In a new development of a series of non-woven technologies, Dow Chemical Company developed ultra-low formaldehyde adhesives for non-woven products in one-time non-woven and multi-use non-woven production processes.

The original waterborne acrylate adhesives 110, 210, 230 and other products have been used in low formaldehyde products such as wipes, baby and adult diapers, medical mats, medical packaging, curtains, gowns and masks.
However, the adhesive is designed to withstand high humidity, fast penetration and soft hand. Its textile fiber raw materials, intermediate components and end products are in full compliance with the "Environmental Textile 100 Standards".
John Hague, manager of the company's Europe, Middle East and Africa technical services and development department, said: "We are very pleased to make this breakthrough. Companies can use this series of adhesives to make formaldehyde-free nonwovens, and with Bundled with cross-materials, completely eliminate formaldehyde and non-woven products."
At the recent International Nonwovens Exhibition (INDEX11), the company unveiled its newly developed nonwovens, a polyethylene-based fiber-grade resin, Aspun. For single- and bi-component fiber applications, the product offers excellent softness, drape and woven properties, allowing manufacturers to have longer operating times while changing the gap between dyes.
According to Dow, Aspun resin has good adhesion to polyethylene and polypropylene films. When combined with polypropylene homopolymer (HPP), it can improve the tensile properties of high elastic diaper.
In addition, the resin can be combined with polyethylene terephthalate (PET) or polypropylene under the action of a core absorbent to form a two-component binder fiber. In this form, the resin provides excellent liquid handling and reduces the thickness of the nonwoven cellulose.
At the show, Dow Showcased their soft touch polypropylene (PP) resins for the production of single-part resins for single-component spunbond nonwoven fibers.
The first product of this material is DC543 polypropylene resin, which has been designed as an absorbent hygiene product and a medical nonwoven fiber material. According to Dow, the new resin is soft, feels good and reduces noise. This soft-touch polypropylene resin has a low bonding temperature and a wide range of bonding, thus increasing the efficiency and flexibility of processing nonwovens.
The product has been carefully designed to be as stretchable as polypropylene, and at the end it forms a wear-resistant nonwoven with low lint and low fluff. The resin can be recycled through the woven mesh and then converted into a mainstream product.
