Abstract

The invention discloses a foam finishing solution for an antistatic PP spun-bonded non-woven fabric and an application thereof. The preparation method comprises the following steps: preparing a foam finishing solution; applying the prepared foam finishing solution to a PP spun-bonded non-woven fabric in a double-sided padding manner, performing double-sided foam finishing, and dipping twice and padding twice; and pre-baking the finished PP spun-bonded non-woven fabric at a temperature of 80-100 DEG C, and baking under the condition of 105-150 DEG C for 1-8 minutes, thereby obtaining the antistatic PP spun-bonded non-woven fabric subjected to foam finishing. The method disclosed by the invention is simplified in process, energy-saving, water-saving, less in sewage discharge, stable in production and high in production efficiency; and the prepared products are obvious in antistatic property and excellent in consistency, and can be widely applied to disposable medical protective clothing,operating coats, operation towels and other medical protective materials.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric processing and weaving, in particular to a foam finishing solution and a finishing method for antistatic PP spunbonded nonwoven fabric. Background technique [0002] Due to its low cost and high strength, PP spunbonded nonwovens are mostly used in the medical and health field to make disposable medical protective clothing, surgical gowns, surgical drapes, surgical bags, bed sheets, pillow covers, etc. Due to the particularity of the operating room, for disposable medical protective clothing and surgical gowns, in addition to having good drapability, shape retention, breathability, and moisture permeability, they also need to have antistatic properties to avoid causing fire or affecting doctors. Wearing comfort. Therefore, PP spunbonded nonwoven protective clothing, surgical gowns, surgical drapes, etc. generally require special antistatic finishing. Foam finishing technology uses air to ...
