Class 142(4) [Also in Group XXVIII] The woven outer jacket of a hose pipe includes a group 11 of tensile warps composed of continuous filament yarn and a group 12 of abrasion warps of staple fibre which stand proud of the tensile warps to resist damage from abrasion. The warps 11 may be continuous filaments of polyester, acrylonitrile, nylon or glass whilst the warps 12, which may be at a lower tension than the warps 11, may be of staple fibres of the aforesaid substances or of cotton, rayon, flax, asbestos, or wool. The weft 10 may comprise a single, convolutely wound yarn of continuous filament nylon or alternately spaced convolutions of continuous filament and staple fibre yarn. Alternatively the two types of yarn may be combined into a composite weft. In the second Provisional Specification it is stated that the abrasion warps 12 may be woven so closely as to form loops on the outer surface which may be left uncut, cut, or cut and carded to form an outer felted surface and in the first Provisional Specification a hose is described having a double jacket, the inner jacket comprising the tensile warps and the outer jacket the abrasion warps. Specifications 538,455 [Group XXVIII] and 562,326 are referred to.
