Description

  The present invention is concerned with the use of a non-woven fabric as an intermediate layer of the laminate in a thin and light-weight fabric to enhance the tear strength and slip resistance which is a concern, and the appearance after washing because the non-woven fabric is not on the surface layer. The present invention relates to a thin laminate lightweight laminate fabric which is good in quality and can be worn comfortably when made into a garment.

  A moisture permeable waterproof fabric having both moisture permeability and waterproofness has a function of releasing water vapor from perspiration from the body out of the clothes, and a function of preventing rain from entering the clothes. Such moisture permeable waterproof fabric is used as a material for sports clothing, cold clothing and the like, and among them, it is often used as a clothing material for sports and the outdoors where the amount of sweating accompanying exercise is relatively large, In the fields of skiing, athletics and mountaineering, it is an essential clothing material.

  2. Description of the Related Art In the past, weight reduction and downsizing have progressed in clothing applications such as sportswear and outdoor wear where wind resistance and waterproof moisture permeability are required. However, a soft texture is required while having a minimum durability. In order to achieve weight reduction of the fabric, a yarn with fineness is to be used, but when the fineness is reached, the tear strength of the fabric decreases, and when it becomes clothing, it is broken due to friction or rubbing with other objects. Is not suitable as clothing. Generally, the tear strength is preferably 10 N or more in all circumstances, but when it becomes a fineness yarn, it becomes difficult to exceed 10 N.

Conventionally, in order to impart durability to a fine-fineness fabric, laminating a non-woven fabric and a resin film (see Patent Documents 1 and 2 below) and laminating the upper and lower portions of the non-woven fabric with a resin (see Patent Document 3 below) ) Etc are proposed.
However, although these techniques are excellent in tear strength, they have low abrasion resistance and can not maintain the feel and quality after washing.
Specifically, Patent Document 1 uses "one type selected from a group of woven fabric, knitted fabric and non-woven fabric for the surface layer, uses resin film or non-woven fabric for the middle layer, and uses knitted fabric for the back surface layer" Although the technique described in Patent Document 1 uses a non-woven fabric as the surface layer, although the tearing is improved, the quality after washing is significantly deteriorated.
Further, in Patent Document 2, “one type selected from the group of woven fabric, knitted fabric and non-woven fabric as the surface layer 1 is used, a resin film is used as the middle layer 2, and synthetic fiber multifilament yarn of 33 dtex or less is used as the back layer 3. A single circular knit fabric with 5.500 to 12,000 stitches per 6.45 cm ² is used and described as “laminated”, but the technology described in Patent Document 2 The use of non-woven fabric for the surface layer improves tearing but significantly reduces the quality after washing.
Furthermore, Patent Document 3 describes a composite sheet in which a non-woven fabric is disposed in an intermediate layer and fibers composed mainly of a thermoplastic resin are disposed in the upper layer and the lower layer of the intermediate layer. Not achieved.

  According to the present invention, it is possible to obtain a lightweight and durable laminate fabric while preventing the decrease in abrasion resistance when using a non-woven fabric for the front or back layer, and the deterioration in feel and quality after washing.

Hereinafter, embodiments of the present invention will be described in detail.
The fabric used for the surface layer of the laminate fabric of the present embodiment is any one type selected from the group consisting of woven fabric, circular knitting and tricot.
The textile, circular knit or tricot of the surface layer is composed of synthetic fiber multifilaments. The material of the synthetic fiber is not particularly limited, and polyester fiber which is polyethylene terephthalate, polytrimethylene terephthalate, polyethylene naphthalate, or a copolymer thereof, or nylon 6, 66, 610, 612 or a copolymer or a blend thereof And polyamide fibers, polyolefin fibers such as polyethylene and polypropylene, and the like. For example, in the case of using the laminate fabric for mountain climbing where strength, durability, lightness, and the like are important, it is preferable to use a woven fabric made of polyester fibers or polyamide fibers.

  In the present embodiment, the structure of the fabric forming the surface layer is not particularly limited, but taffeta and ripstop structures are preferable because they can produce a lightweight and durable fabric. Ripstop taffeta is generally arranged by aligning 2 to 5 base yarns to warp and / or weft, and weaving, but instead of aligning 2 to 5 base yarns, this is the same. Alternatively, it may be woven using a single thick yarn, or synthetic fibers multifilaments of different materials, for example, high strength fibers such as high strength polyester or high strength nylon may be distributed and woven.

  Examples of yarns constituting the fabric of the surface layer include processed yarns such as raw yarns, composite yarns, false twisting yarns, and taslan yarns, but raw yarns and processed yarns are preferable, and false twisting yarns are more preferable. This is because it is easier to finish the texture of the fabric by using the false twisting yarn rather than the raw yarn when finishing the woven product.

  The false twisted yarn may be of any commonly used pin type, friction type, nip belt type, air twisting type or the like, but the friction type is preferred from the viewpoint of productivity.

