摘要： A flexible, breathable laminate is provided for use in, for example, hospital gowns and the like, or tents. The article prevents liquids such as blood, alcohol and water from penetrating through internally while at the same time permits water vapor such as perspiration to pass out externally. The article comprises an inner layer of hydrophobic material and an outer attached layer of hydrophilic material containing a solid particulate or a liquid additive. For its intended uses, the article is fabricated possessing the following favorable combination of properties when compared to prior art materials: water vapor permeability, non-glare outer surface, bacteria barrier, comfort and/or drape, non-linting, liquid resistance, sterilizability and antistatic characteristics.

摘要： A rotor having at least one peripheral annular channel (24) is rotatable relative to a stator surface of a surrounding stationary housing to impel material in the channel from an inlet (28) through the housing, to a circumferentially spaced outlet (36), through which plasticised (liquid) material is discharged by pressure developed by the material being impelled against a first stationary surface (34) which projects into a channel downstream of the outlet (36). A second surface (40), upstream of the outlet (36), has a clearance with the walls of the channel (24) and restrains advance of (unmelted) material (39) in the centre of the channel while permitting liquid material (25) to be dragged towards the first surface (34). The channel space (46) between the first and second surfaces (34 and 40) enables the discharge pressure to be generated in an accumulated pool (42) of the liquid material. The second surface (40) may be provided on an extension along the channel of part of the member (32) which defines the first surface or may be provided on a further member (38), which may be of various different configurations, and may act as a scraper against one channel wall.

摘要： 1435845 Curing amine-curable polymers or prepolymers E I DU PONT DE NEMOURS & CO 14 Feb 1974 [14 Feb 1973 13 Aug 1973] 6777/74 Headings C3B C3P and C3R Amine curable polymers or prepolymers are cured by commingling the polymer or prepolymer with a dispersion of a complex of 4,4 1 - methylene dianiline and a salt selected from the nitrites and halides (except the fluorides) of sodium and lithium and sodium cyanide or a complex of racemic 2,3-di-(4-aminophenyl)- butane and a halide (except the fluoride) of sodium, potassium, rubidium or caesium in an inert liquid carrier, at least 90% of the particles of the complex in the dispersion having a diameter of not more than 60 microns, and effecting curing of the polymer or prepolymer. The polymer or prepolymer may be a polyurethane polymer containing free isocyanate groups, an epoxy resin, a halogen-containing hydrocarbon polymer, a chlorosulphonated polymer, a polymer containing acid halide groups, a polymer containing anhydride groups or an organopolysiloxane. Most preferably the complex is derived from 4,41-methylene dianiline and lithium chloride or sodium chloride. The inert carrier liquid must not promote rapid decomposition of the complex, must be unreactive toward the polymer or prepolymer and must be readily miscible therewith. Suitable inert liquids are di-(2-ethylhexyl)phthalate, a commercial aromatic process oil, and tetraethylene glycol bis-(2-ethylhexanoate). A surface active agent, e.g. lecithin may be included in the dispersion. Curing takes place by heating the reaction mixture to a temperature above the temperature at which the complex dissociates.

摘要： 1354746 Non-woven fabrics BAYER AG 7 July 1971 [11 July 1970] 31827/71 Heading D1R [Also in Division B2] A filter or artificial leather is produced by treating an unbonded fleece with a pre-mixed, reacting solution of a compound containing NCO groups plus a compound containing NH groups and/or a compound containing OH groups which yields 10 to 500% by weight of the fibres of a microporous polyurethane or polyurea which is insoluble in the solvent for the reactants, completing the reaction and simultaneously or subsequently removing the solvent by evaporation at a temperature below its boiling point. One or both sides may have a microporous, otherwise continuous surface layer of polyurethane. The fleece may be carded, air laid, spun bonded or wet laid, it may be stitched, and comprise polyester, polyamide polyacrylonitrile. polyvinyl chloride, polyvinyl acetate, polyvinyl alcohol, cotton, rayon, collagen or polyurethane fibres, or mixtures thereof. If the fleece contains smellable fibres it is wet with solvent before it is processed. The solution of reactants must be sufficiently concentrated for the polyurethane formed to enclose the solvent that has not evaporated during the reaction, so that the solvent leaves the polyurethane phases as dispersed pore-forming droplets and not as a continuous supernatant phase. In example 5 the polyurethane is prepared in a one stage process by stirring 30 gms of a partly branched polyethylene glycol adipate and 4.8 g di-(#-hydroxyethoxy)-benzene-(1,4), in xylene/dimethylformamide at 100‹C, adding 11 g 4,4'-diisocyanato-diphenylmethane and 0.1 g diazabicylooctane and stirring for 8 seconds. The mixture is poured over a polyethylene terephthalate fleece so that 2 mm. of solution stood over the surface of the fleece. In example 4 the above reacting mixture may be poured onto a hot glass plate. After 240 seconds a needled fleece of 70% polyamide, 20% bicomponent polyamide and 10% vinyl chloride/vinyl acetate copolymer adhesive fibres was placed on the coated glass plate and coated with similar solution. After the reaction has terminated and the solvent removed the product is split to give two fabrics each coated on one side. Example 2 describes treating a polyamide fleece with a similar reaction mixture, heating in ovens to complete the reaction and dry the product being specified. In example 3 a 2-stage polyurethane preparation comprised adding 2.4 g 2, 4 diaminotoluene in dioxane to 50 gm of a prepolymer from 500 g polypropylene glycol ether (OH number 56) and 125 g 4,4'-diisocyanato-diphenylmethane (2.8% NCO) in paraffin at 100‹C. After 3 seconds stirring the reacting solution was poured onto a 55% polyamide, 40% polyacrylonitrile and 5% regenerated cellulose fleece which was squeezed lightly with a glass rod and dried at 100‹C. The use of other 2 stage polyurethane preparations to bond and coat fleeces is described in examples 1 and 6. The Specification lists possible reactants and solvents, and specifies the water permeability and other physical properties of the products.
