Elastic cloth is popular in the market. Customers who buy jeans need to see if there is elasticity. Elastic cloth is favored by the majority of users because of its flexibility. However, elastic cloth will slip when sewing. If you don't master the method well, there will be jumping in the sewing process. Therefore, by adding a pneumatic telescopic brace, the elastic material is stretched to a state that is not easy to slip, and the material is assisted by the rear tugboat device. Because the whole machine is cylindrical, it is convenient for the operator to directly insert the elastic material and sew it together, which improves the overall efficiency.

Whether LEDs have blue light damage has been controversial. To clarify the truth and give LEDs a name, DOE has issued a report on LED lighting and blue light hazard. Recently, DOE once again stated its position in the technology report TrueColors. The DOE said in the report that it is well known that excessive exposure to blue light (wavelengths of about 400-480 nm) causes retinal damage, while white LEDs typically emit peaks at around 450 nm. But this does not mean that LEDs can cause vision damage, physical and physical damage more than other traditional light sources. In fact, in the same color temperature (CCT), the blue light contained in the LED is the same as that of the conventional light source, and the energy consumption of the LED is less than that of the conventional light source above and below 450 nm. Therefore, the harmfulness of the LED to human health is Other light sources should be small. In addition, DOE pointed out that local museums have begun to adopt LED lighting, which is the most favorable proof that LED does not harm the goods. CREE hybrid LED and OLED white light technology won the US patent Recently, a US patented CREE's invention patent hybrid LED and OLED white light technology was approved by the US Patent and Trademark Office, patent number is US8841834B2. CREE said that this new The invention combines LED illumination with OLED illumination to form a white light solid state illumination system. The LED and the OLED are placed in the mixing chamber of the luminaire at a certain interval, and the blue-yellow light emitted by the LED is combined with the red light emitted by the OLED to generate white light, and the color rendering index is as high as 90.
