Description

  The present invention relates to a moisturizing article. More specifically, the present invention relates to a moisturizing article capable of preventing moisture and keeping moisture on cracked and keratinized skin parts such as hands, heels, knees, and elbows.

  Parts such as hands, heels, knees, and elbows are easily keratinized, and are prone to cracking due to drying. Therefore, conventionally, a moisturizing article has been proposed in which moisture is prevented from diffusing from the portion and the moisture retention is improved. For example, moisturizing socks with a non-breathable cloth attached to the inside of the fabric of the heel part (Patent Document 1), socks for drying prevention with a non-breathable sheet attached to the heel cover part of the sock (Patent Document 2) Elbow and knee pad supporter (patent document 3) using a heat-retaining and moisturizing member formed by laminating a urethane-based synthetic resin film on the fabric inside the part covering the elbow and knee, and silicon functionality on the inner surface of the sock fabric Examples include foot protection socks (Patent Document 4) in which a thin fabric is attached with an adhesive that hardens in a rubber-like manner and includes a base polymer having a base.

  However, synthetic resins such as vinyl chloride and polyethylene that are used as non-breathable members in Patent Documents 1 to 3 have low stretchability, and therefore have low adhesion to the skin, causing a sense of incongruity such as a feeling of stiffness when worn. It was a thing.

  Further, in Patent Document 3, urethane resin is laminated to a non-breathable member, and although the feeling of adhesion to the skin is improved to some extent, it is susceptible to hydrolysis due to moisture in the air, etc. Further, the non-breathable member became hard, and the film was liable to be peeled off or cracked. In Patent Document 4, since a base polymer having a silicon-functional polyorganosiloxane is used as the non-breathable member, the adhesion to the fabric is low, and the non-breathable member is easily peeled off from the fabric by washing or the like. It was easy.

  Therefore, the object of the present invention is excellent in skin protecting effect, extremely high adhesion to the skin when worn, does not cause a sense of incongruity such as a sense of stiffness, has very good usability, and is used over time. An object of the present invention is to provide a moisturizing article that can sufficiently withstand.

  As a result of earnestly examining the above problems, the present inventor, when using a styrene-based elastomer as a non-breathable member, not only has excellent skin protection effects, but also has extremely high adhesion to the skin during use, and usability The present invention has been completed by finding that a moisturizing article can be obtained that is satisfactory and can withstand use over time.

  That is, the present invention relates to a moisturizing article comprising a body covering member and a non-breathable member, wherein the non-breathing member comprising a styrene elastomer sheet is bonded to the body covering member. .

The thickness of the non-breathable member is preferably 0.1 to 2 mm. Moreover, it is preferable that a non-air-permeable member consists of a polystyrene-polyethylene / butylene-polystyrene block copolymer.

  The moisturizing article is preferably a joint supporter, socks or gloves.

  According to the present invention, the inflow of air is blocked and the moisture retention is remarkably enhanced, and it is possible to prevent rough skin and keratinization due to dryness such as bulkiness of hands, heels, elbows, knees, and cracks. In addition, the moisturizing article according to the present invention has high adhesion to the skin, does not cause a sense of incongruity such as a feeling of stiffness, and has very good usability.

  The moisturizing article according to the present invention can bond a non-breathable member to a body covering member by heat fusion, is easy to manufacture, and is less likely to peel or crack even when used over time. Has characteristics.

  The moisturizing article of the present invention is composed of at least a body covering member and a non-breathable member, and the non-breathable member is adhered to the inside of the body covering member that wraps around the rough skin portion and the vicinity thereof. A body covering member is a thing which touches skin and coat | covers a part or all of a body, and has air permeability. For example, normal clothes such as underwear, gloves, socks, and supporters can be used. Further, the non-breathable member is a material that can block the inflow of air. Examples thereof include synthetic resins such as vinyl chloride, polyethylene, and urethane, thermoplastic elastomers, and silicone elastomers.

  As the non-breathable member of the present invention, a styrene elastomer sheet having excellent flexibility and good strength characteristics is used, but other synthetic resins, elastomers and the like can be laminated on the styrene elastomer sheet. is there.

  The thickness of the air-impermeable member is preferably 0.1 to 2 mm, more preferably 0.5 to 1.5 mm. If it is in the said range, there will be no feeling of stiffness and a favorable feeling will be obtained.

The non-breathable member preferably has a hardness (JIA-A) in the range of 15 to 65 from the viewpoints of usability and rough skin improvement, and more preferably, the elongation at break and the strength at break are also broken. It is preferable that the elongation is 750 to 950% and the strength at break is 80 to 200 kg / cm ² .

  The styrene-based elastomer used for the non-breathable member of the present invention is a thermoplastic elastomer, and includes a rubber component having elasticity in the molecule (soft phase) and a molecular constraint component (hard phase) for preventing plastic deformation. It is a polymer material that behaves as a rubber elastic body at room temperature, but undergoes plastic deformation when the temperature rises, because the molecular motion of the soft phase is locally constrained by the hard phase. .

  Specific examples of the styrene elastomer include styrene-butadiene copolymer, styrene-isoprene copolymer, styrene-butadiene block copolymer, styrene-isoprene block copolymer, and styrene-butadiene (block) copolymer. Hydrogenated product, hydrogenated product of styrene-isoprene (block) copolymer, hydrogenated product of styrene-butadiene random copolymer, (block) copolymer of styrene-pentadiene and hydrogenated product thereof, styrene-2, Examples thereof include 3-dimethylbutadiene (block) copolymer and hydrogenated products thereof. These styrenic elastomers are used alone or in combination of two or more.

  Among the styrenic elastomers, the rubber component is preferably composed of a saturated compound (saturated polyolefin block) from the viewpoint of improving rough skin and weather resistance. Particularly preferred is a polystyrene-polyethylene / butylene-polystyrene block copolymer. These copolymers are generally commercially available, and examples thereof include NAGFLEX (manufactured by INOAC Technical Research Laboratories) and lavalon (manufactured by Mitsubishi Chemical Corporation).

  The bonding method between the body covering portion and the non-breathable member is not particularly limited, but it is preferable to bond the body covering portion and the non-breathable member by heat fusion using a hot press plate.

  Hereinafter, embodiments of the present invention will be described in detail with reference to examples.

[Example 1]
