1, the sour silk quilt is slightly sour because it has been degummed during production, which is an important link in silk processing. The national standard stipulates that the PH value of silk quilt is between 4 and 7.5, so if it is very acidic, it does not meet the national standard of silk quilt. Degumming makes sericin of silk fall off, making silk softer and warmer, and wrapping silk fibroin is easier to contact with human body, so that human body can better absorb various amino acids and achieve the effect of beauty and eye protection. In addition, the degummed silk quilt can be washed without turning, which is a relatively high-grade process.
2, the taste of silkworm, the main filler of silk quilt is silk, whether it is mulberry silk or tussah silk, there is a kind of fragrance of silk itself, but if this fragrance is particularly strong, it still can't be scattered after drying, you should consider whether silk is made up of inferior cocoons such as "oil cocoons, cocoons, cocoons, rotten cocoons".
Matters needing attention in purchasing silk
1. Look at the purity: 100% high-quality mulberry silk is used as raw material, the silk quilt with the unique smell of silkworm chrysalis is the top grade, and the silk with oily or musty smell is the bottom grade.
2, look at the craft: handmade is better. The four corners or sides of the quilt cover should be provided with sample observation ports so that consumers can check the quality of the silk inside the quilt cover; No mechanical quilting can ensure the softness and breathability of silk quilt.
3, look at the quality of silk: high-quality silk should be milky white, the surface has a uniform natural luster is better, it is not appropriate to choose bleached silk, dark or strange luster silk quilt; Silk should be long and elastic. The stronger the silk, the better its ductility and quality. The longer the silk with the same length is stretched, the better the quality. If cotton wool, impurities and other chemical fibers or silk roads are found in silk, and fluorescence reflection is found, please do not buy them.