  The surface layer is made up of a round knitting such as plain (tendon), 1 × 1 tendon, kanoko, rib, double-sided (smooth), pearl, punchi, milan rib, blister, etc. It can be mentioned.

  Examples of tricot types constituting the surface layer include single denbi knitting, single cord knitting, single atlas knitting, half tricot knitting, double denbi knitting, satin knitting and the like.

  The shape of the single yarn cross section of the synthetic fiber multifilament is not particularly limited, and it may be an irregular cross section other than the round cross section. Examples of the shape of the irregular cross section include a triangle, a Y-shape, a cross, a W, a V and the like, but a round cross is preferable in terms of strength.

  The fineness of the synthetic fiber multifilament of the fabric constituting the surface layer is 5 to 35 dtex, preferably 7 to 25 dtex, more preferably 10 to 22 dtex. When it exceeds 35 dtex, the yarn is thick, and when it is made into a woven fabric, it becomes thick and hard and does not become a lightweight laminated fabric. In addition, if it is smaller than 5 dtex, the weaveability becomes difficult.

The weight per unit area of the woven fabric is preferably 10 to 50 g / m ² , and more preferably 15 to 40 g / m ² , and particularly preferably 15 to 35 g / m ² , in the case of a lighter and finished thin fabric. If the weight per unit area exceeds 50 g / m ² , although a fabric having high tear strength can be obtained, it becomes a thick and heavy fabric, and it is difficult to finish the laminate as a thin fabric. Moreover, if it is less than 10 g / m ² , although it is possible to produce a thin and lightweight fabric, the degree of difficulty in processing the weave and laminate is too high to obtain a stable laminate fabric.

  There is no restriction | limiting in particular as a loom used for weaving, A water jet room loom, an air jet room loom, and a rapier loom can be used. The woven fabric can be refined, relaxed, pre-set, and dyed according to a conventional method, and can be given post-processing such as water-repellent treatment, water absorption treatment, antibacterial treatment, deodorizing and the like, or post-processing such as calendering. .

  The non-woven fabric as the intermediate layer (the second layer) includes polyester-based, polypropylene-based, polyethylene-based, polyvinyl alcohol-based, polyamide-based, acrylonitrile-based, acetate-based, cellulose-based, polyurethane-based short fiber non-woven fabric, long fiber non-woven fabric, A non-woven fabric by the flash spinning method, a non-woven fabric by the melt-blowing method, a non-woven fabric by the electro-spinning method, etc. can be appropriately used. Moreover, what laminated | stacked those plurality can also be used. In the present embodiment, it is desirable that the non-woven fabric as the intermediate layer (second layer) be of the same type as the fabric used for the fabric of the surface layer in order to enhance the tear strength of the entire laminate fabric. As the non-woven fabric, a long-fiber non-woven fabric is preferable, and since the higher the strength of the non-woven fabric itself can enhance the tear strength as a laminate, polyesters, polyamides and polypropylenes are preferable, and polyesters and polyamides are more preferable. preferable.

10-40 g / m < ² > or less is preferable, and, as for the fabric weight of the nonwoven fabric used for an intermediate | middle layer (2nd layer), 10-30 g / m < ² > is more preferable, More preferably, it is 20-30 g / m < ² >. When the weight per unit area exceeds 40 g / m ² , the tear improves but the laminate itself becomes thick, and when it is smaller than 10 g / m ² , the processability as a laminate becomes difficult and the tear strength as a laminate does not improve.

  In the present embodiment, the tear strength is improved by using a non-woven fabric as the intermediate layer of the laminate fabric. The cause is as follows. For example, since the fabric used in the first layer has yarns arranged only in the warp and weft directions, measurement of tear strength in a certain direction by JIS-L-1096 8.15.5 D method (Benduram method) Here, the strength of the yarn itself affects the tear strength. However, although non-woven fabric is not high in tear strength as a single non-woven fabric because the constituent yarns are randomly arranged, it is laminated with the woven fabric to play a role of reinforcement when the woven fabric is torn apart, and laminate fabric The tear strength as a whole will be dramatically improved.

  The resin film used for the third layer of the laminate fabric of the present embodiment is not particularly limited as long as it has sufficient flexibility for clothing use, and, for example, polyurethane resin, polyethylene terephthalate, poly Films of polyester resins such as butylene terephthalate, polyolefin resins such as acrylic resins, polyethylene, and polyolefins, polyamide resins, vinyl chloride resins, synthetic rubbers, natural rubber, and fluorine-containing resins can be used. Moreover, although the direct coating method and the laminating method are mentioned as a method of laminating | stacking a resin film, limitation in particular is not carried out.

