Optimization for the Durability of Crown Needle
The barbs in the leading edge of felting crown needles are worn out far faster than the other barbs, which leads to costly needle replacement. The needle wear results from not only the way of fiber-to-needle friction, but also the number of fiber-to-needle contacts. Assuming that fibers grabbed by all edges are subject to approximately the same mean tension force, thus the uneven wears in different edges are determined mainly by fiber-to-needle contacts. The fiber capture for the barbs in individual edges was modeled according to geometrical probability. Then methods for the reduction of uneven needle wear and increase of needle rotation life were proposed, in terms of web-laid methods, needle mounting, needle manufacturing and loom design, to the manufacturing and processing industries, based on computational simulations using a developed mathematical program.
