Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the production of a cilia-recognized composite yarn, more specifically, a composite yarn in which a large number of fluffs of short fibers protrude from the surface of the composite yarn, which is a composite yarn of a spun yarn and a continuous yarn. It is about the method.

Conventionally, there has been a method of manufacturing covered yarn by supplying staple fibers and continuous yarn to an air and centrifugal spinning yarn device using a rotary spinning chamber, as disclosed in Japanese Patent Publication No. 47-1026 and Japanese Patent Publication No. 49-238. It has been proposed in Publication No. However, the methods described in these publications use a continuous yarn as a core yarn, and the purpose is to obtain a covered yarn in which a spun yarn consisting of staples is wound around the core yarn. Therefore, there are restrictions on the continuous yarn supply method and spinning mode, and the resulting covered yarn is also limited.

The present invention is different from the above-mentioned known examples and aims to achieve the following matters. [11] In terms of yarn structure, the continuous yarn is wrapped tightly around the spun yarn that is being formed in the yarn room from the staple east, resulting in a covering shape, or the continuous yarn and the spun yarn are twisted together. get something.

{21 By covering or twisting the continuous yarn material, a yarn structure is created in which the staple east is carefully integrated into the spun yarn body. [31] To explain item (③) in detail, staples are supplied from multiple locations to form spun yarns,
The staples for forming the spun yarn main body are supplied from one point, and the staples for forming the fluff are supplied from the remaining points near the joining point of the continuous yarn and the spun yarn, so that the connection between the spun yarn and the continuous yarn is supplied. A large number of staples are projected as fuzz on the surface of the composite yarn, and the single fibers forming the fluff are tightly held on the composite yarn main body by winding the continuous yarn.

■ Enables the composite yarn described in the glue section to be stably fed into paper without yarn breakage.

The purpose of the above is to supply the staple east from the sekiori supply pipe to the inner wall of the rotating spinning chamber, to re-concentrate the staples that constituted the east, and to spin this into a spun yarn, as well as to spin it into the spinning chamber. When producing a composite yarn by supplying a continuous yarn material to the lily yarn chamber and combining it with the spun yarn, short fibers are supplied at or near the point where the spun yarn and the continuous yarn material are combined in the liquid yarn chamber. This is achieved by making the short fibers protrude as a large number of fuzz on the surface of the composite yarn.

In particular, in the above method, the continuous yarn material is fed with yarn feeding tension (T,)
The objects of the present invention are advantageously achieved by supplying the yarn to the rotary yarn chamber at 25 or less, more preferably in the range of 2 to 25 tons.

In addition, the central axis of the yarn discharge pipe and the continuous yarn supply pipe are 5
It is preferable to configure it so that it extends beyond the skin. Then, a plurality of open twill supply pipes used for supplying staple fibers are constructed, and one
One is directed to the wall surface above the largest folding part of the paper yarn chamber, which plays the role of fiber transfer and accumulation, and the other is directed to the yarn discharge pipe below the largest folding part from the opening supply pipe, which is installed separately. The yarn is fed toward the yarn guide surface formed by the section up to, preferably near the point where the continuous yarn and the spun yarn join together. Specifically, the embodiment of the present invention will be explained with reference to the drawings in comparison with a comparative example. FIG. 1 shows a comparative example in which the staple east and the continuous yarn material are supplied to the wall surface above the maximum folding part of the twill yarn chamber. First, the staple east 1 is supplied from the supply pipe 3 to the grade yarn chamber 5 as separate spread fibers 12.

On the other hand, the continuous yarn material 2 is introduced from the supply pipe 4, and is combined with the spun yarn 9 formed from the staple east at the union point 7.
The continuous filament 2 is twisted on the surface of the spun yarn 9 in a covering or interlocking manner. This covering-like or interlocking-like yarn form is determined by the yarn feeding tension T, of the continuous yarn material 2, and T, S25 (y) preferably 2 (y) ≦
A good composite yarn can be obtained when T is ≦25 (even). Next, the composite yarn is pulled out from the lower delivery rollers 7 and 8 through the yarn discharge pipe 6. On the other hand, in the method of the present invention, in addition to the above-mentioned embodiment, as shown in FIG. 2, opening supply pipes for the staple east are provided at multiple locations, and in the case of FIG. supply.

