The influence of calendering parameters on performance properties of needle-punched nonwoven cleaning materials including r-PET fiber

Analysis of the effect of production parameters on sound absorption and abrasion resistance performance of needlepunched nonwovens for automotive carpet applications using Taguchi method

“…It was obtained that the nonwoven samples having a lower weight ratio (10%) of LMPET in the blend showed lower fiber loss percentage compared to the samples having a higher weight ratio (20%) of LMPET. Increasing the weight ratio of LMPET in the blend more than a critical value showed a negative effect on abrasion resistance since more bonding sites may have occurred and more number of bonded fibers may have abraded from the surface together during the test [17]. The fiber loss decreased when the areal density increased (Figure 9), since a higher number of fibers per unit area led to more cohesion between the fibers which would be more difficult to abrade [17].…”

The fiber loss decreased when the areal density increased (Figure 9), since a higher number of fibers per unit area led to more cohesion between the fibers which would be more difficult to abrade [17]. In addition, the third effective independent variable on abrasion resistance was penetration depth (Table 13).…”

“…It was reported that the consolidated surface of sandwiched-needled fabrics, with more number of fibers per unit weight, resulted in better Martindale abrasion resistance compared to the needled-calendered fabrics prepared from only 6 denier hollow polyester fibers. In another study [17], it was found that calendering process after needlepunching improved the Martindale abrasion resistance. In the study of Atakan et al.…”

Development of nonwoven automotive carpets made of recycled PET fibers with improved abrasion resistance

“…They observed that the higher the fabric mass per unit area, the better was the abrasion resistance achieved. Çinçik and Gunaydın [19] studied calendaring effects of needle punched nonwovens on different properties including abrasion resistance and found that additional calendaring process after needling increased the abrasion resistance.…”
