Hollow fibres

Hollow fibre 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.


Advantages

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

Uses in many applications

Nowadays, hollow fibres produce various geometries such as rounded, trilobal, triangular and squared. Hollow fibre trap air, providing loft insulation characteristics better than the solid tread, and when used in carpet show less soil and dirt. Hollow polypropylene microfibes because of their high breathability, lightweight, and softness. The fibres used in underwear because the elastic and have perfect temperature control and thermal isolation.

Their seamless construction ensures superb comfort next to the skin with excellent moisture. Hollow fibres used across industrial and medical fields. For example, reverse osmosis, hemodialysis, microfiltration, water cleaning systems, bedding fabrics, carpets and garments. Hollow fibres advantages include 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 fibre and round is due to an additional dimensional variable (inner radius) which is mainly caused by the shape of the spinneret
