Abstract

The invention provides a preparation process of low-energy-consumption and environment-friendly polypropylene spunbond non-woven fabric. The preparation process comprises the steps of material mixing,drafting treatment, hot rolling humidification treatment and drying winding treatment, wherein, in the drafting treatment, a spinneret is introduced into a drafting machine for drafting treatment, the pressure of an air bellow of a drafting fan of the drafting machine is 2800 to 3800 Pa, the monomer suction air volume is 1200 to 1600 m<3> / h, and the temperature of upper cold air is 19 to 21 DEG C; the speed of a hot rolling mesh belt is 587 m / min, and the hot rolling pressure is 85 daN / cm; spinning obtained through the preparation process is smooth in hand feeling, complete in extension and uniform and consistent in hardness; and the obtained non-woven fabric product has the softness of 3.00 to 3.43 g and the shrinkage rate of 0.19% to 0.21%, and is not prone to deformation.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, and relates to a preparation process of non-woven fabrics, in particular to a preparation process of low-energy consumption and environment-friendly polypropylene spun-bonded non-woven fabrics and a non-woven fabric product thereof. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. [0003] Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of oriented or random fibers and is a new generation of environmentally friendly materials. , non-toxic, non-irritating, rich in color, low in price, recyclable and so on. For example, polypropylene (pp material) pell...
