Viscose/Pulp Flushable Tissue Fabric: How to Optimize Curing Conditions to Ensure Best Reinforcement Effect?

Adhesive plays a vital role in viscose/pulp flushable tissue fabric. It not only determines the reinforcement effect of the paper web, but also directly affects the environmental performance and user experience of the product. Therefore, when selecting an adhesive, its type, performance and compatibility with the paper web fibers need to be considered comprehensively.

Types and Performance:
There are many types of adhesives, which can be divided into natural adhesives (such as starch, protein, etc.) and synthetic adhesives (such as polyvinyl alcohol, polyurethane, etc.) according to their sources.
Natural adhesives are environmentally friendly, but their strength and water resistance are relatively weak; synthetic adhesives are strong and water resistant, but may have a certain impact on the environment.
When choosing, it is necessary to weigh the pros and cons according to the product's usage scenario and environmental requirements and choose the most suitable adhesive.
Compatibility with fibers:
The compatibility of the adhesive with the paper web fibers is a key factor affecting the reinforcement effect.
The ideal adhesive should be able to form a strong chemical bond or physical entanglement with the fiber, thereby improving the overall strength of the paper web.
Therefore, when selecting an adhesive, sufficient testing and evaluation are required to ensure its compatibility with the paper web fibers.

After applying the adhesive, the paper web needs to go through a certain curing time so that the adhesive and the fiber are fully combined to form a stable structure. The setting of curing conditions is directly related to the efficiency and effect of this process.

Temperature:
Temperature is a key factor affecting the curing rate of the adhesive.
Generally speaking, as the temperature increases, the curing rate of the adhesive accelerates, but too high a temperature may cause the adhesive to cross-link excessively and reduce its flexibility.
Therefore, when setting the curing temperature, it is necessary to make precise calculations and adjustments based on the type and performance of the adhesive, as well as the material and thickness of the paper web.
Humidity:
Humidity also has an important influence on the curing process of the adhesive.
Excessive humidity may cause the adhesive to absorb too much moisture, prolong the curing time, and even affect the reinforcement effect.
Conversely, too low humidity may accelerate the drying of the adhesive, but it may also cause excessive water loss in the fiber, affecting the softness and strength of the product.
Therefore, when setting the curing humidity, it is necessary to comprehensively consider the ambient humidity, the moisture content of the paper web, and the curing characteristics of the adhesive.
Time and pressure:
In addition to temperature and humidity, curing time and pressure are also important factors affecting the reinforcement effect.
The length of curing time needs to be determined according to the type of adhesive, the thickness of the paper web and the required reinforcement strength.
The application of pressure helps the adhesive to better penetrate between the fibers and form a stronger bond.
When setting these parameters, sufficient experiments and optimization are required to ensure the best reinforcement effect.

The setting of curing conditions not only directly affects the bonding effect between the adhesive and the fiber, but also indirectly affects the overall performance of the viscose/pulp flushable toilet paper fabric.

Strength and durability:
Optimized curing conditions can ensure that the adhesive forms a strong bond with the fiber, thereby improving the strength and durability of the paper web.
This is of great significance for improving the service life of the product and reducing the breakage rate.
Softness and comfort:
The setting of curing conditions also needs to take into account the softness and comfort of the product.
Excessive temperature or pressure may cause excessive compression or cross-linking of the fibers, affecting the softness of the product.
Therefore, when setting curing conditions, it is necessary to balance the needs of strength and softness to ensure that the product is both strong and comfortable.
Environmental performance:
The optimization of curing conditions also needs to consider the environmental performance of the product.
Some adhesives may release harmful substances during the curing process, posing a potential threat to the environment and human health.
Therefore, when setting curing conditions, it is necessary to select adhesives with good environmental performance and strictly control the emissions during the curing process.
In order to optimize the curing conditions of viscose/pulp flushable toilet paper fabrics and ensure that they achieve the best reinforcement effect, producers need to continue to explore and innovate.

Testing and optimization:
Through a large number of tests and optimizations, find the most suitable combination of curing conditions.
