01, living environmentally friendly fabrics:
Recycled polyester fabric
RPET fabric is a new type of recycled environmentally friendly fabric, the full name of Recycled PET Fabric (recycled polyester fabric), the raw material is RPET yarn made from recycled Baote bottle by product separation, slicing-spinning, cooling and collecting. Commonly known as Coke bottle environmental protection 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.
Organic cotton is mainly used in agricultural production, with organic fertilizers, biological control of pests and diseases, and natural farming management. 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.
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). Because organic cotton maintains its natural properties 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 colors such as blue, purple, gray red and brown.
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, soft, anti-mold, anti-bacterial, 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.
Soy protein fiber is a degradable, regenerative vegetable protein fiber that has many excellent properties of natural fibers 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 small amounts. Organic fertilizers, biological pests and diseases, and natural cultivation are the main factors. From seeds to agricultural products, they must be all natural and non-polluting. Organic cotton fabrics are about 50% more expensive than traditional fabrics.
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, flax 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 released to the atmosphere faster; the fiber is relatively straight and not easily deformed.
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. It is natural, degradable, and combines the natural texture of natural fabric with the practicality of synthetic fiber. It is soft to the touch, shiny like silk, smooth as skin, moisture-absorbing and breathable. The performance 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 difference is nearly half.
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 interest in organic wool has increased in recent months.
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 has a fairly good humidity control effect. According to fabric experts, this fabric has superior antistatic properties and does not feel attached to the body, so it is very slippery and is especially suitable for sports wear. Its moisture content is most in line with the physiological requirements of human skin, and has good gas permeability and humidity control function. It 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.
02, industrial environmental protection materials:
Generally, it is 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)
1. Flame-retardant sunshade: The shading effect is basically 85%-99%, the opening ratio is 1%-15%, and it has flame retardant function, which is generally permanent flame retardant effect.
2, embossed sunshade: through the special machine embossing, to achieve a variety of pattern effects, embossed style is very rich
3, jacquard sunshade: through the special process jacquard, to achieve a variety of pattern effects
4, metal coated sunshade: dyed coating on the fabric, the front is a sun fabric, the back is coated with a metal coating, including silver plating, aluminum plating, etc., can achieve a good breathable light transmission effect. At the same time, according to the principle of reflecting ultraviolet light, the sunshade effect of the general pinhole sunlight fabric is better.
Polyester is an important variety in synthetic fiber and is the trade name of polyester fiber in China. It is a fibril polymer prepared by esterification or transesterification and polycondensation of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG). —Polyglass is an inorganic non-metallic material with excellent performance and is an important part of glass fiber fabric. The original English name is: glass fiber. The components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, and the like. It is a process of melting, drawing, winding, weaving, etc. of glass balls or waste glass. Finally, various types of products are formed. The diameter of the glass fiber monofilament ranges from a few micrometers to twenty micrometers, which is equivalent to 1/20-1/5 of a hair strand. Each bundle of fiber strands has hundreds or even It consists of thousands of monofilaments, usually used as reinforcing materials in composite materials, electrical insulating materials and thermal insulation materials, circuit boards, etc., and is widely used in various fields of the national economy.
Chemical fiber is a fiber made from natural or synthetic high molecular materials. Depending on the source of the raw materials, it can be divided into rayon fibers using natural polymer materials as raw materials and synthetic fibers using synthetic polymer materials as raw materials.
