Embodiment 1

[0043]Fabric name: polyester crepe; fabric specification: raw material is polyester 111dtex(DTY)×111dtex(DTY), density is 256×256 / 10cm, weight is 142g / m 2 .

[0044] The cold transfer printing method of polyester crepe disperse dyes is a production process using cold transfer printing. First, the base paper is coated with a release agent on the printing side of the base paper by a coating machine, and the printing machine uses disperse dye ink to print cold transfer printing paper, and then the cold transfer printing paper and polyester crepe fabric are sent into the cold transfer printing paper together. machine. After the polyester crepe fabric is treated with the pretreatment agent of the pretreatment device of the cold transfer printing machine, it is closely bonded with the cold transfer printing paper and transferred through the cold transfer printing device to make a polyester crepe printed fabric. The polyester crepe printed fabric is steam-fixed or baked to fix the ...

[0060] Fabric name: Polyester cotton poplin; Fabric specification: Raw material is 45 S ×45 S Polyester cotton (T / C, 65 / 35), density 433×229 / 10cm.

[0061] The production process of polyester-cotton poplin disperse dye cold transfer printing is shown in Example 1, and will not be described in detail. in:

[0062] Disperse dye ink:

[0063] The total weight of the disperse dye ink suitable for polyester-cotton poplin cold transfer printing is 100%, and each component by weight percentage is as follows:

[0064] Macromolecular disperse dyes account for 15%, and C.I. disperse blue 14 is selected,

[0065] The paste accounts for 7%, and the oxidized starch is selected,

[0066] The dispersing agent accounts for 3%, selects NNO dispersing agent (sodium methylene bistethylate sulfonate) for use,

[0067] Deionization accounted for 75%.

[0068] First add 3% by weight of NNO dispersant to an appropriate amount of warm water, then add 15% by weight of C.I. Add oxidized starch ...

Embodiment 3

[0077] Fabric name: polyester / cotton elastic twill; fabric specification: raw material is polyester and (cotton + spandex fiber), [25d×(16 S +40d)], the density is 433×229 / 10cm.

[0078] The production process of polyester / cotton elastic twill disperse dye cold transfer printing is shown in Example 1, and will not be described in detail. in:

[0079] Disperse dye ink:

[0080] The total weight of the disperse dye ink suitable for polyester / cotton elastic twill fabric cold transfer printing is 100%, and each component by weight percentage is as follows:

[0081] Macromolecular disperse dyes account for 40%, and C.I. Fei Huang and Bright Yellow are selected.

[0082] Paste accounts for 10%, choose guar gum paste

[0083] Dispersant accounts for 4%, select OT-75 dispersant,

[0084] Deionization accounted for 46%. .

[0085] First add 4% by weight of OT-75 dispersant to an appropriate amount of warm water, then add 40% by weight of C.I. Dispersed Feihuang and Bright Yellow...

Abstract

A cold transfer decal process of disperse dyes comprises processes including body paper precoating, dispersing dye based ink printing, pretreatment of fabric, cold transferring paper and fabric driving fit transferring, printed fabric fixation, washing and sizing. The printing ink is composed of macromolecule disperse dyes, thickener, dispersing agent and deionized water. The pretreatment agent is composed of binding agent, slip agent, emulsifying agent, defoaming agent and deionized water. The cold transfer decal process of disperse dyes enables the environment of manufacturing shops to meet environmental protection requirements, and printed fabric end products do not contain residues including methyl alcohol, butyl alcohol and the like.

Description

technical field [0001] The invention relates to the printing and dyeing industry in the textile industry, in particular to a cold transfer printing method of disperse dyes. At present domestic and international disperse dye transfer printing all adopt thermal transfer printing method, the present invention is to change this thermal transfer printing method, adopt cold transfer printing method, make the quality of disperse dye transfer printing be improved, more accord with the requirement of environmental protection. Background technique [0002] Transfer printing is to use the printing method to print the appropriate dye ink first, print the pattern or text to be printed on special paper, and print it into a transfer printing paper; then print the dye on the transfer printing paper One side is close to the printed fabric, through the transfer printing machine, under the action of heat and pressure (sublimation method) or solvent and pressure (wet method) of the transfer pri...
