The definition of environmentally friendly fabrics is very broad, which is also due to the breadth of the definition of fabrics. Generally, environmentally friendly fabrics can be considered as low-carbon, energy-saving, naturally free of harmful substances, and environmentally friendly and recyclable. 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 environment-friendly fabrics:
1. Recycled polyester 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 the latest European environmental protection standards and the latest US 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, in which the fibers have natural colors 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. Soy Fiber
Soybean protein fiber is a degradable regenerated vegetable protein fiber, which has many excellent properties of natural fiber and chemical fiber. Its fabrics have cashmere-like feel, silk-like luster, and cotton's breathable and warm properties, which are skin-friendly and comfortable. 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 annual or perennial herb dicots and leaf fibers of monocots. The bast fiber crops mainly include ramie, jute, green 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 those of 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. Modal
Modal is also a common environmentally friendly fabric, which comes from the Austrian company Lanzing and is often used in high-end underwear. Modal fiber is Lyocell fiber made of beech wood. It is pure natural and degradable. It combines the gorgeous texture of natural fabrics and the practicality of synthetic fibers. It is soft to the touch, shiny like silk, smooth like baby skin, hygroscopic, The air permeability is better than that of cotton, and at the same time, it is easier to dye than bamboo fiber fabrics, and the color is still full and bright after repeated washing.
8. 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 environmental protection material
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 (such as: American Bangea PANGEAE sunshine fabric).
1. Flame retardant sunshade cloth: The shading effect basically reaches 85%-99%, the opening rate varies from 1% to 15%, and it has a flame retardant function, which is generally a permanent flame retardant effect. 2. Embossed sunshade cloth: Embossed by special machine to achieve various pattern effects, and the embossed styles are very rich 3. Jacquard sunshade cloth: Jacquard through a special process to achieve various pattern effects 4. Metal-coated sunshade cloth: Yes The fabric is dyed and coated, the front is a sunshine fabric, and the back is plated with a metal coating, including silver plating, aluminum plating, etc., which can achieve a good air permeability and light transmission effect. At the same time, according to the principle of reflecting ultraviolet rays, the sunshade effect is better than that of ordinary pinhole sunlight fabrics.
Composition:
Polyester is an important variety of synthetic fibers. It is a fiber high polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reaction. -Polyglass fiber is an inorganic non-metallic material with excellent performance, and is an important part of glass fiber fabrics. English original name: glass fiber. The ingredients are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. It uses glass balls or waste glass as raw materials through high temperature melting, wire drawing, winding, weaving and other processes. Finally, various products are formed. The diameter of glass fiber monofilament ranges from a few microns to more than 20 meters of microns, which is equivalent to 1/20-1/5 of a hair. It is composed of thousands of monofilaments, and is usually used as a reinforcing material in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates, etc., and is widely used in various fields of the national economy.
Chemical fiber is a fiber made of natural or synthetic polymer substances as raw materials. According to the source of raw materials, it can be divided into man-made fibers using natural polymer substances as raw materials and synthetic fibers using synthetic polymer substances as raw materials.
