Abstract

1447889 Cured novolak fibres TORAY INDUSTRIES Inc 10 Dec 1973 [11 Dec 1972] 57101/73 Heading B5B [Also in Division C3] A fibre group, e.g. yarns, woven and non- woven textile fabrics, bundles and sheets, comprises a number of cured phenol-formaldehyde novolak resin fibres at least 80% of which have a yield point, which is generally at 3-10% elongation. The cured novolak resin fibre group may contain up to 30% wt. of a linear polymer other than a novolak resin, e.g. a polyamide, polyester, polyurea or epoxy resin. The cured fibre group may be prepared by curing, preferably at 30-95‹ C., an uncured fibre group containing novolak resin fibres having a degree of orientation of at least 0À25 and which may have a molecular weight of from 550-750, in the presence of an acid, such as HCl, H 3 PO 4 , U 2 SO 4 or a sulphonic acid, and a source of formaldehyde, such as formalin, tetraoxymethylene, a xylene resin or trioxane, and optionally in the presence of a curing accelerator such as aniline, bis-p-aminodiphenylmethane or meta-xylylene diamine. The uncured fibre group is preferably obtained by spinning a composition containing a novolak resin according to the following equation at a ratio of take-up speed to output linear speed of at least 500: where # is the melt viscosity (poises) of the resin at 150‹ C., # is the logarithmic viscosity of the resin in ethanol at 25‹ C., and α is a constant. In Examples 1-38 a phenol-HCHO novolak resin or a blend of the novolak resin and either a polyester, a polyurea, an epoxy resin or a polyamide (various nylons disclosed) was spun into filaments and the resulting fibre bundle cured by heating in a solution of HCl and formalin. In Example 39 a phenol-HCHO novolak resin was melt-blended with tetraoxymethylene and bis-p-aminophenylmethane and spun into filaments. In Example 40 a blend of a novolak resin and nylon 6 was spun into filaments and cured by heating in a solution of H 2 SO 4 and formalin.
