    Abstract: 1485737 Copolymers of tetrahydrofuran BASF AG 15 Jan 1975 [16 Jan 1974] 1698/75 Heading C3R [Also in Division D1] Polyalkylene oxide adducts have the general formula R-X where R is the radical after removal of oxygen linked active hydrogen atoms of a C 8-22 alcohol or carboxylic acid or an oxyalkylation product thereof with 1-20 moles of ethylene oxide and/or propylene oxide; X is the radical of a copolymer of ethylene oxide and/or propylene oxide and tetrahydrofuran. The total amount of alkylene oxide units in R-X is 60-95% by wt. and the molar ratio of units derived from ethylene oxide and/or propylene oxide to units derived from tetrahydrofuran is 1 : 0À5 to 1 : 3. Typical examples are derived from oleic acid : ethylene oxide: tetrahydrofuran in weight ratios 1 : (1À5-2À5): (1À5-3). Uses.-Emulsifiers in the pigment dyeing of textiles.

    Abstract: 1415206 Textile-treating urea-formaldehydeglyoxal resins BADISCHE ANILIN- & SODAFABRIK AG 2 March 1973 [3 March 1972] 10214/73 Headings C3R and C3P [Also in Divisions D1-D2] A textile-treating resin is obtained by condensing urea with formaldehyde in a 1 : 2-10 molar ratio in aqueous solution at pH 7-10 and 20-80‹ C. for 0À5-4 hours, then at pH 31-5 and 20-100‹ C. until 5 drops of the solution produce turbidity in 10 ml. of 50% aqueous MgSO 4 .7H 2 O, then adding urea, glyoxal and optionally formaldehyde and heating at pH 5-7 and 20-60‹ C. for 1-6 hours, the final molar ratio of urea : formaldehyde : glyoxal being 1 : 1À5-2À5 : 0À3-0À6. In Examples 1-4 initial condensates of U : F ratio 1 : 4 are acidified with H 2 SO 4 or H.COOH to pH 3À5 to 4À8, heated at 35-90‹ C. for 20 mins to 4 hours and neutralized with NaOH; urea and glyoxal (and in Ex. 4 formalin) are added and the mixture heated at 50-55‹ C. for 3-4 hours; the U : F : G ratios of the products are 1 : 2-2À24 : 0À4-0À5. In Examples 5-7 cotton fabrics are treated with aqueous compositions containing the product of Ex. 2 or 3 and MgCl 2 alone or with a polyethylene emulsion or polyvinyl acetate/ starch mixture.

    Abstract: Now-woven fabrics are bonded by treatment both with an aqueous solution of a polyamine, polyalcohol or polyphenol and also with a solution (the solvent being one which is substantially insoluble in water) of an acid chloride which contains two acid chloride groups in the molecule; the sequence of the treatments with the two solutions is immaterial. Examples of the polyamines, polyalcohols and polyphenols are hexamethylene-diamine, tetramethylene-triamine, phenylene-diamine, ethylene glycol, glycerol, butanediol, butenediol, cyclohexanediol, neopentyl glycol and resorcinol. The acid chlorides used to react with these components are aromatic or aliphatic acid dichlorides such as the dichlorides of oxalic, malonic, succinic, glutaric, adipic, sebacic, maleic and terephthalic acids, or itaconic acid trichloride. Suitable solvents for these acid chlorides include hexane, heptane, cyclohexane, benzene, toluene, chloroform and trichloroethylene. Fibres which may be bonded by the above treatment include nylon 6, nylon 66, linear polyesters, acrylic fibres, natural fibres such as cotton and wool, and inorganic fibres such as glass or mineral wool. The preferred range of concentrations of the solutions with which the fabric is impregnated is from 1 to 10% by weight and impregnation may be effected by repeated dipping in a bath of the solution. Excess liquid may be removed by passage between squeeze rollers. Temperatures above atmospheric may be used if desired. Hydrogen chloride may be liberated by reaction between the two components and suitable alkalis may be included in the aqueous solution to prevent its escape. In Example 1 the aqueous solution contains 0.05% by weight of the adduct of 6 moles of ethylene oxide and 1 mole of p-isooctylphenol; in Example 8 the solution of acid chloride contains 10% by weight of p-hydroxybenzoic acid 2 ethylhexanol ester as plasticizer.

    Abstract: Fine fibres suitable for use in making papers, or cardboards are made by dissolving a polymer in an acid and reprecipitating it by diluting the acid solution with water with the use of a high shearing stress. In the example, polyhexamethylene adipamide is dissolved in sulphuric acid and the solution is dripped into water in a vessel provided with stirring means and baffles. After separation of the fibres, the diluted acid may be concentrated for reuse. Other acids referred to are hydrochloric, phosphoric and formic. Suitable polymers are polyhexamethylene - adipamide, polycaprolactam, polyacrylonitrile and polyethylene terephthalate. The fibres obtained may be processed alone or mixed with other natural or synthetic fibres on a paper-making machine to form non-woven fabrics, papers or cardboards. The fibres can be made to cohere by heating in the presence of water at temperatures below the softening points of the polymers.
