Our company produces hollow staple fibers with spiral three-dimensional curls. This spiral curl not only has an arc waveform along the parallel direction of the fiber knot, but also revolves 360 degrees around the fiber axis, allowing the fibers to occupy three dimensional of space.

It is precisely this "permanent" spiral curl that gives our products the characteristics of high fluffiness, high porosity (with a porosity of over 40%), and high resilience. In addition, hollow conjugated fibers provide excellent warmth retention and hydrophobicity, with a soft and smooth feel, light weight, hygiene, no harmful substance retention and diffusion, corrosion resistance, and no insect or mold damage, which many natural fibers do not possess.
