Problems solved by technology

[0004] The commonly used flame retardants for fabrics are usually halogen flame retardants. Although these flame retardants have better effects, when a fire occurs, the halogen-containing flame retardant materials will produce a large amount of smoke and toxic corrosive hydrogen halide gas. , causing a secondary hazard

Embodiment 1

[0053] Embodiment 1 and the preparation of human contact layer

[0054] Take each raw material by the data of embodiment 1 in table 1, mix uniformly, loosen and pre-treat, card into raw sliver on carding machine; Combine mature sliver on drawing frame again; Carry out drafting and adding on roving frame Twisting, further drafting and twisting on the spinning frame to make blended yarn, the yarn linear density is 30tex. Then the blended yarn is woven into a plain weave structure with a large circular machine weft knitting method, with a grammage of 180g / m 2 , which is the human-contact layer of Example 1.

[0055] Table 1 Raw material composition list of the contact layer with people (unit: kg)

[0056]

[0057] The flame-retardant polyester in Table 1 was purchased from Shanghai Defulun Chemical Fiber Co., Ltd.; the flame-retardant nylon was purchased from EMS Swiss Chemical (China) Co., Ltd.; the aramid 1414 was purchased from DuPont, USA.

Embodiment 2

[0058] Embodiment 2 and the preparation of human contact layer

Abstract

The invention discloses a flame retardant cushion of a public bus seat. The cushion comprises a human-contacted layer, a heat insulating layer, a counter-fire layer and an aluminum foil layer in sequence, wherein the human-contacted layer is woven by the following components, after being mixed, in parts by weight by a conventional method:10-30 parts of wear-resisting and flame-retarding fibers, and 70-90 parts of flame-retarding and fire-preventing fibers; the heat insulating layer is woven by the following components, after being mixed, in parts by weight by a conventional method: 0-30 parts of hollow three-dimensional crimp polyester staple fibers, and 70-100 parts of one of the following fibers: poly-aromatic oxadiazoles fibers and modacrylic chloride; and the counter-fire layer is woven by one or more fibers of flame retardant polyester, flame retardant nylons, flame retardant adhesive, modacrylic chloride, poly-aromatic oxadiazoles fibers, polysulfonamide, aramid fibers 1313, aramid fibers 1414 and pre-oxidized fibers. The flame retardant cushion is excellent in flame retardance, comfort and wear resistance.

Description

technical field [0001] The invention relates to a flame-retardant back cushion for a bus seat. Background technique [0002] Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. Human beings can use and control fire, which is an important symbol of civilization progress. Fires in factories, warehouses, residential buildings, office buildings, shopping malls, waiting halls and many other buildings will bring huge threats and injuries to people's lives and bring losses to public and private properties. [0003] The bus is a fire occurrence point that is easily overlooked. When a fire breaks out in a bus, it is not easy to escape, rescue is difficult, and the passage is often blocked due to crowding, resulting in a tragedy of trampling on each other. Therefore, preventing fires in buses before they happen is the most effective way to reduce losses caused by fires and to ensure the safety of...
