Title: Improvements in or relating to the moth-proofing of wool
Filed: 1951-08-30
Abstract: 695,168. Moth-proofing. ERIKSSON, E. B. Aug. 30, 1951. [Sept. 1, 1950; May 15, 1951] No. 20480/51. Class 140. Wool which may have been dyed in an acid bath is rendered moth proof by treating in an alkaline bath containing an excess of alkali, rinsing in water so that all acid residues fixed to the wool are neutralized and removed, and then treating in a solution of silicon fluoride whereby the silicon fluorides are firmly fixed to the wool. The treatment with silicon fluorides may take place in a dyeing bath which contains only small quantities e.g. 1 to 2 per cent by weight of the wool of acid. After treatment in the silicon fluorides the wool may be dyed in a dyeing bath at a pH not less than 3.0. The moth-proofing and dyeing may be carried out simultaneously. in a dye bath containing silicon fluorides and small quantities of acid not exceeding 2 per cent by weight of the wool. Further treatment in a bath containing ordinary soaps of fatty acids after the silicon fluoride bath improves the fixation effect. In one example a strip of white woollen fabric weighing 30 grams was dyed by boiling for 2 hours with 3 per cent neulan-dye-stuff (neulan red GRE) in a dye bath containing 8 per cent.sulphuric acid and 10 per cent crystallised sodium sulphate by weight, after which the fabric was rinsed in running water for 30 mins and then treated for 10 mins at room temperature in a solution containing 0.05 normal ammonia at a bath ratio of 1 : 25 between material and liquid, rinsed for 5 mins in running water and treated for 20 mins at a temperature of about 25C in a solution containing 3 per cent ammonium silicon fluoride calculated on the weight of the material at a bath ratio of 1 : 25, finally rinsed in running water for ten minutes and dried.

Abstract: 954,204. Orienting and heat-setting polymeric film. MINNESOTA MINING & MANUFACTURING CO. June 15, 1960 [June 15, 1959], No. 21072/60. Addition to 922,481. Drawings to Specification. Heading B5B. The process of the parent Specification (wherein a crystallizable film of synthetic organic thermoplastic material that has previously been oriented by stretching at least in the longitudinal direction is further oriented and simultaneously heat-set by continuously stretching a web of the film in the longitudinal direction while the film is heated to above 150‹ C. and below the melting-point of the film, and quenching the film before releasing the tension of stretching) is modified in that the film consists of a linear condensation superpolymer and is further oriented and simultaneously heat-set by feeding a web of the film at constant input speed into contact across its width with each of a series of parallel smooth-surfaced cylindrical guide rolls, each rotatable about its axis, with the web following a sinuous path over and under alternate rolls, heating the web in contact with the first of the rolls to a temperature within 30 ‹ C. of but below its sticking point, quenching the web while it is in contact with the last of the rolls, and pulling the quenched web from the last roll at a constant output speed of at least 1.2 times the input speed. The tangential distance between consecutive rolls in the series may be from 0.5 to 2.0 inches. The film may be a polymethylene terephthalate, such as polyethylene terephthalate, and in the latter case the temperature may be 215‹ to 235‹ C. The film may be pulled from the last of the rolls at or about at its natural draw ratio. The film may be heated to about 100‹ to 175‹ C. under no tension after it has been pulled from the last of the rolls. The previous orientation of the film may have been effected by stretching at a draw ratio of 2.5 to 3.25 'n each of the longitudinal and transverse directions. The " sticking point " is defined as the lowest temperature at which the optical surface of the oriented film is marred if stretched momentarily against a polished brass surface and peeled therefrom.
