2. Description of the Related Art Negative ions are negatively charged particles (small ions) of particles (small ions) floating in the air by gathering about 10 to 100 molecules. Irradiation of energy such as radiation, ultraviolet rays, and heat rays (far infrared rays) to electrically neutral molecules causes negative electrons to be peeled off, and the peeled negative electrons are captured by other molecules. Also, when fine water droplets split in the air, the water droplets are charged to the anode,
Ambient air is also generated by the ionization phenomenon (Lenard phenomenon) of air charged on the cathode. Negative ions are used to treat stiff shoulders, neuralgia, rheumatism, chills, back pain, roughness, bruising, sprains, frost and fever, recovery from fatigue, sleep,
It is known to exert an excellent effect on improving the constitution (called a negative ion effect).

[0003] Therefore, health materials have been proposed in which fine powder of natural ore which emits α-rays, β-rays and γ-rays (radiation) is applied to textiles such as clothes and bedding which directly or indirectly touch the body, such as bedding. (For example, Japanese Patent Publication No. 62-32948,
JP-A-3-185109). This health material is obtained by bonding a fine powder of a natural radioactive rare element mineral to a sheet together with a resin, or kneading the fine powder into a thread.The radiation emitted from the natural radioactive rare element mineral produces a negative ion effect. It is something to show. In addition, yarns kneaded with fine powder of tourmaline (electric rock), barley rock, and Iio rock, and fiber materials such as cloth coated with the fine powder are known. This type of fiber material exerts a negative ion effect by far infrared rays emitted from tourmaline ore or the like.

[0004] On the other hand, silk has a better touch than cotton, wool, and synthetic fibers, has moisturizing properties, water absorption, drying effects, flexibility, and the like, and does not damage the skin (referred to as silk properties). ). For this reason, products in which a portion directly in contact with the skin is covered with a fiber material woven with silk are used. However, since silk is expensive, conventional methods have been to apply silk characteristics to the surface of cotton yarn or synthetic fiber yarn by a certain method and then make it into a woven fabric, or to add silk characteristics to the surface of a fabric woven with cotton yarn or synthetic fiber yarn. Has been done since.
In this method, silk fibroin is hydrolyzed to produce an aqueous solution of a low-molecular-weight polypeptide (referred to as "hydrolyzed silk solution"), and a fiber material such as cloth or yarn is placed in a bath filled with the aqueous solution. After dipping, squeezing and drying, a certain amount of low molecular weight polypeptide made of silk is adhered to the fiber material. The low molecular weight polypeptide made of silk attached to the surface of a thread or a cloth softens the contact between the skin and a synthetic fiber thread, a cotton thread, or a cloth or the like produced from these, and prevents the skin from becoming rough or dry.

[0005]

However, the effects of radiation-based health materials on human genes are not clear, and there is a demand for the use of health materials, especially for young people, to avoid using them as much as possible. In addition, fiber materials that use far-infrared rays emit a small amount of far-infrared rays, and in order to obtain a certain negative ion effect, the amount of adhesion must be increased. There is a problem that the texture of the used fiber material or fiber product is deteriorated.

[0006] On the other hand, a product obtained by simply attaching a low-molecular-weight polypeptide made of silk to the surface of a yarn or a cloth has a drawback that it is dropped off by washing several times. Various means for improving the washing resistance have been tried, but no means that is economical and has sufficient washing resistance has been found yet.

2. lgLoss 0.61 Taking the quartz schist with the above composition as an example, the amount of negative ions generated between this and the tourmaline was compared and examined. Water was circulated through a stainless steel column filled with quartz schist and fine powder of tourmaline, and activated water was taken into a beaker. The water was taken out and absorbed by Japanese paper, and was fixed to a measuring suction port of a KST-900 ion tester manufactured by Kobe Denki Co., Ltd. The amount of generated negative ions was measured while sucking air.

FIG. 1 is a graph showing the amount of negative ions generated from quartz schist, and FIG. 2 is a graph showing the amount of negative ions generated from tourmaline. In both figures, the vertical axis is the number of ions / cc, and the horizontal axis is the measurement time (number of times). In the case of quartz schist, the upper limit of the measurement exceeds 50,000, and it is estimated that the number is about 70,000 to 80,000. On the other hand, in the case of tourmaline, the maximum is 10,000, and the average is 5,000. Therefore, it can be seen that quartz schist has a negative ion generating ability at least about 7 to 8 times that of tourmaline and exhibits a large negative ion effect with a small amount of adhesion.

