What is the weight of the total polyester fabric?

Environmentally friendly fabrics Classification of environmentally friendly fabrics can be broadly divided into two categories: living environmentally friendly fabrics and industrial environmentally friendly fabrics.

Living environmentally friendly fabrics are generally composed of RPET fabrics, organic cotton, colored cotton, bamboo fibers, soy protein fiber, hemp fiber, Modal, organic wool, and wood Tencel.

Industrial environmentally friendly fabrics consist of inorganic non-metallic materials such as PVC, polyester fiber, and glass fiber, and metal materials, which achieve environmental protection, energy saving, and recycling effects in practical applications.

Living environmentally friendly fabric

1.RPET fabric. RPET fabric is a new type of recycled eco-friendly fabric, the full name of Recycled PET Fabric. Its raw material is RPET yarn made from recycled Baote bottle by quality inspection, slicing-spinning, cooling and collecting. Commonly known as Coke bottle environmentally friendly cloth. The fabric can be recycled and reused to save energy, oil consumption and reduce carbon dioxide emissions. Each pound of recycled RPET fabric can save 61,000 BTU of energy, equivalent to 21 pounds of carbon dioxide. After environmentally friendly dyeing, environmentally friendly coating and calendering, the fabrics can also be tested by international standards such as MTL, SGS and ITS, among which phthalates (6P), formaldehyde, lead (Pb), polycyclic aromatic hydrocarbons, Environmental indicators such as 壬基芬 meet the latest European environmental standards and the latest US environmental standards.

2. Organic cotton. Organic cotton is mainly used in agricultural production, mainly based on organic fertilizers, biological control of pests and diseases, and natural farming. It is not allowed to use chemical products, from seeds to agricultural products, all natural and pollution-free cotton. Based on the “Agricultural Product Safety Quality Standards” promulgated by countries or WTO/FAO, the content of toxic and hazardous substances such as pesticides, heavy metals, nitrates and harmful organisms (including microorganisms, parasite eggs, etc.) in cotton is controlled within the standard limit. Inside, and get certified commodity cotton.

3. Colored cotton. Colored cotton is a new type of cotton with natural color of cotton fibers. Natural colored cotton is a new type of textile material that has been cultivated with modern bioengineering technology and has natural color in the fiber of cotton. It is soft, breathable, elastic and comfortable to wear compared with ordinary cotton. A higher level of ecological cotton. Internationally known as Zero Pollution (Zeropollution). Due to the inherent nature of organic cotton during planting and weaving, existing chemical synthetic dyes cannot be dyed. Only natural dyes are used for natural dyeing. Naturally dyed organic cotton has more colors to meet more needs. According to experts, in the early 21st century, brown and green will be the popular colors of clothing. It embodies ecological, natural, leisure and fashion trends. In addition to brown and green, colored cotton garments are gradually developing varieties of blue, purple, gray red, brown and other colors.

4. Bamboo fiber. The raw material of bamboo fiber yarn is made of bamboo, and the staple fiber yarn produced by bamboo pulp fiber is a green product. The knitted fabric and garment made of cotton yarn made from the raw material are obviously different from cotton and wood cellulose fiber. Unique style: wear resistance, lint-free ball, high hygroscopicity, fast drying, high breathability, excellent drape, smooth and full-feeling, silky soft, anti-mold, anti-mite, anti-bacterial, cool and comfortable. . It has excellent dyeing performance, bright luster, good natural antibacterial effect and environmental protection, and conforms to the trend of modern people pursuing health and comfort.

Of course, bamboo fiber fabrics also have some shortcomings. This plant fabric is more delicate than other common fabrics, the damage rate is higher, and the shrinkage rate is more difficult to control. To overcome these drawbacks, bamboo fibers are usually blended with some common fibers. The blending of bamboo fiber with other kinds of fibers in a specific ratio can not only reflect the performance of other fibers, but also fully utilize the characteristics of bamboo fibers, bringing new features to knitted fabrics. Pure and blended yarns (mixed with different kinds of different kinds of fibers, such as Tencel, Modal, Perspiration Polyester, Negative Oxygen Polyester, Corn Fiber, Cotton, Acrylic Fiber, etc.), are the fabric of choice for knitted close-fitting textiles. In the trend fashion, the spring and summer clothes of bamboo fiber fabrics are more effective.

