Malivlies

from Wikipedia, the free encyclopedia

Malivlies is a brand name for a fiber nonwoven active ingredient, but also for the system and the process on which or according to which this textile fabric is manufactured. When Malifleece methods are in contrast to the stitch-bonding Maliwatt for knitting any threads used, but only fibers of a nonwoven to preferably transversely-oriented fiber layer. At the work site, the fleece (the paneled card pile) is pierced with the compound needles. Insert plates prevent the fleece from moving forward. When the compound needles move back, fibers lying across the front of the fleece are caught by the needle hooks, enclosed by the closing wires and pulled through the fleece. A half stitch is still hanging on the needle shaft from the previous work cycle. The newly acquired fibers are pulled through this, after which the half stitch is thrown off via the needle point with the help of the sinkers (knockdown bar). This creates a knitted structure on the back of the fleece.

Depending on the type of system, the maximum working widths of the systems and thus the Malifleece products are 2900 mm, 4150 mm and 6150 mm, whereby a stepless reduction is possible. The weight per unit area of the Malivlies products can be 120 - 1200 g / m². Polyester, polypropylene, viscose and tear fibers are used as fibers. The machine fineness (number of needles / 25 mm) is 0.5 - 24. The machine fineness and the stitch length, which can be between 0.5 and 5.0 mm, are used to control the consolidation intensity. The performance of the systems is up to 1370, 1960 or 2905 m² / h, depending on the conditions of use and article specifications.

Malifleece is used for coating substrates, linings (shoe linings), carpet backing, packaging material, insulation materials, but also for utility textiles.
