Definitions
- the invention relates to a process for the production of dyed textile materials consisting of polyester and polyamide.
- Dyeing process for polyester and polyamide fibers are known from the literature (see Ullmann's Encyclopedia of Industrial Chemistry, 6 th Edition, 1998). Disperse dyes are preferred for the dyeing of polyester fibers and acid dyes for the dyeing of polyamide fibers.
- polyester / polyamide-microfiber mixtures are known from the literature (brochure from Sandoz Chemical AG).
- the invention has for its object to provide a method that allows the production of dyed, made of polyester and polyamide, textile materials that allows a fastness to washing for medium and deep shades up to at least 60 ° C.
- the object is achieved by a process in which the textile material is dyed with polyester-dyeing disperse dye or with pigments, excess dye is removed and the dyeing of the polyamide component is carried out with the aid of vat dyes, leuco vat dyes, sulfur dyes or soluble sulfur dyes, the dyes mentioned above being used if it is necessary in order to achieve solubility of the same, encapsulated and, after being drawn up, oxidatively converted into the real dyes.
- wash fastnesses of up to at least 60 ° C are achieved even for medium and deep shades.
- no special aftertreatment is necessary to achieve these color fastnesses, and savings in terms of chemicals and the water required to carry out the process are thereby achieved.
- the coloring of the polyamide portion is preferably carried out with the aid of
- vat dyes made. The vat dyes have proven to be the most stable in terms of their light, wet fastness (fastness to washing, water and sweat).
- a process is particularly preferred in which the polyester portion is first colored with disperse dyes, followed by reductive cleaning at about 80 ° C. and then the polyamide portion is colored. This advantageous variant of the method leads to a higher wet fastness of the colored materials.
- Another preferred variant of the process is that the dyeing is carried out in a dye bath, the excess polyester-dyeing disperse dye being removed simultaneously with the vatting with the aid of reducing agents such as sodium dithionite, glucose or sodium sulfide.
- the dyeing in only one dye bath improves the economics of dyeing, since fewer chemicals, water and only one installation are required.
- Nonwovens are preferably used as textile materials in the process. In this way, these inexpensive materials can be refined using dyeing technology.
- Micro, staple fiber or spunbonded nonwovens are advantageously used as textile materials.
- the dyeing difficulties known with these microfiber nonwovens were surprisingly overcome.
- Microfilament nonwovens consisting of spun-dyed polyester and / or polyamides are particularly preferred. With these microfilament nonwovens, both light and wet color fastness are further increased.
- a microfilament nonwoven fabric consisting of 35 wt .-% polyamide and 65 wt .-% polyester is, in a two-stage exhaust with disperse dyes such as Dispersol ®, and vat dyes, such as Indanthren ®, dyed.
- disperse dyes such as Dispersol ®
- vat dyes such as Indanthren ®
- the dispersol dyes specified in Table 1 are suspended in a first bath with 1 g / l of a dispersant, Setamol ® WS, 0.5 g of a complexing agent, such as Trilon ® TA powder.
- the pH of the dispersion is adjusted to pH 4.5 to 5 with acetic acid.
- the liquor ratio is 1:10.
- the dyeing takes place over 45 min at 130 ° C.
- vat dyes also given in Table 1.
- the dye is dispersed together with 2 ml / l of a protective colloid, such as Dekol ® SN, and 0.5 g / l of a complexing agent, such as Trilon ® TA, and with 2.0 ml / l of 38 ° Be and 2.0 sodium hydroxide solution g / l sodium dithionite fogged.
- the dyeing is carried out at 80 ° C for 30 min.
- the mixture is then cooled to 60 ° C. and oxidized at 60 ° C. for a further 10 minutes.
- 50% hydrogen peroxide solution or a nitrobenzenesulfonic acid is used. Saline. Excess dye is washed out with water.
- Example 2 A microfilament nonwoven fabric according to Example 1 is dyed with a mixture of the disperse and vat dyes given in Table 1 in a one-pot process. Both the disperse dye and the vat dye are dispersed together with 1 g / l dispersant (Setamol ® WS), 0.5 g / l of a complexing agent (Trilon ® TA powder) and 2 ml / l of a protective colloid (Dekol ® SN) adjusted to a pH of 4.5 to 5 with acetic acid. The liquor ratio is 1:10. The dyeing takes place at 130 ° C for 45 min. It is then cooled to 80.degree.
- 1 g / l dispersant Setamol ® WS
- Trilon ® TA powder 0.5 g / l of a complexing agent
- Dekol ® SN ml / l of a protective colloid
- the dyebath is then cooled to 60 ° C. and oxidized at 60 ° C. for a further 10 minutes.
- the dyed microfilament nonwoven fabric is rinsed with water to remove excess dye.
- a microfilament nonwoven fabric according to Example 1 is a two-stage exhaust dyeing with vat dyes, such as Indanthren ®, and a subsequent disperse dye staining with dyes such as Dispersol ® subjected.
- the combined disperse dyes and vat dyes are given in Table 1.
- the dye baths are composed as in Example 1, with the difference that the dyeing is carried out first with the vat dyes.
- a microfilament nonwoven according to Example 1 is dyed in a padding process using the thermosol pad-steam process with disperse and vat dyes.
- the composition of the padding liquor corresponds to the dyebath composition according to Example 2.
- the dye is padded at 100 ° C., dried for 2 minutes and fixed at 215 ° C. for 60 s.
- To develop the vat dye 2 ml / l sodium hydroxide solution 38 ° Be and 2 g / l of a reducing agent, namely sodium dithionite (concentrated hydrosulfite ® ), are padded. Finally, steaming is carried out at 102 ° C. for 60 s and rinsed with water after oxidation.
- a microfilament nonwoven fabric is printed with pigment (70 g / l
- the pigment and the leuco vat dye are in a binder system consisting of water, 9.0 g / l of a defoamer (Respumit ® 3300), 9.0 g / l of a running aid (Emulsifier ® VA02), 110.0 g / l of a binder (Acramin ® CLW), 30.0 g / l of a thickener (Acraconz ® BN) and 9.0 g / l of a melanin resin crosslinker (Cassurit ® HML) are mixed to form a printing paste.
- the printing paste is applied to the nonwoven using printing templates. Then dried at 130 ° C for 1 min and the pigment fixed at 160 ° C for 1 min.
