Definitions
- the present invention relates to a continuous process for the mercerization of sheet-like cotton and cotton blended articles, polyalkylene glycols and / or polyethylene glycol mono (C 1 to C 4) alkyl ethers being added to the mercerizing liquor - and the sheet-like textile material padded therewith immediately dried and then in a conventional manner is completed.
- Mercerization ie the treatment of cotton and cotton blends with strong sodium hydroxide solution under tension, has long been known. This treatment achieves a considerable increase in gloss, while at the same time improving the tear resistance. The increased dye absorption and the improved product appearance are also essential (see H. Rath, "Textbook of Textile Chemistry", 3rd edition, 1972, Springer Verlag Berlin-Heidelberg-New York, pages 67-73).
- the disadvantages of the known method are that own machines are required for this. Except the effects, especially with knitwear, still leave something to be desired.
- the object of the invention is therefore to develop a continuous mercerization process in which optimal mercerization effects are achieved and, above all, there is no significant shrinkage of the treated material.
- This object is achieved in that certain compounds are added to the mercerizing liquor.
- the present invention accordingly relates to a continuous process for the mercerization of sheet-like cotton and cotton blend articles by padding with strong sodium hydroxide solution in the presence of wetting agents, which is characterized in that the mercerizing solution contains polyalkylene glycols and / or polyethylene glycol mono (C 1 to C 4) alkyl ethers be added and the tissue then immediately dried at high temperature under tension and then finished in a known manner.
- the mercerizing solution contains polyalkylene glycols and / or polyethylene glycol mono (C 1 to C 4) alkyl ethers be added and the tissue then immediately dried at high temperature under tension and then finished in a known manner.
- the sodium hydroxide solution used has a concentration of 10 to 26% by weight, preferably 13 to 19% by weight, very particularly preferably 15 to 17% by weight, and is therefore preferably less than the sodium hydroxide solution normally used.
- alkali-resistant wetting agents examples include sulfates of C 4 to C 12 alcohols, sulfated polyether alcohols and sulfated ethanolamines, but also alkyl sulfonates, alkylarylsulfonates and nonionic compounds, e.g. ethoxylated fatty alcohols and phenols, and mixtures of the listed compounds. These compounds are described in detail in the literature.
- the polyalkylene glycols and / or polyethylene glycol mono (C 1 to C 4) alkyl ethers used according to the invention have a molecular weight of 100 to 2,000, in particular 200 to 600. 10 g / 1 to 60 g / l, in particular 20 g / 1 to 40 g / 1, of the mercerizing liquor are used. Because of the better solubility, the polyethylene glycols may be mentioned as polyalkylene glycols, but polypropylene glycols can also be used.
- the polyethylene glycol mono (C 1 to C 4) alkyl ethers are also preferably used in the process according to the invention because of their good solubility in water.
- the fabric is washed in a known manner, the last residues of lye are neutralized with acid, in particular hydrochloric acid, and dried again.
- acid in particular hydrochloric acid
- the final drying can also be dispensed with and further processed wet-on-wet in a known manner.
- All sheet-like materials accessible to the known mercerization can be mercerized by the method according to the invention. Pure cotton fabrics and knits are primarily mercerized. Mixtures of cotton with man-made fibers can also be mercerized, although the mercerization only makes sense if the cotton content is at least 50% by weight.
- the treated material is characterized by a complete equalization of the intramicellar swelling, has not shrunk and the dye absorption capacity has been significantly improved.
- Cotton raw material (160 cm wide; bleached and boiled; 220 g / m 2 ) is padded with a 20% sodium hydroxide solution containing 40 g / 1 polyethylene glycol 1000 and 20 g / 1 of the wetting agent mentioned in Example 1 (liquor absorption 105%) and ge immediately at 100 to 110 0 C on the stenter to a residual moisture of approx. 8% dries. The completion takes place as indicated in Example 1.
- the fabric which has a final width of 160 cm, shows an excellent product appearance.
- the same fabric is padded in the absence of polyethylene glycol, left to rest and only then dried and finished, the main drawback is that the fabric shrinks to 130 cm and the intramicellar swelling (product image) is not as uniform is pronounced.
- a cotton / polyester blend 50/50 (raw material with usual pretreatment; 145 g / m 2 ) is washed with a 17% sodium hydroxide solution, the 25 g / l polyethylene glycol-600-mono-n-propyl ether and 15 g / l of a commercially available wetting agent ( Contains 2-ethylhexanol sulfate; washing-active substance 75%), padded (liquor pick-up 65%) and immediately afterwards dried at 90 to 100 ° C on the stenter to a residual moisture of 4% and finished as already described in Example 1.
- a commercially available wetting agent Contains 2-ethylhexanol sulfate; washing-active substance 75
- the tissue treated in this way is in the desired width, the intramicellar swelling is uniform and the other mercerizing effects correspond at least to the known effects.
- 50 g / 1 of the same polyethylene glycol ether can be used.
- Example 3 is repeated, but drying is carried out after the padding.
- Example 1 is repeated using 24% sodium hydroxide solution.
- Example 1 is repeated using 14% sodium hydroxide solution and polypropylene glycol 600.
- Cotton knitwear (pretreatment see example 1; 165 g / m 2 ; width of the raw material 180 cm) is padded with 15% sodium hydroxide solution, which contains 35 g / 1 polyethylene glycol 200 and 10 g / 1 of a commercially available, alkali-resistant wetting agent (liquor absorption 85% ) and immediately dried at 105 ° C on the stenter to a residual moisture of 8% and as in example 1 described, completed.
- sodium hydroxide solution which contains 35 g / 1 polyethylene glycol 200 and 10 g / 1 of a commercially available, alkali-resistant wetting agent (liquor absorption 85% ) and immediately dried at 105 ° C on the stenter to a residual moisture of 8% and as in example 1 described, completed.
- the cotton knitwear which is almost unchanged in width, is outstandingly mercerized with a particularly high dye absorption capacity.
- Example 1 is repeated using polyethylene glycol 400 monomethyl ether. Good effects are obtained immediately.
