に関する。Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a yarn constituting a part of a woven or knitted fabric, which is made of atmospheric pressure dyeable polyester, is easy to handle, and has a novel appearance and feel. This invention relates to a polyester thick and thin yarn suitable for use as a polyester yarn.

The thicker parts of polyester threads are dyed darker than the thinner parts, so when they are made into woven or knitted fabrics, they exhibit a mottled pattern, which is one of the characteristics of polyester threads.

余儀なくされていた。One of the techniques to control this mottled pattern is to use copolymerized polyester to control the difference in shading between the thick and thin parts of thick and thin threads.
No. 5, JP-A-61-231220, JP-A-6
It is known from the publication No. 2-85024. These are cationically dyeable yarns using a dicarboxylic acid containing a sulfonic acid metal base such as 5-sodium sulfoisophthalic acid as the third copolymerization component. However, these copolymerized polyesters are significantly different from thick and thin yarns using homopolyesters in terms of strength and elongation, so their uses have been limited.

れている。On the other hand, regarding techniques for mixing polyester fibers and natural fibers, many techniques have been proposed for imparting high dyeability to polyester fibers to obtain the same color property as natural fibers. For example, cationic dye-dyable polyesters copolymerized with 5 mol% (8% by weight) or more of sodium sulfoisophthalic acid are JP-A-61-34022 and JP-A-6O-2411i8.

It is disclosed in various publications.

汚染が大きい等の問題がある。However, although cationic dye-dyeable polyester copolymerized with sodium sulfoisophthalic acid has improved dyeability, it has low yarn strength, lacks bulkiness, lacks a sense of fullness, poor heat resistance, and is difficult to process in bulk. There are problems such as practically no applicability, poor chemical resistance, poor light fastness of cationic dyes, and large contamination of dyeing machines with cationic dyes.

る。In addition, although easily dyeable polyester fibers produced by high-speed spinning have improved dyeability compared to conventional polyester fibers,
It cannot be said that it is completely dyeable under normal pressure, but to dye it in a deep color, 1
A dyeing temperature of 10 to 120°C is required, and the shrinkage rate of the raw yarn is low, so it lacks dimensional stability, lacks a tight texture, tends to have mesh misalignment, and is difficult to spin into fine yarn. There are some problems, such as the need for excessively large silk spinning equipment.

There are problems such as large yellowing and discoloration. Among aliphatic diols, polyesters copolymerized with butanediol, neopentyl glycol, cyclohexane dimetatool, polytetramethylene glycol, etc., isophthalic acid, 1.2-
For polyester copolymerized with aromatic dicarboxylic acids such as bis(phenoxy)ethane 4.4' dicarboxylic acid, the copolymerization rate must be 15% by weight or more to make it dyeable under normal pressure. There are problems such as a decrease in yarn strength, a decrease in light resistance, yellowing, and poor spinning properties.

After dyeing, the dyeing ability of the fiber is completely saturated, and even if there are slight changes in the dyeing conditions, such as when dyeing a large amount of material, the finished dyeing will be 98%.
This is because dyed products of the same quality as those dyed at °C can be produced, which is preferable. In addition, the dyeability of polyester thick and thin yarn differs between the thick and thin portions, but the normal pressure dyeable polyester thick and thin yarn in the present invention needs to have both the thick and thin portions dyeable. . In addition, L9g and Li2O

得られない。The normal pressure dyeable polyester thick and fine yarn of the present invention has thick and thin lines in the longitudinal direction of the yarn, and the degree of thick and thin unevenness must be in the range of 3 to 15% as measured by the U% value measuring method described below. There is. U
If the percentage value is less than 3%, the difference in shade due to dyeing will be small and it will be impossible to obtain a woven or knitted fabric having a crisp, kasuri-like texture, which is the object of the present invention. In addition, the normal pressure dyeable polyester thick and fine yarn of the present invention and natural fibers may be blended or combined,
When used in combination and twisting, it is preferable that the U% value is 5% or more because a woven or knitted fabric with a fluffy feel can be obtained. On the other hand, if the U% value exceeds 15%, the proportion of the thick portion becomes too large and the product value falls outside of the range that can be called a kasuri style, so that the woven or knitted fabric that is the object of the present invention cannot be obtained. do not have.

撚加工等の高次加工を施すことが可能となる。The feature of the pressure-dyeable polyester thick and thin yarn of the present invention is that although it is a large and thin yarn made of copolymerized polyester, its strength and elongation are similar to that of homopolyester. By making the strength and elongation similar to that of homopolyester, it becomes possible to perform high-order processing such as false twisting on thick and thin yarns.

ため得られたポリエステルの軟化点が低下し、最終的に
得られる製品の品位が低下する。The atmospheric pressure dyeable polyester used for the atmospheric pressure dyeable polyester thick and thin yarn of the present invention must be a copolymer of 6.0 to 10% by weight of polyethylene glycol having an average molecular weight of 500 to 3,000. When the average molecular weight is less than 500, a part of the polyethylene glycol added during polyester polymerization is dispersed under high temperature and reduced pressure reaction conditions, and the copolymerization rate of polyethylene glycol in the polyester is not constant, so the obtained polyester This causes variations in physical properties such as strength and elongation, shrinkage rate, etc. of thick and thin yarns, which worsens the passability of the process and causes defects in the final product. 50 again
In order to copolymerize polyethylene glycol with a low molecular weight of less than 0 to improve dyeability, it is necessary to increase the number of moles of copolymerization considerably compared to polyethylene glycol with a high molecular weight. The softening point decreases and the quality of the final product decreases.

堅牢度が低下するなど、種々の染色堅牢性の低下を引き
起こす。On the other hand, when polyethylene glycol with an average molecular weight exceeding 3000 is used, the dyeability not only decreases due to the increase in the high molecular weight that is not copolymerized in the polyester, but also the dye bleeds when the fabric is heat treated after dyeing. This causes various kinds of deterioration in color fastness, such as bleed-out and light fastness, especially in most of thick and thin yarns.

光堅牢性が低下し、最終製品が低下する。Further, if the copolymerization rate of polyethylene glycol is less than 6.0% by weight, dyeability is insufficient and normal pressure dyeability cannot be obtained. On the other hand, if it exceeds 10% by weight, the dyeability is so high that not only the desired texture cannot be obtained, but also the strength of the thick and thin yarn decreases, making it extremely difficult to pass through higher processing. Also, the light fastness is reduced and the final product deteriorates.

。The crunchy texture of the present invention varies slightly depending on the combination of the copolymerization amount of polyethylene glycol copolymerized with polyester and the U% value. This is presumed to be because both of them have a great influence on the dyeability of the normal pressure dyeable large fine polyester yarn. Specifically, the amount of polyethylene glycol copolymerized is 20 (wt%)
) and U% value: When the relational expression G+U/2≧9.5 is established, a crispy Kasuri-like texture is clearly expressed, which is preferable. When this relational expression is not satisfied, the dyeability is slightly insufficient and the texture is slightly inferior. Also, G+U≦21
If the following relational expression holds true, the smeared texture will be moderate, which is preferable. If this relational expression is not satisfied, the dyeing properties tend to be a little high, and the dull tone tends to be emphasized a little too much.
