Description

Method for manufacturing coconut fiber mat using corn fiber as screening {METHOD FOR MAKING COCONUT MAT}

The present invention relates to a method for providing a coconut mat using natural threads extracted from corn as core yarn.

The present invention relates to a method for providing a coconut mat using natural threads extracted from corn as core yarn. Coconut mat, also known as palm mat, is used to prevent slipping by placing it in front of the front door or laying it on the road to prevent slipping on mountain roads, swimming pools, and golf courses. 1 shows a photograph of a coconut mat used for this purpose. Before coconut mats were used, concrete, rubber chips, waste tires, etc. were buried and used. In the case of using these materials, when it rains heavily, materials such as waste tires are separated from the pavement and the pavement is dented or rainwater accumulates. The roads were often more messy, and since the material itself is not environmentally friendly, harmful substances such as endocrine disruptors are generated when exposed to sunlight or moisture for a long time, which not only adversely affects users but also the environment. I don't know if I personally use it because it ruins it, but it started to be removed from the mountain trail. In addition, when these materials are used, there is a disadvantage in that they must be dried over a long period of time after applying these materials to trails or hiking trails. So recently, because of the disadvantages of these materials, mats made using coconuts that can be installed quickly are used a lot.

Coconut mats are used in various fields because they cost less than construction, and can be removed immediately when not needed and can be replaced at any time. Recently, it is also used to prevent the slope from collapsing by attaching it to the slope of a mountain, or to sow seeds on a coconut mat so that plant roots can be established within the mat. The method of providing such a mat can be manufactured in various ways depending on the purpose, but the most used method is to provide a screening and then wrap the coconut fiber around the screening, using a thick rope woven by weaving it horizontally and vertically again. to weave a mat However, although coconut fiber is tough and strong, it is very difficult to weave it into a rope form because the unit length is very small. In particular, in the case of using natural yarn, since the natural yarn serving as the inner core is easily broken by the coconut fiber covering the outside, synthetic fibers such as nylon, not natural yarn, are used for screening.

In other words, coconut mats are introduced as natural mats and are sold, but synthetic fibers are used for screening, so when discarding, they must be separately collected and disposed of. Coconut mats are often laid on every hiking trail, but synthetic fibers are used If not, it can be disposed of by landfilling as it is, depending on the place, and when discarded, it can completely rot and disappear within about 120 days, but since synthetic fibers are used, it cannot be disposed of as it is.

Republic of Korea Patent Registration No. 10-1670009 Vegetation mat for suppressing weed germination and its construction method include a non-woven fabric layer and non-woven fabric layer that prevent soil loss and preserve soil moisture, and an epidermis that decomposes according to external environmental conditions And it can perform the function of keeping warm and moisturizing from the cold temperature outside on the upper part of the non-woven fabric layer, and a layer was formed using vegetable materials such as rice straw, palm leaves, and coconut shells. In order to use it as a vegetation mat, several layers Although it is configured, it is not woven vertically and horizontally in the form of a mat, but it is formed so that it is attached to the non-woven fabric layer, so the strength and durability are lowered.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a natural mat that can be disposed of by landfilling as it is using natural fibers as a core.

In order to achieve the above object, there is provided a method for manufacturing a coconut fiber mat using corn fiber as a core. A second step of making a coconut rope by providing the coconut fibers produced in the step to be wrapped around to rotate and twisted together; It includes a third step of making a mat by weaving the coconut ropes made in the second step vertically and horizontally. it could be

The inner core may be left-twisted with two strands of yarn worked with a lower twist of 600 to 700TM and an upper twist of 580 to 630TM, and then plied by chance using two strands of 380 to 480TM.

The core may have been left-twisted with two strands using yarn worked with lower yarn 680 TM and upper yarn 600 TM, and then 460TM and 380TM yarns were accidentally plied here.

By the configuration as described above, it has the effect of providing a mat that can be easily decomposed by providing a natural coconut mat with corn fiber as the core.

Figure 2 is a view showing a manufacturing process according to the present invention

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The mat according to the present invention includes the steps of providing coconut fibers, providing corn fibers, forming a rope using coconut fibers and corn fibers, and providing a mat.

In order to manufacture coconut mats, priority should be given to providing corn fibers used as screening. In order to improve the durability of corn fibers rather than 100% natural corn fibers, when other synthetic fibers including polyester fibers are spliced together, it is no different from using nylon as a screening because the screening does not rot easily. That is, the most important thing is whether it is possible to provide natural fibers having enough strength to be used for screening. It provides corn fiber that can be used as

First of all, corn leaves, husks, grains, and whiskers, which are raw materials, are prepared and fiber is extracted. There are many known methods for producing corn fiber, but the step of mixing conventionally used corn fiber with synthetic fibers such as polyester fiber and rayon was essential, and this was to secure durability against tension. Corn fiber is not irritating to the skin and has been widely used in clothing, toys, and bedding. Other natural materials other than corn fiber can be used as screening, but many other natural materials do not satisfy the durability against tension, and many of them are difficult to process enough to be used as screening, apart from durability. Even if only coconut fiber goes through several twisting processes, it is difficult to process enough to be used as screening, so fibers other than coconut fiber are used separately.

