Description

The present invention relates to a method for producing a modified cellulosic fiber material that has been modified so as to enhance the wet exothermic property of the cellulosic fiber material.
Cellulosic fiber materials are excellent in hygroscopicity, but they have the disadvantage of poor wet heat generation and weak heat retention compared to protein fiber materials such as wool, and keep warm when used in underwear and innerwear. Because of its inferior properties, various researches have been made and patent applications have been made with the goal of developing a cellulosic fiber material with excellent wet heat generation.
For example, Patent Document 1 discloses a method of treating a keratin degradation product by an immersion method, a resin processing method, or a chemical bonding method. Patent Document 2 describes a method for improving by introducing an amino group or a carboxyl group, and Patent Document 3 introduces a cationic group into a cellulosic fiber using a quaternary ammonium compound to generate wet heat. A method for imparting sex is disclosed. However, according to the method of Patent Document 3 in which only a cationic group is introduced, there is a property that it has a property of absorbing anions, and stains become conspicuous when washing is repeated.

Warm to 135 ° C. The solution is kept at 135 ° C. for 4 hours and circulated, then drained, washed with water, neutralized with acid, further washed with hot water at 60 ° C. for 5 minutes, washed with water and dried.
A knit fabric was knitted using the rayon yarn obtained by processing in this way, and thermographic surface temperature analysis was performed. That is, the environmental humidity around the test product was changed as follows, and the temperature change on the surface of the fabric was observed.
The material of the example and the material of the comparative example (in the comparative example, the same rayon yarn was washed with hot water at 60 ° C. for 5 minutes, washed with water and dried) and then subjected to an absolute drying treatment at 105 ° C. for 24 hours. Then, the humidity was adjusted at 20 ± 2 ° C. and 65 ± 5% RH (standard state) for 48 hours, and then the test was performed.
Test environment condition 23 ± 2 ℃
The surface temperature of the dough when the humidity was stabilized at 30% RH (about 30 minutes) → 80% RH was observed and measured. As a result, the dough of the example showed a wet exothermic property that was 1.0 to 2.0 ° C. higher than the dough of the comparative example. The processed product of the present invention clearly has a temperature difference of 1 to 2 ° C. compared to the unprocessed product, which confirms that the exothermic sensitivity is large.
Using the yarn of this example, knitting, sewing innerwear, and wearing test, wearing comfort such as heat retention, steaming, and form stability are remarkably superior to the unprocessed product It was confirmed.
Example 2
When the same processing was performed using cotton yarn instead of the rayon yarn in Example 1, a cotton yarn having the same wet heat generation effect as in Example 1 was obtained.
The cellulosic fiber material modified by the method of the present invention has a higher wet calorific value than the unprocessed cellulosic fiber material, and as a result, the wearing comfort such as heat retention and steaminess is improved. In addition, an excellent reforming effect is obtained, for example, that the effect is durable.
Furthermore, the feature of the present invention is that it is possible to provide an excellent wet heat generation effect by using an inexpensive processing agent excellent in safety and environmental compatibility without using harmful agents such as formalin. With the improved economy and excellent economic efficiency, for example, the use of cellulosic fiber materials can be further expanded to fields where there have been many restrictions such as underwear, inner wear, socks, sports equipment, bedding, and lining, It has high practical value and contributes greatly to environmental problems.
