Production process formula of special non-woven fabric for fruit bags

Abstract

The invention relates to the manufacturing technology of non-woven fabrics, in particular to a production process formula of a special non-woven fabric for fruit bags. The formula comprises polypropylene and multiple finishing agents serving as main raw materials; the finishing agents comprise polysiloxane serving as a water-repellent finishing agent, salicylate serving as a sanitary finishing agent, hydroxymethyl stearic amide serving as a soft finishing agent, talcpowder or hydroxymethyl cellulose serving as a hard finishing agent and substituted benzotriazole serving as an ultraviolet-resistant finishing agent; and based on the whole raw materials, the finishing agents comprise 0.5 to 3 mass percent of polysiloxane, 1 to 3.5 mass percent of salicylate, 1 to 3 mass percent of hydroxymethyl stearic amide, 1 to 5 mass percent of talcpowder or hydroxymethyl cellulose, 0.5 to 2 mass percent of substituted benzotriazole, 2 to 5 mass percent of VBN glue (vinyl acetate-butyl acrylate-hydroxymethyl acrylamide copolymer emulsion), 1 to 5 mass percent of DMEU resin (dimethylol ethylene urea aldehyde resin creasing finishing agent) and the balance of polypropylene. The produced non-woven fabric serving as a special material for the fruit bags improves the air permeability of the fruit bags and ensures the inherent quality of the fruits; the method has simple production process and low environmental pollution; and the fruit bags can be reused, so the raw material cost is saved.

Description

technical field [0001] The invention relates to the manufacturing technology of non-woven fabrics, in particular to a production process formula of special non-woven fabrics for fruit bags. Background technique [0002] Over the years, in order to increase the price of fruit, fruit farmers have continuously increased the types and quantities of pesticides used in the orchard, resulting in serious pesticide residues in the fruit and increasing the resistance of diseases and insect pests in the orchard. This is a vicious circle. In response to the above problems, fruit farmers began to use bagging cultivation technology, and as the technology continues to mature, it has been promoted and popularized in China. Different fruits have different requirements for fruit bags, and now the most used in the north is apple fruit bags, which are made of fir wood pulp into fruit bag paper with good air permeability, and then waterproof treatment is carried out on the surface of the fruit b...

Problems solved by technology

Facts have proved that this paper bag cultivation technology improves the external quality of the fruit while greatly reducing the internal quality of the fruit

Moreover, the waste of environmental resources is serious, causing a lot of pollution

[0003] The main disadvantage of the existing fruit bags is that the air permeability of the fruit bag paper is very poor, resulting in the growth of the fruit in a high-temperature and high-humidity microenvironment, which seriously affects the internal quality of the fruit.

Secondly, fruit bag paper is made of wood pulp paper, which cannot be reused, wastes wood, and does not conform to the concept of environmental protection

Again, the manufacturing process of paper bags is complicated and pollutes the environment seriously
