Fillattice Stretches Its Reach Globally
Linel® elastic fiber production has increased steadily to meet growing demand.
By Eric Vonwiller, Technical Editor
he Fillattice Group (Fillattice SpA, Italy, and Fillattice Inc., Charlotte., N.C.) is a
dynamic Italian industrial corporation that has become one of the most important producers of
elastomeric fibers, stretch fabrics, covered yarns and textile machinery.
In the aftermath of World War II, the company branched into the production of rubber yarns derived from latex and became one of the world leaders in this field.
In the ’70s Fillattice Group launched Linel®, a polyurethane-based elastic fiber. The success prompted the establishment of the Lineltex plant to produce stretch fabrics.
An international network of production and distribution facilities was installed as well. The demand for Linel in the textile sector, and the development of new applications, have driven the Fillattice Group to increase its production capacity steadily in the past years.

The Wet-Process Yarn
Linel is a continuous polyurethane
fiber composed of filaments. It has a high elasticity and remarkable strength of recovery without
being constrictive. It is produced through a wet-processing technology that provides the yarn with
the advantage of leaving it with the highest elongation.
Linel is recognized on the world market as being one of the best elastomeric fibers due to its technical characteristics and high quality levels.
Linel’s high stretch, remarkable softness and silky hand allow the production of fabrics with exceptional qualities of comfort and stretch, wearability, softness and adherence.
Typical applications for Linel are outerwear, sportswear, swim-wear, underwear, hosiery, medical and industrial articles, furnishings and many other applications.
Linel is available in a broad range of counts, from 11 dtex to 1,880 dtex on spools and on beams. Linel is produced in a “semi-clear” version in a count ranging from 44 to 1,880 dtex. It is also produced in a “semi-dull” version to avoid appearance problems of too high luster in certain garments.
The production of this fiber is carried out at the Fillattice 2 and FIES production plants through “wet-spun” technology that enables Linel to have some technical characteristics that are unique amongst the world’s best elastams.
Linel has a high elongation of up to seven times its original length, and due to its great recovery, it returns to its original length as soon as the tension is released.
Linel distinguishes itself from other elastams due to its exceptional regularity which enables the creation of extremely fine, even fabrics. Because of this fact some of the most recognized garment manufacturers in the world choose fabrics with Linel, especially in the swimwear and sportswear field.
The Dry-Process Yarn
Linel Comfort® yarn is produced from
fiber manufactured at the new Fillattice 3 plant. The fiber itself was created by Fillattice’s
in-house research and development team and uses the innovative “dry-spun” technology.
Fillattice claims that Linel Comfort has, in addition to the standard properties of other elastams, exceptionally well controlled and pleasant compression, good adherence and comfortable wearability. It is for these reasons that Linel Comfort is used predominantly in ladies hosiery and woven materials.
Linel Comfort is produced in a clear and dull version from 11 dtex to 235 dtex.
Applications And End-Uses
Linel in its original condition, “
bare Linel,” as Fillattice calls it, can be used on circular knitting machines or weaving machines
equipped with positive feeders that control the tension of the elastam, help the unwinding of the
yarn from the package and ensure constant conditions for the yarn.
The main uses of bare Linel are in circular knitting for casual wear and underwear; in warp knitting fabrics for swimwear, sportswear, underwear, corsetry, narrow fabrics and stretch laces; and finally, the application in ladies hosiery.
Covered Linel is used in applications where bare Linel cannot be used. It enhances the processability by increasing friction resistance. Furthermore, it permits more control over the maximum elasticity of the fiber, allowing a very controlled feeding of the yarn on the knitting machine.
Covered Linel can achieve very prestigious looks in fabrics. Single- or double-covered yarns are mainly used for high-quality tights, narrow fabrics, woven fabrics like denim and gabardine, and circular and flat knit goods.
In intermingled yarns, a multi-filament continuous yarn covers Linel. Through an air-jet process, intermingling the cover fibers in a random manner creates a non-uniform cover of Linel. This yarn is used in the circular and flat knitting, woven fabrics, and men’s hosiery and sports socks.
Other versions of covered yarns are core-spun yarns that are used in fabrics of particular high quality, and twisted yarns, where Linel is twisted together with other yarns.
Linel and Linel Comfort are always used with other natural or synthetic fibers in order to give the final product elasticity and comfort. The percentage of Linel in the final product depends on the demanded characteristics of the product.
For example, between 2 percent and 4 percent are usually used in a woven fabric, 20 percent are used in warp-knitted fabrics, and up to 25 to 30 percent are used in ladies hosiery.
Some technical fabrics up to 35- to 40-percent Linel and Linel Comfort may be used.
As already mentioned, Fillattice has been steadily increasing its production quantity. The
strongest markets for Linel and Linel Comfort are Europe, the United States and the NAFTA
countries, South America and the Southeast Asia.
Fillattice has made a worldwide commitment to serve its customers with the best possible yarns, tailored to their needs. The company understands that this is a consumer driven market and develops its products to fulfill the demands of comfort, durability, and easy care.
Fillattice’s elastic fibers are offered in a broad range of yarn counts and fashionable colors.
