Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band interlining for kimono and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, Japanese obi belts are made by laying cotton on the surface of the belt interlining in order to improve the adhesion between the belt and the interlining and prevent slippage during use. A method of weaving a silk thread in a floating tissue to the tissue, cutting and raising the floating portion of the silk thread, and preventing deviation due to the fluff generated by the raising (see Japanese Patent Laid-Open No. 58-15624), cotton and other plant fibers. The warp is a yarn made of, and the silk yarn of the woven fabric is made of a weft made of a silk fiber.
Although a method of preventing deviation due to fluff generated by raised hair has been proposed (see Japanese Patent Application Laid-Open No. 1-231907), the method of laying down cotton requires skill to perform the work, and the method of raising the fabric has a high manufacturing cost. In any case, since the woven fabric has been used, there is a problem that the texture is hard.

Therefore, in order to soften the texture, what is called a flat cocoon (a cocoon thread discharged from a mature silkworm in a flat shape) has also been used (see JP-A-56-159337). However, it is far from an industrial non-woven fabric, and is rather suitable as a craft product, and there is a problem that it is not possible to prevent a shift during use with a belt without raising one side. That is, since it is difficult to produce a nonwoven fabric in which silk fibers are the constituent fibers and the constituent fibers are evenly distributed over the entire sheet, only such crafts are used, and thus the silk fibers are the constituent fibers. The fact is that high-quality non-woven fabrics have not been provided yet.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is made of a silk non-woven fabric having a high-grade feeling, which has high adhesiveness to the web and is soft and highly uniform. The purpose is to provide. Another object of the present invention is to provide a method capable of easily and inexpensively producing such a band interlining.

[0005]

The above-mentioned object is a non-woven fabric in which short silk fibers are entangled with each other by the action of a high-pressure water flow, and the surface of the non-woven fabric is MI by the KES method.
This is achieved by a band interlining material having a U value of 0.1 or more.

The present invention will be described in detail below.

In the present invention, the raw materials of the silk short fibers constituting the non-woven fabric include Japanese, Chinese, Soviet, Indian,
It may be from any production source such as South Korea, or may be obtained from either a domestic silkworm that is normally bred or a wild silkworm that is wild. What is important in the present invention is that such short silk fibers are entangled with each other by the action of a high-pressure water stream to form a nonwoven fabric. This is because the short silk fibers are not fibrillated by the needle punch method, the binder method, the heat fusion method and the like, and the surface characteristics described below cannot be obtained.

It is necessary that such a nonwoven fabric has an MIU value of 0.1 or more according to the KES method. When the MIU value by the KES method is less than 0.1, the average friction coefficient of the nonwoven fabric surface is small and smooth, and when a nonwoven fabric having such surface characteristics is used as the band interlining, the adhesiveness between the band and the interlining is Is low, and the occurrence of misalignment is observed during use. K
ES system is KAWABATA EVALUATION
It is an abbreviation for SYSTEM and an evaluation method devised by Professor Kawabata of Kyoto University. Here, the MIU value according to the KES method is a value calculated by the following formula.

[Equation 1] However, μ = friction force / force to press the sample χ; position on the sample surface X; moving distance (here, 2 cm) That is, in the present invention, the MIU value according to the KES method is selected by selecting the confounding condition by the high-pressure water flow. It is essential that the value be 0.1 or more.

In the banding material of the present invention, the residual sericin of the silk sliver is scoured to 5% or less, the silk sliver is cut in the range of 30 to 75 mm, and then carded to form a web. After that, it is manufactured by a method for manufacturing a band interlining, which is characterized in that it is entangled with a high-pressure water stream.

The short silk fibers constituting the silk sliver used in the present invention preferably have a fiber length of 100 mm or more because a uniform web can be obtained when carded. Further, it is preferable to use one having a fineness of about 1 denier and less variation, because a nonwoven fabric which is stable by hydroentanglement described below can be obtained.

The scouring referred to in the present invention is not particularly limited, and for example, an anion activator such as soap, higher alcohol detergent, soapless soap and the like and a relatively weak alkali such as sodium carbonate, sodium bicarbonate or sodium silicate are used in combination. There is a method. In such scouring, it is important that the residual sericin is 5% or less, preferably 1% or less. If the residual sericin content exceeds 5%, it is not preferable because it exhibits conjugation properties for carding and a uniform web cannot be obtained when carded.

The refined silk sliver is then cut with a cut length of 30 to 75 mm, preferably 50 to 70.
It is important to set to mm. That is, if the cut length is out of the above range, a uniform web cannot be obtained when carded. The silk short fibers thus obtained are carded into a web.

The web-shaped silk fibers are then entangled with a high-pressure water stream to form a nonwoven fabric. A method of entanglement of fibers with a high-pressure water flow is described in U.S. Pat. No. 3,485,706. For example, to entangle silk fibers, a hydraulic entanglement device manufactured by Perhojet is used. The water pressure varies depending on the nozzle shape and the number of nozzles, but it is 80 to 250 kg / cm.
^{About 3} is preferable. After being entangled with water pressure, pressurized air,
Dry under vacuum, heat, pressure, etc.
