Definitions

• This invention relates to the finishing of textile materials which have been treated for 1m- Darting water-repellent properties by impregnation with an organic nitrogen compound containing a group of at least ten carbon atoms, usually followed by heating to decompose the quaternary ammonium salt.
• My application Serial Number 220,329 contains a general description of the usual types of organic nitrogen compound suitable for the purpose.
• the object ofthe present invention is to improve the strength'or durability, or generally to increase the resistance to wear of materials which have been so treated to increase their water-repellency.
• the swelling may be produced by mixtures of compatible swelling agents or these agents in alternation with or without intermediate washing or by the application of incompatible swelling agents in alternation, or by the application of a combination of agents which singly do not produce swelling but which jointly, simultaneously, or in alternation, produce the desired effect.
• the swelling agents employed vary with the type of material being treated-
• the known swelling agents may besodium or potassium hydroxide, cuprammonium hydroxide, quaternary ammonium bases, sulphonium bases, caustic alkalis with carbon, bisulphide, caustic alkalis with ethylene oxide.
• acetone and water may be employed for examples With wool and silk suitable concentrations of alkaline hydroxides or ammonia'may be employed.
• the present invention enables. the properties 2 Claims. (01. s 11 6) of the waterproofed material to beimproved with the surprising and unexpected preservation of the water-repellent property.
• Example 1 A linen fabric is impregnated with a solution containing 3 grams octadecyloxymethylpyridinium chloride or N-carbomethoxyheptadecylaminomethyl pyridinium chloride orthe product sold under the registered trade-mark Velan PF. (a 15 quaternary ammonium salt derived from formaldehyde and a fatty alcohol) and 0.9 gram crystalline sodiumacetate in 100 ccs. water.
• Velan PF a 15 quaternary ammonium salt derived from formaldehyde and a fatty alcohol
• the swelling treatment may also be applied to textile materials which have been made waterrepellent and impregnated with resin or treated ,30 with a reactive aldehyde, as described in my copending application Serial No. 220,329.
• a linen fabric is impregnated with a solution containing 3 grams ofoctadecyloxymethylpyridinium chloride and 0.9 gram crystalline sodium acetate in 100 cos. of water.
• the invention not only includes cases in which the swelling follows the water-repellent treatment without interposition of other treatments (except the heating step which is part of the water-repellent treatment), but also cases in which a materialis made water-repellent as wellas subjected to other treatments.
• the invention includes the swelling of a material which has been treated by any of the processes described in my co-pending application Serial No. 220,329.
• the process of finishing linen materials which includes the steps of treating the material with a quaternary ammonium salt containing a group of at least ten carbon atoms and capable of producing water-repellency, heating the impregnated material'to produce a water-repellent eiTect and then swelling the water-repellent material with an alkaline swelling agent to improve its wear-resistance.
• the process of finishing linen materials which includes the steps of treating the material with a quaternary ammonium salt containing a group of at least ten carbon atoms and capable of producing water-repellency, heating the impregnated material to produce a waterrepell'ent efiect and swelling and shrinking the water-repellent material with an alkaline-swelling agent to improve its wear-resistance.
