Production principle of non-woven bags
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 and non-irritating, colorful, inexpensive, recyclable and so on. The material placed outside the natural decomposition of 90 days, placed in the indoor life of up to 5 years, burning non-toxic, tasteless, and without any remaining material, so as not to pollute the environment, is internationally recognized as Earth's ecological environmental protection products.
Non-woven is a non-woven fabric, it is the direct use of polymer chips, staple fiber or filament fiber network formed by various methods and consolidation techniques to form a soft, breathable and new fiber products planar structure. Advantages compared to conventional non-woven bags plastic bags: woven bags cheap, environmentally friendly and practical, widely used, a prominent advertising position. Applicable to all types of business activities and exhibition fairs, enterprises and institutions is the ideal advertising promotional gifts.
The raw materials of Non-woven bags are polypropylene, polyethylene and plastic raw materials, although the names of the two substances are similar in chemical structure but very different. Polyethylene chemical molecular structure has a very strong stability, extremely difficult to degrade, so plastic bags need 300 years to decompose completed; and the chemical structure of polypropylene is not solid, the molecular chain can easily be broken, which can effectively degrade and enter the next cycle in the form of a non-toxic environment, and a non-woven bags in 90 days, can be completely decomposed.
The process of Non-woven textile is not required to make a non-fabric products like cloth, also called non-woven. Because it is just short fibers or filaments of textile or random orientation support column structure formed web, and mechanical, thermal or chemical methods such as reinforcement can be made. Most non-woven bags are spunbond nonwoven fabric.
Simply say is this: a non-woven fabric is not intertwined by a single yarn, knitting together, but the fibers are bonded together by direct physical methods, so when you get your clothes stick said (now generally referred to stick with non-woven fabric), you will find that is not spare a root of the thread. 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, products using the casting mode, composite solid, not in the composite process viscose, soft, no plastic feeling, no skin irritation, apply to single disposable medical, sheets, surgical gowns, Geli Fu, protective clothing, shoe covers, and other health protective equipment production; kind of cloth bag called laminating non-woven bags.
Eight kinds of technology of non-woven bags
1, spunlace
Spunlace process is the high-pressure water jet to a fine one or more layers of fiber web, the fibers tangled with each other, whereby the fiber network to have a certain strength and reinforcement.
2, non-woven heat
Thermally bonded nonwoven fabric refers to adding web fibrous or powdered hot melt adhesive reinforcement materials, fiber network and then cooled after heating and melting the reinforcement into cloth.
3, airlaid nonwoven
Airlaid nonwoven fabrics can be called airlaid dry papermaking nonwoven fabric. It is the use of airlaid technology wood pulp fiberboard opener into a single fiber state, and then use the airflow method on the fiber aggregation into a network of screens, fiber network and then reinforcement into cloth.
4, non-woven wet
Wet nonwoven fabric is placed in an aqueous medium fiber material opening into a single fiber, while the mixing of different fiber materials, made of pulp fiber suspensions, suspended pulp conveyor into a network of institutions to the fibers in the wet state into a network again reinforcement into cloth.
5, spunbond nonwovens
Spunbonded nonwoven fabric in the polymer has been extruded, stretched to form a continuous filament, the filament laying into a web, the web and then through the self-adhesive, thermal bonding, chemical bonding or mechanical reinforcement methods, so that web into a nonwoven fabric.
6, meltblown nonwoven
Meltblown nonwoven process: the polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- into the network --- reinforcement into cloth.
7, acupuncture nonwovens
Acupuncture non-woven fabric is a dry non-woven, non-woven fabric is the use of acupuncture needles puncture role fluffy fiber mesh reinforcement into cloth.
8, stitch non-woven fabric
Stitch non-woven fabric is a dry non-woven fabric, stitch using warp coil structure of the fiber network, yarn layer, non-woven material (such as plastic sheets, plastic thin metal foils, etc.) or a combination thereof body reinforcement, to produce non-woven fabrics.
Depending on the use of product, can be divided into:
⒈ woven bags series: Non-woven bags, woven bags, non-woven shopping bags.
⒉ non-woven bag series: non-woven paper bags, reusable shopping bags, packaging bags, non-woven bag.
⒊ series of non-woven products: non-woven storage box, storage box non-woven, non-woven suit sets - woven suit sets.
⒋ jewelry bag series: gift bags Drawstring bags jewelry bags flannel bags, perfume, jewelry, bags pencil bags.
⒌ aprons series: advertising aprons, polyester aprons, cotton aprons, PVC aprons, aprons linked network
