Jade, also known as jade jade, jade, jade, Burmese jade, is a kind of jade, the color is emerald green (called Cui) or red and yellow (called ç¿¡). It is a jade-like polycrystalline aggregate formed mainly of jade, omphacite and sodium chromite during the geological process.
Basic Features
(1) Chemical composition: sodium silicate aluminum-NaAI [Si2O6], often containing trace elements such as Ca, Cr, Ni, Mn, Mg, Fe
(2) Mineral composition: mainly jadeite, followed by omphacite, sodium chromite, neon, hornblende, albite and so on.
(3) Crystallization characteristics: monoclinic system, often columnar, fibrous, felt-like compact aggregate, raw material is blocky secondary material is gravel
(4) Hardness: 6.5-7.5
(5) Gloss: glass gloss
(6) Transparency: translucent to opaque
(7) Relative density: 3.30 - 3.36, usually 3.33
(8) Refractive index: 1.65 - 1.67, 1.66 on the refractometer
(9) Color: The color is rich and colorful, among which the green is the top grade, and the color of the jade is colorful. It is a kind of symbol and a place for people to know jade. Although the color of jade is ever-changing, it is colorless, white, gray, red, yellow, blue, green, purple and black. The colors are uneven, and many colors can appear in a jade.
Origin of jade
They are mainly distributed in the mountains of northern Myanmar. In addition to the jadeite produced in Myanmar, the countries producing jade in the world are Guatemala, Japan, the United States, Kazakhstan, Mexico and Colombia. The jadeites of these countries are characterized by few gem-quality materials, mostly for some engraving-grade craftsmanship. At present, more than 95% of the commercial grade jadeite from the market comes from Myanmar, so jade is also known as Burmese jade.
After treatment is a technical treatment method that gives the fabric a color effect, a morphological effect (smooth, suede, stiff, etc.) and a functional effect (watertight, non-ironing, non-sticking, flame resistant, etc.). The process of improving the appearance and feel of the fabric by chemical or physical main methods, improving the wearing performance or imparting special functions is the processing process of textiles.
The after treatment method can be divided into two categories: physical/mechanical finishing and chemical finishing. According to the purpose of finishing and the different effects, it can be divided into basic finishing, appearance finishing and functional finishing.
Our after treatment products are mainly calendered, embossed and pearl paste printed fabrics.
The purpose of finishing:
1. The textile width is uniform, and the size and shape are stable. Such as heat setting.
2. Enhance the appearance of textiles: including increasing the gloss and whiteness of textiles, and enhancing or reducing the surface fluff of textiles. Such as heat setting, crinked/ creped, bubbled, mercerized.
3. Improve the feel of textiles: Chemical or mechanical methods are used to give textiles a comprehensive touch feel such as softness, smoothness, fullness, stiffness, lightness or thickness. Such as soft, stiff, weight gain and so on.
4. Improve the durability of textiles: mainly use chemical methods to prevent damage or erosion of fibers caused by sunlight, atmosphere or microorganisms, and prolong the service life of textiles. Such as anti-mite, anti-mildew finishing.
Give textiles special properties: including some protective properties or other special functions. Such as flame retardant, antibacterial, water repellent, oil repellent, anti-UV and antistatic.
