Definitions

  • the invention relates to the use of lyocell fibers, a yarn containing lyocell fibers, a textile fabric containing lyocell fibers, and a textile article containing lyocell fibers.
  • lyocell has been assigned by BISFA (The International Bureau for the Standardization of Man Made Fibers) and stands for cellulose fibers which are produced from solutions of cellulose in an organic solvent, tertiary amine oxides, in particular N-methyl Morpholine N-oxide (NMMO) is used, for example, a process for producing lyocell fibers is described in US-A 4,246,221.
  • BISFA The International Bureau for the Standardization of Man Made Fibers
  • NMMO N-methyl Morpholine N-oxide
  • the present invention relates to the use of lyocell fibers in wound treatment products.
  • the expert generally distinguishes three phases of physiological wound healing:
  • the primary goal of the treatment is the elimination of cell debris and microorganisms as well as the formation of a provisional matrix
  • the primary target is to form granulation tissue and reepithelialize to form a temporary barrier
  • the present invention is a dry wound treatment product which is currently primarily cotton
  • essentially untreated products such as bleached cotton
  • the quickest way to heal wounds would be theoretically (in a germ-free, moist environment) without any support from a bandage, etc.
  • WO 2005/026424 A1 describes the use of lyocell fibers for the treatment of textile contact sensitivity or skin diseases, in particular xerosis, atopic eczema or psoriasis.
  • Austrian Patent Application A 1471/2008 describes chitosan-modified cellulose fibers and their use as wound-healing products.
  • significantly more proliferative cells were wound on the wound edge and tendentially more proliferative cells in the regenerating epidermis of chitosan-treated lyocell fibers than untreated lyocell fiber and cotton.
  • DE 100 07 794 A1, DE 100 37 983 A1 and EP 1 354 914 describe polymer compositions which each comprise a biodegradable polymer and various modifying agents, e.g. Including algae, alkaloids and herbs.
  • the polymer composition may be in the form of fibers, e.g. from a mixture of the modifying agent with a solution of cellulose in a tertiary amine oxide.
  • non-modified lyocell fibers ie lyocell fibers that do not have modifying agents such as chitosan, algae, alkaloids carboxymethylated form
  • modifying agents such as chitosan, algae, alkaloids carboxymethylated form
  • the present invention relates to unmodified lyocell fibers, a yarn containing unmodified lyocell fibers, a fabric containing unmodified lyocell fibers, or a textile article containing unmodified lyocell fibers, each for specific use as a product for wound treatment, in particular for dry wound treatment.
  • the present invention relates to a dry wound treatment product characterized in that it contains unmodified lyocell fibers in its intended area to be applied to the wound.
  • the present invention therefore generally relates to the use of unmodified lyocell fibers for the manufacture of a wound treatment product.
  • Unmodified lyocell fibers have been found to significantly accelerate wound healing compared to other unmodified products heretofore used as a substrate in dry wound treatment (ie, products containing no drugs or wound healing promoting agents), particularly when compared to bleached cotton.
  • CMC fibers or fibers modified with chitosan represents a very large cost advantage.
  • the yarn used according to the invention, the textile fabric or the textile article are each substantially completely composed of non-modified Lyocell fibers.
  • the yarn used according to the invention, the textile fabric or the textile article may contain foreign fibers in an amount of up to 90%, preferably 10 to 50%.
  • unmodified lyocell fibers are understood to be various fibers, e.g. Cotton, polyester, viscose and modal fibers or modified lyocell fibers. Unmodified fibers are also preferably used as foreign fibers, ie fibers which are not modified or derivatized with active substances, etc.
  • a textile fabric for specific use according to the invention may be present in particular in the form of a woven, knitted, knitted or nonwoven fabric.
  • the invention relates to a product for wound treatment, in particular for dry wound treatment, which is characterized in that it contains non-modified Lyocell fibers in its area intended for laying on the wound.
  • the product according to the invention may in particular be selected from the group consisting of patches, wound dressings, bandages, bandages, gypsum underlay fabrics, underwear, pajamas for atopic dermatitis, orthopedic support bandages, support bandages, wound gauze, compresses, gauze, compression bandages, compression stockings and tubular bandages.
  • the wound treatment product according to the invention is preferably characterized in that the proportion of unmodified lyocell fibers in the area intended to rest on the wound is at least 10%, preferably 50% to 100%, particularly preferably 90% to 100%.
  • the remaining fibers in the area intended to rest on the wound can be foreign fibers as above, in particular non-modified foreign fibers.
  • the lyocell fiber used according to the invention can be present in a tanning range which is customary for textile products or nonwovens or in a customary cutting length.
  • the fiber may have a denier of 1.3 dtex and a cut length of 38 mm.
  • the fiber can be used in bleached form. Examples
  • Punctures with a diameter of 6 mm were taken from the plicae of washed and sterilized pig ears. From the center of the punches, the epidermis and the upper Dennis were removed in a range of 3 mm. Subsequently, the models were incubated in Air-Liquid Interphase at 37 ° C, 5% CO 2 and saturated humidity in the dermatological clinic. Immediately after generation of the models, 5 ⁇ l of PBS were applied to the control. For the other samples, 4 mm diameter platelets were removed from the knits using Biopsy punches and placed on the wounds.
  • the models were after 48 h snap frozen and at -8O 0 C.
  • the models were completely embedded in tissue freezing medium (Leica, Nussloch) and made with the cryostat 6 micron thin sections. It was ensured that you were in the middle of each model.
  • the sections were placed on Superfrost slides, air-dried 10 min cold acetone fixed and stored at -8O 0 C in -20 0 C.
  • HE staining (general morphology): All models were stained with hematoxylin / eosin (HE) (2 sections each). The staining was evaluated on a Leica light microscope DM LS and an Olympus Camedia digital camera. Evaluation parameters: Wound healing progress and morphology - Good / bad preservation of the wound margin (maceration)
  • the evaluation of the wound healing progress is based on the PBS control in order to take into account the wound healing potential of the respective pig, which is determined by the values obtained with PBS (physiological phosphate buffer).
  • PBS physiological phosphate buffer
  • the wound healing progress achieved only with PBS is thus the highest value (ideal wound healing) in the skin organ culture model that can be achieved (100% or value 1).
  • Sample 1 Polyester Fiber (Tergal PES)
  • Sample 2 Unmodified Lyocell Fiber
  • Sample 3 Bleached Cotton
  • Sample 4 PBS Control
