It is primarily made from cellulose, and when it is plowed into the soil after harvesting, it decomposes in the soil, eliminating the burden of stripping work and waste disposal costs. Furthermore, while crops are growing, it can suppress the rise in soil temperature compared to polyethylene mulch sheets (according to our research). This has the effect of reducing root rot in crops caused by heat, making it particularly suitable for crops grown in the summer.

The web is formed using the airlaid method, which disperses pulp fibers and other materials in the air rather than in water. This allows for the creation of a bulky web. While maintaining the bulkiness of the web, a water-based adhesive (binder) is uniformly sprayed using a unique method, and after a drying process, it is turned into sheets. The binder can be selected based on its application, considering factors such as food compatibility and strength. Products include "Kinocross," which is made from wood pulp as the main raw material; "Palkross," which has a layer of low-weight rayon fibers on the surface of Kinocross; "Haikross," which incorporates synthetic fibers; and "B-SAP," which contains polymer absorbents. It is also characterized by the ability to color in relatively small lots. Ipros introduces processed products based on "Kinocross," "Palkross," and "Haikross." *For more details, please visit the official website http://www.kinocloth.co.jp. *Some TDS non-woven fabrics, such as "Soft Sheet," are also included.

The self-repairing waterproof sheet for leak prevention can be utilized as an absorption layer of the self-repairing waterproof sheet. If there is only a waterproof layer, any damage that causes a hole can lead to leaks; however, the high water-absorbent resin (fiber) incorporated into the sheet absorbs water and swells to seal the hole, preventing leaks. It can be used in waterproof civil engineering works such as final disposal sites, agricultural reservoirs, river embankments, and retention basins. As an absorption layer of the self-repairing waterproof sheet, it is common to have a bentonite layer sandwiched between the non-woven fabric of the surface material and the backing material. The disadvantage is that the sheet is very heavy, requiring large machinery for installation. Comparison with bentonite-based sheets: ◆ Work is made easier! A significant weight reduction of 25% improves workability! Large machinery is unnecessary, and the lightweight nature makes handling easy. ◆ Work efficiency is improved! The roll length is up to about five times longer, enhancing workability! The sheet is highly flexible and easy to handle, and the significantly increased roll length improves work efficiency. Features of the self-repairing waterproof sheet for leak prevention: - It has excellent waterproofing properties. - Even if sharp objects penetrate the sheet, it self-repairs and is less likely to leak. - It is lightweight and has excellent workability.

The anti-rust paper from Prince Eftex is a paper that is impregnated with a volatile anti-rust agent. When the target metal is wrapped in this anti-rust paper, the volatile anti-rust agent contained in the paper vaporizes, gradually filling the surrounding area and exerting an anti-rust effect on the surface of the target metal. The more tightly it is sealed after wrapping, the more effective it is. Additionally, there are various types of anti-rust paper available for different applications. Please select the appropriate anti-rust paper. 【Types】 - Ferrobite: For iron - Ferrobite SS: For iron, non-ferrous metals, and plated items - Cubelite: For copper - Cubelite DR8: For steel plates
