[Industrial Application Field] The present invention relates to a multilayer fabric having breathability and waterproofness. More particularly, the present invention relates to breathable fabrics suitable for waterproof garment applications. [Prior Art] Conventional protective fabrics have been manufactured mainly by coating the surface of a knitted fabric with a resin film. However, this fabric ends up sacrificing breathability in order to ensure sufficient waterproofness. As a solution to this problem, JP-A No. 56-26076 proposes to form a film made of a synthetic polymer mainly composed of polyurethane polymer, which contains micropores in the micron scale, and to make these micropores communicate with each other. It has been proposed that air permeability can be achieved through this method. However, with this method, there is a limit to the number of foam holes per unit area, and in order to obtain sufficient waterproofness, the air permeability must be reduced to 0.5.
The air permeability must be less than cc/cm 2 · seconds, and the air permeability has not yet been fully satisfied. Further, in order to uniformly scatter the micropores, the permissible range of manufacturing conditions is narrow and a long manufacturing process is required, which is not industrially advantageous. Normally, the water released from the human body includes constantly evaporating water and sweat for regulating body temperature during exercise. The former is approximately 23 g/hr·m 2 at a comfortable temperature and under resting conditions, and the latter reaches over 100 c.c./hr·m 2 during intense exercise. As mentioned above, conventional clothing made of waterproof fabric prevents moisture from the body from exiting the fabric, resulting in high humidity inside the fabric, resulting in a feeling of heat and discomfort. . Recently, there are moisture-permeable waterproof fabrics in which a moisture-permeable film is adhered to a woven or knitted fabric, but because the breathability is insufficient at less than 0.5cc/ m2・sec, the amount of released moisture to the outside of the fabric is insufficient. That's enough. On the other hand, the target value for waterproof performance for clothing is generally
400mmH 2 O or more is required. However, it is difficult to achieve this target value with conventional waterproof fabrics that have adequate breathability. [Problems to be solved by the invention] The purpose of the present invention is to solve the above-mentioned technical problems,
Fabrics that have a good balance of breathability and waterproofness, which have traditionally been difficult to achieve at the same time, especially
To provide a fabric capable of efficiently discharging moisture sweated during exercise to the outside of the fabric. [Means for solving the problem] That is, the breathable waterproof fabric according to the present invention has a single yarn fineness of 0.005 to 2.0 deniers and a fiber packing density of 5.
It is characterized in that a fiber sheet having water-diffusing and water-retaining properties is integrally laminated on at least one side of a fiber sheet having water repellency of ~30%. The feature of the breathable waterproof fabric according to the present invention is that a water-repellent fiber sheet having breathability and waterproof properties is laminated with a fiber sheet having excellent water diffusivity. A water-repellent fiber sheet without a water-diffusing sheet has breathability, and when one side becomes humid, it functions to ventilate and transfer the moisture to the other side. When only such a water-repellent fiber sheet is used, the rate of water dissipation to the outside of the fabric is faster than that of conventional waterproof fabrics, but the sweat from the body evaporates once on the skin surface and then Since the sweat evaporates to the outside of the fabric, during intense exercise where the sweating action exceeds the evaporation rate, sweat remains on the skin surface and tends to cause a feeling of heat and discomfort. The breathable and waterproof fabric of the present invention has a structure in which a water-diffusing sheet is laminated and integrated on one side of the water-repellent fiber sheet as described above, so absorbed sweat is diffused and converted into water vapor on a large surface. This will prevent you from feeling stuffy and uncomfortable. The "water-repellent fiber sheet" used in the present invention includes:
