In the realm of tissue production, hand towel tissue machines play a crucial role in meeting the ever - growing demand for hygienic and convenient hand towels. As a trusted supplier of hand towel tissue machines, I am often asked about the raw materials used in these machines. Understanding the raw materials is essential for both manufacturers looking to produce high - quality hand towels and businesses interested in purchasing our hand towel tissue machines. In this blog post, I will delve into the various raw materials commonly used in hand towel tissue machines and their significance.
Pulp: The Foundation of Hand Towel Production
Pulp is the primary raw material for hand towel tissue production. It can be sourced from different types of fibers, each with its own characteristics and advantages.
Wood Pulp
Wood pulp is the most widely used raw material in the tissue industry. It can be classified into two main types: softwood pulp and hardwood pulp.
- Softwood Pulp: Softwood trees such as pine, spruce, and fir have long fibers. These long fibers provide strength and durability to the hand towels. Softwood pulp is often used to enhance the tensile strength of the tissue, making it less likely to tear when in use. For example, when a person dries their hands vigorously, a hand towel with a good proportion of softwood pulp can withstand the stress without falling apart.
- Hardwood Pulp: Hardwood trees like eucalyptus, maple, and birch have shorter fibers. Hardwood pulp is known for its ability to create a smooth and soft surface on the hand towels. It also contributes to the absorbency of the tissue. Hand towels made with a blend of hardwood and softwood pulp can offer a balance of strength, softness, and absorbency.
Recycled Pulp
In recent years, there has been a growing trend towards using recycled pulp in hand towel production. Recycled pulp is made from waste paper products such as newspapers, magazines, and office paper. Using recycled pulp is an environmentally friendly option as it reduces the demand for virgin wood fibers. It also helps in reducing waste in landfills. However, recycled pulp may require additional processing to remove ink, dirt, and other contaminants. Despite these challenges, modern hand towel tissue machines are designed to handle recycled pulp efficiently, producing high - quality hand towels.
Chemical Additives
In addition to pulp, various chemical additives are used in hand towel tissue production to enhance the performance and quality of the final product.
Wet - Strength Resins
Wet - strength resins are added to the pulp mixture to improve the strength of the hand towels when they are wet. This is particularly important as hand towels are often used to dry wet hands. Without wet - strength resins, the towels would quickly disintegrate when exposed to moisture. Wet - strength resins work by forming cross - links between the pulp fibers, creating a more stable structure even in the presence of water.
Softeners
Softeners are used to make the hand towels feel softer and more comfortable against the skin. These chemicals reduce the friction between the fibers, giving the tissue a smooth and silky texture. There are different types of softeners available, including cationic softeners and non - ionic softeners. Cationic softeners are more commonly used as they have a better affinity for the pulp fibers and can provide long - lasting softness.
Brighteners
Brighteners are added to the pulp to improve the whiteness and brightness of the hand towels. They work by absorbing ultraviolet light and re - emitting it as visible light, making the towels appear whiter. Brighteners can enhance the aesthetic appeal of the hand towels, making them more attractive to consumers.
Packaging Materials
Once the hand towels are produced by the hand towel tissue machine, they need to be packaged properly to protect them from damage and maintain their quality.
Plastic Films
Plastic films are commonly used for packaging hand towels. They provide a barrier against moisture, dust, and other contaminants. Polyethylene (PE) and polypropylene (PP) are two of the most widely used plastic films in the tissue packaging industry. PE films are known for their flexibility and low cost, while PP films offer better clarity and stiffness.
Paperboard
Paperboard is another popular packaging material for hand towels. It is used to make boxes and cartons that can hold multiple packs of hand towels. Paperboard is a sustainable option as it is made from wood pulp and can be recycled. It also provides good protection for the hand towels during transportation and storage.
The Role of Hand Towel Tissue Machines in Processing Raw Materials
Our hand towel tissue machines are designed to process these raw materials efficiently and effectively. The machines are equipped with advanced technology to ensure that the pulp is evenly mixed with the chemical additives and formed into high - quality hand towels.
The first step in the process is the pulping stage, where the raw pulp is mixed with water to form a slurry. Our machines have precise control over the pulp consistency, ensuring that the right amount of water is added to the pulp. This is crucial as the consistency of the pulp affects the quality of the final product.
Next, the pulp slurry is fed into the forming section of the machine, where it is transformed into a continuous sheet of tissue. Our machines use advanced forming techniques to ensure that the fibers are evenly distributed across the sheet, resulting in a uniform and strong hand towel.
After the forming stage, the tissue sheet goes through a drying process. Our hand towel tissue machines are equipped with high - efficiency dryers that can remove the moisture from the tissue quickly and evenly. This helps in maintaining the strength and softness of the hand towels.
Finally, the dried tissue is cut and folded into individual hand towels and then packaged. Our machines can perform these operations with high precision, ensuring that the hand towels are neatly cut and packaged for distribution.
