DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an artificial leather glove made of a stretchable leather-like material having excellent leather, heat-retaining and protective properties and having a leather-like appearance. is there.

<Conventional technology> Conventionally, a suede-like artificial leather in which a substrate obtained by containing an elastic polymer such as polyurethane elastomer in a fiber-entangled nonwoven fabric is finished on the surface fiber raised suede surface or an elastic polymer such as polyurethane elastomer on one surface of the substrate. It has already been practiced to sew an artificial leather with silver, which has been finished by applying the above-mentioned coating layer, to an artificial leather glove by sewing. It is also proposed in Japanese Patent Laid-Open No. 60-7876 to process artificial leather made of a specific entangled nonwoven fabric into golf means.

<Problems to be Solved by the Invention> Although conventional artificial leather gloves have flexibility, they cannot be obtained as gloves having good fitting properties because of their low elasticity. If gloves with a smaller size are used to obtain the fit property, the shape will change. There were drawbacks such as a feeling of tight binding and discomfort.

The present invention is to provide an artificial leather glove having large stretchability, excellent fittability, and improved wearability. Further, it is an object of the present invention to provide an artificial leather glove which has a small morphological change such as wrinkles and bulges in the finger joint portion even after long-term use and is excellent in heat retention.

<Means for Solving the Problems> The present invention is a three-dimensional entangled nonwoven fabric comprising 50 to 85% by weight of non-elastic fineness fibers or / and bundled fibers thereof and 50 to 15% by weight of elastic fibers. , One surface of the three-dimensional entangled nonwoven fabric is a leather-like material which is a suede-like surface made of fiber naps or a silver surface made of a polymer film mainly composed of an elastic polymer,
The apparent density of the leather-like material is 0.25 to 0.75 g / cm ³ , the elongation percentage is at least 25% without causing structural failure in elongation in at least one direction, and elasticity 30 seconds after releasing the elongation state. An artificial leather glove made of stretchable leather having a recovery rate of at least 80%.

The stretchable leather-like material constituting the artificial leather glove of the present invention is a multi-component fiber obtained by spinning at least two polymers having different solubilities (the cross-sectional shape of the fiber is one type of heavy fiber). A fiber having a sea-island structure or a multi-core core-sheath structure or a fiber having an alternating junction type split structure, in which a polymer is used as a dispersion medium component and another polymer is a dispersion component, and one type of multi-component fiber is at least Fibers composed of two types of non-elastic polymers, for example, components used as non-elastic fineness fibers include polyesters containing aromatic rings such as polyethylene terephthalate and polybutylene terephthalate, nylon-6, nylon-6.6, nylon- A polymer selected from polyamides such as 6.10 and the like, polyolefins such as polyethylene and polypropylene, acrylonitrile and the like, in which the removed fiber component is high fluidity polyethylene, Polystyrene or styrene copolymer, ethylene copolymer, (a multi-component fibers I) fibers consisting of selected polymers from polyvinyl chloride. Another type of multi-component fiber is a fiber composed of an elastic polymer and an inelastic polymer, for example, a component used as an elastic fiber is polyester diol, polyether diol, polyester ether diol, polylactone diol, polycarbonate. A polyurethane elastomer obtained by reacting at least one polymer diol selected from diols, an organic polyisocyanate, and a low molecular weight compound having two active hydrogen atoms. A polyester elastomer obtained by subjecting at least one of the above polymer diols, an aromatic dicarboxylic acid or an ester thereof, and a low-molecular diol to condensation reaction, if necessary. It is a polymer selected from acrylonitrile-butadiene copolymer and the like, and the removal fiber component is a non-elastic polymer selected from high fluidity polyethylene, polystyrene or styrene copolymer, ethylene copolymer, polyvinyl chloride, etc. Fiber (multi-component fiber II)
In the final entangled non-woven fabric, the non-elastic fineness fiber or / and its bundled fiber is 50 to 85% by weight, and 50% as the elastic fiber.
Blend 15 parts by weight of multicomponent fibers I and II. Since the product with high elasticity can be obtained by increasing the blended amount of the multi-component fiber II, the blended amount is determined according to the product design. Further, in the case of a leather-like material to which silver cotton is added, it is effective to replace less than 50% by weight of the multi-component fiber with a normal fiber having a single component so as to give a feeling of fullness and elasticity. .

After mixing multi-component fibers I and II or ordinary fibers, a web is made by a random webber method, a clasper method, or a wet method, and the web is laminated in an amount to obtain a desired product thickness, needle punching and / or fluid injection. 3D entanglement of fibers by the method. The weight of the three-dimensional entangled nonwoven fabric obtained by the entanglement may be thin for the purpose of fashion, but is preferably thick for protection and the like.
The weight after the entanglement treatment is about 100 to 1500 g / m ³ .

Next, in order to impart good stretchability to the three-dimensional entangled nonwoven fabric, in the multicomponent fiber I, the removal component forming one of the phases constituting the fiber, and in the multicomponent fiber II, A step of dissolving or separating the non-elastic polymer phases constituting the fibers to remove them. By treating the three-dimensional entangled nonwoven fabric in combination with a process of shrinking, a non-elastic fineness fiber or / and its bundle fiber is obtained from the multi-component fiber I, and an elastic fiber is obtained from the multi-component fiber II. The three-dimensional entangled nonwoven fabric obtained here exhibits elasticity. This stretchability is a good stretchable entangled non-woven fabric having an elongation rate of at least 25% which does not cause structural destruction of extension in at least one direction and an elastic recovery rate of at least 80% 30 seconds after releasing the stretched state. Becomes This stretchable entangled nonwoven fabric is sliced to an appropriate thickness, or the surface is fluffed or the like to form a fiber nap surface without slicing, and a suede-like surface is finished.
Alternatively, a polymer coating mainly composed of an elastic polymer may be prepared in advance and adhered thereto, or a polymer solution or dispersion may be applied to form a coating to form a polymer coating layer, which is then finished to silver. The surface is made into a stretchable leather-like material. In order to give the leather-like material more solid feeling and rigidity, the three-dimensional entangled nonwoven fabric may contain an elastic polymer within a range not impairing the stretchability. The content is less than 35% by weight based on the weight of the elastic entangled nonwoven fabric. In addition, leather-like materials may be heated and pressed if necessary,
Coloring treatment and softening treatment may be performed. The apparent density is in the range of 0.25 to 0.75 g / cm ³ depending on the application.

The leather-like material obtained here adjusts the thickness according to the application orientation,
Cut into molds and sew. The gloves are suitable for men's and women's cold weather gloves, thick cold weather gloves for skis, ice hockey, and the like.
