Abstract
Description
Technical Field
[0001] The utility model relates to a knitted belt, in particular to an elastic knitted belt which can be used for the fleece surface of a hook and loop fastener. Background Art
[0002] At present, Velcro is widely used in the textile industry and other daily life, among which ready-made clothes, automotive products, shoes, and bags are the most widely used, such as cuffs, pockets, shoelaces, bag openings, computer cable ties, etc. The fleece side of the Velcro used is mostly non-elastic. The fleece is fixed by sizing and then divided into strips. The process is relatively long and the feel is relatively hard. The strip edges are sharp when divided into strips, which can easily scratch the skin. Traditional underwear mostly uses metal hooks. The hooks need to be sewn to the underwear fabric first and then connected to the underwear. There is a certain distance between the buckles. When adjusting, it is limited by the distance between the two holes, and it cannot be adjusted steplessly. When wearing, you need to turn your hand back to the back to put the hook into the buckle, which is difficult for first-time wearers. For adjusting shoulder straps or girdles, 8-shaped buckles or 6-shaped buckles are mostly used with webbing with adjustment holes. The shoulder straps with 8-shaped buckles need to be adjusted in length before wearing. When wearing, they will slip with the movement of the human body, causing the shoulder straps to become longer and need to be adjusted again. The 6-shaped buckle with the webbing with adjustment holes is mostly a woven structure, with a certain distance between the holes. When adjusting, it is limited by the distance between the two holes and cannot be adjusted steplessly. When Velcro is used with elastic fabric, the method adopted is mostly to sew the Velcro piece with the elastic webbing or fabric first, and then sew or heat press it with the use part of the clothes. It requires multiple sewing, and the adjustable length is also limited by the size of the Velcro piece. Utility Model Content
