Nonwoven fabrics for multiple applications

Nonwoven fabrics for multiple applications

 

Nonwoven fabrics can have multiple applications and Eurospuma offers a wide variety of customization options. We work with solid, hollow, hollow with four channels and hollow conjugated and siliconized fibres. What is the best solution? Find out with our help...

 

At Eurospuma, before producing a non-woven fabric, we come up with the formulation according to the type of filling intended by the customer or the final application. There are some characteristics to consider in this process and that will define the type of non-woven fabric that will result from it and, consequently, its application.

 

Decitex
Decitex (dtex) is the unit that determines the proportion of fibers, i.e. the weight (in grams) of 1000m of yarn or filament. The higher the decitex, the rougher the filling. For example, fibers with 1.5 dtex are thinner and better for compaction because they are easier to close. A fiber with 30 dtex is thicker and, consequently, bulkier.

 

Length

A fiber can have different lengths, which will influence the carding process and the formation of clusters. For example, a short fiber allows better distribution of filaments and better carding. In the case of clusters, it allows you to close the fiber better.

 

Finish

The fibers can have two finishes: siliconized and dry. Siliconized fibers have a silicone coating, which makes the filling slide better. The more slippery the touch of the fiber, the more comfortable it becomes.

 

Elasticity

There is a type of fiber that has an elastic component that makes it more comfortable. For example, our Spring brand of fibres. The more elastic a fiber, the more comfortable it becomes.

 

Section

The section is the inside or profile of a fiber filament. A fiber can have a solid or hollow section (1 channel, 4 channels, etc.). Hollow fibers have more volume, are softer and more resilient than solid fibers. In addition, they allow better thermal insulation.

 

Crimp

Crimp refers to waves or bends introduced into the fiber, per unit of length. The goal is to give cohesion and volume to the fiber and facilitate its carding. The more creased the crimp, the greater the fiber's resilience, and its resistance to compression. There are three types of crimp: Sharp, waved, and helical.
