Embodiment 1

[0023] Embodiment 1 selects nylon industrial filament to carry out following test, selects the nylon fiber raw material that meets the requirements: measure the linear density range of nylon fiber with a balance and a skein length measuring machine to be 420D ± 2.5%, measure its fracture with an electronic monofilament strength machine The strength should be between 6.5-9.5CN / dtex, and the elongation at break should be 16-29.7%. The shrinkage in boiling water should be between 6.0-8.5% when measured by a pressure cooker and a steel ruler.

[0024] The selected nylon long fibers are warped by batch warping machines. The number of warping threads is 1050. The warp shaft hardness of the warping machine is 70°~75°. It is 150±10m / min.

[0025] The nylon fiber filament after warping is sizing with KSH400 sizing machine. The hardness of the sizing shaft of the sizing machine is 70°~75°, the sizing temperature is 130~140°C, and the sizing rate is 5~6%. The speed is 100m / min, and the ...

Embodiment 2

[0032] Embodiment 2 Select nylon industrial filaments to carry out the following tests, select nylon fiber raw materials that meet the requirements: measure the linear density range of nylon fibers with a balance and a skein length measuring machine to be 420D ± 2.5%, measure its fracture with an electronic monofilament strength machine The strength should be between 6.5-9.5CN / dtex, and the elongation at break should be 16-29.7%. The shrinkage in boiling water should be between 6.0-8.5% when measured by a pressure cooker and a steel ruler.

[0033] Use batch warping machine to warp the selected nylon long fibers. The number of warping threads is 1050. The warp shaft hardness of the warping machine is 75°~80°. It is 150±10m / min.

[0034]After warping, the nylon fiber filaments are oiled. The fabric oil is a commercially available synthetic aqueous lubricating oil. The oiling temperature is 130-140°C, the oiling rate is 4-5%, and the paddle car speed is 100m / min. , The crimp te...

Abstract

The no-coating air bag fabric is tabby warp fabric of nylon yarn material, and has warp density of 18.5-19.5 /cm and weft density of 19-20 /cm. It is woven through the following steps: warping nylon yarn in a warping machine, sizing, rebeaming and tabby warp gaiting, weaving in a jet loom, desizing, and high temperature settling to obtain the no-coating air bag fabric. The process has low cost and is suitable for batch production.

Description

technical field [0001] The invention belongs to a safety airbag fabric for automobiles, in particular to a high-density, high-strength non-coated nylon filament non-coated airbag fabric and a preparation process thereof. Background technique [0002] Airbag fabric is the raw material for manufacturing automobile airbags. Its production technology has gone through several stages of development. The first generation is a sewn-type coated airbag fabric. The surface of the fabric is coated with neoprene, which has achieved the gas barrier effect; the second It is replaced by a sewn airbag fabric coated with silicone; the above-mentioned two generations of fabric mainly control the air permeability of the fabric through the coating. The third generation is sewn-type non-coated airbag fabric, which has gas barrier properties due to the structure of the fabric itself, and the fourth generation is non-coated fully formed airbag fabric, which is directly processed into a bag on the l...
