Embodiment 1
[0024] After mixing 20% (w / w) hardwood pulp and 80% (w / w) softwood pulp, it is beaten. Add 2% (w / w) melamine, 5% (w / w) AKD sizing agent (Qingzhou Jinhao Chemical Co., Ltd.) and 5.7% (w / w) SFI softener (Jiangmen Daming Paper Industry Co., Ltd.) Ltd.). After beating for 3-4 hours, the humidity of the slurry is 2.0-2.5g, and the viscosity is 65°SR-75°SR; the pulp is made into a paper embryo at a speed of 20m per minute, and it is creped by a scraper crepe method and then dried Instantly.
[0025] The prepared crepe paper wrapped surgical medical appliance was sterilized at 125° C. and 5 atmospheres for more than 30 minutes. After taking it out, the crepe paper was intact and no damage was found.
Embodiment 2
[0027] After mixing 20% (w / w) hardwood pulp and 80% (w / w) softwood pulp, it is beaten. Add 1.3% (w / w) polyamide epichlorohydrin, 5% (w / w) AKD sizing agent, 7.2% (w / w) SFI softener and indigo while beating. After beating for 3-4 hours, the humidity of the slurry is 2.0-2.5g, and the viscosity is 65°SR-75°SR; the pulp is made into a paper embryo at a speed of 20m per minute, and it is creped by a scraper crepe method and then dried Instantly.
[0028] The prepared crepe paper wrapped surgical medical appliance was sterilized at 125° C. and 5 atmospheres for more than 30 minutes. After taking it out, the crepe paper was intact without damage or fading.
Embodiment 3
[0030] After mixing 20% (w / w) hardwood pulp and 80% (w / w) softwood pulp, it is beaten. While beating, add 1% (w / w) polyamide epichlorohydrin and 1% (w / w) melamine, 5% (w / w) AKD sizing agent, 7.2% (w / w) SFI softener and indigo. After beating for 3-4 hours, the humidity of the slurry is 2.0-2.5g, and the viscosity is 65°SR-75°SR; the pulp is made into a paper embryo at a speed of 20m per minute, and it is creped by a scraper crepe method and then dried Instantly.
[0031] The prepared crepe paper wrapped surgical medical appliance was sterilized at 125° C. and 5 atmospheres for more than 30 minutes. After taking it out, the crepe paper was intact without damage or fading.
