Lycra, fibre, K, Spandex, all these appellations refer to one and the same synthetic fiber after the polyurethane is very well known in the world textile : theelastane. Known for its virtues elastic, this item is not all the same represented only in low amounts in our ranges of clothes ethnic. That gives marriage cotton-elastane ? What are the advantages of this combination ? Overview on this subject in this article.

The spandex, the asset extensible that it takes a garment ethnic

Before we go any further in this article, it is important to understand the elastane and its features.

What should you know about the elastane ?

Developed in the 50s by the scientist Joseph C. Shivers, the elastane is a textile fibre resulting from a chemical process including the polyurethane, a synthetic rubber. It will be necessary to wait until 1962 for its manufacture becomes industrial, and that it is spreading in the world of fashion.

It grants him a major advantage : its elasticity and its ability to stretch up to 7 times its length. The real feat in this flexibility lies, however, in the special ability of the fiber to recover its original appearance.

Why is he represented in low quantity on the clothing ?

Spandex, the expandable asset of an ethnic garment

On the label, it is not rare to see compositions of textile including spandex. Mixed with cotton, wool, polyester and viscose, it is quite often that 3 % of the composition. There are two reasons for this.

On one side, the efficiency of the spandex is so important that a small amount is enough to provide the flexibility sought in the garment.

On the other side, it is a synthetic material that should be used in low dose to avoid that ecology takes a shot. This is due to the dimethylacetamide is present in the spandex.

The advantages of combining the elastane with the cotton in the clothes ethnic

If the virtues of cotton, as a fabric of natural origin, is no longer to demonstrate, the elastane to him, has yet to be proven.

The advantages of elastane

- Lightness : elastane is a fabric higher end and more robust than a thread of natural rubber. Due to this advantage, the preference is for its use in clothing, ethnic close to the body, sportswear, and underwear.
- Elasticity : The clothes with elastane does not deform, regardless of the movements that you do, simply because of the elastane has this gift to return to its original shape.
- Hydrophobia : spandex is a material that absorbs weakly and water and offers a good resistance to chemical attack. This aspect facilitates the maintenance of the garments ethnic with elastane, because this hydrophobia protects the tone of the colors and prints.

Why mix the cotton and elastane ?

Although it has many virtues, the cotton is not elastic in itself, especially when it is woven. Where the interest of the blend with elastane fibres.

The cotton jersey

A name inherited from the Middle Ages, the jersey is a knit technique by which make fabric from fibre. Unlike woven fabric, the jersey has a fine mesh easily recognizable by their paces in the wave backwards and a small V at the place. As any material or knitted, these meshes are slightly stretchy and can stretch up to 5 to 8 % of its length.

The jersey cotton is a comfortable fabric, soft and breathable. Nevertheless, there is a variant which incorporates elastane which has a better elasticity. The jersey cotton-elastane comes in several types of thickness and is applied in the manufacture of casual wear, casuals and sport. This is the type of jersey that can be found mostly in our collection of t-shirts ethnic.

The combination of comfort, strength and tone

Cotton has many advantages, including its soft feel, the character , hypoallergenic, its natural fibre and its high permeability to air, of the advantages which ensure a comfortable single port. However, there is bound to be a few drawbacks, citing their tendency to shrink in the wash and dulling of the colors with time.

These disadvantages are wiped out by the elastane fibres. When the cotton shrinks, the elastane is addressed by stretching and returning to its original shape. In addition, the elastane preserves the colors and the tone of the grounds due to its ability to resist to water and chemical agents are present in laundry products. No need to remind how much a fabric composed of 97 % cotton and 3% elastane which has a great ease of maintenance.
