A major focus of the new equipment is to improve operation efficiency, web quality and uniformity with positive effects on all staple fiber bonding processes. All these elements belong to the “Dilo – Isomation” process and aim at an even web mass for reduced fiber consumption as raw material is the biggest cost factor in textile production.
One machine contributing to this process is the dosing opener DON manufactured by DiloTemafa, which provides an intense opening of the fiber material. It delivers the fibrous material continuously and homogeneously to the card feeder.
Another effort to increase productivity is the card feeder MultiFeed designed by DiloSpinnbau, which is available in working widths up to five meters. This machine using a “twinflow” infeed to increase homogeneity offers a capacity of over 400 kg/hour/m of working width when processing 1.7 dtex fibers. The use of a “twinflow” infeed results in a more homogeneous flock mass flow.
The MultiCard, also designed by DiloSpinnbau, has a high production availability due to its easy and fast accessibility for cleaning and maintenance work. It handles the full range of fiber fineness and length with a web speed potential of up to 200 meters per minute making it an economic solution for cross laid nonwoven production.
In addition, Dilo crosslappers providing infeed speeds up to 160 meters per minute (DL series) may be equipped with the redesigned Webguide from DiloMachines, which also improves felt homogeneity and results in fiber savings.
DiloMachines offers a wide range of vertical and horizontal crosslappers, which ensure high layering precision based on excellent web control. The portfolio of DiloMachines includes the complete range of needlelooms, from a single board needling on one side up to two boards from each side, plus structuring and patterning options. Endless felt tubes can be needled and also wide working width belts for papermachine clothing applications. The development of needlelooms continues. Elliptical and circular needlebeam movements are used to control drafts in the needling zone and to provide high speed felt production especially in the low weight range.
