A method for reducing endotoxin in cotten fiber or dust is disclosed. Cotton fiber or dust is detoxified in a solution selected from the group consisting of 95% ethanol and hydrochloric acid; 95% ethanol and sodium hydroxide; and dimethylsulfoxide.

Method for reduction of endotoxin in cotton lint or dust

Cotton and cotton-blended fabrics are impregnated with an emulsion containing an N-methylolated urea resin, a Lewis-acid catalyst, an emulsifying agent, and softener in a water-chlorinated solvent formulation to impart improved durable press properties.

Emulsion systems for imparting durable press properties to cotton and

Stable oil and water emulsions, prepared such that a water-soluble phosphorus monomer, a melamine-formaldehyde resin, and an emulsifier of high HLB value are in the water phase while an oil soluble halogenated phosphate and emulsifier of low HLB value are in a chlorinated solvent, can be used to impart durable-to-laundering flame retardancy to both cotton and cotton-polyester textiles provided the HLB value of the final emulsion is greater than 9 and not over 15.1.
