Where is personal tailor silk quilt in Chengdu?

Sichuan is a big silk-producing province, and many large regular silk reeling factories are producing pure high-grade silk quilts with 100% high-quality mulberry silk.

As for private production, I suspect that the spinning degumming process of cocoon is not well controlled. This is not a manual technical problem, but involves the chemical process of reeling. If degumming is not complete, it will not only cost money to buy useless sericin, but also sweat will evaporate after covering for a long time, which will cause sericin to become sticky and finally reduce its bulkiness.
