Do You Know What Lycra Fabric is, & How it is Actually Made?


What Is Polyester Lycra Fabric?

         Lycra is basically a luxury name of elastane – a highly elastic synthetic fabric. Either call it Spandex, Lycra, or elastane, it’ll still be the same material. This fabric can stretch to 5-8 times their regular size.

In historical terms, this fabric was first introduced by DuPont Corporation in 1950s, be that as it may, it would not exist if polyurethane had not been concocted by IG Farben during the 1930s in Nazi Germany. Currently, Polyurethane represents base material for many different plastics, and the same basic chemical synthesis methods are used for making Lycra which is already make other polyurethane-based plastics.

Just like other polyurethane materials, Lycra fabric is also a polymer itself, it means it contains long chains of monomers which are connected with special type of acid. In contrast to numerous different sorts of manufactured textures, Lycra is profoundly impervious to warmth, and it was immediately perceived as an amazing expansion to warm touchy engineered materials like polyester and nylon.

How Is Lycra Fabric Made?
The making of polyester Lycra fabric undergoes following stepwise procedure;

Step 1:  Producing Prepolymer
This step is done by mixing diisocyanate monomer within a special type of reaction vessel’

Step 2: Chain extension Reaction
When the dry spinning method is used, this prepolymer is then reacted with diamine acid

Step 3: Diluting
Next, this solution is diluted with a solvent to make it thinner and easier to handle, and then placed inside a fiber production cell

Step 4: Extrusion
This cell twists to deliver strands and fix the elastane material. Within this cell, the solution is pushed through a spinneret

Step 5: Heating
These fibers are heated within a nitrogen and solvent gas solution to form liquid polymer into solid strands

Step 6: Twisting
The solid strands are then bundled together as they exit the cylindrical spinning cell with compressed air device that twist them

Step 7: Finishing
In this step, the magnesium stearate or another polymer is used for treating elastane material as finishing agent

Step 8: Weaving
In conclusion, the Lycra yarn is moved to an enormous spool, and it is transported out to a material assembling plant

This entire lengthy procedure of making polyester Lycra fabric make it worth using for multiple textile uses. However, if you ever wish to approach any reliable, and reputable PolyesterLycra Fabric supplier, then Xiaomin textile should pop first in your mind, especially if you’re willing to approach as consumer to expand your business

Working, Pros & Cons of Piezoelectricity – Something Worth Learning!

           Piezoelectricity – The term gives hint of buzzer device, right? Well, not necessary, it is more than only use of device. The thing is, no explanation of piezoelectric effect would be complete until and unless we don’t uncover for what other work the piezoelectric devices are applicable to.   A big thanks to incredible development of piezoelectric manufacturers who provide us an immense variety of products using piezoelectricity apart from buzzers. Here, you can imagine how the rise of piezoelectricity in electronic devices is growing at high scale. Hey, wait, do you even know what piezoelectric means and how Piezoelectric Material Works? Here we go;   What Does Piezo Mean & How does Piezoelectric Material Work? The term “piezo” has been derived from an ancient Greek, according to which it indicate an action of squeezing, pushing, and pressing. The piezoelectric effect on other hand is an ability of specific materials (like tourmaline, quartz, topaz
