Memis Acar from the Department of Mechanical Engineering at Loughborough University in the UK has demonstrated that the water jet process can process fiberglass and produce industrial fabrics. However, due to the non curling nature of fiberglass, traditional beliefs suggest that dry non-woven processes are difficult to process. Most fiberglass nonwoven fabrics are generally processed by needle punching or wet process, but North Carolina State University (NCSU) in the United States has successfully developed a water spunlaced nonwoven fabric that blends fiberglass and polyester. Coarse denier fiberglass with a diameter of 16um is difficult to process by water piercing. If mixed with fine denier fiberglass with a diameter of 6.5um, it is beneficial to improve the strength of water piercing nonwoven fabrics. Therefore, when mixed with different fiber sizes, fine denier fibers are conducive to water piercing, while coarse denier fibers are conducive to improving the strength of water piercing nonwoven fabrics. If fiberglass is mixed with textile staple fibers such as polyester, it can enhance the ability of water jet entanglement. Mixing fiberglass with low melting point polyester can produce fiberglass reinforced polyester composite materials.
Researchers from Auburn University in the United States have discovered using NGSN equipment that the water jet method can produce geotextiles, which are produced by needle punching and hot rolling processes. Researchers have found that changing the water jet pressure and the duration of water needle action on the fiber mesh can alter the pore size of geotextiles. Aperture is a key indicator of geotextiles, especially when used as a sand filter layer, allowing water to flow through and preventing soil movement. Extending the time of water needle action on the fiber mesh or increasing the water needle pressure can enhance the water needle entanglement effect of the fiber mesh and reduce the pore size of the fabric. The aperture size can be adjusted online without stopping, thereby improving production speed and being more flexible and simple than other processing techniques of geotextiles.
New technology for fabric functional finishing: In 1995, BBA Company in the United States developed the Interspun process and applied for a patent. By using this process, the surface of the fabric can be treated with water jet, which can have a positive impact on the structure and properties of the fabric. In 1998, BBA Company signed a cooperation agreement with Fleissner Company, which was the exclusive machine supplier for this technology. Fleissner's Aquatex is a system that uses water jet to treat woven fabrics, known as a revolutionary measure in the post-treatment process of woven fabrics. After undergoing water jet treatment on woven fabrics, the yarns in the fabric are loosened and the fabric is effectively cleaned; Depending on the arrangement of water spikes, the effect of peach skin velvet can be achieved on both sides or one side of the fabric; It can also eliminate the stress generated by the fabric during the manufacturing process, making the warp and yarn more uniform, thereby improving the texture and appearance of the fabric, increasing the thickness of the fabric, making the luster of the fabric soft, and the wear resistance more than 300% of that before treatment. The slipping phenomenon at the sewing point is reduced by more than twice, and the anti pilling performance is improved, the wrinkle resistance is improved, the fabric surface is more uniform, the fabric surface pores are reduced, and the distribution is more uniform, Used for dyeing cotton fabrics as if they have undergone mercerization treatment. Therefore, after being treated with water treatment, processes such as desizing, boiling, mercerization, and sanding can be eliminated, and the bleaching process can also be simplified, which has significant comprehensive economic benefits. The product is widely used in decorative fabrics, filter fabrics, household textiles, clothing, and automotive safety airbag fabrics.
