Tire Abrasion as a Major Source of Microplastics in the Environment

open access: yes, 2018
Traffic-related non-exhaust particulate matter mainly consists of tire wear, brake wear, and road wear. For this study, passive-samplers were placed near highly frequented roads in industrial, agricultural, and urban environments with the aim of ...

Testing of yarn abrasion [PDF]

open access: yesAutex Research Journal, 2013
Abstract There exist a lot of methodologies, which can be used for yarn quality testing. Abrasion resistance and its measurement for raw and sized yarn can help in the judgment of yarn weaving-ability. This article concentrates on the possibility of yarn abrasion expression and testing.
