Description

[Detailed explanation of the idea]

(Field of Industrial Application) The present invention relates to a spun-like fancy yarn that is bulky and has a spun-like texture and appearance. (Conventional technology) Conventionally, slub yarn obtained by twisting multifilament yarn in a design, slub yarn by spinning,
Fancy yarns such as net yarns or slub yarns obtained by air-treating multifilament yarns are known, and fancy yarns obtained by combining and twisting these fancy yarns with other yarns are also known. (Problems to be solved by the invention) However, the fancy yarns made of the multifilament yarns described above are not spun-like in texture and appearance, and all of the fancy yarns described above are inferior in bulkiness. The fancy yarn mentioned above consists of a thick part such as a slab part or a neck part and a thin part other than that, so it is easy to get caught at the boundary between the thick part and the thin part during weaving and weaving, and abnormal tension is likely to occur.
It has the disadvantage that unwinding, knitting, and weaving of the yarn is difficult, and furthermore, the yarn layer of the yarn package is easily destroyed. The purpose of this invention is to eliminate these drawbacks of conventional yarns, and the purpose is to have a spun-like texture and appearance with excellent bulkiness, as well as less snags during weaving and weaving. To provide a spun-like fancy yarn which has good knitting and weaving properties and further prevents the yarn layer of the yarn package from collapsing. (Means for Solving the Problems) In other words, the present invention provides a yarn having knots consisting of a thick portion formed by a larger concentration of fibers constituting the yarn than other portions, and a thin portion other than the thick portion. The gist of the invention is a spunlike fancy yarn in which a conventional multifilament yarn is entangled by fluid treatment, and loops are formed on the surface of the yarn at least in the thin portion. The present invention will be explained in detail below. First of all, the spunlike fancy yarn of the present invention is a yarn (hereinafter referred to as a yarn with knots) consisting of a thick part where the fibers constituting the yarn are accumulated more than other parts and a thin part. ) and multifilament yarns, but ordinary fancy yarns such as slub yarns and net yarns are used as the yarns having knots. These fancy yarns may be any of fancy yarns such as slub yarns obtained by twisting or air-treating multifilament yarns, slub yarns obtained by spinning, and net yarns, or fancy yarns other than those mentioned above. Multifilament yarns are ordinary yarns that do not have knots such as slabs or nets, and examples of multifilament yarns include synthetic fibers such as polyester and polyamide, semi-synthetic fibers such as acetate and triacetate, and rayon yarns. Filament yarns such as recycled fibers such as , Kyupura, and natural fibers are used. Next, the yarn having knots and the multifilament yarn are intertwined. In other words, short fibers or filaments constituting the yarn having knots and filaments constituting the multifilament yarn are partially intertwined with each other. Furthermore, loops are formed on the surface of the yarn. This loop must be formed on the yarn surface of at least the thin part of the yarn,
It is preferable that it is formed throughout the longitudinal direction of the yarn. Further, the loop may be formed in either short fibers or filaments constituting a yarn having knots, or filaments constituting a multifilament yarn. Of course, it may be formed on both the yarn having knots and the multifilament yarn. Next, the spun-like fancy yarn of the present invention will be explained using illustrated examples. Figure 1 shows an example of the spunlike fancy yarn of the present invention, which is composed of a slub yarn and a multifilament yarn obtained by twisting multifilament yarns in a designed manner. Thick part 1 that reflects
and a thin portion 2 reflecting the yarn portion other than the slab portion. The slub yarn and multifilament yarn are strongly entangled in the thin portion 2. On the other hand, in the thick portion 1, the slub yarn and multifilament yarn are hardly intertwined, or even if they are intertwined, the degree of intertwining is low, and the filaments of the multifilament yarn are entangled with each other to cover the slab portion. It's getting old. Furthermore, there are fine loops 3 throughout the length of the yarn, which cover the surface of the yarn in a fluffy manner, and the difference in thickness at the boundary 4 between the thick and thin portions is alleviated and becomes smooth. The difference in thickness of the thread as a whole is smaller than that of the original slub yarn. On the other hand, the conventional slub yarn obtained by the designed twisted yarn shown in Fig. 3 has a thick part 1.
At the boundary portion 4 between the thin portion 2 and the thin portion 2, the difference between the thick and thin portions changes rapidly. The above-mentioned spun-like fancy yarn of the present invention can be manufactured using, for example, a fluid treatment that gives entanglement or loops to the yarn, so-called taslan processing. FIG. 2 is a process schematic diagram showing an example of the manufacturing process of the spun-like fancy yarn of the present invention, in which yarn 5 having knots such as slub yarn or net yarn is fed from the first feed roller 7 to multifilament yarn from the second feed roller 8. The threads 6 are each fed to a jet nozzle 9. The yarns 5 and 6 become intertwined with each other due to the disturbance effect of the compressed air supplied to the jet nozzle 9, and a loop is formed on the surface of the yarn, which is then passed through the delivery roller 10 and wound into the package 11 as a spun-like fancy yarn. It will be done. At this time, the yarn 5 having knots and the multifilament yarn 6 are fed from the respective feed rollers 7 and 8 to the jet nozzle 9 in an overfeed manner. The degree of entanglement of the two yarns and the amount of loop formation are determined by adjusting the overfeed rate, the compressed air, etc. In particular, when the overfeed rate is increased, entanglements and loops are effectively formed. The overfeed ratios of the above two yarns may be the same or different, but in order to form many loops on the surface of the yarn, it is necessary to overfeed a multifilament yarn, which has better opening properties than a yarn with knots. It is preferable to make the yarn ratio higher than that of a yarn having knots. In order to form fine loops, it is preferable to use a multifilament yarn with a fine single filament fineness, and the overfeed rate of the multifilament yarn is preferably about 8 to 30%.
In the above-mentioned fluid treatment, loops are likely to be formed in the thin portions of the yarn, and loops are less likely to be formed in the knots, but loops may not be formed in the knots. (Function) Since the spun-like fancy yarn of the present invention has a yarn having knots and a multifilament yarn intertwined, the difference in thickness of the yarn having knots is alleviated by the interlacing. Moreover, the above-mentioned difference in thickness is also alleviated by the loops formed on the surface of the yarn. Furthermore, the loops have a cushioning effect to relieve the tension applied to the yarn, and also give the yarn a spun-like feel and appearance with high bulkiness. (Example) Hereinafter, the present invention will be specifically explained with reference to Examples. Example 1 Polyethylene terephthalate multifilament yarn 150d/24f as core yarn, polyethylene terephthalate multifilament yarn as effect yarn
Slab yarns were produced with a twist count of 550T/M using a design twisting machine using 150d/72f and polyethylene terephthalate multifilament yarns 50d/24f as presser yarns, respectively. At that time, the overfeed rate was set to 2% for the core yarn and 3% for the presser yarn, and the overfeed rate for the effect yarn was varied in the range of 5% to 70%. Obtained slub yarn 350d/120f (yarn A)
A fancy yarn was manufactured using polyethylene terephthalate multifilament yarn 150d/72f (yarn B) according to the manufacturing process shown in FIG. 2 and under the conditions shown in Table 1. As a jet nozzle, it was developed in 1974.
The nozzle shown in Figure 7 of Publication No. 1673 was used.

