The present invention relates to a moisture-permeable waterproof fabric with excellent heat retention. Moisture-permeable waterproof fabrics are used for ski wear, training wear, parkas, raincoats, tents, etc. Conventional moisture-permeable waterproof fabrics have some air retention properties by using a polymer layer having interconnected micropores, but they do not have good heat retention properties. Furthermore, it has no reflective effect on radiant heat from heat sources such as body temperature. Therefore, when used in cold-weather clothing such as ski wear, it is necessary to use a large amount of filler such as feathers to supplement the heat retention and insulation properties. However, if a large amount of batting is used, the clothing becomes thick, which reduces mobility and makes it difficult to exercise. The present invention improves the above-mentioned problems and provides a heat-retaining product that has excellent heat retention without impairing moisture permeability or waterproofness.
To provide breathable waterproof fabric. The gist of this invention is to provide a polymer layer discontinuously formed on at least one surface of a fiber base fabric or a polymer layer (A layer) having a large number of interconnected micropores, and a heat ray reflective metal fine piece of This is a heat-retaining and moisture-permeable waterproof fabric in which polymer layers (B layers) containing 70% by weight (based on the weight of the B layer polymer layer) and having a large number of communicating micropores extending from the surface to the inside are laminated in sequence. As the fiber base fabric used in this invention, woven fabrics, knitted fabrics, non-woven fabrics, etc. made of synthetic fibers such as nylon and ester, as well as chemical fibers and natural fibers, singly or in combination, are generally used. Polymers used in layer A, which is a discontinuous polymer layer or a microporous polymer, and layer B, which is a microporous polymer layer containing fine metal particles, include polyurethane, polyacrylic ester, polyamide, and polyester. Polymers such as vinyl chloride and polyvinylidene chloride can be used alone or in combination. Among these, polyurethane polymers are particularly suitable. B layer contains 15-70% by weight of heat-reflective metal particles.
(Polymer layer for layer B) This is a polymer layer having a large number of communicating micropores communicating from the surface to the inside, and is laminated on the fiber base fabric via layer A. All solid metals such as aluminum tin, nickel, silver, magnesium, and chromium can be used as the heat ray reflective metal particles, but it is preferable to use aluminum, which has a low specific gravity and has a high heat ray reflective effect. The shape of the metal fine pieces may be round, square, or flat, and those with a long axis of about 0.1 to 30 μm are generally suitably used. If the proportion to the B-layer polymer is less than 15% by weight, the heat ray reflection effect will be poor, and if it is more than 70% by weight, problems will arise in the uniformity of the microporous polymer film and the falling off of fine metal pieces, which is not preferable. A more preferable mixing ratio is 20 to 50% by weight. Also,
In order to further increase the heat ray reflection efficiency, a thin transparent polymer film that does not completely fill the small pores on the surface can be laminated on the microporous polymer film containing fine metal particles. There are many small pores on the surface of layer B. The pore diameter is
The thickness is preferably 5 μm or less, more preferably 3 μm or less. Furthermore, inside the film, there are cavities that are continuous with the small pores on the surface and communicate vertically and horizontally. The cavity diameter is 1
Preferably, the majority is in the range of ~20 μm.
The thickness of layer B is not particularly limited, but may be 3
~100 μm is preferred. Layer A is a discontinuously formed polymer layer or a polymer layer having a large number of interconnected micropores. A
The layer is interposed between the B layer and the fiber base fabric, and enhances the adhesion strength between the two and contributes to improving waterproofness. The discontinuously formed polymer layer is a network-like polymer layer, a polymer layer formed in an appropriate size and scattered on a fiber base fabric, or the like. The diameter of the majority of pores in the polymer layer having interconnected micropores is preferably in the range of 1 to 20 μm. The thickness of such a polymer layer can be selected arbitrarily, but
1 to 50 μm is preferable, more preferably 2 to 20 μm
It is m. The heat-retaining and moisture-permeable waterproof fabric according to the present invention has the above-mentioned structure, and the surface is mixed with heat-reflecting metal particles, which effectively reflects radiant heat from the inside such as body temperature, and has heat-retaining and heat-insulating properties. improves. In addition, it has a large number of communicating micropores that communicate from the surface to the inside, and maintains sufficient moisture permeability without impairing waterproofness. An example of manufacturing the heat-retaining and moisture-permeable waterproof fabric according to the present invention will be described below. A fibrous base fabric is coated with an organic solvent solution containing 5 to 40% by weight of the polymer. Coating methods include knife coater, reverse roll coater,
A known coating machine such as a kiss roll coater or a gravure coater can be used, and a dry coating method is preferred. Generally, when the dry solid content of the polymer is 5 g/m 2 or less, a discontinuous polymer layer with a seemingly network-like structure is formed. When applying a polymer of 10 g/m 2 or more, a polymer having a large number of interconnected micropores is used. When gravure coating is performed, a discontinuous polymer layer is formed. Next, after performing dry coagulation or wet coagulation, a 5 to 40% by weight organic solvent solution of a polymer containing 15 to 70% by weight of metal particles is coated on this layer in the same manner as above, and then dry coagulation or wet coagulation is performed. Perform wet coagulation. Alternatively, a polymer solution containing fine metal pieces may be applied to a release paper using the coating machine described above, solidified, and then laminated onto the polymer layer (layer A). Additives such as a dispersant, a foaming agent, a coloring agent, a curing agent, a poor solvent for the polymer, and a surfactant can be used in the polymer solution as necessary. Furthermore, in order to further improve waterproofness, a water repellent can be applied to the laminated fabric obtained as described above.
