  • Spunlace nonwoven technology knowledge

    Home > News > Technical knowledge

    Product featuresSoft, fluffy, high moisture absorption, there is a certain oil absorption effect,Spunlaced composite technology,Spunlaced composite technology research and development, which not only overcome the limitations of some of the nonwoven products, increased the designs and varieties, greatly broaden the application field of spunlace nonwovens, and promoted the spunlace technique and the whole the development of nonwovens technology and improved. 1: water and wood pulp flow to the network composite technology. Because of the wood pulp prices spunlace is often used for short fiber is much cheaper, hygroscopicity and fluffy pulp and feel very good, so manufactured products are cheaper than full with fiber products, is the price is very competitive, but has a high requirement on the process of filtering system. Products can be used as a wiping cloth 70% (g/m2), diapers and sanitary napkin filling material

    2: the water thorn and long silk spinning viscose fabric composite technology. The method of composite products as spun-bonded nonwoven fabric is Chinese measures strength and short fiber good absorption performance, and the spun-bonded nonwoven fabric uniform, soft water absorption of oil absorption function, and high intensity, can be used as a food packages cloth, decorative cloth and cleaning cloth, etc. 3: composite technology and wet to the water network. Hydraspun technology of typical process Detex company by Detex wet into network technology combining with Unicharm Japanese company registered Soflom spunlace method. Hyderaspun wet strength and flexibility of spunlaced nonwovens is equal to or even more than the traditional dry spunlace nonwovens, and wet spunlaced nonwovens dropping, the seam tensile strength is dry process of spunlaced nonwovens two times, especially in garment field

    British Loughborough university department of mechanical engineering of Memis Acar research proves that glass fiber spunlaced process can processing, production of industrial fabrics, as there is no crimp glass fiber, find it difficult to dry nonwoven technology processing in traditional concepts. Most of the glass fiber nonwovens is generally by acupuncture or wet process, but the American north Carolina state university (NCSN) has been successfully developed glass fiber and polyester blended spunlaced nonwovens. 16 um coarse denier glass fiber diameter, water method is difficult to process, if the fine denier glass fiber with a diameter of 6.5 um mixing, is to improve the strength of spunlaced nonwovens, the different size of glass fiber mixed, fine denier fiber spunlaced, coarse denier fiber to improve the strength of spunlaced nonwovens. If the glass fiber and textile fiber such as polyester mix, can strengthen the water thorn tangles. Glass fiber with low melting point polyester mix, can produce glass local reinforced polyester composite materials. Researchers at the university of the United States Auburm NGSN equipment found water thorn method can produce cloth, geotextile is currently produced by acupuncture and hot rolling process. The researchers found that the change of water pressure and fabric water effect can change the aperture of geotextile. Aperture are the key indicators of geotextile, especially with the sand filter layer, prevent soil movement allows water to pass through. Extend the fabric subjected to water of the time or the increase of water pressure, can improve fabric spunlace tangles effect, and make the fabric narrow aperture. Aperture size can adjust online don't have to stop, so as to improve production speed, other than the geotextile flexible processing technology is simple.
