The very antithesis of what someone said above, is Spandex.

Mere presence of Spandex in what you wear ensures that your clothes are just like your extended skin. Also known as Elastane [Europe], it has a versatile and amazing functionality of engineering fabrics with desired elasticity and strength.

At the basic level, one should know that Spandex is underneath the covering yarn, therefore covering yarn material surface will influence the running performance. Typically the covering yarn is Core Spun Yarn (CSY), Single Covered Yarn (SCY), Double Covered Yarn (DCY) and Plied Yarn, and Air covered Yarn (ACY).

Most important requirement for a stretch garment is that apart from Body comfort and fit, it has a natural appearance and recovery from elasticity. While allowing freedom of movement, it shall be breathable and durable. How and where a stretch garment is to be used depends largely on the degree and direction of elasticity, it provides.

The inherent benefits related to Spandex, ensure that it has not only Lifestyle applications, but also has vast and varied technical textile applications. It is used in Sportswear, stretch denim, Bottom wear, Swimwear, Tops [Shirting and Blouses], Intimate wear, Undergarments, Diapers, Socks and leggings.

Spandex has come as a boon to the medical industry with its usage being far and wide across Personal Hygiene [eg. Diapers, training pants], Surgical hose, Surgical Gloves and many more.

Moving beyond the conformist applications, Spandex has made other industries also notice its versatility and is now being widely used in Home Furnishing, Car Upholstery, Cables etc.

It is this cross-category applications of Spandex that the market in seeing a lot of action world-over, in its efforts to introduce innovation and newness, in the most cost-effective way.

India, currently consumes around 6000MT/Year (100% imported) of Bare Spandex. However, against a global growth of 7%, India is growing at 12-14% per annum in its Spandex consumption, led by the growth in organized retail, branded clothing, high GDP growth rate and a relatively positive consumer sentiment. We clearly see the market growing exponentially in coming years as consumers spending power goes further North, their aspirations and lifestyle drives them to seek more and seek better, which is what Spandex imparts. It empowers your clothes with Better and More of you.


Just like any other yarn, Air Covered Yarn also experiences some faults which are caused mainly by two issues – Positional Faults and General Faults. Below are some of the faults that are seen in Air Covered Yarn.

  1. Filamentation:
    1. Positional causes:
      1. Damaged/worn guides
      2. Dirty heaters
      3. Damaged friction discs
      4. Waste on feed rollers/bowl
      5. Misthreading
      6. Mechanical damage to supply yarn
    2. General Causes:
      1. Draw ratio too high
      2. Heater temperature too high
      3. Speed ratio too high
      4. D/Y ratio too low
      5. Supply type/finish unsuitable

Package winding conditions in Air Covered Yarn, should be kept in check to ensure resulting end package is optimum and as per quality standards. These conditions should be kept in control throughout entire Air covered yarn manufacturing process; any slight change in any one of these conditions at any given instant of the process will lead to variation in the end package, which may either result in faults in package or undesirable package hardness.

The package winding variables which are to be kept in constant check are as below:

  • Take-up overfeed,
  • Traverse speed,
  •  Axial/radial disturbance,
  • Taper angle and
  • Oil roller speed

The fashion industry is ever-growing, and new changes are made every day in the trends. The most noticeable changes are, however, at the bottom level; i.e., the yarn. The yarn forms the basis of the texture, strength and durability of the fabric that is manufactured by textile companies. Research in this sector, aims to develop technologies to help make yarns more durable and comfortable.

Amongst other technologies, the Air Spun Yarn is the most noticeable. This is set to revolutionize the future of clothing. Are you wondering why? Read on its features to find out:

•    Spandex core: The textile companies in India use Spandex as core of the Air covered yarn. Upon a spandex core, multiple strands of fiber are spun through air jets.
•    Exceptional softness: The core yarn (Spandex) is intermingled with another filament yarn like nylon or polyester, using compressed air and wound straight in the spool; giving them a powdery appearance and exceptional softness.
•    Most comfortable: With its exceptional softness and light weight, the Air Covered yarn is used in manufacturing comfortable dressing and products like under garments.
•    Strength: The Air covered yarn has more strength and durability than the conventional yarn, making it suitable for manufacturing clothing that lasts longer.
•    Smoothness of Fabric: The Air covered yarn is twisted harder, giving it amazing evenness. The fabric manufactured from this yarn is hence a lot smoother.
•    Lower energy and space needs: It is claimed that the air spun technology consumes less energy per kilogram of produced yarn than other spinning processes. Space needs are 25 percent less than the other methods for the same weight of yarn produced.

It is because of the Air covered yarn being so versatile and efficient that many textile companies in India are manufacturing fabric and clothing from the Air Covered yarn more than the conventionally spun yarn. The fact that it is durable and strong is an added benefit to both the consumers and the producer.
