Description

Technical Field

[0001] This utility model relates to the field of medical textile technology, and in particular to a medical dressing fabric. Background Technology

[0002] Skin is in direct contact with the external environment and is easily damaged by external forces, forming wounds. During the wound healing process, it is susceptible to infection by pathogens such as bacteria and fungi. Covering the wound with medical dressings can replace the damaged skin and act as a temporary barrier to prevent or control wound infection.

[0003] Existing medical dressings are mainly made through nonwoven multilayer materials, nanofiber membrane materials, and novel gauze dressing designs. Nonwoven dressings developed using novel biomass fiber materials have problems such as poor mechanical strength and lack of biocompatibility of interlayer adhesives. Nanofiber membrane dressings are difficult to industrialize and require an additional two layers of dressing. Novel gauze dressings have multilayer structures that are only connected at the edges, and after cutting, there is no connection between the multilayers, resulting in structural instability, difficulty in practical use, and easy waste. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a medical dressing fabric to improve the mechanical strength and stability of medical dressings.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A medical dressing fabric includes warp yarns and weft yarns. The warp yarns consist of an outer layer warp yarn and an inner layer warp yarn. The weft yarns consist of multi-layer outer layer weft yarn, multi-layer inner layer weft yarn, multi-layer core yarn, and weft cutting zone weft yarn. The fabric has a unit area mass of 300-500 g / m². 2 The fabric is divided into a multi-layer filling area, a warp single-layer cutting area, and a weft single-layer cutting area. The multi-layer filling area and the warp single-layer cutting area are arranged alternately along the weft direction, and the multi-layer filling area and the weft single-layer cutting area are arranged alternately along the warp direction.

[0007] Optionally, the multi-layer filling area includes a surface layer, a core layer, and an inner layer. The surface layer is a 1 / 1 plain weave structure formed by the interlacing of surface warp yarns and surface weft yarns of the multi-layer area along the warp and weft directions. The inner layer is a 1 / 2 twill weave structure formed by the interlacing of inner warp yarns and inner weft yarns of the multi-layer area along the warp and weft directions. The core layer is formed by filling the space between the surface layer and the inner layer with core yarns of the multi-layer area along the weft direction.

[0008] Optionally, the width of the multi-layer filling area distributed along the warp direction of the fabric is 2-10cm, and the length distributed along the weft direction is 2-10cm.

[0009] Optionally, the warp single-layer cutting zone is a 1 / 1+2 / 1 variation warp flat weave.

[0010] Optionally, the warp-direction single-layer cutting area has a length of 1-3 cm along the weft direction and a width of 2-10 cm along the warp direction.

[0016] The beneficial effects of this utility model are as follows:

[0017] The resulting multi-dimensional integrated fabric structure can be cut to any size. The interactive configuration of the yarns in each layer endows the dressing fabric with good biocompatibility, antibacterial properties, liquid absorption and moisture retention, breathability, and good mechanical strength.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 This utility model provides a medical dressing fabric.

[0023] A medical dressing fabric includes warp yarns and weft yarns. The warp yarns include an outer warp yarn and an inner warp yarn. The weft yarns include multi-layer outer weft yarns, multi-layer inner weft yarns, multi-layer core yarns, and weft cutting zone weft yarns. The fabric has a unit area mass of 300-500 g / m². 2 It includes a multi-layer filling area 1, a warp single-layer cutting area 2, and a weft single-layer cutting area 3. The multi-layer filling area 1 and the warp single-layer cutting area 2 are arranged alternately along the weft direction, and the multi-layer filling area 1 and the weft single-layer cutting area 3 are arranged alternately along the warp direction. This fabric has good biocompatibility, antibacterial properties, liquid absorption, and good breathability and mechanical strength of innovative gauze dressings, and will not stick to the wound and cause secondary damage.

[0024] Reference Figure 2 “O” represents the surface warp floating point; “V” represents the surface warp lift when the inner weft is woven in; “X” represents the inner warp lift when the inner weft is woven in; “S” represents the warp floating point of the warp cutting area; “M” represents the warp floating point of the weft cutting area.

[0025] The multi-layer filling zone 1 includes a surface layer 6, a core layer 5, and an inner layer 4. The surface layer 6 is an isolation layer, which is a 1 / 1 plain weave structure formed by the interlacing of the surface warp yarns and the surface weft yarns of the multi-layer filling zone along the warp and weft directions. The inner layer 4 is a contact layer, which is a 1 / 2 twill weave structure formed by the interlacing of the inner warp yarns and the inner weft yarns of the multi-layer filling zone along the warp and weft directions. The core layer 5 is an absorbent layer, which is filled between the surface layer 6 and the inner layer 4 by the core yarns of the multi-layer filling zone along the weft direction.

