Description

Technical Field

[0001] This utility model relates to a waterproof and antibacterial spunlace composite nonwoven fabric, belonging to the technical field of composite nonwoven fabrics. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is a type of fabric formed without spinning or weaving. It is made by orienting or randomly arranging short or long textile fibers to form a web structure, which is then reinforced using mechanical, thermal, or chemical methods. Nonwoven fabrics break through the traditional textile principles and have advantages such as short process flow, fast production speed, high output, low cost, wide application, and diverse raw material sources. Spunlace nonwoven fabric, due to its lightweight and soft properties, can be used as a medical nonwoven fabric, such as for wound dressing. However, wound dressing requires nonwoven fabrics with good waterproof and antibacterial properties to protect the wound. Therefore, how to prepare a waterproof and antibacterial spunlace composite nonwoven fabric has become a problem to be solved. Utility Model Content

[0006] The antibacterial spunlace nonwoven fabric includes a parallel web fiber layer and a cross-web fiber layer; and the cross-web fiber layer is located on the side close to the first nonwoven fabric layer.

[0007] The parallel web fiber layer uses alginate fiber; the cross-web fiber layer uses silver-based antibacterial nylon fiber.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the first nonwoven fabric layer and the second nonwoven fabric layer are composited by a waterproof adhesive arranged in a dotted, linear or mesh pattern.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the alginate fiber is sodium alginate fiber, silver alginate fiber or copper alginate fiber.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1

[0018] Combination Figure 1 This embodiment provides a detailed description. The waterproof and antibacterial spunlace composite nonwoven fabric involved in this embodiment includes a first nonwoven layer 1 and a second nonwoven layer 2 compositely bonded together. The first nonwoven layer 1 is a waterproof nonwoven fabric; the second nonwoven layer 2 is an antibacterial spunlace nonwoven fabric. The antibacterial spunlace nonwoven fabric includes a parallel-laid fiber layer 21 and a cross-laid fiber layer 22; and the cross-laid fiber layer 22 is located on the side closest to the first nonwoven layer 1. The fibers used in the parallel-laid fiber layer 21 are alginate fibers; the fibers used in the cross-laid fiber layer 22 are silver-based antibacterial nylon fibers.

[0019] Furthermore, the first nonwoven fabric layer 1 and the second nonwoven fabric layer 2 are bonded together with a waterproof adhesive arranged in a dotted, linear, or mesh pattern, which does not affect the breathability of the nonwoven fabric. In this embodiment, a dotted bonding structure is used, that is, the waterproof adhesive is evenly distributed in dots on the surface of the first nonwoven fabric layer 1, and then the second nonwoven fabric layer 2 is stacked with the first nonwoven fabric layer 1 and rolled together.

[0020] Furthermore, the alginate fiber is sodium alginate fiber, silver alginate fiber, or copper alginate fiber. In this embodiment, sodium alginate fiber is selected. It is a functional fiber material with high moisture absorption properties, prepared by wet spinning from sodium alginate. It is widely used in the medical and hygiene field and can absorb exudate from the wound site, thereby keeping the wound dressing dry.

[0021] The cross-laid fiber layer 22 reduces the difference in strength between the longitudinal and transverse directions of the second nonwoven layer 2, thereby increasing its strength. The parallel-laid fiber layer 21, on the other hand, increases the production rate of the second nonwoven layer 2.

[0022] Furthermore, the waterproof nonwoven fabric includes a viscose spunlace nonwoven fabric 11 and a waterproof and breathable membrane 12 bonded to the viscose spunlace nonwoven fabric 11 on the side away from the second nonwoven layer 2. The waterproof and breathable membrane 12 prevents moisture from passing through the first nonwoven layer 1 and affecting the wound.

[0023] Furthermore, the waterproof and breathable membrane 12 is a TPU microporous membrane or a PU microporous membrane, and in this embodiment, a TPU microporous membrane is selected.

[0024] Example 2

[0025] Combination Figure 2 This embodiment will be described in detail below. The waterproof and antibacterial spunlace composite nonwoven fabric involved in this embodiment differs from that in Embodiment 1 in that a seaweed carbon fiber nonwoven fabric layer 3 is provided between the first nonwoven fabric layer 1 and the second nonwoven fabric layer 2. Seaweed carbon fiber is a fiber produced by crushing seaweed carbon into ultrafine particles, then mixing it with polyester or nylon solutions, spinning it, and processing it into fibers. The fibers prepared from seaweed carbon can have a far-infrared emissivity of over 90% at 35°C, making it a high-value far-infrared emissivity material. Far-infrared radiation can activate the molecular movement within cells, producing resonance and generating a warming sensation inside the body. This activity can give cells vitality, making them full of life.

[0026] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
