Most fibers are flammable, but there are a few that are not, or are even flame-resistant, such as fiberglass.
Chlorinated fiber is one of them, also known as polyvinyl chloride fiber, commonly used to make flame-retardant materials.
Because of its good heat retention, heat resistance, and lightweight characteristics, it is suitable for making work clothes for wet environments and outdoor workers.
However, this fiber cannot withstand ironing, does not absorb moisture, has poor static properties, and is difficult to dye industrially, so in recent years, its application in the textile field has become rare.
Therefore, besides some specialized work clothing, very few people wear clothes made of chlorinated fiber.
Regarding Wang Zihan's disappearance and murder, statistically speaking, it is more likely that someone from the surrounding Natural Villages committed the crime.
