    Abstract: 1,224,255. Nylon filaments. TORAY INDUSTRIES Inc. 2 July, 1968 [4 July, 1967; 8 July, 1967 (2)], No. 31626/68. Heading B5B. Nylon 6 filaments are produced which satisfy the following conditions:- #=35Œ5 degrees, and 0À50 # I M /I P # 0À89, where 8 is the angle formed by the meridian and the straight line drawn from the intersection of the meridian and the equator line toward the point indicating a maximum strength in the X-ray low-angle interference image; I P is the interference strength at the point indicating the maximum strength; and I M is the interference strength at the point where a straight line drawn parallel to the equator line from the point indicating the maximum strength intersects the meridian; and a relation between tenacity and breaking elongation is given by:-S x E # 207À0 and 15 #E # 35, where S is the tenacity of the filament in g./denier and E is the breaking elongation of the filament in per cent. Preferably S # 9À2. The method comprises melting nylon 6 chips having a relative viscosity over 2À9 with respect to sulphuric acid and extruding the melt through a spinneret to form filaments which are rapidly cooled to coagulate them, the filaments are then drawn successively in at least 3 stages at such a rate that in the early drawing stages no measurable birefringence is observed and in the later stages the filaments are drawn to the desired final drawing ratio. The time for cooling and coagulating to the start of the drawing process is preferably less than 10 seconds. Also during at least one intermediate drawing stage the content C 8 of the 8-form crystal structure of the filament should preferably be in the range 0À65 # C 8 # 0À90. The nylon 6 filaments can be used to make yarns for tyre cords.

    Abstract: The electrostatic recording material comprises an electroconductive transparentized base sheet having a dielectric layer thereon. The transparentized base sheet is obtained by subjecting to a transparentizing treatment with moisture, heat and pressure a fibrous matrix sheet of a mixture of natural pulp with synthetic pulp formed of a blended polymer system consisting essentially of polyvinyl alcohol-acrylonitrile copolymer and acrylonitrile-styrene copolymer.

    Abstract: 1339181 Phenol-formaldehyde fibres TORAY INDUSTRIES Inc 1 Oct 1971 [2 Oct 1970 23 Dec 1970 13 April 1971 4 May 1971] 45751/71 Heading C3R [Also in Division B5] Cross-linked phenol-formaldehyde fibres are prepared by mixing a novolac resin having a pH of at least 4 with tetraoxymethylene and/or trioxan, melt-spinning the mixture to yield fibres and then curing in the presence of an acid catalyst preferably at a temperature of 0-150‹ C., preferably followed by a heat treatment, at 70-250‹ C. The phenolic component of the resin is preferably phenol or bisphenol A. Suitable acid catalysts include mineral acids, Lewis' acids, sulphonic acids, organic carboxylic acids, acid precursors and acid salts. The catalyst may be used in conjunction with formaldehyde and/or a compound producing formaldehyde. The fibre may be modified by reaction with a compound other than HCHO during or after the curing process to block and/or cross-link the phenolic hydroxy groups. The modifying compound may be the same as the acid catalyst. Suitable modifying compounds include acid halides ; acid anhydrides; a compound of the formula R-(COX) n wherein R represents a C-C bond, a di-, tri- or quadrivalent acyclic hydrocarbon or an aromatic radical, n = 2-4 and X is a halogen atom; a compound of the formula R-(X) n wherein R represents -CO-, -Si(R 1 ) 2 -, -P(R 1 )-, -P(O)R 1 )-, -O 2 S-R 2 -SO 2 -, -P-(-R 1 ) 3 - or wherein R 1 is a halogen atom or an organic group such as alkyl, phenyl, alkoxy or phenoxy, n > 2, and X is a halogen atom, and R 2 is phenylene, where Z is -O-, -S-, -CH 2 -, -CO-, When the modification treatment is effected with an halogenated phosphorus compound the fibres are subsequently stabilized by reaction with an epoxy compound such as propylene oxide. In Examples 1 and 2 fibres prepared from a mixture of a phenol-HCHO novolac resin and 10% wt. tetraoxymethylene or trioxan are cured by heating in the presence of one of the following acid catalysts: H 2 SO 4 , PCl 3 , p-toluenesulphonic chloride, oxalic acid, acetyl chloride both in the presence and absence of HCHO. In Example 5 cross-linked fibres are prepared from novolac resins prepared from formaldehyde and (i) a mixture of phenol and p-cresol, (ii) bisphenol A, (iii) phenol, aniline, (iv) phenol, nylon 6 by melt spinning the resins with 10% wt. tetraoxymethylene and then curing the fibres in the presence of p-toluene sulphonic acid. In Example 6 fibres melt spun from a phenol-HCHO novolac and 10% wt. tetraoxymethylene mixture are cured in the presence of HCl and HCHO and then heat treated in the presence of acetic anhydride and one of the following catalysts: p-toluene sulphonic acid, HCl, BF 3 etherate, acetyl chloride, dimethyl formamide hydrochloride, and oxalic acid. In Example 7 fibres prepared from the resin of Example 1 are cured in the presence of various acid chlorides and subsequently heat-treated. In Example 8 fibres are melt spun from the resin mixtures of Example 5 and cured in the presence of one of the following modifying compounds: succinyl dichloride, fumaric acid dichloride, butenetetracarboxylic acid tetrachloride, benzophenonetetracarboxylic acid tetrachloride, naphthalene - 1 - 5 - dicarboxylic acid dichloride, oxalyl chloride, butenetricarboxylic acid trichloride, maleic acid dichloride, isophthalic acid dichloride. In Example 9 fibres melt spun from a mixture of a phenol- HCHO novolac resin and 10% wt. tetraoxymethylene are reacted with various halogenated phosphorus compounds and subsequently stabilized by reaction with propylene oxide.
