The spunlace method, also known as the spunlace method, is an important non-woven fabric processing technology. Due to the unique process technology of the spunlace method, it is widely used in the fields of medical and health products, synthetic leather base fabrics, shirts, and home decorations. . Its fiber raw materials have a wide range of sources, such as polyester, nylon, polypropylene, viscose, etc. At present, the main uses of spunlace cloth are three categories, namely medical, artificial leather and cleaning. Its sales direction: artificial leather spunlace cloth is mainly for domestic sales, medical spunlace cloth is mainly exported for export, and cleaning spunlace cloth Export and domestic sales each account for a part.
Product characteristics of spunlace non-woven fabrics: soft, fluffy, high moisture absorption, and a certain degree of oil absorption.

Needle-punched non-woven fabric overview
　 is a type of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the puncture effect of needles to reinforce the fluffy web into a fabric.

Common specifications of needle punched non-woven fabrics
Weight: (100—1000)g/㎡, thickness: ≥5mm, width: ≤210cm

Needle punched non-woven fabric materials and processing procedures

　　 is made of polyester and polypropylene raw materials, after carding, combing, pre-needling, and main needling. The center is interlayered with mesh cloth, and then through double nucleation, air-laid and needle-punched composite cloth, the post-press filter cloth has a three-dimensional structure. After heat setting and singeing, the surface is treated with a chemical oil agent to make the filter cloth The surface is smooth, and the micropores are evenly distributed. From the surface, the product has good density, smooth and air-permeable surfaces on both sides. It is proved that the filter on the plate and frame compressor can use high-strength pressure and the filtration accuracy is up to 4 microns. Need to provide polypropylene and polyester two kinds of raw materials. Practice has proved that non-woven filter cloth has better performance in plate and frame pressure filtration: for example, coal slurry treatment in coal preparation plants, wastewater treatment in iron and steel plants, wastewater treatment in breweries, printing and dyeing plants. If other specifications of filter cloth are used, filter cake pressure will appear. The problem of non-drying and difficult to fall off. After using non-woven filter cloth, the filter cake will be quite dry when the filter pressure reaches 10kg-12kg, and the filter cake will automatically fall off when the filter frame is opened. When users choose non-woven filter cloth, they mainly consider non-woven filter cloths of different thickness and quality according to air permeability, filtration accuracy, elongation, etc. Please click polyester needled felt and polypropylene needled felt for product parameters. The specifications and varieties are all Can be formulated.

The series of needle punched non-woven fabrics are formed through fine carding, multiple precision needle punching or proper hot rolling. Based on the introduction of two high-precision acupuncture production lines at home and abroad, high-quality fibers are selected, through the coordination of different production processes, and the combination of different materials, hundreds of different products are currently circulating on the market, mainly including: geotextile, geomembrane , Velvet cloth, speaker blanket, electric blanket cotton, embroidered cotton, clothing cotton, Christmas crafts, human leather base cloth, filter material special cloth.
The apparent difference between the two: spunlace non-woven fabrics are lighter, thinner, finer, soft, fluffy, highly hygroscopic, and have a certain oil absorption effect; while needle-punched non-woven fabrics are thicker and rougher.
