Three-dimensional crimped fiber is called a spiral three-dimensional crimped hollow polyester fiberPolyester is the product name of China, and the countries in the world are different. 

Polyester's wrinkle resistance and heat resistance are superior to other fibers, and its UV resistance and impact resistance are better. 

However, there is a feeling of sultry when used. The production of hollow fiber has made a huge leap in the quality of polyester fibers, and one of the shortcomings of polyester has been thoroughly improved.

The three-dimensional crimp fiber is a good option as the filling materials of home textiles, such as pillows, cushions, and sofa. The specific requirements are as following:

A. Fiber length requirements: In general, the fiber lengths includes 7D, 12D, and 15D, among which the lower D number indicates longer fiber length, finer fiber fineness, as well as better warmth-keeping ability, fluffiness, and thickness. Fibers of 7D or less are the best options for filling materials.

B. Fiber shape requirements: In general, there are zigzag-shaped and spiral-shaped fibers. Among these two, the spiral-shaped fibers are better due to its higher saturation force and elasticity, more space between fibers, as well as better warmth-keeping ability and fluffiness.

C. Fiber structure requirements: In general, there are three types of fiber structures: regular structure, single-hole structure, and porous structure. If the structure of a fiber contains a single-space with a certain length, the fiber is called hollow fiber. On the other hand, the porous structure contains four to seven spaces.  Due to different structures, filling fiber are different in its appearance and texture. Their warmth-keeping ability, fluffiness, and elasticity also vary