FIG. 3 shows the far-infrared radiation energy of the quartz schist (solid line a) and the synthetic zeolite (broken line c) at 200 ° C., and the far-infrared radiation of the quartz schist (dashed line b) at 40 ° C. It shows the amount of energy. FIG. 4 shows the far-infrared radiant energy rates of the quartz schist (solid line d) and the synthetic zeolite (dashed line e) at 60 ° C.

Example 1 The above-mentioned quartz schist was pulverized to a particle size of 6 μm or less, and the mixed powder obtained by adding the above-mentioned synthetic zeolite pulverized to a particle size of 6 μm or less was dissolved in ethyl acetate. It is mixed with an acrylic resin and the viscosity is adjusted to produce a resin composition for coating. The coating composition was applied to a polyester fiber fabric using a floating knife coater and dried at 180 ° C. for 1 minute. When the underwear was manufactured from this woven fabric, the texture was good and a negative ion effect was exhibited.

Example 2 Fine particles of quartz schist and synthetic zeolite having a particle size of 6 microns were mixed with a resin in the following mixing ratio to produce a dispersant for fiber impregnation, and the dispersant was impregnated into a fabric by a padding method. After drying.

Example 3 Quartz schist is finely pulverized to a particle size of 6 μm or less, dispersed in water, heated and maintained at about 100 ° C. Adjust the suspension. This suspension is electrolyzed to elute mineral components into ions. The eluted hydrates, such as metal ions, undergo hydrolysis to become molecules with a high degree of condensation, and these molecules aggregate together with the finely pulverized particles of quartz schist to form colloidal particles. This is filtered and mixed with glycol to prevent coagulation and sedimentation of the components to obtain a dispersion-stabilized quartz schist gel.

On the other hand, the fibroin of silk is hydrolyzed to a low molecular weight to obtain an aqueous solution of a low molecular weight polypeptide made of silk (hydrolyzed silk solution). The composition of this hydrolyzed silk solution is as follows: hydrolyzed fibroin (low molecular weight polypeptide made of silk) 4 to 6%, decomposer and neutralizer (inorganic) 1 to 3%, preservative (methyl and propylparaben)
0.2%, preservative (ethanol) 1.0%, balance water.

Fine powders of quartz schist and synthetic zeolite mixed in a ratio of 1: 1 and a hydrolyzed silk solution were added to the following low-temperature drying type aqueous binder to prepare a resin composition for coating. The aqueous binder is an emulsion that cures at or below the decomposition temperature (120 ° C.) of the low molecular weight polypeptide made of silk, and its main component is an acrylate copolymer. The physical properties of the acrylate copolymer were as follows: weight average molecular weight 250,000, solid content 42%, pH 5
7. Viscosity 500 mPa · S or more, Tg = −45 ° C. An aqueous solution containing a polyether-based polyurethane resin and a polyester resin was added as an auxiliary agent. The auxiliaries are
It provides uniformity and water absorption when the low molecular weight polypeptide made of silk contained in the hydrolyzed silk solution and the acrylate copolymer are combined.

The coating resin composition having the above composition was applied to a polyester fiber fabric and cured at 120 ° C. for 1 minute. When the washing resistance of this fabric was tested, 50
Even after washing up to 100 times, the properties of the silk such as the initial moisturizing property and the touch were retained. When underwear was manufactured using this cloth, the feeling and feel were good and the negative ion effect was exhibited. In addition, antibacterial agents such as chitin chitosan and hinokitiol can be mixed into the above coating composition.

This aqueous binder is a water-dispersed solution that cures at 120 ° C. or lower, and its main component is an ester polymer. Since the ester polymer has a high affinity for cotton, it was impregnated into a cotton fabric product and dried at 120 ° C. for 1 minute. It feels good and feels good and has a negative ion effect. When the washing resistance of this product was tested,
Even after being washed 00 times, the original moisturizing property, touch and the like were retained.
