Benefits of technology

[0009] The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide an anti-allergen fabric, which has a great anti-allergen effect and is durable in use.
[0010] It is another object of the present invention to provide an anti-allergen fabric, which is inexpensive to manufacture.

Problems solved by technology

Because fine yarns for weaving anti-allergen fabrics are commonly formed of natural or synthetic fibers, the fine yarns have a limited strength.
However, a woven fabric made of synthetic fibers does not provide a nice touch.
If natural fibers of the first class are used to make the woven fabric, the cost of the woven fabric will be very expensive so that the woven fabric will be less acceptable to the consumers.
Further, a woven fabric of fine yarns normally has a relatively thinner thickness so that it is breakable when undergoing wash and / or a long time of use, thereby lowering the anti-allergen effect and limiting the duration thereof.

first embodiment

[0020] Referring to FIG. 1, an anti-allergen fabric 10 in accordance with the present invention is a woven fabric of warp yarns 12 and weft twines 14. Each warp yarn 12 is formed of twisted cotton fibers. Each weft twine 14 is formed of two yarns 15 arranged in parallel. The mean pore size of the anti-allergen fabric 10 is about 9 μm so that the anti-allergen fabric 10 can effectively block allergens such as pollens, dust mites, etc. Because each weft twine 14 is formed of two yarns 15, the strength of the weft twine 14 is substantially increased. During weaving, the weft twines 14 can bear a high stretching force so that more weft twines 14 can be woven in each unit area. Therefore, natural fibers of usual class can be used to make the weft twines 14 and the warp yarns 12, and sufficient weft twines 14 and warp yarns 12 can be woven into each unit area to form the desired anti-allergen fabric 10 having a mean pore size equal to or less than about 9 μm, which can effectively block a...

third embodiment

[0023] It is to be easily understood that there are a variety of alternative embodiments that can achieve the same effects as the aforesaid embodiments without departing from the spirit and scope of the invention. For example, FIG. 3 shows an anti-allergen fabric 30 in accordance with the present invention. The anti-allergen fabric 30 is a woven fabric of warp twines 32 and weft twines 34. According to this embodiment, each warp twine 32 is formed of two yarns 33 that are arranged in parallel, and each weft twine 34 is formed of two yarns 35 that are twisted together. This embodiment allows more yarns to be woven in each unit area so that the woven fabric can have a relatively smaller mean pore size. Further, this embodiment allows the use of relatively cheaper fibers to save the cost.

fourth embodiment

[0024]FIG. 4 shows an anti-allergen fabric 40 in accordance with the present invention. The anti-allergen fabric 40 is a woven fabric of warp twines 42 and weft yarns 44. According to this embodiment, each warp twine 42 is formed of two yarns 43 arranged in parallel.

[0025]FIG. 5 shows an anti-allergen fabric 50 in accordance with a fifth embodiment of the present invention. The anti-allergen fabric 50 is a woven fabric of warp twines 52 and weft yarns 54. The fifth embodiment is similar to the aforesaid fourth embodiment with the exception that according to this embodiment, each warp twine 52 is formed of two yarns 53 that are twisted together.

Abstract

An anti-allergen fabric is woven by warp yarns and weft twines, wrap twines and weft yarns, or wrap twines and weft twines. Each of the wrap twines or weft twines is formed of a plurality of yarns. The anti-allergen fabric has a mean pore size not greater than 9 μm. Therefore, the anti-allergen fabric has advantages of relatively better anti-allergen effect, longer duration in use and lower manufacturing cost.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] The present application is a divisional application of U.S. patent application Ser. No. 11 / 387,946 filed on Mar. 24, 2006.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to fabrics and more particularly, to an anti-allergen woven fabric that is inexpensive to manufacture and durable in use. [0004] 2. Description of the Related Art [0005] Conventional anti-allergen fabrics are woven fabrics of fine yarns. The greater the number of yarns in a unit area of the fabric, the smaller the mean pore size of the fabric will be. When the mean pore size of a fabric is smaller than the size of the allergen, such as pollen, dust mite, etc., the fabric can provide an anti-allergen effect. Normally, the conventional anti-allergen fabric has a mean pore size smaller than about 10 μm. [0006] Because fine yarns for weaving anti-allergen fabrics are commonly formed of natural or synthetic fibers, the fine ya...
