Definitions
- the present invention relates to the field of fabrics and, particularly, to articles which are absorbent to liquids, yet not completely permeable to liquids.
- carded stock is often chemically bonded into fabrics. Such carded webs are treated with adhesives or bonding agents and are then calendared to form "paper-light” materials. Carded webs have recently been replaced by thermobond materials, which have a softer "hand,” but which have reduced cross-directional strength.
- Non-wovens of this class such as SONTARA® by Du Pont, are widely accepted for use in medical gowns and drapes.
- An average hospital patient produces 55 lbs. of medical waste per day. Approximately 20 % of that waste is classified as "infectious.”
- the American Hospital Association and the Centers for Disease Control recommend immediate disposal of medical waste. Medical waste is considered an occupational hazard for health care workers, but is not considered an environmental safety problem.
- the most preferable way to contain infectious medical waste is to disinfect it at the point of generation and dispose of the treated medical waste with minimum handling and storage on premises.
- the invention herein solves the drawbacks of the prior art by providing a textile suitable for use in the medical environment, such as for use as a gown or a drape, which is capable of absorbing harmful liquids yet preventing contact of the liquids with a patient or worker.
- the invention in another embodiment, provides such a textile which can be disposed of without additional risk of contamination or reinfection.
- the invention provides a textile disposal process that does not require the article to be introduced to a landfill, where it would be environmentally detrimental as well as potentially infectious.
- the invention also provides an alternative textile in which these desirable capabilities are provided for in a unitary, i.e., one piece, non- laminated article.
- the present invention provides an article comprising a fabric layer permeable to a first liquid and having a first side and an opposed second side, wherein the first side of the fabric layer further comprises a coating repellent to the first liquid, wherein the coating substantially penetrates into the first side of the fabric layer, thereby forming a first liquid proof first side.
- the fabric layer is soluble in a second liquid when the second liquid is hot and insoluble in the second liquid when the second liquid is cold.
- the article is a surgical fabric.
- the article is a surgical drape.
- the fabric layer dissolves in the second liquid only at a temperature above 37 °C.
- the article further comprises a plastic layer having a first side and an opposed second side, wherein the first side of the plastic layer faces the first side of the fabric layer.
- the present invention provides an article comprising a first fabric layer permeable to a first liquid and having a first side and an opposed second side, wherein the first side of the first fabric layer further comprises a coating repellent to the first liquid, wherein the coating substantially penetrates into the first side of the first fabric layer, thereby forming a first liquid proof first side of the first fabric layer, and a second fabric layer permeable to the first liquid and having a first side and an opposed second side, wherein the first side of the second fabric layer further comprises a coating repellent to the first liquid, wherein the coating substantially penetrates into the first side of the second fabric layer, thereby forming a first liquid proof first side of the second fabric layer, whereby the first liquid proof first side of the first fabric layer faces the first liquid proof first side of the second fabric layer.
- first and second fabric layers are soluble in a second liquid when the second liquid is hot and insoluble in the second liquid when the second liquid is cold.
- the article is a surgical fabric.
- the article is a surgical drape.
- the fabric layer dissolves in the second liquid only at a temperature above 37 °C.
- At least one plastic layer is disposed between the first liquid proof side of the first fabric layer and the first liquid proof side of the second fabric layer.
- the first and second fabric layers are soluble in a second liquid when the second liquid is hot and insoluble in the second liquid when the second liquid is cold.
- the present invention provides a method of disposing of the articles of the invention, wherein the fabric layer is soluble in a second liquid when the second liquid is hot and insoluble in the second liquid when the second liquid is cold, comprising contacting the article with a sufficiently hot second liquid for a sufficient period of time to disperse or dissolve substantially the article.
- FIG 1 shows one embodiment of the present invention.
- FIG. 2 shows another embodiment of the present invention.
- FIG. 3 shows another embodiment of the present invention.
- FIG. 4 shows another embodiment of the present invention.
- fabric layer refers to a woven or non-woven fabric material suitable for producing textile-like articles.
- One or more layers of the fabric may comprise a "fabric layer”.
- permeable refers to the ability of a particular article or item to permit fluids, such as liquids, to pass therethrough or to penetrate therein.
- liquid refers to fluids such as water, blood, and urine.
- coating refers to a distinct portion of a surface having the stated properties.
- the “coating” may be contiguous with the substrate or may comprise a separate layer affixed thereto.
- repellent when used in connection with a coating, describes the ability of the coating to resist, at least partially, permeation or penetration by the specified fluid. Hence, a “water repellent” article resists water from permeating the article.
- the term “substantially penetrates” refers to the extent to which the stated material has integrated into the specified substrate. Substantial penetration, as used herein, involves a penetration into the item of from about 10 to about 90 %, more preferably 20 to 80 %, most preferably about 50 % of the thickness of the item. As used herein, the term “dispersable” refers to an item which may or may not dissolve completely in the stated fluid, such as a liquid, but does structurally fragment or break apart in the presence of the fluid.
- hot is used to refer to temperatures above about body temperature, or 37 °C. More preferably, “hot” refers to temperatures above 40 °C, more preferably to temperatures above 45 °C, even more preferably to temperatures above 50 °C, even more preferably to temperatures above 75 °C, and most preferably to temperatures above 90 °C.
- cold is used to refer to temperatures below about body temperature, or 37 °C. More preferably, “cold” refers to temperatures below 30 °C, more preferably to temperatures below 25 °C, and even more preferably to temperatures below 20 °C.
- surgical fabric refers to a textile like woven or non- woven article suitable for use in an operating room. Such fabrics include, but are not limited to gowns, drapes, and masks. Thus, a "surgical drape” is one type of "surgical fabric.”
- operating aperture refers to an opening cut through one of the articles of the invention so as to permit a surgical or other procedure to be performed through the opening.
- face As used herein with respect to various layers of the article, the terms “face”, “facing” and “faces” refer to two or more layers that are positioned adjacent to one another with the indicated sides directed toward one another. Facing layers need not be in contact and may, optionally, have further matter disposed therebetween.

