I. Introduction

Non-woven fabrics have excellent properties such as softness, breathability, moisture absorption, and waterproofing, and are widely used in various fields. However, in practical applications, in order to enhance the functionality of non-woven fabrics, it is often necessary to coat the surface with a layer of glue to achieve waterproof, dustproof, antibacterial and other functions. As a commonly used coating equipment, the laboratory scraper has the advantages of high glue coating accuracy and easy operation, and is suitable for coating non-woven fabrics.

2. Experimental design

Experimental material preparation: Select common non-woven fabric samples as experimental materials, and choose different types and brands of glue as coating materials.

Experimental device: A laboratory scraper is selected as the coating equipment, equipped with a glue coating system, a scraper system, a drying system, etc., to realize the glue coating treatment of non-woven fabrics.

Experimental steps:

1. Cut the non-woven fabric to the desired size and clean the surface to remove impurities.

2. According to the experimental requirements, set the glue coating speed, scraper pressure, glue thickness and other parameters of the scraper.

3. Place the non-woven fabric on the squeegee machine, start the squeegee machine to conduct the glue coating experiment, and record the parameters and results during the glue coating process.

4. According to the gluing effect and experimental data, the influence of gluing process parameters on the gluing effect is analyzed, and the performance and stability of the scraper are evaluated.

3. Experimental results and analysis
