Description
- The present application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/555,581 filed on Nov. 4, 2011 entitled FABRIC FOR BED SHEET, the disclosure of which is incorporated herein by reference in its entirety.
- The present invention relates to fabric material, and, more particularly, to fabric material having antimicrobial and healing properties, as well as a low coefficient of friction.
- Products made from fabric materials, such as bed sheets and pillow cases used in hospitals, nursing homes and rehabilitation centers, are a potential source of bacterial colonization, skin irritation, and migration or worsening of skin infections. Bed sheets and pillow cases often produce irritated areas on a patient's skin as a result of friction caused by motion or lack of motion of the patient relative to the bed sheets and pillow cases. This skin irritation contributes to the formation of pressure ulcers. What is needed is a fabric material having antimicrobial properties, a low coefficient of friction, a “cool to the touch” feel, and moisture-wicking properties.
- In an embodiment, a fabric material including a plurality of strands of a warp yarn positioned in a warp direction; a plurality of strands of a first filling yarn positioned in a filling direction, each of the plurality of strands of the first filling yarn being impregnated by silver ions; and a plurality of strands of a second filling yarn positioned in the filling direction each of the plurality of strands of the second filling yarn being impregnated by copper ions, wherein the plurality of strands of the warp yarn are woven with the plurality of strands of the first filling yarn and the plurality of strands of the second filling yarn to form a face side and a back side opposite the face side, and wherein each of the plurality of stands of the first filling yarn and each of the plurality of strands of the second filling yarn are woven alternately relative to one another with the plurality of strands of the warp yarn in the filling direction.
- In an embodiment, the fabric material includes a five-harness satin weave pattern. In an embodiment, the five-harness satin weave pattern is characterized by two of the plurality of strands of the first filling yarn and two of the plurality of strands of the second filling yarn floating over four of the plurality of strands of the warp yarn on the face side. In an embodiment, the five-harness satin weave pattern is characterized by four strands of the plurality of strands of the warp yarn underlying two strands of the plurality of strands of the first filling yarn and two strands of the plurality of strands of the second filling yarn on the back side. In an embodiment, the coefficient of friction of the face side in the filling direction is less than the coefficient of friction of the back side in the filling direction. In an embodiment, the plurality of strands of the warp yarn are made of filament rayon. In an embodiment, the plurality of strands of the first filling yarn are made from PLA polymer, and the plurality of strands of the second filling yarn are made from PLA polymer. In an embodiment, the fabric material is antimicrobial, cool to the touch, and wickable. In all embodiment, the plurality of strands of the first filling yarn are made from nylon, and the plurality of strands of the second filling yarn are made from nylon. In an embodiment, the plurality of strands of the first filling yarn are made from polyester, and the plurality of strands of the second filling yarn are made from polyester.
- In an embodiment, the fabric material is adapted to be used as a bed sheet. In an embodiment, the fabric material includes a plain weave pattern. In an embodiment, the plain weave pattern is characterized by five strands of the plurality of strands of the warp yarn in the warp direction, and five alternating strands of the plurality of strands of the first filling yarn and the plurality of strands of the second filling yarn in the filling direction, In an embodiment, the coefficient of friction of the face side is approximately equal to the coefficient of friction of the back side. In an embodiment, the fabric material is adapted to be used as a pillow case. In an embodiment, the fabric material includes a twill pattern.
- In an embodiment, a method for making a fabric material includes the steps of weaving a plurality of strands of a warp yarn in a warp direction with a plurality of strands of a first filling yarn impregnated with silver ions in a filling direction and a plurality of strands of a second filling yarn impregnated with copper ions in the filling direction, wherein each of the plurality of stands of the first filling yarn and each of the plurality of strands of the second filling yarn are alternately woven with the plurality of strands of the warp yarn in the filling direction; scouring the fabric material to remove external matter; conditioning the fabric material in order to soften it; drying the fabric material; and calendaring the fabric material to smoothen it. In an embodiment, the conditioning step includes wet processing the fabric material using a cationic softener,
- In an embodiment, the silver ion impregnated filling yarn and the copper ion impregnated filling yarn are manufactured separately and inserted alternately in the filling direction of the weave. In an embodiment, the silver and copper ions of the filling yarns provide antimicrobial and healing properties which are effective in combating the 2.5 growth and proliferation of harmful bacteria and fungus. With the silver and copper ions being inherently impregnated, they are resistant to being removed during repeated launderings of the fabric material, which enables the fabric's antimicrobial and healing properties to remain effective.
