Lun fiber (fire fighter clothing)into yarn in the process of unwinding twist severe impact of the use of the following process, we chose the yarn steaming process to solve this problem. Yarn steaming equipment used the most advanced Xorella steamer in the world today, the Model LT-O; Dimensions 2000 × 4000; electric heating; Control Type: OP270.
Yarn steaming equipment function mainly: Spool air through the vacuum device emptying; gaseous cold saturated steam to penetrate to the yarn guide; alternate the airflow through the vacuum and cold saturated steam balanced across the spool; cold vapor homogeneous moisture distribution in the bobbin, yarn absorption. This will produce the same intensity of friction value, spiral through the heat treatment(fire boots) to eliminate stress.
Treatment process using indirect steam technology, and set in the processing chamber vacuum environment, run precisely along the saturated vapor curve This prevents impact of the items being processed, no to concentrate traces and to ensure a uniform high quality. Completely clean the indirect import saturated steam, and in the gaseous state, has the best ability to penetrate. Even outside the Grand Cross of the spool on the reel core and core, and also subjected to the same steam treatment. Since the winding, weaving, bending or weaving workshop process flow is improved, so as to obtain uniform yarn quality and improve customer satisfaction. 50 ~ 150 ℃ saturated steam may be in the processing chamber to generate a vacuum. Vacuum to absorb residual air and support the process of penetration of the items being processed. This thermal shock can be prevented and by gentle steam treatment, relaxation and humidity-off yarn.
