Covered Yarn

When talking about 

covered yarn

, one talks basically about elastane yarns that have at least one more yarn wrapped around. Covering however is not exclusively applied to elastane, sometimes also fine wires are covered.

There are two purposes of covering a yarn: one needs an elasticity which normal textile yarn cannot provide while one would still like to keep the apperance of the textile yarn. This is the case for covering elastane where most often a textile Polyester / Polyamide / ... is wrapped around the elastane core.

Covering a yarn can also be in order to hide something. This is most often the case when covering fine wires. The yarn that is wrapped around gives the looks whereas the core (the fine wire) still provides the functionality (like conductivity).

Single covered yarns are yarns where a second yarn is wrapped around a core yarn.

Double covered yarns are yarns where two separate yarns are wrapped around a core yarn.

The second layer of wrapping mainly serves to compensate the twist direction of the first layer.

With air covered yarns, the outer yarn is intermingled around the core yarn.

A non-elastic multilfilament yarn can for example be intermingled with an elasthane yarn that is in the core. This construction can be of help in certain embroidery applications.

In the example of Elasthane, a non elastic yarn gets wrapped around a twisted elasthane yarn. The elasthane is thus fully covered by the non elastic yarn which leads the yarn as a whole to have the look as well as the haptics of the non elastic yarn. However, the perks of elasthane are still to be noticed when wearing a fabric that is made out of such a core spun yarn by a much higher wear comfort for example.

Functional yarns that meet a growing number of customer demands

Technical yarns are materials with special resistance. Be it high chemical resistance, tensile strength, flame retardancy or functionality such as electrical conductivity. What if a piece of clothing would not only look good on you but would also keep you warm? What if it would also be water-repellent? And what if it had even more features, such as being wind-proof, able to maintain air circulation or act as an antibacterial layer? In today’s textile market, all of these attributes can be found, often even in combination with one another. This is the result if advanced technology becoming available in the textile industry, mainly in the form of functional yarns.

The advantages of functional yarns over classic ones

Functional yarn is responsible for the development of a whole range of new clothing categories that have not been known before. One of those categories is the entire line of athletic clothing, from warm-up clothes made from water-repellent fabric to stretchable sportswear that doesn’t falter and snaps back into shape when fast, dynamic movements are performed. The textiles worn by athletes in all kinds of sports often come with a range of other advantages apart from their elasticity and all of those have been made possible by the use of specialized yarns.
