Spun-bonded non-woven fabrics and non-woven fabrics is subordinate relationship. Non-woven fabric production technology of manufacturing, there are many, including spun-bonded method is a kind of non-woven fabric production process ( Including spun-bonded, melt-blown, hot rolling method, the water thorn method, is now on the market most are manufactured with the method of spun-bonded non-woven fabric) Dongyang lai chi non-woven non-woven fabric according to the composition, polyester, polypropylene, polyamide, polyurethane, acrylic, etc; Different components have different style of non-woven fabrics. And spun-bonded non-woven, usually refers to the polyester spun-bonded non-woven, pp spun-bonded non-woven fabric; And that was very close to the style of the two kinds of cloth, through the high temperature test can identify. What is spun-bonded non-woven fabric is in polymer has been after extrusion, stretching to form a continuous filament, filament laid into the net, fiber network through self bonding, hot glue, chemical bonding or mechanical reinforcement method, make fabric non-woven fabrics. What is a non-woven non-woven fabric is a kind of nonwoven fabric, it is directly using polymer slice, short fibers or filament fiber by air flow or machine into the net, and then through the water thorn, acupuncture, or hot rolling reinforcing, and then after finishing of woven fabrics. Spun-bonded non-woven technology parameter table of spun-bonded non-woven fabric features: 1, the fabric is made up of continuous filament. 2, good tensile strength. 3, process change is more, can use various reinforcement methods. 4, wide range of filament denier changes. Characteristics of non-woven non-woven fabric has a soft, breathable and plane of the structure of the new type of fiber products, advantage is that do not produce fiber crumbs, strong, durable, soft as silk, is also a kind of reinforced material, but also the feeling of cotton, compared with cotton, non-woven bag, easy forming and cheap. Spun-bonded non-woven products application: 1, polypropylene ( PP) : geotextile, tufted carpet base cloth, coated cloth, and medical materials, use of disposable products coated materials. 2, polyester ( PET) : filtration material, lining material, tufted carpet base cloth, agricultural materials, packaging materials, etc.
