In recent years, the polyester flannel fabric produced by the polyester flannel fabric factory has become very popular, so what is its nature?
Polyester is generally milky white with mercerizing, matting agent TiO2 must be added before spinning to produce dull products, brighteners are required to produce pure white products, and pigments or dyes must be added to the spinning melt to produce colored yarns.
Surface and cross-sectional shape. The surface of conventional polyester is smooth, and the cross-section is nearly round. If a special-shaped spinneret is used, fibers with special cross-sectional shapes can be made, such as triangular, Y-shaped, hollow, and other special-shaped cross-section filaments.
When polyester is completely amorphous, its density is 1.333g/cm3. When fully crystallized, it is 1.455g/cm3. Generally, polyester has a higher degree of crystallinity, with a density of 1.38~1.40g/cm3, which is similar to wool (1.32g/cm3).
And because of these properties, the home textile fabric factory will also use this as a home fabric. www.dfknit.com
