In 1995 the United States BBA company developed the Interspun process and applied for a patent. Using this process, the surface of the fabric can be treated by hydroentangling, which can have a positive effect on the structure and properties of the fabric. In 1998 BBA signed a cooperation agreement with Fleissner, Fleissner for the exclusive machine supplier for this technology. Fleissner’s Aquatex is a system that uses a spunlace head to machine woven fabrics and is known as a revolutionary step in the finishing process. The fabric in the spunlace after the release of the yarn in the fabric, and the fabric is effectively clean; according to the layout of the spunlace, the two sides or one side of the fabric can get the effect of jeanette; Fabric stress generated during the process, so that more uniform between the warp, thereby improving the fabric feel and appearance, increase the thickness of the fabric, so that the fabric soft luster, abrasion resistance is not treated before more than 300%, sewing Department of slippage The anti-pilling property is improved, the cloth surface is more even, the cloth surface porosity is reduced, the distribution is more even, and the cotton fabric is dyed like the mercerizing treatment. So after spunlace treatment can be canceled desizing, scouring, mercerizing, sanding and other processes, bleaching process can also be simplified, with a very obvious comprehensive economic benefits. Products are widely used in Zhuang Shibu, filter cloth, home textiles, garments, automotive airbags fabric.
