Abstract
The invention discloses a method for processing the fabric of a surgical gown with a permeability-resisting protection function. The method comprises the steps of nano-sol pretreatment, low-temperature normal-pressure air plasma treatment, chemical permeability resisting agent treatment and ultraviolet radiation. The fabric processed by the method disclosed by the invention achieves the effects of resisting the permeability of blood, alcohol, water and the like, and meets the protection requirements of the fabric of the surgical gown: the water repellency level is 8, the oil repellency level is 7, the alcohol repellency level is 10, the blood contact prevention angle is 126.2 DEG, the strong retention rate is 92.6%, and the permeability retention rate is 95.3%.
Description
Technical field
The present invention relates to a kind of processing method with the operation dress fabric of impervious safeguard function.
Background technology
China has promulgated GB19082-2003 " disposable medical protective clothing technical requirement " on April 29th, 2005, and regulation medical protective garment must have liquid barrier performance (comprise water proofing property, dextran penetrate and spray rating).Barrier can be subdivided into again liquid (as water, alcohol, blood, wet goods); medical material only can intercept the infiltration of aforesaid liquid well, could protect medical personnel well not by courses of infection and the infection rate greatly reducing patient in surgical procedure.In China due to the lower consumption level, the consumption idea of patient and medical personnel and relevant law and code not well established and perfect, cause the domestic use lack of knowledge for medical protection articles for use.
The C of current impervious use
8-10pFOS (PFO base sulfonyl compound) and the PFOA(perfluoro caprylic acid of international forbidding is there is in fluorine-contained finishing agent), adverse environment is protected.And need to be baked by high temperature in general finishing technique finishing agent is effective, but the non-refractory that the nonwoven of operation dress is furnished with, machinery is powerful to decline seriously, have impact on wearability.
Summary of the invention
The object of the present invention is to provide a kind of processing method with the operation dress fabric of impervious safeguard function that can meet operation antiseepage requirement.
Technical solution of the present invention is:
There is a processing method for the operation dress fabric of impervious safeguard function, it is characterized in that: comprise the following steps: successively
(1) Nano sol preliminary treatment:
The preparation of Nano sol: by tetraethyl orthosilicate, ammoniacal liquor, ethanol, by the mixed in molar ratio of 1:16:60, at 30 DEG C of-80 DEG C of magnetic agitation 1-6 hour, places 2-24 hour for 20-30 DEG C;
Processing method: operation dress fabric is carried out in Nano sol two leachings two and roll process, liquid carrying rate 100%, ventilative 15min;
(2) low-temperature atmosphere-pressure air plasma process:
The operation dress fabric that will process through step (1), carries out plasma treatment: DC voltage 400 V, power 1 kW, frequency 200 Hz, processing time 1min, gas: air under following treatment conditions;
(3) chemical permeability-reducing admixture process:
The operation dress fabric that will process through step (2), in permeability-reducing admixture, carry out many leachings one roll process, liquid carrying rate 100%, permeability-reducing admixture is that C6 fluorochemical repellent finish and C16 silicon system water repellent form by the weight ratio of 5:1-1:1 is composite, consumption 10-60g/L; 80 DEG C of drying and processing 10min;
(4) ultra-violet radiation
24W uviol lamp radiation 2 hours.
The present invention's low-temperature atmosphere-pressure air plasma and ultra-violet radiation replace traditional high temperature to bake set technique, ensure that the brute force of fabric; Ultra-violet radiation set and sterilization carry out simultaneously; Jointly construct rough surface with Nano sol and the process of low-temperature atmosphere-pressure air plasma, improve the action effect of chemical impervious agent; Chemical impervious agent used is C
6fluorochemical repellent finish and C
16silicon system water repellent composite (5:1-1:1), the PFOS (PFO base sulfonyl compound) of Bu Han world forbidding and PFOA(perfluoro caprylic acid), meet environmental requirement.The fabric of the present invention's processing reaches the impervious effect to blood, alcohol, water etc., meets the requirement of shelter of operation dress fabric: refuse water grade 8 grades, refuses wet goods level 7 grades, refuse alcohol 10 grades, refuse contacting blood angle and reach 126.2 °, strength retention 92.6%, air penetrability retention rate 95.3%.
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are the photo that processing fabric anti-leakage liquid drips for water, oil, alcohol, blood are respectively.
Detailed description of the invention
There is a processing method for the operation dress fabric of impervious safeguard function, comprise the following steps: successively
