Kuraray, the inventor of Vinylon (Polyviny Alchohol) fiber, has introduced <Claretta-m1>, a new concept yarn technology through its continued research of synthesis of PVA fiber over half a century period.
<Claretta-m1> plays an important assisting roll during the preparation of textile production, but just in the final process before the textile appears on the stage, will disappear completely by being treated in a hot water bath. No trace of existence observed, but it leaves new performance added on finished products .

By dissolving, <Claretta-m1> gives the soft touch to the yarn.
After dissolving by treating with hot water, <Claretta-m1> leaves more space between fiber thus giving the softness, bulk touch, light weight and higher permeability to the yarn completely different from the yarn without it.

Most suited for natural fiber to advance the technology.

![Uniform filament diameter enables to obtain uniformed high quality yarn.](images/make_zu_01.gif)
![Water solubility realizes the fine, stretch and hollow shaped spun yarn in the final process of fabric, but strengthen the yarn during the process of weaving and knitting before it melts.](images/make_zu_02.gif)
![Applied heat during the spinning does not affect the solubility of Claretta-m1 because of its low density polymer.Fine denier will reduce the amount of polymer to be dissolved realizes less burden to the environment.](images/make_zu_03.gif)
