Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a defatted cotton-blended padded cotton used as a padding for a bedding or a kimono and as a padding for a furniture cushion or the like.

[0002]

2. Description of the Related Art Since ancient times, cotton has been used as a material for bedding and kimonos, and is still favored because of its moderate hygroscopicity. On the other hand, in recent years, synthetic fiber cotton has rapidly spread as an alternative to such cotton.

While such synthetic fiber cotton has the advantages of specific volume and light weight, it has been found that it is inferior in hygroscopicity and unsatisfactory as a bedding material, and the goodness of cotton, which is a natural product, is being reexamined. is there.

[0004]

However, the above-mentioned conventional cotton for bedding is obtained by removing seeds from the cotton collected at the place of origin and processing the raw cotton that is packaged and imported. That is, the soil and sand adhering at the place of origin, the mixed leaf stems, etc. are removed with a kneading cotton machine, the fluff is trimmed with a cotton-making machine, and the cotton for middle-introduction is obtained by physical treatment.

[0005] Therefore, the conventional cotton made of cotton contains impurities adhering to the surface of the fluff, fats held by cotton, wax, pectin and the like, and these are used as cotton for cotton. When it is used, it has an appropriate slimy feel and elasticity, but when it is used as a bedding material, it is unsatisfactory in terms of cleanliness, hygroscopicity, moisture release and the like.

[0006] The present invention is a characteristic of cotton is hygroscopic,
It is an object of the present invention to further improve the moisture releasing property and provide a cotton for middle use which is excellent in cleanliness, hygroscopicity and moisture releasing property.

[0007]

Means for Solving the Problems The present inventor has conducted various experimental studies on such cotton for middle use, and as a result, medically defatted cotton which is clean and has excellent hygroscopicity has excellent hygroscopicity / humidity,
The present inventors have found that it can be most suitably used as a cotton pad and completed the present invention.

That is, according to the present invention, the degreased cotton is mixed with 20 to 90% by weight of synthetic fiber cotton such as polyester, acrylic and polypropylene and heat-bonding fiber cotton, and the mixture is subjected to cottonmaking or heat treatment. Was achieved.

If the content of the synthetic fiber cotton or the like is less than 20% by weight, it becomes difficult to maintain the elasticity required for the cotton for filling in for a long time, and if it exceeds 90% by weight, it is degreased. The content of cotton is relatively small, and it is not possible to exert the predetermined effects such as moisture absorption / release.

Further, 10% to 20% of heat-sealing fiber such as ester or polypropylene is added to the mixed cotton, and 120
By heating with hot air of up to 160 ° C., it is possible to manufacture cotton for middle use that does not lose its shape.

Further, for the cotton for the mattresses used for laying, cushions, etc., synthetic fibers to be mixed are thick and denier and hard, and for the kimono and the futon, fine denier and soft feeling. Certain synthetic fibers can be used.

[0012]

[Function] Well degreased cotton is not only clean and harmless to the human body, but also retains high hygroscopicity and high water absorption, and by being mixed with synthetic fiber, it becomes moisture-releasing due to the original capillary phenomenon. It is also excellent in terms of breathability and heat retention.

The conventional cotton lacks the high water absorption and high hygroscopicity, does not work well in the capillary phenomenon, and is inferior in moisture release. In addition, synthetic fibers, which have no hygroscopicity, have excellent elasticity and a large specific volume, and therefore, their drawbacks are compensated for by blending degreased cotton, and each has its advantages and becomes a comfortable cotton for middle use.

[0014]

【Example】

Example 1 40% by weight of degreased cotton and 60% by weight of ester cotton were mixed and put on a cotton maker to produce a cotton strip of about 1 m × 2 m. This cotton for middle use was a product which was excellent in hygroscopicity and moisture release and had an excellent feeling as a cotton for use in kimono and a cotton for use in a kamadan.

Example 2 30% by weight of degreased cotton, 60% by weight of ester cotton, 10% by weight of heat-bonded ester cotton or polypropylene cotton were blended and made into cotton to obtain about 200 g / m ^{2 to 1} kg / m ² . A cotton strip was prepared and further heat treated with hot air at about 150 ° C. for 6 minutes.

[0016] As a result, a hard cotton pad with excellent hygroscopicity and moisture releasing property, which can be comfortably used as a padded cotton for mattress, etc.

The cotton used in the first and second embodiments described above has much higher moisture absorption and desorption properties, which are the original characteristics of cotton, as compared with those obtained by directly using the raw cotton collected from the conventional place of origin. In addition, the original properties of the cotton could be further increased by the synergistic effect of the elasticity of the synthetic fiber and the force of the specific volume.

[0018]

EFFECTS OF THE INVENTION As described above, the cotton for middle use of the present invention is made of degreased cotton as a main material, and synthetic fiber cotton and the like are mixed into the cotton product to obtain strong moisture absorption of the degreased cotton. And the excellent elasticity of synthetic fibers and the synergistic effect of specific volume,
It excels in water absorption and moisture release, softly swells, does not break even during use, has little settling, and can exert the effect of heat-sealing fibers.
