Tissue paper has been an important part of the papermaking industry for many years. Today, the continuous growth in the production capacity of colored tissue paper is achieved through new technologies that meet the quality of the product. The development of multi-layer pulp box provides the opportunity to use different primary fibers and secondary fibers at the same time in the production of sheet paper and makes the final products multi-functional. In a multi-layer head box, a single layer of paper is usually formed by a combination of two ingredients or three layers of fiber. Tissue paper is produced on a paper machine that has a single large steam heated drying cylinder (yankee dryer) fitted with a hot air hood. The raw material is paper pulp. The yankee cylinder is sprayed with adhesives to make the paper stick. Creping is done by the yankee's doctor blade that is scraping the dry paper off the cylinder surface. The crinkle (creping) is controlled by the strength of the adhesive, geometry of the doctor blade, speed difference between the yankee and final section of the paper machine and paper pulp characteristics.
In addition to the use of multi-layer head box, concentration dilution distribution technology can reduce the quantitative change of paper pages. This technology can easily be used after modification of the existing paper machine. Especially for multiple layers. The quantitative distribution can be reduced from 2.0% to 1% by using the concentration dilution and distribution technique in the head box. Reduce the quantitative fluctuations of the page and produce a uniform sheet of paper.
Crepe paper sheets Tissue paper is a lightweight paper or, light crepe paper. Tissue can be made both from virgin and recycled paper pulp. Key properties are: strength, absorbency, basis weight, thickness (bulk), brightness, stretch, appearance and comfort.

EVA is a kind of material that we often see in our lives, but many people are not particularly familiar with EVA. What kind of material is EVA foam? What are the uses of EVA? Next, this article will tell you about EVA. Information.
1. What is EVA material?
EVA is a very common material. It has vinyl acetate monomer in its composition, which improves flexibility and impact resistance, compatibility, and heat tight sealing performance. It has good cushioning, shock resistance, heat insulation and moisture resistance. It is extremely resistant to corrosion and is non-toxic and non-absorbent. Most of the slippers sold in the mall are made of eva foam sheets and rubber. It is a relatively common midsole material. It usually has a strong cushioning function and function, but this material is very slippery, so it is usually mixed with hard rubber. Use.
2. What are the usages of EVA?
EVA has strong water resistance, can close the cell structure, and has strong non-absorbent and moisture-proof properties. EVA is very resistant to corrosion: corrosion, alkali and acid. EVA's precision processing: no joints, easy to heat compression, split, paste and other processing. EVA anti-vibration: high shock resistance and cushioning performance. The EVA resin is an ethylene-vinyl acetate copolymer, and the content of vinyl acetate (VA) is generally 5% to 40%. Compared with polyethylene, EVA is widely used in foaming shoes due to the introduction of vinyl acetate monomer in the molecular chain, which reduces high crystallinity, improves flexibility, impact resistance, filler compatibility and heat sealing performance. Materials, functional shed film, packaging film, hot melt adhesive, wire and cable and toys. In general, the performance of EVA resins depends primarily on the content of vinyl acetate on the molecular chain. Regarding the materials of EVA and the use of EVA, through the reading of the article, everyone has already had a certain understanding and understanding of this material of EVA. I hope this chapter can help everyone.
There are two main types of origami paper, one side with color, one side with white double-color paper, to fold two-color small works or hands-on use of this is very suitable.
Tissue paper is of better quality. Of course, the price is relatively high. The online purchases are 15cm in size and rich in color. I have not used this kind of paper folding, so I can not describe it. However, referring to the paper folding works, the thickness and toughness should be good. It can be used to fold some relatively complex small things or a good choice.
On paper selection, the paper usually selected is thin and moderately tough.
