A1


Abstract:
A method for manufacturing coconut based activated carbon polyester fiber with high percentage of carbon includes the steps of: mixing 5 wt %˜15 wt % (weight percentages) coconut based activated carbon particles which have sizes smaller than 7 μm with 85 wt %˜95 wt % polyester fibers by high temperature so as to get spinning fabrics which are in melted form; extruding and ejecting the spinning fabrics to pass through a fabric ejection plate so as to form a melt ejection flow; forming an initial fiber: cooling the ejection flow leaving from the fabric ejection plate in lower temperature and with a high speed to form an initial fiber; and extending, coating oil, activating, drying, shaping, and packaging to form coconut based activated carbon polyester fibers with high percentage of carbons. A coconut based activated carbon with high percentage of carbon manufactured by the method is also included.

Description:

FIELD OF THE INVENTION

The present invention relates to activated carbon polyester fiber, and particularly to a method for manufacturing coconut based activated carbon with high percentage of carbon and the coconut based activated carbon polyester fiber made by the method.

BACKGROUND OF THE INVENTION

Polyester fiber has many advantages and thus it is widely used in many fields including human life and industries.

However, in the manufacturing process of polyester fiber, many different materials are added thereto for satisfying various demands. The polyester fiber added activated carbon has high adhesion and high filtration.

In the prior art activated carbon polyester fiber, 0.1 wt %˜4 wt % (weight percentages) activated carbon particles is mixed with 96 wt % 99.1 wt % polyester fibers. However, in this prior art, the ratio of the activated carbon is very low. It cannot absorb and filer the dust in air. Thereby the sizes of the activated carbon particles are between 150 μm˜38 μm. The activated carbon cannot well adhere to the polyester fiber. Thus in washing the clothes and trousers with the activated carbon polyester fiber, the activated carbon will drop down.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a method for manufacturing coconut based activated carbon polyester fiber with high percentage of carbon and the coconut based activated carbon polyester fiber made by the method.

To achieve above objects, the present invention provides a method for manufacturing coconut based activated carbon polyester fiber with high percentage of carbon; the method includes the steps of: mixing 5 wt %˜15 wt % (weight percentages) coconut based activated carbon particles which have sizes smaller than 7 μm with 85 wt %˜95 wt % polyester fibers by high temperature so as to get spinning fabrics which are in melted form; extruding and ejecting the spinning fabrics to pass through a fabric ejection plate so as to form a melt ejection flow; forming an initial fiber: cooling the ejection flow leaving from the fabric ejection plate in lower temperature and with a high speed to form an initial fiber; and extending, coating oil, activating, drying, shaping, and packaging to form coconut based activated carbon polyester fibers with high percentage of carbons. A coconut based activated carbon with high percentage of carbon manufactured by the method is also included.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic view showing the manufacturing process of the coconut based activated carbon polyester fiber of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

Referring to FIG. 1, the manufacturing process of coconut based activated carbon polyester fiber is illustrated. The method of the present invention comprises the following steps of:

Mixing: mixing 5 wt %˜15 wt % (weight percentages) coconut based activated carbon particles which have sizes smaller than 7 μm with 85 wt %˜95 wt % polyester fibers by high temperature so as to get spinning fabrics which are in melted form.

Ejecting: Extruding and ejecting the spinning fabrics to pass through a fabric ejection plate so as to form a melt ejection flow.

Forming an initial fiber: cooling the ejection flow leaving from the fabric ejection plate in low temperature and with a high speed to form an initial fiber;

Shaping: extending, coating oil, activating, drying, shaping, and packaging to form coconut based activated carbon polyester fibers with high percentage of carbons.

By above mentioned processes, the coconut based activated carbon polyester fibers have particle sizes smaller than 7 μm which are beneficial to make products, such as cloth, trousers, etc. In the present invention, the coconut based activated carbons are adhered to the polyester fibers firmly. Thus, even in washing, the coconut based activated carbon will not fall down. Furthermore since the particle sizes of the coconut based activated carbon are smaller than or equal to 7 μm, the percentage of the coconut based activated carbon can be increased to 5% ˜15% so as to have preferred filtering and adhesion effect. This can not be achieve by prior art polyester fiber.

The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
