Patent ID: 8122839

Claim:
A method for manufacturing a natural fiber stripe-quilted fabric having protruded wrinkle patterns on its surface, the method comprising: a quilted raw fabric (A) preparation step in which cotton fabric sheets ( 1 , 2 ) made of one selected from a twill woven fabric and a plain woven fabric by using a 30S˜60S cotton fiber is prepared as a front surface sheet and a back surface sheet, and a cotton plate ( 3 ) made by needle-punching a raw cotton in a size of 2˜5 mm thick and a weight of 190˜210 g/m 2 is prepared as an intermediate material, and the cotton plate ( 3 ) is disposed between the cotton fabric sheets ( 1 , 2 ); a stripe-quilted fabric manufacture step in which the cotton plate ( 3 ) is inputted into a quilting machine while inputting the cotton plate ( 3 ) into between the cotton fabric sheets ( 1 , 2 ) and the fabric is sewed with an interval of a sewing line ( 4 ) being 5˜10 mm; a contraction/smoothening step in which the stripe-quilted fabric is inputted into a washing container of a rotary type washing machine ( 10 ) filled with a washing liquid, and the washing container is repeatedly rotated forwards and backwards for 15˜30 minutes for thereby performing a contraction and smoothening process; a dehydration process step in which the contracted and smoothened stripe-quilted fabric is taken out and is inputted into a centrifugal separator ( 20 ) for thereby performing a dehydration process; and a dehydration step in which the dehydrated stripe-quilted fabric is inputted into a rotation container of a circulation type hot air heater ( 40 ), and the rotation container is rotated for thereby performing a drying process for 60˜90 minutes under a hot air environment of 70˜90° C., wherein the steps are sequentially performed for thereby manufacturing protruded wrinkle patterns ( 1 a , 2 a ) protruded and wrinkled in a sewing direction and the sewing line of the front surface sheet and the back surface sheet of the fabric.
