Woven Polyester Cord Strapings & Lashings
The first US commercial polyester fiber production was by Dupont Company in 1953. At that time, the polyester fibers were primarily used for fabric production. There was a growing movement to develop plastic strappings to replace the steel strappings that were widely used then.
Sometime later in the 1950s, the glue bonded polyester cord strapping was developed. At the early stage, these cord strappings were used for simple bundling of goods.T he woven strapping was also developed at about the same time frame. In the 1960s, the composite strapping was developed. By the 1990s, cord strappings have made major technical advances to largely replace steel strappings in most applications.
Types of Cord Strappings
There are 3 main types of polyester cord strappings depending on their manufacturing processes:
Glue-Bonded Cord Strappings
The linear polyester yarns are held in the band by hot-melt glue.T his strapping has a soft and tacky feel. Comes only in natural color.
Woven Cord Strappings
These are woven from high tenacity polyester yarns and can come in any colour. The woven strapping is soft, lightweight and flexible.
Composite Cord Strappings
The linear polyester yarns are co-extruded with polyethylene to produce a stiff strapping band.Only comes in natural colour.
The 3 types of cord strappings are interchangeable in usage. It is just a marketing strategy by manufacturers to differentiate themselves in order to compete better. An individual customer may have a preference for a particular type based on his individual opinion or usage experience
