In this research, we create a PET/TPU/PU composite base fabric from a PET nonwoven base fabric, a TPU honeycomb grid, and a PU foam plank. First, the PET base fabric is made from 7D three-dimensional-hollow-crimp fiber (7D PET) and low-melting-point (low-Tm) fibers with weight ratio and number of lamination layers as the parameters. The hardness and rebound resilience rate of the PET nonwoven base fabric are 71% and 63.5%, respectively. The PET nonwoven base fabric's optimum air permeability is 240 cm3/s/cm2. The maximum tensile strength of the PET nonwoven base fabric with 9 layers of lamination is 39.8 kg/cm2, and when the weight ratio is either 4:6 or 3:7, changes to 40 kg/cm2. The PET/TPU/PU composite base fabric has a LOI of 33 when the number of lamination layers is 10, or when the low-Tm fiber content is 50%; the composite base fabric's average optimum thermal conductivity is 0.914 W/mK.

Pet Fibers

Five testing matrixes were prepared to test with sound absorption, tensile strength, and thermal conductivity respectively. The low-melting-point (low-Tm) polyester (PET) fibers were blended with weight ratios (10 wt%, 20 wt%, 30 wt%, 40 wt% and 50 wt %) with PET staples, forming the PET nonwoven fabrics. The thermoplastic polyurethane (TPU) was thermal bounded with the nonwoven fabrics with different lamination number to examine the sound absorption rate, creating the PET/ TPU composites. Afterward, four sets of samples – PET nonwoven fabrics and PET/ TPU composites with TPU films laminated on the front, in the middle, and on the rear of the composites, were compared. PET/ TPU composite with TPU film laminated in the middle exhibited the optimum sound absorption; moreover, 30 wt% was proved to be the optimum parameter of the low-Tm PET fibers for the PET/ TPU composites.

Heat energy plays a significant role in resources and industries, which makes the development of energy-saving and thermal retention materials important to environment protection. This study combines three-dimensional hollow Polyethylene Terephthalate (TPET) fibers, recycled far-infrared polyethylene terephthalate (RFPET) fibers, and low melting temperature polyethylene terephthalate (LPET) fibers at various ratios to make the RFPET/TPET hybrid nonwoven fabric. The tensile strength, tearing strength, air permeability, and far infrared emissivity of the fabrics are evaluated. With a blending ratio of 8:0:2, the hybrid nonwoven fabrics have the optimum tensile strength of 145 N, tear strength of 184 N, and air permeability of 205 cm3/cm2/s.

Polymeric Waste

Polymeric material, which is commonly used in packaging, has been widely applied due to the fact that it is lightweight and chemical resistant. Being non-degradable, polymeric waste can thus only be eliminated by burning, and subsequently, there is a rising need for degradable polymeric material to manage this manner of disposal. This study thus uses degradable, low-melting-point polylactide (LMPLA) fibers and recycled polyester (RPET) fibers to make nonwoven fabrics for packaging. The tensile strength, tear strength, and air permeability of the nonwoven fabrics are then tested. The experiment results show that a 40% of RPET fibers can effectively promote the mechanical properties of the LMPLA nonwoven fabrics.

Absorbing Property

In recent years, as quality life improves, people begin to focus on quiet environment. Long-term noise pollution makes trouble of dysphoria and concentrating for people, thus noise-reduction has become an urgent project. This study uses Nylon 6 fibers, blended with different contents of low-melting PET fibers (10 wt%, 20 wt%, 30 wt%, 40 wt% and 50 wt%), to fabricate Nylon6/ LPET nonwoven fabrics after needle-punching process. Afterwards, their maximum tensile strength, air permeability, sound absorption coefficient were all evaluated. When low-melting PET fibers contain 30 wt%, the nonwoven fabric has the better sound-absorbing property. Herein, the maximum tensile strength reaches 70.79 N and 31.01 N, respectively in CD and MD; the air permeability is about 116.5 [cm3/(cm2/s)]

Electromagnetic Shielding Effectiveness

Conductive textiles can be used in diverse fields, such as antistatic materials, sensors, materials for electromagnetic shielding and biomedical. This study produces nonwoven fabrics with polylactic acid (PLA) and polyaniline (PAN) and the resulting PLA/PAN nonwoven fabrics are evaluated with electromagnetic shielding effectiveness (EMSE) and air permeability. Polylactic acid (PLA) and low melting point polylactic acid (LPLA) are made into nonwoven fabrics, which are then spray-coated with different amount of PAN solution to form PLA/PAN nonwoven fabrics. The fabrics are laminated with various numbers of layers, and then thermally pressed. The experiment results show that the PAN amount and lamination number are proportional to the EMSE of the PLA/PAN nonwoven fabrics.

As social civilization advances, more and more people reside in the city. Consequently, the number of automobiles and locomotives increases, causing greenhouse effect and noise pollution increasingly serious. Therefore, lowering the temperature and reducing the noise in living conditions has become an urgent task, in order to save resources usage amount and to produce a low-noise dwelling environment. In this study, the sound-absorption and heat-insulation nonwoven fabrics were firstly prepared by three-dimensional crimp hollow polyester fiber (PET) fibers and Polypropylene (PP) fibers based on nonwoven processing technology, following by sound-absorption coefficient test, thermal conductivity test, as well as maximum tensile strength and maximum tearing strength tests. The results show that, 70/30 wt% PET/ PP nonwoven fabrics have the maximum tensile strength of 2.47 MPa (CD) and 1.67 MPa (MD), in addition with the maximum tearing strength of 83.96 kN/m (CD), 111.88 kN/m (MD); the 90/10 wt% PET/ PP nonwoven presents the lowest thermal conductivity coefficient of 0.0365 W/K‧m; nonwoven with three different ratios show the similar sound-absorbing curves, which all reaches the highest absorption coefficient of 0.76 at 4000 Hz.

Pu Foams

In this study, two agents (a foaming agent and a hardener) are mixed to form rigid polyurethane (PU) foams with various densities, which are separately poured into a mold with a three-dimensional (3D) fabric to form 3D fabric/foam composites. The mechanical property and sound absorbency of the composites are examined. The experiment results show that an increasing density of the two-agent mixture results in a more compact PU foam, a 31 % increase in bursting strength, and a greater resilience, but also a decrease in the sound absorbency coefficient. In sum, variations in the density of the mixture have an impact on the physical properties of the fabric/foam composites, the derived results of which can thus be further applied to product designs.
