Abstract: In this paper, a kind of novel composite yarn made of stainless steel filaments, stainless steel short fiber and cotton was introduced. Composite yarns were developed by a novel filament/short fiber composite spinning technology. Structures, hairiness index, tensile properties and conductive properties of yarns with different stainless steel fiber contents were tested. Electromagnetic shielding effectiveness of fabrics made of these composite yarns were also discussed. Results showed that the composite yarns exhibited good performances, and stainless steel fiber contents had remarkable influences on these performances. Percentage of electromagnetic shielding of fabric reached up to 90%~99.9% which meets requirement of daily life.

Key words: stainless steel fiber, cotton, spinning technology, composite yarn, electromagnetic shielding
