DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method for producing heavy fabrics that can be used outdoors and have excellent light resistance and chemical resistance.

(b) Conventional technology Synthetic fibers have traditionally been widely used in heavy fabrics used outdoors, such as ship covers, tents, life preservers, vehicle seats, hoods, covers, construction sheets, civil engineering sheets, and open pile sheets. Recently, fabrics (base fabrics) made of filament yarns or spun yarns of polyamide, polyester, vinylon, etc. are impregnated or coated with polyvinyl chloride resin, polyacrylic acid resin, or polyurethane resin. This gives it water resistance, light resistance, and chemical resistance.

is frequently used. However, these heavy cloths are
Due to long-term outdoor use, strength loss, discoloration, etc. are observed, and various weather resistance is not necessarily sufficient.This not only causes deterioration of the resin coating on the surface of the base fabric, but also deterioration of the fiber material of the base fabric. This means that its useful life is naturally limited. Furthermore, even if used for a short period of time without a decrease in strength, the plasticization of the resin on the surface is reduced, making it extremely easy for dirt to adhere, impairing the appearance and making it less comfortable to use. Furthermore, chemical resistance, which is an important property depending on the application, is not always fully satisfactory.

Generally, when heavy fabrics are used outdoors, they are naturally often exposed outdoors for long periods of time, but they are required to maintain at least 80% of their initial performance even if strength decreases or discoloration occurs due to outdoor use. This has led to the emergence of heavy fabrics that meet these performance requirements.

On the other hand, among general synthetic resins, polyvinyl fluoride resin is known as one of the ones with excellent weather resistance and chemical resistance.It forms a tough film and is extremely stable at temperatures up to 100℃.
Some of the following are not soluble in ordinary solvents and are used as films or paints. However, even if the polyvinyl fluoride resin is simply applied to the fiber base fabric,
It has a very hard texture, making it impossible to obtain a material that can be put to practical use, and there are also problems in processing, such as requiring an extremely long heat treatment to form a resin film.

First, the base fabric is pre-treated with a fluorine-based or silicon-based water repellent. Through this water repellent pre-treatment, a film of the water repellent is formed on the base fabric, and the next step is polyfluorination. Treatment with a solution containing vinyl resin as the main component prevents the solution from penetrating deeply into the tissue of the base fabric, and creates a texture by forming a film of polyvinyl fluoride resin near the fiber intersection points. can prevent hardening. As the water repellent, a commercially available water repellent made of an organic fluorine compound or an organosilicon compound can be used. A solution or dispersion of the water repellent is applied by a conventional band method, and after drying, curing is performed. I do. The water repellent is added to the base fabric in a solid content of 0005 to F weight%,
If it is less than 0.05% by weight, the water repellent treatment effect will be insufficient and the final product will only have a hard texture, and if it is more than 1% by weight, the polyfluorinated vinyl resin formed in the next step will It is unsuitable because the adhesion between the coating and the base fabric is severely damaged and problems such as peeling are likely to occur.

Next, the base fabric pretreated with a water repellent as described above is treated with a solution containing mainly a polyvinyl fluoride resin and at least a curing agent, a curing catalyst, an aluminum foil fine powder, and an organic acid salt of a specific metal. A coating mainly composed of polyvinyl fluoride resin is formed on the surface, thereby dramatically improving light resistance and chemical resistance. As the polyvinyl fluoride resin, a vinyl fluoride homopolymer or copolymer soluble in an organic solvent is used. The curing agent has the function of promoting the formation and curing of the polyvinyl fluoride resin film on the surface of the base fabric, and uses methylol melamine compounds such as methylated methylol melamine and butylated methylol melamine, or diisocyanate, etc. To accelerate the curing reaction of the curing agent, magnesium chloride, zinc nitrate, and phosphate are used as catalysts.

The solution mainly containing polyvinyl fluoride resin contains 20 to 50% by weight of polyvinyl fluoride resin, 3 to 10% by weight of curing agent, 0.1 to 2% by weight of curing catalyst, and 3% by weight of aluminum foil fine powder. Most favorable results are obtained with a concentration of ~10% by weight and 5-10% by weight of the organometallic salt. In the treatment with the solution, it is necessary to apply the solution to one or both sides of the base fabric by a conventional pad method or coating method in a solid content range of 5 to 50 g/rrf.
