Woven Polyester Cord Strappings & 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.
Some time later in the 1950’s , the glue bonded polyester cord strapping was developed .At the early stage , these cord strappings were used for simple bundling of goods .The woven strapping was also developed at about the same time frame.In the 1960’s , the composite strapping was developed .By the 1990’s , 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 band by hot-melt glue .This 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 diffentiate themselves in order to compete better. Individual customer may have a preference for a particular type based on his individual opinion or usage experience
