Abstract

The present invention relates to a transfer printing method for a real silk fabric. A real silk fabric is first preprocessed, then, the real silk fabric is placed on transfer printing paper to be pressed in a heating mode or ironed, and patterns are printed on the real silk fabric. Expanding agents of halogenation salt, or organic acid, and a derivate of the organic acid, or polyatomic alcohol, and a perylene derivative of the polyatomic alcohol or a mixture of alcohol and/or acid are added in the preprocessing liquid of the real silk fabric, and a cationic surfactant or a softening agent using the cationic surfactant as a main component is also added into the preprocessing liquid. A low temperature type disperse dye is used as a dye. The soaping fastness of the real silk fabric can reach 4 to 5 grades, and the original styles of real silk are kept. A raw material is easy to obtain, and a process is simple and convenient. The present invention can be applied to the existing transfer printing equipment, and the existing or new designed pattern transfer printing paper.

Description

A kind of method for transfer printing of real silk fabric

The present invention relates to a kind of usefulness and give finishing agent processing real silk fabric, use DISPERSE DYES to carry out the method for transfer printing.

Transfer printing is a kind of of textile printing process, have save time, the advantage of laborsaving, pollution-free, small investment, instant effect, it is that fabric is placed on the transfer paper that is printed on design, by heat treatment, make pattern transfer on the paper to fabric, but this method is very poor to the printing effect of natural fabric, and dye-uptake is low.For improving effect, still need natural fabric is carried out modification.Data is introduced, and has three kinds of ways at present: graft crosslinking, resin spray process, its expansion.Graft copolymerization is to make chemical group and fabric construction crosslinked, and reaction process complexity, cost height, natural fabric can lose original good style.The resin spraying method is to apply one deck chemical substance at fabric face, and this also can influence the good characteristic of natural fabric.The method of said its expansion is to utilize chemical substance that fabric is expanded, and fabric easily contacts with dyestuff and the method that dyes, and swelling agent has and stays on a small quantity in fabric, and we think than the first two class methods for good.Japan Patent: 62-250288 has reported that employing polyalcohol and derivative thereof make swelling agent, uses dyestuff:

(alkyl of R:1～3 carbon atom) carries out the method for transfer printing to natural silk and silk with synthetic fibre mixed fabric, treatment fluid contains swelling agent 10～30%, can obtain the identical printed silk of tow sides flower type, effect is fine, but through our checking, the fabric soaping fastness of its printing is low, has only 3 grades, some weakness of natural fabric does not improve, and swelling agent and processing method thereof are still needed and further improved and raising.

The present invention is for improving above-mentioned weak point, proposed the treatment fluid that gives that a kind of use comprises swelling agent and cationic surfactant and handled real silk fabric, uses DISPERSE DYES to carry out the method for transfer printing.

The present invention can be realized by following method, and real silk fabric earlier with giving the method that treatment fluid is handled, is given treatment fluid and is made up of three parts:

1, swelling agent: as the halide salt of calcium, strontium, lithium, zinc, or organic acid and derivative thereof, or polyalcohol and derivative thereof, or the mixture of above-mentioned acid and/or alcohol;

2, cationic surfactant, or be the softener of main component with it;

3, running water or deionized water or distilled water.

Each percentage by weight cooperation ratio of forming is:

Component 1:1～50%; Component 2:1～40%; Component 3: supply 100%.

Above-mentioned finishing agent and real silk fabric are made into bath raio is: 20: 1～50: 1, under 15～50 ℃, one soaks one rolled, and the hydraulic fluid rate is: 60～100%, under＜100 ℃, carry out heated-air drying then, and be 5～40 minutes drying time.

