BACKGROUND OF THE PRESENT INVENTION

Field of Invention

The present invention relates to waist belt, and more particularly to a metal-less waist belt which is an integral belt configured to be worn by the wearer during security test with metal detector and/or X-ray scanner and adapted to be under-worn by the wearer.

Description of Related Arts

Waist belts that do hold up clothing such as pants and skirts work by friction or buckles and often take advantages of the narrow circumference and the compressibility of the torso above the hips. Belts often are used as fashion accessories, with many colors, styles, and finishes. There are various kinds of waist belt such as bullet belt, studded belt, buckle belt, woven belt, fabric belt, statement belt, dress belt, tactical belt, and etc.

A conventional waist belt comprises an elongated belt strap and a buckle affixed to one end of the belt strap. The belt strap is generally made of leather, synthetic leather and the like, and the buckle, such as frame buckle, box frame buckle, ring buckle, plate buckle, snap buckle, or the like, is made of metal and assembled to one end of the belt strap by stitching, screwing, clamping, pressing stud, or other fastening means.

The industry of producing leather or synthetic leather is the third-largest contaminated industry after papermaking and brewery industry, wherein tanning sewage is not only measured greatly and the organic waste water is a kind of complicated component with high density that contains hazardous and noxious substances such as lime, dyestuff, protein, salt, grease, ammonia nitrogen, sulfide, chromic salts, hairs, skin slag, slit particles, and other suspended substance. For example, a tanned pigskin leather process needs one ton of water and includes at least four procedures having pollution problems, including the hair removal procedure that the removing hair or feathers from raw pig skin with lime that causes alkaline pollution, the grease removal procedure that the pigskin after depilation is placed in a rotary drum with grease-removing agent added and tons of sewage will be produced, the limbering procedure where chrome tanning acid and softening additive is added after degreasing the pigskin but such additive is a poison that just 0.01 g is enough to carcinogenic, and the dyeing procedure thereafter also cause great pollution.

Also, no matter the synthetic leather is produced by the wet method and the dry method, pollutants such as DMF (dimethylformamide), TOL (toluene), butanone, MEK (methylethylketone) organic exhaust gases, waste water and waste residue are produced during the coating, impregnation, and oven drying processes, that causes comparatively serious exhaust emission problems. For examples, DMR can invade human body through respiratory tract, skin and digestive tube causing toxic reaction. Toluene has big pungency to skin mucosa and can invade human body through respiratory tract and skin, influencing hematopoietic function and neural system. Butanone has to stimulate and anesthetic action, and long-term contact with butanone of skin can suppress sensation and produce dermatitis, hand and numbness of the fingers.

On the other hand, a normal individual has no problem to take off the waist belt for security test in the airport or at the entrance of a federal facility. However, for handicaps, disable people or seniors, especially to who is using walking cane, walker or wheelchair, it is inconvenience and not safe for him or her to take off and rewear the waist belt for passing the security test without assistance. For obese people, the waist belt is a tool for wearing his or her pants that once the waist belt is taken off, his or her pants will fall off and it is embarrassing to the obese person to keep using hands to hold the pants throughout the security test.

In addition, most of the waist belts in the market are designed for external use that is not suitable for under-wearing as an underwear belt which can be worn by the user for internal use such as wearing underwear for obese people, carrying internal pouch or pocket under external clothing, and etc.
