So what exactly is spandex and what are its advantages and disadvantages? Today I will help you unveil the magical veil of spandex.
What kind of fabric is spandex:
Spandex It is also called elastic fiber due to its extremely high extensibility. In addition, it has similar physical properties to natural latex yarn, but it is more resistant to chemical degradation. Its thermal stability generally has a softening temperature higher than 200 degrees Celsius. Spandex The fabric can withstand sweat and salt, but the fabric is prone to fading after exposure to the sun.
The biggest feature of spandex is that it is extremely elastic and can be stretched 5 to 8 times without damaging the fiber. Generally, spandex needs to be blended with other fibers to blend chemical fibers. The fabric cannot be woven alone, and most of the proportions will be less than 10%. For swimwear, the proportion of spandex in the blended chemical fiber fabric will account for 20%.
Advantages of spandex fabric:
As mentioned earlier, it has excellent extensibility, so the shape retention of the fabric will be very good. The spandex fabric will not leave wrinkles after folding.
Although it is not as soft as cotton, the overall feel is okay. The fabric is also very comfortable when worn, and is especially suitable for the production of close-fitting clothing.
Spandex is a type of chemical fiber. It has properties such as acid and alkali resistance and aging resistance.
Good coloring performance also prevents the spandex fabric from fading under normal use
Disadvantages of spandex fabric:
The main disadvantage of spandex with poor hygroscopicity. Therefore, its comfort level is not as good as natural fibers such as cotton, linen, and silk.
Spandex cannot be used alone. It is usually blended with other fabrics based on the purpose of the fabric.
Its heat resistance is relatively poor.
Spandex maintenance tips:
Although spandex is sweat-resistant and salt-resistant, it should not be soaked for a long time or washed at high temperatures, otherwise the fibers will be damaged.
