Technical field

The present invention relates to fabric digital printing technology fields, and in particular to a kind of digital printing method of fleece fabrics.

Background technique

The technical process of digit printing has the reactive dye used to determine, starching, print before generally including fabric pretreatment, printing Drying, decatize, washing drying after preceding drying, ink-jet printed, print.Compared with conventional dyeing, digital printing process are simple, without big Measure waste water containing dyestuff to generate, but defect is: the color of digit printing is not bright-coloured enough, on color fastness especially fastness to wet rubbing It needs to improve.

Improved technical solution opens two sulphur of cashmere epicuticula using TCEP as disclosed in CN106544909A Key, and osmotic agent solution dyestuff and swollen fiber are used, it helps dyestuff to permeate from fiber surface to fibrous inside, changes in conjunction with above-mentioned Steam temperature can be suitably reduced into scheme, shortens steaming time, reduce damage of the decatize for cashmere fiber.Above-mentioned improvement project Facilitate the dye-uptake of improvement digit printing, but color fastness is improved unobvious.

Summary of the invention

It is an object of the invention to overcome defect existing in the prior art, a kind of digit printing side of fleece fabrics is provided Method, dyestuff and fiber form firm associative key, improve the color fastness of fleece fabrics.

To achieve the above object, the technical solution of the present invention is as follows: a kind of digital printing method of fleece fabrics, feature exist In, comprising the following steps:

S1: the low-temperature plasma processing of fleece fabrics；

S2: configuring digital ink-jet printed slurry, and main group of digital ink-jet printed slurry becomes thickener, urea, sodium sulphate, sulphur Sour ammonium, water-soluble organic acid lanthanum or organic acid lanthanum salt, glycerol and water；

S3: it by fleece fabrics obtained by concentrator sieve starching obtained by S2 to S1, dries；

S4: using the ink-jet printed processing of fleece fabrics of the active ink to starching, through preliminary drying, decatize, soap, wash, low temperature dries It is dry, obtain stamp fleece fabrics.

Preferred technical solution is the low-temperature plasma treatment process parameter of fleece fabrics in S1 are as follows: voltage 200~ 220V, 10~15s of time, processing atmosphere are argon gas.

Preferred technical solution is that organic acid lanthanum is lanthanum acetate or citric acid lanthanum salt, is had in digital ink-jet printed slurry The weight percent of machine acid lanthanum is 0.1~2%.

Preferred technical solution is the composition of digital ink-jet printed slurry are as follows: sodium alginate etherification starch paste 2~2.5%, Urea 5~10%, sodium sulphate 7~10%, glycerol 3~6%, ammonium sulfate 2~3%, organic acid lanthanum 0.5~2% and surplus water.

Preferred technical solution is that preliminary drying temperature is 72~82 DEG C in S4, and preliminary drying time is 13~19min；Fabric decatize Temperature is 100~105 DEG C, and steaming time is 15~20min.

Preferred technical solution is that temperature of soaping in S4 is 80~85 DEG C, and the concentration of soap flakes is 2~2.5g/ in liquid of soaping L, time of soaping are 30~50min.

The advantages and beneficial effects of the present invention are:

The digital printing method of the fleece fabrics handles the scale layer for destroying cashmere surface by low-temperature plasma, improves fiber Hygroscopicity, so that the cashmere fiber scale layer for applying slurry tends to be soft, water-soluble organic acid lanthanum or organic acid lanthanum salt are helped In promoting fiber and dye molecule to form firm associative key, the color yield and color fastness of fleece fabrics are improved.

Specific embodiment

With reference to embodiment, the specific embodiment of the present invention is further described.Following embodiment is only used for more Add and clearly demonstrate technical solution of the present invention, and not intended to limit the protection scope of the present invention.
