the environment-friendly pyrography ink and the PET film heat transfer printingmethod. The environment-friendly pyrography ink comprises pigment color paste, a water-soluble organic solvent, a surfactant and a styrene-acrylic polymer emulsion with the glass transition temperature of less than 0 DEG C, the ink is printed on a PET film through an ink-jet printer; the PET film is used for carrying out a heat transfer printing process on pure cotton or cotton blended fabric; thestyrene-acrylic polymer emulsion can form a film layer with good adhesive force and tensile strength on the PET film; the permeation phenomenon of the water-based pigment ink on the PET film is improved; the styrene-acrylic polymer emulsion is low in glass transition temperature, so that the styrene-acrylic polymer emulsion is in a soft state during heat transfer printing, ink is more easily transferred to the fabric from the PET film, the adhesive force of printed patterns is enhanced, and the friction resistance and the color fastness to washing of the printed patterns on the fabric are effectively improved.

Description

Technical field [0001] The invention relates to the field of textile printing, in particular to an environment-friendly heat transfer ink, a PET film thermal transfer method and its application. Background technique [0002] With the continuous development of textile inkjet printing, in addition to the conventional inkjet printing on white cloth, people began to print colorful printing patterns on dark fabrics. Due to the color superposition, the color printing effect is always covered by the dark color, so that the color pattern on the dark cloth is always dim, even invisible. In order to be able to print color patterns on dark fabrics, two solutions are currently used. They are: 1) Directly print white ink on the dark fabric to cover the dark color, and then print the color pattern on the white ink; 2 ) Use the silk screen method to print a layer of white glue on the dark fabric that needs to be printed, and then use the precision printing method to print the color pattern on ...
