Abstract

PURPOSE:To improve a temperature-keeping property and a moisture-absorbing property for fibrous goods, by a method wherein granular paulownia woods having grain size below a particular dimension are filled between two pieces of cloth, individually or with fiber. CONSTITUTION:For fibrous goods 1, the space between two pieces 2a, 2b of cloth is divided into a number of lattice formed parts with partition members 3, and granular paulownia woods 4 are filled in all of the lattice formed parts or voluntarily in a part of them. A paulownia wood is shaved and cut in the granular form of 0.5mm or below in size and the granular paulownia woods 4 are obtained. This granular paulownia woods 4 are filled in the lattice formed parts between the two pieces 2a, 2b of the cloth. After the granular paulownia woods 4 are filled in the lattice formed parts, the piece 2a is put and is stuck with the partition members 3. As the other way, after the piece 2a is covered, the periphery of two pieces 2a, 2b and proper inside parts of them may be sewed together. Since the granular paulownia woods 4 are divided with every the lattice formed parts, they are not one-sided in the face of the cloth even if the pieces 2a, 2b are large. Since the fibrous goods 1 containing granular paulownia woods 4 are excellent for a temperature-keeping property and a moisture-absorbing property of low level, they can be suitably used for goods, such as a sheet for bedding and clothes for cold weather.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a textile product with improved heat retention and moisture absorption properties using granulated paulownia wood.

[Conventional technology]

IA textile specialty products are generally made from natural fibers such as plant fibers collected from the fruits, stems, or leaves of plants, animal fibers collected from animal hair or cocoons, and synthetic fibers artificially synthesized from various natural raw materials. Both natural fibers and synthetic fibers are used in ways that take advantage of their respective strengths.

Some of these SAW products, such as bedding and winter clothing, are required to have particularly excellent heat retention and low moisture absorption.

Textile products that require such properties can be made by combining woven and non-woven fabrics, mixing grain shells or plastic chips, or using animal feathers and leather in combination. We are trying to compensate for the properties that are lacking in other fibers.

[Problem to be solved by the invention]

As mentioned above, whether it is natural fiber or synthetic fiber, there is no single fiber that satisfies all the characteristics required for textile products. Currently, these are used together.

However, for example, quilts, quilted products, and the like made of natural cotton or synthetic cotton have excellent heat retention properties, but have the problem of being highly hygroscopic.

Also, for example, products made from grain husks are less durable;
Additionally, those using plastic tips have problems such as poor heat retention or poor feel depending on the size of the tip. Also, those that use feathers or leather are expensive.

Therefore, an object of the present invention is to improve the heat retention and moisture absorption properties of textile products by incorporating granular paulownia wood.

[Means to solve the problem]

In order to achieve the purpose of the textile product containing granular paulownia material of the present invention, granular paulownia material with a particle size of Q and 5 mm or less is interposed between fabrics together with a number of vertebrae. Features.

[Effect]

Paulownia wood is the second lightest and softest wood after balsa wood.
Furthermore, paulownia wood has a smaller vessel structure compared to other woods, accounting for only 17.8% of the total, making it difficult to absorb moisture.

In particular, tylose is well developed in the vessels of the spring wood, and there is little communication between them, which has good heat retention and low moisture absorption.

In the present invention, paulownia wood having such characteristics is made of paulownia wood with a particle size of 0.5.
The heat retention and moisture absorption properties of textile products are improved by using granular paulownia wood with a diameter of less than mm, encapsulating the granular paulownia wood between fabrics, and making bedding, cold weather clothing, etc. with the fabric containing the granular paulownia wood. It is.

In the present invention, the particle size of the granulated paulownia wood is set to 0.51'l1m or less because when the paulownia wood is granulated, the vessels are shredded and lose their function as vessels, but the tylose structure This is to maintain the characteristics of paulownia wood, which has good heat retention and low moisture absorption. By pulverizing paulownia wood into particles with a particle size of 0.5 mm or less, the specific surface area of each granular paulownia wood increases, improving thermal conductivity and increasing far-infrared radiation, making it suitable for use in bedding and winter clothing, for example. As a result, heat retention and low moisture absorption are further improved. In addition, when granular paulownia wood is incorporated into fabric alone or together with fibers, it is easy to apply to the fabric and deposit between fabrics, and the thickness of the accumulation is easy to adjust.
Furthermore, there is no problem when bending or folding a textile product containing granular paulownia wood.

In addition, the textile product does not feel hard when used.
