Polyester chip is generally employed to make containers, such as soft drink bottles; film for multiple uses including food wrap, for example; molded parts for appliances or the automotive industry, for example; and fiber for the textile or industrial uses. Of the many uses for polyester chip, containers and industrial fibers require a high molecular weight chip. Primarily the high molecular weight is obtained by running polyester chip through a solid state polymerizer to increase its molecular weight. In the fiber making art, low molecular weight chip may be used to make textile products. Textile products do not require the high tensile strength and increased physical properties required for industrial fiber uses. Typical industrial fiber uses include seat belts, airbags, tire cord, and other reinforcement for conveyor belts, hoses, and v-belts, for example.
