Problems solved by technology

In addition, the conventional insulators for construction was incinerated or buried when disposed as waste.
Especially, when a composite synthetic fiber having core sheath structure is used, core portion remains in fiber shape after the heat treatment and gets caught in the feathered fiber, increasing the aperture rate in the insulator.

Embodiment Construction

[0013] Now, embodiment of the present invention will be described based on the attached drawings. FIG. 1 shown the manufacturing process of natural feathered fiber insulator, and first, natural feathers, for instance bird plumes used for a down quilt are degreased and washed with alcohol 1. Then, after drying, they are processed into fibers of about 10 mm in length by a cutter having a screw form blade 2.

[0014] 1 to 99 weight % of feathered fiber obtained by the aforementioned fiber shape processing 2 and 1 to 99 weight % of synthetic fiber as binder are compounded, and mixed so that both fibers become uniform 3. Feathered fiber 3 compounding rate is preferable 50 to 90%, however, it may differ according to the use object of the insulator, and is not limited.

[0015] Concerning synthetic fiber as binder, a core sheath composite fiber wherein the sheath portion is made of low melting point olefin and the core portion is made of high melting point synthetic resin, for example, a core sh...

Abstract

To supply a natural feathered fiber insulator, presenting a better insulation performance than the conventional insulator, emitting less hazardous material when disposed and incinerated, being mostly biodecomposed when buried. For the manufacturing, natural feathers are degreased and washed with alcohol 1, and after drying, are processed into fiber shape 2. 1 to 99 weight % of this feathered fiber obtained as component material and 1 to 99 weight % of PP/PET core sheath composite fiber as binder are compounded, and mixed uniformly 3. The mixture is laminated to obtain a required density 4, and heat molded by a hot air dryer 5. Feathered fiber and core sheath composite fiber's core fiber get caught complexly, allowing to increase the whole aperture rate considerably. As feathered fiber is a natural organic substance, it does not emit hazardous material when incinerated, and biodecomposed if buried in the earth.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to an insulator using natural feathered fiber.[0003] 2. Detailed Description of the Prior Art[0004] The conventional insulator, for example, insulator for construction is a material useful for reducing the air-conditioning load by preventing as much as possible the thermal transfer between building inside and exterior, preventing condensation on the inner wall surface, and moreover enhancing the feeling of comfort of habitant by approaching the inner wall surface temperature to an appropriate temperature. The housing insulation has been promoted by promulgating in 1980 the Notification No. 1 of the Ministry of International Trade and Industry and Ministry of Construction and the Notification No. 195 of the Ministry of Construction, based on the stipulations of the "Act concerning the Ratification of Energy Use" as housing energy-saving criteria, and these criteria were revised in 1992, the judgment criteria were pu...
