Abstract

The invention discloses a polypropylene nonwoven fabric for preventing and controlling underground pests in tobacco planting and a production line thereof. The cavity is provided with a primary filter net and a card slot, and the vibrating spring and the second motor are used to vibrate the filter net at the same time. Compared with the traditional filtering method, the filtering effect is better. The production line is equipped with a pressing plate at the bottom of the driving device, and the bottom of the pressing plate is provided with a heating block, and the bottom of the electric box is provided with a lifting rod. When rolling, the height of the pressing plate can be adjusted in time through the lifting rod according to the thickness of the required non-woven fabric, and at the same time, the heating block is used to heat-treat the surface of the non-woven fabric, so as to achieve the purpose of adjusting the thickness of the non-woven fabric, which is different from the traditional fixed pressing Compared with the rolling method, the rolling method is more flexible, has a wider application range, and is more practical.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production, in particular to a polypropylene non-woven fabric for preventing and controlling underground pests in tobacco planting and a production line thereof. Background technique [0002] Polypropylene non-woven fabric is a new type of fabric product that does not require spinning and weaving. It has many advantages such as extensive sources, simple process flow, low cost, good mechanical properties, and relatively stable physical and chemical properties. It is widely used in the clothing and textile industry. , medical protective equipment, industrial matrix materials and other fields. However, due to the fact that there are only regularly arranged methyl groups in its molecular structure and lack of more functional groups and polar groups, polypropylene non-woven fabrics have defects such as poor aging resistance, poor hydrophilicity and poor dyeing ability, among which The poor hy...
