2.4.1Ring spinning The ring-spinning process is close to 200 years old. In the last few years a series of developments has taken place, as existing systems have been modified to combine staple yarns with different filaments,conductive yarns, elastomeric materials and high-performance materials such...
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- ...
This spinning process is divided into two main processing routes: regular carding and fine carding, as illustrated in Figure 1. The processing stages encompass cotton carding, sliver drafting, coarse yarn spinning, and fine yarn spinning, among others [17]. Figure 1. Cotton-spinning process flow...

Module averaging does not require a new sampling procedure; it uses the measurements made through the current procedure of obtaining a sample from each side of every bale. With module averaging, all of the individual bale measurements of fiber quality within a module or trailer are averaged, and...

the spinning atom has this electron and this positron ready to pair right before it begins tosuperconduct, and still we can measure it right before it goes into the superconducting state, but once it is in it there is no instrumentation that we are aware of that can determine anything about...
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 ...
