Brennan and Edward J. Sites ABSTRACT: The present invention is concerned with the use of high molecular polyethylene glycol as a means for increasing the absorptivity of cellulosic fabrics. It is preferably used in applying to the fabric an aqueous preparation that contains a dyestuff, a flameproofing agent, a hydrophobizing agent or an antimycotic PROCESS FOR IMPROVING FABRICS CONTAINING CELLULOSIC FIBERS The present invention is concerned with the use of highmolecular polyethyleneglycol as a means for increasing the absorptivity of cellulosic fabrics for aqueous preparations used for improving them.
The aqueous preparations used for improving purposes are in the first place baths used for impregnating cellulosic fabrics, whose absorptivity for the bath is increased by the addition of high-molecular polyethyleneglycol. Preparations for coating or printing cellulosic fabrics, especially printing inks for screen printing are in addition suitable. By the addition of high-molecular polyethyleneglycol in an amount of, for exampie, 0.] to 2 g. per kg. of printing ink the absorptivity of the fabric to be printed is increased.
As a rule a polyethyleneglycol is used that has an average molecular weight from 10 to preferably from 10 to 10''. Polyethyleneglycols of such high molecular weights are prepared from alkylene oxides, preferably from ethylene oxide, and are water-soluble. They are obtained in the form of white, dry, fine powders which are easy to pour.
When a small amount, preferably 0.1 to 2 g. per liter, of these polyethyleneglycols is added to an impregnating liquor, the absorptivity of the fabric is substantially increased. Particularly suitable is an addition of 0.25 to l g. of polyethyleneglycol per liter of impregnating liquor.
By cellulosic fabrics are meant fabrics of native or regenerated cellulose, or mixed weaves of cellulose and other fibers, for example polyester, polyamide, polyacrylonitrile or wool fibers.
These polyethyleneglycols are especially suitable for increasing the absorptivity of the fabrics for the liquor when it is desired to impregnate fabrics having poor absorptivity, for example tarpaulins.
Whereas on readily absorbent fabrics the conventional wetting agents produce no increase and on poorly absorbent fabrics only little increase in the absorptivity for the liquor, a distinct or even a substantial improvement in the absorptivity is achieved with the use of the high-molecular polyethyleneglycols.
The cellulosic fabrics may beimpregnated in the usual manner, for example by the immersion or exhaustion method; it is of special advantage to pad the fabrics.
inter alia, the high-molecular polyethyleneglycols are used in impregnating liquors to provide cellulosic fabrics with, for example, an antimicrobial, crease-resistant, shrink-resistant, oil-repellent soft-handle and especially a mouldproof, flameproof or hydrophobic finish. These polyethyleneglycols may also be incorporated with dyebaths.
The highmolecular polyethyleneglycols have the further advantage that they are readily compatible with other adjuvants and improving agents so that, for example, when used in a hydrophobizing process they do not impair the final hydrophobic effects achieved. Furthermore, in their practical application the high-molecular polyethyleneglycols practically produce no foaming.
The impregnating liquors may, of course, contain in addition to polyethyleneglycol and the improving agent various other adjuvants, for example further wetting agents, thickeners, emulsifiers, solubilizers or migration inhibitors.
The impregnating liquors are advantageously prepared by slowly sprinkling the polyethyleneglycol into cold water and cautiously stirring until all has dissolved. Vigorous stirring could destroy the long polymer chains, so that the activity of the impregnating adjuvants in increasing the liquor absorption could be substantially annulled.
Accordingly, the present invention includes also a process for improving, especially by impregnating, cellulosic fabrics, characterized in that the aqueous preparation for improving the fabric contains as a means for increasing the absorptivity, high-molecular polyethyleneglycol.
Percentages and parts in the following examples are by weight.
EXAMPLE 1 To measure the liquor absorption fabrics of good and poor absorptivity are padded in baths containing different wetting agents. All baths contain per liter:
400 g. of an percent aqueous solution of 3- (dimethylphosphono)-methylolpropionamide 80 g. of a 60 percent aqueous solution of a methylolmelamine methyl ether lO g. of urea 20 ml. of a 20 percent aqueous polyethylene emulsion and 4 g. of ammonium chloride.
The following wetting agents are further added to such a bath:
bath 1: no wetting agent bath 2: l0 g./iiter ofa 12.5 percent solution ofa condensation product of 1 mol of p-tertiary octylphenol with 8 mols of ethylene oxide bath 3: 50 g./liter of a wetting emulsion consisting of 22 g. of a reaction product of 80 parts of a hexamethylolmelamine butyl ether with parts of a polyethyleneglycol, mol wt. 4000 408 g. of water and 570 g. of cyclohexanol.
bath 4: 0.25 g./liter of a polyethyleneglycol, mol wt. 10 to 10 bath 5: 0.5 g./liter of a polyethyleneglycol, mol wt. 10 to Padding in the baths 1 to 5 produces the following liquor absorption values:

Fabric k of phosphorus on fabric padded in bath l cellulose serge merccrized and bleached cellulosic turpaulin fabric ln keeping with the increase in liquor absorbed the flameproof finishes with addition of polyethyleneglycol also display a higher phosphorus content.

The baths are composed as follows:

The waterrepellency is tested by way of the water absorption after a short spray. This so-called spray test is performed according to SVMT 25/D 1332 (1950) or ASTM D 583-40T 1944) or AATCC Standard Test Method 22-52:

The preparation contains, referred to the starting substances, 4 percent of phenyl-mercuric acetate and 10 percent ofdimethylolmelamine.
The padded fabric is dried, using in both finishing operations the identical roller pressure.
The two finishes are then tested for their efficacy in preventing the growth of micro-organisms by placing round blanks of 25 mm. diameter of the two finished tarpaulin fabrics on beerwort-agar plates and inoculating the plates with Aspergillus niger. The plates are then incubated for 72 hours at 30 C.
The evaluation extends, on one hand, to the inhibitory zone found around the blanks and, on the other hand, to the growth detected microscopically underneath and/or on the fabric:

The addition of polyethyleneglycol to the bath for finish B very substantially increases the amount ofliquor retained after squeezing and ensures-for an equal content of active substance on the fabric-a better resistance of the mould-resistant finish to washing.
EXAMPLE 5 To test the increased liquor absorption of cellulosic fabrics in dyebaths containing high-molecular polyethyleneglycol specimens of cotton tricot are padded in liquors containing per liter, 5 g. of a water-soluble red reactive dyestuff and 0-100 g. of a 1 percent solution of a polyethyleneglycol of molecular weight 10 to 10 at 25 C. under a roller pressure of kg./cm I By measuring the amount ofliquor absorbed (after squeezing) the following values at the indicated wetting agent concentrations are obtained:
Thus, the baths 2 to 6 lead to a much greater liquor absorption than does bath 1.
We claim:
1. A process for improving the absorptivity of cellulosic fabric which comprises applying to said fabric an aqueous composition containing 0.] to 2 g. per liter of a polyethyleneglycol of average molecular weight between 10" and 10" as an agent for increasing the absorptivity ofthe cellulose fabric and a textile improving agent.
