The quality of the silk is selected to fundamentally determine the quality of the silk quilt. Different quality silk can be correctly identified from the following five aspects:
Exterior
High-quality silk has a pearl-like appearance and diffuse refractive properties. There are few impurities in the cleanliness, and the silk roads are orderly and orderly; while the poor quality silks are often bleached and add other chemicals such as bleaching agents, leaving them with a pale appearance, a lack of luster and moisturizing, a lot of impurities, and messy silk paths.
Tactile
High-quality silk feels smooth, creamy and elastic, and there is no rigid mass; while inferior silk has rough touch, no flexibility, no moist feeling, and there are relatively more pods, lumps, scorpions, and pods.
taste
Silk with oily or musty odors are all inferior products.
combustion
Silk does not have flammability when burned, and it ceases to ignite when separated from the flame. It is loose ash after burning and has a burning smell of hair.
Fiber strength
The better the silk strength, the better the quality. Studies have shown that the strength and strength of super-sized mulberry silk should be stronger than that of iron wire of the same diameter. High quality silk and excellent recovery elasticity; poor silk strength, elastic recovery and other fiber properties are poor.
