Abstract:

Two recombinant cutinases, AfCutA and AfCutB, derived from Aspergillus fumigatus, were heterologously expressed in Pichia pastoris and systematically characterized for their biochemical properties and polyester-degrading capabilities. AfCutA demonstrated superior catalytic performance compared with AfCutB, displaying higher optimal pH (8.0–9.0 vs. 7.0–8.0), higher optimal temperature (60 °C vs. 50 °C), and greater thermostability. AfCutA exhibited increased hydrolytic activity toward p-nitrophenyl esters (C4–C16) and synthetic polyesters. Additionally, AfCutA released approximately 3.2-fold mo

Abstract:

Polyurethanes (PU) are one of the most-used classes of synthetic polymers in Europe, having a considerable impact on the plastic waste management in the European Union. Therefore, they represent a major challenge for the recycling industry, which requires environmentally friendly strategies to be able to re-utilize their monomers without applying hazardous and polluting substances in the process. In this work, enzymatic hydrolysis of a polyurethane-polyester (PU-PE) copolymer using Humicola insolens cutinase (HiC) has been investigated in order to achieve decomposition at milder conditions and

This work first synthesized a series of linear polyesters by step-growth polycondensation, then an amino-terminated hydrophilic polyether was grafted to the polyester as side-chains through aza-Michael addition to prepare a self-dispersible, non-ionic waterborne comb-like polyester (NWCPE). In contrast to traditional functionalization methods that usually require harsh reaction conditions and complex catalysts, the aza-Michael addition proceeds efficiently at room temperature without a catalyst. In this facile and mild way, the NWCPE samples with number-average molecular weight (Mn) of about 8

The weight loss of polyester fabric was found to be greatly dependent on the concentrations of ILs and the length of alkyl groups in ILs. C14MImBr and C16MImBr exhibited good catalytic actions.

A key challenge in textile recycling is blended yarns, such as polycotton blends, which consist of polyester and cotton.

High crystallinity leads to low hydrophilicity of fabric made of (poly(ethylene terephthalate)) fibers (PET) causing problems in finishing, washing, and dyeing processes.

However, the use of strong alkali and high processing temperatures (>100 °C) can lead to fabric damage and a negative impact on the environment.

Increasing environmental awareness has highlighted the importance of plastic recycling and rightfully so, considering plastic pollution and an ever-increasing consumption of plastic products. Currently, numerous recycling strategies are being investigated with varying approaches depending on the type of polymer [1]. One attractive process is the chemical recycling of polyesters via alkaline hydrolysis which produces the dicarboxylic acid salts and diols of the respective polyester. The dicarboxylic acids can be separated by crystallization, while the diol separation remains a challenge. A proc

Abstract:

Currently in Malaysia, most wastes are disposed into poorly managed systems with little or no pollution protection measures. Large amounts of wastes such as textiles are generated through hospitals and health care centers. However, the improper management of these abundantly generated wastes may pose an environmental pollution problems and fire hazard. Cotton textile is a potential biomass for bioethanol production. Subcritical water (Sub-CW) hydrolysis was investigated as an alternative technology for the recycling of cotton textile waste for current health care waste management. The aim of t

Abstract:

A new circular economy concept is presented for the textile sector to convert unwearable polyester textile waste into valuable chemical feedstock. The idea behind it is to develop a new circular economy concept for the most used material in the textile industry, that is, polyester. Hydrothermal hydrolysis, an environmentally friendly process, has been studied for recovering polyester monomeric units. Under high-temperature and high-pressure conditions complete chemical depolymerization of pure poly(ethylene terephthalate) (PET) to terephthalic acid (TPA) was achieved at high yield. The produce

Abstract:

Aliphatic and aromatic polyesters of hydroxycarboxylic acids are characterized not only by biodegradability, but also by biocompatibility and inertness, which makes them suitable for use in different applications. Polyesters with high enzymatic hydrolysis capacity include poly(lactic acid), poly(ε-caprolactone), poly(butylene succinate) and poly(butylene adipate-co-terephthalate), poly(butylene succinate-co-adipate). At the same time, poly(lactic acid) is the most durable, widespread, and cheap polyester from this series. However, it has a number of drawbacks, such as high brittleness, narrow

Abstract:

Abstract The adhesion of polyester tire cord to rubber decreases during service when it is used in large tires. This phenomenon is recognized as the result of hydrolysis of the polyester by the amine compounds contained in rubber. The carboxylated latex based on the conventional vinylpyridine-butadiene-styrene latex was found to have the function of improving both the adhesion and the cord strength. For further improvement, a latex having more functional groups possessing a function of penetration prevention of amines was found to be effective when it is used in a double layer adhesive system.

The objective of this study was to impart the electrical conductivity to the polyester fabric by applying polypyrrole having a good atmospheric stability, and to fabricate the superhydrophobic surface by using perfluorodecyltriethoxysilane to increase the durability and practicality of electrically conductive fabric. Nanoscale roughness that is essential for superhydrophobicity was given to polyester fabric by the alkaline hydrolysis. Samples simultaneously subjected to surface hydrophobization and the treatment for electrical conductivity exhibited the excellent electrical conductivity (0.55

Abstract:

Aliphatic polyesters, such as polylactic acid (PLA), polyglycolic acid (PGA), polycaprolactone (PCL), polydioxone (PDO) and others, have been commonly used in biodegradable products. Hydrolytic and/or enzymatic chain cleavage of these materials leads to α-hydroxyacids, which, in most cases, are ultimately assimilated in human body or in a composting environment. However, each of these has some shortcomings, in terms of mechanical properties and degradation time, which restrict its applications. The combination of these materials, by copolymerization or blending, enables a range of mechanical p
