Spunlace composite technology:

The research and development of spunlace composite technology not only overcomes the limitations of some non-woven products, increases the variety of patterns, greatly expands the application fields of spunlace non-woven fabrics, but also promotes the development and improvement of spunlace technology and even the entire non-woven fabric process.

 (1) Composite technology of spunlace and wood pulp airflow forms a web. Due to the fact that wood pulp is much cheaper than short fibers commonly used in spunlace process, and the moisture absorption and texture of fluff pulp are both good, the products made from it are cheaper than those made entirely from fibers, and are competitive in price, but have high requirements for filtration systems in terms of technology. The product can be used as the inner core material for diapers and sanitary napkins. The equipment for combining spunlace and wood pulp airflow into a mesh includes Aquapulp from Fleissner and Airace from Perfojet.

(2) Composite technology of spunlace and filament spun viscose fiber mesh. The composite product of this method combines the stronger market strength of spunbond non-woven fabric with better absorption performance of short fibers. It is also more uniform and soft than spunbond non-woven fabric, with water and oil absorption functions, and higher strength. It can be used as food packaging cloth, decorative cloth, and cleaning cloth, etc. The equipment for combining spunlace and spunbond methods includes Aquqspring and Aquasplit from Flerssner. And Freudenberg's Evolon processing technology.

(3) Spunlace and wet web formation composite technology. The typical process of Detex's Hydraspun technology is composed of Detex's wet web formation technology combined with the Soflom spunlace method registered by Japan's Unicharm company. The strength and softness of Hydraspun spunlace non-woven fabric are equivalent to or even exceed those of traditional dry spunlace non-woven fabric, and spunlace non-woven fabric does not shed debris. Its seam tensile strength is twice that of dry spunlace non-woven fabric, making it particularly suitable for the clothing industry.
