The present invention relates to a woven textile.
A conventional woven textile is woven by threads in longitudinal direction and horizontal direction. The woven textile has to be woven close to prevent from deformation. However, the woven textile is disadvantageous in bad permeability because the gap between threads is small.
In addition, the close woven textile has a bad resilience and extension. When the textile is used in objects which needs better extension, such as shoe body, the object becomes too tight and without comfort.
Besides, conventional filament is made of material having a bad tolerance of extension and wearing. On the contrary, the filament has a high tolerance of deformation in radial direction so that the filament is compressed when knotting to make the knot smaller. Thus, the woven textile has a flat appearance and lacks of three-dimensional appearance.
Another type of woven textile doesn't knot but fixes the threads by melting the plastic material coated on the threads at the overlap portions of the threads. However, the fixation is weak and easy to strip. Besides, the filament has a low tolerance of extension.
The main object of the present invention is to provide a woven textile having high tolerance of extension. In addition, the woven textile has sufficient structure strength and fixation without step of melting.
To achieve the above and other objects, the woven textile of the present invention is woven by a plurality of first threads and a plurality of second threads. Each of the first threads is a TPU (Thermoplastic polyurethanes) filament which is integrally formed. The first threads are parallel arranged at intervals. The second threads are arranged at intervals to weave with the first threads for fixation so that the woven textile is formed with a plurality of through holes. Each of the second threads is knotted with the first threads to form a plurality of first knots. Each of the second threads is knotted itself between any two adjacent ones of the first threads to form at least one second knot. The first threads are separated apart by the at least one second knot to prevent the first threads from touching each other.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.
Please refer to
In the present embodiment, each of the second threads 20 is made of artificial sinew, TPU filament, or other conventional filament for weaving. Preferably, the first threads 10 are formed by a single filament extending back and forth to be plural rows of first thread 10.
Besides, each of the second threads 20 has an outer diameter smaller than one fifth an outer diameter of each of the first threads 10. Each of the first threads 10 is compressed by the second threads 20 at the first knots 21 to have an outer diameter which is 0.9-1.0 time an original outer diameter of each of the first threads 10, as shown in
The first threads and the second threads are fixed to each other by knotting instead of meting. Thus, the threads are fixed firmly, and the woven textile has a three-dimensional appearance. In addition, the first thread is made of TPU to be difficult to be compressed radially when knotting to provide a more three-dimensional appearance. The TPU first thread further has a higher friction to prevent from slipping. Besides, the TPU first thread has a better tolerance of extension, so the woven textile can be used in wide fields and is more durable. In addition, the TPU filament is better in wear resistance.