- In an embodiment, the weave of the fabric material provides a low coefficient of friction on the face-side of the fabric, which inhibits irritation of a user's skin. In an embodiment, the rayon used in the warp direction of the weave possesses a low coefficient of friction that reduces the level of friction experienced by a user (such as a patient on a bed sheet) when he/she moves from side-to-side relative to the fabric. The reduced level of friction inhibits the formation of skin abrasions, which is one of the causes of pressure ulcers. In an embodiment, the fabric material includes a higher coefficient of friction on the back-side thereof versus the coefficient of friction on the face-side thereof. The higher coefficient on the back-side inhibits movement of the fabric material during movement by the user, when he/she moves from side-to-side thereon, thus reducing formation of wrinkles and creases that causes irregularity in the fabric's surface and creates additional friction points for the user.
- In an embodiment, the fabric material is used for medical bed sheets, pillow cases, and other pressure ulcer related medical products. In an embodiment, the fabric material is absorbent and possesses a low coefficient of friction. In an embodiment, medical bed sheets that are fabricated from the fabric material provide patients comfort and pressure ulcer mitigation. Mitigation of patient pressure ulcers provides a benefit to the overall medical treatment and well being of the patient. In an embodiment, the low coefficient of friction on the face-side of the bed sheet greatly enhances rotation of disabled or sedentary patients by hospital staff. In an embodiment, the fabric material helps support a significantly enhanced ergonomic process in the hospital environment (e.g., it facilitates patient movement and rotations by hospital care giver staff). In an embodiment, the reduction in the required physical demands on care giver staff not only reduces lost time to injuries but also tends to increase the actual number of patient rotations completed by care givers. If patient rotations are easier to accomplish, care givers may be far more physically-able to complete timed rotations of the patients.
- In other embodiments, the fabric can be used in connection with wearing apparel, boots, elbow pads, and other contact point protection shields.

FIGS. 1 and 2 illustrate a portion of afabric material 10 constructed in accordance with an embodiment of the present invention. In embodiments to be described hereinbelow, thefabric material 10 is made from a plain weave, a twill weave, or a satin weave. In an embodiment, thefabric material 10 includes a face-side 12 and a back-side 14 opposite the face-side 12 (seeFIG. 2 ). In an embodiment, thefabric material 10 is woven in a five-harness filling satin weave construction.FIG. 1 illustrates the face-side 12 of thefabric material 10, which shows one of a repeating pattern of a plurality of strands ofwarp yarn 16 which are provided in a warp direction, as indicated by arrows W, and one of a repeating pattern of a plurality of alternating strands offilling yarn 18 and fillingyarn 20, which are provided in the filling or weft direction, as indicated by arrows F. In an embodiment, the repeating pattern of the plurality of strands of thewarp yarn 16 is five (5) strands, as shown inFIGS. 1 and 2 . In an embodiment, the repeating pattern of the plurality of alternating strands of thefilling yarns FIG. 1 . In an embodiment, thewarp yarn 16 is made of filament rayon. In an embodiment, the filament rayon comprises ENKA® filament rayon. In an embodiment, the filament rayon has a low coefficient of friction, absorbency, wicking, and “cool to the touch” properties, and mitigates static electricity. In other embodiments, the filament rayon can be made by other manufacturers. - In an embodiment, the strands of the filling
yarn 18 are made from a PLA (polylactic acid) polymer, nylon or a polyester yarn base that is inherently impregnated with silver ions (i.e., impregnated substantially equally throughout the entire yarn), while the strands of fillingyarn 20 provided in the filling direction F are made from a PLA polymer, nylon or a polyester yarn base that is inherently impregnated with copper ions. In an embodiment, the PLA polymer is manufactured by Radici Fibers. In other embodiments, the PLA polymer can be made by other manufacturers. In an embodiment, the strands of the fillingyarns yarn 20 is inserted in one pick, alternating with the fillingyarn 18 in the next pick, and so on). In an embodiment, the silver and copper ions of the fillingyarns - In an embodiment, the filling
