Recycling of textile waste into green composites: Performance characterization

Abstract

Recycling of any waste is as such a worldwide phenomenon. In this context application of textile waste for development of some value added product has been thought of in this work. Textile fabric waste is collected from various sources. These waste materials are garneted, so as to produce loose fibrous material. Subsequently this fibrous material was converted into nonwoven web and also twisted strand for manufacturing of 3D woven preforms to be used in composites. In case of nonwoven preforms, the webs are produced by combining polypropylene with cotton component with different proportions. Composites of various specifications are developed to examine their application in several end uses. These composite materials are characterized for their mechanical and thermal behavior in order to find out the response against tensile loading, impact force and thermal loading. The effects of moisture absorption on mechanical properties of these composites are investigated. As the percentage of PP fibres is increased in the web, mechanical performance of the composite material is improved in general. The exposure of composite material to high humidity condition has not shown any significant change in their mechanical behavior. 3D woven fabric reinforced composite produced by using garneted fibre yarn and virgin cotton OE yarn didn't exhibit any significant difference in the mechanical and thermal behavior of composite. The results confirmed that textile waste material can be safely used as reinforcing structure in composite manufacturing. POLYM. COMPOS., 35:1960–1967, 2014. © 2014 Society of Plastics Engineers

Thermal and mechanical characterization of novel basalt woven hybrid structures

“…The tensile testing speed was kept at 100 mm/min. This test was performed according to standard EN ISO 13934-1 (Mishra, Behera, & Militky, 2014). The specimen size for tensile testing was 20 cm × 5 cm as per standard.…”

Environmental Implications of Recycling and Recycled Products

“…Subsequently, this fibrous material was converted into a nonwoven fibrous mat and also twisted for making yarn to be used in manufacturing 3D woven preforms for use in composites (Mishra et al 2014). Textile fabric waste was collected from various sources and these waste materials were garneted, so as to produce loose fibrous material.…”

Flame retarded polyethylene/wood flour composites with high performances: Satisfying both sides with intumescent flame retardants and synergistic compatibilizers, respectively

“…Wood plastics composite (WPC) is one of the popular eco composites that are manufactured by combining natural fibers and polymers [1][2][3][4]. It has gradually gained popularity in commercial markets for construction and automobile [5,6].…”

“…Some commercial products require V0 classification in the UL94 flame testing and selfextinguish properties in the vertical burring testing is required to satisfy V0 classification [9]. V0 classification should meet the following requirements (1) The specimens may not burn with flaming combustion for more than 10 s after either application of the test flame; (2) The total flaming combustion time may not exceed 50 s for the 10 flame applications for each set of 5 specimens;…”
