Description

Technical Field

[0001] The utility model relates to a fabric, in particular to a waterproof, moisture-permeable and flame-retardant composite fabric. Background Art

[0002] Waterproof, breathable fabrics are fabrics that, when used, prevent water from penetrating under a certain pressure, while allowing perspiration and other body vapors to pass through the fabric, keeping people dry and comfortable. Waterproof, breathable fabrics achieve this by exploiting the principle that the diameter of a water molecule is larger than that of a water vapor molecule. Clothing made from fabrics with pores much smaller than water droplets but much larger than water vapor molecules is made from these pores.

[0003] Flame-retardant protective fabrics are functional fabrics that slow the spread of flames when in direct contact with flames or hot objects, creating an insulating barrier to protect human safety and health. With economic development, demand for flame-retardant textiles has continued to grow. Simultaneously, with the gradual establishment and improvement of textile flame-retardant performance standards and fire regulations, the development and application of flame-retardant products has significantly increased in both variety and quantity, with a focus on multifunctional features such as flame retardancy, waterproofing, breathability, antibacterial properties, and antistatic properties. However, typical flame-retardant fabrics are made from flame-retardant materials or by adding flame-retardant ingredients to ordinary fibers. While these fabrics offer some fire resistance, they lack breathability, are not lightweight, and offer poor comfort. Firefighters, working in high-temperature environments, are frequently exposed to flames and high temperatures. They require protective clothing or products that must not only withstand high temperatures, but also experience exponentially higher perspiration levels due to intense physical activity. Combined with the extremely high ambient temperatures, these products can create a feeling of extreme dampness and dampness, severely impacting firefighters' operational efficiency.

[0004] Therefore, how to make the layers of thin and light fabrics firmly connected and at the same time have fireproof, waterproof and moisture-permeable functions is a key point and difficulty that needs to be solved urgently. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a waterproof, moisture-permeable and flame-retardant composite fabric which has a firm connection and has fireproof, waterproof and moisture-permeable functions.

[0006] The utility model is realized through the following technical measures:

[0007] A waterproof, moisture-permeable and flame-retardant composite fabric, characterized in that: it comprises a waterproof layer, a flame-retardant layer, a surface layer, a breathable and moisture-absorbing composite layer and a skin-friendly layer stacked in sequence from the outside to the inside, the flame-retardant layer comprises a base film, a silicone oil layer, a flame-retardant polyurethane layer and a blister film layer stacked in sequence from the inside to the outside, the base film is adhered to the outer surface of the surface layer, and the blister film layer is distributed with a plurality of flame-retardant bubbles formed by blistering; the breathable and moisture-absorbing composite layer comprises a first moisture-absorbing layer, a breathable layer and a second moisture-absorbing layer stacked in sequence from the outside to the inside, the breathable layer is adhered between the first moisture-absorbing layer and the second moisture-absorbing layer, a plurality of breathable holes are opened on the breathable layer, and the breathable holes penetrate the breathable layer and extend to the first moisture-absorbing layer and the second moisture-absorbing layer; the first moisture-absorbing layer and the second moisture-absorbing layer are both woven together by warp and weft, and the first moisture-absorbing layer and the second moisture-absorbing layer are provided with sweat channels connected to at least some of the breathable holes.

[0008] As a preference of the present application, the fire-resistant bubbles on the blister film layer are distributed in a ring matrix.

[0009] As a preferred embodiment of the present application, the waterproof, moisture-permeable and flame-retardant composite fabric also includes a breathable channel that penetrates the waterproof layer, the flame-retardant layer and the surface layer from the inside to the outside in sequence, the outer end of the breathable channel extends to the outer surface of the waterproof layer, and the inner end of the breathable channel is connected to the perspiration channel on the first moisture-absorbing layer.

[0010] As a preferred embodiment of the present application, the ventilation channel is a wedge-shaped through hole that is larger on the outside and smaller on the inside.

[0011] As a preferred embodiment of the present application, the air vent is a wedge-shaped through hole that is larger on the outside and smaller on the inside.

[0012] As a preference of the present application, the skin-friendly layer is a skin-friendly cotton layer woven from cotton yarn.

[0013] As a preference of the present application, the first moisture absorbing layer and the second moisture absorbing layer are both woven by warp and weft, and the warp and weft are both hollow shaped wires, and the outer surface of the shaped wire is formed with several perspiration channels extending along the axial direction of the shaped wire.

[0014] As a preferred embodiment of the present application, the cross section of the shaped wire is a circular ring as the center and a plurality of extension arms extending from the center to the periphery with the circular ring as the center, and a perspiration channel is formed between two adjacent extension arms.

[0015] As a preferred embodiment of the present application, the extension arms of two adjacent layers are arranged in a staggered manner, extending in the axial direction of the shaped wire.

[0016] As a preference of the present application, the number of the extension arms is 3 to 6.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. It has high fireproof and waterproof performance and good breathability; water-repellent grade (grade): grade 4; wash fastness (grade): grade 4-5; color fastness to rubbing: grade 4-5; LOI>29; breaking strength (N / 5cm×20cm): longitudinal 914, transverse 490; formaldehyde content: meets the national mandatory textile standard GB18401-2010;

[0019] 2. The flame retardant layer adopts a composite structure with good flame retardant effect. It can not only effectively reduce the so-called "frosting" defect on its migration surface, but also seal the escape of combustible gas and reduce the thermal radiation of the flame, so that the heat transmitted from the flame to the combustion transition zone is further reduced, thereby reducing the fire intensity and improving the flame retardant performance of the fabric. The flame-retardant bubbles distributed on the blister film layer can play a flame retardant role and a buffering effect, improving the flame retardant performance while improving the elasticity of the fabric.

[0020] 3. A breathable and moisture-absorbing composite layer is set between the surface layer and the skin-friendly layer. The breathable and moisture-absorbing composite layer uses the first moisture-absorbing layer, the breathable layer, and the second moisture-absorbing layer to form a siphon phenomenon. Sweat is discharged from the sweat channel to the breathable channel and then volatilized, thereby achieving the purpose of breathable moisture absorption and sweat elimination, greatly improving the moisture absorption and breathability of the fabric;

[0021] 4. The product has the advantages of flame retardancy, melting resistance, no toxic gas release, breathable and moisture permeability, and long-lasting elasticity. It can be used in various professional clothing, sportswear, civilian clothing, accessories, home textiles and other industries. Therefore, its market prospects are promising.
