Development of a Multidirectional-Stretch Spacer Fabric

摘要

An investigation was conducted to develop a 3-dimensional spacer fabric for use in the air distribution system of the experimental thermalibrium protective clothing system designed by the U. S. Army Natick Laboratories. A multidirectional-stretch spacer fabric known as 'monocoil' made by interlocking coiled monofilaments in a square woven fabric-like configuration, was selected as the candidate system. A variety of materials were studied. Based on analysis of available monofilaments, polyester was chosen as the material to be used in the construction of this 3-dimensional fabric. Numerous monocoil designs were fabricated and tested for air flow, compression, weight, and stretch characteristics. A construction which met specifications was selected for quantity production. Two-hundred linear yards of experimental spacer fabric 42-48 inches wide were manufactured. During development, it was found necessary to apply a protective or restraining cover to control stretch and enable handling of the spacer fabric. Cover materials included high-stretch power net, Jersey-knit Nomex fabric, and neoprene sheeting. (Author)
