As mentioned earlier, elastane draft 4.2 (for yarns of all series) and T400 tension draft 1.3 (for yarns of series V) were so high that frequent filament rupture made the spinning process unstable. Due to too high crimps, many fibers started to protrude from the yarn body which ...
Fiber length affects yarn strength, yarn evenness, and the efficiency of the spinning process. The fineness of the yarn that can be successfully produced from given fibers also is influenced by fiber length. Length Uniformity Length uniformity is the ratio between the mean length and the upper- ...
Carding is the second process of spinning after blow room which converts the feed materials into a uniform strand of fibers called sliver. The short- and medium-term variations of carded slivers are equalized by the doubling action in the draw frame. Moreover, hooked, curled and crimped ...
