Description

Production process of high-strength pressure-resistant interior decoration cloth for motor vehicle
Technical Field
The invention relates to the field of automotive interior trim cloth, in particular to a production process of high-strength pressure-resistant interior trim cloth of an automotive vehicle.
Background
The fabric for the automotive interior mainly comprises synthetic fibers, wherein the polyester fibers account for more than 90% of the market of the automotive textile decorative fabric due to excellent mechanical performance and crease resistance, mildew resistance, low price and the like, and are widely applied to automobile seats, carpets, roof interiors, safety airbags and the like, but the fabric has low hygroscopicity and poor comfort; the polypropylene fiber is superior to polyester fiber in strength and density, is low in price and easy to recycle, but only can be dyed by stock solution or spun-dyed yarn, and is poor in wear resistance and hygroscopicity.
Because the fabrics for the interior decoration of the motor vehicle mostly use synthetic fibers, once a fire disaster occurs, molten drops are easy to generate, a large amount of dense smoke is accompanied, and the passengers are easy to lack oxygen and suffocate in a short time, so that the fabrics used for the interior decoration of the motor vehicle have higher requirements on the flame retardant degree and have stricter mandatory requirements on the control of smoke generation after combustion. The flame retardant requirement of the fabric used by the original automotive interior cloth only refers to national mandatory standard GB8410-2006 to control horizontal combustion, and the standard is not enough to effectively prevent and delay the spread of fire. Meanwhile, the interior trim fabric of the passenger car according to GB8410-2006 has serious defects in the aspects of flame-retardant durability and environmental protection, and the limited oxygen index is only 22%. Meanwhile, the electrostatic phenomenon of the interior decoration cloth is a problem which cannot be ignored. Firstly, static electricity can make a rider feel uncomfortable (particularly when wearing chemical fiber clothes), a friction discharge phenomenon is generated when the rider leaves a seat, and secondary accidents are easily caused when the driver takes a charge of static electricity; secondly, static charges are accumulated on the surface of the fiber and easily adsorb dust, which causes great troubles to the cleaning and maintenance in the vehicle; in addition, gasoline vapor or smoke generated by smoking may exist in the vehicle, which is easy to cause fire under the action of static electricity, and the static electricity can reduce the sensitivity of electronic components in the vehicle.
The automotive interior cloth usually has long service life along with the whole automobile, so the requirements on the strength, pressure resistance and comfortable air permeability of the fabric are high due to long-term sitting and pressing; more importantly, the flame retardant property and the antistatic property of the interior fabric of the motor vehicle have extremely important practical significance for ensuring the safety of drivers and passengers and reducing fire accidents. Therefore, how to overcome the defects in the prior art is a problem which needs to be solved urgently in the field of the current automotive interior fabric.
