Non-Woven Bag Principle
- Sep 04, 2017 -

Non-woven bag is a green product, tough and durable, handsome in appearance, good ventilation, can be reused, can be washed, silk screen advertising, mark, the use of long.

Products are non-woven 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, recyclable and so on. The material is placed in the outdoor 90 days can be natural decomposition, 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.

Principle: non-woven fabric is a non-woven fabric, it is directly using high polymer chips, short fibers or filament through a variety of fiber forming methods and consolidation technology with a soft, breathable and planar structure of the new fiber products. Non-woven bags compared to the advantages of traditional plastic bags: non-woven bags cheap, environmentally friendly and practical, widely used, 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.

Non-woven bags of raw materials are polypropylene, and plastic bags of raw materials is polyethylene, although the two substances similar names, but the chemical structure is very different. 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, a non-woven bags in 90 days can be completely decomposed.

Non-woven fabrics do not need the textile process and made like cloth non-cloth products, also known as non-woven. Because it is only the textile short fiber or filament orientation or random support, the formation of fiber structure, and then use mechanical, thermal or chemical methods can be made to strengthen. Most non-woven bags are made of spunbond nonwovens.

Simply speaking: nonwovens are not woven by a single yarn, knot together, but the fiber directly through the physical method of bonding together, so when you get your clothes in the sticky , It will be found, is not a root of the thread. Nonwovens break through the traditional textile principles, and has a short process, production speed, high yield, low cost, wide use, raw materials and more features.

Laminating non-woven bags, the product using cast way, compound firmly, in the composite process is not viscose, soft to the touch, no plastic feeling, no skin irritation, for disposable medical single, bed sheets, Isolation clothing, protective clothing, shoe covers, and other health care products production; this cloth bag is called Fumo non-woven bags.

Non-woven bags are generally used screen printing process, which is often said that "silk screen", which has been a lot of manufacturers more commonly used printing process. Generally artificial printing, because the printing smell, color is not full easy to fall off, so the emergence of many new non-woven printing methods, where we introduce several mainstream on the market:

Watermark: because of its use of water-based rubber mortar as the printing medium and named in the textile printing more common, also known as printing. When printing the color paste and water-based plastic glue to reconcile. Wash the plate without chemical solvents, can be washed directly with water. Its characteristics are good coloring ability, with strong cover and fastness, washable, basically no smell. Generally used for printing: canvas bag, cotton bag.

Gravure printing: finished products processed in this way are usually called non-woven bags. This process is divided into two steps, that is, the first use of the traditional gravure printing process will be printed on the film, and then use the coating process will be printed on the pattern of film composite in the non-woven fabrics. General large-scale color pattern printing of non-woven bags are used in this process. Its characteristics are beautifully printed, full use of machine production, production cycle is short. In addition the product has excellent waterproof performance, the durability of the finished product than other non-woven bags produced. Film with light and matte two options, matte scrub effect! The product is stylish and generous, durable, full color, pattern realistic, the disadvantage is the price is more expensive.

Thermal transfer: thermal transfer in the printing is a special printing! The method requires an intermediate medium, which is first printed on the thermal transfer film or thermal transfer paper, and then transferred to the nonwoven fabric by heating the transfer apparatus. The medium commonly used in textile printing is a thermal transfer film. Its advantages are: fine print, a rich sense of hierarchy, comparable to the photo. Suitable for small area color image printing. The drawback is that time long prints are easy to fall off and are expensive.
