Lower raw material consumption for the same performance
Processability of all types of fiber materials including recycled fibers as well as natural and synthetic fibers
Lower cost of machinery, lower energy consumption, smaller installation and utilization surface when compared with a traditional production line consisting of crosslapper and needleloom or sprayer with drying oven
Easy recyclability and good hygienic properties when compared with polyurethane foam
Applications Of Fabrics
Mattress / furniture industry - replacement for polyurethane foam
Filtration - both wet and dry filtration
Automotive - struto is proving an excellent structure for various types of applications
Filling material in blankets, pillows and sleeping bags
Thermal insulation
Acoustic insulation
Children's play area
Compressional Properties And Resilience Of Fabrics
Due to vertical position of fibers, the struto® textiles show outstanding compressional rigidity and a high degree of recovery after repeated loading
Compressional curves of various highloft materials are compared in figure 1
Elastic recovery of fabric after repeated loading is compared with that of polyurethane foam and a conventional highloft fabric in figure 2
Can Be Used As Filtration Media
The efficiency of filters using this system as the main component show excellent qualities for collection of particles of all types while giving very low pressure drop figures
Higher efficiency when compared with other materials: when tested with dust particles of the same size, this system shows consistently higher efficiency figures than virtually any other media
Superior dust holding capability: the structure of this system allows it to hold a much larger amount of dust than other materials as has been shown in a number of tests
Very low pressure drop: the system structure is extremely organized and allows air to pass much more freely through it than conventional structures but still traps dust particles; the result is a very low-pressure drop but still excellent dust holding capability
Process Description
A properly mixed blend of basic and bonding fibers is processed by a carding machine (1)
The carded web is formed using vertical lapper (2) into a fiber batt on the conveyor belt of the through-air thermobonding chamber (3)
After passing through the chamber the fabric is cooled and wound up (4)
A supporting layer (5) can be brought from below onto the conveyor belt of the bonding chamber; the layer is then linked together with the system’s textile during the bonding process; thus, the composite material is produced in one process
