A standard PSF production line has strong product compatibility and can produce a variety of mainstream polyester staple fiber to meet the diversified demands of downstream industries. Many new factory owners only know that the equipment is used for fiber production, but do not understand the specific product range. Mastering the producible fiber types and their characteristics can help enterprises formulate product plans reasonably and expand market business.

Solid polyester staple fiber is the most traditional and widely used product of standard PSF production line. Its internal structure is compact and uniform, with high tensile strength, good wear resistance and stable chemical properties. By adjusting the spinning and cutting parameters of the production line, solid fiber with different denier and cut length can be produced. Low denier solid fiber is soft and fine, mainly used for clothing fabrics and yarn spinning. High denier solid fiber has stronger hardness and bearing capacity, suitable for industrial textiles, sewing threads and carpet production. The production process of solid fiber is mature and stable, with low defective product rate. It is the basic product for most chemical fiber factories to maintain daily operation and stable income.

By adjusting the structure of spinning components, standard PSF production line can produce hollow polyester staple fiber. The hollow cavity inside the fiber makes the product lightweight, fluffy and excellent in heat preservation performance. This type of fiber has good resilience and will not collapse after long term compression, so it is widely used as filling materials. Common application scenarios include pillows, cushions, quilts, sleeping bags and winter clothing. In the production process of hollow fiber, the production line needs to keep more stable spinning air pressure and temperature. Professional parameter debugging can ensure the hollow rate of each fiber is uniform and avoid partial solid defects. Hollow fiber has high market demand in home textile and apparel industries, which is an important profit product for chemical fiber enterprises.

After simple parameter adjustment and auxiliary material adding, standard PSF production line can also produce various functional modified polyester staple fiber, such as low melting fiber, colored fiber and high tenacity fiber. Low melting fiber has low melting point and is often used for composite fiber and non woven fabric production. Colored fiber adds color masterbatch in the spinning stage, eliminating the later dyeing process and reducing production pollution. High tenacity fiber optimizes the drawing process of the production line, with far higher tensile strength than ordinary fiber, applied to high strength industrial fabrics and filter materials. These functional fibers have higher added value and targeted customer groups. Making full use of the production line to develop functional products can help enterprises get rid of homogeneous competition.
