The present invention relates to a composite processing yarn (hereinafter referred to as "composite processing yarn") mixed with one or two or more synthetic filament yarns and one or two or more predominantly natural fibers, short fiber yarns, and a method of manufacturing the same. More specifically, the present invention relates to a composite processing yarn and a method of manufacturing the same, which are soft to the touch and can impart various functionalities, which can make the appearance regular or irregular in various forms, and are suitable as material yarns for clothing or interior fabric.

As a conventional technique of combining a synthetic fiber long fiber material yarn and a natural short fiber material yarn, there is simply a method of simply combining these two types of yarns in a general general twisting process by a combination method, but in this case, Since the quality of the composite yarn is completely dependent on the yarn used, it cannot give any change in appearance or physical properties and has a hard touch.

Another conventional technique is a method of arranging yarns in weaving, which is a method of manufacturing a fabric by simply arranging a filament filament yarn and a natural short fiber yarn in a weaving preparation process. There was a problem that can not deform or change the quality.

Another conventional technique is a method of incorporating the filament filament material yarn during the spinning process, but the filament filament material yarn is arranged only in the inner layer, and the short fiber forms the outer layer, thus only changing the appearance of the filament. Not only can not be given a variety, but also can not express a variety of functional and there was a problem of low production efficiency.

Therefore, an object of the present invention is a composite processing yarn and a composite fiber that can be combined with a long fiber material yarn and short fiber material yarn so as to solve the problems of the prior art, the surface feel can be smooth and various appearance and impart various functionality It is to provide a manufacturing method.

The present invention is arranged in the direction of the yarn axial yarn fibers and short fiber material yarn mainly made of natural fibers are soft to the touch, and various functions such as sweat-absorbing quick drying according to the material selection, streaky by controlling the thickness and shape Effect can be expressed, and the color can be varied into two or more kinds, and the section having the left margin and the section having the accident are arranged alternately so that the resilience is good and thereby The present invention provides a composite twisted yarn that can omit the twisting process for fabric production and a method of manufacturing the same.

In order to achieve the above problems, the manufacturing method of the composite processing yarn of the present invention includes one or two or more synthetic fiber long yarns (1, 2) and one or two or more short fiber yarns (3), respectively. The feed rollers 4, 5, and 6 are fed into the mixing device 7 to mix them, followed by heating to the first hot plate 8 at a temperature of 15 to 70 ° C. lower than the melting point of the filament filament yarn. It is characterized in that the twisting treatment with the twist spindle (9) while stretching, the stretching roller (10) at a draw ratio of 0.8 to 1.8 times, and then wound up after the final heat treatment to the second hot plate (12).

In addition, the composite processing yarn manufactured by the manufacturing method of the present invention, the section having a left margin and the section having a coincidence are alternately repeated, the section is 0.1 compared to the average fineness of the composite processed yarn ~ 20 times fineness and (ii) 0.1 ~ 30 times the apparent thickness compared to the average thickness of the composite yarn and (i) the number of monofilament strands 0.1 ~ 1.0 times the number of strands of the maximum monofilament of the composite yarn It is done.

Hereinafter, with reference to the accompanying drawings, it will be described in detail.

First, the present invention manufactures a composite processed yarn through the process as shown in FIG.

1 is a process schematic diagram of the present invention.

Specifically, the present invention, first, the first to the third feed roller, each of one or two or more synthetic fiber long fibers 1, 2 and one or more short fibers 3 (3) as shown in FIG. They are fed into the mixing device 7 via (4, 5, 6) to mix them.

As the synthetic fiber long fiber material yarn, polyester undrawn yarn, polyester low melting point yarn or polypropylene filament is used, and the short fiber material yarn is rayon, wool yarn, silk, cotton yarn, soybean fiber, hemp ( Iii) short bamboo fiber or bamboo fiber is used.

Hereinafter, the synthetic fiber long fiber material yarn is abbreviated as long fiber yarn and the short fiber material yarn is abbreviated as short fiber yarn.

At this time, the total types of long-fiber yarn and short-fiber yarn to be used are two or more, more preferably 2 to 6.

In addition, the mixing weight ratio of the long fiber yarns (1, 2) and the short fiber yarns (3) is preferably 98%: 2 to 25%: 75% by weight.

If the blending weight ratio of the yarns is out of the above range, the mixing firmness and durability may be halved and the quality of the final composite yarn may be degraded.

The mixing weight ratio of the yarns can be adjusted by the rotational linear velocity of the first to third feed rollers (4, 5, 6).

As the mixing device, the mixing devices shown in FIGS. 2 to 4 may be used.

Specifically, as illustrated in FIG. 2, a cylindrical mixing device may be used to allow twisting by the combustible spindles 9 to be transmitted to the long fiber yarns which do not flow into the mixing device 7.

