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° 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° 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.