I recommend that origami players use hand rubbing paper and kraft paper. Experts can use wax paper and copy paper to their friends. This is the usual choice. Players can try other kinds of paper if they have the conditions. In particular, conditional players can also make their own paper. Kraft paper, used as packaging material. High intensity. Usually yellowish brown. The semi-bleached or fully bleached kraft pulp is light brown, cream or white. Quantitative 80~120g/m2. The crack length is generally above 6000m. Tear strength, breaking work and dynamic strength are high. Mostly web and flat paper. The sulphate softwood pulp is used as raw material, and it is beaten and made on a long net paper machine. Can be used as cement bag paper, envelope paper, rubber seal paper, asphalt paper, cable protective paper, insulation paper, etc. Kraft paper is a tough, water-resistant packaging paper that is brownish yellow and has a wide range of uses. It is commonly used in paper bags, envelopes, workbooks, record covers, dossier and sandpaper. The quantitative range is from 80 g/m2 to 120 g/m2. There are differences between single-sided, double-sided and striped in web and flat paper. The main quality requirements are flexible and strong, with high bursting resistance, and can withstand large tensile forces and pressure without breaking. Kraft paper has a high tensile force, such as single light, double light, stripes, no grain, and the like. Mainly used for wrapping paper, envelopes, paper bags, etc. and printing machine drum lining. Kraft paper usually maintains its yellow-brown color and is suitable for bags and wrapping paper. Kraft paper has a variety of uses depending on the nature and use. Kraft paper is a general term for a piece of paper. There is no specific specification. It is generally classified according to its nature and use. According to the color, it can be divided into: original color kraft paper, red kraft paper, white kraft paper, flat kraft paper, single-light kraft paper, two-color kraft paper, and the like.
According to the different uses, it can be divided into: packaging kraft paper, waterproof kraft paper, moisture-proof kraft paper, anti-rust kraft paper, patterned kraft paper, process kraft paper, insulated kraft paperboard, leather stickers and so on. According to the different materials, it can be divided into: recycled kraft paper, cowhide core paper, cowhide base paper, rough kraft paper, cowhide wax paper, wood pulp kraft paper, composite kraft paper and so on.
Advantages: In terms of environmental protection, most of the non woven felt sheet used are made of polypropylene, while plastic bags are made of polyethylene. Although the names of the two substances are similar, the chemical structure of the two substances is very different. The chemical molecular structure of polyethylene is very stable and difficult to degrade, so it takes 300 years to decompose the plastic bag. But the chemical structure of polypropylene is not firm, the molecular chain can be broken easily, so it can be effectively degraded, and in the non-toxic form into the next environmental cycle, a non-woven shopping bag can be completely decomposed in 90 days. And non-woven shopping bags can be reused more than 10 times, abandoned After the pollution to the environment is only 10% of the plastic bag.
Shortcomings:
1) compared with textile cloth, the strength and durability are poor. 2) cannot be washed like any other cloth.
3) the color felt is arranged in a certain direction, so it is easy to split from the right angle and so on. Therefore, the improvement of production methods is mainly focused on the improvement of preventing split.
In industrial products and medical products, the raw material of cellophane paper is often used because it has various high-quality features such as moisture resistance, high temperature resistance and oil resistance, which will be applied to many industries and is highly praised by everyone. Our daily use of barcodes, tapes or some special labels will use cellophane paper. Here are some details about what it has:
1, Good texture
Because the texture of the glass is very fine and uniform, it has strong transparency and strength. Generally, the top-grade cellophane paper can make its quality better when adjusting the uniformity of the thermal paper. It is a common material when it is not self-adhesive. It is precisely because this super-quality paper will play its role in more fields.
2, Waterproof and oil resistant
Another important feature of cellophane paper is its waterproof and oil-repellent properties. Therefore, this paper will be used as an important raw material for making label paper or thermal paper, so that the produced thermal paper and coated paper have good properties. The oil-proof and waterproof effect can be applied to special industries or fields in daily use to prevent oil and water from damaging the paper. 3, High internal strength Because the internal strength of the glass paper is higher than that of the general paper, the strength of the processed thermal paper or other papers will be high, so it will be very durable and can be used more. Years, to a certain extent, is also a cost-saving paper that can be used to the maximum extent, thereby improving cost performance and being very economical.