The present invention specifies as follows: according to our research, during the real silk fabric transfer printing, used dyestuff should be the low form DISPERSE DYES in its transfer printing paper, when selecting used DISPERSE DYES, should meet following actual conditions:

Molecular weight: 230～370

Vapour pressure (200 ℃): 5 * 10 ^-2～5 * 10 ^-8Millibar

Diffusion coefficient: (200 ℃): 2.2 * 10 ^-8～6.0 * 10 ^-8Centimetre ²/ second

Sublimation temperature: 150～230 ℃ as: Disperse Yellow RGFL:

Perhaps: 8GFF, 4G, 3GE.

Disperse Red 3B:

Perhaps: FB.

Disperse Blue 2BLN:

Perhaps: FBL.But use the various required colors of above-mentioned dyestuff furnishing.Be to guarantee the dyestuff dye-uptake, must use swelling agent, and desire improves COLOR FASTNESS and fabric sofetening, elasticity, must add cationic surfactant simultaneously or be the softener of main component with it.According to our experiment screening, its swelling agent is chosen the class in following three classes:

(1) halide salt refers to chlorate or Bromide or the iodized salt or the nitrate of calcium, strontium, lithium, zinc, preferred chlorate.Use wherein a kind of;

The organic acid of (2) 1～10 carbon atoms and ester class thereof, amide derivatives, the preferred use: acetate, acrylamide, urea.Use wherein a kind of;

(3) polyalcohol and derivative thereof reasonablely are: 1～4 carbon atom polyalcohol and derivative thereof, preferred ethylene glycol, glycerol, polyvinyl alcohol, triethylene glycol, polyethylene glycol, POLYPROPYLENE GLYCOL.Use wherein a kind of.

Experiment shows, cationic surfactant and with its be the softener of main component through screening, can use the class in following three classes:

(1) open chain fatty amine salt type, primary, the second month in a season, uncle, quaternary amine all can.Use wherein a kind of;

(2) lipophilic group by the amine salt that middle key forms as Suo Luoming (Soromine) structure is:

Sa Paming (Sapamine) structure is:

Its structure of A Keweier (Ahcovel) is:

Use wherein a kind of;

(3) alkyl ring-type nitrogen heterocyclic ring salt: a kind of as in the alkyl pyridine salt derivative (Pyridinium).

Give water used in the treatment fluid, available running water, too high as hardness in the water, then need use deionized water or distilled water instead.

With the transfer printing paper that above-mentioned DISPERSE DYES is made, can be commercially available transfer printing paper, can also can be the transfer printing paper of hand drawing pattern on newsprint, cartridge paper, art paper with transfer printing paper from seal.

The real silk fabric that uses is for being equipped with the pure silk goods of class.When transfer printing, be with the above-mentioned real silk fabric of handling and having dried that gives, its front is pasted mutually with the transfer printing recto, use transfer printing machine, also can in 160～230 ℃, press to scald can transfer printing to finish in 10～100 seconds with heating facilities such as electric iron.

The present invention has following advantage compared to existing technology: the present domestic transfer printing production technology of having only chemical ﹠ blended fabrics such as terylene, the described silk transfer printing of Japan Patent has only been used the polyalcohols swelling agent, does not use cationic surfactant simultaneously and based on its softener.So the present invention has following advantage: 1, the silk printed articles that present technique is produced, bright in colour, no yellowing phenomenon, feel is only more soft with swelling agent than Japan Patent, the natural style that has kept silk broadcloth, soaping fastness is (by standard: the GB-414-78 method) can reach 4～5 grades, improve 1～2 grade than the Japan Patent method.The existing silk printing method of product cost is low, effective, pollution-free.2, give finishing agent and do not contain adhesive and fluorescent bleaches, all nontoxic, raw material is easy to get inexpensive, and consumption is little, and water is also few.3, process equipment is simple, and available each station-service at present is in the transfer printing device and the transfer printing paper of chemical fibre silk fabrics such as terylene, and it is also very simple that silk gives treatment facility.4, can make exquisite handicraft with self-control Freehandhand-drawing transfer printing paper, improved the surcharge of silk greatly.
