Abstract

PURPOSE:To prevent the separation of chemical fiber and raw silk in the degumming process, by carrying out the boiling water-shrinkage of a combined raw silk raw silk in the absence of tension just before combining the chemical fiber with the raw silk. CONSTITUTION:The hot water tank 11 containing boiling or nearly boiling water is placed under the reeling tank 2. The chemical fiber yarn (b) unwound from the bobbin 12 is transferred through the hot water tank 11 in the absence of tension to effect the shrinkage of the yarn, and is introduced into the threading pipe 10. In the case of twisting a combined yarn of chemical fiber yarn (b) and raw silk yarn (a) and treating the combined yarn with hot water to effect the degumming of the silk, the shrinkages of the raw silk and the chemical fiber yarn are balanced by this procedure, and the separation of the yarns (a) and (b) can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing composite raw silk in a warp process VC.

By combining conventional raw silk and chemical fibers, is it possible to create a composite yarn that overcomes the disadvantages of raw silk? What you get is, for example, JP-A [f', 45
It has been proposed in Japanese Patent No. 7-185409.

However, if you only make synthetic fibers and raw silk T-composite,
Due to the difference in the degree of shrinkage of both yarns, the chemical fibers shrink during the scouring process, and as shown in Figure 6, the chemical fibers and raw silk are separated by 1if.
It causes inconvenience.

The purpose of the present invention is to provide a complete method for producing composite raw silk in the warp process that eliminates all the disadvantages of the present invention. The chemical fiber is then combined with raw silk by immersing it in a hot water tank at or near the boiling point in a tension-free state, shrinking it, and then combining it with raw silk.

An example of implementing the present invention will be explained with reference to the accompanying drawings.

Is (1) in the drawing the reeling device? The reeling device (1) is
The reeling tank (2), the welding device (3) and the weaving device (4) above it
Raw silk crimped with 1 clasp holder (3)
), and then the threaded part (7) formed between the drum wheel f5+ +61, and after the full thickness of the temporary stitching is completed, the fineness sensor (
8)? Then, it is wound up onto a small frame (9).

The structure is not particularly different from the conventionally known yarn reeling device (1), and there is also a yarn threading pipe (1 One of the features is that the chemical fiber' is exposed to the system during reeling through the yarn threading pipe (1 (ll'), and the raw silk a is doubled and wound around the small frame +911/C. There is no particular difference from that disclosed in JP-A-57-183409.

In the present invention, a hot water tank ←υ with a temperature near the boiling point or the reel is provided at the lower part of the reeling tank (1), and the bobbin 02)v? - Derived from the wrapped skin thread and said boiling water tank αυ
After the inner part is moved without tension and contracted, 1 fl.
'(r) The curved thread was guided into the pipe (10).

To explain this in full detail, the hot water tank αυ is relatively long, steam pipes 10 are arranged modestly along the 8 directions of the length, and a large number of spout ports (13 spouts) are provided on the upper surface of the steam vibrator Q31. The chemical starvation was made to meander by the movement of the hot water generated by the steam ejected from the outlet (13aJ), and the nuclear chemical fibers were heat-shrinked without being stretched.

In the drawing, 0 is a guide roll that completely prevents the chemical fiber from lifting up.

In the case shown in No. 1N, the yarn threading via (IO + fully hot water tank σ1) is extended and protruded, and the entire passage awning inside the threading pipe 0()) is heated even within the threading vibrator (10).
I tried my best to give.

However, as shown in FIG. 4, if necessary, a slight tension, for example, a few grams, may be applied between the hot water tank aυ and the reeling tank tel.
Attached tension device (applied if installed).

In the illustrated example, an arc-shaped water flow guiding plate (16) is provided inside the sheet reeling t21, and a shogata pipe (one duct) is installed. After raising the cocoon, the cocoon C was placed in a concentrator (4) and the silk was slowly reeled in a rotary manner at the center of the cocoon.

Next, we will explain the case where a large number of polyester fibers are drawn together and combined into raw silk using this device.
When the wound chemical W4 fibers are transferred into the hot water tank in a tension-free state, the chemical fibers shrink, and when they pass through the cord collector (4) in this state, raw silk a is formed around the outer periphery of the chemical fibers. is wrapped in a shape (; is compounded with the mantissa in the kennel part (7)? After the n is given, the small #f91 is taken, and these steps are similar to the previous reeling process. Nothing is completely different.

Chemical fibers and raw silk &? When combining,
Next, when the composite yarn is twisted and then subjected to hot water fIMr for scouring, the two yarns aSb separate as soon as the raw silk a and the chemical fibers shrink. The situation shown in Figure 5 can be maintained.

(Appropriate hot water tank temperature and processing time are shown in Table V below.
After carrying out the test shown in C, it was found that it was necessary to treat the product with hot water at 96°C or higher for 1 second or more.

An example of all such treatments is the one disclosed in Japanese Unexamined Patent Publication No. 57-183409, which shows that the awns wound around a bobbin and immersed in a hot water bath do not survive even after being immersed in hot water at 50°C for 1 hour. 5 m/
The degeneracy was only about 2Qwa/m, and even when immersed in hot water at 96°C for 1R, the degeneracy was only 2Qwa/m, and sufficient shrinkage could not be obtained.

As described above, in accordance with the present invention, immediately before compounding with the chemical fiber yarn, it is immersed in a hot water bath at or near the rising point in a tension-free state. After shrinking it, it is combined with raw silk to create a chemical fiber. Is it possible to sufficiently reduce the VC?
The effect of VC is that it is possible to prevent separation of chemical fibers and raw silk during the scouring process and to obtain an extremely good composite yarn.
