Precisely controllable technical problems in the silk thread in silk

Recently, after one year of public beta, Qianhuang Silk 's patented technology "Controlling Silk Mulch Degumming Rate System" successfully applied for national patents. This provides strong technical support for Qianhuang Silk's products to retain more sericin and achieve healthier silk quilts and bedding. Qianhuang Silk, which has 23 national patents, has taken the scientific research and development strength to a new level.

Silk gum is a protein that constitutes the outer layer of silk fiber. It is rich in 18 kinds of amino acids, and more than 90% can be absorbed by the human body. It is called "vitamin" in silk. There are many long-chain amino acids and polar hydrophilic groups on the sericin chain. These structural features give the sericin excellent moisturizing, moisturizing and anti-oxidation effects, which can effectively moisturize the skin and relieve dry and wrinkled skin.

Silk gum, known as the "vitamin" in silk

In recent years, as the value of sericin has gradually gained recognition, sericin is widely used in high-end cosmetics, textiles, medicine, jewelry and other fields. In fact, in the early years, sericin was usually used as waste to be discharged with waste water. Nowadays, sericin is generally sold separately in the process of peeling and silking. It has become the main source of silk mask and the most effective component of silk.

Anyone who knows a little about silk knows that the key to its health care performance is sericin. Silk gum is a natural water-soluble protein with active properties. It is easy to be knotted and yellowed under hot and humid conditions, and it is used for the cooperation of silk fibers. Generally, silk is degummed during the production process. However, if the silk gel is removed too much, it will directly affect the performance of the silk; if it is retained too much, in the long-term use process, the evaporation of water and a small amount of salt will be absorbed in the silk. This makes it easy for the quilt to become yellow and needs to be refurbished frequently.

At present, the silk fibroin on the market is quite a concept of "silk gum", but there are few technologies that control the degumming rate of silk. Based on this market gap, Zhang Jianjian, chairman of Qianhuang Silk, and experts from Zhejiang Polytechnic University, focused on solving the problem of controlling the rate of degumming of silk. Using the bio-characteristics of sericin and using cocoons as raw materials, the existing degumming process was repeatedly tested to comprehensively evaluate the effects of solid glue on the properties of silk, such as warmth retention, moisture retention and softness.

After nearly a year of joint efforts, Qianhuang Silk has overcome the technical problem of applying silk and even silk products - controlling the silk degumming rate system and successfully applying for patents. The content of natural silk sericin is about 20%~30%. Qianhuang can precisely control the content of sericin through this patented technology, and tailor the products with different sericin content suitable for these people according to the characteristics of different people's skin. For example, middle-aged and elderly consumers, because their skin is relatively dry, are in a recession stage, so the products they use will increase their sericin content, thus supplementing the sericin needed for their skin care; for example, infants and young people, The skin itself is moist and elastic, so the amount of sericin is appropriately reduced in the products used. Through the patented technology of Qianhuang, the sericin can be uniformly and stably solidified on the silk fiber, which helps to improve the damp heat stability of the silk fibroin, and effectively improves the silk on the basis of ensuring the original excellent performance. The problem of yellowing of the rubber board is to achieve the purpose of improving the utilization rate of silk.

"The silk quilt without sericin is no different from the chemical fiber," said Zhang Jianjian, CEO of Qianhuang Silk. In addition to this patent for controlling sericin, Qianhuang Silk applied for two other patented technologies for silk: a new structure of silkworm silk drawing bow and a combined silk core. Qianhuang Silk is taking the professional attitude and really raising the silk production process to the height of scientific research technology.
