How to Antistatic Composite Spinning Fibers
source：www.artisanleather.com.cn | Release time：2025-09-161、 The "core sheath" structure comes with anti-static properties (structural type)
This is the most mainstream anti-static method for composite spun fibers, which involves spinning the "conductive component" and "base fiber" into a "core-shell" composite structure:
Structural features: The core layer is made of conductive materials such as carbon fiber, metal wire, and conductive polymers, while the sheath layer is made of conventional fibers such as polyester and nylon; Or the sheath layer is doped with conductive particles, and the core layer is made of ordinary fibers.
Anti static principle: The conductive core/sheath layer forms a "charge channel", allowing static electricity generated on the fiber surface to quickly dissipate through the channel (rather than accumulate), avoiding static electricity from adsorbing dust or generating sparks.
Applicable scenarios: Products that require long-term anti-static and water-resistant washing, such as industrial dust-proof clothing, electronic factory work clothes, and carpet fibers.
2、 Blended with conductive components (modified type)
Before spinning, mix "conductive additives" into the raw materials of composite spinning to integrate the anti-static properties into the fibers themselves:
Common additives: carbon black, graphene, metal oxides (such as tin dioxide, zinc oxide), anti-static polymers (such as polyether esters).
Anti static principle: Additives form a "conductive network" inside the fiber, and charges can be quickly transferred through the network. At the same time, some additives can improve the fiber's moisture absorption (indirectly reducing static electricity, as water molecules can conduct electricity).
Advantages: Long lasting anti-static effect, will not fall off due to washing or friction, suitable for close fitting clothing (such as underwear, sportswear) and home textile fabrics.
3、 Surface treatment assistance (supplementary type)
If the anti-static properties of composite spun fibers are insufficient, they can be reinforced through post-treatment, which is suitable for cost sensitive scenarios:
Common processes: spraying anti-static agents (such as cationic surfactants), dipping and rolling conductive coatings (such as nano silver coatings).
Antistatic principle: A conductive film is formed on the surface to directly guide charges; Or anti-static agents absorb moisture from the air and form a "water film conductive layer" on the surface of the fibers.
Attention: The effect is prone to fading with washing and friction, making it more suitable for short-term use of products such as composite fibers for packaging and disposable protective equipment.
