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 of the layer in contact with human beings (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

[0059] Each raw material was weighed according to the data of Example 2 in Table 1, and the human contact layer of Example 2 was prepared according to the method described in Example 1.

Embodiment 3

[0060] Embodiment 3 and the preparation of human contact layer

[0061] Each raw material was weighed according to the data of Example 3 in Table 1, and the human contact layer of Example 3 was prepared according to the method described in Example 1.

Abstract

The invention discloses an inflaming retarding cushion for a bus chair. The inflaming retarding cushion successively comprises a layer in contact with people, a heat insulation layer, a counterfire layer and an aluminium foil layer, wherein the layer in contact with people is formed by blending the following components in parts by weight: 10-30 parts of abrasion-proof fire retardant fibers and 70-90 parts of inflaming retarding fireproof fibers, and weaving the blended components by a conventional method; the heat insulation layer is formed by blending the following components in parts by weight: 0-30 parts of hollow three-dimensional crimped polyester staple fibers, 70-100 parts of one of the following fibers of inflaming retarding vinylon and preoxidized fibers, and weaving the blended components by a conventional method; the counterfire layer is woven by one or multiple kinds of fibers of inflaming retarding polyester fibers, inflaming retarding nylon, inflaming retarding viscose, modacrylic fiber with chloride, aromatic oxadiazoles fibers, polysulfonamide, aramid fibers 1313, aramid fibers 1414 and preoxidized fibers. The inflaming retarding cushion has excellent flame retardance, comfort feeling 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...
