How to improve the performance of non-woven fabrics through materials

At present, the application of non-woven fabrics has spread to all aspects of daily life and industrial production, so different properties are required to meet the requirements of market and industrial applications. In addition to materials, equipment and processes, the selection and use of various additives can also give non-woven fabrics more powerful characteristics and develop high-standard materials and products. Let me take you to see what black technologies are applied to non-woven fabrics.

New custom material from Americhem

Americhem has recently developed a new version of its mBrace softening additive for the nonwovens market. This is in addition to the original mBrace softness additive, allowing nonwoven manufacturers to achieve the desired softness by reducing the coefficient of friction or slippage. The new version currently in development gives the feel of cotton textiles. The thermal stability of this product helps manufacturers produce softer-touch materials without compromising other properties. At the same time, the product can be customized according to the specific requirements of the manufacturer, allowing the softness level to be set, and the usage rate is also more flexible. This helps users ensure optimum softness of the product while eliminating any effects of processing.

AGC develops finish for medical nonwovens

Medical products such as surgical gowns, masks, drapes and packaging must be able to repel liquids, oils and alcohol and be quickly removed in the wash stains. These properties are achieved by coating the nonwoven fabric with a water repellent oil prior to manufacture into garments. However, water repellants have had issues with their durability, as they have the potential to break down to form perfluorooctanoic acid (PFOA). To solve this problem, AGC Chemicals Americas developed AsahiGuardAG-E600, a high-performance, PFOA-free water repellent with better environmental performance and biocompatibility characteristics.

BASF launches water-based acrylic adhesive

BASF has launched a new water-based acrylic adhesive with Acronal 2434 for nonwovens with high thermal stability requirements . Acronal waterborne acrylic and styrene acrylic dispersions are used as adhesives in high quality architectural coatings, adhesives, structural and fiber bonding applications. Acronal redispersible powders act as co-binders in dry mix mortars and improve their properties in a wide range of construction applications.

Eastman Microfibers Enable Product Diversity

Eastman has developed Cyphrex Microfibers to meet the various performance needs of increasingly demanding nonwoven applications , especially those manufacturers of wetlaid nonwovens and specialty papers, who can benefit from improved strength, uniformity 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.

Exxon expands polymer segment

Exxon Brother-in-law Chemical has withdrawn from new low-viscosity Vistamaxx high-performance polymers for hygienic and assembly hotmelt applications thing.

Vistamax performance polymers enable companies to develop innovative solutions to improve product performance and production efficiency. It also has potential sustainability benefits by thinning packaging film, reducing material usage, and reducing rigid packaging thickness to increase product strength to avoid damage or waste. At the same time, he also achieved lower processing temperatures, thereby reducing energy consumption.

Omnova provides binders, finishes

For nonwovens, many factors affect fiber selection, fabric forming, and wire-bonding processes, including process efficiency, product performance, application requirements , consumer demand and usage costs. Omnova's polymer recombination and finishing/surface treatments provide greater flexibility at the moment of decision making for these important processes. For the volatile raw materials currently used, nonwoven manufacturers are looking to use flexible combinations of different fibers and polymers. In spunlace wipes, the raw material mix usually consists of 50% absorbent fibers (polyester or polypropylene), depending on the price of raw materials, and currently, the percentage of viscose is reduced in rain wipe products , which negatively affects absorbency and softness.

In addition, OMNOVA's anti-aging agents and elastomer modifiers are used in the rubber component of elastic waistbands and other stretchable materials to impart elasticity and anti-aging properties to the product.
