Water soluble fibers refer to fibers that can dissolve in water or slowly hydrolyze into water-soluble molecules or compounds when in contact with water. They are a kind of very valuable functional differential fibers. With the continuous enhancement of people's environmental awareness, the application of non-toxic, pollution-free and hydrolyzable environmentally friendly water soluble fibers has gradually become popular. Alfa Chemistry offers a range of water soluble fiber products to meet your specific needs.
Common Types of Water Soluble Fibers
Some common types of water soluble fibers include:
- Water-soluble polyvinyl alcohol fiber. Water-soluble polyvinyl alcohol (PVA) fiber is the most widely used and produced water-soluble fiber with the characteristics of low cost, hydrolysis and pollution-free. PVA fiber is a fiber processed by stretching, drying and heat treatment of PVA solution under dry heat conditions after spinning. According to the dissolution temperature in water, PVA fiber can be divided into low-temperature water-soluble PVA fiber (0-40 ℃), medium-temperature water-soluble PVA fiber (41-70 ℃) and high-temperature water-soluble PVA fiber (71-100 ℃).
- Alginate fiber. Alginate fiber is derived from seaweed and is known for its excellent water solubility and biocompatibility. Alginate fiber is often used in medical dressings and wound care products due to its ability to absorb moisture and promote healing.
- Carboxymethyl cellulose fiber. Carboxymethyl cellulose (CMC) fiber has high hygroscopicity and is often used in the textile industry to increase the strength and durability of fabrics.
Characteristics
- Hygroscopicity. Water soluble fibers have good hygroscopicity, can absorb sweat and moisture, keep the skin dry, and make the wearer feel dry and comfortable.
- Softness. Water soluble fibers have good softness and elasticity, and are easy to process into various textiles.
- Biodegradability. Water soluble fibers can decompose naturally in a short time, have no pollution to the environment, and meet environmental protection requirements.
- High temperature resistance. Water soluble fibers are resistant to high temperature, not easy to melt and stick, and can be used for processing under high temperature conditions.
- Good printing and dyeing performance. The surface of water soluble fibers is smooth, bright in color, and easy to absorb printing and dyeing agents.
Applications
As a new type of raw material, water soluble fibers are widely used in medicine, textile, papermaking and other industries due to their ability to dissolve in water.
- Medicine. Water soluble fibers have been widely used in medical treatment. They can be used for medical shielding materials and medical hygiene materials, such as disposable surgical gowns, caps, aprons, gauze, surgical dressing materials, medical sheets, work clothes, work caps, etc.
- Textile. In the textile industry, water soluble fibers are used for spinning to make high-end twist-free towels, bath towels, baby products, hotel supplies, etc. They can also be used as filling cotton in doll toys made of low-temperature water-soluble cloth and normal-temperature water-soluble thread.
- Papermaking. The papermaking industry uses water soluble fibers as adhesives to improve the strength and toughness of paper, thereby reducing the amount of wood pulp used, or reducing the paper weight while using the same pulp to improve paper quality.
