Title: Cellulose fibre product and the process of making the same
IPC: D06M15/11
Filed: 1927-04-30
Abstract: 270,335. Laucks. Inc., I. F., (Assignees of Davidson, G., Rippey, H. F., Cone, C. N., Laucks, I. F., and Banks, H. P.). May 3, 1926, [Convention date]. Adhesive sizes.-A size for paper, fabrics or other fibrous cellulose material comprises a dispersion of flour prepared as soya beans. Soya bean flour is prepared by grinding the cake left after the oil has been extracted. The flour, which contains about 45 per cent of proteins, is ground to pass a screen of two hundred meshes to the linear inch, and is dispersed in water, either wholly by mechanical means such as by treatment in a colloid mill, or by such means aided by the addition of caustic soda or other alkaline salts such as sodium borate, phosphate, sulphite or carbonate, or mixtures of sodium salts with lime. Alternatively, ammonia may be used, or copper and mercury salts. Manufactured paper or fabrics may be treated by dipping, pressing and drying. Oils or asphalt may be mixed with the size to render the sized material more pliable. After sizing, the material may be passed through a bath of formaldehyde solution, picric acid or tannic acid, this treatment rendering the colloids of the size insoluble and waterproofing the material. The sized fabric may be heated for the same purpose. In one example given, one part of soya bean flour is kneaded with two parts of water and agitated, then diluted with from five to ten parts of water. Sodium sulphite, sodium chloride or alum to the extent of one per cent of the weight of the flour may be added. In a further example, 10 parts of soya bean flour, one part of sodium fluoride, 75 parts of china clay and 125 parts of water are mixed and stirred, and the product used for sizing paper which is then hot pressed. A mixture containing 800 parts of soya bean flour, 120 parts of hydrated lime, 180 parts of resin, 16 parts of permanganate of potash, 60 parts of sodium fluoride, 80 parts of sodium carbonate, 16 parts of copper sulphate and 900 parts of water is used as a size. This mixture emulsified with a proportion of China wood oil may be used to form a waterproof coating on cloth or coarse fabrics. The Specification as open to inspection under Sect. 91 (3) (a) states that the flour may be prepared from other oleaginous seeds such as pea nuts, cutton seeds or linseed, and also that the composition may be used as a laundry starch or as an adhesive. This subject-matter does not appear in the Specification as accepted.

A copy of a graphic original is made by exposing a material comprising a support and a layer or layers in either order containing a light sensitive resin and a heat fusible waxy composition to visible or ultra-violet light which is reflected from or transmitted by the non-image areas of the original thus hardening the light sensitive resin, heating so that only the layers which received the minimum light exposure are softened and placing this heated material on a receiving sheet so that the softened portions are transferred to the sheet. If the exposure to heat and light is made simultaneously, a thin plastic sheet transparent to infra-red and visible radiation is placed between the original and the copying material. Specified heat fusible compositions are polyethylene glycols of the general formula: R-OCH2CH2O( CH2CH2O)nCH2CH2OR1 wherein R1 and R represent a hydrogen atom or an alkyl or aryl radical and n is at least 8, ferric stearate stearimide, chlorinated hydrocarbon wax, paraffin wax, carnauba wax, Japan wax and stearic acid. Specified light sensitive resins are polymers with side chains containing aromatic acids groups, e.g. polyvinylacetate-4-acidobenzoate and polyvinylacetate-3-acidophthalate and polymers containing olefinic double bonds e.g. polyvinylcinnamate. For preparing direct copies of the original, dyes or pigments which do not absorb in the infra-red region may be included in the light sensitive layer. Photosensitisers e.g.pyridine salt of 2-(-3-sulphobenzoylmethylene)-1-methyl-#-naphthothiazoline and 3-carbethoxy-7-methyl-4-oxo-1, 4adiacenaphthalene, may be added to decrease the time for light exposure. A printing plate may be used as the receiving sheet, the plate being placed on a duplicator and 500 impressions made (Examples 4, 8 and 11). Specifications 713, 947, 730, 451, 829,002 and 843, 541 are referred to.

Abstract: 268,979. Hiltner, R. S. May 3, 1926. Washing, materials and processes for.-A process for cleaning or scouring raw wool. animal fibres, feathers, furs, vegetable fibres &c. consists in treating the fibres with an intimate mixture or an emulsion of water and a water-insoluble solvent of grease, and agitating the mixture by mechanical means, the temperature being maintained below 160‹ F. Normally, no emulsifying agent is added, the substances present on the wool &c., being sufficient for this purpose, but if necessary, potassium carbonate, dilute ammonia, or the mixed potassium and sodium carbonates obtained from wool may be employed, together with such emulsifiers as extract of soap root, gums, glue, casein and potassium soaps. The prefered solvent is a petroleum distillate boiling between 175‹ C. and 225‹ C., but fractions passmg over at 75‹ to 125‹ may be used. Alternatively, coal tar distillates, chlorinated aliphatic or other hydrocarbons, esters, and ethers may be used. In operation, an intimate mixture is formed, by mechanical agitation, of the water and solvent, with or without the addition of the alkali or emulsifying agent, and this mixture is used to treat the fibre in a counter-current system. In general, about equal quantities of warm water and solvent are employed, with or without 0.1 per cent to 0.5 per cent of alkali to maintain neutrality or a slight alkalinity; a small amount of emulsifying ager ; may be used, and the temperature employed is below 160‹ F.
