Comfort properties of fibre

 Chemical & physical properties of fibre & fibre content, in the yarn affect the behavior of the fabric. Cost, quality, care & comfort are the consideration of a buyer before purchasing clothing.

  Natural fibres are generally considered comfortable due to their better absorbency, heat isolation, handle, luster etc. property. 

 Man-made fibres have high strength, durability, dimensional stability, abrasion resistance, good resistance against heat loss, providing warmth, bulkiness, soft feeling, less moisture absorbency etc. 

  Although man-made fibres are less comfortable, considering their low cost and other good properties , textile producers are using them in apparel products. 

Cotton:

  Cotton is naturally comfortable due to their inherent properties such as hollow fibre, soft, cool, absorbent, breathable etc. 

 Cotton can hold water up to 27 times of its own weight. 

 Since cotton fibre wrinkles, mixing with synthetic fibre e.g. polyester improves the situation. 

Wool: 

 Wool is a natural hair fibre with senses of warmth.

  Excellent property of comfort due to higher hygroscopicity. 

 It can absorp moisture upto 30 times than their own weight. 

 Have natural crimp which creates air pocket hence higher resiliency & thermal resistance property. 

 Good crease recovery property. 

 Highly breathable, hence suitable for breathable fabric and clothing production. 

 Most suitable for cold environment

 Have good natural flame retardency property also. 

Silk: 

 Natural protein fibre with excellent luster, light weight, good moisture absorbency, good strength & elegance. 

 Silk clothes are expensive, versatile, washable & comfortable for good summer clothes.

 Micro-fibre: 

 Fibre fineness less than or equal to 1 decitex are called microfiber.

  Acrylic, viscose, polypropylene, polyester, nylon etc. fibres are produced as microfiber. 

 Micro-fibre shows remarkable properties like softness, luster, handle, good drapability, bulkiness. 

 They are shrink resistant, washable, dry-cleanable, non-electrostatic and non

allergic. 

  They insulate well against wind, rain & cold. 

Hollow fibre: 

 The tubular x-sectional fibres with one or more holes are called hollow fibre. 

  The hollow fibres have following properties which are thought more advantageous than solid fibres.  More resiliency, more bulky & better cover (cover factor high). 

 Higher heat insulation, light weight, higher absorbency of perspiration/water. 

 Used for underwear due to higher breathability, comfortability, lightweight & softness. 

 It is also used for reverse osmosis, hemodialysis, micro-filtration, water cleaning system & gas separation.
