Melt Additives

Goulston Technologies, Inc. continues its innovative approach to fiber and fabric surface modification by developing polymer (melt) additives that provide unique properties for today’s demanding and sophisticated synthetic fibers and non-wovens markets. These new additives provide specific functionalities that include alcohol repellency, water repellency, hydrophilicity and soft hand. The customer will find that these products are easy to use and give excellence performance.

Polypropylene Hydrophobic and AR

HydRepel™ is a new series of hydrophobic additives that repel fluids with maximum efficiency. The alcohol repellent version gives high AR ratings allowing it to be used in sterile, hospital and white room venues. Other additives are available where water repellency is needed either to resist absorption into or penetration through the substrate. All of the hydrophobic additives can be custom compounded into the required MFI polypropylene resin.

Polypropylene Hydrophilic

Goulston has developed a hydrophilic additive with excellent moisture management properties that can be used in hygienic or non-hygienic applications. Durability teamed with very good absorbency allows this product to be used in all types of non-woven consumer products. Interestingly, the additive lowers the bending modulus of polypropylene which in a spun bond product imparts softness of hand or drape.

Polyropylene Softhand

Goulston’s soft hand additives provide a silk-like hand that provides extreme comfort for direct skin contact. When used in any hygienic and non-hygienic non-woven applications they provide silky softness and drape-ability. These additives can be used in filament applications to provide softness and drape-ability characteristics that had previously been possible only with micro deniers.
