Abstract
Abstract A method of forming a hose construction wherein a peptide surface portion is treated by a nonsolvent material which disrupts the intermoleculer hydrogen bonds between -NH- and -COgroups to soften the surface portion and permit urging of a fibrous second hose element against the softened surface portion to embed the fibrous second portion therein where-upon removal of the treating material permitting reformation of the disrupted intermolecular hydrogen bonds cuases a locked association of the hose elements. The second surface portion is formed of a material substantially inert to the treating material. Also disclosed is a hose construction formed by this method.

Claim 14
Dependent Claim
141 words
A hose construction formed by the steps of: providing a first tubular hose element having a first synthetic linear polyamide surface portion; treating the surface portion to a material disrupting the intermolecular hydrogen bonds of -NH- and -CO- groups of said polyamide surface portion thereby to soften said surface portion; providing a fibrous second hose element having a second surface portion formed of a material substantially inert to said treating material; urging said fibrous second surface portion against said treated softened first surface portion of said tubular hose element to embed the fibrous second surface portion in said softened first surface portion of the tubular hose element; and removing the treating material to cause reformation of the spaced hydrogen bonds of said first surface portion to lock said fibrous second hose element surface portion to said first hose element surface portion.
