Benefits of technology

The present invention aims to provide a non-woven fabric that is affordable and has good strength. The technical effect of this invention is to provide a cost-effective non-woven fabric that has desirable mechanical properties.

Problems solved by technology

Since the filament fiber is relatively expensive, cost of manufacturing the paper towel becomes high, which does not meet industry requirements.
The resultant wet paper towel is relatively rigid and is expensive due to high cost of rayon.

example 1

[0037]10 wt % polyethylene-polypropylene staple fibers (the average length was 6 mm) and 50 wt % pulp were mixed to form a composite fiber mixture, followed by air-laying treatment (the airflow volume was 130 CMM) and thermal treatment at a temperature of 135° C., thereby obtaining a composite fiber web.

[0038]20 wt % solid core polyethylene terephthalate filament fibers and shape 4T polyethylene terephthalate filament fibers (the average length thereof was 38 mm) were subjected to carding treatment so as to obtain filament fiber webs.

[0039]The composite fiber web was disposed between the two filament fiber webs followed by subjecting to water-jet treatment under 50 bar of waterjet pressure so as to obtain a non-woven fabric.

Abstract

A non-woven fabric includes a filament fiber web and a composite fiber web that is entangled with the filament fiber web and that includes composite staple fibers and cellulose fibers. The composite staple fibers and the cellulose fibers are fusion-bonded together. A method of fabricating a non-woven fabric includes: (a) air laying and thermally treating composite staple fibers and cellulose fibers so as to form a composite fiber web, the composite staple fibers and the cellulose fibers in the composite fiber web being fusion-bonded together, and (b) disposing the composite fiber web between two filament fiber webs followed by subjecting to water-jet treatment such that the composite fiber web and the filament fiber webs are entangled with each other.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority of Taiwanese application no. 101143448, filed on Nov. 21, 2012.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to a non-woven fabric, more particularly to a hygroscopic non-woven fabric which is composed of filament fibers, staple fibers and cellulose fibers.[0004]2. Description of the Related Art[0005]A paper towel is a necessity in daily life, and can be used to wipe and clean a surface of an article.[0006]The paper towel generally can be classified into dry paper towel and wet paper towel, and should exhibit the properties of softness and good tensile strength and absorbency.[0007]A conventional paper towel is made of two fiber webs by a water-jet treatment, in which the fiber webs are made of a plurality of filament fibers by a carding treatment. The filament fibers are chemical fibers and have a length ranging from 10 mm to 76 mm. Since the filament fiber is relat...