Sheet structures made of fibers that themselves exhibit water repellency, such as polypropylene fibers, polyethylene fibers, and polytetrafluoroethylene fibers, and sheet structures made of fibers that do not themselves exhibit water repellency, such as polyester fibers and polyamide fibers, are water repellent. Examples include those imparted with water repellency through post-processing using a processing agent. These fiber sheets may be nonwoven fabrics made from short fibers, long fiber nonwoven fabrics made by laminating melt-proofed fibers, needle-punched carded web nonwoven fabrics, etc., but are not limited to these. . In particular, a fiber sheet produced by a melt-blown method is preferable. This is because this fiber sheet has fine fibers, uniform basis weight and thickness, and is less likely to generate pinholes. Water-repellent finishing for making the fiber sheet water-repellent through post-processing can be done by a normal method, for example,
Known water-repellent agents such as fluorocarbon resins such as acrylic acid perfluoroalcohol, silicone resins such as dimethyl silicone, paraffin resins, and wax-based resins are padded or immersed into the fiber structure during yarn production or sheet-like fiber structures. It may be applied by methods such as , spraying, and exhaustion. Furthermore, if necessary,
After applying the water repellent agent, heat treatment may be performed. The fibers constituting such a fiber sheet have a single fiber fineness of 0.005 to 2.0 denier, preferably 0.01
Use one in the range of ~1.0 denier. If it is less than 0.005 denier, the single fiber strength will be low and the handling properties during subsequent processing will be poor. Furthermore, the close contact between the single fibers is large, making it impossible to obtain sufficient air permeability. on the other hand,
If it exceeds 2.0 denier, breathability will be improved, but sufficient waterproofness will not be obtained. Such fine-grained fibers can be produced by methods such as dissolving and removing one of the seabird fibers, which consists of two components such as a polyamide component and a polyester component, or splitting the fibers by thermal treatment or physical treatment after spinning. can be manufactured. Although the basis weight of the fiber sheet is not particularly limited, it is preferably 30 to 120 g/m 2 . The fiber filling rate α (%) expressed as (p′/p)×100 of the fiber sheet [p′ is the apparent density of the fiber structure, p is the true density of the fibers] is 30≧α≧5, preferably is 25
The range is ≧α≧10. That is, the filling rate is 5%
If it is less than this, fiber gaps will become large and sufficient waterproofness will not be obtained. Furthermore, if the filling rate exceeds 30%, sufficient air permeability cannot be obtained. The "water-diffusible sheet" used in the present invention is a sheet-like structure that absorbs water and exhibits diffusibility, water retention, and quick-drying properties. A guideline for water absorption and diffusivity is:
Water should be rapidly absorbed, with an absorption rate expressed by the JIS L-1079 water absorption test method of 60 seconds or less, preferably 10 seconds or less, and more preferably 1 second or less. If the absorption speed exceeds 60 seconds, sweat cannot be sufficiently transferred from the skin surface or underwear surface to the water-diffusing sheet. The water-diffusing sheet used in the present invention must have appropriate water retention properties. Water retention is a property that absorbs water from the skin surface or underwear surface and prevents the water from transferring to the skin surface or underwear surface again due to external pressure. The maximum water retention rate (average water content due to centrifugal dehydration) based on the sheet weight is 5% or more, 80%
The following are preferred. If the water retention amount is less than 5%, the amount of water absorption is insufficient, and discomfort such as "stuffiness" cannot be alleviated. In addition, in cases where the proportion exceeds 80%, the surface feels damp and the discomfort does not go away. The materials that make up the water-diffusing fiber sheet include:
Any of waterproof fibers such as cotton and rayon, fibers with improved water absorption based on the capillary principle such as ultrafine fibers, and fibers with improved water absorption using a hydrophilic finishing agent can be used.
