Abstract

Spun yarn and multifilament yarn are doubled, interlaced and cohered, while the above two yarns are fed in a way that the spun yarn is fed less than the multifilament yarn by 0.5-2.0%. The interlaced yarns go through fluid nozzle to give interlaced composite yarn which has appearance of spun yarn as well as luster, feel of filament yarn.

In the present invention, by entangled the yarn yarn and multifilament yarns to form the fuzz and multifilament yarn on the outside of the yarn yarns to entangle each monofilament, the entanglement having both the shape of the yarn and the gloss and feel of the filament yarn at the same time An improved manufacturing method of a composite yarn.

In the past, attempts have been made to obtain a composite yarn having both characteristics by combining a yarn composed of staple fibers and a continuous filament yarn. In general, a filament yarn is used as a screening method in a spinning process, particularly a spinning process. It can be classified into two types of core yarn (Coreyarn) method that is arranged around the yarn, and yarn spinning yarn and filament yarn by hollow spindle.

However, the former is mainly intended to supplement the physical properties such as the quality improvement of the yarn, so it is difficult to express the gloss and the touch of the filament yarn to a sufficient degree, and the latter is relatively twisted to give the unique luster and feel of the filament yarn. There was a problem that was difficult to make.

In addition, as in the case of Korean Patent Publication No. 89-2036, there is also shown a method of spraying synthetic fiber multifilament yarns having different feed rates from an air spray nozzle to mutually entangle the yarns to produce the effect of spun yarn. There was a shortcoming in lack of sufficiently expressing the characteristics of the appearance, and in addition, when this method is applied to the interlacing treatment between the yarn and the multi-filament yarn, when the yarn is fed to the overfeed, the yarn is overextended, resulting in cutting and splitting yarn. This caused unsuitable problems such as single yarns or clogged fluid nozzles. The present invention solves the above problems, it is possible to make full use of the yarn-specific shape, and at the same time provide an improved manufacturing method that can produce an improved composite yarn that can satisfactorily exhibit the rich appearance and flexible touch of filament yarn According to the accompanying drawings, the following will be described.

1 is a schematic diagram illustrating the entire manufacturing process of the present invention, in which the multifilament yarn 1 is supplied from a creel to the fluid treatment nozzle 4 and the yarn 2 is fed to a feed roller 3, 3 '. By the multi-filament yarn 1 is supplied at a slower rate. Both yarns are spun together in the fluid treatment nozzle 4 to entangle and focus individual monofilaments of the multifilament yarn 1 and the outer hairs of the spun yarn 2 by the action of a fluid to form an entangled composite yarn 6. It is heat set in the heater 7 via delivery rollers 6 and 6 'and then wound by a winding roller 8.

2 is an exemplary view of a schematic structure of a fluid nozzle, the present invention will be described in more detail with reference to FIG.

Since it is extremely difficult to entangle the spun yarn and the multifilament yarn with a given twist, in the present invention, the yarn is subjected to examination by supplying the yarn under under feed, and the outer side of the multifilament yarn and the yarn that is relatively over fed By bridging and connecting fine hair, it becomes an effect company.

In FIG. 2, the yarn 2 is given an under feed by the feed rollers 3, 3 ′ in passing through the guide 10 and the fluid treatment nozzle 4. Pass through the central axis of the eye guide (11). Since the multifilament yarn 1 is spun by the spun yarn in the guide 10 and is relatively over-feeded by the under feed of the spun yarn when passing through the fluid treatment nozzle 4, the yarn guide 11 It is arranged in the periphery.

On the other hand, if the yarns and multifilament yarns are supplied side by side at the same rate, the yarn and multifilament yarns are combined before the yarns and multifilament yarns are inserted into the nozzles due to the twisting of the seam from the package, the torque of the yarn itself, or the spraying from the nozzles. The integrated effect of the opening of the multifilament yarns in the nozzle is insufficient, thereby interfering the entanglement and the converging action between the spun yarn and the multifilament yarns. 0.5-2% of feed rate difference between spinning yarn and multifilament yarn to facilitate entanglement and concentrating is preferable. If the feed rate difference is less than 0.5%, the convergence is poor and if it exceeds 2%, multifilament yarn As a result of looping, the post-processability becomes poor and at the same time excessive tension is applied to the spun yarn, resulting in a defect in poor focusing. In addition, increasing the pressure of the compressed air jet hole within the range allowed by the tension of the multifilament yarns helps to increase the focusing and improves the convergence even if the fineness of the monofilament yarns constituting the multifilament yarns is thin and large. There are no particular restrictions on the spinning yarns and multifilament yarns used, and an appropriate selection can be made according to the target product.

Referring to the manufacturing method of the present invention according to the embodiment as follows.

EXAMPLE

Use 50 'S polyester spinning yarn and 70d / 24f nylon multifilament yarn, but the processing speed of 400m / min, 1.7% of yarn's under feed and 3.5kg of compressed air blower As a result of interlacing under the condition of cm², the workability and the binding and weaving property of the yarn were good. When weaving the fabric using the yarn, it showed the natural shape of the yarn and smooth touch and abundant draft property of the nylon multifilament yarn. In addition, a natural two-tone effect can be obtained according to the selection of the dye.

Claims (1)

Since yarns and synthetic fiber multifilament yarns are spliced together before being fed to the fluid treatment nozzle, the entanglement is focused so that yarns are supplied under 0.5-2.0% under feed than synthetic fiber multifilament yarns. Method of manufacturing a kinak composite yarn characterized in that.
