Advanced Technology Applications in Garment Processing

摘要

Several specific technologies have been explored which may form part of the knowledge base necessary for the successful conversion of polymer chips and/or staple fiber directly into garments without spinning, weaving or knitting, cutting and sewing. It is shown that polybutene-1 and polypropylene are soluble in n-butane and carbon dioxide, and nylon-6 dissolves in carbon dioxide. Light weight polypropylene, polybutylene and PBT fibrous webs were formed by melt foam fibrillation. Polypropylene foam fibrillated webs were converted into medium strength yarn. Natural and staple fiber was oriented in low velocity air streams using counter-flow jets and deposited on a screen without loss of orientation.
