[Technical Field of the Present Invention] The present invention relates to a composite spun yarn for clothing made of filament fibers and staple fibers. More specifically, the filament is made of highly oriented polyester filament that has been spun at ultra-high speed and has a low boiling water shrinkage rate.
Moreover, it relates to a specific composite spun yarn using this as a core. [Prior art and its problems] Conventionally, yarns used for knitting and fabrics include spun yarns or yarns made of continuous filaments. For the former, yarns that are soft, elastic, and taut, and yarns with a two-layer structure that have excellent covering properties have been proposed, but they are not perfect. Furthermore, the latter has been given added value such as improved sliminess and elasticity, which are unique to synthetic fibers, through shrinkage processing, etc. However, the disadvantages of fabrics are that they are transparent, have poor snag resistance, and cause grittiness. Furthermore, it has the disadvantage that the texture is still inadequate. Many so-called composite yarns, which are a combination of continuous filaments and spun yarns or short fibers, have been proposed as a means to compensate for these drawbacks.
A typical example is core yarn, which can be improved in terms of strength and uniformity by compounding, but because it has a yarn structure in which these two components are arranged alternately, it is possible to express the texture of spun yarn on the surface of the fabric, making it continuous. It is difficult to realize the performance of long fibers internally. In addition, in a composite yarn consisting of filament fibers and staple fibers, when ordinary drawn yarn is used for the filament fibers and cotton is used for the staple fibers, the boiling water shrinkage rate or heat shrinkage stress is higher than that of cotton fibers. The disadvantages are that the two tend to separate easily, and especially when polyester filaments are used, the Young's modulus of the filaments is too high and the excellent flexibility of cotton fibers is lost. In order to solve this drawback,
Japanese Patent Application No. 69340 proposes that a normally drawn synthetic fiber and a cotton fiber are combined and twisted and then heat treated under tension while being wound around a bobbin to eliminate residual shrinkage of the synthetic fiber. However, even in this case, a twisting process and a heat treatment process are essential, and the problem of the high Young's modulus of polyester has not been solved at all. The known technique closest to the present invention is JP-A-58-109648, which was proposed by the inventors of the present invention. The morphological stability and other aspects were still unsatisfied, and further improvements were desired. [Purpose of the present invention] The present invention is intended to solve the above-mentioned drawbacks, and the purpose is to express the characteristics of short fibers on the yarn surface, and to create a continuous layer inside the yarn that is compatible with the short fibers. The objective is to provide a composite yarn that is made of long fibers and is soft, yet has plenty of tension and stiffness. [Structure of the present invention] The present invention consists of the following structure. That is, the core-sheath composite spun yarn of the present invention is a real twisted core-sheath composite spun yarn consisting of filament fibers and staple fibers, in which the filament fibers are polyester filaments in which 90 mol% or more is composed of ethylene terephthalate units. Young's modulus 40 to 105 (g/d), filament yarn density ρ = 1.365 g/cm 3 or more, birefringence △n =
0.08 or more, and a boiling water shrinkage rate ΔS of 8% or less constitutes a multifilament, and the filament fibers are arranged in a core part, and the staple fibers are arranged in a sheath part. It is a composite spun yarn with a core-sheath structure. The core-sheath structure composite spun yarn of the present invention is shown in FIGS. 1 and 2. FIG. 1 is a side view, and FIG. 2 is a cross-sectional view. In FIGS. 1 and 2, 13 is a polyester filament, and 14 is a staple fiber, which is arranged in the sheath. The filament 13 is placed in the core of the composite yarn, and the entire composite yarn is actually twisted. That is, not only the staple fibers 14 but also the filament fibers 13 are actually twisted. Therefore, it is preferable that the twist angles of the substantially outermost layer portion of the filament fiber 13 and the substantially innermost layer portion of the staple fiber 14, that is, the boundary portion between both fiber layers, are substantially equal for both fibers. The reason for this is that when the twist angles are equal, separation of both fiber layers is prevented. The filament fibers may be raw silk, false twisted yarns, other crimped yarns, or even those having entanglements or loops. Next, in the present invention, it is necessary that the main component of the polyester filament is 90 mol% or more of ethylene terephthalate units. Strength,
This is based on overall quality characteristics such as texture, tension, elasticity, dyeability, and wrinkle resistance. Further, the polyester filament needs to have a Young's modulus of 40 to 105 g/d. This is to make the texture of the composite yarn soft.
