Fiber adhesion

Nonfood Uses. Native com starch is principally used in nonfood appHcations in mining, adhesives, and paper industries. Pregelatinized starch is chemically unmodified, but it is physically modified. Pregelatinized starches are used to decrease water losses in oil-weU drilling muds, in cold water-dispersable wallpaper pastes, and in papermaking as an internal fiber adhesive.

The interaction of two substrates, the bond strength of adhesives are frequently measured by the peel test [76]. The results can often be related to the reversible work of adhesion. Due to its physical nature such a measurement is impossible to carry out for particulate filled polymers. Even interfacial shear strength widely applied for the characterization of matrix/fiber adhesion cannot be used in particulate filled polymers. Interfacial adhesion of the components is usually deduced indirectly from the mechanical properties of composites with the help of models describing composition dependence. Such models must also take into account interfacial interactions. 

Graft copolymerizations have been often employed in industries of plastics, rubber, fiber, adhesives and so on. In most of these cases the gross polymerization product is subjected to processing without isolating the pure graft copolymer. It is well known that the physical properties of the product are closely related to its superstructure, which in turn is a function of both the content and the chemical structure of the graft copolymer present in the product. Therefore, the characterization of the graft copolymer is also desirable to control the product property. 

This brings new evidence of the surface accumulation of one of the constituents, a property that could lead to a great variety of applications, whenever surface modification is needed, e.g. in films, fibers, adhesives, coatings, varnishes, affinity chromatography etc. 

Adhesion promoters were first used to treat glass fibers and other fdlers before they are incorporated into liquid resin to make composite materials. In the fiber industry, adhesion promoters are also known as finishes. Certain finishes have been specially developed to match a fiber with a resin matrix. Without adhesion promoters, the interfacial resin-glass fiber adhesion is weak, and water can diffuse along the interface with catastrophic results on the end properties of the composite. 

Many film adhesives have a supporting carrier or reinforcement fabric incorporated into the adhesive to improve handling of the film and provide control of bond line thickness. The carriers are usually glass, polyester, or nylon fabrics of knitted, woven, or nonwoven construction. The difficulty with such carriers is that they can provide an effective way of moisture entering the bulk of the adhesive. Moisture can wick along the fiber-adhesive interface. Nylon carriers should especially be reviewed since they have a strong tendency to absorb moisture. 

Acrylic acid is almost exclusively used directly, or after conversion to an ester, as a monomer. Acrylate esters are produced by normal esterification processes. However, in dealing with acrylic acid, acrolein, or acrylates, unusual care must be taken to minimize losses due to polymerization and other side reactions such as additions of water, acids, or alcohols across the reactive double bond. Polyacrylic acids find use in superabsorbers, dispersants, and water treatment. The polyesters are used in surface coatings, textile fibers, adhesives, and various other applications.

Protein produced from solvent-extracted meal has been used as a thickening agent in soups, baby foods, high-protein foods, instimtional meals, and meat products. Groundnut proteins have also been used to manufacture a soft, wool-like, cream-colored fiber, adhesive products such as plywood glue and wettable glue, and for paper coating.

Glass fibers are extensively used by industiy because of their reinforcing effect, and the improvements they produce in thermal properties such as a reduction in thermal expansion and an increase in heat deflection temperature. The most challenging tasks of fiber application include the incorporation process which must be designed to prevent breakage, improve matrix fiber adhesion, prevent fiber corrosion in some environments, and develop proper fiber orientation.

The primary use of liquid petrolatum is as a laxative, a product that loosens the bowels. It also has a number of other applications, such as an additive in foods such as candies, confectionary products, and baked goods as an ingredient in personal care products, such as baby oil creams, hair conditioning lotions, and ointments in many different kinds of pharmaceutical preparations in the production of industrial lubricants as a softening agent in the manufacture of rubber, textiles, fibers, adhesives, and machine parts as dust suppressants and as dehydrating agents for a number of industrial processes.
