The present invention treats the supplied core yarn and the effect yarn by injection air first and then false twists it, followed by injection air treatment in the second step to produce a woolly like dyeing yarn having excellent touch and focusing properties. It is about how to.

The conventional TasIa n yarn manufacturing method for preparing oligozo dye using synthetic filament multifilament yarn uses multifilament yarn as a yarn, so the processed yarn shows a spun yarn appearance in appearance but is rough for the touch. It was inconvenient to wear when used and had to increase the air pressure in order to increase the focusing was not economical.

In view of this problem, there is a known method of connecting two kinds of doctors with different orientations at the same time by applying them to the gas treatment apparatus and then connecting them by a fluid treatment device. It was uneconomical because the fluid pressure had to be increased in order to lower the job performance rate and to compensate for such problems.

In order to solve the problems of the prior art as described above, by treating the core yarn and the effect yarn with the injection air before the combustible processing, it is characterized in that the maximization of the concentration of both is as follows.

The present invention relates to the core yarn (1) and the first injection air treatment device (3) of low pressure under low tension before the core yarn (1) and the effect yarn (2) made of thermoplastic synthetic fiber multifilament yarn Increase the focusing of the effect yarn (2). In the present invention, the core yarn 1 uses a birefringence of 20 × 10 ^{−3 to} 50 × 10 ⁻³ , and the effect yarn 2 uses a birefringence of 70 × 10 ⁻³ or more.

When the birefringence of the core yarn 1 is less than 20 × 10 ⁻³ , the safety of the processed yarn decreases, and the strength decreases and the peeling phenomenon occurs severely when it is straight or comfortable.

In addition, when the birefringence of the core yarn 1 exceeds 50 × 10 ⁻³ , the ringing effect is lowered and the dye transfer effect cannot be expected. The characteristics of the uljo dyeing yarn manufactured by the present invention is that the core yarn (1) having a large bulkiness and the effect yarn (2) having a small bulkiness are strongly concentrated, thus exhibiting the feel of Ulrizo while having the same appearance as a spun yarn.

1 is a schematic diagram of a manufacturing apparatus for carrying out the present invention, in which the core yarn 1 and the effect yarn 2 are primarily mixed in a jet air treatment apparatus 3 and combusted in a combustible spindle 7. . Here, the heat is fixed to the first heater 5 between the first supply roller 4 and the second supply roller 8.

The combustible work passing through the second feed roller 8 is strongly concentrated in the second spraying air treatment device 9 and then passes through the third feed roller 11 and the oil ring device 12 to complete the product package ( 13) is mentioned.

EXAMPLE

By means of the apparatus of FIG. 1, a polyester synthetic fiber multifilament yarn 120 ^D / 36 ^F having a birefringence of 28 x 10 ^-3 of the core yarn 1 and a poly birefringence of an effect yarn 2 of 80 x 10 ^-3 Ester-based synthetic filament 150 ^D / 48 ^F was prepared under the following conditions.

(1) 1st heater temperature: 210 degreeC

(2) Number of combustible stations: 1750TPM (Z stations)

(3) Extension ratio: 1.025

(4) Fluid handling pressure (primary): 0.5kg / cm ²

(5) Fluid treatment pressure (secondary): 2.5kg / cm ²

(6) Supply ratio of 2nd supply roller and 3rd supply roller: + 4.0%

The result of processing after weaving by using 450rpm Wat er jet loom without using the weaving process for light and weft yarns is as follows.

Talent rate:

Peeling property: KSK 0501 (BRUSH & SPONGE method)

Wear resistance: KSK 0604

Claims (2)

In the manufacture of ulijo dyeing yarn by twisting the core yarn and effect yarn made of thermoplastic synthetic fiber multifilament yarn with different orientation and then spraying air treatment, the core yarn and effect yarn are first sprayed air treatment before combusting. Woolly like dyeing yarn with excellent touch

Method of manufacture). The method of producing a woolly dibasic yarn according to claim 1, wherein the core yarn having a birefringence of 20 × 10 ^{−3 to} 50 × 10 ⁻³ and an effect yarn having a birefringence of 70 × 10 ⁻³ or more are used.
