Definitions

  • 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 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.
  • 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.
  • the fabric material includes a five-harness satin weave pattern.
  • 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.
  • 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.
  • 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.
  • the plurality of strands of the warp yarn are made of filament rayon.
  • 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.
  • the fabric material is antimicrobial, cool to the touch, and wickab!e.
  • 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.
  • 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.
  • the fabric material is adapted to be used as a bed sheet.
  • the fabric material includes a plain weave pattern.
  • 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.
  • the coefficient of friction of the face side is approximately equal to the coefficient of friction of the back side.
  • the fabric material is adapted to be used as a pillow case.
  • the fabric material includes a twill pattern.
  • a method for making a fabric materia! 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.
  • the conditioning step includes wet processing the fabric material using a cationic softener.
  • 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.
  • the silver and copper ions of the filling yarns provide antimicrobial and healing properties which are effective in combating the 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.
  • 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.
  • 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.
  • 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.
  • the fabric material is used for medical bed sheets, pillow cases, and other pressure ulcer related medical products.
  • the fabric material is absorbent and possesses a low coefficient of friction
  • 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.
  • the low coefficient of friction on the face-side of the bed sheet greatly enhances rotation of disabled or sedentary patients by hospital staff.
  • 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).
  • 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.
  • the fabric can be used in connection with wearing apparel, boots, eibow pads, and other contact point protection shields.
