[Brief description] Is non-woven fabric cloth or not? Why is it called "non-woven fabric"? The raw material of non-woven fabric bags is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are very different. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so it takes 300 years for plastic bags to decompose; However, the chemical structure of polypropylene is not firm, and the molecular chain can be easily broken, which can be effectively degraded, and enter the next environmental cycle in a non-toxic form. A non-woven fabric product (non-woven fabric bag) is at 90
Is non-woven fabric cloth or not? Why is it called "non-woven fabric"?
Decomposition: The raw material of nonwoven cloth bag is polypropylene, while the raw material of plastic bag is polyethylene. Although the names of the two substances are similar, their chemical structures are very different. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so it takes 300 years for plastic bags to decompose; However, the chemical structure of polypropylene is not firm, and the molecular chain can be easily broken, which can be effectively degraded, and enter the next environmental cycle in a non-toxic form. A non-woven fabric product (non-woven fabric bag) can be completely decomposed within 90 days.
　　Non-woven bags are classified by use:
　　1. Advertising bag
　　Shopping bag advertising can use the limited area of the bag body to spread the market information of enterprises or products and services to the world. When customers carry shopping bags printed with shop advertisements and walk through the streets, they are actually some exquisite advertising bags, which are no less than making an excellent advertising sign, but the cost is relatively low.
　　2. Knowledge advertising bag.
　　It is to print various patterns and characters with certain knowledge, such as world famous paintings and Chinese calligraphy, on the shopping bag. Such shopping bags not only provide convenience for consumers when carrying goods, but also cultivate people's sentiment and make people have wonderful psychological feelings.
　3. Gift advertising bag。
　　China is a country of etiquette. People always bring gifts to "walk and walk" to connect feelings and set off the atmosphere during New Year's festivals and birthday greetings. When the guest carries the gift in a shopping bag printed with the words "Wish you a long life", "Wish you a happy life" and so on, the host feels not only the gift, but also another kind of interest in his heart.
　　4. Commemorative advertising bag.
　　as ×× Art festival commemoration, tourism souvenir bag, etc. This strategy caters to people's psychology of commemoration and honor, and makes people have a new feeling after shopping.
　　5. Simple advertising bag 　　When customers buy miscellaneous things and need a simple shopping bag to hold them, if the store can provide one to solve people's worries, it will be welcomed by consumers. Convenience is an important key to sales promotion.
　　6. Time-seeking advertising bag
　　Nowadays, people generally pursue a high standard of lifestyle, and fashionable goods lead the consumption trend for a time. When there is something "hot" in the society, if the shopkeeper prints the product design and promotional information on the beautiful shopping bag, it is undoubtedly an important way to promote sales. When consumers see that hot goods are available in a store, they also have an "irresistible temptation".
　7. Antique advertising bag. Many traditional commodities with high social awareness are popular with consumers because of their exquisite materials, sophisticated production and long history. If the shopping bag is printed with simple and elegant patterns and words, it will give people a noble and solemn feeling, and it will certainly arouse the shopping interest of some consumers. 　　It can be divided into:
　　1. Spunlage: It is to spray high-pressure micro-water into one or more layers of fiber mesh, so that the fibers are intertwined with each other, so that the fiber mesh can be strengthened and have a certain strength
2. Heat-bonded non-woven fabric bag: It refers to adding fibrous or powdery hot-melt adhesive reinforcement material into the fiber mesh, and then heating, melting and cooling the fiber mesh to form a cloth
3. Pulp air-flow non-woven fabric bag: also known as dust-free paper and dry paper non-woven fabric. It uses the air flow web forming technology to loosen the wood pulp fiberboard into a single fiber state, and then uses the air flow method to make the fibers agglomerate on the web curtain, and then the fiber mesh is reinforced into a cloth
4. Wet non-woven fabric bag: It is to loosen the fiber raw materials placed in the water medium into a single fiber, and mix different fiber raw materials at the same time to make a fiber suspension slurry. The suspension slurry is transported to the mesh forming mechanism, and the fiber is formed into a mesh in the wet state and then consolidated into a cloth
5. Spunbonded non-woven fabric bag: after the polymer has been extruded and stretched to form continuous filament, the filament is laid into a net, and then the fiber net is changed into non-woven fabric through self-bonding, thermal bonding, chemical bonding or mechanical reinforcement
6. Melt-blown non-woven fabric bag: its process: polymer feeding - melt extrusion - fiber forming - fiber cooling - mesh forming - reinforcement and cloth forming
7. Needling: It is a kind of dry-process non-woven fabric. Needling non-woven fabric uses the puncture effect of the needle to reinforce the fluffy fiber mesh into a cloth
8. Stitching: It is a kind of dry non-woven fabric. Stitching is to use the warp knitting coil structure to reinforce the fiber mesh, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination to make non-woven fabric
It can be divided into: 1. Non-woven bag series: non-woven environmental protection bag, non-woven handbag, non-woven shopping bag, etc.
