Dry spinning is the most efficient and widely used way of manufacturing spandex filament. At Indorama Industries Limited we have since the beginning used “Dry-spinning” to manufacture our spandex yarn.
In simpler terms “Dry spinning” of spandex is explained as below:
1. In this process initially raw materials are dissolved together to form a solvent which is then used for further process. The dissolution takes place in presence of a volatile solvent, which evaporates when heat is applied to it
2. The solution produced from above step is then filtered to make it suitable for further processing

May 20th holds an important place in the history of “Jeans” as birthday of “Blue Jeans”. On this date in 1873, Blue Jean made its debut, as one of the American companies received a US patent for this.
This year, Sunday May 20th marks 145th Birthday of Blue Jeans.
Jeans is iconic garment made by “Denim” fabric, which is sturdy cotton warp-faced fabric having white filling in reverse direction. Jeans is generally characterized by strength, tear resistance and visually appealing blue shade, which fades each time the garment, undergoes laundering.
Changing fashion styles and attitudes altered the look of the blue jean over time, but until recently, the blue jean had remained true blue to its cotton origins. The recent influx of man-made fibers into blue jeans is not a good fit for many consumers and could affect the care, wear and expected five-year longevity of their beloved blue jeans.
The history of denim as being all cotton, comfortable and crazy durable earned it a spot quickly with folks who work hard physically like farmers and workers in the industrial spaces like miners, mechanics, shop floor workers.
The denim fabric from which jeans are made is very strong, rugged and has good tear resistance, thus protecting the wearer in these work profiles and lasting longer as required by the professional requirements and economic conditions.
