Title: Fabric for Sacks and Bags.
IPC: D03D3/00
Filed: 1967-07-05
Abstract: 1,176,078. Woven or non-woven fabric for sacks. SAKAI KASEI KOGYO K.K. 5 July, 1967 [6 July, 1966], No. 31073/67. Headings D1K and D1R. Sacking is made from strips slit from synthetic sheet which has been re-heated and stretched to six or nine times its original length. Two layers of the strips, disposed at right angles to each other, may be bonded together, or the strips may be used as warp and weft in a woven fabric (the strips being kept flat). The fabric may be roughened by applying adhesive and scattering grains of synthetic material on it to prevent the sacks from slipping when stacked. In the case of woven fabric, the sheet may be roughened before slitting to prevent the warp and weft from slipping.

Abstract: Vinyl chloride is interpolymerized with an acid or amide of the acrylic or a -b -unsaturated-a -b -dicarboxylic series, with or without a further water-insoluble substance polymerizable under the same conditions, the said acid or amide in the interpolymer amounting to 0,5 to 3 per cent of the product, and the interpolymer is heated with a dilute solution of a strongly alkaline substance, and then washed.  Acids specified are acrylic, a -methacrylic, a -chloracrylic, and maleic acids.  Additional polymerizable substances specified are vinyl esters, acrylic esters, acrylic nitrile, and styrene.  The polymerization may be carried out in mass in aqueous emulsion, in solution, or in the presence of a liquid solvent for the monomer which is a non-solvent for the polymer, and there may be added plasticizers, dyestuffs, pigments, and fillers.  In examples: (1)--(3) vinyl chloride is emulsified in an aqueous solution of hydrogen peroxide and sodium a -hydroxy-octodecane-sulphonate and (1), (2) acrylic acid mixed with acrylic methyl, ethyl, butyl, iso-octyl ester added in portions, (3) acrylic, a -methacrylic, or maleic acid added, the mixture warmed, and the polymer precipitated by aluminium sulphate, heated with dilute caustic soda solution, and washed; (4) vinyl chloride is emulsified in an aqueous solution of ammonium persulphate, sodium pyrophosphate, and turkey red oil, methacrylamide added, and the mixture warmed, and the polymer worked up as in examples (1)--(3).  A sample has been furnished under Sect. 2 (5) prepared as follows: vinyl chloride and maleic acid are emulsified in an aqueous solution of potassium persulphate and sodium a -hydroxy-octodecane sulphonate, the mixture warmed, and the polymer worked up as in the examples.  Specifications 376,479 and 376,481 are referred to.  The Provisional Specification refers to the interpolymerization with vinyl chloride of unsaturated carboxylic acids in general and additionally specifies itaconic acid.

Abstract: 968,974. Winding plurality of strands on tubes. PITTSBURGH PLATE GLASS CO. Aug. 12, 1963 [Nov. 13, 1962], No. 31717/63. Heading D1J. A plurality of strands are wound upon a single tube and are traversed in such manner that the strands alternately cross and are laterally spaced from each other in the form of a repeated figure of eight. Two multifilament glass strands 26, 28 pass, one in front of and one behind a rotating traverse roller 36 to a winding tube 20. The traverse roller 36 has two oppositely handed cam portions each extending approximately 180 degrees around the roller (Figs. 4-7, not shown), which serve to distribute the strands in the repeated crossover relation shown. Distribution of the thus laid strands over the axial length of the tube 20 is achieved by causing either the tube 20 or the roller 36 or both to reciprocate in relation to each other, The relative rotational speeds of the roller and tube are selected to ensure that the strands cross at a substantial angle to each other. The crossover winding pattern is stated to prevent adhesion of one strand to the other and to facilitate unwinding.
