Non-woven bags are not as good as plastic bags

Almost all domestic non-woven fabrics are made of man-made fibers such as polypropylene. In other words, domestic non-woven fabrics are plastic bags. As a result, those myths that are degradable and recyclable are self-defeating.A year ago, when the plastic restriction order came out, the”Environmentally friendly and degradable”The call for non-woven fabrics to replace plastic bags has never been heard. However, a year later, there are30%of nonwovens factories closed down,60%The factory warehouse of the factory is full of unsalable high-priced goods. The savior who eradicated the white trash has become a nobody”trash bag”.Nonwoven is not clothThe spraying machine spit out a pile of latitude and longitude lines that cannot be seen”cloth”, mostly white, some are black, after extrusion and shaping, according to1Meter1or1Meter6They are unprocessed non-woven bag blanks. The whole process is similar to that of pancakes, except that the raw materials are not flour and eggs, but polypropylene, viscose and other man-made fibers, which means that it is the same as a washing machine. , TVs and other home appliances shells are made of the same material, which is also plastic.The only difference is that most of the polypropylene pellets used to produce non-woven fabrics are second-hand, and a non-woven bag in the store may have been a laptop, monitor, or the shell of a washing machine in its previous life. Its present life is all kinds of man-made fibers mainly made of polypropylene. After melting, hot pressing and other steps, a pool of plastic sprayed by the spray machine, the fibers are oriented or randomly distributed, and they cannot be seen without combing. The traces of the cross after weaving the warp and weft yarns, so the non-woven fabric is called”non-woven”more acurrate.”pancakes”It is what Wenzhou Jichang Nonwoven Co., Ltd. does every day, and Lin Guoxi, the person in charge of the company, does it6Years of non-woven business, well versed in”pancakes”the biggest weakness of”not strong”. Injection molding machines, extruders and various rate meters strictly control the temperature, speed, and thickness of rayon forming. The thickness of non-woven fabrics is generally divided by grams, and the number of grams used as environmentally friendly shopping bags on the market is generally in45gram?100between grams.”Catalysts are essential, we have all kinds of catalysts, aluminum-containing ones, etc.”, in order to make the molecular weight of polypropylene fibers as small as possible. The molecular weight is small, the performance is unstable, and it will decompose when exposed to light and water.”Molecular weight is the key that non-woven fabrics are easier to degrade than plastic bags”. The molecular weight of the non-woven fabric produced by Lin Guoxi’s workshop is twice as small as that of ordinary plastic bags.”Load it with irregularly shaped heavy objects, such as a large bag of potatoes, it will be easily deformed by the object’s compression, and this deformation will not be easy to recover. “relatively degradable”‘Plastic Restriction Order’When it was first promulgated, business took off. Since then, more and more people have done it. Unexpectedly, the market demand has become smaller and smaller, and the company’s profit has plummeted this year.”Nonwovens factories in Guangdong and Zhejiang and Lin Guoxi’s companies face the same predicament. Dong Jinshi, executive vice president and secretary general of the International Food Packaging Association, predicted non-woven foam a year ago,”Nothing can replace plastic bags, and the degradability of non-woven fabrics is relative to plastic bags. “two or three hundred years and90It is the difference between the degradation years of plastic bags and non-woven fabrics. The difference of hundreds of years makes non-woven fabrics wear”degradable plastic bags”and”Environmental friendly”hat of. However, non-woven fabrics are used outdoors90It can degrade on its own in the sky, but it does not degrade to no trace, but becomes brittle fragments or powder like egg rolls. If placed indoors, the entire degradation process requires9year.whether 9year or 9 0sky,requires a condition—Sunlight is not enough if it is weak, it has to be strong light.”We have done experiments, hang the non-woven fabric under the sun, and it will be over in one summer,””finished”It means that the non-woven fabric is completely degraded. If there is no sunlight and stay indoors, it will take at least ten or even decades to degrade. Don’t forget that the degraded dust also contains color inks, which make the non-woven fabric colorful, and at the same time become toxic substances in the degraded dust. If it is sucked, it is also harmful to the human body.Non-woven fabric or troublesome fabricRecyclable and easy to degrade were once praiseworthy for non-woven fabrics. But like degradation, the recyclability of non-woven fabrics also has conditions. Don’t think that the non-woven fabric is dirty, just throw it into the washing machine just like the cloth. Cloth obviously can’t enjoy it. Most people who use non-woven fabrics discard it after it gets oily. Therefore, the recycling of non-woven fabrics is actually just an empty promise to the environment. The properties of non-woven fabrics also include water permeability and breathability. Due to these two characteristics, the items that non-woven fabrics can hold are limited. At the same time, since polypropylene will release toxic substances at high temperature, cooked food cannot directly contact non-woven fabrics, and can only be placed in special food bags made of polyethylene. The load-bearing capacity and strength of non-woven fabrics are not as good as those of plastic bags.”If the plastic bag is made as thick as the non-woven fabric, the plastic bag is much stronger than the non-woven fabric”Dong Jinshi explained. There are not many opportunities for non-woven fabrics to be really recycled, and each family has an average of10an idle non-woven bag, if this10If a non-woven bag is to continue to be recycled, it must always pay attention to moisture and sunlight. There are so many conditions that make the non-woven bag another name—Eco-friendly bags, some of them don’t live up to their name. It is no wonder that domestic30%of nonwovens factories closed down,60%The non-woven fabrics in the factory warehouse of the company are out of stock.Of course, the most important thing is cost, which is an insurmountable obstacle for non-woven fabrics. Merchants in the traditional farmers market prefer plastic bags. Since they are all plastic, of course merchants will not choose more expensive than plastic bags.10times the non-woven bag. In the final analysis, the cost issue is the real reason why the non-woven industry, which was a rising sun a year ago, has become a sunset red in an instant.
