Abstract

The invention provides a biodegradable non-woven fabric. The biodegradable non-woven fabric is prepared from, by weight, 70-100 parts of acrylic-modified corn bran fiber, 30-50 parts of plant fiber, 20-30 parts of ofloxacin, 5-15 parts of silane coupling agent DL171, 5-10 parts of tween, 1-5 parts of 2,2'-sulfo-di(4-tert-octylphenol oxygroup) nickel, 1-5 parts of m-Phenylene dibenzoate, 1-10 partsof polysorbate80, 5-10 parts of fire retardant, 5-15 parts of antioxidant and 5-10 parts of plasticizer. The biodegradable non-woven fabric prepared with a method has good mechanical performance andfresh keeping performance, the cost is low, the biodegradation speed is high, and the biodegradable non-woven fabric is free of toxic and side effects on the environment.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a biodegradable non-woven fabric. Background technique [0002] With the continuous development of social economy, the demand for polymers has increased sharply, but most polymer materials are difficult to biodegrade, causing environmental pollution. Biodegradable materials are polymer materials that have good performance during use and can be naturally degraded after use. This material can significantly reduce environmental pollution. [0003] Polybutylene succinate (PBS) is a kind of fatty alcohol polymer, which can be completely biodegraded, but usually the preparation cost is high and the process is relatively complicated, and the fresh-keeping effect of the prepared non-woven fabric is poor. Currently published patents or documents are PBS fibers prepared by methods such as melt spinning and electrospinning. In the prior art, the invention patent with the publica...