At this time, the twist block roller 16 is not provided in the outlet part of the mixing apparatus 7.

Using the mixing device 7 as shown in FIG. 2, the twisting by the combustible spindle 9 as shown in detail in FIG. 2 continues in the same direction continuously to the long fiber yarns 1, 2 before entering the mixing device. The short fiber yarns (3) are located between the long fiber yarns (1,2), and the short fiber yarns are naturally twisted by the twisting imparted to these long fiber yarns (1,2). Mixed with (1,2).

Another mixing device 7 may be a mixing device 7 having a high pressure air nozzle 7a as shown in FIG. 3.

Specifically, the filaments of the long fiber yarns 1 and 2 in the mixing device 7 by spraying the high pressure air into the mixing device 7 continuously or discontinuously through the high pressure air nozzle 7a formed in the mixing device 7. By alternately interlocking with the open island, the short fiber yarn (3) is introduced into the section where the filaments are opened, and the long fiber yarn (1, 2) and the short fiber yarn (3) are mixed.

At this time, a twisting roller 16 is installed between the outlet of the mixing device, that is, between the mixing device 7 and the first hot plate 8 so that the twisting imparted by the combustible spindle 9 is mixed. It blocks me from reaching my yarns.

Another mixing device 7 may be a mixing device provided with an electrode donor 7b as shown in FIG.

Specifically, the filaments of the long fiber yarns in the mixing device 7 are generated by applying a charge of the cathode and the anode to each of the opposite sides of the mixing device 7 with the electrode donor device 7b. The short fiber yarn 3 is introduced into the section where the filaments are opened, and the long fiber yarns 1 and 2 and the short fiber yarn 3 are mixed.

At this time, a twisting roller 16 is installed between the outlet of the mixing device, that is, between the mixing device 7 and the first hot plate 8 so that the twisting imparted by the combustible spindle 9 is mixed. It blocks me from reaching my yarns.

Next, the blended yarns are continuously combusted with the combustible spindle 9 while being heated with the first hot plate 8 at a temperature of 15 to 70 ° C. lower than the melting point of the synthetic fiber long fiber material. The drawing roller 10 is stretched at a draw ratio of 0.8 to 1.8 times, and then heat-treated with the second hot plate 12 to be wound up to produce a composite yarn of the present invention.

At this time, some of the yarn (composite processed yarn) mixed by air cushioning with the dust removal nozzles 11 and 13 before and after the final heat treatment with the second hot plate 2 passes through short fibers or machine sections. It is more desirable to remove stray short fibers.

The draw ratio is a value obtained by dividing the rotation linear speed of the stretching roller by the rotation linear speed of the first to third feed rollers.

If the draw ratio is less than 0.8, the running of the yarn deteriorates, making the production difficult, and when the stretch ratio exceeds 1.8, the tension may increase, and a lot of cutting may occur.

In addition, it is preferable that the rotation speed of the bitumen spindle 9, ie, the twist number imparted to the yarn by the bitumen spindle 9, is 2,500 T / M (Twist / meter) or less.

The yarns blended in the above process are twisted by the combustible spindles 9 after passing through the first hot plate 8, so that opposite twists are formed, theoretically having no twist in the fiber axis direction as a whole. 1 If the hot plate (8) temperature is maintained at an appropriate temperature, the long-fiber yarn is melted in a twisted state in some sections, and the shape is fixed. In this section, the twisted shape is maintained even after passing the combustible spindle (9), In the other section adjacent to this section, the opposite twist is given so that the left and right sections are alternately formed.

According to this phenomenon, the number of strands of the mixed filament and heat treated yarns of the filament filament long fiber yarn monofilament is changed by melting.

The composite processing yarn manufactured by the manufacturing method of the present invention described above is repeated with alternating sections having a left margin and a section with a chance, and the sections are 0.1 compared to the average fineness of the composite processing yarn. It has ~ 20 times fineness and (ii) 0.1-30 times the apparent thickness compared to the average apparent thickness of the composite yarn and (i) the number of monofilament strands 0.1-1.0 times the number of strands of the maximum monofilament of the composite yarn.

When the sections of the composite processing yarn have a fineness less than 0.1 times the average fineness of the composite processing yarn, the appearance is monotonous. When the sections are more than 20 times, the runability of the process is poor and the separation of the short fibers is excessive.

In addition, when the above sections of the composite yarn have a number of monofilament strands less than 0.1 times the number of strands of the maximum monofilament of the composite yarn, the mixing of long fibers and short fibers becomes poor, and more than 1.0 times the number of monofilament strands When it has, the left side and the right side are hard to occur alternately, and the resilience elasticity is too strong to feel.
