Embodiment 1
[0049] It is used for the preparation of step-by-step hot rolling modified non-woven fabrics, including the following steps:
[0050] ①Preparation of sizing modified solution (agent) for step-by-step hot-rolled modified non-woven fabrics:
[0051] In parts by weight, it includes the following components:
[0052]
[0053] After the above-mentioned components are measured separately, they are respectively added into the dissolution container with a stirring and heating device, and the stirring is started at a stirring rate of 80 rpm, and the heating is started, and the temperature is raised to a temperature range of 95°C. Keep it under high temperature for 2 hours to ensure that the polyvinyl alcohol is completely dissolved, lower the temperature to 90° C. and keep it warm for 1 hour for homogenization treatment, then cool to room temperature and discharge for later use to obtain a polyvinyl alcohol non-woven fabric sizing modification solution (agent).

Embodiment 2
[0063] It is used for the preparation of step-by-step hot rolling modified non-woven fabrics, including the following steps:
[0064] ①Preparation of sizing modified solution (agent) for step-by-step hot-rolled modified non-woven fabrics:
[0065] In parts by weight, it includes the following components:
[0066]
[0067] After the above-mentioned components are measured separately, add them into the dissolution container with a stirring and heating device, start stirring at a stirring rate of 250 rpm, and start heating to a temperature range of 100°C. Keep it under high temperature for 4 hours to ensure that the polyvinyl alcohol is completely dissolved, lower the temperature to 90° C. and keep it warm for 0.5 hour for homogenization treatment, then cool to room temperature and discharge for later use to obtain a polyvinyl alcohol non-woven fabric sizing modification solution (agent).
[0068] ②Use the gluing modification solution (agent) prepared in step ① to prepare polyv...
Embodiment 3
[0077] It is used for the preparation of step-by-step hot rolling modified non-woven fabrics, including the following steps:
[0078] ①Preparation of sizing modified solution (agent) for step-by-step hot-rolled modified non-woven fabrics:
[0079] In parts by weight, it includes the following components:
[0080]
[0081] After the above-mentioned components are measured separately, they are respectively added into a dissolution container with a stirring and heating device, and the stirring is started at a stirring rate of 150 rpm, and heating is started to raise the temperature to a temperature range of 98°C. Keep it under high temperature for 3 hours to ensure that the polyvinyl alcohol is completely dissolved, cool down to 90° C. and keep warm for 0.6 hours for homogenization treatment, then cool to room temperature and discharge for later use to obtain a polyvinyl alcohol non-woven fabric sizing modification solution (agent).
