AGC Develops Repellent for Medical Nonwovens
Medical products like surgical gowns, masks, drapes and packaging must be able to repel fluids, oil and alcohol, and quickly
release stains when laundered. Those properties are achieved by
coating nonwoven fabrics with repelling agents before they are
fabricated into clothing. However, repelling agents have had a
history of sustainability issues because of their potential to break
down forming perfluorooctanoic acid (PFOA). To address this
problem, AGC Chemicals Americas developed AsahiGuard AG-
E600, a high-performance, PFOA-free repellent with improved
environmental and biological profiles.
AG-E600 repelling agents have been found to be safe and effective for use in nonwoven medical products. They are based
on AGC’s patented short-chain C6 polymerization technology,
which is nontoxic and does not break down to form PFOA or Per-fluorooctane sulfonate (PFOS). In addition, AG-E600 is alkylphe-nol ethoxylate (APEO) -free and does not contain longer chain
length perfluorocarboxylic acids (PFCAs) or their precursors.
AG-E600 is nonflammable, provides excellent alcohol/oil repellency and water resistance for polypropylene nonwovens, and
has high compatibility with auxiliary agents. Medical products
formulated with AG-E600 maintain their repelling performance
through repeated washings.
Americhem Provides New Materials for the
Americhem has recently developed a new version of its mBrace
softening additive to the nonwovens market. This is in addition
to the initial group of mBrace softeners, which let manufacturers
achieve their ideal level of softness by reducing the coefficient
of friction, or slip. A new version currently under development
imparts a cottony, textile feel. This product is thermally stable and
helps the manufacturer deliver a soft touch without impacting
other material properties. There is also added flexibility in the
use rate, which can be customized to the manufacturers’ specific
requirements. This allows the user to ensure optimum softness
while eliminating any impact to processing conditions.
Both of the product groups of mBrace technology can be combined with other additives and color in an all-in-one product pelleted product. All of the mBrace products offered in Europe are
compliant with REACH regulations and the products are available in a variety of packaging options.
Americhem offers new custom-made color masterbatches for
nonwovens producers. Increasingly, brand and product colors are
becoming of the utmost importance. Americhem gives producers
the ability to add custom color to their products. These custom
colors can also be combined with one or more additives for ease
of dosing and inventory control. Americhem utilizes its expertise
in outdoor products to produce nDuramax UV stabilizers which
are critical for any outdoor nonwovens application.

BASF Introduces Aqueous Acrylic Binder
With Acronal 2434, BASF has introduced a new aqueous acrylic
binder for nonwovens meeting high thermo-dimensional stability requirements. The binder is particularly suitable for nonwovens that are used for construction and abrasive applications.
The innovative binder complements the comprehensive BASF
product portfolio of binders and resins.
Acronal 2434 is a self-cross-linking acrylic dispersion that
lends nonwovens that are exposed to thermal strain high levels of
mechanical stability. The binder is suitable for nonwovens made
of synthetic fibers such as polyester and is compatible with other
cross-linking systems such as melamine and urea resins. It can
also be applied with regular foulard systems.
“Acronal 2434 is another high-performance binder that we offer
to our customers in the nonwovens industry,” says Jürgen Pfister,
vice president of dispersions for adhesives and fiber bonding
