Embodiment 1

[0022] Embodiment 1, as shown in Figure 4, the process flow mainly includes the following steps: raw material screening - liquid defibration - cleaning - rinsing - liquid opening - dehydration and drying - opening and removing impurities - Carding - pulping - papermaking.

[0023] Process description:

[0024] (1). Raw material screening: choose at least one of the animal leathers of cattle, sheep, pigs, dogs and other animals, their leftovers and waste and recycled materials.

[0025] (2). Liquid cleaning: add 40 times the liquid into the ultrasonic cleaning machine, add NaOH to the liquid, and the pH value is between 10 and 11; the liquid temperature is 40 to 60 ° C, and the ultrasonic vibration (frequency is 20 to 40KHZ) Clean for 30-60 minutes and stop.

[0026] (3). Rinse: Rinse 2 to 3 times in an industrial washing machine at room temperature. If the raw material is artificially colored, in the first cleaning, you can add carving white powder equivalent to 2-6% of the...

Embodiment 2

[0037] Embodiment two, technological process are the same as embodiment one.

[0038] Process description:

[0039] (1). Screening of raw materials: Gray skins of various animals before tanning and other papermaking fibers are used.

[0040] (2)-(7) are the same as the first embodiment.

[0041] (8). Pulping: based on solid weight, 90% of collagen fibers and 10% of other papermaking fibers. Using the existing papermaking pulping process, mix collagen fibers and other papermaking fibers with water and add dispersants, adhesives, etc. for papermaking Additives are stirred into a slurry.

[0042] (9). Papermaking: Same as Example 1.

[0043] Through the above steps, a mixed paper mainly composed of collagen fibers is obtained.

Embodiment 3

[0044] Embodiment three, technological process are the same as embodiment one.

[0045] Process description:

[0046] (1). Use shaved leather scraps and other papermaking fibers in the tanning process.

[0047] (2)-(7) are the same as the first embodiment.

[0048] (8). Pulping: In terms of solid weight, 30% of collagen fiber and 70% of other papermaking fiber. Add collagen fiber to other papermaking fiber slurry that has been prepared, and then add papermaking auxiliary agents such as dispersant and adhesive Perform secondary pulping.

[0049] (9). Papermaking: Same as Example 1.

[0050] Through the above steps, the obtained mixed paper is mainly composed of other papermaking fibers and collagen fiber is a special component.

Abstract

The present invention discloses a kind of paper made of collagen fiber and its processing method. The paper made of collagen fiber includes fiber component and non-fiber component; said fiber component is formed from 10-100 wt% of collagen fiber and 0-90 wt% of other fiber for making paper. Its processing method mainly includes the following steps: screening raw materials, liquid defibrination, cleaning, rinsing, and opening by using liquor, dewatering and drying, opening and removing impurity, carding, pulping and papermaking.

Description

Technical field: [0001] The invention relates to the technical field of paper products, in particular to a paper made of animal skin or leather collagen fibers and a processing method thereof. Background technique: [0002] Paper is a necessity of human life. There are many types of paper, with different raw materials, different processes, and different uses of paper. Papermaking is inseparable from fibers, and the type and quality of fiber raw materials are not only related to the varieties and uses of the papermaking industry, but also related to the impact of the industrial system on nature. The fibers currently used in the paper industry are mainly wood fibers, non-wood fibers (bamboo, wheat straw, reed, etc.) and secondary fibers. Due to the limited quality of the fibers, the paper produced is of poor quality and damages natural resources. Chemical fiber is also a raw material for the paper industry, but the cost of chemical fiber is too high, so it can only be used t...
