Plastics have prominent utilization worldwide. Polyethylene Terephthalate (PET) is one of the major types of plastics that can be found in the Municipal Solid Waste (MSW) [1]. MSW contains high proportion of thermoplastic polymers which has been increasing in value. PET is a semi-crystalline thermoplastic polymer, and is considered as polyester material [2]. Large amount of waste PET is being p...

This paper presents the influence of Hybrane H 1500 as a hyperbranched polymer on kinetic parameters of dyeing compounded fiber grade PET polyethylene terephthalate at boil temperature. C.I. Disperse Red 324 as a disperse dye was used for dyeing compounded fiber grade PET. The result was compared with corresponding properties of virgin PET. The dyeing rate constants and diffusion coefficients a...

low temperature plasma technology is well established in surface modification of polymer materials on industrial scale. this method modifies surface properties of polymers without chemicals, manual work and reducing chemicals and energy consumption. in this study, low pressure plasma treatment was used to develop hydrophilic properties of polyethylene terephthalate (pet) fabrics. it was found t...

Slow multiply charged ions are efficiently guided through nano-capillaries with large aspect ratio in polyethylene terephthalate (PET), due to self-organized charging of the inner capillary walls which prevents close collisions with the surface. In order to gain more insight into this interesting phenomenon we have measured the 2-D scattering distribution of transmitted ions during the charge-u...

Dyeing properties of compounded polyethylene terephthalate fibers with a polyesteramide hyperbranched polymer were investigated in terms of their thermodynamic parameters, including standard affinity -Δμ⁰, enthalpy change ΔH⁰ and entropy change ΔS⁰. Results were then compared with corresponding properties of the virgin PET. The results showed that the isotherms were similar to that of virgin PE...

Porous pigments in which chemically responsive dyes have been immobilized in a matrix of organically modified siloxanes (ormosils) have been prepared and characterized by AFM, TEM, EDS, and optical analysis. In typical chemical sensing applications, an array of 36 different porous ormosil pigments are deposited on polyethylene terephthalate (PET) film.

Polyethylene terephthalate LARS ligament were the remnant of LARS ligament used for repairing posterior cruciate ligament obtained from operation. We want to study histological characteristics and ultrastructure of polyethylene terephthalate LARS ligament after the reconstruction of anterior cruciate ligament in rabbits. Therefore, we replaced the original ACL with polyethylene terephthalate LA...

Industrial-scale upcycling of waste polyethylene terephthalate (PET) plastic into porous carbon globally for CO 2 capture was verified as a multifunctional alternative to conventional absorption and management technologies.

The glycolysis of postconsumer polyethylene terephthalate (PET) waste was evaluated with catalysts of zinc acetate, zinc stearate and zinc sulfate, showing that zinc acetate was the most soluble and effective. The chemical recycling by solvolysis of polylactic acid (PLA) and PET waste in either methanol or ethanol was investigated. Zinc acetate as a catalyst was found to be necessary to yield a...
