• polyethylene glycol dihalide e.g'. chloride, bromide or iodide
• analogue is condensed v(with release of hydrogen halide) with an amine, the nitrogen of which contains at least two active hydrogen.
• Typical of such amines are methylamine, ethylamine, propylamine, butylamine, amylamine, hexylamine, dodecylamine, 'allylamine, monoethanolamine, 3-isopropyl-n-propylamine, S-methoxy-npropylamine, d-iethylenetriamine, ,bis(3 aminopropyl)- other common yarn-treating agents which are not stable in that pH range, making it necessary to apply the agent in a treatment step distinct from that employed for other purposes.

• the shaped structure is treated with an emulsion of a mixture of a polyepoxide and a compound of Formula I.
• the emulsion is prepared by dispersing the polyamine and the polyepoxide in water at room temperature with vigorous stirring.
• the concentration of reactants in the emulsion- may vary widely. A concentration as high as 20% maybe used. However, more dilute emulsions containing from about 1 to about 5% of reactants are generally preferred. Any such finishing suspension having a concentration suitable to provide from about a 0.3% to about a 5% solids iokup based on the dry material is satisfactory.
• the reaction product can be applied to the structure by conventional methods such as dipping, padding, brushing, spraying, and the like. After removal of excess liquid, by wringing in the case of a textile, it is usually convenient to dry and cure the structure in one operation.

• the ratio of polyarnine:polyepoxide is maintained within the limits of 10:3 to 10:7. Higher ratios of polyepoxide such as 1:1 may be used however, as illustrated in the examples. Larger amounts of the polyepoxide may be employed but generally result in a harsher hand.
• the reactants may be ap-- plied to the shaped structure without the presence of catalysts, it is preferred to include a minor amount of an epoxide curing catalyst.
• an epoxide curing catalyst Such materials not only hasten the curing operation or permit curing at lower temperature, but also increase adherence of the antistatic agent to the structure.
• Such materials are well known in the art, as described, for instance in United States Patent No. 2,752,269.
• the reactant mixture may be either acidic or alkaline, alkaline conditions usually cause yellowing.
• Optimum conditions of curing will depend upon the identity of the reactants, the identity of the textile and whether or not a catalyst is included. Room temperature is adequate for forming the cured antistatic finish when a catalyst is used. Generally, however, a temperature of at least about 240 F. is preferred to accomplish eflicient drying of the textile. Usually temperature adjustment is made to permit curing and drying in a 3- minute interval. A temperature of about 212 F. to 250 F. is recommended for most textile materials. For operation in the absence of a catalyst a curing cycle of about 10 minutes at 270 F. is adequate.
