With the development of science and technology and the increasing maturity of production technology, my country has developed rapidly in three-layer and five-layer composite materials, and its application scope is becoming more and more extensive. Today we will learn about this material.
During World War II, the U.S. military department used a very thick and dense fabric to make military uniforms in order to adapt to the combat conditions at that time.
This kind of fabric is woven from extremely fine Pima mercerized cotton, and then uses a fluorine-containing finishing agent combined with pyridine quaternary ammonium salt or melamine hydrophobic material for waterproof treatment. It has excellent water-repellent effect and is fully adapted to the needs of the time. needs.
After the war, this water-repellent fabric was very marketable and began to be used in the production of surgical gowns.
The three-layer and five-layer composite materials have a microporous structure with staggered fibers. The porosity can reach 80%~90%. After high-temperature heat setting treatment, the microporous structure is stable and can effectively intercept dust particles, and its pore size is Small and uniform, surface filtration mechanism, easy to remove dust, strong hydrophobicity, low surface energy, good non-adhesive ability, effectively remove dust accumulated on the surface, wash with water or backflush to restore performance, greatly extend service life, filtration efficiency can be Up to 99.9995%.
Suzhou New Material Technology Co., Ltd. is a manufacturer specializing in the research, development and production of three-layer and five-layer composite materials. After years of painstaking research and development, the company not only has strong R&D strength, complete testing methods and domestic advanced It has advanced experimental equipment and attracted a large number of outstanding technical talents.
