In one embodiment, the present invention relates to a spun yarn comprising 25 to 65% by weight of fibers, 20 to 50% by weight of rayon fibers and 5 to 30% by weight of cotton fibers, separated from the new column.

In the present invention, the fiber separated from the new book means a fiber obtained by refining and washing the raw material to separate and divide the fiber and fragment the fiber. In order to separate the fiber from the Shinseoran, press the Sinseoran leaf with a press to split it to remove moisture, remove non-fiber such as fiber and shell, and then cut the separated fiber into short fibers capable of spinning to produce a yarn. In order to remove non-fibrous materials from fibers, and to make them into fibers, they are necessary to remove impurities. Looking at the chemical composition of the new book is composed of cellulose, holocellulose, lignin, pectin, etc., the content of cellulose and holocellulose is the highest, and the content of lignin is low, but the pectin content is high. Spinning requires effective splitting of the fibers, which requires the removal of pectin. To this end, the shinseoran may be refined with a solution of an alkali compound to enhance the annual deterioration rate. Examples of such alkali compounds include alkali metal hydroxides such as sodium hydroxide, alkaline earth metal hydroxides such as calcium hydroxide, alkali metal carbonates such as sodium carbonate and the like. These alkali compounds may be used alone or in combination with a reaction rate modifier. For example, 4-6 g / L sodium hydroxide and 8-12 g / L sodium carbonate can be mixed and used.

Alkali refining process of the Shinseoran fiber is specifically, after adding the Shinseoran fiber to the refining machine, it is maintained for 10 to 15 minutes in water at 20 ℃, the temperature is raised to 90 ~ 100 ℃ at a rate of 0.8 ~ 1.2 ℃ / min and the alkali component After adding 50 minutes to 80 minutes to refine, finally 20-30 minutes to cold water can proceed to the method. Under these conditions, an optimal new book can be refined. In addition, the concentration of the alkaline solution can be adjusted to be 5 to 6% (o.w.f.) relative to the total weight of the raw material is Sinseo, preferably 5% (o.w.f.). In this content range, it is possible to obtain an appropriate refining age at a minimum cost and to effectively refine pectin and lignin. In addition, the number of refining is increased several times as the refining annual increase rate, it is preferable to carry out two or more times, it is preferable to refine until the clear water is drained at the time of washing.

In addition, the washing process is preferably proceeded to the overflow method using cold water. The thinner column immersed in an alkaline solution is coated with a non-fiber of a slippery, translucent thin film, and can be used after repeatedly removing several times washing with water. In other words, although fiber and non-fiber are separated by alkali in the refiner, but still remain in the refiner, these impurities must be completely separated from the fiber and discharged to the outside of the refiner by washing with water. For this purpose, an overflow method is used, in which water is introduced into the top of the refiner, and the above water has to be repeated several times before drying.

In addition, in the present invention, the fiber may be further subjected to a bleaching process after the alkali refining process. The bleaching process makes the fiber state white and makes the color clear and easy to dye when used as a fabric. This bleaching process is specifically maintained for 10 to 15 minutes in 20 ℃ water, the temperature is raised to 90 ~ 100 ℃ at a rate of 0.8 ~ 1.2 ℃ / min, after adding a bleach (for example, hydrogen peroxide) 40 to 60 minutes You can bleach it while maintaining it, and finally proceed to cold water for 20 to 30 minutes.
