In a series of new developments in non-woven technology, Dow Chemical Company developed ultra-low formaldehyde adhesives for non-woven applications in disposable non-wovens and multi-use nonwovens.
The previously used series of water-based acrylate adhesives 110, 210, 230 have been used in low-formaldehyde products such as wipes, baby and adult diapers, medical pads, medical packaging, curtains, gowns, and masks.
However, the design properties of the adhesive are strong against moisture, fast penetration, and soft hand. Its textile fiber raw materials, intermediate components and end products are in full compliance with the "Environmental Protection Textile 100 Standard."
"We are pleased to have made this breakthrough," said John Haeger, manager of the European, Middle East and African technology services and development department of the company. "We can use this range of adhesives to make non-formaldehyde-free nonwovens." The cross-materials are bundled to completely eliminate formaldehyde and non-woven products."
At the recent International Nonwovens Fair (INDEX11), the company demonstrated its newly developed non-woven hygiene product, which is a polyethylene-based fiber-grade resin Aspun. In order to meet the requirements of single-component and bi-component fibers, this product can provide excellent softness, drape, and woven performance, allowing manufacturers to have longer operating time during changing the dye gap.
Dow company pointed out that Aspun resin and polyethylene, polypropylene film adhesion is very good, when combined with polypropylene homopolymer (HPP), it can improve the strong stretchability for the formation of high elastic diaper performance.
In addition, the resin can be combined with polyethylene terephthalate (PET) or polypropylene under the influence of a core's absorption force as a bicomponent binder fiber. In this form, this resin provides excellent liquid management and reduces the thickness of non-woven cellulose.
At this exhibition, Dow presented their soft-touch polypropylene (PP) resin for the production of single-component spunbond nonwoven fiber single particle resins.
The first product of the material was DC543 polypropylene resin, which has been designed as an absorbent hygienic product and medical non-woven fiber material. According to Dow, the new resin is soft, feels good, and reduces noise. This soft touch polypropylene resin has a lower bonding temperature and a wide range of bonding, thus improving the efficiency and flexibility of processing nonwovens.
The product has been carefully designed, its tensile properties are comparable to those of polypropylene, and in the end it forms a wear-resistant nonwoven with low lint and low fluffing rate. The resin can be recovered through a scrim and converted into a mainstream product.
