How to connect coated webbing?

 Webbing is widely used in many products such as bags and clothes. Of course, we can usually see several materials of webbing, including leather webbing, nylon webbing, polyester webbing and PU webbing. As a kind of special webbing, now TPU coated webbing is popular for outdoor products, and some fashion bags choose TPU coated webbing to replace leather or PU webbing. One important reason is that TPU coated webbing is waterproof and stink-proof. Besides, TPU coated webbing can also has shiny and flat appearance like a mirror.

 

Different from nylon webbing, TPU coated webbing is harder and stronger. TPU coated webbing is the polyester webbing outer coated with TPU. To connect coated webbing, we have several methods.

 

1. Sewing and stitching

 

TPU coated webbing can also be stitched. But we should use needles for leather sewing. Usually TPU coated webbing is harder than leather, so if we choose to connect TPU coated webbing by sewing and stitching, the thickness of coated webbing should below 1 mm.

 

2. Welding

 

Refers to the feature of TPU, TPU webbing can be welded through Radio Frequency. To reach stable effect after welding, we’d better choose thinner coated webbing.

 

3. Punching and riveting

 

This is the most stable connection for TPU coated webbing. Usually the thicker webbing will be punched and riveted. Because stitching and welding is not suitable for thicker webbing.

What is TPU coated rope?

TPU coated rope is a kind of waterproof rope cord. This is the polyester rope cord outer coated with TPU. Within TPU, the polyester rope becomes water resistant and strong.

 

TPU is a kind of plastic material. But contrast with many other plastic materials, TPU is eco-friendly. TPU can be degraded into water when put in moist environment. During the procedure of degradation, TPU won’t produce substances that are harmful to environment, human, plants and animals. Moreover, TPU is stink-proof and will not release hazardous substance when touch human’s skin. Therefore, TPU coated rope is eco-friendly.

 

The inner rope of TPU coated rope is usually made from polyester. Compared with nylon or other textile materials, polyester has better consistency with TPU. Because TPU coated rope cord produced with extrusion technology, the inner polyester rope need to pass through the high-temperature machine. So polyester rope are supposed to be strong enough to endure high temperature. Its shrink range, high-temperature resistance and colour fastness are all being concerned.
