Patent GB-991230-A (GB)
Title: Improvements in and relating to textile yarns
IPC: D02G1/02
Filed: 1963-11-15
Abstract: In the production of crimped yarn, at least one blended spun yarn of "non-thermoplastic" fibres and thermoplastic fibres in an amount of at least 10% and not more than 90% by weight based on the total weight of the yarn is temporarily highly twisted e.g. by false-twisting, in the same or opposite direction as or to the spinning twist, and heat-set using dry heat at a temperature of at least 150 DEG C., and may then be partially untwisted with or against the spinning twist.  The non-thermoplastic fibres may be of natural cellulose such as cotton, regenerated cellulose, wool or silk, and the other fibres may be of a cellulose derivative such as cellulose acetate or a synthetic polymer e.g. polyamide, polyester, vinyl polymer or copolymer, polyolefin.  Heat-setting may be accomplished by passage of the yarn through a tube containing an electric heating coil or by contact with a heated metal surface.  The blended yarn may be impregnated before or during the high-twisting with a solution of a condensable resin-forming substance e.g. a methylol compound of urea, a urea derivative or melamine.  After the high twisting, the yarn may be treated with an alkali solution of mercerizing strength and/or two or more yarns may be plied.

Abstract: 1,206,394. Moulding by electrostatic deposition. BRITISH URALITE Ltd. 24 Oct., 1967 [24 Oct., 1966], No. 47703/66. Heading B5A [Also in Division F2] An article formed from a fibrous material and a particulate binder which can be treated to bond the fibres together is made by applying an electrostatic charge to the fibres and binder particles, positioning an earthed or oppositely charged former so that the material is attracted to and collects on its surface, wetting the deposited material during formation of the coating, treating the deposited material to bond the fibres together and removing the article from the former. The fibre is preferably asbestos and the binder Portland cement or bitumen, the binder being damped or heated respectively to form the finished article. Plastics articles can also be made using polythene, polyvinyl chloride or expanded polystyrene particles and nylon or cellulose fibres; magnesium orthotitanate or chalk being added as filters and to help dispel the repulsive charges between the plastics particles on the former. The articles are formed by heating and the former may be heated during the deposition. The electrostatic charge is generated by corona discharge, by charging the nozzle through which the material is dispelled or by mixing the material with an ionized gas. Working voltages are at least 15 kV D.C., pulsed D.C. or A.C. superimposed on D.C.  As shown, for the manufacture of an article from asbestos fibres and Portland cement powder, the former 23 is rotated by motor 4 and may be moved axially by pistons 7, 8, 9. The former 23 is earthed and corona discharge electrodes 3 comprising multiple needles mounted on a metal bar are connected to an E.H.T. source. The discharge apparatus is mounted in a compartment 2 insulated from the rest of the apparatus. The fibre, cement mixture is fed into the discharge via nozzle 13 supplied from hopper 10. Box 14 contains a water spray from nozzle 15 and has sliding doors 16, 17 through which the article can be removed. In operation, the ram 9 is extended and the former is filtered outside doors 16, 17. The former,is then rotated and reciprocated in the corona discharge while material is fed in. The discharge is switched off and the rotating former is passed to the box 14 where the coating is wetted. The process is repeated until the desired thickness has been built up and the coated former is then discharged through doors 16, 17. The asbestos and cement may be sprayed together or alternately to form separate layers.
