Abstract: A process for the preparation of a high molecular weight polymer by a condensation process of a liquid reaction mixture wherein at least one volatile by-product is eliminated, characterized in that said condensation process is carried out in apparatus of such form and so operated that said reaction mixture being subjected to the condensation process has no free surface and removal of volatile product or products from said reaction mixture is effected by diffusion through at least a proportion of the wall of said apparatus which is permeable to said volatile product or products but not permeable to said reaction mixture or said polymer, said proportion of the wall which is permeable serving to separate said reaction mixture from a chemically inert gaseous fluid in which the partial pressure of the volatile byproduct, or of the volatile by-products, is continually maintained below the equilibrium partial pressure for the reaction mixture under the conditions of reaction.

Abstract: A machine for producing stitch bonded fabrics comprising means for supplying a layer of warp threads, means for continuously supplying a weft thread, means for supplying a plurality of stitching threads and means for stitching the warp layer and weft thread together with said stitching threads, the improvement being that the means for supplying and laying the weft thread consists of a pair of closely spaced plates, means for forwarding an individual thread towards the plates and means for imparting an oscillatory motion to the forwarded thread before it passes between the plates.

Abstract: Film- or fibre-forming polyesters are made by polycondensing a glycol ester of a dicarboxylic acid or low molecular weight polymer thereof in the form of liquid droplets of diameter 0.5 to 1000 microns, the droplets being exposed to a relative motion in a chemically inert gaseous fluid. The droplets may be allowed to fall freely through the gaseous fluid (e.g. in a vertical tower) or the gaseous fluid may be in the form of an upwardly moving stream. The partial pressure of glycol in the gaseous fluid is kept at a low value, e.g. by contacting the gaseous fluid with a condensing surface or by purging a proportion of the gaseous fluid and replacing it by fresh gaseous fluid. Specified glycol esters are the ethylene glycol ester of terephthalic or 1:2-diphenoxyethane-4:41-dicarboxylic acids (alone or in admixture with adipic or isophthalic acid). An example describes the preparation of polyethylene terephthalate.

Abstract: A process for the production of thermally segmentally bonded non-woven fabrics by calendering between rolls at least one of which bears a pattern formed by groups of lands of different density, the difference in density resulting, for example, from grouping lands of different sizes of different numbers per unit area.
