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.

Abstract

The invention relates to a manufacturing method of crepe paper, which comprises the steps of preparing wood pulp, beating, papermaking, corrugating, drying and the like. The wood pulp formed by mixing 5-30% of (w / w) hardwood pulp and 70-95% of (w / w) softwood pulp is matched with 0.5-10% of (w / w) wet strength agent, 1-10% of (w / w) sizing agent and more than 5% of (w / w) softening agent for use in the beating process, and the manufactured crepe paper is not damaged under the conditions of 125 DEG C, 5 atmospheres and more than 30 minutes and is especially suitable for the use in steam sterilization.

Description

technical field [0001] The invention relates to a method for manufacturing paper, in particular to a method for manufacturing crepe paper. Background technique [0002] Crepe paper is a general term for processed paper with a wrinkled surface. It is made of various pulps on a rotary paper machine. The texture of paper is generally soft, thin and highly absorbent. The paper quality of packaging paper is strong and elastic, and it is widely used in the fields of decoration, medical treatment and packaging. Wrinkle processing methods are divided into wet method and dry method: the wet method is to scrape out the wet (or not completely dried) base paper on the drying cylinder of the paper machine with a scraper or mechanically press out the wrinkles, and then dry them. The dry method is that the base paper is wrinkled by a scraper on the drying cylinder after drying. [0003] Chinese patent 00802034.5 describes a method of making crepe paper by placing the paper body on the s...
