に生じてくる。(Prior art) Conventionally, -C acrylic fibers have been used to make wool into Ilj! (It has a sublime texture, excellent physical properties, solid dyeability and color clarity, and is used in a wide range of applications.However, acrylic fibers are similar to most natural fibers and synthetic fibers. Because it is easily flammable, its demand range has been narrowed, as it aids the spread of fire in applications such as clothing, interior products, and industrial and architectural applications.On the other hand, flame-retardant acrylic fibers are difficult to Although it has flammability and self-extinguishing properties,
The performance of the products, such as stiffness, bulkiness, and stiffness, is not as good as that of ordinary acrylic fibers, and they are not yet used in sufficient quantity.Therefore, flame-retardant acrylic fiber products are being developed to improve the above-mentioned drawbacks. As a method, it is generally done to blend other fibers with excellent physical properties, such as nylon, polyester, and polyacrylonitrile fibers, but blending increases processing steps, reduces dyeability, and changes in texture. , new disadvantages such as a decrease in flame retardancy arise.

まだ満足されるものでなかった。In order to improve the bulkiness, stiffness, stiffness, etc. of products made from flame-retardant acrylic fibers, shrink cotton with equivalent flame retardancy and fibers with latent crimp properties are required, especially the latter. By using a mixture of this flame-retardant acrylic fiber with latent crimp properties and ordinary flame-retardant acrylic fiber, it has flame retardancy and has good elasticity, bulkiness, texture, dyeability, etc. It becomes possible to manufacture products. However, the potential has been good so far! ! Flame-retardant acrylic composite fibers that have both shrinkability and flame retardancy have not been obtained, nor have they been studied much. JP-A-49-68014 discloses a composite fiber of a polyacrylonitrile polymer containing 85% or more of acrylonitrile, a flame-retardant acrylic polymer, and a halogenated antimony compound. Since the fiber uses polyacrylonitrile polymer as one component, flame retardancy cannot be sufficiently increased.In order to increase flame retardance, the content of vinyl chloride and antimony halide in other components must be adjusted. As it increases, the miscibility between image components increases.
Differences in compatibility can cause gelation in the spinneret, clogging of the spinneret, and thread breakage, and since the coagulation properties of the two components are significantly different, it is difficult to set coagulation bath conditions that will coagulate both components densely. It is Noh. Furthermore, even after spinning, due to insufficient adhesive strength between the image components, it is expected that problems will occur due to peeling of both components during stretching, shrinkage, etc., resulting in a drastic decrease in operability and quality. In addition, it is expected that the product will suffer from a decline in consumer performance such as dyeability, heat resistance, and gloss, as well as a decline in processing performance such as thread breakage and fluff during spinning and milling. Japanese Patent Publication No. 59-8241
Publication No. 0 is a composite fiber made by adding and spinning a polyurethane polymer to a flame-retardant acrylic polymer, but the fiber obtained here not only increases the cost of the fiber due to the added polyurethane polymer, but also However, the coloring properties and light fastness of these materials were still unsatisfactory.
