Application of an elastomeric yarn to improve the quality of the fabric
Artificial fabrics, natural materials, andalso synthetics without additives have a reduced elasticity and do not stretch at all. Products from them crumple, stretch, it is almost impossible to restore their original appearance. In addition, in such clothes it is not very convenient to move. To improve the performance of the tissues, synthetic fiber-elastane is added to their composition. In Canada and the US it is called spandex, which translates to "stretch".
From the history of origin
For the first time, a synthetic elastomeric thread appeared in the late fifties of the last century thanks to the invention of the American scientist J. Shivers, working at DuPont.
In Japan, materials made of elastomer threads are produced under the brand "Dorlastan".
Material specifications
Elastan is a practical and bright fabric, from whichsew soft, comfortable clothes. She rushes for a long time and does not crumple. The main quality, thanks to which the material has gained popularity, is high extensibility. The length of elastane fibers can be increased up to 5-8 times.
In addition to elasticity, spandex has a number of important properties:
- Elasticity - after stretching returns to its original form.
- Strength - not afraid of loads, does not change the characteristics under the influence of water.
- Subtlety - the thickness of elastomeric threads is minimal, so that they can be woven into any fabric.
- Softness - material with the addition of elastane is flexible, easily draped with soft folds.
- Lightness - the use of the material practically does not change the overall weight of the canvas.
Elastomeric filament in the composition of synthetic andnatural fabrics allows you to get breathable, elastic, comfortable and pleasant to the touch materials. Clothing from such a fabric does not crumple, it retains its original appearance for a long time, does not wear out and does not bind the movements.
Application of products made of elastomeric yarns
As a rule, the elastomer is produced in the form of threads,wound on the spool. Usually cotton, linen, viscose or polyamide materials are added to it, since pure polyurethane is not used in practice. This combination increases the strength and elasticity of finished products, making their appearance more attractive. This is the reason for the use of an elastomeric thread for beading. At the same time, wear resistance is noted. Clothes are more comfortable for a person, do not cause irritation and dry skin.
The lack of spandex is an instability toexposure to ultraviolet and water with a high content of chlorine. In addition, threads with elastane can become a source of allergy, so when buying it is worth paying attention to the composition of the fabric.
Clothing with the addition of elastomeric fibers
To the source material it is recommended to add from5 to 15% elastane. The most popular combination of polyurethane fibers with viscose - from the resulting combination make a sports uniform and clothes for everyday life. In addition, from viscose with elastane make tight dresses for cocktail parties and celebrations.
Increasing the percentage of elastomer to 20-30% provides the material with increased wear resistance. Most of sportswear, swimsuits, stockings and pantyhose are sewn from it.
For festive dresses and carnival images inthe composition of the fabric besides lycra include lurex. Elastomer yarns (pictured below) are also used in the production of jeans clothes - in addition to the cotone, about 5% of polyurethane filaments are added.
Proper care of clothes
The rules of care for finished products depend on what is included in the fabric besides elastane. Recommendations are indicated on the label:
- Wash clothing in a delicate wash or manually. The water temperature should be below 40 ° C.
- Polyurethane yarns have the ability to burst, so when squeezing clothes, do not strongly twist it.
- "Aggressive" powders and bleaches quickly destroy matter, so their use must be abandoned.
- To keep the shape, dry the products in a horizontal position.
- It is recommended to iron the fabric at temperatures up to 150 ° C.
