Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to natural fibers, regenerated fibers,
Good cooling sensation to the wearer at the time of wearing of fibers in textile products such as yarns, woven fabrics, knitted fabrics, non-woven fabrics or garments composed of these, alone or in a mixture of synthetic / semi-synthetic fibers. The present invention relates to a novel finishing composition for fibers and a finishing method for imparting an effect.

[0002]

2. Description of the Related Art At the time of wearing clothing and the like,
Finishing agents for imparting a good cooling effect are known, for example, as cooling agents. A conventional cool sensation processing agent obtains a cool sensation by processing an inorganic compound represented by colloidal silica on a fiber. In particular,
By attaching an inorganic powder such as colloidal silica to the fiber using a polymer binder, a process that gives the skin a "smooth feeling" when worn, and by treating the fiber with alkali such as caustic soda, Remove the oil content of the fiber and use a finishing method without using a finishing agent that gives a slimy feeling, or process a moisture-permeable resin such as a polypeptide on the fiber to improve perspiration. Examples of such processing include improvement.

[0003] Also, a method of obtaining a cool feeling by devising a knitting method or a weaving method in the production of a textile product is known. Specifically, a method of using a strongly twisted yarn or hemp as a material, A method using a water-absorbing acrylic fiber or the like may be used.

[0004]

However, any of the post-processing using a cooling sensation processing agent does not have a sufficient effect of giving a cooling sensation, and furthermore, a processing of adhering an inorganic powder such as colloidal silica onto the fiber. Also, in the processing of treating the fiber with alkali such as caustic soda, the smoothness and strength of the fiber are impaired, which causes pinholes and the like due to the sewing machine needle at the time of sewing, and lowers the productivity at the time of sewing.
And quality degradation occurs.

[0005] In addition, when devising a material or organization, the material or organization to be used is limited, and it is not possible to adapt to a wide range of commercialization that meets the tastes of consumers.

[0006]

SUMMARY OF THE INVENTION The present invention provides a fiber finish composition containing a sugar alcohol as an essential component.

This can respond to a wide range of commercializations regardless of the material and organization, and does not adversely affect post-processing such as sewing.

[0007] When sugar alcohols such as xylitol and sorbitol used in the present invention dissolve in water, they lose heat of dissolution, and the temperature of their aqueous solutions decreases. The degree of the temperature lowering effect is indicated by the heat of dissolution of the sugar alcohol in water. For example, the heat of dissolution of xylitol is -38 cal /
g, mannitol -29 cal / g, sorbitol -2
7 cal / g, sucrose is -4 cal / g.
