RAISING SEEDING POLYESTER SPUNBOND NONWOVEN FABRIC AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: Provided is a raising seeding polyester spunbond nonwoven fabric which has a tissue structure so dense that the roots of the seeding do not pass through the seedbed formed with the nonwoven fabric while fluently passing water and nutrients therethrough, and easily separates the seeding from the nonwoven fabric. CONSTITUTION: A method of manufacturing the raising seeding polyester spunbond nonwoven fabric comprises the steps of: making filaments of 2-7 denier with low melting point polyester having an intrinsic viscosity of 0.50-0.68 and a melting point of 200-250 deg.C, and polyester having an intrinsic viscosity of 0.50-0.68 and a melting point of 260 deg.C; uniformly conjugating the low melting point polyester filaments with the usual polyester filaments to form a web; and fusing the web with an embossing roll having a bonding rate of 5-45%. The basic weight of the nonwoven fabric is 30-70g/m2, and the embossing pattern is shaped with a diamond, a square, a star, a circle, a rectangle, or an oval.
