Bacteria resistance detection: taking staphylococcus aureus and Escherichia coli, and turbidity containing bacterium number is the bacteria suspension of 0.5mcf, with doctor Bacterium is evenly coated in put down with cotton swab and is pulled, every kind of bacterium repeats 3 pieces of plates, on the super-clean bench, will be obtained de- with sterile mirror Rouge cotton gauze is attached on ware containing bacterium, and the antibacterial bacteriostatic rate around degreasing cotton gauze is surveyed after cultivating 24 hours in insulating box；
The test of gauze absorbent: it referring to the hygroscopic method of surface of a wound dressing is commonly tested in the world, is weighed using moisture absorption Method tests the absorbent of gauze, concrete operations are as follows: tailor 5cm × 5cm gauze, accurately weigh up its dry weight W0, it is put into 100mL In deionized water, imbibition 30min takes out gauze, naturally flatly after vertical hanging 30s, weighs cotton gauze weight W at once1, yarn Imbibition rate Q=(W of cloth1−W0)/W0；
Table 1
There is excellent antibacterial bacteriostatic performance and absorbent according to the modified absorben cotton gauze of present invention method preparation, Air penetrability is 3890mm/s, and the imbibition of modified absorben cotton gauze, ventilative, softness is good；
It is not added in comparative example 1 using kuh-seng seed flavones sustained release pellet, causes modified absorben cotton gauze to golden yellow The antibacterial bacteriostatic performance of staphylococcus and Escherichia coli reduces, but presses down still better than the antibacterial of control group blank degreasing cotton gauze Bacterium performance；Be not added in comparative example 2 causes the imbibition rate of modified absorben cotton gauze to reduce using water-absorbent material, still Still better than the absorbent of control group blank degreasing cotton gauze.
