Research of influence of blended yarn structure including stainless steel fibers on its properties

Abstract

Analysis of changes in the electrical resistance of different blended of yarns containing stainless steel fibers Bekinox® before and after plying very important for develop antistatic textile materials. Hypothesis was suggested that the plying of two strands leads to yarn conductivity increasing because of rise of the contacts number between stainless steel fibers on their surfaces. Producing of ring-spun 20 tex yarns and 2-ply yarns of linear density 20 tex × 2 were investigated. It is found that that the addition of 10 % stainless fibers into the yarn reduces its electrical resistance in 105 – 106 times. Experimental results show that after plying the yarn conductivity increases. However, this degree of this effect depends on the type of non-conductive fiber (cotton or polyester). Based on the yarn structure simulation it is proven that plying of two strands leads to yarn conductivity increasing because of rise of the contacts number between stainless steel fibers on their surfaces.
