The object of 'the present invention is to provide protective outfits and their manufacturing methods, which fit smoothly to patients' symptoms and individual figures, which are easy to wear, which provide excellent wear comfort, and which can be used for medical treatment, sports and foundation garments.
DESCRIPTION OF THE INVENTION
The protective outfits of the present invention consists of a main body comprising elastic material and nonstretchable material or elastic material only and a portion where the elasticity of the elastic material composing the main body is changed by impregnation with a treating agent.
In the manufacturing process of the aforementioned protective outfits, to a specified portion of the elastic material composing the main body which comprises the elastic material and nonstretchable material or elastic material only, the treating agent is applied or bonded in either liquid or solid state, and the elasticity of the specified portion of the elastic material composing the main body is varied by integrating the treating agent with the elastic material.
According to the present invention. impregnating with the treating agent the specified portion of the main body comprising the elastic material can change the elastic characteristics of the specified portion only, applying the proper working force, that is, fixing force, supporting force, and compression force. to the necessary portions according to individual wearer conditions and achieving rational treatment and prevention. Because the outfits themselves integrate the elastic material with a treating agent such as resin, both thickness and weight scarcely vary from those of the elastic material, and they are free from feeling of physical disorder and complicated auxiliary belt, achieving easy application operation. The protective outfits of the present invention do not cause any burden to elderly people and small children and allow them to wear the outfits easily by themselves. In addition, the protective outfits of the present invention is not made up by combining and sewing various materials together as with the conventional protective outfits, but has the treating agents applied or bonded only on the elastic material, resulting in a simple manufacturing process and cost reduction.
Impregnation can be performed with the treating agents at any time before or after the main body is formed from elastic material and nonstretchable material or elastic material only, and the main body can be formed by processing such as cutting and sewing after impregnation is performed with the treating agents for the specified portion of the elastic material, or impregnation with the treating agent can be performed for the specified portion of the elastic material composing the main body after the main body is formed from the elastic material and nonstretchable material or elastic material only.
The main body consisting of elastic material and nonstretchable material is especially effective for the protective outfits requiring a fixing force, for example, a rib-fracture fixation bandage and protective outfit for lumbago. More specifically, in the rib-fracture fixation bandage, nonstretchable material is used for the side which makes contact with the affected portion, and impregnation is carried out for the elastic material on the not-affected side. For the low back pain belt, nonstretchable material is used for the abdomen and elastic material for other portions, to which impregnation is carried out as required.
The main body which consists of only elastic material is effective primarily for the outfits which fix, support, and compress joints and foundation garments which smooth and trim the body figure. The outfits for joints include those for hand joints, elbow joints, knee joints, and feet joints, and those for foundation garments include girdles, and abdominal and back supports after pregnancy. These outfits provide easiness to wear and good wear comfort by composing the whole outfits with elastic material, and, then, performing the impregnation treatment of the present invention according to human muscles will produce effective outfits.
All that is required for the elastic material used for the present invention is material with sufficient stretchability that allows the material to fit to the surface contour of the human body, and it is the material with an elongation ratio of more than 20%, preferably 50 -150%. The form of the main body to be formed from the elastic material includes a flat one and a tubular-formed cylindrical one. The flat form can be formed with woven.
knitted, and nonwoven fabrics or composite material, while the cylindrical form can be formed with knitted fabrics. For the woven fabric, stretchable yarns such as rubber, polyurethane, hard-twisted, crimped, and conjugated yarns, preferably rubber and polyurethane yarns, are used for, at least, either warp or weft. For the knitted fabrics, natural, semi-synthetic, and synthetic yarns knitted in warp or weft, or yarns into which elastic yarns (preferably rubber and polyurethane yarns) are knitted can be used. For nonwoven fabrics, nonwoven fabrics using elastic fibers produced by. in particular, the~Spunbond. Spun-Lace, and Melt-Blow methods are preferable. For composite material.
double structure in which elastomeric material is applied or stuck to the stretchable fabric or triple,structure in which elastic fabric, elastomer material, and elastic fabric are stuck together can be used, wherein polyurethane, polychloroprene rubber, polYbutadiene rubber, natural rubber. polyvinyl chloride foams. or nonwoven fabric comprising fibers of urethane. polYamide, etc. are preferable the elastomeric material. It is also possible to use two or more types of elastic materials.
