Monofilament and Multifilament:
- Monofilament: A single continuous filament used directly. The thread body is relatively stiff and is often used in scenarios requiring shaping, such as fishing nets and sieves.
- Multifilament: Formed by combining and twisting multiple monofilaments. The thread body is soft and has higher strength, making it the main type for garment sewing and fabric weaving.
Basic Advantages of Filament Structure
The fibers are continuous filaments (with a length of up to several kilometers). After twisting, the formed thread body has a smooth surface and uniform evenness, without the fuzz and joints commonly seen in short-fiber threads. Therefore, it is not easy to pill or break during sewing or weaving, and the finished product has a neater and more delicate appearance.
Inherent Properties of Nylon Material
- High elasticity and resilience: Nylon’s elasticity is close to that of wool; it can fully recover when stretched to 3-6%. The thread made from it is not easy to deform after being stressed, making it suitable for scenarios requiring repeated stretching (such as stretch clothing and sports equipment).
- Excellent wear resistance: Its wear resistance ranks first among all textile fibers—10 times higher than cotton and 20 times higher than wool. Therefore, nylon filament thread is friction-resistant, anti-abrasion, and has a long service life.
- Relatively high strength: The strength changes little in dry or wet conditions, and its toughness is not easily reduced by moisture. It is suitable for use in special environments such as outdoors and underwater.
- Chemical resistance: It has good stability against chemicals such as alkalis and detergents, but it will be damaged if in long-term contact with strong acids, so it should be avoided in strongly corrosive environments.
