High-grade pure cotton shirt is all with Fine count Yarn line as raw material, but is limited by spinning technique, the most carefully only has
1.79tex, the cotton fiber radical in single thread cross section the most about 14.
For the purified cotton yarns spinning thinner, CN101492843 (Xu Weilin et al. 2008) discloses a kind of embedding
Embedded system positioning spinning method, its main technical point is by two pairs of Seluofle spinning systems, at front roller
Place forms three twisting areas, and with the help of common long filament or water solublity long filament, fiber strip can be by utmost
Ground drawing-off, then twist together with long filament, finally obtain high-count yarn, it was reported that by the yarn that the method obtains
Textile part can reach 1.18tex even 0.98tex, and the yarn produced can be used directly to weave cotton cloth, base to be made
Water-soluble long filament is removed again after cloth.But contain the water-soluble long filament of about 80%, final gained cotton textiles face inside the yarn obtained
Density is little for material, space is big, abnormal the loosest, lose most basic wearability, therefore the most special thin purified cotton yarns
Just it is considered only symbolic meaning and there is no actual application value.

On dyeing bobbin, complete to move back dimension process by hot water in dye vat.But the method for the highest crudefiber crop of yarn count with
Cotton mixed yarn is really effective, because contained water-soluble fibre only has about 20% in the yarn spun, therefore removes water
After dissolubility long filament, the structure change of yarn is little, and the resultant yarn of non-soluble fiber is the strongest.
Preparing the purified cotton yarns being narrower than 0.98tex, water solublity long filament therein or fiber content reach about 80%,
After removing water solublity long filament therein or fiber, the coalition that the pure cotton fiber of remaining about 20% is formed is very
Loose, ultimately result in of both problem:
First, the yarn being wrapped in yarn dyeing tube outer layer is abnormal loose, it is impossible to unwind from yarn dyeing tube by yarn,
It is processed further forming yarn abnormal difficult.
Second, i.e. allow to unwind from yarn dyeing tube, after the water soluble fiber of yarn removal about 80%,
I.e. allowing to resultant yarn, its metric system twist factor only has 210 to 295, much smaller than normal metric system twist factor 350 to 400, because of
The final strength of this yarn is the lowest, does not has any practical value.