Examples of nonstretchable material include cotton, polyester. polyamide. polyacrylonitrile fabrics, nonwoven fabrics or composite materials.
The treating agent used in the present invention must enter the elastic material fibers or structure to be integral with the elastic materials and vary the elastic properties (elongation ratio, modulus), feeling (flexibility, rigidity, friction coefficient), and warmth-retaining characteristics, and the example includes rubber and plastic materials. They are provided in either liquid or solid form, and the liquid form is obtained by dissolving rubber or plastics in an organic solvent, and emulsifying or suspending rubber or plastics. The solid form is obtained by bringing rubber or plastics into films, sheets, bars and powders, or into woven, knitted, and nonwoven fabrics by working.
The rubber material for the treating agent falls into two broad categories: natural and synthetic. Examples of synthetic rubber include polYisoprene, polYbutadiene rubber.
butadiene-styrene copolymer. butadiene-acrylonitrile copolyer, polychloroprene rubber, isobutene-isoprene copolymer.
polyester isocyanate rubber.' polYether isocYa~ate rubber.
chlorosulfonated -Polyethylene, ethylene-propylene copolymer, ethylene-propylene-diene trimer, polydimethylsiloxane, polyacrylic ester, styrene-isoprene-styrene copolymer.
The plastic material for the treating agent falls into two broad categories: thermosetting and thermoplastic resin.
Examples of thermosetting plastics include formaldehyde resin and bridge formation resin. Examples of formaldehyde resin include phenol resin, urea resin, and melamine resin and those of bridge formation resin include unsaturated polyester, epoxy resin, diallyl phthalate resin, silicone, and polyurethane. Examples of thermoplastic resins include hydrocarboncarbide plastics, polar vinyl plastics, linear-structure plastics, and cellulose plastics. Hydroparbon-carbide plastics include polyethylene, polypropylene, polymethylpentene. polybutene. t- polybutadiene, poly-styrene, styrene-butadiene, polar vinyl plastics include polyvinyl-chloride, polyvinyl-acetate, polymethyl-methacrylate, polYvinylidene chloride, polytetrafluoro-ethylene, ethylene-vinyl-acetate copolymer, styrene-acrylate copolymer, ionomer resin, acrylate-styrene-acrylonitrile copolymer, linear structure plastics include polyacetal.
polycarbonate, polyphenyleneoxide, polyethylene terephtha-late, polybutyleneterephthalate, polyacrylate, polysulfone, polyethersulfone polyphenylenesulfite, and cellulose plastics include cellulose acetate, cellulose acetate butyrate."Celluloid"* and "Cellophane"*.
The treating agent used in the present invention can be grouped in the following four categories in terms of the functions required.
(1) Treating agent that increases fixing and supporting forces:
The supporting force is increased by eliminating flexibility and elasticity of the elastic material and the fixing force is increased by providing resistance to bending as well as eliminating flexibility and stretchability of the elastic material.
Examples of these agents include epoxy resin.
unsaturated polyester resin, thermosetting urethane resin.
and diallyl phthalate resin for thermosetting resins.
polystyrene, polypropylene, trans-polyisoprene, polystyrene, polyvinyl chloride, polyvinyl acetate, polymethyl-* Trademark _g-methacrylate, polYvinYlidene chloride, ethylene-vinyl acetate copolymer, acrylonitrile-butadiene-styrene copolymer, polyester resin, polYamide, thermoplastic polyurethane resin, and ionomer resin for thermoplastic plastics.
Particularly preferable are epoxy resin, unsaturated polyester resin, thermosetting or thermoplastic urethane resin and ionomer resin.
To this treating agent, a plastic resin with comparatively high crystallinity or a high degree of crosslinking applies. The supporting force can be easily increased by applying a smaller amount of treating agent to the elastic material, while the fixing force can be increased by increasing the amount of the.treating agent.
