Elastic fabric with ventilation effect

Abstract

An elastic fabric may be knitted and made by a plurality of rubber threads, first elastic wefts, second elastic wefts, first wraps, second wraps and winding wraps. The rubber thread, the first elastic weft, and the second elastic weft are elastic, and the first elastic weft and the second elastic weft are knitted across and interlaced with the rubber thread at right angles such that the elastic fabric is configured to be stretched in all directions. The first elastic weft and the second elastic weft are wrapped on at least three rubber threads to form a plurality of breathing holes therebetween, and the first wrap and the second wrap are wrapped along the rubber thread such that the elastic fabric is configured to have the solid structure and the great ventilation effect simultaneously.

What is claimed is: 
     
         1 . An elastic fabric knitted and made by a plurality of rubber threads, first elastic wefts, second elastic wefts, first wraps, second wraps, and winding wraps;
 wherein the rubber threads are arranged parallel with each other, and at least three rubber threads as a first group are wrapped by the first elastic weft and the second elastic weft; wherein a weaving process is to repeat an S-shaped and inverted S-shaped pattern along a direction of the rubber thread, and the first elastic weft and the second elastic weft are configured to wrap across a middle rubber thread first and toward and across a first adjacent rubber thread at one side of the middle rubber thread, and go back to sequentially wrap across the first adjacent rubber thread, the middle rubber thread and a second adjacent rubber thread at another side of the middle rubber thread, and then go back to wrap across the second adjacent rubber thread and the middle rubber thread to complete the S-shaped weaving pattern; the inverted S-shaped weaving pattern comes after the S-shaped weaving pattern that the first elastic weft and the second elastic weft are configured to start from an opposed direction to wrap across the middle rubber thread toward and across the second adjacent rubber thread first, and sequentially wrap across the three rubber threads, and then go back to wrap across the first adjacent rubber thread and the middle rubber thread to complete the inverted S-shaped pattern such that each of the breathing holes is formed at a gap between the S-shaped and the inverted S-shaped weaving pattern, and a plurality of junctions are formed at contacting points between the first elastic weft and the rubber thread and between the second elastic weft and the rubber thread; wherein when the elastic fabric has more than three rubber threads, the second adjacent rubber thread of the first group is served as a first adjacent rubber thread of a second group to keep and extend the weaving pattern; the first wrap and the second wrap configured to respectively wrap across an upper surface and a lower surface of the rubber thread are knitted and crossed between two lateral sides of the rubber thread in a bit stream pattern along the rubber thread with the same interval to respectively form a top surface and a bottom surface of the elastic fabric; each of the winding wraps arranged along the rubber thread comprises a plurality of knot points which are respectively knitted at the junctions and configured to tightly secure positions of the rubber thread, the first elastic weft, the second elastic weft, the first wrap and the second wrap to form the elastic fabric.   
     
     
         2 . The elastic fabric of  claim 1 , wherein the first wrap and the second wrap are made of fabric material such as nylon, charcoal yarn, or cotton yarn. 
     
     
         3 . The elastic fabric of  claim 1 , wherein the first wrap and the second wrap are knitted and crossed between the two lateral sides of the rubber thread in the bit stream pattern along the rubber thread with the same interval, and each of the intervals longitudinally spans two junctions, and each of crossing points on the rubber thread is positioned on the junction.
