Latex bonding

Olefin fiber is an important material for nonwovens (77). The geotextile market is stiU small, despite expectations that polypropylene is to be the principal fiber in such appHcations. Disposable nonwoven appHcations include hygienic coverstock, sanitary wipes, and medical roU goods. The two competing processes for the coverstock market are thermal-bonded carded staple and spunbond, both of which have displaced latex-bonded polyester because of improved strength, softness, and inertness. [Pg.322]

The earliest of these applications was natural rubber latex bonded paper. This was patented in En and in 1926 and commercially developed in the United States before 1930 to produce products which eSectively replaced leather in applications such as shoe insoles and roidsoles. Latex was... [Pg.302]

Research condncted with turkey feather fibers has focused on producing yams and knit fabrics containing these fibers, as weU as producing latex bonded nonwoven fabrics for use in erosion control materials. [Pg.167]

Based on experience with the production of yam containing turkey fibers, attempts were made to produce nonwoven fabrics with these fibers. Based on the success of initial experiments, air laid and latex bonded nonwoven fabrics containing turkey fibers were produced. Needle-punching was attempted initially, but the fibers were too stiff to entangle effectively. However, it has been reported by MaXim LLC that feather fibers produced today are more flexible than those utilized in this research, and thus needle-punching may be an effective method of bonding these fabrics. ... [Pg.175]

The latex bonding agent should not be used by itself because too much could be absorbed by a porous substrate, leaving a minimal thickness in the glue line. It may also dry too quickly to form an effective bond by the time new concrete is applied. It is best used in the form of a slurry grout. [Pg.808]

The crossHnking resins such as melamine can be used to enhance wet and dry tensile strength, moisture resistance, heat resistance and solvent resistance (dry-clean-ability) of non-woven fabrics. Figure 10-9 illustrates examples of the stiffness improvement of an acrylic latex bonded non-woven sheet as a function of the latex level in the sheet at two different levels of the melamine resin [12]. [Pg.275]
