Title: Fusion and regranulation of thermoplastics from bulky textiles - using a gravity loaded heated metal block die
IPC: B29B17/00
Filed: 1974-06-17
Abstract: Reclamation of thermoplastic textile materials is by loading scrap fabrics or yarns into a vertical chamber for compaction by a gravity plunger against a concave base which is hot enough to melt material in contact with the surface. The base is perforated to allow molten material to extrude as strands which may be quenched and chopped to recover material in a granulated form. Pref. the outlet channels have conical entry angles of approx. 60 degrees with a mouth to root dia. ratio of approx. 2:1. The block temp. should be measured for thermostatic control. Suitable for accepting materials with a low bulk density as fabrics or filaments. Intrinsically more efficient than processes which degrade the material back to monomer or oligomer form requiring repolymsn. prior to re-use. There is no risk of local overheating of material, since the block temp. is the max. temp. involved.

Patent FR-2326177-A1 (FR)
IPC: A61K8/81
Filed: 1976-09-30
Abstract: Setting lotions based on polyvinyl resins, specifically polymers and copolymers of vinylpyrrolidone, yield on addition of cationic, in particular polyquaternary, resins non-sticky films. Polyquaternary resins are far more effective as additives than cationic detergent raw materials. The great efficacy of the quaternary resins makes it possible to dispense with the addition of hardeners even when the basic resin used is the PVP with an average molecular weight of about 40,000 which is particularly sticky and therefore scarcely used in countries where the humidity is sometimes very high. A setting lotion of this type is free of organic solvents but, nevertheless, yields non-sticky films. It is, moreover, in the form of a powder and is made ready for use by dissolving or dispersing in water without further additives.
