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, comprising: a back pocket 1 and a base pocket 2 connected to the back pocket; both the back pocket and the base pocket are made of composite fabrics, The composite fabric is woven from composite fibers, polyester yarns, and flame-retardant polyester threads at a ratio of 1:2:3; the composite fabric adopts a composite twill weave, wherein the warp density is 248 threads / 10cm, and the weft density is 234 threads / 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, and the flame-retardant coating is configured by melamine-modified ammonium polyphosphate, pentaerythritol, and melamine cyanurate, and its proportioning ratio is 8: ...

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 a 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 fir...

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 a 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 f...

Abstract

The invention provides a flame-retardant high-speed rail seat cover, comprising: a back pocket and a base pocket connected to the back pocket; both the back pocket and the base pocket are made of composite fabrics, the composite fabric is made of composite fibers Polyester yarn and flame-retardant polyester thread are woven at a ratio of 1:2:3; the composite fiber includes a flame-retardant fiber main part and an outer layer arranged outside the flame-retardant fiber main part; the flame-retardant fiber main part includes a pair of side-by-side Flame-retardant polyester thread and a pair of sleeves, a tapered metal fixing sheet is attached to the middle of a pair of flame-retardant polyester threads, and the left and right sides of the metal fixing sheet have curved surfaces for fixing the flame-retardant polyester thread; the middle part of the metal fixing sheet The upper and lower ends are equipped with piercing parts; a pair of sleeves are respectively facing the upper and lower ends of the puncture parts, and the two sides of the sleeves touch the flame-retardant polyester thread; the sleeves are equipped with pressurized gas fire extinguishing agent; the outer layer and the sleeve are both Made of flame retardant thermoplastic resin. The invention solves the defect that the flame retardant effect of the existing high-speed rail seat cover is poor.

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 a vital role in the development of the national economy, and textiles are widely used in vehicles, trains, high-speed rails, airplanes and ships. According to statistics, the total mileage of my country's high-speed railways has exceeded 130,000 kilometers, and China has become the country with the most complete high-speed railway system technology, the strongest integration capabilities, the longest operating mileage, the highest operating speed, and the largest scale in the world. High-speed rail has become an important means of transportation for na...
