China's clothing core standards are backward, putting the cart before the horse and restricting development

China's clothing core standards are backward, putting the cart before the horse and restricting development

(Summary description)Domestic textile exports are restricted 　　 At the beginning of this month, the escalation of two EU chemical restrictions has caused many Chinese manufacturers who rely on exports to complain. The new regulations further restrict the content of “polycyclic aromatic hydrocarbons” and ban “azo dyes”. The two restrictions involve toys, clothing, bedding, shoes, towels, wigs, hats and other categories. Although the public is not familiar with the names of these chemicals, they are exposed to them almost every day. For example, "Azo dyes" are the most widely used synthetic dyes in the dyeing and printing process of textiles and leather products. They have been listed as banned by Europe, America and Japan, but they are not banned in China. 　　According to a reporter from Beijing Business Daily, while the EU standards are becoming increasingly stringent, domestic clothing manufacturers have also begun to improve the quality of their clothing. "In fact, it is not difficult to do this. Although the cost will increase slightly, the impact will not be significant. It's just that there is no such requirement in China, so the garment factory does not ask for trouble." An insider said.

Application

Application of newly developed auxiliaries for printing and dyeing materials

Environmentally-friendly oxygen bleaching stabilizers and environmentally-friendly chelating agents. Compounds that have been used more in oxygen bleaching stabilizers and chelating agents in the past include nitrogen triacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA) and diethylenetriamine Acetic acid (DTPA), etc., although they have good effects, they have very poor biodegradability after chelating metals; therefore, European laws have banned their use in recent years, and newly developed diethylenetriamine pentaethylene phosphonic acid (DTPMP), Environmentally friendly chelating agents such as sodium acrylate (PASS), this new additive has strong metal ion complexing ability and excellent descaling effect, is also easy to biodegrade, and will not cause environmental pollution. At present, the products that have entered the market include PrestogenPL, Mirokai54H and so on. The chelating agent S produced in my country is also an environmentally friendly chelating agent composed of organic phosphonates as the main material and supplemented by special synergistic ingredients, and its performance has reached the level of similar foreign products. Biological enzyme preparations are used for fabric pre-treatment, and they are easily degraded, which has little impact on the environment. At present, amylase has been used for desizing treatment, cellulase is used for smoothing and weight reduction, and pectinase and cellulase are used for scouring of cotton fiber. The main products in this area are Cellusoft, a cellulase, used for smooth and soft finishing of cotton, linen, Tencel and other fabrics; BioPrep, a pectinase, used for scouring of cotton, can replace the traditional strong Alkaline cooking process; IND-80L, also a pectinase, used for cotton scouring; IND-88L, a cellulase, can form a composite enzyme with IND-80L for cotton scouring. For example, the use of a composite enzyme composed of pectinase IND-80L and cellulase IND-88L for enzymatic-hydrogen peroxide scouring and bleaching of cotton fibers can obtain the same wetting effect, dyeability and uniformity as the traditional alkali-hydrogen peroxide scouring and bleaching process. Dyeing <5>. Environmentally-friendly dispersants are most commonly used in the field of dispersants are the condensates of sulfonic acid compounds of naphthalene and its homologues and formaldehyde, such as dispersant NNO, dispersant MF, dispersant CNF, etc. These products are produced in the manufacturing process Only 25% and 30% of the wastewater can be biodegraded during treatment. In recent years, the German BASF company has successfully developed a new environmentally friendly dispersant SetamolE, which is a mixture of aromatic sulfonic acid and sodium carboxylate. In addition to excellent dispersibility, it also has good biodegradability. It has been widely used in dye applications. In addition, the application of lignosulfonate dispersants, such as dispersant W, is also expanding.

Textile futuristic aiming at low energy consumption

Bark fabric Many people in the industry believe that obtaining textiles from trees would be a good way to reduce pollution. The BARKTEX company produces the oldest textile known to mankind, the traditional "bark clothing". It can be widely used in clothes, furniture and interior design. After peeling the bark from the tree, new bark grows again. From a humanistic point of view, the developed bark textile has the characteristics of low water volume and low energy consumption, and is environmentally friendly and ecologically suitable. Mushroom material Scientists are actively looking for alternative plastic foam packaging materials that harm the ecological environment. At present, mushroom materials with environmental protection properties are one of the ideal materials. Ecovative combines mycelium with agricultural by-products and can customize packaging insulation materials with sustainability, biodegradability and low-cost competitiveness.

How

How to choose a good woolen sweater technical points

There are many ways to identify fibers, which can be summarized into two categories. One is a more intuitive sensory identification method, and the other is to use various fibers with different physical and chemical properties to perform certain tests to achieve the purpose of identification. The more commonly used methods are combustion method, microscope identification method and solvent solution method. (1) Sensory identification method. This method does not need to use any objects or equipment, according to * own intuition, long-term work experience, according to the fabric feel and suede to identify. The fiber length of rabbit hair is generally 30-50 mm. There are many rabbit hair fibers, which means that the proportion of rabbit ingredients is high and the products are high-end. Wool sweaters and acrylic sweaters (commonly known as fake wool sweaters), because acrylic fibers have unique characteristics like wool, it can be difficult to distinguish. But as long as you carefully observe and compare differences, there are still differences. Intuitively speaking, wool products are relatively soft and elastic, with a large specificity and soft color. (2) Combustion method. Wool products, when burning, smoke and blisters while burning, accompanied by the smell of singeing hair, a lot of ash, shiny black must be brittle and lump. Acrylic fiber products, when burning, slowly burn while melting, the flame is white, bright and powerful, slightly black smoke, fishy smell, gray in white spherical shape, brittle and fragile. Nylon products burn slowly while melting. There is a slight white smoke when burning. The flame is blue and has a celery fragrance. It is light brown and hard, not easy to twist. The difference between wool and cashmere 1. The scale arrangement of fine wool is denser and thicker than that of cashmere, and its milling property is greater than that of cashmere. 2. The curl of fine wool is greater than that of cashmere. 3. The leather content of cashmere is higher than that of fine wool, and the rigidity of cashmere fiber is better than that of fine wool, that is, cashmere is softer than fine wool. 4. The warmth retention of cashmere is stronger than that of fine wool. 5. The unevenness of fineness of cashmere is smaller than that of fine wool, and the appearance quality of its products is better than that of fine wool. 6. The density of cashmere is lower than that of fine wool, and its products are lighter and thinner than fine wool products. 7. Fine wool has better acid and alkali resistance than cashmere, and is less damaged than cashmere when exposed to oxidants and reducing agents. 8. Generally, fine wool products have better pilling resistance than cashmere products, but the felting shrinkage is greater.
