Nonwovens Have A Very Strong Stability
Non-woven bags to non-woven fabrics as raw materials, it is a new generation of environmentally friendly materials, with moisture, breathable, flexible, light, non-combustion, easy to break down, non-toxic non-irritating, rich colors, low prices, And so on. The material is placed in the outdoor 90 days can be natural decomposition, Non Woven Bag placed in the indoor life of up to 5 years, burning non-toxic, tasteless, and without any legacy material, which does not pollute the environment, internationally recognized as the protection of the Earth's ecological products.
Non-woven bags are mainly used in shopping malls supermarket shopping, clothing packaging, shoes packaging, food and other non-woven bags.
Non-woven bags (also known as non-woven bags), is a green product, also known as non-woven bags, non-woven shopping bags, non-woven bags, non-woven bags. The main component of non-woven fabric is PP (polypropylene), the fabric has a variety of colors available for customers to choose, bag size, thickness, Non Woven Bag style can be specified by the customer. Can withstand silk screen printing machine and other printing process, logo logo and text can also be printed according to customer requirements, Non Woven Bag while the product tough and durable, handsome in appearance, good ventilation, can be reused, can be washed, silk screen advertising, long.
Non-woven bag classification
1, non-woven bags of the main material is non-woven. The nonwoven fabric is a nonwoven fabric which utilizes high polymer chips, short fibers or filaments to form new fibrous products with a soft, breathable and planar structure formed by a variety of web forming methods and consolidation techniques. Advantages: non-woven bags cheap, environmentally friendly and practical, widely used, Non Woven Bag there are prominent advertising position. Applicable to all kinds of business activities and exhibition trade fairs, enterprises and institutions is the ideal advertising promotional gifts.
2, non-woven raw materials are polypropylene, and plastic bags of raw materials are polyethylene, although the two substances similar to the name, but the chemical structure is very different. Non Woven Bag Polyethylene chemical molecular structure has a very strong stability, very difficult to degrade, so the plastic bags need 300 years to break down; and polypropylene chemical structure is not strong, the molecular chain is easy to break, which can be effectively degraded , And in the non-toxic form into the next environmental cycle, Non Woven Bag a non-woven bags in 90 days can be completely decomposed.
Third, according to the different production processes can be divided into:
1, spunlace: the high-pressure micro-jet is sprayed to one or more layers of fiber network, so that the fibers tangled together, so that the fiber can be reinforced with a certain strength.
2, heat non-woven bags: refers to the fiber in the fiber or powder-like hot-melt adhesive reinforcement materials, fiber and then heated by heating and cooling into a cloth.
3, pulp air into the network non-woven bags: also known as clean paper, dry paper nonwovens. It is the use of air-laid technology to open the wood pulp fiber board into a single fiber state, and then use the air flow method to agglutinate the fiber into the net curtain, the fiber mesh and then reinforce into. 4, wet non-woven bags: is placed in the water medium of fiber raw materials open into a single fiber, Non Woven Bag while mixing different fiber raw materials, made of fiber suspension pulp, suspended pulp transported to the network mechanism, Non Woven Bag fiber in the wet Into the network and then reinforce into cloth.
5, spunbond non-woven bags: the polymer has been extruded, stretching and the formation of continuous filament, the filament laying into a net, the fiber mesh and then through their own bonding, thermal bonding, chemical bonding or mechanical The reinforcement method makes the web into a nonwoven fabric.
6, meltblown non-woven bags: the process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- into a network --- reinforced into cloth.
7, acupuncture: dry non-woven fabric, Non Woven Bag acupuncture non-woven fabric is the use of puncture needle puncture, the fluffy fiber reinforced into a cloth.
8, stitching: is a dry non-woven fabric, sewing method is the use of warp knitting structure of the network, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination The body is reinforced to form a nonwoven fabric.
