A process for extracting the silk extract from silkworm cocoon and silk includes adding the silkworm cocoon and silk to weakly alkaline or neutral soap solution, boiling for degumming, and immersing in solution of acetic acid to obtain high-purity silk extract. Its advantages are no damage to ...
The knowledge of silk making was a secret in China for over 2000 years. Literally, no other country knew about this fabric. Over time, Chinese immigrants brought knowledge of silk production to North Korea, India, and eventually, the rest of the world. Today China and India together producem...

While silk fibroin (SF) obtained from silkworm cocoons is expected to become a next-generation natural polymer, a fabrication method for SF-based artificial nerve conduits (SFCs) has not yet been established. Here, we report a bioresorbable SFC, fabricat
1. The process starts with silkworm eggs Silk is so common in people's daily life After four days, making cocoons is over Finally, the silk threads are made into cloth The price of silk is low and everybody can afford it It takes about 5,500 silkworms to make 2.2 pounds of silk ...
2.1.1. Cotton is one of the best natural fabrics. Cotton is strong, soft, unlikely to cause allergy. It easy to wash and flame retardant. And it is the most popular natural fabric used in making clothing. 2.1.2. The silk is the strongest natural fabric in the world, it is obtained ...
Exploring whether and how mutation of silk protein contributes to subsequent re-allocation of nitrogen, and impacts on the timing of silk gland degradation, is important to understand silk gland biology. Rapid development and wide application of genome editing approach in the silkworm provide us an ...
The process diagram illustrates in four stages about the life cycle of the silkworm and five states about how silk clothes are produced.According to the first diagram,eggs became to silkworm larva need 10 days.At this stage,larva are fed with mulberry leaf than spend 4-6weeks to transform ...
(OH)2. It has long been known that the salts can be dialyzed out of such aqueous salt/fibroin solutions to produce aqueous solutions of fibroin which are similar in some ways to the liquid contents of a silkworm's silk gland. Fibers have been spun from aqueous fibroin solutions of this ...
