The aerodynamic principle

The aerodynamic web forming process with AUTEFA Solutions random card Airlay K 12 stands for an improved MD:CD ratio and a three-dimensional web structure. During the process, the fiber material is opened up to the single fiber, this enables a high versatility regarding fiber choice. Aerodynamic web forming machines from AUTEFA Solutions utilize the aerodynamic principle which results in three-dimensional fiber orientation and total randomization, enabling isotropic web properties. Suitable for all kinds of bonding processes such as thermal-, chemical- or needle-bonding the fabric goods offers a wide variety of applications. The process offers the special advantages when it comes to lighter weights and high loft fabrics.

Material

In the construction, residential and automotive market, efficient thermal and acoustic insulation materials are key factors that contribute to energy saving and to the reduction of natural resources consumption. The increased opening capabilities distinguish itself for a wide variety of different fibers:

  • all kind of man-made fibers
  • Natural fibers (cotton, flax, hemp, sisal, jute etc.)
  • Reclaimed textile waste and shoddy
  • Carbon fibers
  • Glass fibers
  • Fiber properties: 1.7 – 200 dtex; up to 100 mm staple length

Machinery and line components

AUTEFA Solutions Random Card Airlay K12 with the web forming machine V21/R is one of the success stories in the field of aerodynamic web forming. Fed by either a Chute Feeder or alternatively a Hopper Feeder, the Random Card K12 is well suited for a wide range of nonwoven products. Customers chose this proven assembly for a wide range of products or standardized production processes. This aerodynamic web forming line enables fiber opening and randomization in a two-step process. The pre-web forming machine V21/R creates a uniform fiber batt. The following Airlay Random Card K12 provides opening to individual fibers and forms the three-dimensional fiber orientation typical for the aerodynamic process. The FUTURA design enables easy opening and quick access for cleaning and maintenance. The delivery, carding and infeed components are mounted on a linear guiding system.
