Water-Soluble Nylon Island Fiber Nonwoven Fabric

Water-reduced sea island fiber needle-punched nonwoven fabric is a composite material that combines sea island fiber technology, needle-punching molding process and water-reducing treatment. Its core processes include:

1. Preparation of sea island fiber: Polyester or nylon (island component) and water-soluble polyvinyl alcohol (sea component) are melt-spinned to form a sea island structure.

2. Needle-punching molding: After the sea island fiber is air-laid, the entanglement between fibers is enhanced by mechanical needle-punching process to form a non-woven fabric substrate.

3. Water-reducing treatment: The needle-punched nonwoven fabric is immersed in 85-90℃ hot water to dissolve the sea component (polyvinyl alcohol) and retain the ultrafine polyester fiber (island component) to form a porous, high specific surface area structure.

Product Details

Weight: 280-800g/m2
Width: 1.6-1.75m

Technical advantages

1. Ultrafine fiber characteristics: After water reduction treatment, the diameter of the island component polyester fiber can reach micron level, which significantly improves the filtration accuracy of the material (such as air filtration efficiency of 99.9%.

2. Environmental protection: Water-soluble polyvinyl alcohol is used as the sea component to reduce the use of chemical solvents and make the production process greener.

3. Structural stability: The needle punching process enhances fiber entanglement, and the water reduction treatment avoids fiber damage. The finished product has both high strength and flexibility.

Application areas

1. High-end filter material: used for air purifier filter elements and industrial dust filtration devices, especially suitable for processing ultrafine particles such as PM2.5

2. Medical and health care: As the base material of medical protective clothing and masks, it has high air permeability and barrier properties.

3. Synthetic leather base fabric: Through processes such as impregnation with polyurethane, it is made into simulated leather, which is widely used in automobile interior and luggage manufacturing.

ABOUT Hengqide

Ningbo Hengqide Chemical Fiber Technology Co., Ltd. is located in Qianwan New District, is specialized in the production of water-soluble island fiber science and technology innovation company. The company focuses on combining with the major strategic needs of the country, taking green production as its responsibility, aiming at the safety hazards and environmentally unfriendly pain points such as large emission of waste gas and waste in the follow-up production process of the current island fiber microfiber benzene reduction and alkali reduction, after nearly ten years of dedicated research and development, the company has remodeled the synthesis of microfiber materials and innovated the production process of microfiber leather. Successfully invented fully water-soluble island fiber. Water-soluble island fiber is currently the only technology in the world that uses pure water reduction to open the fiber, the production of fiber non-woven fabric uses water-based resin immersed in water coagulation process, with 95℃ hot water to complete the reduction process, which can effectively separate the island (polyvinyl alcohol) components in the fiber, from the fiber production to the bass process, without the use of any harmful chemicals. It does not produce substances that pollute the environment such as toluene, DMF, phthalic acid, etc., so as to recycle water resources and recycle PVA (Marine materials). At the same time, ensure that the physical properties of microfiber are intact after water reduction, and the color silk is more bright and bright, and the color fastness is better. This revolutionary technology truly realizes the full range of green coverage from raw materials to finished products, fully demonstrating the excellent practical quality and efficient environmental protection value of water-soluble island fiber. Ningbo Hengqide Chemical Fiber Technology Co., Ltd. has all the independent intellectual property rights of the invention, obtained five national invention patents and three utility model patents; At the same time, it won the "13th Five-Year" excellent science and technology Achievement Award of China Plastics Processing Association, and was included in the "14th five-year" frontier technology research, key common technology research and industrialization development and promotion of one of the important projects; To this end, the All-China Environmental Protection Federation and the Committee of Energy and Environment issued opinions on the promotion of green environmental protection products "Replacing chemical solvent island fiber with water-soluble island fiber". Ningbo Hengqide Chemical Fiber Technology Co., LTD., with a vigorous trend, brave to stand at the forefront, dare to be the first. Adhering to the concept of enterprise service to society, innovation and development, natural harmony, drawing cutting-edge wisdom, and gathering scientific and technological strength, we sincerely look forward to cooperating with the world's outstanding enterprises, pragmatically promote the wider application of water-soluble island microfiber in production, textile, leather, fashion and other fields, and create a better future of green environmental protection in the industry. To achieve a harmonious coexistence between man and nature through industrial upgrading and scientific and technological innovation. Look at the bay winds and clouds, hand in hand, strive ahead. Ningbo Hengqide Chemical Fiber Technology Co., Ltd. looks forward to working with you to create a green tomorrow and create a better future!
