Abstract

A method of preparing a sterilized nonwoven web, which method includes providing a nonwoven web; coating the nonwoven web with from about 0.005 to about 3 percent by weight, based on the weight of the web, of an antistatic agent; and exposing the coated nonwoven web to an oxidizing gas plasma. The antistatic agent is adapted to be free of a malodor after exposure of the coated nonwoven web to the oxidizing gas plasma. The antistatic agent may be further adapted to provide a sterilized nonwoven web having a hydrohead value as measured by Method 5514 of Federal Test Method Standard No. 191A which is at least 50 percent of the hydrohead value of the coated nonwoven web before exposure to the oxidizing gas plasma. The antistatic agent also may be adapted to provide a sterilized nonwoven web having a surface resistivity in ohms which is lower than the surface resistivity in ohms of the coated nonwoven web before exposure of the coated nonwoven web to the oxidizing gas plasma. The antistatic agent may be an alkali metal or ammonium salt of either a mono- or di-C3-alkyl moiety is an alkyl group containing three carbon atoms optionally substituted with hydroxy groups or a <beta>-carbon substituted alkyl phosphate, a di(<beta>-carbon substituted alkyl) phosphate, or a mixture of two or more of foregoing. The invention also provides a fibrous sheet-like material, such as a barrier fabric, a sterilization wrap, a surgical garment, and medical procedure packs.

An application was filed on November 21, 1997, and a provisional application number 60 / 〇63,878 was filed on October 31, 1997, and this application is incorporated herein by reference. Liming Back This invention relates to sterilized nonwovens. More particularly, the invention relates to sterilized packages. The sterilized package is a liquid-impervious and microorganism-impermeable barrier material. The sterilization spoon wrap is usually made in rolls, and then converted into various sizes, such as cutting sheets required by hospitals, clinics, and other health care providers. In order to reduce or prevent the generation of static electricity during manufacturing and / or converting processes, an antistatic agent is usually applied early in the manufacturing process: in a package. Generally, antistatic agents are dissolved or dispersed in water, and the resulting water-like medium can be applied to the fabric by any suitable process. For example, water-like media can be applied by spray brushing, or by dipping and milking. Antistatic agents appearing on sterilized packages are also interesting during the packaging process. Bacterial reduction items are like surgical instruments, which are usually placed in a two-device shipping tray and the combination of the instrument and the shallow tray is wrapped. For example, the two-layer sterilization package and the top layer are bonded to Provide a sealed relationship. So the 'first-package' will end before the second package is applied. This process is the continuous packaging referred to for this technology. The electrostatic charge appearing on the sheet can be

Iron, while simultaneous packaging may be used, and when more than one layer of sheets are wrapped at the same time. In any case This package is designed to allow sterilizing agents such as steam or ethylene oxide to pass through in the presence of a barrier barrier in the population of microorganisms such as bacteria once the sterilization process has been completed. The contents of the package can be sterilized. Antistatic agents are, of course, well known in this technical field. One commercially available antistatic agent that has been commonly used in the past is butyl phosphate dipotassium and dibutyl potassium phosphate.

If the special term "antistatic agent" used here refers to σ 疋 one material = two or more When a mixture of materials is added to the fiber surface of a non-woven fabric, it will help dissipate the static charge from the fiber surface. Therefore, the electrostatic agent will increase the electrical conductivity of the fiber, and then increase the electrical property of the fiber. The term "coating" as used herein refers to the coating of the surface of a fiber or film with an antistatic agent and / or placing the antistatic agent in the S gap between fibers and fibers and / or At the bonding point. Not all applications must coat all fibers that make up the nonwoven. In order to add antistatic properties to the nonwoven, it is sufficient to coat only the fibers that make up the surface of the fabric. The term, "alkali metal" refers to the members of Group IA of the periodic table, such as lithium, sodium, potassium, rubidium, and cesium. The first three metals are often used. The special term "water head" refers to Federal Standard Test method 5514 The 値 measured at 19 1A. The water head 公布 announced here is in units of Newtons per square meter. As used herein, "surface resistivity number" means the method according to the AATCC test 76 : 1972 (see also U.S. Patent No. 4,041,203) Surface resistivity measured. This resistivity is expressed in ohms per square inch, or simply in ohms per square.

35 408011 λ7 _ _B7 V. Description of the invention (33) It is directly proportional to the added amount. The total increase of the water head with the antistatic agent F is significantly higher than that of the water head with the antistatic agent E. Based on the data in Table 9, the antistatic properties of both antistatic agent VIII and D are similar and exist within acceptable ranges. On the whole, in the study of the amount of addition, the characteristics of the electrostatic agents E and F are in the lowest acceptable range. If the trend observed at a higher level is to maintain a higher level of addition ', then the antistatic agents E and F at a higher level will have better results. Finally, all antistatic agents were studied as described in Example 2. After the treated fabrics were sterilized in the state of monoxide gaseous plasma, none of them produced malodor. Example 6 Using the antistatic agents A, D, E, and F, the process of Example 3 was repeated. It also includes a fifth antistatic agent, G. The antistatic agent g (TLF-8285, DuPont Chemicals, Wilmington, Delaware) was treated with a solution of approximately 50 weight percent dipotassium octyl phosphate and approximately equal gram molecular weight potassium dioctyl phosphate. The results are briefly described in Table 10.

Description of the invention (Table 35 The data in 10 states that 'in terms of water alone, The antistatic agent can reduce the surface tension of water to less than 72.103 Newtons per square meter (see Table 4). The antistatic agent G has the best performance in this respect; it is because The effectiveness of this material in reducing surface tension, even at low concentrations, and the rest, and this material is not included in the previously published examples of antistatic; in the end, this efficiency is not as good as the carbon replacement used in the present invention. The acetic acid moiety of the mono- and dibasic phosphonium salt is eager to have less than 7 carbon atoms. Antistatic agent D is roughly compared with antistatic agent A to reduce the surface tension of each other. Electrostatic agent A-as many water heads (see Table 8): Although antistatic agents E and F show the ability to reduce surface tension, this efficiency seems to be independent of the concentration in solution; for antistatic agent E, T is more Although the description is described in detail with specific embodiments, for those skilled in this technical field, after knowing the previous disclosure, it should be easy to find out the modifications, changes, and Its equivalent. Therefore, this The scope of the invention should be analyzed and evaluated with the attached patent application park and any equivalents. ---------- Packing — — I —: Ordering (please read the note on the back first and then write this page).