Fluorine-based, silicon-based, zirconium-based, etc. can all be used as water repellents. The present invention is as described above, and the heat-retaining, moisture-permeable waterproof fabric of the present invention has excellent heat retention without impairing moisture permeability, and is therefore widely applicable to cold-weather clothing such as ski wear, mountain parkas, and warm-up jackets. can. Next, the present invention will be described with reference to examples, but the present invention is not limited thereto. The following measurement method was used to compare the performance of the laminated fabrics obtained in the examples. (Measurement method) Water pressure resistance JIS L1092 Moisture permeability JIS K6328 Heat insulation (thermal transmission coefficient)
Place an insulated container with an opening at the top. Place the sample in the opening, touch the detection end of the heat flow meter to the sample surface, and check the constant temperature chamber temperature (T 1 °C) and the temperature inside the insulated container (T 2
The heat flow (Q
Kcal/m 2 ·h) is measured, and the heat transmission coefficient K is determined from Q=K(T 2 −T 1 ). Example 1 Water-in-oil polyurethane resin dispersion (solid content 20
%) to 100 parts by weight, 5 parts by weight of methyl ethyl ketone, 25 parts by weight of water, and 2 parts by weight of an isocyanate crosslinking agent (Sofranate #3001, containing 7.5% NCO, manufactured by Nippon Soflan Kako) were dissolved and mixed in a stirring tank.
Prepare a paste-like coating dispersion. Dyed nylon 66 taffeta 70d nylon 66 weave density 210 fibers were pretreated by pressing with a thermal calendar roll at 180°C, and the above dispersion was applied to this base fabric with a knife coater at 50°C, 70°C, and 90°C. Dry and solidify in a relatively low-temperature drying range of ℃ to a dry solid content of 5g/m 2
A coating film was formed. Further, 8 parts by weight of aluminum paste (STAPA-15HK metal content 65% average particle size 5 μm manufactured by Asahi Kasei Industries) was dissolved in 100 parts by weight of the above coating dispersion and mixed in a stirring tank to coat the coating dispersion in the form of a silver paste. Coating and laminating on the surface of the film using a roll coater and drying and solidifying in a low temperature drying range of 40℃, 60℃, and 80℃ to achieve a dry solid content of 25
A coating film of g/m 2 was laminated. This coating fabric is coated with a fluorine water repellent (Sumifl oil).
A 2.5% aqueous solution of EM-11 (Sumitomo Chemical, 18% solid content) was applied to the patch, dried and then baked at 160°C for 1 minute. The results are shown in Table 1. Comparative Examples 1 and 2 of Example 1 are a case where nylon 66 taffeta was used in the same manner as in Example 1, and the amount of aluminum paste mixed into the coating dispersion was reduced to 4 parts by weight (Comparative Example 1), and aluminum paste. Table 1 shows a comparison of the performance of coated fabrics with the same amount of solid content when the amount is increased to 70 parts by weight (Comparative Example 2). There is almost no difference, but the heat retention is poor, and in the case of Comparative Example 2, the heat retention is good, but it is found that the aluminum powder easily falls off due to surface abrasion (Gakushin type friction test method), so it is not practical. Example 2 Polyester smooth (fabric weight 320g/m 2 ) 180
Dry heat setting was carried out at 30 sec at °C, and then the same coating dispersion as in Example 1 was coated in the same manner by applying pressure with a hot calendar roll. The solid content adhesion amounts were 10 g/m 2 and 30 g/m 2 , respectively. This coated fabric is coated with a fluorine water repellent solution (Sumifloil,
EM-12, 2% by weight, Sumitex Resin M-3,
0.3% by weight, Sumitex Resin ACX, 0.3% by weight,
Example 2 in Table 1 shows the results of patch treatment with Sumitex Sofer LK-1 (0.5% by weight), drying, and baking at 170°C for 1.5 minutes. Example 3 Dyed warp-stretch nylon 66 stretch fabric (both warp and warp threads are 70d nylon processed thread weaving density: 305)
In the same manner as in Example 1, the solid content adhesion amount was 7.
Table 1 shows the results of the same water repellent treatment and baking treatment as in Example 1, with the amount of coating dispersion mixed with aluminum paste being about twice as large as 50 g/m 2 and 50 g/m 2. Shown in 3. Example 4 A dyed nylon taffeta made of 6.6 nylon 70 denier fabric with a weave density of 210 fibers was pretreated by pressing with a thermal calendar roll at 180°C, and polyurethane (Crisbon 8166, solid content 15%) was applied to this base fabric.
was applied at a concentration of 5 g/m 2 and dried and solidified in the same manner as in Example 1. In addition, polyurethane (Chrisbon 8166. Solid content
A polymer solution prepared by mixing and dissolving 30 parts by weight of aluminum paste, 5 parts by weight of aluminum paste, and 65 parts by weight of dimethylformamide was applied to the polyurethane coated surface of nylon taffeta at a coating weight of 25 g/m 2 using a knife coater. The material was immersed in water containing 5% by weight of the material to solidify it. The obtained coated fabric was subjected to water repellent treatment in the same manner as in Example 1. Display the results -
This is shown in Example 4 of 1. Example 5 The polymer solution used in Example 4 was applied to release paper at a concentration of 20 g/m 2 using a knife coater, and dried and coagulated. Next, an adhesive (Chrisbon 8166, mixed with a solid content of 10% by weight) was applied to the film surface at a concentration of 15 g/m 2 , and when it became semi-dry, the nylon taffeta used in Example 4 was applied. It was crimped and fixed with a hot pressure roll. Next, water repellent treatment was performed in the same manner as in Example 1. The results are shown in Example 5 in Table 1.
