Problems solved by technology

The surgical gowns and surgical cloths currently in use are made of cotton, which can be washed and disinfected for repeated use, and do not have the function of blocking blood, body fluids and bacteria, so it is difficult to meet the promulgated health protection standards
Although the currently commonly used disposable medical products can play a certain protective role, they cannot be reused, and there are many wastes, which increase the cost in the economy, and increase the cost in terms of the environment.

Abstract

The invention relates to a plus material capable of being repeatedly used and realizing good performance of shielding liquid such as water, blood, body fluid and the like, moisture permeability, good ventilation performance and the like, and a manufacture process of the plus material, in particular to a plus material for medical operation garments and cloth for operation. The plus material comprises a surface layer, an inner layer and a middle protection layer poly urethane (PU) film, wherein the surface layer and the inner layer are textile fabrics with proper density and tissue structures. The plus material is characterized in that the plus material is made by pasting the surface layer, the protection layer and the inner layer by hot melt adhesives. The manufacture process of the plus material is simple, products are used for the medical operation garments and the cloth for operation, have the moisture permeability and ventilation performance and also have good functions of shielding liquid such as water, blood, body fluid and the like, the washing resistance is good, the plus material can be repeatedly used for many times, the medical high-temperature sterilization processing resistance can also be realized, the service life is long, and the plus material still has good waterproof and ventilation performance, good blocking performance and high bonding intensity after being subjected to 80 times of washing, baking and sterilization treatment.

Description

technical field [0001] The invention relates to a fabric for medical surgical gowns and surgical cloths, in particular to a reusable fabric with excellent properties of shielding water, blood, body fluids and other liquids, as well as moisture permeability and air permeability, and its manufacturing process. Background technique [0002] The development of medicine provides better protection for human health. In my country, tens of millions of surgical operations are performed every year, and the number is increasing. Some of them were accompanied by nosocomial infection, resulting in the death of the patient. About 25% of all postoperative infections are induced by traumatic infections in the operating room, and the common causes of infection are exposure to dust pollution or pollution of dusty air on the surfaces of surgeons, patients and pathogens. Surgical gowns and drapes can protect medical staff and patients, effectively blocking bacteria, dust particles and liquids...