As a method for preparing a fiber sheet having appropriate water retention, for example, water absorbent fibers such as rayon fiber (its maximum water retention rate is 100% or more) and non-water absorbent fibers such as polyethylene terephthalate fiber are combined. A method of interweaving may be considered. Furthermore, since non-water-absorbing fibers have insufficient water retention, it is desirable to subject them to water-absorbing treatment. The water-diffusing sheet may be in the form of a woven fabric, knitted fabric, or non-woven fabric. Further, it is preferable that the water-diffusing sheet has a two-layer structure in which one or more layers having water absorption and diffusion properties are combined with a water-permeable layer having low water-retention properties; such a two-layer structure has the following properties: It is preferable to use a water-permeable layer surface that does not have water-retentive properties on the skin side because the surface always feels dry. The water-diffusing sheet has air permeability, preferably one having air permeability equal to or higher than that of a waterproof water-repellent fiber sheet. Methods for laminating and integrating a water-repellent fiber sheet and a water-diffusive fiber sheet include a method of attaching a hot melt resin to either the web layer or the knitted fabric and heat-bonding it; Any method can be used, such as applying adhesive and bonding under pressure, overlapping the web layer and knitted fabric and integrating them using high-frequency welding or ultrasonic waves, or laminating and integrating them using sewing thread. You can also do it. however,
When laminating and integrating the layers, it is necessary to do so in a manner that does not impair air permeability. Therefore, for example, it is desirable to arrange and laminate the adhesive or hot melt resin in the form of dots, cotton, or mesh. Furthermore, when the waterproof fabric of the present invention is made into a final product, a outer material is generally attached, and it is preferable that such outer material is laminated in a similar manner. In addition, although the lamination and integration may be performed by overlapping and integrating at the time of sewing, in consideration of ease of handling, it is preferable to integrate by the method described above prior to sewing. [Effects of the Invention] The breathable waterproof fabric of the present invention is excellent in both breathability and waterproofness. Because it has excellent breathability, the air inside the clothes can be ventilated through exercise. Furthermore, since it has a water-diffusing layer on one side, it actively helps evaporate water and eliminates the feeling of heat and humidity. Therefore, the breathable waterproof fabric of the present invention can be used for waterproofing purposes such as sports wear such as jogging wear, diaper covers, rain gear, hats, work clothes, shoes, and gloves. [Example] The present invention will be specifically described below with reference to Examples. Example 1 Single yarn fineness 0.03 obtained by melt blow method
A web of polyethylene terephthalate fibers with a denier and a basis weight of 30 g/m 2 is subjected to a relaxation process, then immersed in the bath of Process 1 below, and the reduction rate is reduced using a mangle machine.
After squeezing it evenly to 100%, dry it at 100℃ for 2 minutes,

Two types were created: [Invention Product 1] and 40% rayon blend [Invention Product 2]), and were subjected to the usual dyeing and finishing process. Furthermore, one side of the polyamide-based hot melt adhesive resin (Nippon Rilsan Platamide H/
O2P) at 200 points/10 at intervals of 1 square inch
Dots were dispersed at a concentration of g/m 2 . Next, using a hot press machine, the water-repellent web and knitted fabric produced by the above method were bonded together at 140° C. for 20 seconds under a pressure of 3 kg/cm 2 to obtain a breathable waterproof fabric. Using this breathable waterproof fabric and polyethylene terephthalate fiber plain woven fabric, a three-layer structure was made with the water-repellent nonwoven fabric in the center and the water-diffusing sheet on the skin, and the edges were sewn to create the upper and lower parts of the rain gear. For comparison, instead of the above-mentioned water-diffusing sheet (rayon/polyester fiber tricot knitted fabric), a tricot knitted fabric (comparative product 1) made from only polyester fibers and a tricot knitted fabric made in the same way from only rayon were used. Knitted fabric (comparison product 2)
A laminated fabric was created using Outer garments and underwear were sewn from the inventive product and the comparative product, and tested for waterproofness and breathability. temperature
Table 1 shows the results of a comparison of the amount of residual moisture remaining in outer clothing and underwear after 20 minutes of strenuous exercise on a bicycle in an environment of 20°C and 65% humidity. The product of the present invention had less residual moisture in both underwear and outer clothing than the comparative product, making it ideal as rain gear.
