Hollow Fiber of Natural Warmth

RHF is produced by hollow spinning of general polyester. The hollowness of RHF give it natural heat-retaining properties like cotton that provides natural warmth and lightweight.

Hollow Fiber with Feather Touch

RHS is siliconized after producing by hollow spinning technology. The hollowness of RHS give it natural heat-retaining properties like cotton that provides natural warmth and light weight and the silicone treatment provides feather touch.
Synthetic fibers refer to fibers that are not in nature and are made into human hands. This kind of  fibers have found a very good place in the textile industry by improving some of the specifics or eliminating the defects in natural fibers, as well as lower production costs compared to natural fibers.
In the meantime, polyester fibers among other synthetic fibers, have a better position due to the physical, mechanical and chemical conditions, and replace different types of natural or synthetic fibers in various industries.

Product Characteristics

Hollow fibers in the forms of HRF, HRS, HCF, HCS from 3 deniers to 15 deniers

This fiber has a cross-sectional hollow section, depending on the shape of the holes of the spinneret used in the machine to produce different shapes of fibers.

circular cross-section (O type, semicircle (C type) and triangle).

This product is used because of the high volume of filaments for filling and sleeping goods and doll making with silicon and without silicon. Silicon is used to slip the fibers on each other.


Polyester fibers are used in the manufacture of many products, including clothing, home furnishings, industrial fabrics, filters, tire cord fabrics, and nonwoven fabrics.

Polyester has several advantages over traditional materials such as cotton.

It does not absorb moisture, but does absorb oil; this quality makes polyester the perfect fiber for the application of water, soil, and fire resistant finishes.

Its low absorbency also makes it naturally resistant to stains.

Polyester clothing can be preshrunk in the finishing process, and thereafter the fabric resists shrinking and will not stretch out of shape.

The fabric is easily dyeable and is not damaged by mildew.

Textured polyester fibers are an effective, non-allergenic insulator, so the material can be used for filling pillows, quilting, outerwear, and sleeping bags.
