Benefits of technology
[0006]The present invention provides a life vest that can overcome the aforesaid drawbacks and improve the related function.
[0009]Compared with the nylon life vest, the present invention can offer high elasticity that makes the life vest better fitting and makes the wearer feel more comfortable. Based on the advantage of high elasticity, the present invention can be provided in different patterns or figures of design that creates improved aesthetics.
[0011]The prior art sandwich life vest, has structural strength that is almost exclusively supported by monofilament that causes weaker structural strength or is inclined to wrinkle after being folded or compressed. The present invention is made of elastic yarn and non elastic yarn, and the structural strength is supported by the robust and rigorous knitting method that can offer improved structural strength, and improved abilities of bending and better physical memory and provides a life vest that can last longer and feels softer.
Problems solved by technology
The nylon life vest has the drawback of no elasticity, fails to fit the wearer and makes the wearer feel uncomfortable.
The neoprene life vest offers the elasticity to solve the drawbacks of the nylon life vest, but has the disadvantage of non-breathing, heavy, and not environment friendly.
It solves the drawbacks of the neoprene life vest but also has the disadvantage of weaker strength and less physical memory, and is easily frayed while cutting.

Embodiment Construction
[0017]With reference to FIGS. 1A and 1B, the surface of a nylon life vest has no elasticity and that makes the wearer feel uncomfortable and the finished product of nylon life vest also has little aesthetic appeal.
[0018]With reference to FIGS. 2A and 2B, a neoprene life vest offers a soft surface and makes the finished product better fitting, but the main substance of neoprene is rubber which causes the neoprene life vest to be non-breathing, and require gluing and laminating in the manufacturing process. The use of neoprene material also raises the drawback of an environmental issue.
[0019]With reference to FIGS. 3A and 3B, the structural strength of the surface of the sandwich life vest is supported solely by a monofilament that is too weak to offer sufficient strength to form the required bending and physical memory characteristics. The outer and inner materials of the sandwich life vest of FIG. 3 are easily deformed while aging or while being folded or compressed.

A life vest manufactured from an improved fabric, having a thickness ranging from 1.4 mm to 3.0 mm, and high elasticity provided by knitting with a double circular knitting machine under the setting of 20-28 gauges per inch. The improved thickness and high elasticity fabric is made of non-elastic yarns, selected from polyester, polyamide, or polypropylene, and from elastic yarns, of polyurethane. The combination of woven elastic and non-elastic yarns provides an intricate yet highly comfortable fabric which is soft and “furry” to the touch.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priorty from U.S. Provisional Patent Application Ser. No. 61 / 175,434 filed May 4, 2009.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to the field of life vests, and especially to a life vest that is manufactured from an improved high elasticity fabric under an arrangement of knitting using a double circular knitting machine under the setting of 20-28 gauges per inch. The fabric includes 80 wt % to 97 wt % of non-elastic yarns, made from polyester, polyamide, or polypropylene having a fineness range from 50 denier to 150 denier, and 3wt % to 20 wt % of elastic yarns, made from polyurethane having a fineness range 10 denier to 70 denier, based on the total weight of the said fabrics. The improved fabric has an elongation ranging from 30% to 90% in a first direction and an elongation ranging from 60% to 120% in a second direction transverse to the first direction. The im...
