75D 4 way spandex with sliver printed film for sports cloth fabric
|Type||75D 4 way spandex|
Spandex. Spandex is a lightweight, synthetic fiber that is used to
make stretchable clothing such as sportswear. It is made up of a
long chain polymer called polyurethane, which is produced by
reacting a polyester with a diisocyanate. The polymer isconverted
into a fiber using a dry spinning technique.
It's also called stretch fabric.
Stretch fabric is a synthetic fabric that stretches. Stretch
fabrics are either 2-way stretch or 4-way stretch.
2-way stretch fabrics stretch in one direction, usually from
selvedge to selvedge (but can be in other directions depending on
the knit). 4-way stretch fabrics, such as spandex, stretches in
both directions, crosswise and lengthwise.
Stretch fabrics evolved from the scientific effort to make fibres
using neoprene. From this research, in 1958, commercial stretch
fabrics ("elastomerics") such as spandex or elastane (widely
branded as "Lycra") were brought to the market.
Stretch fabrics simplify the construction of clothing. First used
in swimsuits and women's bras, fashion designers began using them
as early as the mid-1980s. They entered the mainstream market in
the early 1990s and are widely used in sports clothing.
