Embodiment 1

[0048] The artificial leather base fabric layer is made of non-woven fabric made of superfine fibers impregnated with elastic polymer resin. The specific production steps are as follows:

[0049]A copolymer polyester comprising a polyester unit of metal sulfonate at 5 mole % and polyethylene terephthalate as a main component was melted to prepare a molten solution of a sea component. Polyethylene terephthalate (PET) was melted to prepare a melt of the island component. Thereafter, a composite yarn was spun using a melt of 50% by weight of the sea component and a melt of 50% by weight of the island component to obtain a single yarn fineness with 3 denier and 16 island components of filament. The filaments were drawn at a draw ratio of 1:3.5 to prepare sea-island fibers in the form of filaments. Thereafter, sea-island fibers were subjected to crimping so that the number of crimps was 15 / inch, heat-set at 130° C., and cut into 51 mm to produce sea-island fibers in the form of s...

[0085] The artificial leather base cloth layer is made of a non-woven fabric made of superfine fibers impregnated with an elastic polymer resin. The specific production steps are as follows:

[0086] A copolymer polyester comprising a polyester unit of metal sulfonate at 5 mole % and polyethylene terephthalate as a main component was melted to prepare a molten solution of a sea component. Polyethylene terephthalate (PET) was melted to prepare a melt of the island component. Thereafter, a composite yarn was spun using a melt of 50% by weight of the sea component and a melt of 50% by weight of the island component to obtain a single yarn fineness with 5 denier and 72 island components of filament. The filaments were drawn at a draw ratio of 1:3.5 to prepare sea-island fibers in the form of filaments. Thereafter, sea-island fibers were subjected to crimping so that the number of crimps was 15 / inch, heat-set at 130° C., and cut into 51 mm to produce sea-island fibers in the form...

Abstract

The invention discloses artificial leather with flame retardant property. The artificial leather comprises: an artificial leather base cloth layer, wherein the artificial leather base cloth layer is prepared by dipping a non-woven fabric made of superfine fibers in a non-woven manner into an elastic polymer resin and then performing superfine treatment, the fineness of the artificial leather basecloth layer is 0.1-0.3 denier, and the air permeability of the artificial leather base cloth layer is 50-70 L / min / 10 cm<2>; a flame-retardant layer, wherein the flame-retardant layer comprises a continuous flame-retardant area and a plurality of air holes uniformly distributed in the flame-retardant layer, the flame-retardant area accounts for 60-90% of the total area of the flame-retardant layer,and the flame-retardant area is coated with a mixture of a flame retardant and an adhesive; and a reinforcing layer adhered to the outer side of the flame-retardant layer and used for enhancing the strength of the artificial leather so as to maintain the stability of the shape of the artificial leather. The invention further discloses a preparation method of the artificial leather with the flameretardant property, and a preparation device of the artificial leather with the flame retardant property. According to the invention, the horizontal combustion speed of the artificial leather is 100 mm / min or lower, and the air permeability of the artificial leather is 20-50 L / min / 100 cm<2>; the use amount of the flame retardant and the adhesive is reduced, and the production cost is reduced; andthe softness is excellent, and the form stability is ensured.

Description

technical field [0001] The invention belongs to the technical field of artificial leather manufacture, and in particular relates to an artificial leather with flame-retardant properties, a preparation method and a preparation device thereof. Background technique [0002] Artificial leather is produced by impregnating elastomeric polymers with non-woven fabrics formed by non-woven microfibers into a three-dimensional structure. Since it has a soft texture and appearance similar to natural leather, it is widely used in various fields such as shoes, clothing, gloves, bags, furniture, and automotive interiors. The above-mentioned artificial leather needs to have higher performance in terms of flexibility, surface texture characteristics, abrasion resistance, light resistance and elongation characteristics, etc., depending on the purpose used, and sometimes needs to satisfy the above-mentioned various characteristics at the same time. [0003] For example, when artificial leathe...
