Description

Technical Field

[0001] This utility model relates to the technical field of textile fabrics for firefighters' firefighting suits, and in particular to a flame-retardant, heat-insulating, waterproof, and breathable fabric. Background Technology

[0002] Firefighter suits are specialized garments worn by firefighters during firefighting and rescue operations to protect the torso, head, neck, arms, and legs. In recent years, with the introduction of new materials and structures, the overall thermal protection performance (TPP value) of firefighter suits can be improved in various ways, and three-layer firefighter suits have gradually replaced the common four-layer firefighter suits.

[0003] Three-layer fire suits primarily improve overall thermal protection by increasing the weight of the waterproof, breathable, and insulating layers. Currently, the commonly used weight of the waterproof, breathable, and insulating layer in three-layer fire suits is 160g / m². 2 Through 120g / m 2 It is prepared by laminating aramid spunlace felt with polytetrafluoroethylene film.

[0004] Existing high-grammage waterproof, breathable, and heat-insulating layers suffer from a significant decrease in the hydrophobicity of the non-woven fabric substrate after several washes, resulting in strong water absorption. This leads to a substantial increase in the weight of the clothing after it absorbs moisture, which not only increases the overall load on firefighters but also makes it difficult for sweat to be quickly wicked away in humid and hot environments. This can cause firefighters to feel stuffy, experience a decrease in physical strength, and increase the risk of heat stress.

[0005] At the same time, the thicker the waterproof, breathable and heat-insulating layer, the better the heat insulation performance. However, the thicker the waterproof, breathable and heat-insulating layer, the heavier it is, and the worse the comfort performance, which affects the firefighters' combat effectiveness. Utility Model Content

[0006] This invention provides a flame-retardant, heat-insulating, waterproof, and breathable fabric for use as a waterproof, breathable, and heat-insulating layer in firefighting suits, in order to solve the technical problems of poor breathability, difficulty in quickly wicking away sweat, and heavy weight of existing waterproof, breathable, and heat-insulating layers.

[0007] The technical solution provided by this utility model is as follows:

[0008] One objective of this utility model is to provide a flame-retardant, heat-insulating, waterproof, and breathable fabric, which includes a polytetrafluoroethylene breathable membrane, a first flame-retardant fiber spunlace felt, and a second flame-retardant fiber spunlace felt.

[0009] The polytetrafluoroethylene breathable membrane and the first flame-retardant fiber spunlace felt are bonded together by a first dotted flame-retardant adhesive.

[0010] The first flame-retardant fiber spunlace felt and the second flame-retardant fiber spunlace felt are bonded together by a second dot-shaped flame-retardant adhesive;

[0011] The second flame-retardant fiber spunlace felt has an array of multiple small pores to increase the moisture permeability of the fabric.

[0012] In a preferred embodiment, the pores of the second flame-retardant fiber spunlace felt are circular or elliptical, and the pore diameter is 0.4-1.5 mm.

[0013] Multiple small holes are evenly distributed in a diamond shape, with a spacing of 4-7 mm between adjacent holes.

[0014] In a preferred embodiment, the second flame-retardant fiber spunlace felt is treated with a water-repellent and oil-repellent finish to reduce the water absorption of the fabric.

[0015] In a preferred embodiment, the second dotted flame retardant adhesive is used to bond the first flame retardant fiber spunlace felt and the second flame retardant fiber spunlace felt together by dot bonding.

[0016] The second dotted flame retardant adhesive has uniformly distributed diamond-shaped adhesive dots, with a spacing of 6-12 mm between adjacent adhesive dots.

[0017] In a preferred embodiment, the first flame-retardant fiber spunlace felt is treated with a moisture-wicking and quick-drying finish to enhance the moisture-wicking properties of the fabric.

[0018] In a preferred embodiment, the first dot-shaped flame-retardant adhesive is used to bond the polytetrafluoroethylene breathable membrane to the first flame-retardant fiber spunlace felt using a dot bonding method.

[0019] The adhesive dots of the first dotted flame retardant adhesive are uniformly distributed in a diamond shape, and the distance between adjacent adhesive dots is 2-3 mm.

[0020] In a preferred embodiment, the first dotted flame retardant adhesive and the second dotted flame retardant adhesive are selected from flame retardant polyurethane adhesives.

[0021] In a preferred embodiment, the fibers of the second flame-retardant fiber spunlace felt are selected from one or a mixture of multiple of para-aramid fibers, meta-aramid fibers, PBI fibers, polyimide fibers, flame-retardant polyester fibers, and flame-retardant viscose fibers.

[0022] In a preferred embodiment, the fibers of the first flame-retardant fiber spunlace felt are selected from one or a mixture of multiple types of para-aramid fibers, meta-aramid fibers, PBI fibers, and polyimide fibers.

[0023] The above-described technical solution of this utility model has at least the following beneficial effects compared with the prior art:

[0024] This invention provides a flame-retardant, heat-insulating, waterproof, and breathable fabric, comprising a polytetrafluoroethylene (PTFE) breathable membrane, a first flame-retardant fiber spunlace felt, and a second flame-retardant fiber spunlace felt. The PTFE breathable membrane and the first flame-retardant fiber spunlace felt are bonded together by a first dot-shaped flame-retardant adhesive. The first flame-retardant fiber spunlace felt and the second flame-retardant fiber spunlace felt are bonded together by a second dot-shaped flame-retardant adhesive. The second flame-retardant fiber spunlace felt has an array of multiple small pores, which increases the fabric's moisture permeability, breathability, and sweat-wicking properties, improves the fabric's comfort, and reduces the fabric's weight without affecting the overall thermal protection performance of the fabric.

[0025] This invention provides a flame-retardant, heat-insulating, waterproof, and breathable fabric. The second flame-retardant fiber spunlace felt undergoes a waterproof and oil-repellent treatment, reducing the fabric's water absorption.

The second dot-shaped flame-retardant adhesive is used to bond the first flame-retardant fiber spunlace felt and the second flame-retardant fiber spunlace felt together by dot bonding. This reduces the amount of the second dot-shaped flame-retardant adhesive used and reduces the impact of the second dot-shaped flame-retardant adhesive on the fabric's breathability.

[0028] This invention provides a flame-retardant, heat-insulating, waterproof, and breathable fabric.
