Abstract
Abstract Methods are provided for producing protective and useful wearing apparel, such as work gloves, work boots and aprons, and wearing apparel so produced by such methods. The methods include joining a non-woven fibrous web, such as needled felt to a knitted web, such as a knitted jersey, and utilizing a needled staple fiber preferably from the non-woven web to join the two webs together into a formed laminate. The joining procedure is such that the finished laminate includes the needled staple fiber extending from one surface of the web to form a base surface for a subsequent application of an elastomeric coating. The resulting coated surface is textured to provide a gripping surface, for example, for use in gloves to handle smooth surfaced items with sharp edges, such as glass. The remaining exposed non-woven fibrous web surface forms a soft protective internal surface for the weaving apparel such as gloves or boots. The outer coating may be liquid impervious, or it may be permeable in order to provide a fabric laminate which is "breathable".
