| abstract | 552,130. Yarns and threads. BRITISH CELANESE, Ltd. Sept. 19, 1941, No. 12077. Convention date, April 2. [Class 120 (iii)] [Also in Group IV] Yarns or fibres of a thermoplastic material are associated with yarns or fibres of a relatively non- thermoplastic material to form a composite yarn, cord, braid or like textile product which is then subjected to the action of vapours of a softening agent for the thermoplastic material so that without stretching the yarn or subjecting it to lateral compression, the thermoplastic material is caused to soften and to bond together the non-thermoplastic yarns or fibres. The thermoplastic material may be a cellulose derivative, a polyvinyl compound or a synthetic linear polyamide. The non-thermoplastic yarns may be of cotton, linen, silk, regenerated cellulose, or of stretched and then saponified cellulose esters, or they may be made of staple fibres having a basis of a cellulose derivative or linear polyamide, blended with non- thermoplastic fibres to give a yarn which is in part thermoplastic. Yarns of non-thermoplastic material may be wound or braided about a core yarn of a thermoplastic material or the core may comprise non-thermoplastic textile material which has wound about it a thermoplastic yarn and the remaining non-thermoplastic yarns may be twisted or braided about the core yarn. Both core and windings may comprise yarns made by spinning a mixture of cotton fibres and cellulose acetate staple fibres. The thermoplastic yarns or fibres may be treated with a plasticizer prior to being twisted or associated with the non-thermoplastic yarns, or the composite yarn may be treated with a plasticizer e.g. an emulsion or solution of methoxy ethyl phthalate, triethylene glycol, ethyl phthallyl ethyl glycollate, B-trichlorethyl phosphate, or ethyl-p-toluene sulphonamide. The plasticized yarn may be aged to ensure proper penetration of the plasticizer. The solvent or softener may be acetone, acetone and water, ethyl alcohol, diacetone alchohol, ethylene dichloride, chloroform, methyl chloride and methyl or ethyl alcohol, or dichlorethylene. In an example, a cellulose acetate yarn is wound about a cotton yarn to form a core yarn. Several cotton yarns are twisted about this core yarn to form the composite yarn which is then subjected to treatment with warm acetone vapour to coalesce the cellulose acetate yarns and bond the assembly into a compact unitary structure. In another example the composite yarn comprises several stretched saponified cellulose acetate yarns braided about a core yarn of cellulose acetate. |