In order to extract fiber, corn leaves, husks, grains, and beard, which are raw materials, are crushed and washed. The washing may include a process of removing foreign substances, and may include a method of rotating the roller to remove the foreign substances and giving continuous impact so that the foreign substances fall off, or a method of centrifugation. The foreign matter removal step may take several steps because it affects the quality of the yarn to be manufactured.

Corn raw materials that have been washed go through a carding process similar to the normal yarn manufacturing process. It is made into slivers, which are fiber aggregates in the form of thick and long ropes, by regularly arranging fibers that have been pulverized but are aggregated without directionality. Since the fiber density of the sliver is different for each location, it goes through a twisting process while going through a plying process in which several slivers are combined. Through this process, the corn fiber is equipped with a fiber shape having a certain density and thickness. If necessary, go through several times of plying to achieve the desired thickness and density.

The fibers that have undergone the plying process are combed to remove various foreign substances and short fibers that still remain in the fibers through the combing process. The combing process removes these foreign substances and short fibers through the same process as combing. . Short fibers are short fibers of less than 1 inch and are not suitable for actual fabrication, and when mixed, the strength of the yarn is reduced. The yarn that has gone through the process of regular cotton can go through a drawing process in which several strands are combined and stretched thin.

The yarn that has gone through the drawing process goes through the roving process to prevent breakage by twisting the yarn. The twist given in the roving process is minimal, and the strength of the yarn is increased by giving the necessary twist to the yarn through the spinning process. The yarn is composed of short fiber aggregates, which stretches the sliver and gives it strength by twisting it at the same time. In particular, depending on how much twist is given, the thickness of the thread changes and the strength changes. In addition, there is a difference in the use of the yarn depending on the degree of twist, but in the case of natural fibers, since there is a limit to give twist, it cannot have more than a certain amount of strength.

In the present invention, in order to have strength that can replace nylon, natural materials are used to provide fibers that can be used as cores, but synthetic fibers are not used while overcoming the disadvantages of natural fibers in strength. Even if it is twisted to give proper strength to make it easy to dispose of, since there is a limit to twisting in the case of natural fibers, two fibers manufactured in different shapes are plied and used.

To this end, left-twisting is done with two strands using yarn worked with 680 TM for the lower yarn and 600 TM for the upper yarn, and then, 460TM and 380TM yarns are used for coincidence plying again. Threads that are plied under other conditions may maintain some strength, but as a result of several experiments, it is very difficult to produce a thread that can be used with a suitable screening for rope making using coconut, and it is very difficult to make it with natural fibers, even with corn fibers. This was possible only under the above conditions.

Roughly, two strands of yarn with a lower twist of 600 to 700TM and an upper twist of 580 to 630TM are left-twisted, and two strands of 380 to 480TM are used for coincidence. It is difficult to work to 700TM to make corn fiber, and yarns of 380TM or less have less twist and are easy to break when used, and when the above combination is made, it maintains enough strength to be used as a core.

Coconut fiber rope is manufactured by winding the coconut yarn around the core from the outside using the fiber produced in this way as a core, and a mat is manufactured by using the coconut fiber rope thus prepared as warp and weft. Since providing a core to produce a coconut fiber rope is already known, detailed descriptions will be omitted.

The following are the average values obtained after measuring the tensile strength and elongation of the fiber (Example 1) prepared in the above manner, nylon used in coconut fiber (Comparative Example 1), and 700TM corn fiber (Comparative Example 2) 50 times. .

Tensile strength (g/denier) Confidence (%) Example 1 3.6 6.5 Comparative Example 1 3.9 14.5 Comparative Example 2 2.7 11.2

Tensile strength was expressed as g/denier by the load at which the fiber was cut, and the elongation rate (elongation) was expressed in % as elongation. Although the tensile strength of Example 1 is lower than that of nylon, it can be seen that the tensile strength is considerably improved compared to the fiber before plying as a natural fiber. The elongation depends on the characteristics of the fiber, but it does not increase much compared to nylon, and the reduction in elongation by plying can be of great help in making coconut fiber.

The tensile strength for use as a screening of coconut fiber is found to be approximately 3.4 or more, and elongation is not a big problem, but as low as possible helps to maintain the original shape. The tensile strength of Example 1 is 3 or 6, which can be used as screening of coconut fiber. However, in the case of Comparative Example 2, the tensile strength is only 2.7, so it is often broken when used as a test.

In the following table, the fibers of Example 1, Comparative Example 1, and Comparative Example 2 were buried 1 meter deep in the ground, and the weight of the remaining amount remaining intact after 45 days and 60 days was measured and compared.

45 days after 60 days Example 1 40.1% 10.3% Comparative Example 1 99.9% 99.9% Comparative Example 2 39.8% 10.4%

It can be seen that Example 1 and Comparative Example 2 are rotting to a similar extent, and Comparative Example 1, which is a nylon fiber, is not rotting in the ground at all.
