Description

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

The present invention relates to a method of providing a coconut mat using natural thread extracted from corn as the core.

The present invention relates to a method of providing a coconut mat with natural thread extracted from corn as the core. Coconut mats are also called coconut mats and are placed in front of the entrance to prevent slipping, or are used on mountain paths, swimming pools, golf courses, etc. to keep them from slipping. Figure 1 shows a photograph of a coconut mat used for this purpose. Before using coconut mats, concrete, rubber chips, waste tires, etc. were used as landfills. However, when these materials are used and there is a lot of rain, materials such as waste tires are separated from the pavement, causing dents in the pavement or accumulation of rainwater. The roads often became more messy, and the materials themselves are not eco-friendly, so when exposed to sunlight or moisture over a long period of time, harmful substances such as environmental hormones are generated, which not only has a negative impact on users but also the environment. I don't know if you use it personally because it ruins the weather, but it is starting to be removed from hiking trails. Additionally, when using these materials, there was a disadvantage that they had to be dried over a long period of time after being applied to a walking or hiking trail. So recently, due to the shortcomings of these materials, many people use mats made from coconut, which can be installed quickly.

Coconut mats are used in a variety of fields because not only are they less expensive than construction, but they can be removed immediately when not needed and can be replaced at any time. Recently, it is also used to attach to the slope of a mountain to prevent the slope from collapsing, or to sow seeds on a coconut mat so that plant roots can grow into the mat. These mats can be manufactured in a variety of ways depending on the purpose, but the most commonly used method is to provide a screen and then re-weave it horizontally and vertically using a thick rope woven by wrapping coconut fiber around the screen. Weave a mat. However, although coconut fiber is tough and strong, its unit length is very small, so it is very difficult to weave it into a rope. In particular, when using natural yarn, the natural yarn that forms the core is easily broken by the coconut fiber surrounding the outside, so synthetic fibers such as nylon are used as the core instead of natural yarn.

In other words, coconut mats are introduced and sold as natural mats, but because they use synthetic fibers for screening, they must be collected and disposed of separately. Coconut mats are often laid out on hiking trails, but synthetic fibers are used. If not, depending on the location, it may be landfilled and disposed of as is. Once disposed of, it may completely rot and disappear within about 120 days, but since synthetic fibers are used, it cannot be disposed of as is.

Republic of Korea Patent Registration No. 10-1670009 Vegetation mat for suppressing weed germination and its construction method includes a non-woven fabric layer that prevents soil loss and preserves soil moisture, and a surface layer that decomposes depending on external environmental conditions. A layer has been formed on the upper part of the fabric layer using plant materials such as rice straw, palm leaves, and coconut shells, which can perform the function of insulating and moisturizing from the cold temperature outside. In order to use it as a vegetation mat, it is divided into several layers. Although it is constructed, it is not woven horizontally and vertically in a mat-like form, but is attached on top of the additional fabric layer, which reduces its strength and durability.

The present invention was developed to solve the problems described above, and its purpose is to provide a natural mat that uses natural fibers as a core and can be disposed of by landfill.

In order to achieve the above-described purpose, a method of manufacturing a coconut fiber mat using corn fiber as a core is provided. The first step is to cut the coconut shell into small pieces to make a coconut fiber body, and the first step is to make a coconut fiber body around a core made of natural fiber. A second step of making a coconut rope by providing the coconut fibers prepared in the step, wrapping them to rotate, and twisting them together; It includes the third step of making a mat by weaving the coconut ropes made in the second step horizontally and vertically. The core made of natural fiber is made by twisting two strands of corn fiber into a twisted twist and twisting two strands of corn fiber by chance. It may be.

The core may be made by twisting two strands of yarn with a lower yarn of 600 to 700 TM and an upper yarn of 580 to 630 TM, and then accidentally plying them with two strands of 380 to 480 TM yarn.

The inner core may have been twisted into two strands using yarn made with a lower yarn of 680 TM and an upper yarn of 600 TM, and then 460 TM and 380 TM yarn were accidentally twisted here.

The above-mentioned configuration has the effect of providing a natural coconut mat with a core made of corn fiber, thereby providing an easily decomposable mat.

1 is a diagram showing an example of use of a coconut mat.
Figure 2 is a diagram showing the manufacturing process according to the present invention.

