| abstract | 553,303. Sizing solutions. DU PONT DE NEMOURS & CO., E. I. Sept. 12, 1941, No. 11688. Convention date, Sept. 21, 1940. [Class 2 (iii)] An aqueous sizing solution particularly suitable for sizing knitting yarns composed of synthetic linear polyamides to be used in the manufacture of fully-fashioned hosiery and also suitable for sizing other linear polyamide structures and other yarns and fabrics such as cotton, silk, wool, linen, rayons and yarns prepared from vinyl and ethylene polymers comprises 3 to 12 per cent. by weight of a polyvinyl compound having hydroxyl groups, 5 to 25 per cent. on the weight of polyvinyl compound of boric acid and 5 to 30 per cent. on the weight of the polyvinyl compound of a polyethylene oxide as plasticizer. Suitable polyvinyl compounds bearing hydroxyl groups are the partial esters of polyvinyl alcohol, e.g. the acetates, propionates, glycollic acid esters, formates and lactates ; the partial ethers of polyvinyl alcohol, e.g. the glycol ethers, glycollic acid ethers and methyl and ethyl ethers ; the partial acetals of polyvinyl alcohol, e.g. the formal, acetal, glyoxal, propional and butyral ; and partial ketals, e.g. ethylmethyl ketal. Suitable polyethylene oxides have a molecular weight between 282 and 10,000, preferably between 1,000 and 2,000. Additional substances which may also be included in the aqueous sizing solutions are drying oils, e.g. oxidized linseed oil, chinawood and castor oils, modifying agents, e.g. polymeth acrylic acid, polymethacrylates, octyl alcohol, gums, waxes and resins, e.g. resorcinol-formaldehyde resin ; fillers, e.g. bentonite, starches, dextrine ; additional plasticizers, e.g. glycerol, glycols, sorbitol, glucose, diethylene and triethylene glycols, ethanol formamide, glycerol glycollate, ethanol acetamide, and tetraethylene and dimethoxytetraethylene glycols ; lubricants, e.g. mineral and olive, teaseed and other vegetable oils, sulphonated mineral and vegetable oils ; soaps, e.g. diglycol oleate and glycerol monoricinoleate ; preservatives, e.g. phenyl phenol; and corrosion inhibitors, e.g. triethanolamine and its fatty acid esters, diglycol oleate, morpholine and pyridine. The invention also includes a process of sizing synthetic linear polyamide yarns or other structures comprising treating the same with the aqueous solution. The drying oil may be applied in solution (i.e. methyl, isopropyl or butyl alcohols, or monoethyl or monomethyl ethers of ethylene glycol The size may also be gelled by an alkaline after-treatment of the sized yarn with vapours or solutions of alkaline substances. In an example a size solution comprises 8 per cent. partially saponified polyvinyl acetate, 1.6 per cent. boric acid and 1.2 per cent. polyethylene oxide. It is applied to yarns of polyhexamethylene adipamide, polydecamethylene sebacamide and polyhexamethylene sebacamide. The first yarn is afterwards treated with olive oil. Specifications 413,624 and 554,268 are referred to. |
