Embodiment 1

[0044] Embodiment 1: as figure 1 , figure 2 , image 3 As shown, the present invention provides a flame-retardant high-speed rail seat cover, including: a back pocket 1 and a base pocket 2 connected to the back pocket; the back pocket and the base pocket are both made of composite fabrics , the composite fabric is woven from composite fiber, polyester yarn, and flame-retardant polyester thread at a ratio of 1:2:3; the composite fabric adopts a composite twill weave, wherein the warp density is 248 pieces / 10cm, and the weft density is 234 pieces / 10cm. In the present invention, the flame-retardant high-speed rail seat cover adopts a composite twill weave with a smaller weave coefficient and a higher tightness. Figure 4 . The surface of the composite fabric is also sprayed with a flame-retardant coating, which is composed of melamine-modified ammonium polyphosphate, pentaerythritol, and melamine cyanurate, and its ratio is 8: (1.5-2): (1.5 -2); The flame-retardant coating...

Embodiment 2

[0047] Embodiment 2: the present invention also provides a kind of flame-retardant high-speed rail seat cover production process, comprises the following steps:

[0048] 1) Bake the polyester masterbatch at 120°C for 3 hours; transport the slices quantitatively to the crystallizer for pre-crystallization, and then dry the crystallized slices at 145°C for 2 hours;

[0049] Add 1.5% color masterbatch to the flame-retardant polyester chips and send them to the screw extruder for melting and mixing. The melting temperature is 265°C. The melt is extruded by the extruder and directly enters the spinning process. The box is heated, and the heating temperature is 260°C; then one side is subjected to spinning, cooling, oiling, drawing and shaping, entanglement, and winding processes to obtain flame-retardant polyester filaments; among them, the spinning speed is 3800m / min; cooling The wind speed in the process is 0.5m / s; the hot air temperature is 25°C. In the drawing operation, the f...

Embodiment 3

[0057] Embodiment 3: The present invention also provides a kind of flame-retardant high-speed rail seat cover production process, comprises the following steps:

[0058] 1) Bake the polyester masterbatch at 120°C for 3 hours; transport the slices quantitatively to the crystallizer for pre-crystallization, and then dry the crystallized slices at 145°C for 2 hours;

[0059] Add 1.5% color masterbatch to the flame-retardant polyester chips and send them to the screw extruder for melting and mixing. The melting temperature is 270°C. The melt is extruded by the extruder and directly enters the spinning process. The box is heated, and the heating temperature is 270°C; then one side is subjected to spinning, cooling, oiling, drawing and setting, entanglement, and winding processes to obtain flame-retardant polyester filaments; among them, the spinning speed is 4000m / min; cooling The wind speed in the process is 0.7m / s; the hot air temperature is 227°C. In the drafting operation, the...

Abstract

The invention provides a flame retardant high iron seat cover. The cover comprises a backrest pocket and a base pocket connected with the backrest pocket; the backrest pocket and the base pocket are made from a composite fabric, and the composite fabric is formed by weaving a composite fiber, a polyester yarn and flame retardant polyester threads according to a ratio of 1:2:3; the composite fibercomprises a flame retardant fiber main part and an outer surface layer disposed outside the flame retardant fiber main part; the flame retardant fiber main part comprises a pair of side-by-side arranged flame retardant polyester threads and a pair of sleeves, the middles of the pair of flame retardant polyester threads are adhered to tapered metal fixing pieces, and the left and right sides of themetal fixing pieces are provided with arc curved surfaces for fixing the flame retardant polyester threads; the upper and lower ends of the middle of a metal fixing piece are respectively provided with puncture portions; the pair of sleeves respectively directly face the puncture portions of the upper and lower ends, and the two sides of the sleeves are in contact with the flame retardant polyester threads; the sleeves are filled with a pressurized gas fire extinguishing agent; the outer surface layer and the sleeves are both made from a flame retardant thermoplastic resin. The cover solves the problem that an existing high iron seat cover has a poor flame retarding effect.

Description

technical field [0001] The invention relates to the field of high-speed rail seat covers, in particular to a flame-retardant high-speed rail seat cover and a production process thereof. Background technique [0002] With the improvement of people's living standards and the continuous development and progress of human transportation technology, people's demand and dependence on travel tools are increasing. Transportation plays an intuitive and important role in the development of the national economy. Textiles are widely used in vehicles, trains, high-speed rails, airplanes and ships.
