Embodiment 1

[0024] The invention proposes a one-way penetrant for the pretreatment of digital printing of natural fiber fabrics. The one-way penetrant consists of penetrant A, penetrant B and solvent E.

[0025] Wherein, the organic molecular structure of the penetrant A is:

[0026]

[0027] The organic molecular structure of the penetrant B is:

[0028]

[0029] The solvent E is an aliphatic alkane with an atom number C of 5-8.

[0030] Mix penetrant A and penetrant B at a ratio of 1-9:9-1, dissolve in solvent E that is 2-10 times the dose of penetrant A and penetrant B, and obtain a one-way osmosis that can be used in production agent.

Embodiment 2

[0032] This embodiment is further optimized on the basis of the above-mentioned embodiments, and the same parts as the aforementioned technical solutions will not be repeated here. Further, in order to better realize the present invention, the following setting method is adopted in particular: the one-way penetrating agent It is suitable for the pre-printing treatment of cotton, linen, mulberry silk and other natural fiber fabrics; the one-way penetrant is preferably added to the slurry formula for use in the pre-printing treatment.

[0033] The method of using the one-way penetrating agent in the pretreatment of digital printing of natural fiber fabrics is as follows: use normal temperature to uniformly stir the slurry into a paste according to the set formula on the pulping machine, and initially mix other components of the slurry at a high speed of 2300-2400 (Preferably 2400) rev / min and low speed 1400~1500 (preferably 1500) rev / min alternately make pulp for 25-30 (preferabl...

Embodiment 3

[0035] This embodiment is further optimized on the basis of any of the above-mentioned embodiments, and the same parts as the aforementioned technical solutions will not be repeated here. Further, in order to better realize the present invention, the following setting method is adopted in particular: the one-way The penetrant improves the penetration characteristics of the jet printing ink to the natural fiber fabric by controlling the fabric receiving and limiting the amount and method of jet printing ink immersion, so that the surface of the fabric slurry after sizing and drying has a certain degree of hydrophobicity, which indirectly hinders the hydrophilicity. The active ink diffuses around the surface of the fabric without affecting the natural penetration of the active ink into the interior of the fabric by gravity, thereby improving the dyeing rate of the fabric.

Abstract

The invention discloses a one-way penetrating agent for digital printing pretreatment of a natural fiber fabric. The one-way penetrating agent consists of a penetrating agent A, a penetrating agent Band a solvent E, wherein the solvent E is fatty alkane with the atomic number C of 5-8, the penetrating agent A and the penetrating agent B are mixed according to the proportion of 1-9: 9-1 and dissolved in the solvent E with the dosage being 2-10 times that of the penetrating agent A and the penetrating agent B, and the one-way penetrating agent capable of being produced and used is obtained; andthe one-way penetrating agent can be added into a slurry formula for use, and the one-way penetrating agent is suitable for ink-jet printing pretreatment of natural fiber fabrics such as cotton, hempand mulberry silk. By adopting the one-way penetrating agent, the jet printing ink can be prevented from diffusing to the periphery of the surface of the fabric without influencing the longitudinal natural permeation of the fabric, so that the permeation characteristic of the jet printing ink to the natural fiber fabric is indirectly improved, and the K / S depth value and the color clarity of thejet printing color of the natural fiber fabric are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a one-way penetrating agent used for pretreatment of digital printing of natural fiber fabrics. Background technique [0002] Digital printing of natural fiber fabrics is a branch of the field of textile printing, and paddle feeding is an indispensable pre-printing process in its production process. The existing pretreatment slurry system is a strong hydrophilic material with excellent compatibility with ink, which is conducive to the diffusion of inkjet printing, but indirectly affects the downward penetration of ink into the fabric, making the front and back of the fabric pattern The color difference is very large, and it is easy to appear the thread turning phenomenon, and the printing accuracy of the flower pattern is often affected by the excessive diffusion of the ink. Contents of the invention [0003] The purpose of the present invention is to desig...
