摘要:
This invention provides a method for the treatment of cellulose containing fabrics with inorganic phosphorylating agents to obtain durable press or smooth drying fabrics. The method involves treating the cellulose-containing material with 8-16% of an inorganic phosphate, 16-32% of urea, 0.5-2.0% of a catronically emulsified polyethylene fabric softener, 0-6% of a polyacrylate or suitable polymer emulsion (glass transition temperature: -20.degree. to -43.degree. C.), and then drying the fabric at 60.degree.-100.degree. C. for 3-7 minutes. The fabric is crosslinked to obtain durable press or smooth drying properties by curing at 160.degree.-170.degree. C. for 3-9 minutes.
摘要:
A substantially surfactant-free composition consists essentially of a water-soluble phosphate and a water-insoluble alumina having a particle size less than 3 microns. An aqueous mixture of the phosphate and alumina is useful for cleaning carpets and imparting a soil repellent finish thereto.
摘要:
Highly absorbent cellulose fibers with ion exchange properties are obtained by phosphorylating cellulose fibers, hydrolyzing the fiber walls with acid, converting the phosphorylated fibers to the sodium salt form, mechanically refining these fibers to rupture the primary fiber wall and permit subsequent swelling or ballooning, acidifying the refined fibers to reconvert the phosphorylated cellulose into the acid form, and drying the fibers in a manner to substantially avoid appreciable hydrogen bonding. The acid pH of these highly absorbent fibers makes them ideally suited as an absorbent component in catamenial tampons employed to establish and maintain a desirable acidic condition in the vagina.
摘要:
A dyed union knit fabric comprised of at least a polyurethane elastic fiber containing a chlorine-induced degradation inhibitor in a proportion of 0.5-4.5 weight % relative to the weight of the fiber, and a polyamide fiber and/or a cation dyeable polyester fiber, which has been dyed with mixed dyes of acid dyes, dispersion dyes, metal-complex dyes, reactive dyes and direct dyes, and markedly improved in resistance to chlorine-induced change in shade by allowing to contain at least one compound having a reaction amount of chlorine of 50 milliequivalent per gram or more, specifically one member of mono- and/or polyhydroxybenzene derivatives in a proportion of 0.1-20% relative to the weight of the fiber; and a method for manufacturing same. According to the present invention, excellent resistance to chlorine-induced change in shade as well as chlorine-induced degradation can be afforded to the dyed union knit fabric.
摘要:
Natural and synthetic textile materials and blends thereof are disclosed containing at least one water-soluble, neutral alkanolamine, ammonium or mixed alkanolamine and ammonium salt of a phosphoric acid wherein said acid is selected from the group consisting of orthophosphoric acid and polyphosphoric acid. Polyester-cotton fabrics are rendered antistatic by treatment with these ionic bonded salts in the proportion of about 0.5 to about 10 percent by weight based on the weight of the textile fabric.
摘要:
AN IMPROVED HIGHLY ABSORBENT FIBER IS OBTAINED BY PHOSPHORYLATING CELLULOSE PULP FIBERS. A PREFERRED FORM OF THE PRODUCT IS OBTAINED BY CHEMICALLY SUBSTITUTING PHOSPHATE GROUPS FOR HYDROXYLS ON THE CELLULOSE, HYDROLYTICALLY DEGRADING THE FIBER WALLS AND THEN CONVERTING THE PARTIALLY SUBSTITUTED AND HYDROLYZED CELLULOSE FIBERS TO THE SALT FORM BY ION EXCHANGE. SUBSEQUENT MECHANICAL REFINING AND SOLVENT DRYING OF THE FIBERS RESULTS IN A PRODUCT HAVING CAPILLARY SUCTION FORCES SIGNIFICANTLY HIGHER THAN CONVENTIONAL ABSORBENT FIBER MATERIALS.
