Why synthetic fibers?

Focus on safety

DELIUS has a long tradition as a textile manufacturer and knows the properties of cotton, linen and silk very well. After all, these were produced and marketed from 1722 until the end of the 20th century. All these natural fibers have advantageous properties for the clothing and home textiles market. They absorb moisture, are breathable, durable and have an appealing look. And they are renewable raw materials, which are of course also biodegradable.

With the decision to focus entirely on the contract market, the decision was also made to only include fabrics with permanent flame-retardant properties in the collection.

But why?

Object fabrics are manufactured for use in public buildings. And one thing is paramount here: safety. Hotels and cruise ships should provide a safe home away from home, cinemas and theaters should be a place of relaxation and enjoyment and our children should be able to play and learn safely in schools and kindergartens.

And so far, only fabrics made from polyester FR and Trevira CS offer this level of safety. Here, the flame retardancy is firmly anchored in the fiber and remains permanent even after repeated washing. Fabrics can also be made flame-retardant with a finish, but this finish is lost after a few washes. Synthetic fibers are more robust and stable than natural fibers and therefore have a long service life. High color fastness also helps the fabric retain its attractiveness and beauty for longer, meaning it doesn't need to be replaced as often.

Recyclable

All articles made of 100% polyester FR or Trevira CS are unmixed and can be easily mechanically recycled. Even after use, they make a valuable contribution to the circular plastics economy and are an important aspect of resource and environmental protection.

What is polyester FR made of and how is it produced?

Polyester FR or Trevira CS are made from crude oil. Less than 1% of the crude oil extracted worldwide is used to produce synthetic fibers.

Polyester fiber fabrics (PES for short) are produced from plastic using the melt spinning process. The base material is converted into a viscous melt under the influence of heat. This is then pressed through spinnerets and cooled again. This produces endlessly long fibers, the so-called filaments. Depending on the nature of the nozzles, the fibers can be finer, rounder or more angular. They are the starting point for a wide variety of fabrics.

Synthetic fibers offer a major advantage compared to natural fibers. They can already be adapted to future properties during the manufacturing process.

The additional function of the flame-retardant effect is already achieved at the polymer stage, which makes subsequent finishing of the textile, as is necessary with materials made from natural fibers, superfluous. With Trevira CS and polyester FR, the flame-retardant properties are firmly anchored in the fiber raw material and are not lost through external influences such as washing, ageing or abrasion. If desired, a dye can also be added directly to the spinning mass. This eliminates the need for complex dyeing processes, which consume and contaminate a lot of water.