yarn 18 is fabricated from fibers having inherent silver ions added to the base material of the master batch (e.g., PLA polymer, nylon or polyester yarn) of the fiber slurry in a process such as that disclosed in International Patent Publication Number WO 2006/084411 A1, published on Aug. 17, 2006 (the “'411 International Publication), which is incorporated by reference herein in its entirety. Upon extrusion of the fiber, the silver ions are inherently part of the fiber. Likewise, the fillingyarn 20 may be fabricated from fibers which have inherent copper ions added to the base material (e.g., PLA polymer, nylon or polyester yarn) of the master batch of the fiber slurry in the process disclosed in the '411 International Publication. Upon extrusion of the fiber, the copper ions are inherently part of the fiber. - In an embodiment,
FIG. 2 illustrates the surface contours of the face-side 12 and the back-side 14 of the five-harness filling satin weave construction of thefabric material 10. In an embodiment, an arrow L indicates one of a repeated area of surface contours on the face-side 12, which contributes to a coefficient of friction in the filling direction F that is lower than the coefficient of friction in the filling direction F on the back-side 14 of thefabric material 10. More particularly, in an embodiment, on the face-side 12 of the fabric, an arrow L indicates one of a repeated area of surface contours in which the two strands of the fillingyarn 18 and the two strands of the fillingyarn 20 float over (i.e., is not interwoven with) four strands of thewarp yarn 16, thereby minimizing the coefficient of friction on the face-side 12 in the filling direction F. In an embodiment, the rayon used in the warp direction W also contributes to the low coefficient of friction in the filling direction F. In an embodiment, on the back-side 14 of thefabric material 10, an arrow H indicates one of a repeated area of surface contours in which the four strands of thewarp yarn 16 underlie the two strands of the fillingyarn 18 and the two strands of the fillingyarn 20, thereby maximizing the coefficient of friction on the back-side 14 in the filling direction F. - In an embodiment, the
fabric 10 is woven in specific shapes and sizes to accommodate end use applications. For example, in an embodiment illustrated byFIG. 3 , a fittedbed sheet 22, which is made of thefabric material 10 and has fitted bottoms corners C, is shown fitted on abed mattress 24. In an embodiment, apillow 26 is also shown positioned on the fittedbed sheet 22. In an embodiment, themattress 24 has a length indicated by the arrow L, a breadth indicated by the arrow B, and a thickness indicted by the arrow T. In an embodiment, the coefficient of friction in the filling direction F of thefabric material 10 reduces the level of friction that is experienced by a person (e.g., a patient) when he/she moves from side-to-side or is rotated by care giver staff on the face-side 12 of the fittedbed sheet 22. In an embodiment, the reduced level of friction on the face-side 12 of thefabric material 10 inhibits the formation of skin abrasions on the skin of the person resting on the fittedbed sheet 22, which is one of the causes of pressure ulcers. In an embodiment, the higher coefficient of friction of the back-side 14 of the fittedbed sheet 22 in the filling direction F serves to inhibit movement of the fittedbed sheet 22 relative to themattress 24, limiting the formation of wrinkles, creases or other characteristics that cause irritation points. -
FIG. 4 depicts another embodiment of the present invention. Elements illustrated inFIG. 1 , which correspond, either identically or substantially, to the elements described above with respect to the embodiment illustrated byFIGS. 1 and 2 , have been designated by corresponding reference numerals increased by one hundred. Unless otherwise stated, the embodiment illustrated byFIG. 4 is constructed and assembled in the same basic manner as the embodiment illustrated byFIG. 4 . -
FIG. 4 illustrates a portion of afabric material 110 constructed in accordance with another embodiment of the present invention. In an embodiment, thefabric material 110 is woven in a plain weave construction. In an embodiment,FIG. 4 illustrates the face-side of the material 110 which shows a repeating pattern of five (5) strands ofwarp yarn 116 in a warp direction, as indicated by the arrows W, and a repeating pattern of five (5) strands of alternating fillingyarn 118 and fillingyarn 120 in a filling or weft direction, as indicated by arrows F. In an embodiment, the strands of the fillingyarn 116 provided in the warp W direction are made of filament rayon. In an embodiment, the strands of fillingyarn 118 are made from a PLA polymer, nylon or a polyester yarn base that are inherently impregnated with silver ions, while the strands of the fillingyarn 120 are made from PLA polymer, nylon or polyester yarn base that are inherently impregnated with copper ions and are alternately inserted in the filling direction F (i.e., the fillingyarn 120 is inserted in one pick, alternating with the fillingyarn 118 in the next pick, and so on). Alternatively, in another embodiment, polyester or nylon yarn may be used as the base in the fillingyarns - In an embodiment, the filling
