Abstract

A multi-layer waterproof clothing fabric comprising a thermal insulation unit, the thermal insulation unit having a base fabric layer, the base fabric layer having an outer surface, the waterproof garment fabric further comprising a waterproof joint bonded to the outer surface of the base fabric layer surface layer. By providing the waterproof surface layer on the outer surface of the base fabric layer, it is possible to prevent water molecules from penetrating into the heat retention unit, thereby preventing the heat retention unit from increasing in weight due to water absorption. Since the water molecules cannot penetrate the thermal insulation unit, the same thermal insulation effect can be provided in the case of reducing the thickness to improve the wearing comfort.

Description

Multi-layer waterproof clothing fabric

The present invention relates to a fabric, and more particularly to a waterproof clothing fabric suitable for use in a waterproof and cold-proof field and having a multi-layer structure.

It is generally suitable for use in a waterproof clothing fabric such as the three-iron sports and diving field, and basically comprises a foam insulation layer made of closed-cell rubber, and a base fabric layer bonded to the foam insulation layer, The base fabric layer generally adopts 100% polyester or polyamide fiber single-face knitted fabric, and utilizes the thickness of the foam insulation layer to block the body temperature loss, so as to achieve the purpose of heat preservation.

Although the waterproof clothing fabric can achieve the effect of heat preservation, the foam insulation layer made of rubber has high density and heavy weight, and the base fabric layer made of the knitted fabric absorbs external water molecules and increases the weight. Therefore, it is easy to know that the waterproof clothing fabric is uncomfortable to wear due to water absorption and heavy weight. Since the base fabric layer absorbs water and lacks the heat preservation effect, it is known that the waterproof clothing fabric needs to increase the thickness to achieve the purpose of keeping warm from the cold. The demand for this function also makes the waterproof garment look cumbersome when worn.

Accordingly, it is an object of the present invention to provide a multi-layered waterproof garment fabric that can improve at least one of the disadvantages of the prior art.

Thus, the waterproof garment fabric of the present invention comprises a thermal insulation unit having a base fabric layer, the base fabric layer having an outer surface, the waterproof garment fabric further comprising a surface bonded to the outer surface of the base fabric layer Waterproof skin.

The utility model has the advantages that: by providing the waterproof surface layer on the outer surface of the base fabric layer, water molecules can be prevented from infiltrating into the heat preservation unit, and the heat retention unit is prevented from increasing in weight due to water absorption, and further, since water molecules cannot penetrate The thermal insulation unit, the present invention can provide the same thermal insulation effect in the case of reducing the thickness to improve the wearing comfort.

Referring to Fig. 1, a first embodiment of the waterproof garment fabric of the present invention is suitable for use in the fields of waterproofing and cold protection such as three-iron sports, diving, etc., and can be made into clothing and wearing articles. The cloth comprises a thermal insulation unit 1 and a waterproof skin 2 bonded to the thermal insulation unit 1. The thermal insulation unit 1 has a foam insulation layer 11, a base fabric layer 12 having an area equivalent to the foam insulation layer 11, and an adhesive layer 13 for bonding the base fabric layer 12 to the foam insulation layer 11.

The foamed thermal insulation layer 11 is formed by foaming a rubber material, preferably a rubber material having waterproof and low-density properties, and the specific material may be selected from at least one of: styrene-butadiene rubber (SBR), natural rubber (NR), and chlorine. Butadiene rubber (CR), butadiene rubber (BR), EPDM, nitrile rubber (NBR), ethylene-vinyl acetate copolymer (EVA) and thermoplastic elastomer (TPE) . Preferably, the rubber material has a separate gas chamber, and the density is preferably less than 1, and the thickness is between 0.3 and 10 mm. In this embodiment, a low density neoprene rubber is used.

The material of the base fabric layer 12 is not particularly limited, and may be at least one of a knitted fabric, a plain woven fabric, an artificial leather, a rubber foamed cotton, or a paper product, or two or more of the aforementioned fabrics or film stickers. In the present embodiment, a composite fabric having a stretchability, the base fabric layer 12 has an outer surface 121 away from the foam insulation layer 11, and a foam insulation layer 11 Inner surface 122.

The adhesive layer 13 bonds the inner surface 122 of the base fabric layer 12 to the foamed heat insulating layer 11, which is coated by an adhesive, and the adhesive may be selected from at least one type: neoprene rubber (CR). Polyurethane (PU), Acrylic resin, ethylene-vinyl acetate copolymer (EVA), the adhesive may be aqueous, solvent or solventless.

The waterproof surface layer 2 is made of a thermoplastic elastomer (TPE) resin as a main component, and has waterproof and anti-slip properties. The thermoplastic elastomer resin may be selected from at least one type: thermoplastic polyurethane (TPU), heat. Plastic rubber (TPR), polystyrene elastomer (TPS), and thermoplastic polyolefin elastomer (TPO).

In the embodiment, the waterproof fabric is fixedly combined with the base fabric layer 12 and the foam insulation layer 11 by using the adhesive layer 13, and the outer surface 121 of the base fabric layer 12 is coated with waterproof. Coating to form the waterproof skin 2. Since the waterproof surface layer 2 is away from the human body when in use, that is, toward the outside, the waterproof surface layer 2 not only has a non-slip effect during wearing, but also prevents water molecules from penetrating into the base fabric layer 12, that is, In the embodiment, the waterproof surface layer 2 is disposed on the outer surface 121 of the thermal insulation unit 1. In addition to avoiding the weight increase of the thermal insulation unit 1 due to water absorption, since water molecules cannot penetrate the thermal insulation unit 1, the thickness can be reduced. The same insulation effect is provided in case to improve the comfort of the fabric when worn.

Referring to FIG. 2, a second embodiment of the waterproof garment fabric of the present invention also includes the thermal insulation unit 1 and the waterproof surface layer 2. The thermal insulation unit 1 has the foam insulation layer 11, the base fabric layer 12 and the adhesive layer 13 In addition, there is an inner layer 14 attached to the inner side of the foam insulation layer 11, and the waterproof cloth fabric further comprises a protective layer 3 bonded to the outer side of the waterproof surface layer 2, that is, the protective layer 3 and the base cloth. The layers 12 are respectively located on opposite sides of the waterproof skin 2. The protective layer 3 is selected from at least one of water-based polyurethane, oil-based polyurethane, silicone resin, Acrylic resin, and fluorine-based resin, and is preferably waterproof, low-resistance, and scratch-resistant. The polyurethane (PU) material is provided on the outer side of the waterproof surface layer 2, and in addition to the effects described in the first embodiment, the cloth can also have the advantages of smooth touch and good scratch resistance. .

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
