“…The porosity (P; %) of the samples were computed using bulk density of the nonwoven structure (dn; g/cm 3 ) and density of the fiber forming the structure (df; g/cm 3 ) as follows. Since the samples were constituted from different fibers, the fiber densities were also calculated based on a weighted average [97]. The densities of r-PET, bicomponenet PET, PP, PBT were considered as 1,35g/cm 3 , 1,38g/cm 3 , 0,9g/cm 3 , 1,35g/cm 3 , respectively during calculations [98][99][100][101][102].…”

The sound and heat insulation are among the most important concerns in modern life and nonwoven composite structures are highly effective in noise reduction and heat insulation. In this study, three layered nonwoven composite structures composed of recycled polyester (r-Pet) based thermo bonded nonwoven outer layer and meltblown nonwovens from PP and PBT as inner layers were formed to provide heat and sound insulation. Fiber fineness and cross section of thermo bonded outer layer, fiber type (PP/PBT), areal weight (100/200g/m2) and process conditions (calendared/non-calendared) of meltblown inner layer have changed systematically and the influence of these parameters on thickness, bulk density, air permeability, sound absorption coefficient and thermal resistance of composite structures were analyzed statistically. Also; the results were compared with composite structures including electrospun nano fiber web inner layer and with structures without inner layer. It was determined that sound absorption coefficients ranging between 0.77-0.98 for moderate sound frequencies and 0.99-1 for higher sound frequencies were acquired with developed nonwoven composite structures. Besides, higher sound absorption coefficients were obtained as 0.71 and 0.74 for low sound frequencies such as 800 and 1000Hz, respectively. As a result of this study it can be concluded that developed nonwoven composite structures that provides better sound absorption coefficients and similar thermal conductivity values compared to previous studies and materials in the market can be used as insulation material in required areas.

“…Basically, polyester fabric has high abrasion resistance and good tensile strength when compared with natural fiber. 68 Having a high number of fibers due to the high mass per unit area uplifts interaction and frictional forces between a high number of fibers which turn the fabric more abrasion-resistant. The presence of polyester fiber in the fabric may be one probable reason to display excellent abrasion resistance.…”

Denim-like knitted fabrics are getting popular for their several favorable properties, such as flexibility, comfort, and ease of manufacturing. This study aimed to manufacture knitted denim fabrics made from various blend ratios of cotton, polyester, and spandex fibers. Seven fabrics with a fiber blend ratio ranging from 95% cotton/5% spandex to 30% cotton/65% polyester/5% spandex were developed using a weft circular knitting machine. First, the twill effect of the knitted denim fabric was brought by following a cross terry knitting structure to produce each fabric sample of this study. After that, the fabric performance was analyzed by characterizations, such as areal density, pilling and abrasion resistance, dimensional stability, stretch, and recovery, tear strength, bursting strength, air permeability, vertical wicking, liquid absorbency capacity, and different colorfastness tests. The results showed that different cotton, polyester, and spandex fiber compositions did not significantly affect knitted denim fabrics’ weight per unit area, abrasion resistance, and different color fastness properties. However, the elongation and vertical wicking test data showed that the knitted denim fabrics with a higher cotton fiber ratio were better. However, the results from shrinkage, spirality, pilling, recovery, strength, air permeability, and liquid absorbency capacity tests revealed the benefits of having a higher polyester fiber ratio in the cotton/polyester/spandex blended knitted denim fabrics. One-way analysis of the variance test was also performed on the generated data of this study and reported in the respective section of the article.

“…Further increase in punching density also caused the number of fibers in unbounded region to decrease and the thickness of unbounded region to be thinner. Hence, unbounded regions got weaker for abrasion action with the effect of further increase in punching density [18]. As a result, that needling level and depth of penetration should be also best fit with the required weight of car carpet, because excessive needling may also weaken the nonwoven fabric.…”

“…While stiffness was improved in the study, abrasion resistance of fabric samples was not affected significantly in the given range of needle punch density (75–125 punches/cm 2 ) and depth of penetration (8–12 mm). Koç and Çinçik [18] investigated two process variables (fabric mass per unit area and needling density) on abrasion resistance of needle-punched nonwovens made of polyester and viscose blends. They observed that the higher the fabric mass per unit area, the better was the abrasion resistance achieved.…”

In this study, velour design molded automotive carpets made of recycled polyethylene terephthalate (PET) fibers were developed via needle-punching process to improve their abrasion resistance properties. Initially, virgin PET fibers and recycled PET (rPET) fibers derived from PET bottle wastes were supplied from different producers and they were tested in terms of their fiber properties such as fiber length, crimp, tensile strength, elongation, tenacity, and intrinsic viscosity. It was demonstrated that recycled fibers from bottle wastes used in the study have lower tenacity and higher elongation than virgin PET fibers. In the second part, rPET fibers to be used in manufacturing in terms of their desired properties were selected. Subsequently, molded automotive carpets were produced from the selected rPET fibers and virgin PET fiber blends with adjusted manufacturing and molding parameters. Developed carpets were tested for abrasion resistance performance and they were evaluated according to requested specification. Results showed that carpets made of 85% rPET + 15% bicomponent PET had almost equal performance in terms of both fiber loss and carpet appearances with carpets consisting of 80% PET + 20% bicomponent PET. Carpets made of recycled PET fibers offer the manufacturer low raw material costs in addition to ecological advantages.
