The present invention relates to a process for the treatment of polyester and polyurethane-containing blended fabrics, comprising the following step:

• (A) contacting with 0.1 to 50 wt .-%, based on blended fabric, of at least one colorless low molecular weight substance. The present invention also relates to a method further comprising the steps
• (b) dyeing with at least one disperse dye,
• (c) reductive post-purification and
• (d) optionally rinsing.

Farther The present invention relates to polyester and polyurethane-containing Blended fabric, available according to the method of the invention, as well as garments, made of polyester according to the invention and polyurethane-containing blended fabric.

at the coloring of polyester and polyurethane-containing blended fabrics occur in the Practice problems on. Pure polyester can be well with so-called Dye disperse dyes, in polyester usually dissolved molecularly dispersed available. Many commonly used in blended fabrics Fiber materials, for example polyamide, cotton, take disperse dyes under dyeing usual Do not give up conditions and give them in rinsing baths usual in textile dyeing, Completely again.

Different looks at polyester and polyurethane blended fabrics, i.e. Blended fabrics containing polyester and polyurethane fibers. Polyurethane fibers are capable of producing large quantities of disperse dyes to solve or to bind, and then give e.g. at the laundry and ironing respectively certain quantities again. Also, the color proves to sweat as very inconsistent. Furthermore, it is observed that at the large capacity the polyurethane fibers to disperse dyes the coloring of Polyester is often done only to unsatisfactory extent.

So far proposed solutions proved to be technically unsatisfactory. Trials, blended fabrics dyed Polyester fibers and undyed To produce polyurethane fibers, for example by so-called Spin dyeing, to lead to a big one restriction in the color palette.

It So the task was to provide a method which Polyester- and polyurethane-containing blended fabric supplies that are dye with a good fastness level. It persisted the task of providing a process to polyester and Coloring polyurethane-containing blended fabrics. It persisted the task, really colored polyester and polyurethane-containing To provide blended fabrics, and the job was to paint really colored clothing made of polyester- and polyurethane-containing blended fabric, which avoid the disadvantages of the prior art.

Accordingly, became Found the initially defined method.

• (a) Inkontaktbringen mit 0,1 bis 50 Gew.-%, bezogen auf Mischgewebe, mindestens eines farblosen niedermolekularen Stoffes.

The process according to the invention for the treatment of polyester and polyurethane-containing blended fabric comprises the following step:

The Contacting according to the invention mixed fabric with colorless low molecular weight substance according to step (a) is preferably carried out in aqueous Fleet.

In Step (a) can liquor ratio and pH of the liquor with those of the usual dyeing conditions with the dyeing Disperse dyes correspond.

In an embodiment In the present invention, the liquor ratio in step (a) is in the range from 40: 1 to 3: 1, especially 20: 1 to 3: 1.

In one embodiment of the present invention, the preferred pH in step (a) is in the range of 3 to 10. Ester group-free low molecular weight substances can be used over the entire pH range from 3 to 10. Ester group-containing low molecular weight substances are preferably used in a range from 3 to 9, particularly preferably from 3 to 7 and very particularly preferably from 4 to 6.

In an embodiment of the present invention the amount of colorless low molecular weight substance in the range from 0.1 to 10 wt .-%, preferably 0.1 to 5 wt .-% and especially preferably from 0.2 to 3 wt .-%.

In an embodiment In the present invention, the contacting of the invention takes place Mixed fabric with colorless low molecular weight substance according to step (a) at a temperature ranging from room temperature to 100 ° C, preferably from 40 to 100 ° C and more preferably from 70 to 90 ° C.

In an embodiment In the present invention, the contacting of the invention takes place Mixed fabric with colorless low molecular weight substance according to step (a) after the exhaustion process.

Do you wish According to the invention according to To work exhaust process, one works in aqueous liquor preferably at temperatures of 60 to 135, usually around 130 ° C. Do you wish at temperatures above 100 ° C to work, it is advantageous to work in a high-temperature dyeing apparatus, which is above 100 ° C under pressure.

At the Extraction process brings you to be treated blended fabric at a Temperature from 10 to 35 ° C in a watery Fleet containing colorless low molecular weight substance and optionally at least one aggregate, e.g. Dispersant, one or several surfactants, carboxylic acids or solicitors, and whose pH is usually 3 to 10, preferably 3 to 9, is. The liquor ratio (Weight ratio Mixed fabric: liquor) amounts to while 1: 3 to 1:40, preferably 1: 3 to 1:20. The watery fleet heated to the treatment temperature at a heating rate of 1 to 3 ° C / min up to 130 ° C and stops 15 to 60 minutes at this temperature.

When Dispersants are preferably used such dispersants, which are colorless and at temperatures up to at least 210 ° C against yellowing are stable. Preferably used dispersants dye the Fibers to be treated polyester and polyurethane-containing blended fabric not on.

Particularly suitable dispersants are, for example, anionic or nonionic dispersants, especially those from the class of ethylene diamine-ethylene oxide-propylene oxide adducts and the ethylene oxide-propylene oxide adducts with fatty alcohols, higher fatty acids or alkylphenols, such as in US 4,218,218 described or dispersants, as described in DE-A 27 45 449. Particularly suitable are in US 5,186,846 disclosed formaldehyde-condensed sulfonation products of aromatics and aromatic mixtures.

Suitable surfactants are ionic, nonionic and zwitterionic surfactants. Particularly suitable surfactants are selected from the class of polyethoxylated fatty acids, aliphatic or mono- or poly-olefinically unsaturated C ₁₂ -C ₂₀ -alcohols, C ₁₂ -C ₂₀ -amines or oxoalcohols.

Suitable solubilizers are based on short-chain esters, for example C ₁ -C ₄ -alkyl esters and C ₁ -C ₄ -dialkyl esters of terephthalic acid, aliphatic dicarboxylic acids or monocarboxylic acids such as, for example, acetic acid. Mixtures of the abovementioned solubilizers are also suitable.

in the Following contact with low molecular weight colorless Fabric according to step (a) you can rinse and / or dry.

By the inventive method receives treated polyester and polyurethane-containing blended fabric, which can be dyed with a good level of fastness and also subject matter of the present invention.

Without the first to indicate that preference is given to a theory Measurements such that treated polyester and polyurethane-containing blended fabric low molecular weight colorless fabric dissolved in the fibers at least in certain proportions molecularly disperse or contains bound and mostly in polyurethane fibers.

In one embodiment of the present invention, the following steps may be followed at step (a):

• (b) dyeing with at least one disperse dye,
• (c) reductive post-purification and

Do you wish to join step (a) steps (b), (c) and optionally (d) so can you do without rinsing and drying steps between steps (a) and (b) operate and terminate Treatment according to step (a) a staining step (b) on.

In Step (b) colors with at least one disperse dye.

Prefers one dyes in step (b) with a mixture of two or more disperse dyes to dye. As disperse dyes for dyeing in step (b), in particular azo, anthraquinone, quinophthalone, Benzodifurane, methine and azamethine dyes that are free from acidic or ionic groups.
