Abstract
An elastic fiber for a chair is composed of a core layer and a surface layer formed in a co-extrusion method. The core layer and the surface layer are same serial elastic materials, Thermalplastic Ester Elastomer (TPEE). The core layer has a higher melting point than that of the surface layer. The ratio of the core layer to the surface layer is 9:1, 8:2 or 7:3.
Description
- 1. Field of the Invention
- The present invention relates to an elastic fiber for a chair, in particular to an elastic fiber composed of a core layer and a surface layer formed in a co-extrusion method. The core layer has a higher melting point than that of the surface layer.
- 2. Description of the Prior Art
- Conventional fibers, such as U.S. Pat. Nos. 5,677,057 and 5,858,528, comprise a core layer and a surface layer made of different materials having different melting points in a co-extrusion method. This co-extrusion method is to melt and to conjugate the core and the surface layers together. However, the core layer and the surface layer made of different materials have different coefficients of elasticity, causing different deformation speeds. In the beginning, the peeling is slight, but after a period of time the peeling will become serious. Fatigue will eventually affect the material, and it starts to deterioration.
- If this material is used as a chair cloth, the surface tension will restore in a rapid speed at the beginning. However, after a period of time, the cloth will lose its elastic character because of the peeling of the core layer and the surface layer.
- According to the present invention, there is provided an elastic fiber comprising a core layer and a surface layer formed in a co-extrusion method. The core layer and the surface layer are same serial elastic materials, Thermalplastic Ester Elastomer (TPEE). The core layer has a higher melting point than that of the surface layer. The ratio of the core layer to the surface layer is 9:1, 8:2 or 7:3.
- The present invention provides the following advantages:
- 1. Having a longer life span;
- 2. Restoring its shape at a fast speed

FIG. 2 is a cross sectional view of a second embodiment of the present invention; -
FIG. 3 is a cross sectional view showing a heat-bonding connection of the first embodiment of the present invention; -
FIG. 4 is a cross sectional view showing a heat-bonding connection of the second embodiment of the present invention; and -
FIG. 5 is top view of an elastic cloth woven with the elastic fibers of the present invention. - As shown in
FIG. 1 , a first embodiment of the present invention comprises anelastic fiber 1 composed of acore layer 11 and asurface layer 12 formed in a co-extrusion method. Thecore layer 11 and thesurface layer 12 are same serial elastic materials, such as Thermalplastic Ester Elastomer (TPEE). Thecore layer 11 has a higher melting point than that of thesurface layer 12. The ratio of thecore layer 11 to thesurface layer 12 is 9:1, 8:2 or 7:3. - As shown in
FIG. 3 , when doing the heat-bonding process, the lower melting point of thesurface layer 12 makes it easy to conjugate with thecore layer 11. Thecore layer 11 having a higher melting point is harder than thesurface layer 12, which produces a higher tension against a pulling force. Thesurface layer 12 is less hard and is easy to deform when a pulling force is applied. A number of theelastic fibers 1 may be wrung to become one elastic string, which is then applied with heat to conjugate theelastic fibers 1 together. The elastic string may be woven to an elastic cloth, and then do the heat-bonding process. - As shown in
FIG. 2 , a second embodiment of the present invention comprises anelastic fiber 1A composed of acore layer 11A and asurface layer 12A formed in a co-extrusion method. As shown inFIG. 4 , thecore layer 11A and thesurface layer 12A are same serial elastic materials, such as Thermalplastic Ester Elastomer (TPEE). Thecore layer 11A has a higher melting point than that of thesurface layer 12A. The ratio of thecore layer 11A to thesurface layer 12A is 9:1, 8:2 or 7:3. -
