Comparative Analysis of Peat Fibre Properties and Peat Fibre-Based Knits Flammability

A very promising cellulose-based natural fibre that is suitable for use in the textile industry is peat fibre. This fibre is a by-product of peat excavation, purified by separating it from other components. In this study, the morphological, chemical and mechanical properties of peat fibres as well a...
