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.

Currently, all over countries call for greening the earth. Whereas, there is no enough space to be planted by developing countries, owing to their excessive and intensive development. For establishing green globe, every country expects to green forming urban forest in the way of soilless culture, attached with far-infrared fiber in order to promote root growing speed. This study uses polyester (PET) fiber and far-infrared PET (FIR) fiber to form PET/FIR composite nonwoven fabric by nonwoven processing technology. In this process, blending ratio of PET and FIR fibers was varied. Afterwards, moisture retention, air permeability and far-infrared emissivity of PET/FIR composite nonwoven fabric were all tested. The results show that, blending ratio of PET and FIR fibers has no significant influence on moisture retention and air permeability, but obviously impacts on far-infrared emissivity.

Spunlaced nonwoven fabrics have been widely used recently, but fundamental research on the spunlaced nonwoven process is relatively weak. It is inexplicit until now how fibers are entangled with each other during the hydroentangling process. In this paper, a pull-out experiment designed to study the entanglement properties of spunlaced nonwoven fabrics using common and hydrophilic PET fibers as objects is described. It was found that the broken fiber content can be used to represent the entanglement intensity of the spunlaced nonwoven fabrics. In addition, a formula was set up to calculate the tensile strength of the spunlaced nonwoven fabric based on its pull-out behavior.

In this research, biodegradation behaviour of nonwoven fabrics suitable for wet wipes having different fibre types such as regenerated cellulose (viscose and Tencel), polyethylene terephthalate (PET) and their blends were investigated. Each nonwoven fabric was buried in soil and test samples were controlled in regular periods. Visual appearance was reported and examined by photographs and microscopic views. According to the changes in visual appearance and weight loss, biodegradation was examined in a systematic way. It has been observed that regenerated cellulose nonwoven fabrics and the PET nonwoven fabrics show big difference under the same degradation conditions. PET fibre content delays biodegradation in the soil and degradation behaviour is similar the content of PET fibre in fabric structure. The higher PET, lower degradation, and the higher cellulosic fibre, the higher degradation was determined for nonwoven fabrics suitable for wet wipes.

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.

Nanofibers have high cell affinity due to their fine structure and surface roughness, and are expected to be used as biomaterials. In particular, magnetic nanofibers containing magnetic particles are expected to be used for magnetically induced drug delivery systems and hyperthermia. However, due to the aggregation of the magnetic particles contained in the nanofibers, there is a problem that the aggregation location becomes a starting point of fracture and causes a decrease in tensile strength. In this study, to improve the dispersibility of magnetic particles in Magnetite/PLA nanofiber nonwoven fabrics for suppressing the decrease in tensile strength, magnetite is subjected to surface treatment with oleic acid or stearic acid and ultrasonic agitation. Magnetite/PLA nanofiber nonwoven fabric was prepared by the electrospinning method, and dispersion of magnetite in PLA nanofiber nonwoven fabric and tensile strength were evaluated. Magnetite dispersion was improved by the surface treatment and increasing the ultrasonic agitation time. In particular, by performing the stearic acid treatment and prolonging the ultrasonic agitation time, the magnetite dispersion tended to be improved. This treated Magnetite/PLA nanofiber nonwoven fabric showed higher tensile strength.

This study produces the far-infrared emitting composites by using impact-resistant polypropylene, short glass fibers, and far-infrared masterbatches. The addition of short glass fiber and far-infrared masterbatches is then evaluated to determine their influence on the mechanical properties and far-infrared emissivity of the resulting composites. The experimental results show that with an increase in the content of short glass fibers, the tensile strength increases from 34 MPa to 56 MPa, the far-infrared emissivity increases from 0.85 to 0.93, but the impact strength decreases from 1037 J/m to 197 J/m, proving that the resulting composites have desired mechanical properties and far-infrared emission.

Insufficient endothelialization of stent grafts tends to cause a problem of thrombosis formation. Because the structure of nanofibers, generally defined as fibers with a diameter below 1 μm, resembles the structure of an extracellular matrix, nanofibers are applied to scaffolds for regenerative medicine. Using nanofibers as the covering material of the stent graft can be expected to solve the problem of the stent graft. Previous studies have shown that a porous scaffold offers better surfaces to anchor and culture endothelial cells than a nonporous scaffold. Therefore, fibers with nanoorder dimples are expected to promote endothelialization. As a method of forming the dimple shape on the surface of the PET fiber, there is a method utilizing a difference in the volatilization rate of the solvent in the high humidity environment in the electrospinning method. For practical application of the stent graft to artificial blood vessels, the mechanical properties of the dimpled PET fiber should be clarified. In this study, the mechanical properties of single nanofibers and nonwoven fabrics of PET fibers with dimples on their surface were evaluated by tensile test. By forming the dimple shape on the fiber surface, the tensile strength of single PET fibers with dimples was 90 % lower than that of single PET fibers with a smooth surface. In the fabrication process of nonwoven fabric, the addition of EG delayed the volatilization of the PET solution, and the fibers adhered to each other. The bonding between the fibers contributed to the tensile strength of the nonwoven fabric.
