Embodiment 1

[0051] A preparation method of a cold protection cloth, comprising:

[0052] S10, in the first spunbond non-woven fiber preparation step, the specific steps are as follows: put the PP resin, anti-aging agent, color masterbatch, and PP compatibilizer into the first plastic mixer after fully mixing, The vacuum suction machine sucks the material into the first large screw extruder and melts it into a melt and extrudes it. After the melt is filtered out by the first filter, it is sent to the first spinneret box through the first gear metering pump. The melt is ejected from the nozzle of the first spinneret box under its own gravity to form filaments, and after being cooled by the first air-conditioning cold air, the melt is stretched into filaments to obtain the first spunbond non-woven fibers; wherein, the first large screw extrudes The temperature of the machine is 228℃, the temperature of the first spinneret box is 228℃, the pressure of the first spinneret box is 4.5MPa, the te...

[0062] A preparation method of a cold protection cloth, comprising:

[0063] S10, in the first spunbond non-woven fiber preparation step, the specific steps are as follows: put the PP resin, anti-aging agent, color masterbatch, and PP compatibilizer into the first plastic mixer after fully mixing, The vacuum suction machine sucks the material into the first large screw extruder and melts it into a melt and extrudes it. After the melt is filtered out by the first filter, it is sent to the first spinneret box through the first gear metering pump. The melt is ejected from the nozzle of the first spinneret box under its own gravity to form filaments, and after being cooled by the first air-conditioning cold air, the melt is stretched into filaments to obtain the first spunbond non-woven fibers; wherein, the first large screw extrudes The temperature of the machine is 225°C, the temperature of the first spinneret box is 225°C, the pressure of the first spinneret box is 4MPa, the te...

Abstract

The invention discloses a preparation method of cold-proof cloth and a product. The preparation method comprises the following steps: S10, preparing first spun-bonded non-woven fabric fibers; s20, a first melt-blown cloth fiber preparation step; s30, a second spun-bonded non-woven fabric fiber preparation step; s40, a second melt-blown cloth fiber preparation step; s50, a third spun-bonded non-woven fabric fiber preparation step; s60, laying to form a net: obtaining a five-layer composite net cloth; and S70, hot rolling forming, wherein the composite net cloth is conveyed to a hot rolling machine through a net curtain to be subjected to hot rolling forming, and the five-layer cold-proof cloth is obtained. The invention has the characteristics of stability, difficulty in separation and good waterproofness, also has the characteristics of cold protection, heat preservation, air permeability and coloring promotion, and is suitable for heat preservation and freeze prevention of various fruit trees and medicinal materials such as citrus, sugar orange and dragon fruit.

Description

technical field [0001] The invention belongs to the technical field of cold-proof cloth, and in particular relates to a preparation method and product of a cold-proof cloth. Background technique [0002] Non-woven fabric is a kind of fabric formed without spinning and weaving, but by orienting or randomly arranging textile staple fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. With the development of agricultural technology, people gradually realize the important role of agricultural cold-proof cloth in the protection of crops and fruit trees. At present, some areas use paper or PE as raw material to produce cold-proof cloth. Once the paper cold-proof cloth encounters water It will become wet, and it will be damaged when wetted by rain in relatively bad rainstorm weather, and it will not play the role required for cold protection. The cold-proof cloth made of PE is difficult to degrade, causing serious env...
