(Industrial Application Field) The present invention relates to a method for producing a coated fabric that is highly durable and has a good feel. (Prior Art) Coating processing has conventionally been a common method for imparting waterproof and windproof properties to fabrics, or for obtaining sealing effects, surface changes, and the like. Various resins are used for coating clothing, but polyurethane resins are particularly useful for coating fabrics with a soft texture because they can easily form microporous films or films with stretch properties. It is easy to obtain and has been widely used in conjunction with the recent software-oriented trend. Generally, when a fabric is coated, the texture hardens due to the penetration of the coating resin into the fabric, and even if a soft resin such as polyurethane resin is used, the hardening of the texture is unavoidable. Therefore, it is possible to improve the texture by controlling the penetration of the coating resin into the fabric.
Penetration is related not only to texture but also to adhesion.
Moreover, the two have a contradictory relationship. For this reason,
There is a method in which the fabric is thermally calendered and the surface of the fabric is pressed to smooth it, and a method in which a water or oil repellent such as a fluorocarbon compound is applied to the fabric in advance to prevent penetration. (Japanese Unexamined Patent Publication No. 58-144178) Furthermore, JP-A No. 59-30966 discloses that a fabric using split-peelable composite fibers made of polyamide and polyester is subjected to thermal calendering treatment and polyurethane resin coating treatment. is disclosed. (Problems to be Solved by the Invention) However, it is true that the higher the pressing pressure and the higher the temperature, the higher the thermal calender treatment becomes.
The smoothing effect is promoted and the penetration prevention effect is enhanced, but on the other hand, when pressure smoothing is applied to ordinary fabrics, the texture is hardened and the soft texture of the polyurethane resin is reduced. In addition, water-repellent and oil-repellent treatments have only a slight penetration prevention effect, and even when a water-repellent or oil-repellent agent is combined with a coating resin, a decrease in adhesion is observed. In addition, attempts have been made to combine thermal calendaring with water-repellent and oil-repellent treatments, as well as use of split-peelable fibers, but the adhesion between the coating film and the fabric is not sufficient and the durability is poor. Ta. Therefore, conventional coated fabrics with a soft texture are limited to applications where durability with an adhesive strength of about 0.4 kg/cm is sufficient, and applications such as sports clothing or applications where the coated surface is used on the front side (adhesive strength of 0.9 kg/cm)
It has been difficult to develop coating fabrics that have a soft texture and high adhesive strength, especially 1.5 to 2.0 Kg/cm or more. The present invention aims to provide a coated fabric that satisfies such demands and has both durability and a soft feel. (Means for Solving the Problems) The present invention uses a dissolvable split type composite fiber whose single filament fineness after splitting is 1 denier or less.
It is obtained by weaving a high-density fabric of 15,000 fibers/parallel inch or more, fibrillating the composite fibers by melting, calendering at least one side of the fabric, and then forming a polyurethane film on the same side. The high-density fabric referred to in the present invention is a fabric containing thermoplastic synthetic fibers having a single filament fineness of 1 denier or less after splitting, and examples of the thermoplastic synthetic fibers include:
Polyamide fibers, polyester fibers, acrylic fibers, or easily soluble conjugate fibers containing copolymer components that are removed by post-processing can be used. In addition, the single yarn fineness may be such that some of the fibers constituting the fabric satisfy the above range, and even if fibers with multiple types of single yarn fineness are used, some of the fibers constituting the fabric may be natural. The fiber may be, for example, cotton, linen, silk, wool, etc. Such a high-density woven fabric has a single yarn density of 15,000 yarns/parallel inch or more, preferably 30,000 yarns/parallel inch or more. Here, the single yarn density is a value expressed as: Number of warp threads/inch x number of weft threads/inch + number of warp filaments x number of weft filaments (x number of divided segments). Fabrics outside this range, that is, fabrics with a single yarn fineness of 1
Over denier, single yarn density per square inch
With less than 15,000 pieces of fabric, it is difficult to obtain a good feel even if the coating resin is treated to prevent penetration, and even if it is obtained, good adhesive strength cannot be obtained at the same time. In the present invention, a polymer mainly composed of polyurethane resin is used as the coating resin. Examples of the polyurethane resin include commonly used polyester-based or polyether-based polyurethane resins, and special polyamide-based or polycarbonate-based polyurethane resins. are available, but 100% of these resins are effective in preventing hardening of the texture.
% modulus (during dry film creation) is 100
It is desirable that it is less than Kg/ cm2 . Further, other resins such as acrylic resin, silicone resin, and fluorine resin may be used in combination with these polyurethane resins. Such polyurethane resin is formed on at least one side of the high-density fabric by a dry method, a wet method, a lamination method, etc., and there are two types: porous ones with micropores on the film surface and non-porous ones. However, in order to obtain sufficient water resistance, the film thickness must be at least 10 μm, especially for non-porous films.
