Definitions

  • 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.
  • a paper towel is a necessity in daily life, and can be used to wipe and clean a surface of an article.
  • 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.
  • 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 relatively expensive, cost of manufacturing the paper towel becomes high, which does not meet industry requirements.
  • Taiwanese patent publication No. 182129 discloses a wet paper towel which includes two wiping layers and an absorbent layer disposed between the wiping layers.
  • the wiping layers and the absorbent layer are entangled using hot rolling treatment.
  • the wiping layers are made of fibers obtained from the kapok tree and having a length ranging from 1.25 mm to 5 mm.
  • the absorbent layer is made by mixing 50wt% rayon and 50wt% polypropylene fibers followed by subjecting to hot wind treatment.
  • the resultant wet paper towel is relatively rigid and is expensive due to high cost of rayon.
  • a first object of the present invention is to provide a non-woven fabric, which is cost effective and exhibits desirable mechanical properties.
  • a second object of the present invention is to provide a method of fabricating the non-woven fabric.
  • a non-woven fabric which includes a filament fiber web and a composite fiber web.
  • the composite fiber web is entangled with the filament fiber web and 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 which includes:
  • a non-woven fabric according to the present invention includes a filament fiber web that is made from filament fibers, 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.
  • the non-woven fabric has a basis weight ranging from 20 g/m 2 to 120 g/m 2 and a thickness ranging from 0.1 mm to 5 mm.
  • the non-woven fabric of the present invention can be applied to manufacture of a paper towel, a facial mask or a panty liner.
  • Each component of the non-woven fabric of the present invention is illustrated as follows.
  • the filament fiber suitable for the present invention is a natural fiber, a chemical fiber, or the combination thereof.
  • the natural fiber can be a plant fiber, an animal fiber, or the combination thereof.
  • the plant fiber include, but are not limited to, seed fibers (such as cotton), bast fibers (such as flax or hemp), nervure fibers (such as Manila hemp), or fruit fibers (such as coconuts).
  • the animal fiber include, but are not limited to, hide fibers and silk fibers.
  • the chemical fiber suitable for the present invention is a regenerated fiber, a semi-synthetic fiber, a synthetic fiber, or combinations thereof.
  • An example of the regenerated fiber is rayon.
  • the semi-synthetic fiber is, e.g., cellulose acetate fiber.
  • Examples of the synthetic fiber include polyethylene (abbreviated as PE) fiber, polypropylene (abbreviated as PP) fiber, polyethylene terephthalate (abbreviated as PET) fiber, and polyamide fiber.
  • the filament fiber is selected from the group consisting of PE fibers, PP fibers, PET fibers, rayon, cotton fibers, and combinations thereof.
  • the filament fiber is present in an amount ranging from 10wt% to 80wt% based on 100wt% of the hygroscopic non-woven fabric.
  • the filament fiber has a linear density ranging from 1 denier to 6 deniers per filament.
  • the filament fibers have lengths ranging from 10 mm to 76 mm.
  • the composite staple fiber has thermofusible ability, and thus can be fusion-bonded with the adjacent cellulose fibers.
  • the cellulose fibers would not be lost during a subsequent water-jet treatment, thereby eliminating the inferior absorbency problem of the hygroscopic non-woven fabric and difficulty in wastewater treatment.
  • the composite staple fiber suitable for the present invention is selected from the group consisting of a polyethylene-polypropylene fiber, a polyethylene-polyethylene terephthalate fiber, a low temperature poly lactic acid-high temperature poly lactic acid fiber, a maleic anhydride modified polyethylene-polypropylene fiber, a maleic anhydride modified polyethylene-polyethylene terephthalate fiber, and combinations thereof.
  • the composite staple fiber is the polyethylene-polypropylene fiber.
  • the composite staple fiber is present in an amount ranging from 1wt% to 20wt% based on 100wt% of the non-woven fabric.
  • the composite staple fiber has a linear density ranging from 1 denier to 6 deniers per filament.
  • the composite staple fibers have lengths ranging from 1 mm to 10 mm.
  • the cellulose fiber is a natural cellulose fiber, and is present in an amount ranging from 5wt% to 60wt% based on 100wt% of the non-woven fabric.
  • the cellulose fiber has a linear density ranging from 0.1 denier to 10 deniers per filament.
  • the cellulose fiber has a length ranging from 1 mm to 5 mm.
  • the cellulose fiber can be obtained from pulp, e.g., wood pulp.
  • a method of fabricating the non-woven fabric of this invention includes the following steps:
  • the air-laying treatment in step (a) is conducted using air as a carrier for the fibers.
  • the composite staple fibers and the cellulose fibers are dispersed evenly in the gas (e.g., air) by air flowing, and are adsorbed onto a screen mesh, so as to form the composite fiber web.
  • the air-laying treatment can be conducted using a traditional air-laying machine.
  • the airflow volume used in the air-laying treatment ranges from 100 CMM to 1000 CMM.
  • the thermal treatment is conducted to fusion-bond the composite staple fibers and the cellulose fibers together.
  • the thermal treatment can be conducted using traditional heating equipment.
  • the heat treatment is conducted at a temperature ranging from 50°C to 180°C.
  • the composite fiber web has a basis weight ranging from 5 g/m 2 to 100 g/m 2 and a thickness ranging from 0.1 mm to 10 mm.
  • Each of the filament fiber webs used in step (b) is formed by carding the filament fibers.
  • the carding treatment can be conducted using traditional carding equipment.
  • the filament fiber web has a basis weight ranging from 5 g/m 2 to 100 g/m 2 and a thickness ranging from 0.1 mm to 10 mm.
  • the water-jet treatment is conducted using a high pressure waterjet to render the fusion-bonded fibers in the composite fiber web to be entangled with the filament fibers in the filament fiber webs.
  • the water-jet treatment can be conducted using traditional water-jet equipment.
  • 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.
  • Examples 2 to 6 and Comparative Example were conducted in a manner similar to that of Example 1 except for the material and amount of the filament fiber, the composite staple fiber, and/or the cellulose fiber.
  • the material and the amount of each of the fiber components are listed in Table 1.
  • the basis weight was measured by ASTM D3776-85 under the following conditions: the temperature of 23 ⁇ 0.5°C, the relative humidity of 65 ⁇ 2% and the normal atmospheric pressure. The results are shown in Table 1.
  • the non-woven fabrics of Examples 1 to 6 and Comparative Example were cut into samples with the length of 250 mm and the width of 25 mm, and were placed under the conditions of the temperature of 23°C and the relative humidity of 50% for 24 hours, followed by subjecting to softness test according to ISO 9073-7:1995 and ASTM D-1117.
  • the softness test was conducted based on the following procedure using a flexural rigidity tester which included a horizontal platform and an inclined surface that was inclined at 45° relative to the horizontal platform.
  • the non-woven fabric of the present invention that uses composite staple fibers and cellulose fiber to replace some of the filament fibers has superior elongation rate and absorbency as compared to the non-woven fabric of the comparative example.
  • Other properties e.g., tensile strength, water content, and softness also meet industrial requirements.
  • the non-woven fabric of the present invention that uses composite staple fibers and cellulose fibers has reduced cost and superior elongation rate and improved absorbency. Furthermore, the air-laying treatment, thermal treatment, carding treatment and water-jet treatment can be combined in a production line to efficiently fabricate the non-woven fabric of the present invention.
