Problems solved by technology

The reason is that most fruit bag paper manufacturers in my country are still at the level of simple imitation. On the one hand, although the products have achieved high strength, on the other hand, they have ignored the air permeability, water resistance and softness, etc. The balance of the index makes the fruit bag paper unable to adapt to the complex and changeable climate environment
At the same time, the problem of balancing the high strength index and high air permeability index of the outer bag paper has not been resolved

Abstract

The invention discloses a method for preparing high-air-permeability fruit cultivation bagging paper. The method comprises the following steps: pulping, grinding, pulp preparation, net forming and dewatering and drying. The fruit cultivation bagging paper prepared by the method has high air permeability, high carbon black utilization rate, high shading property and relatively high indexes such as tensile strength and bursting strength and can be used for preparing various fruit cultivation bagging paper, the problems of generally high strength and low air permeability which always exist in domestic fruit cultivation bagging paper are solved, the problems such as sun burn of fruits caused by low air permeability, fruit russeting and black spot disease are solved, and the air permeability, the strength and the water resistance index of the fruit cultivation bagging paper are balanced.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to a method for preparing high air permeability fruit-raising bagging paper. Background technique [0002] The air permeability of the fruit bagging paper is very important for the growth of the fruit. Only the good air permeability of the fruit bag paper can ensure the normal metabolism of the fruit, otherwise it will form a high temperature and high humidity environment, which will easily cause the fruit "sunburn" ", fruit rust and black spot disease appear. Taking Shaanxi as an example, the incidence rate in some orchards is as high as 50%, which has a lot to do with the air permeability of the paper bag. In addition, the air permeability of the fruit bagging paper is high, which can ensure that the apples are colored and mature earlier than those under the general bagging paper during the growth process, which can bring greater benefits to the fruit growers. [0003] Fru...
