Abstract

The invention discloses a finishing process of a polypropylene operating coat, and relates to the technical field of operating coat finishing processes. The finishing process comprises the following steps: 1, melting; 2, fabric preparation; 3, sewing; 4, finishing agent preparation, wherein a finishing agent is proportioned by the following components by weight: 50-60 parts of isotridecyl alcoholpolyoxyethylene ether, 8-15 parts of tween-65, 12-19 parts of polyethylene glycol glyceryl ether, 1-5 parts of N-cetylpyridinium chloride, 10-20 parts of water, 5-10 parts of an antistatic agent and 7-12 parts of a penetrating agent, 5, dipping; 6, baking; and 7, sterilizing. According to the invention, the antistatic agent TF-481 and the penetrating agent TF-1010S are added into the finishing agent, and the anti-alcohol, anti-blood and anti-static effects of the polypropylene operating coat are enhanced, and meanwhile, the original fiber net structure and the mechanical property stability ofthe polypropylene operating coat are kept.

Description

technical field [0001] The invention belongs to the technical field of finishing technology for surgical gowns, in particular to a finishing technology for polypropylene surgical gowns. Background technique [0002] Medical non-woven fabrics have the characteristics of high filterability to bacteria and dust, low surgical infection rate, convenient disinfection and sterilization, and easy compounding with other materials. As disposable medical products, non-woven products are not only hygienic and convenient to use, but also effective. Effectively prevent bacterial infection and iatrogenic cross-infection. With its outstanding hydrostatic pressure resistance, nonwoven materials take the lead in the market of disposable medical surgical gowns, but they must be finished to reduce the surface tension of the fibers in order to have the "three anti-alcohol, anti-blood, and anti-static functions". Most of the three anti-finishing agents currently used are fluorine-containing surf...
