The present invention relates to a spun yarn that provides excellent linen feel to woven or knitted fabrics through appropriate heat treatment. Generally, it is well known that fibers with a high melting point are mixed with low melting point fibers and heat treated to melt the low melting point fibers to produce a spun yarn with a linen-like texture, and many proposals have been made in the past. is being done. For example, two or more types of thermoplastic synthetic fibers with different melting temperatures are fused together while being twisted.
-14586), some of the fibers are heated and fused using a hot plate while drawing two or more types of fibers with different melting points (JP-A-52-96254), and the blending ratio of low melting point components is 3 to 15% by weight. The fusion rate is 0.4~0.02 with spun yarn with %
% by weight (Japanese Patent Application Laid-open No. 50-4000), untwisted spun yarn made by subjecting a fiber bundle containing low-melting point fibers to a false twist heat treatment and fusing the low-melting point fibers (Japanese Patent Application Laid-Open No. 48-9052); Open-end spun yarn containing 5 to 20% by weight of low-melting point fibers and fused to high-melting point fibers (Japanese Patent Laid-Open No. 54
No. 3444, when combining several spun yarns, a low melting point synthetic filament or spun yarn is placed in the center and heat treated.
The fabric is made of a mixture of 10 to 20% of heat-resistant synthetic fibers and fibers with a melting point about 50°C lower than the synthetic fibers, which are bonded to each other on the inner surface in contact with the core yarn (Japanese Patent Application Laid-Open No. 158340/1983). Adhesive
69202). However, in these conventional techniques, the strength of the low-melting point fiber itself is weak, resulting in significant damage to the fiber during the spinning process, fiber waste is generated in carding machines and spinning machines, and the adhesive strength as a binder is lacking. The strength of the spun yarn was low, and the unique texture of linen had difficulty in being durable against repeated bending, so it was not possible to obtain a sufficient spun yarn with a linen-like texture. As a result of intensive research by the present inventors in order to eliminate the drawbacks of the conventional technology, the use of core-sheath type low melting point composite polyester fibers has improved adhesive strength and strength, and has improved the woven fabric after heat treatment. The present inventors have discovered that a spun yarn that provides an excellent linen-like texture to knitted fabrics can be obtained, and have completed the present invention. That is, the present invention is a mixed spun yarn consisting of two types of polyester fibers A and B, in which fiber A is a polyester fiber with a normal melting point, and fiber B is a polyester component with a normal melting point in the core and a melting point in the sheath.
It is a core-sheath type composite polyester fiber composed of a polyester component with a low melting point of 150 to 200°C, and is a polyester spun yarn characterized in that the blending ratio of fiber B is 10 to 90% by weight. The polyester with a normal melting point as used in the present invention mainly refers to polyethylene terephthalate, but also includes copolymerized polyesters having copolymerized components in addition to terephthalic acid and ethylene glycol as long as the melting point is 220° C. or higher. Moreover, the low melting point polyester refers to a copolymerized polyester of one or more dibasic acids or derivatives thereof and one or more glycols. That is, examples of dibasic acids include aromatic dibasic acids such as terephthalic acid, isophthalic acid, phthalic acid, P-oxybenzoic acid, 5-sodium sulfoisophthalic acid, naphthalene dicarboxylic acid, oxalic acid, adipic acid, sebacic acid, Examples include alicyclic dibasic acids such as azelaic acid and dodecanedicarboxylic acid. On the other hand, examples of glycol include ethylene glycol, diethylene glycol, triethylene glycol, propanediol, butanediol, pentanediol, hexanediol, neopentyl glycol, P-xylycylene glycol, and the like. As a preferred example of the combination of these dibasic acids and glycols, the glycol component uses 85 mol% or more of ethylene glycol and less than 15 mol% of diethylene glycol, and the dibasic acid component uses 70 to 90 mol% of terephthalate. A copolymerized polyester consisting of a combination of an acid and one to three dibasic acids selected from phthalic acid, isophthalic acid, and adipic acid is suitable. As mentioned above, spun yarns made by mixing low-melting point polyester fibers with ordinary polyester fibers, or woven or knitted fabrics obtained from the same, can be heat-treated to melt the low-melting point components, resulting in a hemp-like texture.