m, in the case of a porous film, a soft texture can be obtained when the thickness is 10 to 50 μm. This polyurethane resin film conforms to JIS K-6328
It is bonded to a high-density fabric with an adhesive strength of 0.9Kg/cm or more as specified in the above, and the water pressure resistance of such coating fabric is 700mmH 2 O or more (JIS L-1092), usually 700 to 5000mmH 2 Indicates the value of O. or,
If a porous film is used, the moisture permeability is 2000 to 8500g/
m2・24hr (JIS L-1099). The above coated fabric can be obtained by the following method. That is, first, using a melt-splitting composite fiber whose single fiber fineness after splitting is 1 denier or less, the single fiber density is
Weave high-density fabrics with more than 15,000 pieces per square inch. Composite fibers include a combination of polyamide or polyester and a polyester made by copolymerizing a third component such as isophthalic acid or polyethylene glycol to make it easily soluble in alkali. It is preferable that one component does not completely surround the other component in the cross section, and the fibers are joined along the longitudinal direction of a single filament. Specifically, composite fibers with a side-by-side cross section, side-by-side composite fibers, etc. A repeating composite fiber, a composite fiber consisting of a component having a radial shape and another component having a shape that complements the radiating portion, a component having a radial shape and a component that complements the radiating portion and is directed toward the center. Composite fibers made of the same component as the other component having a V-shaped concave shape and the component having a radial shape having a V-shaped shape that complements the concave portion, and a side-by-side repeating type having a hollow portion. Examples include composite fibers. Among these conjugate fibers, conjugate fibers having a component whose cross section has a radial shape are preferred. Such textiles are produced by fibrillating the dissolvable split composite fibers, and when a component easily soluble in alkali is used in the fibrillation treatment, a method of dissolving and removing the component with an alkaline solution such as sodium hydroxide can be used. In the present invention, in order to obtain a coating fabric that is highly durable and has a good texture, the high-density fabric is thermally calendered to increase the penetration of the coating resin by 1/4 to 1/2 of the thickness of the fabric. is controlled. The conditions for thermal calendaring are a temperature of 120 to 190
℃, preferably 130~170℃, linear pressure 50~500Kg/cm,
The preferred range is 80 to 300 kg/cm. If the temperature is less than 120℃ or the linear pressure is less than 50Kg/cm, smoothing will be insufficient and the texture will harden due to penetration.
Under conditions where the linear pressure exceeds cm, there is a risk that the texture will harden and the adhesive strength will decrease due to fiber fusion. Conditions for the thermal calendaring treatment are appropriately selected from the above range depending on the fibers constituting the fabric. In the present invention, the polyurethane resin is coated on the high-density fabric to form a resin layer having a thickness of 10 μm or more. The coating method for the polymer may be a dry method, a wet method, or a solvent-free method, and may be a floating knife coater, a knife over roll coater, a reverse roll coater, a roll doctor coater, a gravure roll coater, a kiss roll coater. Other coating methods can be used. Lamination processing can also be used, but the adhesive should be one that provides sufficient adhesion and is less likely to harden the texture. Furthermore, in order to obtain a soft texture, it is desirable that the viscosity of the coating liquid is 10,000 cps or more; if it is less than 10,000 cps, the penetration of the coating resin will be more than 1/2 of the fabric thickness, which may harden the texture. be. In the present invention, it is also possible to perform water-repellent finishing using a fluorine-based water repellent or a fluorine-based water repellent containing a silicone-based water repellent before thermal calendering. In this case, penetration of the coating resin is further reduced, resulting in a softer texture.
However, in order to maintain adhesive strength, it is preferable to use the silicone water repellent in an amount of 20% by weight or less based on the soft water repellent. (Example) Example 1 Warp yarn is 70 denier 36 filaments, weft yarn is 100 denier 50 filament, warp yarn density is 110/inch, weft yarn density is 84 yarn/inch, warp is nylon 6 filament, weft is 8 pieces extending radially. Taffeta, which is a fibrillated composite filament made of 6 nylon components and complementary polyethylene glycol copolymerized polyethylene terephthalate, is processed to reduce its weight with a caustic soda aqueous solution, and the polyethylene glycol copolymerized polyethylene terephthalate component in the weft is dissolved and removed. Single yarn denier approx.
A high-density fabric having a denier of 0.18 and a single yarn density of approximately 37,560 pieces/inch 2 was obtained. Subsequently, after dyeing and drying using a jet dyeing machine, water repellency treatment was performed by padding with a 2% aqueous solution of a futsuo-based water repellent. Then temperature 160
Thermal calender treatment was performed under the conditions of ℃ and linear pressure of 130 kg/cm to smooth the surface. Furthermore, a polyurethane resin solution with the following formulation was applied immediately using a roll doctor coater.
Wet coagulation was performed in water at 30°C, followed by hot water washing at approximately 40°C. Polyester polyurethane resin 30 parts Blocked isocyanate 3 parts N,N-dimethylformamide 100 parts Next, padding with a 1% aqueous solution of silicone water repellent and drying at a temperature of about 120°C.

The adhesive strength was good at about 1.6 to 2.0 kg/cm, and the texture was extremely soft. Comparison row 1 All the same steps as in Example 1 were carried out except that the thermal calender treatment was omitted. In this coated fabric, the film thickness was approximately 25 μm, and the penetration of the resin into the fabric exceeded 1/2 of the fabric thickness, and some resin leakage was observed on the back side. In addition, the texture was paper-like and somewhat hard. Comparative Example 2 A woven fabric made of refined nylon 6 taffeta with a warp of 70 denier and 18 filaments, a weft of 70 denier and 18 filaments, and a warp density of 112 threads/inch and a weft density of 90 threads/inch, that is, a single thread denier of approximately 3.9 denier.
For a fabric with a single yarn density of approximately 3640 threads/inch 2 ,
The steps after dyeing in Example 1 were carried out. The obtained coating fabric has a film thickness of approximately 25 μm,
The penetration of the resin into the fabric was 1/4 to 1/2 of the fabric thickness, but the texture was paper-like and hard, and the adhesive strength was slightly inferior at 0.6 to 0.8 kg/cm.
