Elastic webbing, underpants and underwear

Abstract

The invention relates to the technical field of underwear, and comprises an elastic band body. The elastic band body is longitudinally foldable and a cross section thereof is a U-shaped structure. An adhesive layer is provided at an inner side of the elastic band body, and the elastic band body is wrapped on an edge of the underwear through its opening side and adhered by hot pressing to fix on the underwear. While ensuring that a width of the elastic band remains unchanged, the elastic band body is longitudinally folded and wrapped on the edge of the underwear to form a double-layer structure, thus to double its elastic force. Besides, the elastic band body is adhered and fixed to the underwear by bonding without seaming, which reduces the dependence on the seaming work, realizes complete bonding, and increases the wearing experience of the product and orderliness of the product.

What is claimed is: 
     
         1 . An elastic webbing, comprising an elastic band body, wherein the elastic band body is longitudinally foldable and a cross section thereof is a U-shaped structure;
 an adhesive layer is provided at an inner side of the elastic band body in a folded state,   and the elastic band body is wrapped on both inner and outer sides of an edge of an underwear through its opening side and then is adhered to the underwear by means of hot pressing so as to fix on the underwear.   
     
     
         2 . The elastic webbing according to  claim 1 , wherein the elastic band body is bent until a head is connected to a tail, and a connecting structure is provided at a head-tail junction of the elastic band body, so that the elastic band body is in a circular shape with the head being connected to the tail. 
     
     
         3 . The elastic webbing according to  claim 2 , wherein the connecting structure includes a boneless seaming connection structure. 
     
     
         4 . The elastic webbing according to  claim 2 , wherein the connecting structure includes a connecting cloth arranged on an outer side of the elastic band body, and the connecting cloth is adhered to the head-tail junction of the elastic band body by means of hot pressing. 
     
     
         5 . The elastic webbing according to  claim 1 , wherein the elastic band body is integrally formed. 
     
     
         6 . The elastic webbing according to  claim 1 , wherein a labeling portion is provided at an outer side of the elastic band body. 
     
     
         7 . An underpants, comprising a pants body, and the elastic webbing as claimed in  claim 1 , wherein the elastic band body is bent until a head is connected to a tail, and a head-tail junction of the elastic band body is connected through boneless seaming connection; an edge of the pants body is embedded through an opening side of the elastic band body and touches a bending portion of the elastic band body, and the elastic band body is adhered to the pants body by means of hot pressing. 
     
     
         8 . A underwear, comprising an underwear main body, and the elastic webbing as claimed in  claim 1 , wherein a connecting structure is provided at ends of the elastic band body, an edge of the underwear main body is embedded through an opening side of the elastic band body and reaches a bending portion of the elastic band body, and the elastic band body is adhered to the underwear main body by means of hot pressing.
