Polyvinyl alcohol water-soluble fiber is a fiber made of polyvinyl alcohol as raw material through wet spinning, heat treatment, warm water crimping, and oiling. The product has good physical and mechanical properties, corrosion resistance, acid and alkali resistance, and dry heat stability. The biggest feature is that it can be dissolved in water at a temperature of 86-95°C.
The company's annual production capacity of water-soluble PVA fiber products is 10,000 tons, which has solved the technical problems that affect the processing performance such as oil selection and insoluble content. The product technology is mature, the quality is stable, and all technical indicators have been tested. International advanced level in the same industry. The product has passed ISO9001 quality management system and ISO14001 environmental management system certification.

Technical Details & Test Data
- Technical Information
Water-soluble polyvinyl alcohol (PVA) fiber is a kind of cotton-like synthetic fiber, which has been widely used in agriculture, light industry, textile, military, medical and other fields in recent years.
Water-soluble PVA fiber not only has ideal water solubility temperature, strength and elongation, but also has good acid resistance, alkali resistance and dry heat resistance. It is also tasteless and harmless after being dissolved in water. The aqueous solution is colorless and transparent. In a short time It can decompose naturally and does not cause any pollution to the environment. It is a 100 precent green product.
Secondly, according to recent research results, PVA is the only material that is soluble in water and biodegradable among synthetic fiber-forming polymers. It is precisely because of the water-soluble properties of PVA fibers that the development and application of water-soluble PVA fibers with different properties are still expanding.
It can be blended with cotton or other fibers into fabrics. After processing, the water-soluble fiber components in the fabric can be dissolved, which can greatly improve the style and grade of the fabric. The home textile industry uses the special properties of water-soluble fibers to develop a variety of new products. The products have stimulated market vitality with novel appearance, novel effects and special touch.
Water-soluble PVA fiber is a kind of vinylon fiber products. Water-soluble PVA fiber is ideal because of its water-soluble properties (dissolvable in hot water below 95℃) and high strength (1.5 to 3 times that of ordinary cotton). Emerging green fiber.
In the textile industry, water-soluble fibers are used to spin high-count yarns, and the water-soluble fiber blending process can be applied to improve product quality and expand the scope of fabric design. Using water-soluble fibers as reinforcing fibers, blended with hemp or wool to form yarns and then water-soluble to remove synthetic fibers, a uniform and slender high-count pure hemp or pure wool yarn is obtained. This method can be used to spin high-count wool fabrics. And hemp yarn.
The non-woven fabric made of water-soluble PVA fiber can be used as the computer embroidery base fabric, which is more three-dimensional and softer than the embroidery of other fiber base fabrics. These new types of applications do not need to introduce equipment or carry out equipment transformations, and low-cost raw materials can be used to produce high-end products, which greatly reduces production costs.
Water-soluble PVA fiber products are processed into water-soluble non-woven fabrics, which can be used as secondary fabrics such as medical surgical gowns, surgical caps, masks, surgical towels, etc.; its pure woven gauze can be used as medical non-stick gauze; it also pioneers medical waste pollution A new way of environmental protection treatment.
With its high-strength fiber spun into high-strength yarn, it is used to make recyclable and reprocessed quality packaging bags such as cement bags, feed bags, etc. Because the water-soluble fiber has solubility properties, the low-temperature water-soluble fiber is mixed with the pulp to make a seedling paper tube, which can realize mechanical seeding, and it can be naturally degraded without affecting the quality of the soil. With the continuous excavation of its unique water-soluble energy effect, the application field is becoming more and more extensive.- Specifications
Our company can produce 1.11dtex～2.00dtex, with a length of 30mm～40mm polyvinyl alcohol water-soluble short fiber.