(2) Treating agent that increases compression forces:
This intends to increase the modulus of the elastic material, that is, to provide a function to recover the original form when the material is extended.
For this purpose, in general, a treating agent called elastomer possessing rubber elasticity can be used, and the example includes natural rubber. polyurethane elastomer, styrene-butadiene rubber. polYChloroprene rubber, butadiene-acrylonitrile rubber, polyisobutylene rubber.
styrene-isoprene-styrene copolymer, silicone rubber, isobutene-isoprene rubber, butadiene rubber, and polytetrafluoroethylene rubber, and more preferably. natural rubber, polyurethane elastomer, styrene-butadiene rubber, polychloroprene rubber, polystyrene-isoprene-styrene copolymer The compresvsion force can be varied by varying the amount of treating agent and selecting the treating agent with high modulus.
(3) Treating agent that controls elongation ratio:
The treating agent does not affect flexibility at all and only restricts elongation. There is hardly any change in back stretch.
This treating agent is an elastomer, and can be formed by adding a plasticizer to rubber or plastics with small rubber elasticity. such as polyvinyl chloride, polyvinyl acetate, polyvinyl alcohol, ethylene-vinylacetate copolymer, and polyacrylic acid ester, and most preferably, polyvinyl chloride, polyvinyl acetate, and polyacrylic acid ester. In particular. to have better flexibility, it is recommended to select a treating agent with low hardness or to decrease hardness by adding a plasticizer.
(4) Treating agent that increases warmth-retaining property:
The treating agent forms structure to store the air by bonding to the elastic material and foaming, and can use foaming compounds with the natural rubber, thermoplastic polyurethane resin, and polyvinyl chloride used as a base, and more preferably, those using thermoplastic polyurethane resin and polyvinyl chloride.
In the protective outfits constructed as above, the main body without any impregnation treatment possesses the stretchable properties which the elastic material originally possesses, but the portion which underwent the impregnation treatment possesses stretchable properties different from those of the elastic material. Therefore, the fixing force. supporting force. compression force, or warmth-retaining force at the portion applied to the human body when the outfit is worn can be increased as required at the portions which were subJected to impregnation treatment, producing a desired treatment effect in medical use, a desired prevention effect in sports use, and a desired figure shaping effect in foundation garments. The weight of the outfits can be as li8ht as that determined by the main body being almost made up of elastic material only.
The protective outfits of the present invention can be manufactured in a simple process consisting of only impregnation treatment of the elastic material with the treating agent.

According to the present invention. impregnating with the treating agent the specified portion of the main body comprising the elastic material can change the elastic characteristics of the specified portion only, applying the proper working force, that is, fixing force, supporting force, and compression force. to the necessary portions according to individual wearer conditions and achieving rational treatment and prevention. Because the outfits themselves integrate the elastic material with a treating agent such as resin, both thickness and weight scarcely vary from those of the elastic material, and they are free from feeling of physical disorder and complicated auxiliary belt, achieving easy application operation. The protective outfits of the present invention do not cause any burden to elderly people and small children and allow them to wear the outfits easily by themselves. In addition, the protective outfits of the present invention is not made up by combining and sewing various materials together as with the conventional protective outfits, but has the treating agents applied or bonded only on the elastic material, resulting in a simple manufacturing process and cost reduction.
Impregnation can be performed with the treating agents at any time before or after the main body is formed from elastic material and nonstretchable material or elastic material only, and the main body can be formed by processing such as cutting and sewing after impregnation is performed with the treating agents for the specified portion of the elastic material, or impregnation with the treating agent can be performed for the specified portion of the elastic material composing the main body after the main body is formed from the elastic material and nonstretchable material or elastic material only.
The main body consisting of elastic material and nonstretchable material is especially effective for the protective outfits requiring a fixing force, for example, a rib-fracture fixation bandage and protective outfit for lumbago. More specifically, in the rib-fracture fixation bandage, nonstretchable material is used for the side which makes contact with the affected portion, and impregnation is carried out for the elastic material on the not-affected side. For the low back pain belt, nonstretchable material is used for the abdomen and elastic material for other portions, to which impregnation is carried out as required.

