Abstract

Disclosed herein are a button loop array and a method and apparatus for manufacturing the same, which are capable of improving the manufacturing efficiency of a button loop array that is cut into a plurality of button loops. The button loop array is configured such that a woven elastic yarn formed by weaving a single elastic yarn constructed by superimposing a plurality of spandex yarns is stacked on itself in a zigzag form so that one-side bent portions, lateral horizontal portions, and opposite-side bent portions are formed in multiple layers; the horizontal portions are vertically connected by a plurality of vertical connection yarns by winding the plurality of vertical connection yarns around circumferences of the horizontal portions with; and a plurality of loops protruding to one side in loop forms are each formed on one side of adjacent two horizontal portions between two or more horizontal portions.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A button loop array, wherein:
 a woven elastic yarn formed by weaving a single elastic yarn constructed by superimposing a plurality of spandex yarns is stacked on itself in a zigzag form so that one-side bent portions, lateral horizontal portions, and opposite-side bent portions are formed in multiple layers;   the horizontal portions are vertically connected by a plurality of vertical connection yarns by winding the plurality of vertical connection yarns around circumferences of the horizontal portions with; and   a plurality of loops protruding to one side in loop forms are each formed on one side of adjacent two horizontal portions between two or more horizontal portions.   
     
     
         2 . The button loop array of  claim 1 , wherein the horizontal portions are connected by forming a vertical sewing line in which a thread passes through the horizontal portions in a longitudinal direction of the button loop array. 
     
     
         3 . The button loop array of  claim 1 , wherein the spandex yarns are each configured such that at least one spandex rubber string is provided therein and one or more stretch yarns having elastic force are woven on an outer circumference of the spandex rubber string. 
     
     
         4 . The button loop array of  claim 1 , wherein:
 the plurality of spandex yarns include three spandex yarns; and   one of the three spandex yarns is formed thicker than remaining two spandex yarns so as to improve an elasticity of the woven elastic yarn while reducing a thickness of the woven elastic yarn.   
     
     
         5 . The button loop array of  claim 2 , wherein:
 the plurality of spandex yarns include three spandex yarns; and   one of the three spandex yarns is formed thicker than remaining two spandex yarns so as to improve an elasticity of the woven elastic yarn while reducing a thickness of the woven elastic yarn.   
     
     
         6 . The button loop array of  claim 3 , wherein:
 the plurality of spandex yarns include three spandex yarns; and   one of the three spandex yarns is formed thicker than remaining two spandex yarns so as to improve an elasticity of the woven elastic yarn while reducing a thickness of the woven elastic yarn.   
     
     
         7 . A method for manufacturing a button loop array, the method comprising:
 a woven elastic yarn producing step of superimposing a plurality of spandex yarns as a single elastic yarn through a guide and supply means, supplying the single elastic yarn to a circular weaving means, and producing a woven elastic yarn by using the single elastic yarn; and   a button loop array producing step of repeatedly forming one-side bent portions, horizontal portions and opposite-side bent portions in a downward direction by laterally moving the woven elastic yarn in a zigzag form while moving the woven elastic yarn downward, connecting the horizontal portions by a plurality of vertical connection yarns by winding the vertical connection yarns around circumferences of the horizontal portions whenever the horizontal portions are moved downward, and forming a plurality of loops each by protruding one side of adjacent two horizontal portions between two or more horizontal portions in a loop form, thereby producing a button loop array.   
     
     
         8 . The method of  claim 5 , further comprising, after the button loop array producing step;
 a sewing step of forming a vertical sewing line in which a thread passes through the horizontal portions in a longitudinal direction of the button loop array.   
     
     
         9 . The method of  claim 5 , wherein the spandex yarns are each configured such that at least one spandex rubber string is provided therein and one or more stretch yarns having elastic force are woven on an outer circumference of the spandex rubber string. 
     
     
         10 . The method of  claim 5 , wherein:
 the plurality of spandex yarns include three spandex yarns; and   one of the three spandex yarns is formed thicker than remaining two spandex yarns so as to improve an elasticity of the woven elastic yarn while reducing a thickness of the woven elastic yarn.   
     
     
         11 . The method of  claim 6 , wherein:
 the plurality of spandex yarns include three spandex yarns; and   one of the three spandex yarns is formed thicker than remaining two spandex yarns so as to improve an elasticity of the woven elastic yarn while reducing a thickness of the woven elastic yarn.   
     
     
         12 . The method of  claim 7 , wherein:
 the plurality of spandex yarns include three spandex yarns; and   one of the three spandex yarns is formed thicker than remaining two spandex yarns so as to improve an elasticity of the woven elastic yarn while reducing a thickness of the woven elastic yarn.   
     
     
         13 . An apparatus for manufacturing a button loop array, the apparatus comprising:
 an guide and supply means configured to superimpose three spandex yarns as a single elastic yarn and to move the single elastic yarn;   a circular weaving means configured to receive the single elastic yarn from the guide and supply means and to weave the single elastic yarn into a woven elastic yarn through lifting and lowering of a plurality of circular weaving needles; and   a button loop array producing means configured to repeatedly form one-side bent portions, horizontal portions, and opposite-side bent portions in a downward direction by laterally moving the woven elastic yarn in a zigzag form while moving it downward, to connect the horizontal portions by a plurality of vertical connection yarns by winding the vertical connection yarns around circumferences of the horizontal portions whenever the horizontal portions are moved downward, and to form a plurality of loops each by protruding one side of adjacent two horizontal portions between two or more horizontal portions in a loop form, thereby manufacturing a button loop array.
