Dow Chemical Company of the United States successfully developed new non-woven fibers

by:Sunshine     2019-12-18
In a series of new developments in non-woven technology, Dow Chemical Company of the United States has developed ultra-low formaldehyde adhesives for non-woven in the process of one-time injection and multiple use of non-woven production. The original series of waterborne acrylate adhesives 110, 210, 230 and other products have been used in low formaldehyde products, such as wet wipes, baby and adult diapers, medical mats, medical packaging, curtains, masks and masks. However, the adhesive is designed to have strong humidity resistance, fast penetration and soft hand feel. Its textile fiber raw materials, intermediate components and end products all fully comply with the Environmental Protection textile 100 standard. John, manager of the company's technical services and development department in Europe, the Middle East and Africa. Black said:'We are pleased to make this breakthrough. Enterprises can use this series of adhesives to make formaldehyde-free inputs and bind them with cross materials to completely eliminate formaldehyde from inputs. 'At the recent international jewelry exhibition (INDEX11) On the other hand, the company demonstrated its newly developed non-woven sanitary product, which is polyethylene-based fiber grade resin Aspun. In order to meet the application of one-component and two-component fibers, the product can provide excellent softness, drapability and textile performance, allowing manufacturers to have longer operation time during changing the gap of dyes. Dow pointed out that Aspun resin is very viscous to polyethylene and polypropylene films, and is in a homogenizer with polypropylene (HPP) When combined, it can improve the strong tensile property for the formation of high elastic diaper properties. In addition, the resin can be used with polyethylene terephthalate (PET) Or polypropylene is combined into a two-component adhesive fiber under the action of a core absorption force. In this form, this resin provides excellent liquid tube control and reduces the thickness of non-woven cellulose. At this exhibition, Dow showed their soft touch polypropylene (PP) Resin, a single-particle resin used to produce one-component spunbonded non-woven fiber. The first product of this material is DC543 polypropylene resin, which has been designed as absorbent sanitary products and medical non-woven fiber materials. According to Dow, this new resin has high softness, good feel and low noise. This soft-touch polypropylene resin has a lower bonding temperature and a wide bonding range, thus improving the efficiency and flexibility of processing inputs. The product has been carefully designed, its tensile properties can be comparable to polypropylene, and in the end, it forms wear-resistant inputs with low lint loss and low lint rate. The resin can be recycled through the textile mesh and then converted into mainstream products.
