METHOD FOR TREATING TEXTILE MATERIALS, AND TEXTILE MATERIALS TREATED IN SUCH A WAY, AND TEXTILE TREATING COMPOSITIONS

摘要

There are provided novel antistatic carpet yarns and carpets as well as novel compositions of matter and methods for the chemical treatment of carpet yarns and carpets in order to impart to such textile materials substantially durable hydrophilic, soil-repellency and antistatic properties that will be retained despite rigorous exposure to washing, foam, vacuum and steam cleaning, and wear under high compression loads (or foot-traffic), without any adverse effect on dyestuffs or flammability. The method consists essentially in first treating the carpet yarn or carpet made of preferably synthetic fiber material (by such per se well known methods as padding, spraying or transfer-roll) with an aqueous emulsion which forms a normally solid coating consisting essentially of:PPA. AT LEAST ONE PHASE OF AN ALKYLPHENOL WHICH IS INSOLUBLE IN WATER AND WHICH IS DISSOLVED IN AN ALCOHOL, A KETONE, OR OTHER ORGANIC SOLVENT;PPB. AT LEAST ONE PHASE OF A COPOLYMER OF DIMETHYL TEREPHTHALATE WITH A TETROL COMPOUND HAVING THE GENERAL FORMULA: ##EQU1## where a, b, c, d, e, f, g, and h are each integers and the total of a, b, c, and d is between 8 and 850 and the total of e, f, g, and h is between 8 and 1,000; which is relatively insoluble in water and which is dissolved in an alcohol, a ketone, or other organic solvent;PPC. AT LEAST ONE PHASE OF A REACTION PRODUCT OF AN ORGANIC DIISOCYANATE AND POLYETHYLENE GLYCOL OR OTHER POLYALKYLENE GLYCOL WHICH IS RELATIVELY INSOLUBLE IN WATER AND WHICH IS DISSOLVED IN AN ALCOHOL, A KETONE OR OTHER ORGANIC SOLVENT; PPD. AT LEAST ONE PHASE OF A FLUOROCHEMICAL COMPOUND DISPERSED IN WATER WHICH IS INSOLUBLE IN WATER AND WHICH CONTAINS A FLUORINATED ALIPHATIC RADICAL WITH AT LEAST THREE CARBON ATOMS, SAID COMPOUND HAVING AT LEAST A MAIN TRANSITION TEMPERATURE IN EXCESS OF APPROXIMATELY 45° C;PPe. at least one phase of an acrylic copolymer dispersed in water which is insoluble in water and which is derived from polymerizable monomers, whereby the acrylic copolymer compound has at least a main transition temperature in excess of approximately 45° C; andPPF. AT LEAST ONE PHASE OF A COMPOUND DISPERSED IN WATER WHICH CONTAINS A CROSS-LINKABLE, WATER- DISPERSIBLE POLYESTER AND AN AMINO RESIN WHICH CROSS-LINK UNDER THE INFLUENCE OF APPLIED HEAT TO FORM A WATER-INSOLUBLE FILM, SAID FILM HAVING AT LEAST A MAIN TRANSITION TEMPERATURE IN EXCESS OF APPROXIMATELY 45° C,PPwhereby at least one of the said phases is continuous; followed by heat treatment under dry heat for 10 seconds to 10 minutes at 100° to 200° C. The heat treatment step completes the chemical reaction between the above-mentioned phases, while at the same time effecting substantially complete removal of the alcohol, ketone or other organic solvent from the treated textile material.
