Abstract
The invention provides antistatic viscose-fiber non-woven fabric. The antistatic viscose-fiber non-woven fabric comprises antistatic viscose fibers. The antistatic viscose fibers are obtained by modification of cross-linking of viscose fibers and epoxy-terminated polyethylene glycol bisepoxypropyl. The epoxy-terminated polyether contains polyether chain segments and terminals contain more than two epoxy groups. The antistatic viscose-fiber non-woven fabric has the advantages of high liquid absorption amount, good and lasting antistatic performance and high cleanliness and high strength. The invention provides a preparation method for antistatic viscose-fiber non-woven fabric. The method comprises the following steps of cross-linking modification, release, carding, transfer, mesh, spunlace, drying, winding, ultrasonic cleaning and clean packaging and the like. The technological process of the antistatic viscose-fiber non-woven fabric is simple and convenient to operate and eco-friendly and energy-efficient.
Description
technical field [0001] The invention relates to the field of wiping clean rooms and non-clean rooms, in particular to a non-woven fabric and a preparation method thereof. Background technique [0002] With the popularization and application of clean rooms and the continuous development of pollution control technology in the clean room industry, the use of clean room consumables is increasing. Among them, dust-free cloth is one of the main clean room consumables. Its main function is to remove products , production equipment and pollution sources in clean rooms. The traditional dust-free cloth base material is mainly woven from chemical fiber filaments such as polyester, nylon or composite yarn through textile equipment. The main advantage of chemical fiber filament is that it can remove the particles adsorbed on the surface of the filament during the ultra-clean cleaning process, and the cleanliness of the dust-free cloth produced is relatively high. However, woven fabrics...