- the first side of the first fabric layer is further coated with a coating repellent to the first liquid.
- the coating substantially penetrates into the first side of the first fabric layer.
- the coated, penetrated first fabric layer thereby forms a first liquid proof first side of the first fabric layer.
- the article also comprises a second fabric layer permeable to the first liquid and having a first side and an opposed second side.
- the first side of the second fabric layer also has a coating repellent to the first liquid placed thereon. This coating also substantially penetrates into the first side of the second fabric layer and forms a first liquid proof first side of the second fabric layer.
- the article is formed such that the first liquid proof first side of the first fabric layer faces the first liquid proof first side of the second fabric layer.
- a particularly preferable article is formed such that the article can absorb contaminants emanating from the environment and from the patient or wearer, yet the article is capable of preventing the contaminants from passing through the article and becoming a further hazard.
- the first and second fabric layers are soluble in a second liquid when the second liquid is hot and insoluble in the second liquid when the second liquid is cold.
- the first liquid is water.
- the second liquid is water.
- the article is a surgical fabric, such as a surgical drape.
- the fabric layer of the drape has a portion cut therefrom, thereby defining an operating aperture of the drape.
- the article also has at least one plastic layer disposed between the first liquid proof side of the first fabric layer and the first liquid proof side of the second fabric layer.
- the plastic layer may be comprised of a single layer of plastic, or, alternatively, may be comprised of two or more plastic layers adjacent to one another.
- the article could be made from two of the articles of Figure 1, joined at their plastic layer sides.
- the "total thickness" of the at least one plastic layer refers to the cumulative thickness of all of the plastic layers.

- the first liquid is water, saline, blood, urine, surgical irrigation fluid runoff, alcohol solutions, other bodily fluids, or the like.
- the coating repellent to the liquid is a portion of the fabric that has been treated with a liquid repellent.
- the liquid to be repelled is water or, at least, aqueous
- the water repellent can be any typical water repellent known in the art.
- the water repellent is applied to the fabric on the underside of the fabric, i.e. the side that is placed in contact with the body of the patient. That is, the waterproof layer faces toward the patient's body.
- the article is also absorbent and repellent to alcohol.
- the water repellent is applied to only one side, thereby creating a fabric having an absorbent side and a water repellent side opposite the absorbent side. Complete penetration of the repellent into the fabric layer would preclude the article from having a fluid absorbent side. Therefore, the repellent should substantially, but not completely, penetrate the fabric layer. Penetration is preferably from 10 to 90 % of the thickness of the layer, more preferably from 20 to 80 %, even more preferably 40 to 60 % of the thickness, and most preferably about 50 % of the thickness of the layer.
- Disposal of the articles of the invention is accomplished by dissolution at the proper temperature in the second liquid.
- the second liquid is water.
- other solvents may be used and materials may be chosen so that the articles are disposable as described herein.
- preferred articles include surgical fabrics and surgical drapes.

- the fabric comprises poly(vinyl) alcohol.
- the poly( vinyl) alcohol is a greater than 95% saponified poly vinyl acetate, more preferably greater than 98% saponified poly vinyl acetate, even more preferably greater than 99% saponified poly vinyl acetate, and even more preferably is greater than 99.99% saponified poly vinyl acetate.
- the fabric layer is an absorbent material so that the liquid can be absorbed quickly without spillage onto the patient's body. Suitable hot liquid soluble, cold liquid insoluble materials, such as poly vinyl alcohol materials, are described in detail in U.S. Patents No. 5,181,966, 5,181,967, and 5,207,837, the contents of which are hereby incorporated by this reference. Other suitable materials for forming the fabric have been listed above with respect to the plastic layer.
- the present invention also provides a disposal method applicable to the articles.
- the present invention provides a method of disposing of the articles of the invention, especially where the fabric layer is soluble in a second liquid when the second liquid is hot and insoluble in the second liquid when the second liquid is cold.