In this case, the tip of the supply pipe 11 is placed on the yarn guide surface of the spun yarn 9 formed by the staple fibers supplied from the supply pipe 3, preferably near the point 7 where the spun yarn 9 and the continuous yarn 2 join. It is preferable to put it inside your finger. Here, the supply staples 1 and 1' may be made of the same material or may be made of different materials. In particular, when different materials are used, it can be uniformly applied as a third component to the surface of the composite yarn. In the case of the opening shown in FIG. 2, the second opening supply pipe 14 is provided above the supply pipe 4 for the continuous thread material, and the staple east 1' is introduced from the supply pipe 4 at the same time as the continuous thread material 2. be.

In this case, the staple east 1? is very well formed at the joining point 7 of the spun yarn 9 and the continuous yarn material 2? In the composite yarn 16 which is twisted and pulled out downward through the yarn discharge pipe 6, the staple east 1' is uniformly attached and is tightly joined to the surface of the spun yarn by the continuous yarn material 2. I can do it. If the morphology of the composite yarn obtained by the conventional method and the method of the present invention is explained as a model using FIG. 3, first, the composite yarn obtained by the conventional method shown in FIG. 1 is as shown in FIG. As shown, the continuous yarn material 18 is twisted on the spun yarn main body 17, and the fluff ends constituting the spun yarn 17 are only slightly protruding from the twisted yarn surface. On the other hand, in the composite yarn obtained by the method of the present invention, the staples 20, 21, etc. of the third component are attached to the surface of the spun yarn main body 17 by twisting by the continuous yarn material 18, as shown in the opening of FIG. The yarn structure consists of a spun yarn main body 17, a continuous yarn material 18, and a surface layer forming stable (for example, 20).
It will be composed of three parties. For reference, Figure 3C shows the appearance of a yarn twisted using a conventional covering twisting machine (ring-spun yarn covered with a continuous yarn); Due to this relationship, the bulkiness is low and the fluff length distribution is unstable, there are many overlong fluffs, and the composite yarn is likely to slip and move between the spun yarn main body 22 and the continuous yarn material 18. According to the present invention, a composite yarn having the following features can be obtained: 01 The staples of the third component are uniformly attached to the outer periphery of the yarn, and in particular take the form of a fluffy bridge that protrudes from the yarn surface, resulting in an extremely cilia-like appearance. It can be applied to the field of ciliated yarn, which has not conventionally been possible with open-end spun yarn of short staple fibers.

'2) The material of the fiber to be attached as the third component, the fiber length,
By variously changing the denier, etc., it is possible to obtain a wide range of novel yarns.

[3' Since the continuous yarn structure twists the third component tightly, there are no problems such as shedding of fuzz. Furthermore, since the stable is attached to the surface separately from the spun yarn main body, the fluff ends protrude straight to the surface and are not restrained by the ends inserted into the spun yarn of the main body. Therefore, when it is made into a knitted fabric, the fluff ends protrude from the surface, making it possible to create a fancy-looking, high-quality product made of straight fluff like a conventional raised yarn. ■ The above composite yarn can be obtained in one step using the open-end spinning method, resulting in extremely high productivity.Furthermore, by adopting the aspect of the present invention, the yarn can be spun stably without problems such as yarn breakage. I can do it.

Example In the weaving yarn mode shown in FIG. 2A, polyamide multifilament 7 and -34fil were used as the continuous yarn component 2, and acrylic fiber 1. Short-cut wool (average fiber length 50 ribs) was supplied to the staple component 1' as the third component on the mother, 44 side.

The spinning conditions are as follows. Rotation speed of rotary spinning chamber 5
3000 pm Supply of staple components 1, 1': Spreading air by ejector Air pressure of ejector: 0.5 kg'c Spinning count of fin spun yarn 9: 1/32 (metric type) staple East 1'
Supply ratio: 30% with stable ratio Coefficient of spun yarn 9: K = 3.5 Yarn feeding tension T,: T, = 12 filaments are twisted on the surface of spun yarn 9 Covering twist count: Approximately 60 twists/spinning speed
The composite yarn obtained at 50 m/min has wool fibers attached to the surface of the spun yarn main body made of acrylic fibers in a coated manner, and the wool fibers are tightly covered by filament tubes, resulting in a yarn form in which the wool fibers have their fluff. The ends protruded into the outer yarn layer in a slate shape, giving the yarn an appearance extremely similar to that of woolen wool, and the uniformity of yarn unevenness was good.

As for final product applications, it can be suitably applied mainly as cilia-like knits and ciliary-like fabrics.
