Strength: Polyamide has good tenacity and the strength does not diminish with age. It is one of the lightest textile fibres, but also one of the strongest. It provides tenacity to areas of the garment that are prone to excessive wear and tear like knees, backside of jeans and toes and heels of socks.
Elasticity: Good elasticity makes it highly suitable for use in manufacturing apparel. The excellent elasticity would mean that Polyamide materials return to their original shape without wrinkles or creases. Excellent elasticity contributes to outstanding performance in hosiery garments. Polyamide hosiery garments recover their original shape at knees and ankles instead of bagging
Resilience: Polyamide fabrics have excellent resilience. Polyamide fabrics retain their smooth appearance and the wrinkles from the usual daily activities can be removed easily.
Drapability: The drape of the fabrics made from Polyamide can be varied depending on the yarn size. The lightweight sheer fabrics of Polyamide night gowns have high-draping quality. The medium-weight dress fabrics can be draped beautifully across one’s body.
Shrinkage: Fabrics retain their shape and appearance after washing, have good stability, and do not shrink.
Effect of Heat: Nylon fabrics should always be ironed at low temperatures. Usage of hot iron can result in glazing and sticking of the fabric.
Effect of Light: Polyamide fabrics have low resistance to sun light. They are not suitable for curtains or draperies as it is weakened by the exposure to sun light.
Resistance to Mildew: Fabrics display high degree of resistance to the development of mildew.
Resistance to Insects: Polyamide is resistant to moth and fungi.
Resistance to Perspiration: Polyamide fabrics are resistant to perspiration.
Reaction to Alkalis: Polyamide has excellent resistance to alkalis.
Reaction to Acids: Polyamide is less resilient to the action of strong acids.
Affinity for Dyes: Polyamide can be easily dyed and is compatible with a wide range of dyes.
Heat Conductivity: The heat conductivity of the Polyamide fabrics varies depending upon the fabric construction and the type of Polyamide (staple/filament) used. For instance, the filament Polyamide used in the open construction would be cooler when compared to the same filament used in a closed construction. In a closed or tight construction the air circulation through the fabric is limited. The heat and moisture of the body will not readily pass the fabric construction, which makes the wearer feel warm. Such fabrics are good for winter apparel, such as wind-breakers, but are not suitable for summer garments. On the other hand the fabrics with open construction permit the air circulation which makes the wearer feel comfortable.
Absorbency: Polyamide fabrics have low absorbency. The main advantage of the Polyamides low absorbency attribute is that the water remains on the surface of the fabrics and runs off the smooth fabric and hence dries quickly. This property is extremely useful for raincoats and shower curtains.
Cleanliness and washability: Polyamide fabrics are easy care garments. Polyamide fabrics are smooth, non-absorbent and dry quickly. Dirt doesn’t cling to this smooth fibre.
Effect of Bleaches: The Polyamide fabrics are white and generally do not require bleaching.
