Description

Technical Field

[0001] The utility model relates to textile fabrics, in particular to a flame retardant fabric structure with multiple additional functions. Background Art

[0002] Flame-retardant fabrics can effectively resist the burning of fabrics caused by high temperatures, reduce the flammability of fabrics in flames, slow down the spread of flames, and the fabrics can quickly extinguish themselves after the flames are removed. In addition to playing an irreplaceable role in the fields of industrial textiles, building interior decoration, and vehicle interior decoration, flame-retardant fabrics also play a lot of roles in the field of protective clothing. According to the national standards for flame-retardant protective clothing, metallurgy, forestry, chemical industry, petroleum, fire protection and other departments should use flame-retardant protective clothing. For example, patent document CN220703926U discloses a flame-retardant fabric, which includes an outer layer of barrier flame-retardant fabric and an inner layer of close-fitting flame-retardant fabric. The outer layer of barrier flame-retardant fabric is interwoven with warp yarns and weft yarns, and the warp yarns and weft yarns are aramid polyester flame-retardant yarns. The aramid polyester flame-retardant yarns include polyester core yarns and aramid yarns spirally wound around the polyester core yarns. The inner layer of close-fitting flame-retardant fabric is interwoven with warp yarns and weft yarns, and the warp yarns and weft yarns are spandex flame-retardant yarns. The spandex flame retardant yarn includes spandex core yarn, moisture-absorbing, breathable and antibacterial yarn and flame retardant modified bamboo pulp viscose yarn. The moisture-absorbing, breathable and antibacterial yarn is spirally wound on the outside of the spandex core yarn, and the flame retardant modified bamboo pulp viscose yarn is spirally wound on the outside of the moisture-absorbing, breathable and antibacterial yarn. The flame retardant modified bamboo pulp viscose yarn and aramid yarn have good flame retardant properties. The spandex core yarn and polyester core yarn have good elasticity and comfort. The cotton yarn and bamboo charcoal yarn have good moisture-absorbing, breathable and antibacterial effects.

[0003] As people's demands for clothing functions continue to upgrade, the single flame retardant function of this flame retardant fabric can no longer fully meet the needs of users. For example, the heat insulation effect is poor, resulting in high temperature burns to the skin, and it does not have external waterproof, dustproof, anti-fouling and other functions, and needs to be washed frequently when worn. Therefore, it is necessary to optimize the structure of this fabric to overcome the above defects. Utility Model Content

[0004] The utility model aims to provide a flame retardant fabric structure with multiple additional functions to improve the comprehensive performance of the fabric.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0014] The ion release components include:

[0015] The ion release layer is formed by compounding natural tourmaline powder and KH560 silane coupling agent and is filled in the flame retardant fabric layer.

[0016] This composite additive not only has excellent adhesion effect, but is also environmentally friendly and harmless to the human body. It is made by two-impregnation and two-padding finishing process, combined with the flame-retardant fabric layer at 50°C, and dried. It has excellent negative ion emission effect. When the addition amount is 4%, the initial negative ion release is 1300 / cm 3 It feels comfortable, has good air permeability, and is washable and friction-resistant.

[0017] The three protection components include:

[0018] The triple-proof finishing layer uses a fluorine-free waterproof agent to perform triple-proof finishing on the outer surface of the flame-retardant fabric layer to form a protective film, so that the flame-retardant fabric layer has the functions of being waterproof, dustproof and anti-fouling, avoiding the problem of harmful substances to the human body generated by fluorine-containing finishing agents during long-term use.

[0021] The heat-insulating coating layer is made of a photoactive polyurethane / SiO2 mixed aerogel finishing liquid and is formed by finishing the inner surface of the flame-retardant fabric layer through a scraping coating process.

[0022] This hybrid aerogel material not only effectively solves the defect that traditional inorganic aerogel materials are difficult to form films, but also significantly improves the thermal insulation effect of aerogel. The hybrid aerogel finishing liquid is coated on the inner surface of the flame-retardant fabric layer and dried at 50°C for about 3 hours to obtain the aerogel material.

[0023] The waterproof and breathable components include:

[0024] The waterproof and breathable membrane is formed on the surface of the thermal insulation coating layer by hot-melt lamination, so that the fabric can achieve waterproof and breathable functions from the inner layer, and protect and supplement the thermal insulation coating layer.

[0026] In one embodiment of the present invention, the mixing mass ratio of polyurethane to SiO2 in the photoactive polyurethane / SiO2 mixed aerogel is 1:15 to 1:20.

[0027] The advantages of the utility model are:

[0028] The core layer component of the flame-retardant fabric is made of flame-retardant fabric, and its internal fiber is aromatic polyamide fiber. This fiber has excellent heat resistance and insulation, can effectively resist the spread of flames, and ensure the personal safety of users in high temperature or fire environments.
