Wetsuit made with a low-absorbent, good wicking and quick drying fabric
An improved low-absorbent, good wicking and quick drying wetsuit fabric is made of non-absorbent fiber, processed with water repellent before being knitted, and high-absorbent fiber, processed with absorbent agent while being dyed and/or heat set, then knitted by a circular knitting machine under a setting of 18˜42 gauge per inches to form a structure of two-layer fabric. The outer side (the non-absorbent fiber) touches the skin of the wetsuit wearer to wick out the water, leaked into the space between the wearer and the wetsuit, quicker and make the wearer feel dry and comfortable. The inner side (the high-absorbent fiber) is laminated with rubber sponge to absorb the water, leaked from the body of the wetsuit, and wick the water out through the outer side (the non-absorbent fiber). Appropriate cutting and sewing steps are employed to finish the formation of the wetsuit. In an alternative embodiment, the outer side may comprise a fiber made of a combination of non-absorbent yarn and absorbent yarn.

BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to the field of wetsuits used for diving, surfing and the like, and more specifically to an improved low-absorbent, good wicking and quick drying wetsuit fabric that is made of non-absorbent fiber, processed with water repellent before being knitted, and high-absorbent fiber, processed with absorbent agent while being dyed and/or heat set, then knitted by a circular knitting machine under a setting of 18˜42 gauge per inches to form a structure of two-layer fabric. The outer side (the non-absorbent fiber) touches the skin of the wetsuit wearer to wick out the water, leaked into the space between the wearer and the wetsuit, quicker and make the wearer feel dry and comfortable. The inner side (the high-absorbent fiber) is laminated with rubber sponge to absorb the water, leaked from the body of the wetsuit, and wick the water out through the outer side (the non-absorbent fiber).
The non-absorbent fiber is selected from the group of polyester, polyamide or polypropylene having a fineness ranging from 30 denier to 200 denier, and processed with water repellent before knitting, and the high-absorbent fiber is selected from the group of polyester or polyamide having a fineness ranging from 30 denier to 200 denier, and processed with an absorbent agent while dying and/or heat setting.
The present invention comprising the newly improved low-absorbent, good wicking and quick drying fabric that forms the wetsuit, not only provides the wearer a dry and comfortable inner feel, but also is easy to take off or put back on after use.
2. Background Art
After wearing a conventional wetsuit for a certain time while diving or related activities, where the wearer is immersed in the water, the water will leak into the space between the wetsuit and the wearer from neck, end of sleeves or legs, or wetsuit directly. Such leaked water will cause the wearer to feel cold, heavy, and uncomfortable, especially when the wearer leaves the water. Furthermore, it is difficult to take the wetsuit off when the wetsuit has absorbed water, especially when the wearer puts on the wet, cold, and water absorbed wetsuit again.
It would be highly advantageous if it were possible to make the water between the space of wearer and wetsuit, wick out quicker and dry sooner. That will make the wearer feel dry, more comfortable, and make it easier to take the wetsuit off, subsequently re-wear it, or even obviate the need to take it off because the wetsuit will be much drier or more comfortable out of the water as compared to wetsuits made of more conventional fabrics.
SUMMARY OF THE INVENTIONThe present invention comprises a wetsuit used for diving, surfing and the like, and more specifically to a wetsuit made of an improved low-absorbent, good wicking and quick drying fabric.
The improved low-absorbent, good wicking and quick drying fabric is made of non-absorbent fiber and high-absorbent fiber that form a structure of two-layer fabric. The outer side (the non-absorbent fiber) touches the skin of wetsuit wearer to wick the water, leaked into the space between the wearer and the wetsuit, out quicker and make the wearer feel dry and comfortable. The inner side (the high-absorbent fiber) is laminated with rubber sponge to absorb the water, leaked from the body of the wetsuit, and wick the water out through the outer side (the non-absorbent fiber).
Both the non-absorbent fiber and the high-absorbent fiber are selected from the group of polyester and polyamide.
The non-absorbent fiber is processed with water repellent before being knitted and the high-absorbent fiber is processed with the absorbent agent later while being dyed. This series of steps provides the performance and capabilities of low absorbent, good wicking and quick drying and makes the wetsuit wearer feel light, dry, and comfortable after leaving the water.
Both the non-absorbent fiber and the high-absorbent fiber have a fineness ranging from 30 denier to 200 denier,
The non-absorbent fiber and the high-absorbent fiber are knitted by a circular knitting machine under a setting of 18˜42 gauge per inches.
The finished low-absorbent, good wicking and quick drying fabric is at a weight of 20.7 g/M2 (and is preferably in the range of 100 g/M2 to 340 g/M2) gram/yard, a width of 56 inches (preferably in the range of 50 to 72 inches), and the elongation capability in the vertical is 160% and horizontal directions is 130%. Elongation in either direction is preferably in the range of 100% to 300%.
The improved low-absorbent, good wicking and quick drying wetsuit fabric is laminated with a rubber sponge material. Appropriate cutting and sewing steps are employed to finish the formation of wetsuit.
Compared with conventional wetsuit fabric, the newly improved low-absorbent, good wicking and quick drying wetsuit fabric of the present invention offers excellent performance. In testing the inventive fabric to compare its drying time to conventional wetsuit fabric, it took approximately three minutes to dry to the same degree that it took a conventional fabric at least 30 minutes. It is believed to be the first time that wetsuit fabric is made of rubber sponge laminated with low-absorbent, good wicking and quick drying fabric, comprising non-absorbent fiber, processed with the water repellent before knitted, and high-absorbent fiber, processed with the absorbent agent while being dyed and/or being heat set.
