The lanyard that can be seen everywhere in life, simple but not ordinary, low-key but not credit. And lanyards have many different materials, the next is the introduction of some.
Here is the content list:
Nylon
Viscose
Polyester
Polyamide
Acrylic
Vinylon
Nylon, near the flame that is quickly curled and melted into a white gel, in the flame molten combustion drops and blistering, burning without flame, leaving the flame is difficult to continue to burn, emitting celery smell, after cooling light brown molten material is not easy to grind. The disadvantage of nylon lanyards is water absorption, affecting the dimensional stability and electrical properties, fiber reinforcement can reduce the resin water absorption so that it can work under high temperature and high humidity. Nylon has a very good affinity with glass fiber.
Viscose is a man-made cellulose fiber, spun by the solution method, due to the inconsistent solidification rate of the fiber core layer and the outer layer, forming a skin-care structure (from cross-sectional sections can be seen). Viscose is the most hygroscopic of the common chemical fibers. The lanyard made of this material has good dyeing, good wearing comfort, poor viscose elasticity, strength in wet state, wear resistance is very poor, so viscose is not resistant to washing, poor dimensional stability. Specific gravity, heavy fabric, alkali resistance not acid resistance.
Polyester lanyard is characterized by high strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, acid resistance not alkali resistance, good light resistance (second only to acrylic), exposure to the sun for 1000 hours, the strength to maintain 60-70%, moisture absorption is very poor, dyeing difficulties, the fabric is easy to wash and dry quickly good conformability.
The biggest advantage of nylon is that it is strong and wear-resistant, and it is the best one. Small density, light fabric, good elasticity, fatigue damage resistance, chemical stability is also very good, alkali resistance not acid resistance! The biggest disadvantage is that the sunlight resistance is not good, the lanyard will become yellow after a long time in the sun, strength decline, moisture absorption is also bad, but better than acrylic, polyester.
The internal structure of acrylic is unique in that it has an irregular spiral confirmation, and there is no strict crystallization area, but there is a high order arrangement and a low order arrangement. This structure makes acrylic lanyard has good thermal elasticity (can be processed puffy yarn), acrylic density is small, smaller than wool, fabric warmth is good. The characteristics of acrylic lanyards are good sun and weather resistance (in the first place), poor moisture absorption, and difficult dyeing.
The biggest characteristic of vinylon is moisture absorption, the best synthetic fiber, known as "synthetic cotton". Strength than nylon, polyester poor, chemical stability, does not resist strong acid, alkali resistance. Vinylon lanyard sunlight resistance and weather resistance is also very good, but it is resistant to dry heat and not wet heat (shrinkage) elasticity is the worst, the fabric is easy to wrinkle, dyeing is poor, color is not bright.
