Environmental protection fabrics can be roughly divided into two categories: living environmental protection fabrics and industrial environmental protection fabrics.
Living environmental protection fabrics are generally composed of RPET fabrics, organic cotton, colored cotton, bamboo fiber, soybean protein fiber, hemp fiber, Modal, organic wool, log Tencel and other fabrics.
Industrial environmental protection fabrics are composed of inorganic non-metallic materials and metal materials such as PVC, polyester fiber, glass fiber, etc., and achieve the effect of environmental protection, energy saving and recycling in practical application.
Living
1.RPET fabric. RPET fabric is a new type of recycled environmentally friendly fabric, the full name is Recycled PET Fabric (recycled polyester fabric). Commonly known as Coke bottle environmental protection cloth. The fabric can be recycled and reused, which can save energy, oil consumption and reduce carbon dioxide emissions. For every pound of recycled RPET fabric, it can save 61,000 BTU of energy, which is equivalent to 21 pounds of carbon dioxide. After environmentally friendly dyeing, environmentally friendly coating, and calendering, the fabric can also pass the testing of international standards such as MTL, SGS, ITS, etc. Among them, phthalates (6P), formaldehyde, lead (Pb), polycyclic aromatic hydrocarbons, Environmental indicators such as nonkifen have reached European environmental protection standards and American environmental protection standards.
2. Organic cotton. Organic cotton is a kind of cotton produced in agricultural production, with organic fertilizers, biological control of pests and diseases, and natural farming management. Chemicals are not allowed. And based on the "Safety and Quality Standards for Agricultural Products" promulgated by various countries or WTO/FAO, the content of pesticides, heavy metals, nitrates, harmful organisms (including microorganisms, parasite eggs, etc.) and other toxic and harmful substances in cotton is controlled within the standard limit. inside, and certified commercial cotton.
3. Colored cotton. Colored cotton is a new type of cotton with natural colors of cotton fibers. Natural colored cotton is a new type of textile raw material cultivated by modern bioengineering technology. The fibers have natural color when the cotton is spun. Compared with ordinary cotton, it is soft, breathable, elastic and comfortable to wear. Therefore, it is also known as A higher level of ecological cotton. Internationally known as zero pollution (Zeropollution). Because organic cotton is grown and woven to maintain its natural properties, existing chemical synthetic dyes cannot dye it. Only use pure natural vegetable dyes for natural dyeing. Naturally dyed organic cotton has more colors and can meet more needs. Experts predict that in the early 21st century, brown and green will be the fashion colors of clothing. It embodies ecological, natural, leisure, fashion trends. In addition to brown and green, colored cotton garments are gradually being developed in blue, purple, gray-red, brown and other colors.
4. Bamboo fiber. Bamboo fiber yarn raw material is selected from bamboo as raw material, and the staple fiber yarn produced by bamboo pulp fiber is a green product. Unique style: wear resistance, no fuzz, high hygroscopicity and quick drying, high air permeability, good drape, smooth and plump hand feel, silky soft, anti-mildew, moth-proof and antibacterial, cool and comfortable to wear, and has the effect of beauty and skin care . Excellent dyeing performance, bright luster, and good natural antibacterial effect and environmental protection, conform to the trend of modern people's pursuit of health and comfort.
Of course, bamboo fiber fabrics also have some shortcomings. This plant fabric is weaker than other ordinary fabrics, the damage rate is higher, and the shrinkage rate is difficult to control. In order to overcome these defects, bamboo fibers are usually blended with some common fibers. Bamboo fibers are blended with other types of fibers in a specific proportion, which can not only reflect the properties of other fibers, but also give full play to the characteristics of bamboo fibers, bringing new characteristics to knitted fabrics. Pure spun and blended yarns (blended with Tencel, Modal, sweat-wicking polyester, negative oxygen ion polyester, corn fiber, cotton, acrylic and other fibers in different proportions) are the preferred fabrics for knitted close-fitting textiles. In trendy fashion, bamboo fiber fabrics are more effective for spring and summer clothing.
5. Soybean fiber. Soybean protein fiber is a degradable regenerated vegetable protein fiber, which has many excellent properties of natural fiber and chemical fiber. Its fabric has cashmere-like feel, silk-like luster and breathable warmth of cotton, skin-friendly and comfortable, and is praised as "21st century healthy and comfortable fiber" by domestic and foreign experts. 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, 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 pesticides and other chemical products cannot be used or only a small amount can be used. Organic fertilizers, biological control of pests and diseases, and natural cultivation are the main methods. From seeds to agricultural products, all natural and pollution-free products must be used. Organic cotton fabrics are about 50% more expensive than traditional fabrics.
6. Hemp fiber. Hemp fibers are fibers obtained from various hemp plants, including bast fibers of the cortex of dicotyledonous plants and leaf fibers of monocotyledonous plants, of annual or perennial herbs. The bast fiber crops mainly include ramie, jute, green hemp, hemp (hemp), flax, apocynum and kenaf. Among them, hemp, flax, apocynum and other cell walls are not lignified, and the thickness and length of the fibers are similar to cotton. 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%, and brittle than cotton fiber. Hemp and flax fibers have a smooth surface, which is easy to absorb moisture, and the moisture is released into the atmosphere faster; the fibers are relatively straight and not easily deformed.
7. Organic wool. Organic wool comes from chemical-free and GMO-free farms. These flocks are free-range and grown entirely in nature, making it a new topic of excitement for the wool industry, with interest in organic wool increasing significantly in recent months.
industrial
Generally, it is mainly based on environmentally friendly sunshine fabrics. Most of the processes on the market are divided into two categories: one is PVC coated fiber; the other is fiber impregnated in PVC. Generally, polyester fabrics are basically the covering method used in China. In foreign countries, more glass fiber fabrics are impregnated.
1. Flame retardant sunshade cloth: The shading effect basically reaches 85%-99%, the opening rate varies from 1% to 15%, and it has flame retardant function, which is generally flame retardant.
2. Embossed shade cloth: Embossed by special machine to achieve various pattern effects, and the styles of embossing are very rich
3. Jacquard shade cloth: through special process jacquard to achieve various pattern effects
4. Metal-coated shade cloth: The fabric is dyed and coated, the front is a sunny fabric, and the back is plated with a metal coating, including silver-plated, aluminum-plated, etc., which can achieve good air permeability and light transmission. At the same time, according to the principle of reflecting ultraviolet rays, the sunshade effect is better than that of ordinary pinhole sunlight fabrics.
