Abstract:
In this paper, a kind of radiation resistant knitted fabric with higher elastic response rate was developed. Three kinds of cotton /stainless steel/spandex double filament core-spun yarns and three kinds of cotton /stainless steel core-spun yarns with different linear density were spun by using complete condensed Siro-spinning. In the spinning, the double filament core-spun yarns were spun by feeding the stainless steel and spandex filament into the front roller of spinning machine, and corresponding 1+1 rib loop weaves was knitted. Then, the covering effect and the qualities of six simple yarns, and the elastic recovery rate, electromagnetic shielding properties and fabric styles of six sample fabrics were tested and compared. The test results indicated that all the yarns have good covering effect and good yarn performance. Compared to stainless steel core-spun fabric, the double-core fabric have a better advantages in elastic recovery ratio and shielding electromagnetic waves to meet the requirements of general civil electromagnetic shielding fabric and to guarantee human comfort. The development of flexible electromagnetic shielding fabric not only focus on selection of a reasonable filament pre-draft multiple and other processes, but also take the usability, durability and production costs of the fabric into account.
Key words: double filament core-spun yarn, complete condensed spinning, embedding composite spinning, electromagnetic shiclding, knitted fabric