The outfits for joints include those for hand joints, elbow joints, knee joints, and feet joints, and those for foundation garments include girdles, and abdominal and back supports after pregnancy. These outfits provide easiness to wear and good wear comfort by composing the whole outfits with elastic material, and, then, performing the impregnation treatment of the present invention according to human muscles will produce effective outfits.
All that is required for the elastic material used for the present invention is material with sufficient stretchability that allows the material to fit to the surface contour of the human body, and it is the material with an elongation ratio of more than 20%, preferably 50 -150%. The form of the main body to be formed from the elastic material includes a flat one and a tubular-formed cylindrical one. The flat form can be formed with woven.
knitted, and nonwoven fabrics or composite material, while the cylindrical form can be formed with knitted fabrics. For the woven fabric, stretchable yarns such as rubber, polyurethane, hard-twisted, crimped, and conjugated yarns, preferably rubber and polyurethane yarns, are used for, at least, either warp or weft. For the knitted fabrics, natural, semi-synthetic, and synthetic yarns knitted in warp or weft, or yarns into which elastic yarns (preferably rubber and polyurethane yarns) are knitted can be used. For nonwoven fabrics, nonwoven fabrics using elastic fibers produced by. in particular, the~Spunbond. Spun-Lace, and Melt-Blow methods are preferable. For composite material.
double structure in which elastomeric material is applied or stuck to the stretchable fabric or triple,structure in which elastic fabric, elastomer material, and elastic fabric are stuck together can be used, wherein polyurethane, polychloroprene rubber, polYbutadiene rubber, natural rubber. polyvinyl chloride foams. or nonwoven fabric comprising fibers of urethane. polYamide, etc. are preferable the elastomeric material. It is also possible to use two or more types of elastic materials.
Examples of nonstretchable material include cotton, polyester. polyamide. polyacrylonitrile fabrics, nonwoven fabrics or composite materials.
The treating agent used in the present invention must enter the elastic material fibers or structure to be integral with the elastic materials and vary the elastic properties (elongation ratio, modulus), feeling (flexibility, rigidity, friction coefficient), and warmth-retaining characteristics, and the example includes rubber and plastic materials. They are provided in either liquid or solid form, and the liquid form is obtained by dissolving rubber or plastics in an organic solvent, and emulsifying or suspending rubber or plastics. The solid form is obtained by bringing rubber or plastics into films, sheets, bars and powders, or into woven, knitted, and nonwoven fabrics by working.
The rubber material for the treating agent falls into two broad categories: natural and synthetic. Examples of synthetic rubber include polYisoprene, polYbutadiene rubber.
butadiene-styrene copolymer. butadiene-acrylonitrile copolyer, polychloroprene rubber, isobutene-isoprene copolymer.
polyester isocyanate rubber.' polYether isocYa~ate rubber.
chlorosulfonated -Polyethylene, ethylene-propylene copolymer, ethylene-propylene-diene trimer, polydimethylsiloxane, polyacrylic ester, styrene-isoprene-styrene copolymer.
The plastic material for the treating agent falls into two broad categories: thermosetting and thermoplastic resin.
Examples of thermosetting plastics include formaldehyde resin and bridge formation resin. Examples of formaldehyde resin include phenol resin, urea resin, and melamine resin and those of bridge formation resin include unsaturated polyester, epoxy resin, diallyl phthalate resin, silicone, and polyurethane. Examples of thermoplastic resins include hydrocarboncarbide plastics, polar vinyl plastics, linear-structure plastics, and cellulose plastics. Hydroparbon-carbide plastics include polyethylene, polypropylene, polymethylpentene. polybutene. t- polybutadiene, poly-styrene, styrene-butadiene, polar vinyl plastics include polyvinyl-chloride, polyvinyl-acetate, polymethyl-methacrylate, polYvinylidene chloride, polytetrafluoro-ethylene, ethylene-vinyl-acetate copolymer, styrene-acrylate copolymer, ionomer resin, acrylate-styrene-acrylonitrile copolymer, linear structure plastics include polyacetal.
polycarbonate, polyphenyleneoxide, polyethylene terephtha-late, polybutyleneterephthalate, polyacrylate, polysulfone, polyethersulfone polyphenylenesulfite, and cellulose plastics include cellulose acetate, cellulose acetate butyrate."Celluloid"* and "Cellophane"*.
