2. Description of the Related Art Parasols should be protected from direct sunlight and should be kept cool.
It's there to prevent UV rays and prevent sunburn,
Most parasols used for women are relatively rough woven fabrics, and the fiber materials are mainly natural materials such as cotton and hemp, and are used exclusively for parasols. In recent years, products with enhanced ultraviolet ray shielding characteristics have become popular in parasols. It is common to apply a drug that absorbs ultraviolet rays to the base cloth, or pre-encapsulate components that absorb ultraviolet light into the fibers that make up the base cloth. By the way, the concept of parasols for women is generally used, but recently, the utility value of parasols for various purposes is being reassessed in many cases. For example, a golf umbrella has not only a function as a rain umbrella but also a reusable value as a parasol during golf play in summer. The number of golfers who want to prevent heat in the hot summer and reduce fatigue and prevent unnecessary sunburn is increasing. However, at present, it is difficult to obtain a parasol that satisfies both the function of blocking ultraviolet rays and blocking heat and the waterproofness of a rain umbrella.

As a parasol, it is difficult to satisfy all three of the function of blocking ultraviolet rays and blocking heat and the waterproofness of a rain umbrella. For example, if this is to be carried out by coating, it is necessary to add a large amount of inorganic particles to the coating film, which causes problems in the strength of the film and dispersibility of the inorganic particles, which impairs the appearance of the coating film and reduces The product is not well made. On the other hand, it is possible to request the fiber to have a function of blocking ultraviolet rays and blocking heat. That is, by kneading inorganic particles such as titanium oxide into synthetic fibers such as polyester at the time of spinning, the fibers themselves are given the ability to absorb ultraviolet rays and reflect heat rays, and thus have a function of blocking ultraviolet rays and blocking heat. be able to. By making a woven fabric using such fibers and applying a waterproof coating on one side of the woven fabric after dyeing, the desired parasol and rain umbrella can be obtained. However, when the fiber is polyester, dyeing is performed with a disperse dye, and thus there is a concern that the dye may bleed. In particular, when coating is performed, the concern increases because the coating resin and the disperse dye have good affinity. If the dye bleeds, color pollution will occur in the product umbrella (these two-tone colors of light color and dark color are common these days) and the value of the product will be lost. Thus, the current technology has some problems.

That is, according to the present invention, a polymer containing at least 8% by weight of at least one selected from the group consisting of titanium oxide, zinc oxide, talc and alumina is used as a core component, and a cation dyeable polymer is used. A base fabric for an umbrella, characterized in that at least a part of a fabric composed of a core-sheath type composite fiber having a weight ratio of the core component of 30% to 50% as a sheath component is made of water-soluble polyester. is there.

In the present invention, the core portion of the core-sheath structure contains inorganic particles which absorb ultraviolet rays and reflect heat rays, because such inorganic particles have a sharp color of dyed fibers. This is because it is impaired, so it is preferable to enclose it in the core rather than being present in the sheath. Titanium oxide, zinc oxide, talc, alumina and the like are preferable as the inorganic particles that absorb ultraviolet rays and reflect heat rays. The amount thereof is preferably 8% by weight or more, and more preferably 20% by weight or less, based on the fiber weight (including inorganic particles) of the core.
These inorganic particles may be used alone or in combination of two or more. The ratio of the fibers of the core portion to the whole fibers is preferably 30% or more and 50% or less. UV if less than 30%,
The heat ray shielding effect is reduced. If it exceeds 50%, it becomes difficult to stably cover the core with the sheath. Further, the polymer constituting the core component is not particularly limited, such as polyester, polyamide, polyolefin, and elastomer, but polyester is preferable.

Next, the fiber is also made of a cationic dyeable polyester so that it can be dyed with a bleed-free cationic dye, but at least the sheath must be a cationic dyeable polyester. The core does not necessarily have to be cationic dyeable polyester. This fiber is dyed with a cationic dye, but may be dyed in the coexistence of a disperse dye and a cationic dye. However, in this case, the amount of the disperse dye used must be limited to an amount that does not substantially affect bleed. Dyeing in the coexistence of a disperse dye and a cationic dye is advantageous in terms of cost and has an advantage that a dark color is easily obtained.

The dyed fabric is then waterproofed. The coating resin includes acrylic resin, urethane resin, acryl urethane resin, acryl silicone resin, amino acryl resin, amino urethane resin and the like. In, the type of resin is not limited. Any formulation may be used as long as it is waterproof as a rain umbrella. The umbrella manufactured using the woven fabric thus obtained has a function of blocking ultraviolet rays and blocking heat as a parasol, has excellent waterproofness as a rain umbrella, and has no problem due to bleeding of dye.
