摘要： Aqueous suspensions of polyolefin fibrids are prepared. To avoid foam formation and improve fiberbonding, small amounts of anionic agents are added to the suspensions. The suspensions are suitable for the manufacture of paper-like or textile-like web structures distinguished by very good fiber bonding and good initial wet strength.

摘要： An improved process of manufacturing fibers by the technique of forming a mixture of polymer, solvent for such polymer and, optionally, water or other flashing aids, at a temperature (flash temperature) which is high enough to bring the polymer to a plastic state and which will permit substantially complete vaporization of the solvent when the mixture is flashed, flashing the mixture into a flash zone to produce a fibrous product and subsequently refining the fibrous product characterized in that the fibrous product is first cooled prior to passing it through a primary refining zone. The primary refining is effected under conditions that impart a vigorous fibrillating action to the fibrous product and provides a pulp having a drainage factor in excess of 1.0 seconds/gram.

摘要： A composition for short cut, synthetic polymeric staple fibers that are used in a wet lay application for the production of nonwovens is disclosed and claimed herein along with a fiber having the finish thereon and the process for dispersing the fiber in an aqueous medium. Synthetic polymeric filaments are cut into staple lengths, generally in a range of from about 1/4 to about 3 inches in length, and are dispersed in an aqueous medium in conjunction with a composition that includes as an essential ingredient, an ethoxylated primary emulsifier that contains at least five moles of ethylene oxide, and exhibits a surface tension of at least 30 dynes per centimeter in a 0.10 weight percent aqueous solution at 25 degrees Centigrade plus or minus 2 degrees Centigrade. Optionally a lubricant may be added to the finish composition to improve processability of the fiber during manufacture. The lubricant should be compatible with the primary emulsifier. A secondary emulsifier may also be added to emulsify the lubricant, and may additionally assist in dispersing the fiber. The composition may be added to the fiber during the manufacture of same or may be added to the aqueous medium. A preferred composition for addition to the fiber at the time of manufacture includes 50 parts of an ethoxylated castor oil, 25 parts of an ethoxylated sorbitol hexoleate and 25 parts of n-octyl, n-decyl adipate. The composition should further be characterized by a low foaming propensity and as not adversely affecting bondability of the fibers.

摘要： Synthetic wood pulp characterized by the presence of polyolefin fibrids having both film and fiber morphology is disclosed as being useful for the production of paper-like films. Further disclosed is a technique whereby this morphology may be preserved by transferring such fibrids from the refining dispersant into a preservative medium. After again being refined in the preservative medium, the fibrids can be formed directly into paper-like substrate products. More usually, however, they are first dispersed in water to facilitate this casting.
