Problems solved by technology

[0004] Although the pattern printed by this method is bright in color, its color fastness is poor, and it will fade after being exposed to light, washing, etc., and the color of the pattern will become lighter, thus affecting its wearing effect.

Embodiment 1

[0014] First prepare the ink for transfer printing: mix 50% disperse dye, 42% methanol, 3% polyvinyl butyral, and 5% stabilizer bishydroxy compound metal oxide, and stir evenly to make The ink is printed on the transfer paper according to a certain flower shape, and the double hydroxyl composite metal oxide is selected from the hydrotalcite Mg 6 Al 2 (OH) 16 CO 3 4H 2 O powder.

[0015] Then mix polyethylene oxide with water at a ratio of 1:1000, immerse the textile cloth in the mixture for 3 seconds, and then take it out to dry. Overlap the patterned side of the transfer paper with the fabric, apply high temperature heat press at 220°C for about 30 seconds, then the disperse dye sublimates into a gaseous state, and transfers from the paper to the fabric.

Embodiment 2

[0017] First prepare the ink for transfer printing: mix 60% disperse dye, 28% methanol, 2% polyvinyl butyral, and 10% stabilizer bishydroxy compound metal oxide, and stir evenly to make The ink is printed on the transfer paper according to a certain flower shape, and the double hydroxyl composite metal oxide is selected from the hydrotalcite Mg 6 Al 2 (OH) 16 CO 3 4H 2 O powder.

[0018] Then mix polyethylene oxide with water at a ratio of 1:5000, immerse the textile fabric in the mixture for 5 seconds, and then take it out to dry. Overlap the patterned side of the transfer paper with the textile, and apply high temperature heat press at 220°C for about 40 seconds, then the disperse dye sublimates into a gaseous state and transfers from the paper to the fabric.

Embodiment 3

[0020] First prepare the ink for transfer printing: mix 70% disperse dye, 14% methanol, 1% polyvinyl butyral, and 15% stabilizer bishydroxy compound metal oxide, and stir evenly to make The ink is printed on the transfer paper according to a certain flower shape, and the double hydroxyl composite metal oxide is selected from the hydrotalcite Mg 6 Al 2 (OH) 16 CO 3 4H 2 O powder.

[0021] Then mix polyethylene oxide with water at a ratio of 1:10000, immerse the textile cloth in the mixture for 8 seconds, and then take it out to dry. Overlap the patterned side of the transfer paper with the fabric, apply high temperature heat press at 220°C for about 60 seconds, then the disperse dye sublimates into a gaseous state, and transfers from the paper to the fabric.

Abstract

The invention provides a high colorfastness transfer printing method. An prepared transfer printing ink comprises the following components in percentage by mass: 50-70% of disperse dye, 14-42% of methanol and/or isobutanol, 5-15% of polyvinyl butyral and 1-3% of stabilizing agent double-hydroxy composite metal oxide; and the transfer printing method comprises the following steps of: first, wetting a fabric to be printed by using a polyoxyethylene or polypropylene oxide aqueous solution; and then carrying out transfer printing on the fabric to be printed. The high colorfastness transfer printing method provided by the invention has the advantages of simple process, low cost, strong cohesiveness between a pattern and a fabric after printing and durability; and high colorfastness can be kept under conditions of water washing, Illumination, heating and so on.

Description

technical field [0001] The invention relates to the technical field of transfer printing, in particular to an ink for transfer printing and a method for improving the color fastness of transfer printing. Background technique [0002] Color fastness, also known as color fastness and color fastness, refers to the resistance of the color of textiles to various effects during processing and use. Textiles will be subjected to various external effects such as light, washing, ironing, sweat stains, friction and chemicals during their use. Some printed and dyed textiles also undergo special finishing processes, such as resin finishing, flame-retardant finishing, sand washing, grinding, etc. Wool, etc., which requires the color of printed and dyed textiles to maintain a certain degree of fastness. Whether the color fastness is good or bad is directly related to the health and safety of the human body. When a product with poor color fastness encounters rain or sweat during wearing, t...
