EXPLORATORY STUDY OF THE DEVELOPMENT OF NONWOVENCELLULOSIC BLENDS USING HI TECHNOLOGY

摘要

A generous funding from the US Department of Defense through the Admiral Zumwalt, Jr. Program at Texas TechUniversity has resulted in the initiation of a new nonwovens research program. A manufacturing scale "state of the art" H1technology needle punching machinery has been most recently installed at Texas Tech University.The nonwovens laboratory at Texas Tech University is the first and only facility in the US to have the H1 technologyneedleloom. The needle loom is served by a full feeding line from William Tatham Ltd, England. The feed unit consists of ahopper feeder, a two cylinder card and a crosslapper. The card is clothed with aluminum base wire and can handle a varietyof fibers with linear densities ranging from 1.5 - 6 denier. The cross-lapper feeds the H1 technology needle-loom. Theneedle-loom is 1.2 meters wide and is capable of needling up to 1300 strokes/min. This paper will endeavor to report on theprogress of nonwovens research program. The report will discuss about the development of natural fiber nonwovensubstrates. The use of thermal bonding machine to develop multiplayer composite structure will also be discussed briefly.
