Abstract

A research object in work is a technological process of production of electroinsulating fiber glass fabric 771 (90) at facilities of OAO ―Polotsk-Steklovolokno‖. Fiber glass fabric of brand 771 (90) is designed for production of flexible isolation. Fabric 771 (90) is produced on the Jat 710 pneumatic machine with the high level of deficiency – 2.51 defects per 100 meters. Nine types of electroinsulating fabric 771 (90) are produced with various warp threads filling tensions and rotation frequencies of the machine‘s main shaft. It is determined that decrease of warp threads tension 637 to 578 N allows to reduce the deficiency level of fiber glass fabric 771 (90) from 2.51 to 1.63 defects per 100 m of fabric, i.e. by 34.2%. At the same time it is possible to increase the rotation frequency of the machine‘s main shaft from 650 min-1 to 700 min-1.
