Synthetic Fibers
made from small simple molecules and raw materials
Types of Synthetic Fibers
Nylon, Polyester, Olefin and Acrylic
Common Properties of Synthetic Fibers
� Heat sensitive
� Chemically resistant
� Pilling
� Static electricity
� Oleophilic
� Hydrophobic
Slick
� Strong & Resilient
� Resistant to most common fiber degragants
� Wide variation in flame resistance
� Low density
� Non-biodegradable
Common Manufacturing Processes
� Melt spun
- Used for most synthetics
� Drawn
- To develop strength, pliability, toughness, and elasticity properties
� Heat set to stabilize yarns or fabrics
Identification
Solubility Test
Common Fiber Modifications
� Fiber shape and size
- Melt spun fibers easy to alter
- Nanofibers/nanotubes
� Low pilling fibers
- Reduce flex life by reducing molecular weight slightly
High Tenacity Fibers
- Drawing, chemical modifications, or combination
� Low elongation fibers
- Used in blends
Nylon Production

Nylon Physical Structure
Wide variety including multifilament, monofilament, staple, and tow in a wide range of deniers and shapes and as partially drawn or completely finished filaments
Nylon Aesthetic
1. Produces sheer and durable fabric
2. Poor cover
3. Hand, texture, and luster can be controlled for hand use
4. High tenacity
5. Good breaking elongation
Nylon Comfort
- Smooth & "silky" feel
- Low density
- Low absorbency
- Static prone
