Description

A kind of 3D 3-D digital stamp cloth technique

Technical field

The present invention relates to a kind of stamp cloth technique, especially relate to a kind of 3D 3-D digital stamp cloth technique.

Background technology

Digital printing technology is the product advanced technologies such as precision optical machinery, computer and optoelectronic integration being carried out merging, and is an important breakthrough to Conventional decal technology.Digital printing technology breaks traditions stamp production tricks and spend back the restriction of length, digital pattern is adopted to carry out colour measuring & colour matching, spray printing through computer, thus making the color of digit printing product can reach 1,670 ten thousand kinds, digit printing printing effect, pattern level, 3D stereoeffect, colour system etc. reach perfect effect true to nature.

3D stereoeffect requires harsher for the Dry Sack of pattern, color boundaries definition, profile sense, in order to make fabric have better painted and fixation, preventing imbibition, therefore must carry out suitable preliminary treatment to fabric, afterwards could spray printing.Suitable slurry not only can make fabric face smooth, the more important thing is the space can blocked between fiber, stops dyestuff along capillary diffusion simultaneously.But the interpolation of thickener, auxiliary agent also can have an impact to the degree of fixation of dyestuff and fabric face tinctorial yield in slurry.

Summary of the invention

For solving in prior art, the problem that imbibition, degree of fixation and tinctorial yield that polyester cotton digit printing technique easily occurs are low, the object of the present invention is to provide a kind of 3D 3-D digital stamp cloth technique, it can effectively prevent color imbibition, and improves dye fixing rate and tinctorial yield.

The technical scheme that the present invention takes for achieving the above object is, a kind of 3D 3-D digital stamp cloth technique, comprise the following steps, textile sizing, oven dry, spray printing, decatize, cold wash, hot water wash, soap, dry, it is characterized in that: described fabric is polyester-cotton fabric, can be 50% wash/50% COTTON FABRIC further.

Described textile sizing technique adopts 50-90 eye mesh screen to scrape slurry 4-7 time, scrapes in slurry process and will note evenly being applied to fabric, can not make the curved and skew of weft of fabric generation latitude.

Slurry in described textile sizing technique consists of (percentage by weight): tamarind gum 2-4%, guar gum 2-6%, rare earth chloride 2.5-3%, sodium chloride 1-2%, carboxymethyl cellulose 0.5-1%, diatomite 2-4%, and surplus is water.

The preparation method of described slurry is: take raw material by formula, gets part water stirring and dissolving tamarind gum and guar gum, adds rare earth chloride, sodium chloride, carboxymethyl cellulose, diatomite respectively subsequently, stir while adding, and finally adds residue water and adjusts rare.

Described decatize is vapor (steam) temperature 104 ~ 110 DEG C, and steaming time is 10-15 minute.

The advantage that the present invention has and beneficial effect are:

(1) tamarind gum in amount ranges of the present invention and guar gum and carboxymethyl cellulose are while having obvious anti-imbibition effect, its imbibition rate vary stable near critical concentration value can also be made, synergy, can effectively prevent pigment from producing diffusion with the capillary motion between fibre bundle, thus cause profile unintelligible, the indefinite problem in border, and high colour-fast rate can be reached and obtain chromatic effect while there is better anti-imbibition effect.

(2) discovery that applicant is pleasantly surprised, in system of the present invention, can promote the adding of certain content rare earth chloride the degree of fixation improving dyestuff.

(3) slurry in present invention process, while guarantee high colour-fast rate and tinctorial yield, abandons the use of urea in traditional handicraft, realizes the printing technology without urea completely, reaches the plan that ammonia nitrogen reduces discharging, and realizes green production.

(4) raw material sources of the present invention are extensive, and cost is lower, and preparation method is simple, are easy to operation.

(5) 3D digit printing product colour of the present invention is gorgeous, and clear-cut, third dimension is strong.

Detailed description of the invention

50% is selected to wash/50% COTTON FABRIC, the slurry of following embodiment and comparative example is carried out starching process, to the pattern spray printing of 3D effect process be carried out on fabric after oven dry, eventually pass vapour steaming colour fixing, cold wash, hot water wash, soap and dry, obtain third dimension strong, color is gorgeous, sharply marginated 3D digit printing product.

Embodiment 1:

Slurry consists of (percentage by weight): tamarind gum 2%, guar gum 6%, rare earth chloride 2.5%, sodium chloride 1%, carboxymethyl cellulose 0.8%, diatomite 3%, and surplus is water.

Embodiment 2:

Slurry consists of (percentage by weight): tamarind gum 4%, guar gum 4%, rare earth chloride 3%, sodium chloride 1.5%, carboxymethyl cellulose 0.5%, diatomite 2%, and surplus is water.

Embodiment 3:

Slurry consists of (percentage by weight): tamarind gum 3.6%, guar gum 5%, rare earth chloride 2.8%, sodium chloride 2%, carboxymethyl cellulose 1%, diatomite 4%, and surplus is water.

Comparative example 1:

Commercially available SM001 type digit printing slurry is adopted to carry out contrast test.

Comparative example 2:

Form identical with embodiment 1 raw material, difference is only not add rare earth chloride.

Comparative example 3:

Form identical with embodiment 1 raw material, difference is only that rare earth chloride content is 5%.

Method of testing:

(1) test of imbibition degree

Design round dot pattern, enters computer by scanner by pattern scan, then measures the area of pattern with Image software.Imbibition degree R is calculated according to formula (1).

$R=\frac{S^{\′}-S}{S}\×100\%---\left(1\right)$

In formula (1): S be design decalcomania area, S ' for spray printing complete after pattern area.

(2) mensuration of tinctorial yield K/S

Datacolor SF600 colour matching instrument is adopted to measure.

(3) mensuration of degree of fixation

With reference to GB/T 2391-2006.

Test result

Table 1 imbibition degree R, degree of fixation and K/S value

	Imbibition degree R/%	Degree of fixation/%	K/S value
				Embodiment 1	8.71	95.87	16.66