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

To manufacture coconut mats, priority should be given to providing corn fibers that are used as screening. If other synthetic fibers, including polyester fibers, are spun together to improve the durability of corn fiber rather than 100% natural corn fiber, the core does not rot easily, making it no different from using nylon as the core. In other words, the most important issue is whether natural fibers with enough strength to be used for screening can be provided, and in the present invention, screening is conducted through a method of twisting and plying corn fibers made from corn husk and corn silk. Provides corn fiber that can be used as a

First, the raw materials such as corn leaves, husks, kernels, and silk are prepared and the fiber is extracted. There are many known methods of producing corn fiber, but the step of mixing corn fiber with existing synthetic fibers such as polyester fiber and rayon was essential to ensure durability against tension. Corn fiber does not irritate the skin, so it has been widely used in clothing, toys, and bedding. Other natural materials other than corn fiber can be used as a fiber, but many other natural materials do not satisfy durability against tension, and many of them are difficult to process to the extent that they can be used as a fiber, regardless of durability issues. Because it is difficult to process coconut fiber enough to use it as a fiber even if it goes through several twisting processes, fibers other than coconut fiber are used separately.

To extract fiber, the leaves, husk, kernels, and silk of corn are crushed and washed. Cleaning may include a process of removing foreign substances. To remove foreign substances, it may include a method of rotating on a roller and continuously impacting to remove foreign substances, or centrifuging. The foreign matter removal step can go through several stages because it affects the quality of the yarn being manufactured.

After washing, the corn raw material goes through a carding process similar to the ordinary yarn manufacturing process. The pulverized but unoriented fibers are arranged in a regular manner to create sliver, a thick, long rope-like fiber aggregate. Since the density of the sliver fibers varies depending on the location, it goes through a twisting process that combines several slivers. Through this process, corn fibers take the form of fibers with a certain density and thickness. If necessary, go through several braiding processes to achieve the desired thickness and density.

Fibers that have gone through the braiding process are subjected to a grinding process to remove various foreign substances and very short short fibers still remaining in the fiber. The grinding process removes these foreign substances and short fibers through a process similar to combing. . Short fibers are short fibers of less than 1 inch and are not suitable for actual yarn, and when mixed, they reduce the strength of the yarn. Yarn that has gone through the milling process can go through a drawing process in which several strands are joined and stretched thinly.

The yarn that has gone through the drawing process goes through a roving process, which adds twist to the yarn to prevent it from breaking. 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. Yarn is made up of a collection of short fibers, which stretches the sliver and twists it at the same time to give it strength. In particular, depending on how much twist is given, the thickness of the yarn changes and its strength changes. In addition, there are differences in the uses of the yarn depending on the degree of twist. However, in the case of natural fibers, there is a limit to the amount of twist that can be applied, so they may not have strength beyond a certain level.

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, and while overcoming the disadvantages of natural fibers in strength, they are used without using synthetic fibers. Even though twisting is used to provide appropriate strength to make it easy to dispose of, natural fibers have limitations in twisting, so they are used by braiding two fibers made in different shapes.

For this purpose, two strands are twisted together using yarn made with 680 TM lower and 600 TM upper yarns, and then the yarn is twisted again using 460 TM and 380 TM yarns. Yarn that is plaited under different conditions may maintain some strength, but as a result of numerous experiments, it has been found that it is very difficult to make yarn that is suitable for use in making ropes using coconuts from natural fibers, and corn fibers are also used. This was possible only under the above conditions.

Roughly, the yarn worked with the lower yarn 600 to 700 TM and the upper yarn 580 to 630 TM is left twisted into two strands, and then two strands of 380 to 480 TM yarn are used to ply the yarn by chance. To make corn fiber, it is difficult to work it to 700TM, and threads below 380TM have little twist and are easy to break when used. When the above combination is used, the strength is maintained enough to be used as a core.

A coconut fiber rope is manufactured by using the fiber manufactured in this way as the core and winding coconut thread from the outside around the core, and a mat is manufactured using the coconut fiber rope manufactured in this way as warp and weft. Since manufacturing a coconut fiber rope by providing a core is already known, a detailed description is omitted.

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

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

Tensile strength is the load at which the fiber is cut, expressed in g/denier, and the elongation rate (degree of stretching) is called elongation and expressed in %. Example 1 has a lower tensile strength compared to nylon, but it can be seen that the tensile strength is significantly improved compared to the fiber before plying as a natural fiber. Elongation varies depending on the characteristics of the fiber, but it does not stretch much compared to nylon, and the fact that the elongation is reduced by plying can be greatly helpful when used in the production of coconut fiber.

The tensile strength for use as a screening test for coconut fiber is estimated to be approximately 3.4 or higher. Elongation is not a major problem, but keeping it as low as possible helps maintain its original shape. The tensile strength of Example 1 was 3.6, which is sufficient to be used as a screening material for coconut fiber. However, in the case of Comparative Example 2, the tensile strength was only 2.7, so there were many cases of breakage when used for screening.

The following table compares the fibers of Example 1, Comparative Example 1, and Comparative Example 2 by burying them in the ground at a depth of 1 meter and measuring the weight of the remaining amount remaining intact after 45 and 60 days.

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

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