113 results about "Product substitution" patented technology

In consumer theory, substitute goods or substitutes are products that a consumer perceives as similar or comparable, so that having more of one product makes them desire less of the other product. Formally, X and Y are substitutes if, when the price of X rises, the demand for Y rises.

High-permeable medical adhesive tape base material and preparation method thereof

The invention discloses a high-permeable medical adhesive tape base material and a preparation method thereof. The adhesive tape base material comprises wood pulp fibers, polyester fibers, low meltingfibers, AKD neutral sizing liquid and wet strength agent liquid. The preparation method comprises a pulping step, a papermaking step, a drying step and a reeling step. In the pulping step, the AKD neutral sizing liquid and the wet strength agent liquid are added to a pulping pool and uniformly mixed. The high-permeable medical adhesive tape base material is prepared by mixing and pulping treatment of pure plant fibers and synthetic fibers through papermaking of a papermaking machine, and has the advantages of softness and loosening, homogeneous fibers, high air permeability, strong wrinkle resistance, easy-tearing while a product meets strength, uniform gluing and the like. The high-permeable medical adhesive tape base material is directly formed through adhesion between the fibers and melted adhesion without surface gluing reinforcement treatment, simple in processing technology, and low in manufacturing cost, and is a substitute good of a current medical cloth-based base material and a punching PE base material. Along with continuous improvement of human health requirements, a demand gap is large, and market prospect is extremely extensive.