The low-melting point polyester fibers melt and adhere ordinary polyester fibers to each other, reducing the elasticity and bending recovery of the yarn, and at the same time disrupting the parallelism of the yarn surface, creating a smooth and cool feel for linen fabrics. This is because it resembles knitting. However, molten polyester is inherently very rigid and tends to come off the adhesive after repeated bending, making it difficult to maintain the above-mentioned linen-like texture. On the other hand, since the polyester spun yarn of the present invention is a mixture of core-sheath type low melting point cotton, firstly, the adhesive surface is large, and secondly, the rigidity of the melted part is relaxed.
The strength of the spun yarn is extremely strong by maintaining the linen-like performance with a crisp and cool feel against repeated bending, and thirdly, the polyester component in the core contributes to the strength of the spun yarn. It is high and maintains the robustness of linen's unique texture against repeated bending.
It is a spun yarn with an excellent hemp texture. In the core-sheath type composite polyester fiber of fiber B used in the polyester spun yarn of the present invention, it is appropriate that the proportion of the low melting point polyester component disposed in the sheath portion is 40 to 60% by weight of the total. When the proportion of low melting point polyester in the sheath is less than 40% by weight, the adhesion to the polyester fibers usually decreases, the elasticity and bending recovery of the spun yarn do not decrease, and the degree to which the parallelism of the yarn surface is disturbed becomes weaker. , a spun yarn with a hemp-like texture cannot be obtained. Furthermore, if the low melting point component exceeds 60% by weight, the proportion of the polyester component in the core decreases, which is undesirable because the strength utilization factor contributing to the spun yarn decreases. The melting point of the core-sheath type polyester fiber must be 150-200°C. If the melting point is below 150°C, the linen-like texture will be significantly lost due to heating during dyeing, etc. If it exceeds 200°C, the strength of polyester fibers will usually decrease when melted by heat treatment, impairing the performance of polyester fibers. cormorant. Further, the core-sheath type polyester fibers of the fiber B constituting the polyester spun yarn of the present invention can be used in a mixing ratio of 10 to 90% by weight, but preferably 20 to 70% by weight. . Mixing ratio is 10
If the amount is less than % by weight, adhesion to fiber A, that is, normal polyester fiber, will not be sufficient, and the texture will be far from linen-like. On the other hand, if it exceeds 90% by weight,
The spun yarn becomes too hard, the yarn becomes brittle, and the strong properties of polyester fibers are not utilized. The heat treatment for imparting linen-like texture to the polyester spun yarn of the present invention and the woven or knitted fabrics obtained therefrom is carried out at a temperature higher than the temperature at which the low melting point polyester component of the core-sheath type polyester fiber melts. It may be carried out at an appropriate temperature within the range below. Since the polyester spun yarn of the present invention uses core-sheath type composite polyester fiber as the low-melting point cotton,
It is possible to increase the mixing ratio up to 90% by weight, eliminating the generation of fiber waste (white powder) in card machines and spinning machines, which conventionally caused problems in the spinning process, and at the same time improving the strength and adhesion of spun yarn. It is possible to obtain a spun yarn having a stable, high-quality hemp-like texture. Examples will be explained below. Example 1 The mixing ratio of terephthalic acid and isophthalic acid was changed and copolymerization was carried out in a conventional manner, and the properties (melting point) were obtained as shown in Table 1.
Obtained different chips. Of these chips,
It is a special core-sheath type spinning device in which chips with a low melting point are arranged in the sheath part and chips with a normal melting point in the core part in a 1:1 ratio, and the spinning speed is 1000 using a 336-hole nozzle.
An undrawn yarn tow with a single yarn fineness of 15 d was obtained by spinning at a discharge rate of 490 g/min and a discharge rate of 490 g/min. The undrawn yarn tows were bundled so that the tow denier after drawing was 100,000 deniers, and the drawing temperature was 70°C using a normal method.
Stretching was carried out at a stretching ratio of 3.50 times to obtain a core-sheath type composite polyester cotton [fiber B] with a fineness of 4d. This cotton is blended with regular polyester fiber (40% elongation, brand 2D x 51mm) in a 1:1 ratio using a cotton blending machine, and then carded, drawn, roved, and spun into a 20'S spun yarn. I got it. The spun yarn has 103 warps/inch,
Woven with 87 wefts/inch and 93cm width,
Heat treatment was performed and the texture was examined. In addition, the single yarn tenacity of the spun yarn was measured by heat treating it in the skein state. The results are shown in Table 1.
