At present, bedding on the market, everyone is clearly marked in the number of places, in fact, the number of yarn count is a more popular international saying, the domestic generally said how much density.
The main difference in bedding prices is not just how many yarn counts (just one of the most important factors). Of course, the price is mainly on the fabric.
Generally speaking, printing means that after the cloth is woven, the pattern is printed again, and there are active printing and general printing. The price of 30S printed bedding is about 100-250 yuan, and the good is also more than 400 yuan (refers to other index factors, such as yarn count, twill, cotton content, etc.).
Embroidery means that after the cloth is woven, the pattern is embroidered by the machine (generally). Compared with the printing, it does not fade when washed. The breathable moisture absorption is good. The price is generally above 400 yuan.
Jacquard is a pattern on the fabric that is woven with different colors of yarn when weaving. Compared with embroidered fabrics, the cost is higher, the quality and the air permeability are better. Therefore, the price is above 800 yuan.
When buying bedding products, especially high-end bedding products, do not blindly pursue high yarn counts. See what fabrics (in the end, printing, embroidering, or jacquard) is the dividing line of price.
Precision Optical Flats are ideal for a variety of applications including interferometry, imaging systems, laser applications, optical path folding, and autocollimation. These mirrors are available in a variety of coating and substrate options, along with surface flatness options of λ/10 and λ/20. Fused Silica, is optically clear and features excellent resistance to abrasion and high durability, making it the best choice for applications in harsh environments.
Silicon features a Knoop Hardness of 1150 and low density, making it tougher than germanium substrates and suitable for weight-sensitive applications, respectively. Diamond-Like Carbon (DLC) Coated Silicon Windows are engineered for 3 to 5µm, making them ideal for infrared defense applications such as thermal imaging.
Diamond-Like Carbon (DLC) Coated Silicon Windows provide anti-reflection coating on one surface and a specially designed DLC coating on the other surface, making these windows highly durable and ideal for harsh environments.
