About fiberfil:

• Fiberfil refers to Polyester Staple Fibres used as filling for pillows, decorative pillows, cushions, bolsters, quilts & comforters, mattresses, mattress toppers, mattress pads, sleeping bags, furniture cushions, furniture backs, insulated garments and soft toys.
• Traditionally cotton has been used as a filling material in India.
• Though with rapid development in synthetic fibre production technology special synthetic fibres have been developed as an alternative to cotton for filling purpose.

Product characteristics

• Fiberfil is available in deniers ranging from 2 to 20 however the most common types of Fiberfil used for stuffing purpose are 6 D and 15 D.
• The fibres are available in cut lengths of 32mm, 40mm, 44mm, 51mm, 64mm, 76mm, 88mm, 108mm and 128mm.
• However, the normal cut lengths used for filling are 32mm (for blow filling), 51mm and 64mm.
• Fiberfil can be classified based on the method of production, cross section of the staple fibres, type of finishing etc.

Classification of fiberfils:

• Based on Manufacturing Process
  • Virgin PSF
  • Regenerated PSF
• Based on Cross section
  • Hollow
  • Solid
• Based on Finish
  • Siliconised
  • Non siliconised
    
    
• Virgin PSF is manufactured from a combination of Terypthalic Acid (PTA) and Monoethylene Glycol (MEG).
• The regenerated PSF is made by recycling polyester waste such as PET bottles and any other 100% polyester scrap.
• Majority of the Fiberfil produced from recycled waste has solid tubular cross section whereas virgin PSF has a hollow core which gives a higher diameter for the same denier and hence higher bulk, particularly for filling end uses. As a result hollow PSF can give the same support level of recycled fibres with 15-20% less filling quantity.
• Moreover the hollow PSF Fiberfil is more soft and comfortable, does not form lumps, retains bulk and shape after wash and is more durable.
• Siliconised PSF has more bounce than non siliconised type.
• Conjugated Fiberfil is another kind of product available which is a bi component fibre with natural crimp (unlike other fibres which need to be imparted crimps in the manufacturing process).

Fiberfil has the following advantages over cotton as a filling material.

• Better filling and greater softness than cotton and other fibres of equivalent weight. The filling quantity required with Fiberfil is 70-80 % of the filling quantity with cotton
• Moisture and mildew resistance which avoids infestation
• Enhanced air circulation (especially for hollow PSF)
• Better bounce and does not become flat with repeated usage.
• Durability
• Wash ability (hollow PSF retain bulk and shape after wash)
