Hollow fibres


Hollow fibres

Hollow fibres is a word used on a certain Polyester hollow fibre, first introduced to the market in 1980. The cross-section of this fibre has a tubular form that contains one or more holes and gives the following advantages over solid fibres more resilience/recovery:

  • higher heat insulation
  • better cover
  • more bulky and fluffy
  • lighter in weight
  • higher absorption of water and perspiration.

Nowadays hollow fibers are being produced with various geometries such as rounded, trilobal, triangular and squared. Hollow fibers trap air, providing loft insulation characteristics better than solid fibers, and when used in carpet show less soil and dirt. Hollow polypropylene microfibes are used because of their high breathability, light weight, and softness. These fibres that are used for *underwear are highly elastic and have perfect temperature control and thermal isolation. Their seamless construction ensures superb comfort next to the skin with excellent moisture. Hollow fibres are also used in different domestic, industrial and medical fields for reverse osmosis, hemodialysis, microfiltration, water cleaning systems, pervaporation, gas separation, bedding fabrics such as sheets and cushions, carpets and garments. Application of hollow fibers results in lower extensibility and lower tensile and compressional resilience, but higher bending and shear stiffness and hysteresis. They have a pleasant handle, good water vapour transmission, high thermal isolation and resistance, lower fabric thickness and considerably lower pilling extent. The difference between the spinning processes of hollow fibers and round fibers is due to an additional dimensional variable (inner radius) which is mainly caused by the shape of the spinneret.