yarn 118 is fabricated from fibers that have inherent silver ions added to the base material of the master batch (e.g., PLA polymer, nylon or polyester yarn) of the fiber slurry in a process such as that which is disclosed in the '411 International Publication. Upon extrusion of the fiber, the silver ions are inherently part of the fiber. Likewise, the fillingyarn 120 may be fabricated from fibers which have inherent copper ions added to the base material (e.g., PLA polymer, nylon or polyester yarn) of the master batch of the fiber slurry in the process disclosed in the '411 International Publication. Upon extrusion of the fiber, the copper ions are inherently part of the fiber. - In an embodiment, the
fabric material 110 may be fabricated into pillow cases for covering, for example, thepillow 26 shown inFIG. 3 , and a top sheet (not shown) for use with the fitted bedsheet fabric material fabric material 110 provides the same coefficient of friction on the face-side and the back-side. In an embodiment, the silver and copper ions of the fillingyarns fabric material 10. - It should be appreciated that the present invention provides numerous advantages over the prior art discussed above. For instance, the fitted
bed sheet 22 mitigates the formation of pressure ulcers and helps to heal existing pressure ulcers. More particularity, the fittedbed sheet 22 has a low coefficient of friction, and has antimicrobial agents that inhibit the development of micro-organisms, and has healing capabilities which are effective in reducing skin-born irritations. In an embodiment, the rayon used in the warp direction W possesses a low coefficient of friction and has significant absorption properties. In an embodiment, the absorption properties wick-away away moisture from the skin of the patient and contributes to the evaporation of moisture, which keeps the skin of the patient dry. This absorption prevents an environment conducive to bacterial growth and wicks odor-causing moisture from patients that are incontinent, In an embodiment, the rayon used in thewarp yarn 16 in the warp direction W also has a natural cool feeling to the touch. This, in addition to its moisture wicking-action, assists in keeping the overall body temperature of the patient as cool as possible while resting or sleeping on the fittedbed sheet 22. The fittedbed sheet 22 is also breathable and disposable at the end of its useful life. For instance, in an embodiment, if the fittedbed sheet 22 is constructed with rayon in the warp direction W, and PLA polymer, nylon or polyester yarn infused with copper and silver ions in the filling direction F, the material is 100% biodegradable. In another embodiment, if the fittedbed sheet 22 is constructed with rayon in the warp direction W and nylon or polyester infused with copper and silver ions in the filling direction F, it is compostable. - In an embodiment, silver ions, along with PLA polymer, nylon or polyester yarn, have antimicrobial properties which will inhibit the growth of bacteria on the surface of the fitted
bed sheet 22 as well as on the skin of the patient, thereby minimizing or eliminating bacterial growth which is a contributing factor to the formation of pressure ulcers. Copper ions are known to be a healing agent. The combination of the silver ions and copper ions in the fittedbed sheet 22 provides both antimicrobial and healing properties. Because, upon extrusion of the fiber, the silver ions are inherently part of the fiber of the fillingyarn 18, and the copper ions are part of the fiber of the filling yarn 20 (i.e., not just applied to their exterior surface), the antimicrobial and healing properties provided by the silver and copper ions will not wear away as the fittedbed sheet 22 is used and laundered over its useful life. - It should be noted that the present invention can have numerous modifications and variations. For instance, in an embodiment, the weave construction of the
fabric material 10 may be provided with a float in the filling direction F which is less than 4 strands ofwarp yarn 16. In an embodiment, the number of strands of the fillingyarn 18 in the filling direction F may be greater or less than the number of strands of the fillingyarn 20 in the filling direction F. In an embodiment, the strands in the filling direction may include only the fillingyarn 18. In an embodiment, the strands in the filling direction F may include only the fillingyarn 20. Examples of other weave construction that may be utilized in the fabric of the present invention (i.e., in addition to the 5-harness filling satin weave of thefabric material 10 and the plain weave of the material 110) are twill weaves and sateen weaves. In an embodiment, thefabric materials fabric materials fabrics fabric materials fabric materials - It will be understood that the embodiment described herein is merely exemplary and that a person skilled in the art may make many variations and modifications without departing from the spirit and scope of the invention. For instance, all such variations and modifications, including those described hereinabove, are intended to be included within the scope of the invention and as defined in the appended claims.
