Spandex fibers history
Spandex fiber
history:
In previous times,
only rubber was used as the elastic fiber in textiles. To make yarn from rubber it
needed to be cut as sheets. After that process development help to dissolve
rubber and then make yarn. Then it was used as a core inside the cotton or
other types of yarn. The yarn was named latex. This yarn was limited.
These are heavyweight, and if we dye
the fabric then the fabric does not absorb dyes well. If also it absorbs dyes
but if we stretch then it also showed the fiber color. In 1947 Herbarlien
patent corp. produced a yarn that had elasticity and they named Helenca. But
this yarn also does not have enough elasticity because it was not able to make
crimp, coil, and curve. Also, there was not enough elasticity. It was
0.25 to 0.50 % more elastic than rubber.
In 1947 Dupont company
produced one kind of elastomeric yarn as per their invention. They named this
fiber K. For some experiments they started to sell this yarn in
1958. After that, they got a good result and changed the K fiber name and again
named Lycra. Then spandex fiber was produced in huge production as Lycra
trademark in 1962.
Day by day it was
increased the demand for spandex fiber and Globe Manufacturing company take a
plan to produce spandex yarn and produced Glaspan spandex in 1963. This company
produced two kinds of spandex, one is Glaspan and another is Clearspan. Both
are good in quality.