5. Soy fiber. Soybean fiber is a degradable, regenerative vegetable protein fiber that has many excellent properties of natural and chemical fibers. Its fabric has a cashmere-like feel, silky luster and cotton breathability and warmth. It is skin-friendly and has been praised by domestic and foreign experts as "21st century healthy and comfortable fiber". Soybean protein fiber is similar to silk, with good drape and fine surface texture. It is an ideal fabric for high-end shirts. It also contains a variety of essential amino acids that are suitable for wearing. China is the third largest organic cotton producer in the world after Turkey and India, and Xinjiang is the main production center. In the process of planting organic cotton, chemical insecticides and other chemical products cannot be used or can be used in a small amount. Organic fertilizers, biological pests and diseases, and natural cultivation are the main factors. From seeds to agricultural products, they must be completely natural and non-polluting. Organic cotton fabrics are about 50% more expensive than traditional fabrics.

6. Hemp fiber. Hemp fiber is a fiber obtained from various hemp plants, including the bast fiber of the annual or perennial herb dicotyledon cortex and the leaf fiber of the monocot. The bast fiber crops are mainly ramie, jute, ramie, ** (hemp), flax, apocynum and ramie. Among them, the cell walls such as hemp, linen and apocynum are not lignified, and the fibers are thick and slender and short, similar to cotton. They can be used as textile raw materials, woven into various cool linens and summer cloths, and can also be blended with cotton, wool, silk or chemical fiber. The strength of hemp fiber is higher than that of cotton fiber, up to 6.5 g/denier; the elongation is small, only half of cotton fiber, about 3.5%, more brittle than cotton fiber. The surface of hemp and flax fiber is smooth, and it is easy to adsorb moisture. The moisture is emitted to the atmosphere faster; the fiber is relatively straight and not easily deformed.

7. Modal. Modal is also a common environmentally friendly fabric from the Austrian company Lannzing, which is commonly used in high-end underwear. Modal fiber is a Lyocell fiber made from eucalyptus wood. It is natural and degradable. It combines the natural texture of natural fabric with the practicality of synthetic fiber. It is soft to the touch, shiny like silk, smooth as **, moisture absorption, Breathability is better than cotton, and it is easier to dye than bamboo fiber fabric. After repeated washing, the color is still full and bright. According to Shaoxing Jinyu, the price of imported modal fabric per kilogram is more than 7.04 US dollars, while Taiwan's Modal is only about 4.23 US dollars, the price difference is nearly half.

8. Organic wool. Organic wool is produced on farms without chemicals and GMOs. The stocking of these flocks, which grow entirely in nature, has become a new topic of excitement for the wool industry, and the market's interest in organic wool has increased in recent months.

9.Viscose (Logis Tencel): It is a kind of sports-friendly fabric. Because of its special nano-thread molecular structure, it is like the air circulation pipe on the surface of the fabric, ensuring sufficient oxygen circulation and locking moisture, so it is quite good. The humidity control effect. Some fabric experts pointed out that this fabric has superior anti-static properties, does not produce a feeling of adhesion to the body, and is therefore very smooth, especially suitable for sports wear. Its moisture content is most in line with the physiological requirements of human skin, has good gas permeability and humidity control function, and is consistently referred to as “breathing fabric” by domestic and foreign media. Its fabric has the advantages of soft hand, smooth and cool, breathable, antistatic, and dyed.

Industrial environmentally friendly materials are generally based on environmentally friendly sun fabrics. The processes on the market are mostly divided into two categories: one is PVC coated fiber; the other is fiber impregnated PVC. Generally, polyester fabrics are basically used in the domestic coating method (such as: US BANGIA PANGEAE sun fabric). In foreign countries, glass fiber fabrics are more impregnated (eg: Spanish CITEL sun fabric)
