Abstract

A process for the production of finely divided particles whose state of subdivision is such that they possess a high water-retaining capacity and are readily dispersible in water, of synthetic linear polyamides and polyesters comprises incorporating in a gel of the polymer sufficient of a mineral salt or organic colloid which is soluble in an aqueous medium to give a consistency between that of a pulp and that of a powder dispersing the mixture so obtained in an aqueous medium which can bring into solution the said salt or colloid with or without chemical reaction taking place, and separating from the aqueous medium the fine particles of the polymer so formed. Specified mineral salts and organic colloids are sodium chloride, sodium sulphate, gelatine, carboxymethyl cellulose and alginates. In the examples, particles are made from: (I) and (III) an aqueous alcoholic gel of an interpolyamide of e -caprolactam and hexamethylene diammonium adipate; (II) and (IV) an aqueous alcoholic gel of an interpolyamide of e -caprolactam, hexamethylene diammonium adipate and hexamethylene diammonium sebacate; (V) an aqueous methanol gel of the interpolymer of Ex. (II); (VI) a gel in methylene chloride of an interpolyester derived from ethylene glycol, hexahydroterephthalic acid and terephthalic acid and (III) a gel in methylene chloride of an interpolymer derived from ethylene glycol, terephthalic acid and sebacic acid, the polyamide particles being mixed with polyhexamethylene adipamide fibres and felted and the polyester particles being mixed with polyethylene terephthalate fibres and felted.ALSO:A process for the production of felted products comprises forming an aqueous suspension of fibres containing as binder, finely divided particles of synthetic linear polyamides or polyesters (see Division C3), forming a felt from the said suspension, and heating the felt at least to the melting temperature of the bonding particles. In the examples, felts are made from 1: (I) and (III) polyhexamethylene adipamide fibres and particles of an interpolymer derived from hexamethylene diammonium adipate and S -caprolactam; (II), (IV) and (VI) polyhexamethylene adipamide fibres and particles of an interpolymer derived from S -caprolactam, hexamethylene diammonium adipate and hexamethylene diammonium sebacate; (VI) polyethylene terephthalate fibres and particles of an interpolymer of ethylene glycol, hexahydroterephthalic acid and terephthalic acid and (VII) polyethylene terephthalate fibres and particles of an interpolymer of ethylene glycol, sebacic acid and terephthalic acid.
