Before P > a href= "//m.pmae.cn/news/index_c.asp" > Shandong < /a > Lian Yun new Mstar Technology Ltd "Siro compact spun crystal cotton, long staple cotton blended yarn and its spinning technology" was authorized by the State Intellectual Property Office, with a patent number of 201310051569.6.

It is reported that the invention patent is specially designed for solving the natural crystal cotton industrialization spinning.

< /p >

< p > according to the introduction, the crystal < a href= "//m.pmae.cn/news/index_c.asp" > cotton fiber > /a > comes from the fruit of the wild horn melon plant, which is often grown on barren hills, barren slopes, saline alkali and drought resistant, and is green and environment-friendly. It is a renewable, recyclable green plant fiber.

< /p >

< p > > a href= "//m.pmae.cn/news/index_c.asp" > crystal cotton fiber < /a > light and soft, big and middle cavity structure is warm, sound insulation, moisture absorption and humidity is good, and can be antibacterial, moth proof and mildew proof, but in the spinning process, the fiber is easy to float, and the force between the fibers is poor.

< /p >

< p > the patent system of Lian Yun company has solved all kinds of technical and technological problems in the industrialization of crystal cotton. It has provided strong technical support for developing varieties of crystal cotton products with various varieties, styles and high added value.

< p > it is reported that some researchers in the United States are developing a technology of "4D printing", which will enable large 3D printing parts to be assembled automatically according to the preset structure and appearance mode.

The emergence of this technology will likely revolutionized the traditional manufacturing industry in the future, making it easier to make manufacturing under harsh environmental conditions.

< /p >

< p > 4D printing technology involves the application of special materials. These materials change their shape when they perceive motion state, temperature change, or exposure to water, air, gravity field and magnetic field. The fourth dimension refers to the self assembly behavior of materials.

4D printing is essentially the use of composite materials for 3D printing. In this way, one function is added, that is, deformation.

< /p >

< p > the researchers showed the material printed on the composite material through 3D printing technology, which can be pformed into "M-I-T" after touching water.

This property is added to the material body. Researchers use a special Autodesk software to simulate and optimize how and when the material is deformed. For example, we can use this software to design the nano scale self-assembly system, or to design the large scale self-assembly system at the human level.
