Title: Polyisocyanate modified polyesters or polyesteramides
Inventor: COFFEY DAVID HAY
IPC: C08G18/12
Filed: 1954-01-18
Abstract: A composition comprises (a) 40 to 5 per cent by weight of a rubbery organic di-isocyanate modified linear polyester or polyesteramide, and (b) 60 to 95 per cent by weight of a crystalline linear polyester or an organic di-isocyanate modified crystalline linear polyester. The polyester or polyesteramide used for making the rubbery ingredient preferably has a molecular weight of 1000 or more and is made by reacting a glycol (e.g. ethylene-, propylene- or butyleneglycols), a dicarboxylic acid (e.g. succinic, glutaric, adipic, methyl adipic, pimelic or phthalic acid) and if desired a diamine (e.g. ethylene or hexamethylene diamine) or an alkylamine (e.g. monoethanolamine or propanolamine).  One mol. of the polyester or polyesteramide is reacted with 1.0-1.2 mols. of the diisocyanate. The crystalline polyester is made by reacting a glycol (e.g. ethylene-, tetramethylene- or hexamethylene glycol) with a dicarboxylic acid (e.g. succinic, adipic, suberic, sebacic or terephthalic acids) and if it is to be reacted with a di-isocyanate (e.g. hexamethylene-, toluylene -, p - phenylene -, 4:41 - diphenylmethane- or naphthalene-di-isocyanate), 1.0-1.2 mols. of di-isocyanate are used per mol. of polyester.  The crystalline polyester or di-isocyanate modified crystalline polyester preferably has a molecular weight of greater than 10,000.  In examples (1) a polyesteramide derived from adipic acid, ethylene glycol and monoethanolamine) is modified with hexamethylene di-isocyanate and mixed with a hexamethylene di-isocyanate modified polyethylene sebacate to give a composition which may be compression moulded; (2) a naphthylene diisocyanate modified polyethylene adipate is mixed with polyethylene sebacate to give a composition which may be compression moulded.

Title: A process relating to the dewaxing, desizing and partial bleaching of goods containing cotton
Inventor: WHITE WILFRED ARTHUR STEPHEN
IPC: D06L4/70
Filed: 1953-01-20
Abstract: A multi-stage process for the dewaxing, desizing and partial bleaching of cottoncontaining goods prior to dyeing, printing or other finishing processes comprises the steps of continuously and rapidly passing the goods, preferably in open width, through a bath of a hydrocarbon or chlorinated hydrocarbon solvent and treating the goods with a bath of an aqueous alkaline solution of a peroxygen compound.  The treatments may be effected in either order.  The organic solvent may be at its boiling point and the goods may be squeezed at intervals during their passage through the solvent bath; the peroxygen bath also may be hot.  The goods may be passed through two consecutive baths containing the solvent or may be passed through a bath containing the solvent and a system of rollers such that during their passage through the bath the goods are raised above the level of the liquid five times.  The solvent retained in the goods may be removed by drying or may be flashed off by passing the goods through hot water, and may be subsequently recovered, the excess water being removed from the goods by mangles.  The solvent may be chloroform, methylene chloride, ethylene trichloride or perchlorethylene.  The goods may be subjected to a prolonged immersion in the aqueous bath or to a rapid impregnation, e.g. by padding, followed by steaming.  Following the aqueous bath the goods may be rinsed several times, one of the rinses containing an acid. Goods which have been steamed after the aqueous bath may be kept hot up to a washing and rinsing step.  The peroxygen compound may be unneutralized sodium peroxide, sodium percarbonate, sodium perborate or hydrogen peroxide and the aqueous bath may also contain sodium silicate and a condensation product of octyl cresol and ethylene oxide.  The pH of the bath may be adjusted to 11-12 with alkali.  The goods may be woven piece goods, loose fibre stock, yarn or knit goods and may comprise mixtures of cotton with viscose rayon.  The aqueous bath for treating such mixed fibre goods may also contain sodium bicarbonate.

Title: Improved means for winding and aftertreating fresh-spun artificial silk
Inventor: GRAUER THEODOR
IPC: B65H54/54
Filed: 1951-01-23
Abstract: 714,494. Bobbins and supports therefor during winding. FELDMUHLE AKTGES. Jan. 23, 1951, No. 1683/51. Classes 120(2) and 120(3) A means for winding and after treating fresh-spun artificial silk comprises two axially telescopable parts, of which the outside one is a double-flanged winding bobbin and the inside one serves as a bobbin holder during the winding operation, the said bobbin holder having radially spreadable flat bars extending through longitudinal slots in the winding bobbin, which bars are spreadable by means of incline faces thereon engaged by an axially slidable member provided with conical surfaces and is characterized in that the axially slidable coned member is acted upon by a main helical compression spring to effect the radial spreading of the bars, said main spring being itself acted upon by a bush slidable upon a supporting axle for the bobbin, and said bush being adapted to be held in lock ing position by a second compression spring weaker than the main spring. As shown the bobbin comprises two flanges 1 and 2 interconnected by a longitudinally slotted barrel 3. The holder comprises a plurality of movable bars 4 which can be made to protrude through the slots in barrel 3 by the axial movement of a member 16 on an axle pin 15 in one with a hub 6 which, by means of a set screw 8, can be mounted on a driving spindle 7 of a winding frame. When the member 16 is pushed towards hub 6 the wedge faces 12a and 13a engage the bars 4 and push them radially outwards and when it is pulled in the opposite direction the wedge faces 14a engage the bars 4 and pull them inwards. Movement of member 116 is controlled by a knob 17, through a bush 21 and pin 18 with intervening springs 26 and 30. A ball 22 which engages a recess in the axle-pin 15 locks the bush 21 in its "in" position, thus keeping the bars 4 in their "out" position whilst "winding" takes place. When winding is completed the knob 17 is pulled " outwardly," thus releasing the ball 22 and therefore the bush 21 which moves "outward" under the action of the springs, thus withdrawing the bars 4 and leaving a package of artificial silk loosely wound on the bobbin, which can then be removed from the holder and the package subjected to any after-treatment necessary. Specifications 339,820, [Class 120(ii)], and 541,284 are referred to.
