Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for producing a special slub yarn having a silky 7:c texture and excellent cohesiveness.

[Prior art]

Is there a conventionally known method of forming slub yarn by overfeeding yarn into the heating area of the core yarn that is being false twisted and winding it around the core yarn? The resulting slub yarn had poor cohesiveness and had frog spots in the subsequent process, and since it was a crimped yarn, it lacked a soft and silky texture.

[Purpose of the invention]

The object of the present invention is to solve the problems of the conventional method and to provide a simple method for drawing a special slub yarn that has 1-2 slub-gathering properties and a silky texture.

[Fu Cheng of invention]

The present invention forms a slub yarn by overfeeding the heated region VC-wound yarn of the core yarn, which is being falsely twisted by the swirling fluid, and winding it around the core yarn, and then by using the stirring fluid to wind the VC-wound yarn around the core yarn. , is a method for producing a special slub yarn characterized by intertwining the slub yarn.

The present invention will be described in detail below with reference to the drawings. Fig. 1 is a side view showing an example of an apparatus used for carrying out the present invention, in which the core thread (1) is connected to the guide (3), the spring tensioner (4' ) to the second feed roller (A)
(A') is gripped by the delivery roller (/) and travels while being falsely twisted by the swirling air flow 5 in the fluid processing device ffi (g).

On the other hand, the thread (2) forming one slab is guided by the guide (3'
) via the spring tensor (ri') to the first feed roller (,lt) C! ;') i/Ko-twirled core thread (1)
The core yarn (1) is fed from a guide (7) provided in the heating area at a speed higher than the running speed of The fibers are strongly mixed and intertwined by the disturbed air in the fluid yarn processing device (&), and then delivered to the delivery roller (IO).
n1 gate tensor C/l)”i:14
Stack it up and package it with a wind roller (12) (/
◇ At this time, the length of the slab is determined by the overfeed rate of the winding yarn (K) with respect to the running speed of the core yarn (1), and the relationship between the core yarn (1) and the winding yarn supply guide (7). It is possible to change the distance as appropriate.

Next, a preferred embodiment of the fluid treatment device (Ii) will be explained in detail. , l is a vertical side view of the fluid treatment device, FIG. 3 is a cross-sectional view taken along the line x-x' in FIG. 2, and FIG. q is a sectional view taken along the line Y-Y'. The air flow injected from one injection hole (2f/) into the downstream part (ko/) of the thread guide hole first becomes a turbulent flow in the upstream part (kol) of the thread guide hole, and then passes through there. The slub yarn is entangled to improve convergence, and then the entire air flow hole (15)
CB') flows into the downstream part (27 holes) of the yarn guide hole to form a swirling flow and give a false twist to the core yarn (1).

The present invention will be explained in more detail below using practical examples.

[Example 1] Fluid processing equipment @'fi shown in Fig. 1: Using the equipment shown in Fig. 7, polyester filament yarn jtOa7.3Af was used as the core yarn and winding yarn, processing speed was 750 m7 minutes,
When processed under the following processing conditions: overfeed rate of the wound yarn 30%, distance from the winding yarn supply kite to the core yarn 20 mm, 1st air pressure Jkg/Cr1I, Silky 11 m, and A sturdy holding slab yarn was obtained in which the slab part was made of Uosanmei.

[Example]

Using the same device as in Example 1, 60 strands of cotton yarn was used as the core yarn, and 100 d/A of acetate filament yarn was used as the hoe yarn.
Hirof is used and the processing speed is io.

When treated under processing conditions of m7 minutes, overfeed rate of the wound yarn 20%, distance from the wound yarn supply guide ( ) to the core yarn, 20 degrees, and a sudden injection pressure of -1 to 91 crl, silky A special slub yarn with a design effect dotted with glossy slubs and a special slub yarn with a fan of the prefecture's notes was obtained.

〔Effect of the invention〕

According to the present invention, which is grooved as described above, a special slub yarn having excellent cohesiveness and silky texture can be easily obtained, and its industrial value is extremely large. .
