How to give non-woven more powerful performance(1)

Nonwovens have a wide range of applications, covering all aspects of daily life and industrial production, and therefore require different properties to meet market and industry application requirements. In addition to materials, equipment and processes, the choice of additives to use also gives non-woven fabrics more robust properties and develops highly aggressive materials and end products. Here let me take everyone to look at what applies to non-woven black technology.

Omerkey was founded in 1941 and was initially established as a leading manufacturer of fillers and additives for the rubber industry. Since 1959 Color Masterbatch has been produced. Up to this point, Americhem Omerkey has provided solutions ranging from home to merchandise display racks. Currently, it is one of the largest manufacturers of custom masterbatches in the world.

Americhem Omerkey recently developed a new version of the mBrace ™ softening additive in the nonwovens market. This is in addition to the initial mBrace ™ softening additive, which provides nonwovens manufacturers with the desired softness by reducing their coefficient of friction or slip. The new version currently under development gives the feel of cotton textiles. The thermal stability of the product helps manufacturers to make softer, haptic materials without affecting other properties. At the same time, according to the manufacturer's specific requirements for product customization, allowing to set the soft level, the use of more flexible. This helps the user ensure the best softness of the product while eliminating any impact of the process.

Both mBrace ™ technology product groups can be granulated together with other additives and masterbatches to form a one-piece polymer product.

Americhem Omer Kay offers nonwovens manufacturers a complete range of tailor-made solutions, including new color masterbatches, and the color palette of more and more brands and products becomes critical. Omerkey offers manufacturers the ability to add custom colors to their products. These custom colors can also be combined with one or more additives to create multi-attribute masterbatches for dose and inventory control.

Americhem uses its outdoor product expertise to produce nDuramax® UV stabilizer masterbatches that block the detrimental effects of natural light on synthetic fibers and packaging applications to extend the life of nonwovens for any outdoor nonwoven Cloth applications are crucial.

Medical products such as gowns, masks, drapes and packagings must be able to repel liquids, oils and alcohol and remove stains quickly when laundered. These properties are achieved by coating the nonwoven fabric with a water-resistant oil prior to making the garment. However, water repellents have had problems with sustainability because of their potential to decompose to form perfluorooctanoic acid (PFOA). To address this issue, AGC Chemicals Americas has developed AsahiGuard AG-E600, a high-performance, PFOA-free water repellent with better environmental performance and biocompatibility.

AG-E600 waterproofing agent has been found to be safe and effective for use in non-woven medical products. They come from AGC's patented short-chain C6 polymerization technology, which is non-toxic and does not decompose into PFOA or PFOS. In addition, AG-E600 is free of alkylphenol ethoxylates (APEO) and does not contain longer chain perfluorocarboxylic acids (PFCAs) or their precursors.

The AG-E600 is non-flammable and provides excellent non-wicking / alcohol and water repellency properties for polypropylene nonwovens with good compatibility with additives. Medical products formulated with AG-E600 retain their repellency even after repeated washing.

BASF has introduced a new, non-woven fabric that meets the requirements of high thermal stability using Acronal 2434, an aqueous acrylic adhesive. Acronal waterborne acrylic and styrene acrylic dispersions are used as binders in high quality architectural coatings, adhesives, structural and fiber bonding applications. Acronal dispersible powders act as co-binders in dry-mix mortars and improve their performance for a wide range of construction applications.

Acronal 2434 is a self-crosslinking acrylic dispersion that keeps non-woven materials mechanically stable under high-temperature thermal stress. Adhesives are suitable for non-woven fabrics made of synthetic fibers such as polyester, compatible with other cross-linked systems such as melamine and urea resins. The adhesive is particularly suitable for use in construction and grinding applications.

Eastman has developed Cyphrex ™ microfibers to meet the performance needs of increasingly demanding nonwovens applications, particularly those wet nonwovens and specialty paper manufacturers who can improve their strength, uniformity Benefit from sex and reproducibility. Custom development also involves a variety of potential end uses, including but not limited to filtration, packaging, high durability paper, wallpaper and batteries.

Since its first launch in 2013, Eastman has continued to expand its portfolio of Cyphrex ™ microfiber fabrics by combining the world-class technology with the proprietary microfiber technology that enables microfibers to be of any size, shape, and material These needs and concerns come from external markets spanning the non-woven and specialty paper value chains.

Innovations are needed within the nonwovens industry to drive customers' constant search for new materials that enable them to achieve differentiated performance in their products without major process and / or operational changes.

After launching the Eastman Cyphrex microfibre platform with round-shaped microfibers of different sizes, especially Cyphrex 10001 and Cyphrex 10002 (initially for filtration applications), ongoing conversations with nonwovens industry leaders indicate the need for an alternative to fiberglass The material with high pulp content, known as specialty paper, has the added value.

Cyphrex ™ 10101 is a wet-laid, non-woven, wet-paper polyester microfiber with a fiber count of less than 0.4 denier, flat or ribbon cross-section, nominal width of 18 microns, nominal thickness of 2.5 microns and cut length of 1.5 mm.

Cyphrex ™ 10101 enables the manufacturer to produce exceptionally uniform sheets that are lightweight and remarkably strong. Flat fibers exhibit a novel and consistent cross-section that not only provides non-woven fabric producers with significant functional benefits, but also offers significantly improved processability over other synthetic fibers.

Cyphrex ™ 10101 is easy to integrate into existing wet-laid processes and takes the possibilities of vehicle design to a whole new level. Unlike many other synthetic fibers, Cyphrex ™ microfiber pulp is also compatible with other fiber materials such as cellulose and glass.
