Strength: Nylon filament yarn is very suitable for the manufacture of a wide range of apparels because of its high strength and smoothness. Moreover, the strength of nylon filament yarn doesn’t diminish with life. It is one of the lightest textile fibres and also one of the strongest (strength to weight ratio of nylon filament yarn is high). Nylon filament yarn is added at the points of wear such as knees, seats of jeans and toes, and heel of socks. Nylon has excellent abrasion resistance properties.
Elasticity: Nylon filament yarn has good elasticity which makes it very suitable for apparel manufacturing. Excellent elasticity means fabrics made of nylon filament yarn can retain their original shape without wrinkles or creases. The high elongation and excellent elastic recovery of nylon contributes to the outstanding performance in hosiery. Nylon hosiery recovers its original shape at knees and ankles instead of bagging.
Resilience: Nylon fabrics have excellent resilience. Nylon fabrics retain their smooth appearance and the wrinkles created as a result of daily activities can be removed easily.
Drapability: Fabrics produced from nylon filament yarn have excellent draping qualities. The drape of the fabrics made from nylon can be modified depending on the yarn size. The lightweight sheer fabrics of nylon nightgowns have high-draping quality. The medium-weight dress fabrics can be draped beautifully to enhance the aesthetic appeal.
Shrinkage: Fabrics produced from nylon filament yarn retain their shape and appearance even after washing. It has good stability and does not shrink.
Effect of heat: Effect of heat: Apparels produced from nylon filament yarn can be ironed at low temperatures and do not require high temperature for ironing purposes.
Effect of light: Polyamide fabrics have low resistance to sun light. They are not suitable for curtains or draperies as it gets weakened through exposure to sun light.
Resistance to mildew: Nylon fabrics have absolute resistance to development of mildew. Nylon filament yarn cannot be easily degraded by micro-organisms which ensures enhanced durability.
Resistance to insects: Nylon is resistant to moths and fungi.
Resistance to perspiration: Nylon 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: Nylon filament yarn can be easily dyed with a wide range of dyes. The dyed fabrics retain their colour for a long time and have good resistance to fading. Using the same acid dyes that are commonly used on wool and other animal fibres, vibrant and soothing hues can be obtained. Nylon filament yarn provides an opportunity to produce a comprehensive range of apparels with vivid colors.
Heat conductivity: The heat conductivity of the nylon filament yarn varies depending upon the fabric construction, the type of nylon (staple / filament) used in the construction, etc. For instance, filament nylon used in 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 is prevented from passing through the fabric construction, which makes the wearer feel very warm. The fabrics are ideal for winter apparel, such as wind-breakers, but unsuitable for summer garments. On the other hand, the fabrics with open construction permits air circulation which makes the wearer feel cool. Nylon filament yarn can be used to manufacture wide range of apparels for different seasons by varying fabric construction.
Absorbency: Nylon filament yarns have less absorbency. As a result, water remains on the surface of the fabrics and runs off quickly which results in the fabrics drying in a short time. This property makes nylon fabrics suitable for raincoats and shower curtains.
Cleanliness and washability: Nylon fabrics are easy care garments. Nylon fabrics are smooth, non-absorbent and also dry quickly. Dirt doesn’t cling to this smooth fibre. It can be washed easily or can be even cleaned using a damp cloth. Garments made from nylon filament yarn retain their appearance and shape even after washing.
Effect of bleaches: Nylon fabrics are white and generally do not require bleaching. Nylon fabrics which pick up colour or develop greying should be bleached with oxidising bleaches such as hydrogen peroxide
