-in 1

The invention relates to textile finishing, in particular to silk printing methods. fabrics, from diacetate fibers.

Cellulose diacetate and fibrous materials on its base have less disperse dyes than with triacetate and polyester fibers. In this connection, the intensity and strength of the colors for wet treatments of diacetate fabrics is low. In addition, diazetsedtnyh fabrics have a high electrified.

A known method of printing diacetate tissues with disperse dyes, followed by steaming. This method requires the use of a urea printing intensifier in printing ink. L.

The disadvantages of this method are the low intensity and durability of printed DAQ fabrics.

The purpose of the invention is to increase the intensity and strength of colorings and impart antistatic properties to diacetate fabrics.

The goal is achieved by printing diacetate fabrics followed by steaming the fabric before printing is treated with a "composition containing, in wt.%: A polycondensation product of ethyl chloride with polyethylene glycol and diethylenetriamine (zpamin O) 8-10, urea 1-2, soda ash O, 5-0, 1-2 .and water - the rest.

Examples (Prepared for

10 printing diacetate (DAC) fabric Les, rt. 32485, treated on a padding with a solution containing epamin A, urea, soda, borax (Table 1), squeezed to 90-100% of weight gain and dried 5 at 80-95 C. The thus prepared DAC fabric is printed with the following printing paste, weight .%: Disperse dye blue K1

Then they are steamed at 102-103 C for 20 min and washed with cold running water and warm (t - 45-50s) with Novost paste solution (1 g / l).

In parallel, under the same conditions, a DAC fabric is printed in a known manner without prior padding (Example 10). In this case,

printing paste additionally injected urea 20 g / kg.

As can be seen from the data given in table. 2 use in the borax composition with a concentration of 1-2 wt.% Allows you to maintain a higher whiteness of the fabric before printing compared to the control sample and thus the purity of the color of the printed fabric. Consider optimum -10 wt.% Epamin and 2-3 wt.% Urea in solution. Similar patterns were obtained when printing with yellow and red disperse dyes. ,

The fabrics dyed according to the proposed method under optimal DAC conditions have increased color resistance to multiple washes (approximately 2 times), dry and wet friction, and a wet and dye solution (Table 3). The specific surface resistance of the fabric is separated in the conditions of Example 9 for three pores. dka higher (3 ,.) compared with the control.

Thus, this invention allows to increase the intensity
