Abstract

Woolen yarns were processed. Thus, a hank of woolen yarn or wool mixed yarn is loaded on a pair of rotary roller and elongated at optimal elongation temp. (90-130 ≰C) within a internal pressure tank to the critical elongation point. The elongated yarn is wetrelaxed with steam of 100≰C for 15 min at atm. pressure to give coolen yarns having a bulky feeling and shrink-proof.

The present invention relates to a method of processing a wool yarn for imparting excellent shrinkage and voluminous feel to wool or blended wool.

The fiber of natural wool has a fine scale formed around it as shown in FIG. 2 (a).

When spinning fibers of natural wool, the yarn becomes a yarn. When the yarn is washed or rubbed due to the scale of the interlocking fibers, the yarn is shrunk.

In order to increase the anti-shrinkage from natural wool or mixed yarns, it is the method of the present invention that the scales formed on the surface of the wool fiber are partially destroyed or relaxed so that the scales do not contract with each other.

Detailed description of the method of the present invention for achieving this object,

In the pressure tank, a pair of rotary rollers are stretched 1.5 to 1.7 times with the Hank simulated in the pair of rotating rollers, and the yarns are heated at the optimum stretching temperature.

At this time, the optimum stretching temperature is different depending on the number of wool fibers, but usually reaches a range of 90 ℃ to 130 ℃.

In order to achieve a uniform stretching effect during the stretching process, the rotating roller loaded with a hank simulation is continuously rotated.

The limit of stretching is 1.5 to 1.7 times the length of the wool, so stretching is maximized to the limit of stretching.

The processing method of the present invention is completed by naturally shrinking the stretched yarn to its original length, and then adding an increase again and subjecting it to wetting and relaxing to the original length of about 15 minutes under wet heat of 100 ° C. or less.

When the yarn is stretched, it is extremely attached to the gripping points of the wool fibers, which constitutes the woolen yarn, accompanied by a slight slip phenomenon. Irregular stretching occurs depending on the strength and weakness of the gripping points.

In this stretching process, friction occurs due to slip between the wool fibers, so that the tip portion of the scale is partially destroyed or slowed, and the interval between the scales is largely relaxed, thereby providing excellent anti-shrinkage effect to the simulation.

In the process of shrinking the stretched wool, the fully stretched wool fiber is not shrunk to its original length, but the less stretched wool fiber is shrunk to its original state, thereby providing thermal plasticity as the fiber fiber.

Due to this difference in thermoplasticity, the woolen yarn reaches a high bulky state, resulting in high voluminous feel and excellent touch.

Wetting and relaxing the simulated yarns to the original length or less can make the high bulky phenomenon more prominent, and better simulate the warmth and moisturizing properties.

Example 1

The resultant was obtained by increasing the number of 10 wool 2 yarns of woolen wool yarn to the optimum stretching temperature in the pressure resistant tank and stretching it at 1.5 times, then rapidly lowering the temperature in the tank to below 100 ℃ and then wet-relaxing for 15 minutes in the tensionless state. It has been found that the surface area of the yarn has been expanded and the touch and anti-shrinkage effects have been excellent due to the high bulk state.

I.W.S. in the flat knitting machine of 6 gauges based on this processing simulation. According to TM 31, the felt shrinkage test was performed and the result showed that the felt shrinkage area was 6.9%. (In the case of normal simulation, the felt shrinkage area is 35% to 45%)

Figure 2 (b) is an enlarged photograph of the wool fibers of the processing simulation according to the present invention, it can be seen that the scale of the surface is greatly slowed down and relaxed, the contact state of the wool fibers illustrated in Figure 3 (b) It is easy to see that the anti-shrink effect is excellent because it is not engaged.

Claims (1)

Hank-like woolen or wool blended yarns are held in a pair of rollers in a pressure-resistant tank, stretched to the stretching limit while maintaining the optimum stretching temperature, and then contracted to their original length under tension, and then wetted for 15 minutes at a temperature below 100 ℃. Processing method of the simulation for imparting a contractility and a sense of volatility characterized by processing.
