Specific embodiment
The application is described in further detail below by specific embodiment combination attached drawing.
As shown in Figure 1, a kind of preparation method of water repellency dressing, comprising the following steps:
S01: preparation
Water repellent aqueous solution is prepared, dressing substrate is prepared.
Dressing substrate can be cotton degreasing cloth, all cotton non-woven fabric or cotton blend non-woven fabrics etc..Water repellent aqueous solution is used
Upper one layer of water repellent layer 2 is covered in the surface for the fiber 1 for making dressing substrate.Manufactured water repellent aqueous solution is weakly acidic, and pH value is
4-7.On the other hand, water repellent aqueous solution is made of water repellent, and water repellent is fluorinated water repellent or siliceous class water repellent.
In one embodiment, water repellent be fluorinated water repellent, fluorinated water repellent include C4 organic fluorine,
At least one of C6 organic fluorine, the copolymer of C4 and C6 fluorochemical monomer, fluorine-containing siliceous copolymer, i.e. fluorinated water repellent packet
Containing more than one or more among them.In addition, the concentration of water repellent aqueous solution made of fluorinated water repellent is 5-
100g/L。
In another embodiment, water repellent is siliceous class water repellent, and siliceous class water repellent includes that straight chained alkyl is modified
At least one of silica solution, aliphatic group modified silicasol or silane coupler modified linear polysiloxane, i.e., siliceous class are refused
Aqua includes more than one or more among them.In water repellent aqueous solution, the concentration of siliceous class water repellent is 0.1-
10%, which is the mass concentration of solute.
S02: dipping
After the completion of the preparation of water repellent aqueous solution, dressing substrate is put into water repellent aqueous solution and is sufficiently impregnated.
In present embodiment, water repellent aqueous solution is poured into a sink, and dressing substrate, which is put into sink, to be impregnated, so that applying
Material substrate is sufficiently impregnated.As shown in Figure 2,3, the water repellent aqueous solution in sink coats the surface of the fiber 1 of dressing substrate
One layer of water repellent layer 2 is gone up.
S03: rolling
After the completion of dipping, rolling is carried out to the dressing substrate for being stained with water repellent aqueous solution, to get rid of extra water repellent
Agent aqueous solution.Pick-up after rolling is 60%-90%, and pick-up is also liquid carrying rate, be on fabric the liquid weight of band with knit
The percentage of object weight itself.
S04: song contracting
The step is optional process, is only used in the production of bent contracting cotton class dressing.When needing bent contracting, it is completed in rolling
Afterwards and before drying and dewatering, dressing substrate march contracting is handled.
In present embodiment, when cotton absorbent gauze is as dressing substrate, it can contract to cotton absorbent gauze march
Processing.After bent contracting processing, there is coiled structure in the warp direction of gauze, keeps gauze more fluffy, more three-dimensional, and permeability is also more
It is good.
S05: drying and dewatering
After completion rolling or after completing bent contracting processing, the processing of drying and dewatering is carried out to dressing substrate.
In present embodiment, drying and dewatering is baking area's completion, and dressing substrate is logical after completing rolling or completing bent contracting
