Seaweed Fiber
Seaweed fiber is a type of plant fiber derived from the ocean, breaking away from traditional methods of obtaining textile materials from land resources. This opens up new possibilities for humans to source materials from the sea in the textile industry, thus earning it the title of "the third fiber". Seaweed fiber uses natural kelp and seaweed organisms as raw materials. Utilizing high-tech low-temperature extraction technology with inert gases, it extracts polysaccharides and various vitamins from kelp and seaweeds. The marine polysaccharides are dissolved in a co-solvent, then degassed and filtered before being extruded through spinneret holes into a coagulation bath, followed by stretching, washing, drying, and crimping processes.
Functional Characteristics:
Skin-friendly Comfort without Dryness
Transforming green seaweed into silky white fibers, the surface is smooth and feels soft to the touch. Seaweed fibers contain hydrophilic groups that provide excellent moisture absorption and retention capabilities. With numerous micropores present within the fibers, they exhibit good water absorption and retention properties, capable of absorbing up to 20 times their own weight in water. Their regain rate exceeds that of cotton, offering superior comfort comparable to cashmere and silk, significantly enhancing the comfort of wearing clothes.
Example Application: Made into thermal underwear, it offers both comfort and warmth while effectively alleviating skin peeling caused by dryness during autumn and winter.

Natural, Eco-friendly, and Renewable
Seaweed fiber is highly environmentally friendly, sourced from abundant brown algae, produced in a zero-pollution water system, and naturally degradable with renewable sources. No hard-to-decompose organic solvents are added during production, ensuring pollution-free production processes and products. Discarded seaweed fibers decompose naturally in the environment without polluting the soil. Throughout its lifecycle, seaweed fiber maintains a green and healthy profile, being kind to the environment.
Example Application: Used in making eco-friendly shopping bags, face towels, makeup remover pads, etc., it is harmless to humans and does not pollute the environment after use.

Antibacterial and Mold-resistant for Better Health
Its strong antibacterial property is another highlight of seaweed fiber, inhibiting various bacteria such as E. coli, Staphylococcus aureus, and Candida albicans. Even after 50 washes, its antibacterial effectiveness remains above 90%. When made into fabric, it acts like an invisible armor, keeping bacteria at bay!
Example Application: Ideal for baby clothing, not only does it resist bacteria and mold but also takes care of the baby's delicate skin without worrying about ingestion of bacteria from biting clothes.

Eliminates Odors to Avoid Embarrassment
Sweat, a watery substance secreted by sweat glands in the skin, is odorless on its own. However, when it encounters bacteria on the skin, it starts to decompose proteins and fats in the sweat, leading to body odor. Seaweed fiber effectively resists bacterial growth, reducing the decomposition of sweat substances, thereby lowering or eliminating odors.
Example Application: Suitable for sportswear to reduce post-exercise sweat smell; also great for socks to minimize foot odor and avoid embarrassment.

Natural Fire Retardant for Added Safety
With a Limiting Oxygen Index (LOI) of ≥45%, seaweed fiber self-extinguishes when removed from fire in the air, producing no smoke, toxic gases, or molten drips. When exposed to flame, only the area in contact with the flame turns black without catching fire due to its carbonization reaction under high temperatures. Without adding any flame retardants, seaweed fiber exhibits excellent flame-retardant performance, making it an ideal inherently flame-retardant biological fiber.
Example Application: Perfect for home furnishings like curtains and carpets, it can effectively prevent fires and protect against harmful smoke inhalation.

Far Infrared and Negative Ions
Seaweed fiber possesses a far-infrared energy emission layer that resonates with human blood, promoting intramolecular vibrations and enhancing physiological functions. In a water-rich natural environment, it generates many negative ions, which can boost metabolism and improve health.
Example Application: Ideal for making sports shapewear that not only ensures comfort and health but also promotes a healthier and more toned physique.

Eliminates Static Electricity for Health
Many people may not know that seaweed fiber also has anti-static properties. Static electricity attracts dust laden with various viruses, bacteria, and harmful substances, posing risks to human health. Severe static electricity can cause skin rashes, irritability, dizziness, chest tightness, nasal discomfort, and even trigger bronchitis, asthma, and arrhythmia. Seaweed fiber can quickly eliminate static electricity generated by friction, making wear safer.
Example Application: Suitable for wool sweaters, blending seaweed fiber with cashmere can effectively alleviate static electricity during putting on and taking off.

Forms Gel Upon Contact with Blood for Pain Relief
When seaweed fiber comes into contact with blood, it forms a gel. Upon interaction with tissue exudate, the fiber swells significantly, retaining large amounts of exudate within its gel structure. The "gel blockage" nature of seaweed fiber greatly reduces the spread of wound exudates and their soaking effect on healthy tissues.
Example Application: Ideal for high-end medical dressings, for burn patients, seaweed fiber dressings maintain wound moisture, preventing dryness and significantly reducing the pain during dressing changes.
