Kapok-Fiber Finshing Method For Improving Spinning Property}

The present invention relates to a processing method of kapok fiber for improving the spinning property by greatly increasing the weight of kapok fiber, which is a super lightweight and natural hollow fiber.

Kapok fibers are obtained from the arboretum of 10-15 m in height. Its shape is different from that of cotton and its length is 10 ~ 15cm, and its central diameter is 4 ~ 6cm radial. When the stalk matures, it spontaneously opens up, and fibers grow from the inside. Cotton grows by itself, but kapok grows when the wind blows, with seeds attached, when the wind blows. Seeds are considerably smaller and more red than cotton seeds, and can be easily separated from the seeds and fibers simply by tapping them, eliminating the hassle of cotton.

The length of kapok fiber is generally 18 ~ 27mm, the diameter is about 0.02mm and the inside of the fiber is completely hollow.

It is strong enough to withstand the penetration of water, rich in flammability, and capable of floating about 35 times its own weight. It is also used as a filling material for life-saving equipments because of its ability to lift 26 times the weight even after one month of immersion. In addition, it is used instead of pillow or duvet cotton because of its light, elasticity and warmth.

By using these characteristics, there is a demand for the commercialization of ultra-light and heat-retaining kapok fiber. However, kapok fiber has no property of tangling compared to cotton fiber and its strength is relatively weak, so it cannot be spun alone. In the case of use, the fiber is broken and the plane state is lost and the problem of being firmly entangled occurs. Thus, even when a mixed yarn is made, it is difficult to achieve uniform strength and uniformity.

In particular, when the kapok fiber is manufactured with a yarn, the specific gravity is lower than that of the general cotton fiber is scattered during the spinning process, there is a problem that the spinning property is not good and harm the working environment.

The present invention for solving the above problems is to provide a processing method of the kapok fiber that can increase the weight of the kapok fiber to prevent the kapok fiber is scattered during spinning to greatly improve the spinning properties and working environment It is done.

The present invention for achieving the above object,

It provides a processing method of kapok fiber for improving the spinning property, comprising the step of treating the kapok fiber in water containing 2 to 5% by weight of the quaternary ammonium compound as an extender.

In addition, it is preferable to dry the kapok fiber treated with the extender for 2 to 4 hours at a temperature of 40 ~ 60 ℃.

Hereinafter, the processing method of the kapok fiber for improving the spinning property of the present invention will be described in detail.

The processing method of the kapok fiber of the present invention comprises a step of treating the kapok fiber with an extender and then drying.

The extender is intended to increase the weight of kapok fibers, using quaternary ammonium compounds.

The extender is mixed (dissolved) in water to treat the kapok fibers. At this time, the extender is preferably mixed with 2 to 5% by weight in water. When mixing less than 2% by weight, the increase in the weight of the kapok fiber is insufficient to scatter when spun, when mixed with more than 5% by weight accumulates in the fiber to cause a yellowing phenomenon.

And the kapok fiber treated to the extender is dried. In order to maximize the increasing effect of the processed kapok fiber, it is preferable to dry at 40 to 60 ° C. after the increase processing agent treatment.

It is preferable to dry the increased kapok fiber at the lowest possible temperature, and the increase in the drying temperature increases the possibility of yellowing of the kapok fiber. In addition, the longer the drying time, the higher the probability of damaging the kapok fiber due to the temperature, and the effect of the increase processing is also reduced, so it is desirable to treat it at the lowest possible temperature and drying time. The drying temperature is preferably 40 ~ 60 ℃ slightly higher than the room temperature, using a vacuum dryer can improve the drying effect. The drying time is preferably about 2 hours to 4 hours, and the time is preferably adjusted according to the amount of kapok fibers to be dried.

The processing method of the kapok fiber of the present invention can greatly increase the weight of the kapok fiber, it is possible to prevent the kapok fiber from scattering during spinning, such as to greatly improve the spinning properties.

Hereinafter, the processing method of the kapok fiber for improving the spinning property of the present invention will be described in more detail with reference to the following Examples, the scope of the present invention is not limited to the following examples.

Example 1

10 g of kapok fiber was immersed in 50 ml of water mixed with 2% by weight of the extender, and dried at 50 ° C. for 3 hours using a vacuum oven to obtain the weight-treated kapok fiber of Example 1. At this time, quaternary ammonium was used as the extender, and the kapok fiber had a fiber length of 25 mm and an average fiber diameter of 0.026 mm.

EXAMPLES 2-5

Unlike Example 1, the processed kapok fibers of Examples 2 to 5 were treated and dried by immersing the kapok fibers in 50 ml of water containing 1% by weight, 3% by weight, 5% by weight, and 7% by weight of the extender. Got.

[Examples 6 to 9]

Unlike Example 1, the kapok fiber treated with the increased weight was dried for 3 hours using a vacuum oven adjusted to 30 ° C, 40 ° C, 60 ° C and 70 ° C for 3 hours, and then the weighted kapok fiber of Examples 6-9. Got.

[Examples 10-13]

Unlike Example 1, the kapok fiber treated with the extender was dried at 50 ° C. for 1 hour, 2 hours, 4 hours, and 5 hours using a vacuum oven to obtain the weight processed kapok fibers of Examples 10 to 13.

The weight and fiber condition of the kapok fiber processed by the weight of Examples 1 to 13 thus prepared and measured, and the results are shown in Table 1 below.

As can be seen from the increase ratio and fiber state of the weight processed kapok fiber of Table 1, all of Examples 1 to 13 were increased by 8% or more, and the fiber state was all good. In particular, in the case of Example 2 in which 1% by weight of the extender was mixed, the increase ratio was insignificant to 8%, while in Examples 1 and 3 to 13, in which 2 to 5% by weight of the extender was mixed, the increase ratio was 12.0% or more. There is an advantage that the spinning property is improved. In Example 5, the increase ratio was high as 14.2%, but yellowing partially occurred.
