IPC: D06M101/16
Filed: 1970-04-06
Abstract: 1,252,723. Synthetic suede. SUEHIRO SENI KOGYO K.K. 6 April, 1970 [30 June, 1969], No. 16209/70. Heading D1P. A synthetic suede sheet is formed from a homogeneous unitary composite structure of a napped knitted fabric containing at least 50 % of hydrophilic fibres and impregnated with 30-50% of a microporous polyurethane resin. The suede sheet is 0.5-1.0 mm. thick and the knitted fabric is either warp or weft knitted. The hydrophilic fibre may be of cotton, viscose rayon, viscose stable or cupra. The base knitted fabric may also contain <50% of other artificial fibres, e.g. nylon, acrylic fibre, polypropylene fibre which can be knitted or spun with the hydrophilic fibre for reinforcement. The polyurethane resin, of M wt. 50,000-70,000, may be of a straight chain prepolymer of 4-4' diphenyl methane diisocyanate (MDI) and polyole (high M wt. compound containing active hydrogen) or a straight chain prepolymer of tolylene diisocyanate (TDI) (a mixture of 80% of 2.4-TDI and 20% of 2.6-TDI) or a blended polymer of MDI and TDI. The polyurethane resin may contain <30% of polyvinyl chloride or acrylic polymer. The solvent for polyurethane resin is a water compatible solvent, e.g. N-N dimethylformaldehyde, N-N dimethylacetoamide, N-N diethylformamide, dimethylsufoxide, dioxane, tetrohydro furane or mixtures of these. The napped knitted fabric is treated, at 20-30‹C, with a solvent soluble in water containing #10% by weight of resin solution of polyurethane polymer. The fabric is then squeezed by rolls to leave 30-50% of resin, based on the weight of knitted fabric and then the fabric is passed through a bath of water at 5-15‹C causing the solvent to diffuse and dissolve in the water the resin impregnated in the fibres to coagulate, forming a homogeneous composite structure. The composite structure is then washed with water, dried at 138-162‹C to set the resin and finally polished. Advantageously the coagulation in cold water is carried out in 2 steps; (a) the squeezed knitted fabric is passed, under no tension, through a first bath of water at 5-15‹C and while being subjected to a slight vibration perpendicular to the plane of the fabric and (b) the fabric is passed through a second bath of water at 5-15‹C. while the width of the fabric is increased by means of a tenter.

Abstract: 1,266,259. Centrifugal separators. OTTO DURR K.G. 25 March, 1970, No. 14546/70. Heading B2P. An apparatus for cleaning a gaseous medium having particles, e.g. of paint or dust, therein, comprises a chamber 31 defining a substantially ring-like path, a rotary impeller 21 for passing the gaseous medium through the chamber and for imparting to the gaseous medium in the chamber a vortex rotation about the whole of the ring-like path thereby separating the particles from the medium by centrifugal force and an opening 34 for removing the gaseous medium from the whole of the ring- like path. As shown, air containing paint particles passes from a paint-spraying bath 10 through a grate 11 and water screens 42, 43 and enters the rotating impeller 21 axially via a duct 24. Whilst rotating, the air enters the annular chamber 31 tangentially, being thereby induced into a helical vortex rotation X 5  around the path defined by the chamber. From the chamber the air passes outwards via the opening 34 into an outer annular chamber 33 where, as a result of its tangential entry and a guide wall 29 it is imparted a vortex rotation X 6  of opposite direction to vortex rotation X 5 . The air then passes into a chamber 37 and after passing around a wall 36, through a screen 41 and around a deflecting wall 40, discharges through an exhaust pipe 39. Under the action of the vortex rotations X 5 , X 6 , the heavier paint particles are centrifuged out and drop into a collecting water trough 15. The remaining particles separate on the walls 36, 40 and at the screen 41 and fall on to a partition wall 25 from where they flow, e.g. through discharge pipes, to the collecting trough 15. More than two series-connected annular chambers 31, 33 may be provided and several separators or impellers with associated annular chambers may be connected to the same watercollecting trough and/or exhaust into a common exhaust pipe.
