How can DuPont carpet backing help you?
Broadloom (or wall-to-wall) carpets may be designed using a great variety of techniques:
The plain single color velours, for example, needs a perfect uniform pile regularity. The very fine fibers of DuPont carpet backing allow to place - and to keep - the tufted yarns exactly at the place where the needles entered the backing sheet. No needle deflection by filaments occurs which would eventually lead to a wild irregular pile aspect.
Also, if the tufting step distance interferes with the weft frequency of a woven backing, interference patterns (so-called Moiré-effect) may show up. DuPont carpet backing never shows this effect due to its all-directional fibers laydown.
The printed or pattern-tufted carpet with geometrical pattern design is difficult to process through all manufacturing steps, still keeping the patterns perfectly aligned.
Bowing and skewing may occur if the carpet backing is not dimensionnaly stable enough.
DuPont carpet backing fibers are bonded together at a multitude of cross-over points, so that the overall sheet structure is resistant against bias stretch and hence resisits bowing and skewing.
Another common problem with patterns is the pattern matching issue. This occurs when pattern design is not aligned on adjacent carpet lanes. Use of DuPont carpet backing can overcome this problem.
