<p>The present invention relates to a low shrinkage polyamide fiber suitable for use as a yarn of a fabric for airbags, and an uncoated fabric for airbags produced using the same. The uncoated fabric for airbags is produced by a method comprising the steps of: (A) weaving a low shrinkage polyamide fiber having a dry heat shrinkage of 3-6% (190 DEG C for 15 minutes) into a grey fabric for airbags; (B) heat-shrinking the grey fabric by successively passing it through 3-10 aqueous baths, the temperature of each of which is 5-20 DEG C higher than that of the preceding aqueous bath; (C) additionally heat-shrinking the fabric from the aqueous baths by passing it through a steam heater; and (D) drying the fabric from the steam heater by passing it through a hot air drier. <??>The fabric produced using the low shrinkage polyamide fiber of the present invention has high tensile strength and tear strength, and excellent quality, and thus, is useful as a fabric for airbags. <IMAGE></p> |
