Description
BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a woven fabric, and more particularly to a woven fabric for promoting heat dissipation.

2. Description of Related Art

To avoid stinky smell of sweat occurring on the conventional woven fabric, the conventional woven fabric is mainly produced with gas permeable fibers. When the conventional woven fabric is worn by a wearer, air flow may permeate to the skin and lower the body temperature of the wearer, and the wearer may feel less muggy with less sweat cohering between the body of the wearer and the conventional woven fabric (compared with traditional woven fabrics which are not gas permeable).

However, the conventional woven fabric may still contact the wearer's skin at a large area. Under such situation, air cannot fluently flow over the skin, and as a result, the wearer may still feel muggy and uncomfortable.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a woven fabric for promoting heat dissipation. The woven fabric has multiple channels formed thereon, so air may fluently flow over the wearer's skin, lower the wearer's body temperature, and reduce sweating.

The present invention provides a woven fabric for promoting heat dissipation. The woven fabric covers a wearer's skin when in use, and comprises two surface layers and an intermediate layer. The two surface layers are disposed at a spaced interval, and comprise a first surface layer and a second surface layer oriented to the wearer's skin when the woven fabric is in use. The second surface layer has multiple braids disposed parallelly, and each one of the multiple braids is straight. The intermediate layer is formed with multiple monofilaments which are woven between the multiple braids of the second surface layer and the first surface layer. An insole and a clothing which adopt the woven fabric are provided as well.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1 to 4, a first embodiment of a woven fabric for promoting heat dissipation in accordance with the present invention covers a wearer's skin when in use, and the woven fabric comprises two surface layers 10, 20 and an intermediate layer 30.

The two surface layers 10, 20 are disposed at a spaced interval, and comprise a first surface layer 10 and a second surface layer 20. The intermediate layer 30 is woven between the two surface layers 10, 20. In the first embodiment of the present invention, the first surface layer 10 has a flat surface. The second surface layer 20 is oriented to the wearer's skin when the woven fabric is in use, and has multiple parallelly disposed braids 21. Each one of the multiple braids 21 is straight.

With reference to FIGS. 3 and 3A, the woven fabric may be applied on an insole 50, wherein the first surface layer 10 abuts an insole body 51 of the insole 50 as the woven fabric is fixed to the insole body 51. Then the second surface layer 20 faces upwardly. When the wearer wears the insole 50, the wearer's foot may directly step on the multiple braids 21 of the second surface layer 20, or may indirectly step on the multiple braids 21 via a sock.

On the other hand, with reference to FIG. 4, the woven fabric may also be used to produce a clothing 60, when the first surface layer 10 is located at an exterior side of the clothing 60, and the second surface layer 20 is located at an interior side of the clothing 60. When the wearer wears the clothing 60, the wearer's body directly contacts the multiple braids 21 of the second surface layer 20, or indirectly contacts the multiple braids 21 via underwear.

Besides, the woven fabric may be used to produce a shoe tongue, a shoe topline, a backpack, a bedspread, linings of leather gloves, etc. In all of these applications, the woven fabric directly or indirectly contacts the wearer's skin with the second surface layer 20, i.e. the second surface layer 20 is oriented toward the wearer's skin. With reference to FIG. 2, the intermediate layer 30 is formed with multiple monofilaments 301 which are woven between the multiple braids 21 of the second surface layer 20 and the first surface layer 10. Furthermore, the woven fabric has multiple channels 31. Each one of the multiple channels 31 is formed among the intermediate layer 30 and adjacent two of the multiple said braids 21. In the first embodiment of the present invention, with reference to FIG. 2, the multiple monofilaments 301 of the intermediate layer 30 divergently stretch out from each one of the multiple braids 21, toward the first surface layer 10, and thereby each one of the multiple channels 31 has a V-shaped cross section.

With reference to FIG. 5, the first surface layer 10 has multiple first fibers 11 and multiple second fibers 12. The multiple first fibers 11 are parallelly disposed. Each one of the multiple second fibers 12 is shuttled back and forth through adjacent three of the multiple first fibers 11, so as to weave the second fiber 12 and the three first fibers 11 together. The multiple second fibers 12 are parallel to each other, so every said first fiber 11 may be woven serially. The first surface layer 10 is therefore made flat by the aforementioned weaving process.

Moreover, with reference to FIG. 6, each one of the multiple braids 21 is made of a first yarn 211 and a second yarn 212. The first yarn 211 and the second yarn 212 are interlaced with each other to improve structural strength of the braid 21. The positions 211A, 211B, 211C, 212A, 212B, 212C depicted in FIG. 6 specify routes of the two yarns 211, 212. The first yarn 211 passes through the positions 211 A, 211B, 211C, and the second yarn 212 passes through the positions 212A, 212B, 212C correspondingly.

With reference to FIG. 7, a second embodiment of the present invention differs from the first embodiment in that: each one of the multiple braids 21 has a first yarn 211, a second yarn 212, and a shuttling yarn 213. The first yarn 211 and the second yarn 212 are each independently woven, and extend straight respectively. The shuttling yarn 213 is shuttled back and forth, and weaves the first yarn 211 and the second yarn 212 to form the braid 21. Besides, number of yarns of each braid 21 may be adjusted. For example, the braid 21 may be formed by one said shuttling yarn 213 weaving three straight yarns.

With reference to FIG. 8, when the wearer wears the woven fabric of the present invention for promoting heat dissipation, due to the orientation of the second surface layer 20 toward the wearer's skin, heat discharged by the wearer may be rapidly brought out by air flowing through the multiple linear channels 31 among the multiple braids 21. Furthermore, since the intermediate layer 30 is formed with the monofilaments 301, larger apertures may be formed between the monofilaments 301, and air flow may thereby more rapidly leave via the apertures. As a result, the wearer's body temperature may be lowered fast. The wearer may feel much less muggy and more comfortable. Sweat may also be reduced, so the woven fabric is prevented from stinky smell.

In addition, the divergently stretching monofilaments 301 can improve the ability of the second surface layer 20 to withstand pressure, prevent the multiple braids 21 from being squeezed and skewed, and prevent the channels 31 from being compressed. Therefore, the divergently stretching monofilaments 301 can prevent the channels 31 from reduction of ventilation effect.

When the woven fabric is used to produce the insole 50, with reference to FIG. 3, each one of the multiple braids 21 extends in a widthwise direction of the insole 50, so the multiple braids 21 may provide a higher friction for anti-slip effect.

With the aforementioned technical characteristics, the woven fabric of the present invention has the following advantages.

1. Good ventilation effect: Due to the orientation of the second surface layer 20 toward the wearer's skin, heat discharged by the wearer may be rapidly brought out by air flowing through the multiple linear channels 31 among the multiple braids 21.

2. Reduction of sweat of the wearer: Since the intermediate layer 30 is formed with the monofilaments 301, larger apertures may be formed between the monofilaments 301, and air flow may thereby more rapidly leave via the apertures. As a result, the wearer's body temperature may be lowered fast, and sweat may also be reduced.

3. Prevention of stinky smell: Following reduction of sweat, stinky smell may be prevented from occurring to the woven fabrics.

Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
