Medical microporous breathable skin color cloth and application thereof
Technical Field
The invention relates to the technical field of textiles, in particular to a medical microporous breathable skin color cloth.
Background
With the development of modern textile technology, textiles almost extend into various fields of human life, and medical textiles are taken as a branch of textiles, are a new field formed by combining textile technology and medical science, and are one of varieties with strongest creativity and highest technological content in the textiles. The medical field has higher requirements for textiles. At present, medical textiles become a high value-added product which integrates the interdisciplinary disciplines of textile, medicine, biology, high polymer and the like and is fused with high technology.
In view of the particularity of the medical textile, the performance requirements on the medical textile are very high. The most basic requirements are that the disinfectant is nontoxic and harmless, cannot cause cancer, has no bad stimulation, cannot cause allergy, cannot generate toxic or harmful substances by the action with human tissues or secretion, can be subjected to conventional sanitary disinfection treatment, and can keep stable performance under certain hot and humid conditions. For medical textiles in direct contact with skin, such as wound dressing cloth or plaster cloth, it is required to have good air permeability and moisture permeability, and good antibacterial property. The existing adhesive bandage cloth or plaster cloth is generally made of non-woven fabrics. However, after the non-woven fabric product in the prior art is in contact with skin for a long time, the problems of difficult healing of skin wounds, skin allergy damage and the like can be caused due to poor air permeability and moisture permeability, and the non-woven fabric product does not have an antibacterial function and easily causes wound reinfection.