About the three characteristics of cellophane paper, I would like to introduce you here. I hope that you can have a certain understanding and understanding of cellophane paper through the above characteristics. If you want to buy a professional packaging cellophane paper, then To consult a few more manufacturers, mainly consider the quality of the paper, and then comprehensively compare all aspects, and finally select a satisfactory cellophane paper.

color paper is used both in daily life and in printing. It usually takes a long time to store from production to use, so it is very important to keep the color paper sheet well.
The size of the color glitter paper to reduce and air, moisture and sunlight contact, to avoid moldy yellow. The color paper sheet is basically stored in the storeroom, very few are also stored in the open air cargo yard, when keeping the color paper sheet generally, should pay attention to the color paper sheet storehouse to keep dry, avoid the phenomenon of leaking rain, the window should be small and high, avoid the exposure of sunshine. This color paper sheet temperature and moisture evaporation resulting in color paper sheet brittle, yellowing, will also make the color paper sheet warp and deformation. Pillows should also be added to the bottom of the stack, if the ground is wet and unleveled, this will prevent the color paper sheet from getting wet and dirty.
Similarly, it is important to note that the storage of color paper sheet does not allow the storage of chemicals or high content of water and grease goods. It is best to pile up all kinds of color paper sheet positions are basically fixed, to avoid unnecessary trouble. Dry winter and spring, wet summer and poor ventilation, light exposure will more or less affect the quality and performance of color paper sheet. So the temperature and humidity should be controlled well. Open-air cargo yard should not be suitable for storing color paper sheet, but for some reason need open storage of color paper sheet, the custody must be done well. Storage of color paper sheet to choose a dry, clean surrounding environment. No smoking should be allowed in the place where the color paper sheet is stored, and no electricity with open fire shall be used. Have. To have good fire control equipment and fire prevention measures, strictly prevent fire. Improve the storage environment of color paper sheet, can make color paper sheet better storage.

1. First we covered paper with oil pastel drawings until the entire sheet was full of color. 2. Then we painted over the oil pastel with a layer of black BioColor paint. 3. Finally, we scratched our pictures and designs through the surface of the wet paint with toothpicks and Q-tips. What makes this scratch art process easier than most… We used oil pastels rather than crayons and scratched our design through the wet paint which was both easier and quicker than if we had waited for the paint to dry. Paper size: Smaller sheets of paper will be quicker to fill with color. I cut our color paper in half, but you could go even smaller. Age: It’s important to fill the entire sheet with color, so this project works better with preschoolers on up who can/will do that. For toddlers, you can make the magic scratch paper for them and let them do the final step of scratching designs in the paper.
Oil pastels vs crayons: You can also use crayons, but oil pastels are easier and quicker, especially for younger kids.
Q-tips and toothpicks: We started with Q-tips in the wet paint for a wider line. Maia preferred the toothpicks…and Daphne liked to use both the Q-tips and toothpicks together. Wet vs dry: We made our scratch art pictures and designs while the paint was still wet and it worked great. We tried letting some dry first and found that the paint flaked off more unevenly (see the lines I did at the left of the face above). Paint type: The BioColor paint we used needed two layers to coat the oil pastel layer perfectly. We didn’t usually do two layers though and liked it fine with a bit of color peaking through. You can add a couple drops of liquid dish soap to make it coat the oil pastels more evenly although we didn’t at the beginning. We also tried acrylics, which coated better than the BioColor, and tempera paint. We tested tempera paint vs BioColor paint with and without dish soap and did all the scratch art designs after the paint dried. The three at the top were made with tempera paint and Daphne did the scratch art, which as you can see is barely visible. The three at the bottom were made with BioColor paint and Maia did the scratch art. I recommend giving this DIY scratch art activity a try with your kids! |
