Problems solved by technology

However, generally these additive components will migrate to the surface of the film material, which will definitely contaminate the medical devices in contact with it, and even cause wound infection of the patient.
In addition, even if these opening additives and slippery additives are added to the Meishi sleeves on the market, it cannot solve the problem of Meiji sleeve movement caused by poor opening and high friction.

Abstract

The invention relates to a thin film with granular handfeel, a composite material and an application. The thin film has a structure with one layer or more, wherein the raw material formula of at least one structure of any one layer of the thin film comprises ultrahigh molecular weight polymer particles which have a diameter in a range of 10 [mu]m to 500 [mu]m, a molecular weight in a range of 1 million to 7 million and a melting point in a range of 125 DEG C to 180 DEG C. According to the invention, the ultrahigh molecular weight polymer particles are added into the raw material formula of the thin film, so the surface of the thin film achieves the bulging effect with the granular handfeel; meanwhile, the thin film provided by the invention has the advantages of easy opening, low friction coefficient and no additive migration problem. The thin film provided by the invention enables the space between the thin film and a fiber material to be enlarged due to uneven bulges on the surface of the thin film, so the composite material provided by the invention has higher water absorption multiplying power and higher water-absorbing capacity.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, is applied in the medical and health industry, and relates to a film with a grainy feel, a preparation method thereof, and a composite material obtained by compounding the film with fiber materials and the like. Background technique [0002] In the operating room of a hospital, a mayo stand (commonly referred to as a tray) is a stainless steel frame used to place surgical instruments, trays, drugs and other surgical supplies. The Mayo stand generally consists of a larger stainless steel tray and C Composed of a stand with pulleys. When using the mayo stand cover, a mayo stand cover (usually called a surgical tray cover) should be put on the outside to prevent cross-infection, and it can also be used to collect medical waste after the operation. The Meishi sleeve is generally made of polyolefin film and fiber fabric, one end is closed and the other end is open. [0003] The open end of th...
