Rayon lining and method of its Manufacturing

United gloss fabric »factories AO. Wuppertal-Elberfeld

The invention relates to a method for producing Shrink-free lining made of rayon fabric »one of the best Naßknitterwinkel owns.

The increasing spread of so-called "wash-and-wear" clothing made of synthetic material in combination with wool and cotton "which does not shrink in the wash and does not need to be ironed" makes it necessary to also use ready-made ingredients such as lining and interlining , Sewing thread etc., which do not shrink in the laundry, in sufficient quantities and in ^rt wash ~ and-wear "quality available ·

Of the cellulose-based fabrics that can be considered for this purpose, one already has cotton and cellulose fabrics with mixtures different resin types shrink-proof and crease-resistant. With these high refinements, however, it comes next the desired finishing effects also lead to a considerable Deterioration in the technological properties of tissues. Their resistance to abrasion and buckling is particularly strong degraded. The tissue becomes brittle and rotten and therefore unusable.

It has now been found that it is possible to equip rayon fabrics in novel, advantageous catfish without significantly impairing their technological ^ v * ■;? ■ ?, data. π = that it is within the allowable tolerance of about $ ^X>; Do not shrink when washed at 4o ^e C in a washing machine, come out of the laundry satisfactorily smooth and therefore do not need to be ironed. According to the invention, this is done with the help of an appropriate combination of preparation and textile auxiliaries known per se in very specific proportions

The rayon fabrics are in an aqueous medium and in the presence of a wash-resistant, grip and leveling substance, a wetting agent, a vase-resistant, hydrophobic plasticizer and diammonophosphate as a catalyst, possibly with the simultaneous use of an organic complexing agent, with a mixture of 85-95 g / l Ethylenetriazine urea resin * 25-5 g / l melamine resin and a very small amount of carbamide resin treated. The thereby achieved surprisingly good and in practice unprecedented Atisrüstungseffekt makes the rayon fabric as feed material for the production of ⁿ wash-and-wear ⁿ -Clothes eminently suitable. r

Characteristic of the method according to the invention is the particularly low content of carb-f in the equipment liquor. ' ■ amid-fiarz from 10 to 12 g / l compared to known formulations; 60-80 g per liter to increase dimensional stability and shrinkage resistance, for crease resistance and washability Finishes 100 * 150 g per liter with the addition of one of the common ones Catalysts are applied will be the same equipment effects, especially an unfortunate one Dry wrinkle angle, also reached with a fraction the usual amounts of Garbaraid resin «In addition,.

what is of decisive importance for the use value; the tissue is, the tissue-damaging effect of the aggressive carbamide resin by the substantial reduction of its Avoided amounts.

For the creation of a sufficient wet crease angle and a shrink-free product, it is also necessary that very specific concentrations of ethylenetriazine-urea- and melamine resin in the equipment fleet are complied with The use of only 80 g / l Kthylenetriazln urea resin already results in insufficient shrinkage resistance and a bad wet crease angle

In detail, the beneficial effect of the finishing process according to the invention is based on the fact that the agents used together complement each other sensibly and through wrong dosage caused adverse effects vei »- mleden:

Ethylenetriazine urea resin, when used alone, has good shrinkage resistance, i.e. it prevents the goods from shrinking in the laundry, and results in a good wet wrinkle angle, but is the dry wrinkle angle bad.

The carbamide resin required to improve the dry wrinkle angle, on the other hand, has a negative impact on the textile technology Data of the fabric and especially sets the number of bending cycles greatly when used in the usual large amounts. By the according to the invention took place considerable By reducing its amount, these disadvantages are avoided and still, in conjunction with the existing one

Kthylenetrlazine urea resin, which achieves the desired favorable behavior of the fabric in the dry state.

The melamine component of the mixture further improves the wet crease angle of the fabric and its feel and the washing resistance of the finishing effect is favorably influenced. With an unusual and novel addition an organic complexing agent for the finishing liquor contributes to the improvement of the textile-technical data of the fabric and the presence of a wash-resistant «handle- and standing substance to improve the character of the goods and especially the abrasion resistance. The plasticizer, e.g. on Polyäthylenimln-Easis, through which the goods also have a high one receives a pleasing, appealing handle.

Diammonophosphate has proven particularly useful as a catalyst. In contrast to the usually as the catalyst magnesium chloride "Zlnkchlorid and zinc nitrate related" will bring about a greater reduction in strength of the product "is diammonium phosphate" distinguished by an especially mild action so that it does not lead to tissue damage due to a too violent extending condensation reaction "of Ausrüstungemittel" ^l

When performing the equipment according to the invention are to comply with certain conditions with regard to the pretreatment of the goods and the transport of the goods via the machine. One The reaction temperature is also of particular importance, which must be chosen so that a certain residual moisture remains in the fabric during pre-drying.

Proceed as follows in individual cases!

The goods are first washed in the usual way * noble, advantageous anion-active detergents are used, dyed on the sole and dried at 9o-12o * C. The goods are padded on a padder with a squeeze effect of about 15% and then dried at 70 ° C. so that about 10 pounds of residual moisture remain in them. Finally, the goods are condensed on a condensing oven for 8 minutes at | 4o * C while the goods are loosely guided. The goods can then shrink. A particularly beautiful and handy product is also obtained if the fabric is changed after pre-drying * after the finishing agent has been padded on and the condensation is carried out on it.