[0026] The surface warp yarn, the multi-layer surface weft yarn, and the weft yarn in the weft-cut area are blended yarns of antibacterial polyester fiber with profiled cross-section and hydrophobic fiber. The linear density of the blended yarn of antibacterial polyester fiber with profiled cross-section and hydrophobic fiber is 11.81tex×2~16.87tex×2. The surface layer 6 uses a plain weave structure and adopts blended yarn of antibacterial polyester fiber with profiled cross-section and hydrophobic fiber. The plain weave fabric has a uniform surface structure. After multiple spinning processes such as mixing, carding, and spinning, the two types of fibers in the blended yarn are fully mixed and uniformly distributed. The presence of antibacterial polyester with profiled cross-section gives the fabric good breathability and moisture permeability. Through the plain weave structure of the fabric and the full mixing of the two types of fibers in the yarn, the fabric achieves an effective combination of multiple properties such as breathability, moisture permeability, waterproofness, and barrier properties.

[0027] The inner warp yarn and the multi-layer inner weft yarn are blended yarns of milk protein fiber and indigo fiber. The linear density of the milk protein fiber and indigo fiber blended yarn is 10.74tex×2~14.76tex×2. The inner layer 4 uses a twill structure and is made of blended yarn of milk protein fiber and indigo fiber. Milk protein fiber contains amino acids, has good skin affinity, and good breathability, moisture wicking and smooth hand feel. Indigo fiber contains indigo extract, has good antibacterial properties, and its elliptical fiber cross-section gives the fabric a good silky feel and a soft touch. Combined with the good smooth structure of the twill, it further gives the fabric a smooth hand feel and avoids the dressing from sticking to the wound. At the same time, the moisture wicking property of milk protein fiber helps to guide wound fluid to the core layer 5 and keep the wound dry.

[0028] The multi-layer core yarn is made of pure alginate fiber yarn with a linear density of 36.9–59.1 tex. The core layer 5 is made of pure alginate fiber yarn. When alginate fiber products come into contact with body fluids containing sodium ions, they can be converted into sodium alginate hydrogels, which absorb wound fluids while maintaining the wettability of the wound, providing a suitable environment for wound healing.

[0029] The width of the multi-layer filling zone 1 along the warp direction is 2-10cm, and the length along the weft direction is 2-10cm. The length of the warp single-layer cutting zone 2 along the weft direction is 1-3cm, and the width along the warp direction is 2-10cm. The warp single-layer cutting zone 2 is a 1 / 1+2 / 1 variation warp-over plain weave. The length of the weft single-layer cutting zone 3 along the weft direction is the full width, and the width along the warp direction is 1-3cm. The weft single-layer cutting zone 3 is a 2 / 2 weft-over plain weave.

[0030] Through the combination of different materials and structures in a multi-layered structure, the inner layer 4 achieves antibacterial, skin-friendly, dry, and smooth properties, preventing the dressing from adhering to the wound; the core layer 5 is antibacterial and absorbent, preventing wound fluid accumulation and infection. At the same time, the gel state formed after the core layer 5 absorbs fluid can also provide a moist environment for the wound and promote wound healing; the surface layer 6 has a dense structure, forming a waterproof and breathable structure, which helps to expel excess moisture from the wound and isolate external pollution; the multi-layered structure works synergistically to provide a good growth environment for the wound.

[0031] The width of the multi-layer filling area along the warp direction is 2-10cm, and the length along the weft direction is 2-10cm. The length of the warp-single-layer cutting area along the weft direction is 1-3cm, and the width along the warp direction is 2-10cm. The warp-single-layer cutting area is a 1 / 1+2 / 1 variation warp-flat weave. The length of the weft-single-layer cutting area along the weft direction is the full width, and the width along the warp direction is 1-3cm. The weft-single-layer cutting area is a 2 / 2 weft-flat weave.

[0032] Through the combination of different materials and structures in a multi-layered structure, the inner layer achieves antibacterial, skin-friendly, dry, and smooth properties, preventing the dressing from adhering to the wound; the core layer is antibacterial and absorbent, preventing wound fluid accumulation and infection, while the gel state formed after the core layer absorbs fluid can also provide a moist environment for the wound and promote wound healing; the surface layer has a dense structure, forming a waterproof and breathable structure, which helps to expel excess moisture from the wound and isolate external pollution; the multi-layered structure works synergistically to provide a good growth environment for the wound.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
