, Description:FIELD OF INVENTION
The current invention relates to compositions and methods for making a high-quality fiber from root of vetiver plant. This invention encompasses high quality fiber made from vetiver root, and methods and compositions for making these fibers.
BACKGROUND
Vetiver (Chrysopogon zizanioides, previously Vetiveria zizanioides) is a perennial grass and native to India. Vetiver can grow up to 1.5 meters high and form clumps as wide. The stems are tall and the leaves are long, thin, and rather rigid. Vetiver's roots grow downward, 2–4 meters in depth. Plant-based natural fibers are a major source of fibers, and are divided into bast based fibers, leaf-based fibers, fruit-based fibers and root-based fibers. Agricultural or plant-based fibers are mainly composed of different chemical component such as cellulose, hemi-cellulose, lignin, pectin and wax. Vetiver (khus) has been used for making fibers from leaves as well as roots. But these fibers are coarse, and have limited use in industries such as textiles, or textile products. Khus has aromatic and medicinal properties, but most of the times these properties are not retained during the process of making fibers from Khus.
The current invention discloses fibers made from vetiver roots, that retain fragrance and aromatic properties of Khus oil. Khus oil itself is having a lot of medicinal value specially in aroma therapy, this aroma works as a room freshener and these fibers are having cooling properties, these are natural fibers disclosed herein can be woven easily with a loom, these cool, fragrant natural fibers with medicinal values have multiple applications. Unlike the fabrics made from khus using the previously known methods, which is difficult to weave and makes bulky and inflexible products, fabric made from these fibers disclosed herein are having flexible and easy handling properties, and moreover these root fibers are having mosquito, insects and cockroaches repellent properties, with anti-depressant aroma. In short, unlike other natural fibers, these fibers do not lose its aromatic and other natural properties due to non-chemical organic method of fiber making. Thus, the current invention discloses a method of making fibers from khus root, which helps the fiber retain the properties of Khus oil (Vetiver). Moreover, the fiber is high quality, high strength, non-bulky, and can be dyed by different colors, and can be easily woven to make fabric for multiple applications.

EXAMPLES:
Example 1: Making vetiver fiber strands using cotton as second fiber to wrap the vetiver root fibers
Vetiver roots were cleaned thoroughly and all mud and dirt were removed by washing. The roots were kept in water for two days to soften them. The moist roots were used for the next step and 4-5 vertical incisions were made at the top of the root. The vertical incisions were pulled down to peel the outer part of the root. (Figs 1A-1D) . The latter steps of peeling may be required only if the root is thick. Usually, waste roots from which khus oil is extracted are very thin, or else just twisting can remove the outer shell of root and gives thin internal fiber.
After that, long thin cotton beds were prepared ( Fig. 2A) , and the root fibers were dipped in rice/ corn. Wheat / any starch solution, to get sticky surface. These thin peeled roots , dipped in sticky solution, are wrapped by twisting in cotton (Fig. 2C).

These wrapped blended fibers (cotton and vetiver and rice starch) are usually 15 to 30 centimeters long. We joined these fibers by connecting their tips with help of a thread or by simply twisting the end part of a fiber and top part of another fiber; we wrapped the thread around these fibers to increase the strength and to increase the length of the fiber. Adding two 12 inch long (30 centimeters) blended fiber will produce 24-inch long fiber and so on, by this we can get as long fiber as per requirement. These fibers are joined in an end-to end fashion (Fig. 3A-3D) by connecting tip of a blended fiber to end of another fiber so that it increase the length of the fiber, and thus vetiver blend strand is produced (Fig. 3D).
To produce fabric,
Step 1: Changes were made in handloom or powerloom to increase shutter size as the thickness of the vetiver blend strand produced by this method is more than normal thread.
Step 2: this vetiver blend strand was used for warp and waft or either warp or waft while weaving, we can make combination of this fiber with any other natural or synthetic fibers for weaving
Step 3: For making the curtains shown in Fig. 4, the weaving involved 1 waft of Vetiver Fibre + 2 waft of other synthetic or natural fiber loosely packed so that air can pass through easily
All the steps of fiber making can be done with a machine with twisting, and spinning facility. like one used for Paper rope handle making machine. in step 1 – where wrapping is needed we can use long wick making machine or a simple natural fiber rope making machine can be used, we have developed a design of machine which is a combination of all above activities and making a prototype of the same.
Example 2: Making vetiver blend fiber with recron and vetiver root fiber
Vetiver roots were cleaned thoroughly and all mud and dirt were removed by washing. The roots were kept in water for two days to soften them. The moist roots were used for the next step and 4-5 vertical incisions were made at the top of the root. The vertical incisions were pulled down to peel the outer part of the root. The latter steps of peeling may be required only if the root is thick. Usually, waste roots from which khus oil is extracted are very thin, or else just twisting can remove the outer shell of root and gives thin internal fiber.
After that, long thin recron cotton beds were prepared , and the root fibers were dipped in rice/ corn. Wheat / any starch solution, to get sticky surface. These thin peeled roots , dipped in sticky solution, are wrapped by twisting in recron cotton.

These wrapped blended fibers (recron wrapped over cotton and vetiver and rice starch) are usually 15 to 30 centimeters long. We joined these fibers by connecting their tips with help of a thread or by simply twisting the end part of a fiber and top part of another fiber; we wrapped the thread around these fibers to increase the strength and to increase the length of the fiber. Adding two 12 inch long (30 centimeters) blended fiber will produce 24-inch long fiber and so on, by this we can get as long fiber as per requirement. These fibers are joined in an end-to end fashion (Fig. 3A-3D) by connecting tip of a blended fiber to end of another fiber so that it increase the length of the fiber, and thus vetiver blend strand is produced .
To produce fabric,
Step 1: Changes were made in handloom or power loom to increase shutter size as the thickness of the vetiver blend strand produced by this method is more than normal thread
Step 2: this vetiver blend strand was used for warp and waft or either warp or waft while weaving, we can make combination of this fiber with any other natural or synthetic fibers for weaving
Step 3: For making the curtains shown in Fig. 4, the weaving involved 1 waft of Vetiver Fibre + 2 waft of other synthetic or natural fiber loosely packed so that air can pass through easily.
