New Materials: Environmental Attention Of Textile And Clothing In The Future In The Application Of Hot Melt Adhesive

In the context of the overall slowdown of world economic development, hot melt adhesive has become a bright spot in the global adhesive market. The rapid development of the adhesive industry has provided many new adhesives with excellent performance for the society, but also brought new problems to the environment. At present, the function and application of adhesives have received extensive attention, while the environmental protection of adhesives is often overlooked.

Whether environmental protection has become the bottleneck of further development of adhesives, and solving the problem of environmental pollution has become an urgent task. Driven by environmental protection, health and safety factors, the market demand for environmentally friendly hot-melt adhesives is increasing.

The environmental friendly hot melt adhesive generally uses the following components:

Polyvinyl chloride (PVC): PVC is a widely used material, which can be used as raw material for manufacturing hot melt adhesive. When it melts, it will produce volatile organic compounds (VOC) and other harmful substances.

Nitrile rubber (nitrile urea formaldehyde rubber): nitrile rubber can be resistant to oil, corrosion and high temperature, and its composition can be selected according to different needs.

Amino resin (NHS): Amino resin is a kind of resin that can fix colors. It can form a firm fit between the fabric and hot melt adhesive, and has a certain water resistance.

Polymer electrolyte (PLC): PLC is an electrolyte that can promote the curing of glue.

Pigment (optional): Pigment can be used to fix color and enhance the color of fabric.

The proportion and combination of these ingredients can be selected and adjusted according to the specific needs and the requirements of the manufacturer.

Does the thermosol affect the human body?

Thermosol (thermoplastic adhesive) is a kind of colloidal material that is easy to dissolve and flow when heated. It is usually used to make shoes, furniture, car interiors, fabrics and other items.

Although thermosols themselves are not directly harmful to human body, they may have some side effects during use and treatment.

Here are some possible impacts:

Bad smell: The thermosol may produce some bad smell at high temperature, such as ammonia, hydrogen sulfide, etc. If the thermosol is heated at high temperature for too long or improperly treated, it may have a negative impact on health.

Bacterial infection: The thermosol may become unstable during heating, leading to the growth of bacteria, fungi and other microorganisms. Therefore, special care should be taken when handling the thermosol, and proper handling and storage methods should be followed.

Residues: if the thermosol is not properly separated and treated after heating, some residues may be formed, which may have a negative impact on health.

Therefore, attention should be paid to the use and handling methods of hot-melt adhesive when using it, and correct operating procedures should be followed to minimize potential health risks.

The use of hot-melt adhesive for fabric fitting may have a certain impact on the skin, depending on the type of hot-melt adhesive used, fitting conditions, personal skin texture and other factors.

Thermosol is a substance that dissolves raw materials by heating them. Its composition and properties vary according to its use. If the hot-melt adhesive used contains some chemical substances, such as sensitizers or irritants, it may cause irritation or allergic reaction to human skin.

In addition, the temperature and pressure during fitting may also affect the health of the skin. If the temperature and time are too high, it may lead to the decomposition of the thermosol or produce harmful gases. At the same time, too high pressure may lead to the release of chemicals in the thermosol into the air, causing discomfort.

Therefore, these factors should be taken into account when selecting and using hot-melt adhesives, and the type and composition that meet your needs should be selected. When using hot-melt adhesive to fit the fabric, it is recommended to follow professional guidance and safety specifications to minimize the impact on the skin.

There are many alternatives for fabric fitting without hot-melt adhesive, depending on the purpose you want to achieve. Here are some possible alternatives:

Heat shrinkable sheet: Heat shrinkable sheet is a reusable binding material, which can bind the fabric and heat shrinkable sheet together, and then shrink the heat shrinkable sheet with heat shrinkable agent and stick it tightly to the fabric. This material can be reused to save energy, and is suitable for scenes that need to be stored for a long time or need to be fitted for many times.

Glue fitting: Glue fitting is a traditional fitting method. Glue is used to combine the fabric with the fabric to be fitted. This fitting method is applicable to scenes requiring multiple fitting, such as textile packaging or clothing manufacturers.

Electronic fitting: electronic fitting is a fitting technology using electronic components, which can realize automatic fitting and is suitable for scenes requiring high precision and efficiency, such as electronic product manufacturing.

Chemical fitting: chemical fitting uses chemicals to fit the fabric and the fabric to be fitted together. This fitting method is applicable to scenes where special treatment or high frequency of treatment is required for the surface material, such as the fitting of silk and wool fabrics.

Different fabric fitting methods have different alternatives, and the selection of the most suitable method depends on the specific application scenario.