If the Young's modulus exceeds 105 (g/d), the composite yarn will not only become hard, but also have poor twisting properties during spinning, which is not preferable. Further, a yarn having a Young's modulus of less than 40 (g/d) is not preferable because it lacks stiffness and the strength of the composite yarn decreases. In addition, the filament fiber has a filament yarn density ρ=1.365
g/cm 3 or more, birefringence Δn=0.08 or more, and boiling water shrinkage rate ΔS=8% or less. In order to obtain the filament fiber of the present invention, the take-up speed during melt spinning is preferably 4500 m/min or more, preferably 5000 m/min or more. Further, when the spinning speed is 3500 m/min or more, it can also be obtained by heat treatment using dry heat or wet heat during the spinning process. On the other hand, the staple fiber is not limited in any way as long as it can be subjected to a normal spinning process. For example, any synthetic fiber such as polyester or polyamide, natural fiber, etc. may be used. Particularly in the present invention, it is preferable that all or part of the staple short fibers contain cotton, since water absorption ability can be imparted to the composite yarn. To obtain the composite yarn of the present invention, V(B)>V(A) (V(A): feed rate of continuous filaments, V( B): Feeding speed of short fibers) This can be easily achieved by feeding the short fibers at the following speed relationship. The speed difference is
It is good to set it as 1.01-1.20V(A)=V(B), preferably 1.03-1.10V(A)=V(B). The yarn convergence means is based on actual twist, and the twist coefficient is as good as that of ordinary spun yarn, but it is desirable to adopt a higher twist coefficient in order to improve coverage. To explain an example of the manufacturing method in more detail with reference to the drawings, FIG. 1 shows an embodiment for obtaining the composite yarn of the present invention.
is provided to the bag crawler 2, passes through the apron roller 3, and is sent out as a fleece 5 from the front roller 4. On the other hand, the filament fiber 6 is supplied to a supply roller 8 via a tension adjustment device 7, and then provided to the front roller 4. At this time, the top roller 4' of the front roller 4 is provided from the circumference side of the stepped small diameter portion. By doing so, the distance between the two components can be shortened, and the combination and focusing can be performed smoothly. The distance between the two components during twisting is preferably about 2 to 10 mm. The convergence means is based on a real twist, and the composite yarn 9 of the present invention is wound onto the winding bobbin 1 through a snail guide 10 and a traveler 11.
Wind it up to 2. In this invention, the yarn structure is determined by the fleece 5 fed out from the front roller 4.
and the speed of the supply roller 8 of the filament fiber 6, and the speed of the fleece 5 V(B),
If the velocity of filament fiber is V(A), then V(B)＞
V(A). Preferably, the rotation of the front roller 4 and the rotation of the supply roller 8 are synchronized with each other. [Effects of the present invention] The composite yarn of the present invention has no boundary distance between filament fibers and staple fibers, is strongly integrated, and has excellent pilling resistance. The reason for this is that the twist angles near the boundary between the two components are approximately equal, and the filament fiber has a low Young's modulus, so it has excellent twistability. Furthermore, since the shrinkage rate of the filament fiber is small, the two components do not separate even when dyed, ironed, etc., and the shape stabilization effect is large. In addition, the yarn as a whole is soft and has an excellent texture. This will be explained in further detail in Examples below. Example 1 Filament fiber made of polyethylene terephthalate, yarn density 1.371 g/cm 3 , birefringence Δn=
0.105, Young's modulus 80g/d, boiling water shrinkage rate 3.0% (98
A composite yarn was obtained by the method shown in FIG. 3 using 50D-24fi1 (after processing for 20 minutes at C) and using cotton mainly composed of rice cotton SJV as the staple fiber. Part 2
The feed rate relationship for the combination of components is V(B) = 1.06V(A)
(However, V(B) is the supply speed of the staple fiber bundle, V
(A) is the filament feeding speed), and the twist coefficient K
= 3.5 (T = K√: T is the number of twists per inch, K is the twist coefficient, and Nec is the English count), and Nec = 36s was spun. The obtained composite yarn is the first
As shown in Figures 2 and 2, it had excellent covering properties. The composite yarn was subjected to a 28G circular knitting machine to obtain a jersey knitted fabric. Next, after dyeing and finishing,
The surface of the resulting knitted fabric exhibits the quality and feel of 100% cotton, the characteristics of cotton can be utilized as is, and the fabric has good dimensional stability. The practical performance of the fabric is as follows. Furthermore, in the above, as the polyester multifilament yarn, Toray
Regular type (Young's modulus 110g/d) 50D manufactured by Co., Ltd.
A fabric was produced in exactly the same manner except that −24fil yarn was used, and the practical performance of the fabric was compared (comparison product).
