The main material is woven bags woven. The nonwoven fabric is a nonwoven fabric, it is the direct use of polymer chips, staple fibers or filaments forming the web by a variety of methods and techniques to form the consolidation of a soft, breathable and flat products, new fiber structure.
1 Introduction
Editor
Woven bags (also known as non-woven bag, English: Nonwoven bags) is a green product, tough and durable, attractive appearance, good ventilation, reusable, washable, can be screen printing advertising, logos, use of a long, suitable for any company in any industry as advertising, gift purposes. Consumers shopping at the same time get a fine non-woven bags, and businesses have been invisible advertising, best of both worlds, which makes non-woven fabrics are becoming increasingly popular in the market.
Woven products as raw materials, it is a new generation of environmentally friendly materials, with moisture, breathable, flexible, lightweight, non-combustion, easily biodegradable, non-toxic non-irritating, colorful, inexpensive, recyclable and so on. The material is placed outside the natural decomposition of 90 days, at the indoor life of up to five years, burning non-toxic, tasteless, and without any remaining material, so as not to pollute the environment, protect the earth is internationally recognized eco-environmentally friendly products.
Principle
Editor
The nonwoven fabric is a nonwoven fabric, it is the direct use of polymer chips, staple fibers or filaments forming the web by a variety of methods and techniques to form the consolidation of a soft, breathable and flat products, new fiber structure. Advantages compared to traditional woven bags plastic bags: woven bags cheap, environmentally friendly and practical, widely used, there is prominent advertising. Applicable to all types of business activities and exhibition fairs, enterprises and institutions is the ideal advertising promotional gifts.
The raw material is polypropylene woven bags, polyethylene and plastic raw materials, although the names of the two substances are similar, but are very different in chemical structure. The molecular structure of polyethylene having a very strong chemical stability, degradation is extremely difficult, so the decomposition of the plastic bag 300 years to complete; the chemical structure of polypropylene is not solid, the molecular chains can easily be broken, which can effectively degrade , and enter the next cycle in a non-toxic environment in the form of a non-woven bags in 90 days can be completely sub-
Solution.
Non-woven textile processes that do not need to make a non-fabric products like cloth, also called non-woven. Because it is just a short textile fibers or filaments randomly oriented or support columns, forming a fiber network structure and the use of mechanical, thermal or chemical methods such as reinforcement can be made. Most spunbond non-woven bags are made.
Simply say is this: one by one by a non-woven fabric is not interwoven yarn, knitting together, but the fibers are bonded together by direct physical methods, so when you get your clothes stick called , they will find that is not spare a root lint. Nonwovens breaking the traditional textile principle, and has a short process, production speed, high output, low cost, versatile, sources of raw materials and more features.
Fumo woven bags, fashion products using casting, composite solid, no glue in the composite process, soft, no plastic feel, no skin irritation, suitable for disposable medical single, sheets, gowns, gowns, protective clothing, shoe covers, and so the production of sanitary protection; This cloth bag called laminating non-woven bags.
Production
Editor
Spunlace nonwoven
The spunlace process is a high pressure water jet to the fine fiber web layer or layers, the fibers are entangled with each other, so that the reinforcing fiber network to have a certain strength.
Nonwoven heat
Thermally bonded nonwoven web is the added powdered or fibrous reinforcing material is a hot melt adhesive, the web was cooled and then melted by heating into the fabric reinforcement.
Airlaid
Can be called airlaid nonwoven wipes, dry paper non-woven. It is the use of airlaid technology will open pine wood fiber into a single fiber state and then the fiber agglutination method using flow on a net curtain, fiber network and then into the fabric reinforcement.
Wet Nonwoven
The wet nonwoven fabric was placed in an aqueous medium in loose fiber material into individual fibers open, while the different fiber raw materials are mixed, formed into a fiber pulp suspension, the pulp suspension into a web transport mechanism, the fibers in the wet state and then into a network reinforcement into cloth.
Spunbond nonwoven
Spunbonded non-woven fabric in the polymer was extruded, stretched to form a continuous filament, the filament is laid to the network, then through its own web bonding, thermal bonding, chemical bonding or mechanical reinforcement method that become woven webs.
Meltblown nonwoven
Meltblown nonwoven process: the polymer melt extrusion --- feeding --- forming --- fiber fiber network --- Cooling --- a reinforcement into cloth.
Needle-punched nonwoven
Woven dry needling a non-woven, non-woven fabric is the use of acupuncture needles puncture the role of the fluffy fiber mesh reinforcement into cloth.
Stitched nonwoven
Stitchbonded nonwoven fabric is a dry nonwoven fabric, stitch method is the use of warp-knit structure of the web winding, the yarn layer, nonwoven materials (such as plastic foil, metal foil, thin plastic, etc.) or a combination thereof Body reinforcement, to prepare a nonwoven fabric.
Use classification
Editor
According to product use can be divided into:
⒈ woven bags series: non-woven bags, woven bags, woven shopping bags.
⒉ non-woven bag series: non-woven paper bags, reusable shopping bags, packaging bags, non-woven bag.
⒊ woven products series: non-woven storage box, storage box non-woven, non-woven suit sets - woven suit sets.
⒋ Jewelry Bag Series: gift bag Drawstring bags jewelry bags flannel bags, jewelry bags, pencil bags perfume.
⒌ aprons Series: apron, polyester aprons, cotton aprons, PVC aprons, hanging apron.
10 four advantages
Editor
Non-woven bags are white trash instead of new products, new energy increases, the relevant departments to promote environmentally friendly energy, and increasingly serious environmental pollution, in order to get rid of this white pollution, to make our lives better, many environmentally conscious people think of a new product - non-woven bags, and its advantages are obvious. Woven cloth shopping bags are made of plastic non-woven fabric, a lot of people think that the cloth is called natural materials, but in fact is a misunderstanding. A stitchbonded nonwoven fabric bags are dry nonwoven fabric, stitch method is the use of warp-knit structure of the web winding, the yarn layer, nonwoven materials (such as plastic foil, metal foil, thin plastic, etc.) or their reinforcement assembly, to form a nonwoven fabric. Commonly used non-woven polypropylene material (abbreviation PP, commonly known as polypropylene) woven bags or polyethylene terephthalate (abbreviation PET, commonly known as PET), environmental protection and ordinary plastic shopping bags, as also can not be completely degraded. From the specific cost in terms of intensity under the same conditions as good as non-woven bags of plastic bags, but not waterproof, its price was higher than the bag several times as much. Acupuncture non-woven bags: a dry non-woven, non-woven fabric is the use of acupuncture needles puncture the role of the fluffy fiber mesh reinforcement into cloth. Especially with PP PE plastic shopping bags used, as are five common varieties of plastic, are used for 50 years can not degradable plastic varieties. Non-woven bag making capital mainly consists of two units, one is the cost of raw materials, and second bag processing costs. On the market city of love woven its specifications can buy very much, but the cost is not the same. Spunlace non-woven bags: a high-pressure water jet to fine one or more layers of fiber web, the fibers are entangled with each other, so that the fiber network to be reinforced and have a certain strength. Heat sealing woven bags: refers to adding fibrous webs or powdered hot melt adhesive reinforcement materials, fiber network and then cooling the heated melt into the fabric reinforcement. Non-woven bags are environmentally friendly products, it is more common kind of bags, mainly for shopping, packaging, advertising, electronics, clothing, decorations, and other products. The most important feature is that it has a non-woven plastic products do not have the environmental performance, which is far below the natural degradation time plastic bags, therefore, the use of non-woven fabrics made of non-woven bags have been recognized as the most affordable reusable shopping bags.
