Abstract

The invention discloses a method for improving the unwinding ratio of silk, and belongs to the technical field of silk processing. The method comprises the following steps: preparing a silk unwinding agent, penetrating, boiling cocoons, rinsing, regulating silks, spinning, and reeling. The method is scientific and feasible, the operation is feasible, the sericin in the inner layer of cocoons is fully swelled, the temperatures of cocoon boiling and silk regulation are reduced, the inner layer can be cooked, while the dissolution of sericin in the outer layer is inhibited; the cocoon boiling is optimized according to the physical and chemical properties of silk, after the cocoons are processed by the provided method, the silk unwinding ratio can reach 79.6 to 81.2%; the unwinding ratio is improved by 6.2 to 8%; the broken rate of silk during reeling process is reduced by 5.3 to 7.6%, the silk cleanness score reaches 95 to 95.8, and the cleanness score is improved by 2.12 to 2.85.

Description

technical field [0001] The invention belongs to the technical field of silk processing, in particular to a method for improving the unwinding rate of silk. Background technique [0002] Silk is obtained by spinning silk, and silk is processed by reeling and cooking cocoons. The process of silk reeling and cooking mainly includes cocoon mixing, cocoon stripping, cocoon selection, cocoon cooking, silk reeling, re-shake, finishing and other processes. Among them, the cocoon cooking process uses the action of water, heat or chemical additives to make the cocoon silk glue properly swell and soften, reduce the adhesive force between the cocoon silks, and make the cocoon silks dissociate in sequence to meet the requirements of reeling. silk production requirements. Different cocoon cooking techniques and technical measures are used in silk reeling production, which has a great impact on the quality of silk reeling. Only when the cocoons are boiled can the silk be reeled well, esp...