[Table] The yarn obtained in this way has a bulky property with a relaxed difference in thickness at the boundary between the thick and thin portions, and a large number of fine loops in a fluff-like manner over the entire surface of the yarn. It was a spun-like fancy yarn, and the yarn layer of the yarn package cage did not easily collapse. When this yarn was knitted using a 14-gauge jersey knitting machine, it had good unwinding properties from the yarn package and could be knitted without any trouble. When this knitted fabric was dyed and finished using a conventional method, a product with a slub-like appearance with natural thick and thin spots and a gentle texture with fine fluff-like loops on the surface of the knitted fabric was obtained. . Example 2 A cotton slub yarn was produced by intermittently changing the draft rate in the spinning process of 100% cotton. Using the obtained cotton slub yarn 16/- ^, S (yarn C) and nylon multifilament yarn 140d/48f (yarn D), fancy yarn was produced according to the same manufacturing process as in Example 1 and the conditions shown in Table 2. Manufactured.

[Table] In the yarn obtained in this way, the cotton slub yarn is covered with the nylon multifilament yarn, and both yarns are intertwined, and the thickness difference in the slab part of the cotton slub yarn is gentle, and The loop was made of nylon multifilament yarn and was formed into a fluffy shape. When this yarn was knitted into a knitted fabric with a rubber knitting structure using a 12 gauge flat knitting machine,
The yarn package had good unwinding properties and could be knitted without any trouble. When this knitted fabric was dyed and finished using a conventional method, a product with a supple bulky touch and an innovative appearance that harmonized the heathered and slab textures was obtained. Example 3 Polyethylene terephthalate multifilament yarn 150d/96f, polyethylene terephthalate multifilament yarn 100d/48f, nylon multifilament yarn 140d/48f, and polyethylene terephthalate multifilament yarn 175d/72f were each supplied to a Taslan nozzle, and the Taslan nozzle caused intermittent air disturbance. Four types of slub yarns were produced in which interlaced portions (slab portions) and non-entangled portions were alternately formed in the longitudinal direction of the yarn. The resulting slub yarns were combined with multifilament yarns as shown below to produce spunlike fancy yarns of the present invention according to the steps shown in FIG. 2 and under the conditions shown in Table 3. In the following sample No. 1, two multifilament yarns were drawn together and fed from the feed roller 8. Sample No. 1 Slab yarn 150d/96f and polyethylene terephthalate multifilament yarn (hereinafter referred to as PET yarn) 50d/48f and PET yarn
A matching thread with 50d/12f. No.2 Slab yarn 100f/48f and cationic dyeable polyester multifilament yarn
100f/36f. No.3 Slab yarn 140d/48f and PET yarn
150d/48f. No. 4 Slab yarn 175d/72f and rayon yarn 75d/30f.

[Table] In each of the yarns obtained as described above, the boundary between the thick part due to the slab part and the thin part other than the slab part has a gentle shape, and there are also countless fine loop-shaped fluffs on the yarn surface. It was formed in a very bulky manner. In yarn No. 1, the slub yarn formed the core, the multifilament yarn formed the sheath, and the filaments of the multifilament yarn mainly formed the loop. Furthermore, the slab portion was covered with multifilament yarns and was partially entangled. In yarn No. 2, the unentangled portion of the slub yarn and the multifilament yarn were intertwined together, a large number of loops were formed by the filaments of both yarns, and the slub portion was slightly entangled with the multifilament yarn. In yarn No. 3, the slub yarn formed a sheath portion, the multifilament yarn formed a core portion, and the filaments of the slub yarn mainly formed a loop. Although the slab part was hardly intertwined, both yarns were strongly intertwined at the boundary between the thick part and the thin part. The thread of No. 4 had a thread form almost similar to that of the thread of No. 1. Furthermore, all of these threads have good weaving and weaving properties, and the resulting products have excellent bulkiness.
It had a desirable sense of warmth. (Effects of the invention) Since the yarn of the invention has the above-mentioned structure, it has a spun-like texture and appearance with excellent bulkiness, and the yarn layer of the yarn package does not collapse easily, making it easy to transport. It is difficult for cargo to collapse inside the container. Furthermore, it exhibits superior weaving and weaving properties compared to conventional fancy yarns.