  The direct coating method is a method in which the resin is directly coated in a uniform thin film form on one side of the fabric to form a film, and a wet method in which the fabric is allowed to pass through water to form a film, and a dry method to form a film by drying. There is. The laminating method is a method in which an adhesive is applied on a resin film prepared in advance to laminate a fabric.

The moisture permeability of the resin film can be achieved by forming a large number of micropores in the film to form a porous film or using a resin having moisture permeability to form a nonporous film, but imparting moisture permeability The method is not particularly limited.
The porous film is, for example, a resin film having a large number of micropores of such a diameter as to allow water vapor having a diameter of 0.0004 μm to permeate and water droplets having a diameter of 100 μm or more not to permeate, and to have both high moisture permeability and waterproofness.
In addition, non-porous film is a film that exhibits moisture permeability when water vapor intrudes into the amorphous part where the bond between molecules is weak, and because it is non-porous, the film thickness can be reduced. It is characterized in that it can be done and has high waterproofness.

  In the present embodiment, a laminate of a surface layer (first layer) which is any one selected from the group consisting of woven fabric, knitted fabric and tricot and a non-woven fabric which is an intermediate layer (second layer), the intermediate layer (2 In order to laminate the layer layer) and the back surface layer (third layer) which is a resin film layer, a manufacturing technique such as a laminating method of bonding with an adhesive or the like can be used.

  For example, for bonding of the woven fabric layer, the non-woven fabric layer and the resin film layer, for example, a method of interposing and bonding an adhesive between the respective layers, a thermocompression bonding method of thermally pressure bonding and adhering can be used. In such bonding or thermocompression bonding, the entire surface of the laminated surface may be completely in contact or may be partially in point form, and it is not particularly limited. As the type of the adhesive, in addition to the thermoplastic resin adhesive, a curable resin adhesive which reacts and cures by heat or light can be used. Examples thereof include adhesives such as polyester resins, polyamide resins, polyurethane resins, silicone resins, acrylic resins, polyvinyl chloride resins, and polyolefin resins, and more preferably polyurethane resin adhesives.

  Although the coverage by the adhesive is not particularly limited, generally, the higher the coverage, the higher the peel strength but the lower the tear strength, and the lower the coverage, the higher the tear strength but the lower the peel strength. It is preferable to determine the tear strength and the peel strength while adjusting the coating ratio of the adhesive and the amount of the adhesive while observing the performance of the fabric of the surface layer, the nonwoven fabric of the intermediate layer and the like.

  Using the above method, a surface layer (first layer) composed of synthetic multifilaments, which is selected from the group consisting of woven fabric, circular knitting and tricot, and an intermediate layer (second layer) which is a non-woven fabric are adhered, By bonding the intermediate layer (second layer) and the back surface layer (third layer) which is a resin film layer, the laminate fabric of the present embodiment can be produced.

  As for the tearing strength of the laminated fabric manufactured in this way, in order to endure practical use as sports clothing, 10-50N is preferable and 15-30N is more preferable. The burst strength of the laminate fabric is preferably 5 N / 2.54 cm, more preferably 6 N or more.

Also, the basis weight of the laminate fabric is preferably 50 g / ^{m 2} or more 150 g / ^{m 2} or less, 50 g / ^{m 2} or more 100 g / ^{m 2} or less is more preferable.

Air permeability of the laminate fabric is preferably from 0.3cc ^/ cm 2 · sec, more preferably not more than 0.1cc ^/ cm 2 · sec. The lower the permeability, the better, and the lower limit is 0 cc / cm ² · sec.

  The laminate fabric of the present embodiment not only has high tear strength, but also has a high abrasion property because the nonwoven fabric is not disposed on the front or back, and the appearance is maintained without a change in appearance such as fuzz after repeated washing. Do.

  In another embodiment, from the viewpoint of protection of the resin film layer that is the back surface layer, a fabric selected from the group consisting of synthetic multifilament woven fabric, knitted fabric, and tricot is further bonded to the resin film that is the back surface layer. Depending on the purpose.

  In the present invention, the second layer means an “intermediate layer” located between the first layer which is the surface layer described above and the third layer which is the back surface layer, and the second layer The middle layer) can be a single layer, but it is not the same, and multiple layers of the same layer or multiple layers of different layers may constitute one layer as a whole.

  The laminate of the present embodiment is not only high in tear strength and slip resistance, but also has no deterioration in the appearance after washing because the nonwoven fabric is not on the front or back of the fabric, and is excellent in wearability and widely in the field of clothing. It can apply. In particular, clothing often rubs with each other when worn, suitable for outer covers such as windbreakers, down jackets, sportswear, outdoor wear, tents, sleeping bags, umbrellas, etc., and is worn particularly in a harsh environment, contact friction It can be suitably used for sportswear and outdoor wear, which is often done. In addition, since the laminate fabric of the present embodiment is characterized by being thin in weight and excellent in wear resistance, it can be particularly suitably used for the above-described thin and light-weighted clothing.