The treating agent used in the present invention can be grouped in the following four categories in terms of the functions required.
(1) Treating agent that increases fixing and supporting forces:
The supporting force is increased by eliminating flexibility and elasticity of the elastic material and the fixing force is increased by providing resistance to bending as well as eliminating flexibility and stretchability of the elastic material.
Examples of these agents include epoxy resin.
unsaturated polyester resin, thermosetting urethane resin.
and diallyl phthalate resin for thermosetting resins.
polystyrene, polypropylene, trans-polyisoprene, polystyrene, polyvinyl chloride, polyvinyl acetate, polymethyl-* Trademark _g-methacrylate, polYvinYlidene chloride, ethylene-vinyl acetate copolymer, acrylonitrile-butadiene-styrene copolymer, polyester resin, polYamide, thermoplastic polyurethane resin, and ionomer resin for thermoplastic plastics.
Particularly preferable are epoxy resin, unsaturated polyester resin, thermosetting or thermoplastic urethane resin and ionomer resin.
To this treating agent, a plastic resin with comparatively high crystallinity or a high degree of crosslinking applies. The supporting force can be easily increased by applying a smaller amount of treating agent to the elastic material, while the fixing force can be increased by increasing the amount of the.treating agent.
(2) Treating agent that increases compression forces:
This intends to increase the modulus of the elastic material, that is, to provide a function to recover the original form when the material is extended.
For this purpose, in general, a treating agent called elastomer possessing rubber elasticity can be used, and the example includes natural rubber. polyurethane elastomer, styrene-butadiene rubber. polYChloroprene rubber, butadiene-acrylonitrile rubber, polyisobutylene rubber.
styrene-isoprene-styrene copolymer, silicone rubber, isobutene-isoprene rubber, butadiene rubber, and polytetrafluoroethylene rubber, and more preferably. natural rubber, polyurethane elastomer, styrene-butadiene rubber, polychloroprene rubber, polystyrene-isoprene-styrene copolymer The compresvsion force can be varied by varying the amount of treating agent and selecting the treating agent with high modulus.
(3) Treating agent that controls elongation ratio:
The treating agent does not affect flexibility at all and only restricts elongation. There is hardly any change in back stretch.
This treating agent is an elastomer, and can be formed by adding a plasticizer to rubber or plastics with small rubber elasticity. such as polyvinyl chloride, polyvinyl acetate, polyvinyl alcohol, ethylene-vinylacetate copolymer, and polyacrylic acid ester, and most preferably, polyvinyl chloride, polyvinyl acetate, and polyacrylic acid ester. In particular. to have better flexibility, it is recommended to select a treating agent with low hardness or to decrease hardness by adding a plasticizer.
(4) Treating agent that increases warmth-retaining property:
The treating agent forms structure to store the air by bonding to the elastic material and foaming, and can use foaming compounds with the natural rubber, thermoplastic polyurethane resin, and polyvinyl chloride used as a base, and more preferably, those using thermoplastic polyurethane resin and polyvinyl chloride.
In the protective outfits constructed as above, the main body without any impregnation treatment possesses the stretchable properties which the elastic material originally possesses, but the portion which underwent the impregnation treatment possesses stretchable properties different from those of the elastic material. Therefore, the fixing force. supporting force. compression force, or warmth-retaining force at the portion applied to the human body when the outfit is worn can be increased as required at the portions which were subJected to impregnation treatment, producing a desired treatment effect in medical use, a desired prevention effect in sports use, and a desired figure shaping effect in foundation garments. The weight of the outfits can be as li8ht as that determined by the main body being almost made up of elastic material only.
The protective outfits of the present invention can be manufactured in a simple process consisting of only impregnation treatment of the elastic material with the treating agent.
