Polyamide 6,6
PA 6,6: properties, applications and benefits in the textile industry
Polyamide is a family of synthetic polymers, the first member of which, polyamide 6,6 (also known as PA 6,6 or nylon 6,6), was synthesized by Wallace Carothers at Du Pont in 1935. Polyamide comes in various types, including polyamide 6 (PA 6) and polyamide 10,10, polyamide 5,6 and polyamide 5,10, and is used in many sectors of the textile industry due to its superior properties compared to other fibers.
The number following the word "polyamide" indicates the number of carbon atoms in the constituent element of the molecule. In addition, polyamide can be processed into yarns with varying amounts of neps, thus changing the transparency and softness of the finished product.
Polyamide 6,6 offers superior abrasion resistance, reduced pilling and greater dimensional stability. This means that garments retain their original shape for longer, contributing to product sustainability through increased durability. Polyamide, including PA 6 and PA 6.6 grades, is available in a variety of finishes, from super-bright to super-matt, and can be used to create fabrics for apparel, furniture and industrial textiles. Its properties make polyamide a reliable and versatile choice for many textile applications.
Polyamide 6.6 properties
- Ultra-lightweight: fabrics made with polyamide are extremely lightweight, improving comfort.
- High dimensional stability: Retains its original shape and size even after many washes.
- High elasticity: Provides great flexibility and tear resistance.
- Quick drying and no ironing required: Polyamide dries quickly and does not require ironing, making it easy to care for.
- Non-toxic and hypoallergenic: Safe for the skin, does not cause allergy or irritation.
- Mold, bacteria and insect resistance: has a remarkable ability to resist mold, bacteria and insect attack, ensuring improved hygiene and durability of fabrics.
- Recyclability of end-of-life garments: polyamide can be recycled to create new products.
