<b>Title: Spun yarn from staple fibres</b>
The invention relates to a spun yarn made from staple fibres, which yarn consists of a single strand comprising at least 30 mass% of staple fibres that have been obtained from a precursor continuous multifilament yarn having a tensile strength of at least 16 cN/dtex; a tensile modulus of at least 700 cN/dtex; and a denier per filament of fibre of at most 18 dpf; which staple fibres have an average fibre length of between 40 and 180 mm; and essentially no crimp; and which spun yarn has a twist level characterised by an α twist coefficent (Koechlin law) of 60 -100 t. m -1 .(m/g) -1/2.
The invention further relates to a process for making said single-strand spun yarn, to the use of said spun yarn for making various semi-finished and end-use products, and to such products comprising the spun yarn.