。 2. Non-woven bag series: non-woven document bag, environmental shopping bag, packaging bag, non-woven handbag< br> 3. Non-woven products series: non-woven storage box, non-woven storage box, non-woven suit set - non-woven suit set
4. Jewelry bag series: gift bags, rope bags, jewelry bags, velvet cloth bags, perfume bags, pen bags, jewelry bags, etc
5. Apron series: advertising apron, polyester apron, cotton apron, PVC apron, hanging net apron
Use of non-woven bag:
　　Non-woven bags: As a member of the "Alliance for Reducing Plastic Bags", he once mentioned that non-woven bags have been used when he proposed to reduce the use of plastic bags to the relevant government departments. Now the government has officially issued the "plastic prohibition order" to promote non-woven bags rapidly, but many problems have been found based on the current use situation:
　　1. In order to reduce costs, many enterprises print patterns on non-woven bags, which is harmful to human health. I have talked about whether the printing of environmental protection bags is environmentally friendly in other topics.
　　2. The large distribution of non-woven bags has made the number of non-woven bags in some homes almost exceed that of plastic bags, which is a waste of resources
　3. Non-woven fabrics are not environmentally friendly in terms of texture, because they are made of polypropylene and polyethylene, which are difficult to degrade. The reason for promoting them is that they are environmentally friendly because of their thickness ratio The plastic bag is high and flexible, which is conducive to reuse. It can be recycled and reused. This kind of cloth bag is suitable for companies that are not very strong and want to promote environmental protection as a substitute for the former plastic bags and paper bags. It is also practical to promote free distribution in exhibitions and activities. Of course, the effect is proportional to the style and quality of their own production. If it is too bad, be careful that others use it as garbage bags.
Production process of non-woven bag
　　Non-woven cloth bags generally adopt the screen printing process, which is often referred to as "screen printing", which has always been a common printing process for many manufacturers. However, with the increasing demand of customers for the exquisite printing and environmental protection of products, many new non-woven printing methods have emerged. Here we introduce several mainstream printing methods in the current market:
　　1、 Watermark
　It is named because it uses water-based elastic glue as the printing medium. It is common in textile printing, also called printing. Mix the color paste and water-based elastic glue when printing. The printing plate can be washed directly with water without chemical solvent. It is characterized by good coloring power, strong covering and fastness, water resistance, and basically no odor.
　　2、 Intaglio printing
　　The finished product processed by this method is usually called non-woven fabric bag. This process is divided into two steps, that is, first use the traditional intaglio printing process to print the pictures and texts on the film, and then use the film covering process to composite the film with the patterns on the non-woven fabric. This process is generally used for non-woven bags with large area color pattern printing. It is characterized by exquisite printing, whole-process machine production and short production cycle. In addition, the product has excellent waterproof performance, and the durability of the finished product is also better than that of non-woven bags produced by other processes. The film is available in bright and matte, and matte has frosting effect! The disadvantage is that it conflicts with the concept of environmental protection, because the film is difficult to degrade.
　　3、 Heat transfer printing
　　Heat transfer printing belongs to special printing in printing! This method requires an intermediate medium, that is, first print the image and text onto the heat transfer film or paper, and then transfer the pattern onto the non-woven fabric through the heat transfer equipment. The commonly used medium in textile printing is heat transfer film. Its advantages are: exquisite printing, rich layers, comparable to photos. Suitable for small area color image printing. The disadvantages are high price and high printing cost.
　　Four advantages of non-woven bag
　　The environment-friendly non-woven fabric bag (commonly known as non-woven fabric bag) is a green product, which is tough and durable, beautiful in shape, good in breathability, reusable, washable, can be used for screen printing advertising, and has a long service life. It is suitable for any company and any industry as advertising and gift.
　A non-woven shopping bag has more economic effect
　　Since the release of the plastic restriction order, plastic bags will gradually withdraw from the packaging market of goods and be replaced by reusable non-woven shopping bags. Compared with plastic bags, non-woven fabric bags are easier to print patterns and have more vivid color expression. In addition, the non-woven shopping bag can be used repeatedly. It can be considered to add more beautiful patterns and advertisements than plastic bags. Because the wear rate of the non-woven shopping bag is lower than plastic bags, the non-woven shopping bag will save more costs and bring more obvious advertising benefits.
　II. Non-woven shopping bags are more solid
Traditional plastic shopping bags are thin and easy to be damaged in order to save costs. But if we want to make him stronger, we must spend more money. Non-woven shopping bags have solved all problems. Non-woven shopping bags have strong toughness and are not easy to wear. There are also many plastic coated non-woven shopping bags, which are not only strong, but also waterproof, feel good, and have a beautiful appearance. Although the cost of a single bag is a little higher than that of plastic bags, the service life of a non-woven shopping bag can reach hundreds, even thousands of plastic bags.
　Three non-woven shopping bags have more advertising effect
　　A beautiful non-woven shopping bag is not just a packaging bag for goods. Its exquisite appearance is even more unforgettable. It can be transformed into a fashionable and simple shoulder bag and become a beautiful scenery on the street. In addition, its solid, waterproof and non-stick characteristics will become the first choice for customers to go out. If you can print your company's logo or advertisement on such a non-woven shopping bag, its advertising effect is self-evident, and it really turns small investment into big return.
　　IV. Non-woven shopping bags have more environmental protection and public welfare value
　The plastic restriction order was issued to solve the problem of environmental protection. The overturning use of non-woven bags greatly reduces the pressure of garbage transformation. With the concept of environmental protection, it can better reflect the image of your company and the effect of being friendly to the people. The potential value brought by this is more than money can replace.
