Definitions

• the object of the present invention is to materially simplify and improve a method of this kind: It has been found that as starting materials not only shrunk cotton fabrics enter into question but that likewise also non-shrunk cotton fabrics as well as other fibrous textiles are suitable for obtaining the desired result, such as wool, silk, artificial silk or the likefor textiles such as are known under the trade names of Vistra which is a mixture of staple fiber with cotton and Wollstra which is a mixture of staple fiber with wool. Furthermore. the reducing of the pores by shrinkage by means of an acid treatment can'be replaced by providing correspondingly small pores between the individual threads during the weaving.
• the fabric is impregnated with artificial resins, which are dissolved in volatile solvents, following the impregnation with water-repellent materials. These artificial resins are insoluble in water and consequently protect. the water-repellent impregnation against being removed by washing.
• the air transmissive propertiesof the fabric can be varied to a certain extent. 7
• the impregnation is, advantageously, carried out in a trough through which the fabric web is passed via guide'rolls in a manner as usual in the textile industry. It may also be suitable to employ means for tensioning the fabric as this is likewisecustomary in the textile industry.
• the fabric may, after the impregnation with artificial resins, be once more impregnated with water-repellent material, particularly with paramnsolutions or emulsions. In this way a thin covering layer of parafiin for the artificial resin is produced which layer renders the fabric fast to dipping in every respect.
• the fabric thus impregnated is then subjected to a calendering process.
• a calendering process it has been experienced that it is advantageous to apply low temperatures since at higher temperatures the artificial resins become somewhat viscous. Therefore, the fabrics are calendered at a temperature of approximately 0. and at a pressure lower than usual for this purpose.
• artificial resins the polymerisation products of vinyl acetate enter into question to the solutions of whichparaffin oils are added as softening agents.
• the fabric impregnated with these artificial resins is impregnated once more, after drying, with water-repellent material, for example, paraffin solutions or emulsions and is then calendered at about 25 C. and below the usual pressures applied for this purpose.
• water-repellent material for example, paraffin solutions or emulsions
• the method of producing lightweight, airtransmissive, waterproof fabric for garments having high resistivity to impairment of its waterproof property from the effects of washing comprising impregnating a textile fabric having small pores substantially of the size of the pores of a fabric of the type 70/70, 40/40 with liquid paraflin in a quantity insufficient, when dry, to close the pores of the fabric, drying the paraflin to solid state, then impregnating same fabric with from about 10 to 20 grams per square meter of vinyl acetate artificial resin, then calendering the fabric at a temperature of about 25 0., at which temperature the paraffin and resin jointly will not become viscous so as to prevent spreading of the, impregnants and closing the pores of the fabric from the effect of calendering.
