Development of stainless steel fiber /cotton composite yarn and its performances

In order to better develop functional yarns and fabrics,a kind of novel composite yarn made of stainless steel filaments,stainless steel short fiber and cotton was introduced. A novel filament /short fiber composite spinning technology was employed to develop composite yarns with different contents of stainless steel fiber. The inside structures,hairiness index,tensile and conductive properties of the composite yarns were tested,along with the electromagnetic shielding effectiveness of fabrics made of these composite yarns. Results showed that the composite yarns exhibited small hairiness index,good tensile and conducting properties. Stainless steel fiber contents had remarkable influences on these performances. Percentage of electromagnetic shielding of the fabric made of these composite yarns reached 90. 0%- 99. 9% which meets the requirements of electromagnetic shielding materials.
