Abstract

PROBLEM TO BE SOLVED: To provide a method for producing a kenaf yarn free from fluff in twisting kenaf fibers. SOLUTION: Funori (Japanese glue produced from a glue plant, Gloiopeltis) is applied to a fiber composed of the bast of kenaf and the fibers coated with the Funori; are twisted to form a kenaf yarn. The formation of fluffs can be suppressed by the Funori applied to the yarn.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a method for producing kenaf yarn.

[0002]

2. Description of the Related Art Kenaf is an annual plant of the genus Malvaceae belonging to the family Malvaceae native to West Africa, and is attracting attention as a non-wood pulp raw material instead of wood pulp from the viewpoint of forest protection. In addition, kenaf bast fibers are used in ropes, bags, and various fabrics. 2. Description of the Related Art Conventionally, as a method of obtaining kenaf bast fibers, a method of making the fiber alkaline and a fermentation scouring method (dub pickling method) are known. In the latter method, the bast of kenaf is immersed in water and fiberized by the action of microorganisms.

[0003]

The latter method is described in detail. A soft kenaf having a thickness of about 1.5 cm and having a thickness of about 1.5 cm, which has been grown for two to three months, is collected without being replaced. Soak for 7 to 10 days (dob soak). When the kenaf is fermented by this soy pickling and becomes fermented and emits an odor, replace it with clean water. Then, the swollen bast epidermis is squeezed to remove only the bast, leaving the bast alone, immersed in fresh water and washed, and the washed bast is bundled and dried.

[0004] The dried bast is formed into a fiber by the above-described treatment, and a yarn is formed from the fiber. In the process of soaking, the skin of the bast is squeezed and the bast is colored. I do. When the fuzzy fiber is twisted into a yarn, the yarn remains fuzzy, and when the yarn is used to produce a woven fabric, the woven fabric remains fuzzy.

[0005] When the fibers are old and colored, the bast boiled in water is washed with water to remove the epidermis and impurities, prepared into individual fibers, and dried naturally to obtain dried fibers.
Also in this case, the fluff could not be avoided.
The present invention proposes a method for producing the kenaf yarn that does not generate fluff.

[0006]

Means for Solving the Problems A yarn is produced by applying a cloth to kenaf bast fiber and twisting the fiber coated with the cloth. The application of the furon prevents the yarn produced from fuzzing.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a method for obtaining kenaf fibers from kenaf bast will be described. A soft kenaf having a thickness of about 1.5 cm and having a thickness of about 1.5 cm, which has been grown for 2 to 3 months, is immersed in water for 7 to 10 days without replacing the water (dub pickling is performed). When the kenaf is fermented and soaked by this soaked pickle and emits an odor, cleanly replace it with water. Then, the swollen bast epidermis is squeezed to remove only the bast, leaving the bast alone, immersed in fresh water and washed, and the washed bast is bundled and dried. This is no different from the conventional method. afterwards,
The bast is arranged into fibers one by one and air-dried to obtain dried fibers. When the fibers are old and colored, the bast boiled in water is washed with water to remove the epidermis and impurities, and the fibers are adjusted into individual fibers, and dried naturally to obtain dried fibers.

Next, a method of obtaining a yarn without fluff from the fiber will be described. It was found that when the kenaf fiber obtained by the above-mentioned soaked pickling and the kenaf fiber obtained by the above-mentioned boiled water method were applied with twist and twisted, a yarn without fuzzing was obtained. Thus, a yarn that does not generate fluff when twisted by attaching a furrow to the fiber could be obtained.

[0009] Here, when applying the above-mentioned cloth to the fiber,
When the cotton-like lint generated when twisting the yarn was attached to the fiber or wound and twisted, a soft yarn was obtained.

[0010]

According to the method for producing a kenaf fiber yarn of the present invention, a yarn having no fluff due to attachment of a furrow can be produced.
