いる。2. Description of the Related Art Since the polymer matrix used for polyamide fibers is inherently transparent, knitted fabrics knitted with synthetic fibers composed only of a polymer and dyed in a light color system generally have the disadvantage that the material behind the fabric can be seen through. Also, nitric oxide compounds in the atmosphere, vanillin which is a decomposition product of glycine contained in cardboard, BHT contained in packaging materials, etc.
And the like. It is said that the amino group at the terminal of the molecular structure of the fiber is involved.

った。In order to make up for this drawback, for example, in the case of sewing specifications for swimwear, the entire surface is double-tailored, or a specific portion is dyed in the same color as the skin color for the lining,
Partial double tailoring was performed. In addition, the weight of the fabric can be increased, the thickness can be increased, and the elasticity can be reduced.However, the thickness, weight, and insufficient stretch of the fabric may hinder the movement of the body. There is a problem that the quality and aesthetics are reduced and the cost is increased.

アップが避けられないものであった。Further, as a method of improving the sheer-proofing property by improving the fabric, a method of disposing a yarn dyed in gray on the back side of a white fabric has been proposed in Japanese Patent Application Laid-Open No. 3-45791. This method is effective in preventing see-through, but has a problem in aesthetics because the back side is gray and the white-colored fabric surface tends to be dull. Further, since at least two kinds of yarns are required, complexity and cost increase in the fabric production stage are inevitable.

うという問題点があった。[0005] In addition, since polyamide fibers have a drawback of yellowing, there has been a problem to be solved such that a hue change occurs from yellowing when developed in white, light color, or the like. In other words, especially in the case of developing a white color or a light color that requires anti-transparency, the yellowing prevention performance is also required. As means for solving the drawbacks of the polyamide-based fiber, various proposals have conventionally been made as a method for imparting yellowing resistance to a polyamide-based fiber structure. For example, a method for reducing the amount of amino groups by mixing an acid anhydride during spinning is disclosed in Japanese Patent Application Laid-Open No. 1-229810, but the problem is that spinnability becomes poor or dyeability deteriorates. There was a point.

Although it is known, depending on the processing method, there has been a problem that the yellowing resistance is not always sufficient and the durability is poor.

繊維構造物を作ることができる。In the present invention, a polyamide fiber of a core-sheath type composite fiber containing a white pigment in at least a core portion is used. The white pigment used for the core is not particularly limited, but at least one or two or more white pigments selected from titanium oxide, zinc oxide, aluminum oxide, zirconium oxide, calcium oxide, magnesium oxide and the like are used. In particular, titanium oxide and zinc white are preferred, and a polyamide fiber structure having excellent sheer-proofing property, coloring property, and yellowing prevention property can be produced.

A loading of 5% by weight is preferred. When the content of the white pigment is in the above-mentioned range, a good sheer-proof property tends to be easily obtained in the fibrous structure, and the deterioration of the yarn-making property in the production of raw yarn is also easily prevented. Further, it is excellent in coloring property and yellowing prevention property when dyed in a light color.

A case in which a hue change that can be visually confirmed is likely to occur. When the L * value of the fiber structure is 40 or less due to dyeing or the like, even if the vanillin yellowing degree ΔYI is 5 or more, the degree of hue change due to yellowing is low. Generally, when a fiber structure having an L * value of 40 or more undergoes yellowing, the hue change is large, exceeding the allowable range as a product. That is, they have found that the L * value is 40 or more, and the occurrence of yellowing due to vanillin can be avoided as much as possible.

で評価した。In the present invention, various properties of the anti-yellowing fiber structure were measured by the following methods. A. Yellowing degree due to vanillin: (1) A cloth is immersed in a 0.5% by weight vanillin / ethanol solution for 15 seconds, excess liquid is removed between filter papers, air-dried, and then subjected to a dry heat treatment at 150 ° C. for 3 minutes. (2) The degree of yellowing (JIS-K7103) of the fabric before and after the above treatment was measured, and the degree of yellowing ΔYI was determined by the following equation. ΔYI = YI (after processing) −YI (before processing) (3) The yellowing degree was measured with a multi-source spectrophotometer CM-3600 (manufactured by Minolta Co., Ltd.), C light source, visual field 2 °, measurement diameter 25. 4m
m, UV light 400 nm or less was set and measured. B. Washing fastness: Measured according to the measurement method of JISL0844. C. Transfer dyeing fastness: Measured according to the measurement method of JIS L0846. D. Sheer-proof property: Sheer-proof property was evaluated by a wearing test by 10 women.
