Technical Solution Of New Textile Laminated Products

Hot-melt adhesive

The application of lamination has played a more and more important role.

Compared with traditional methods, hot melt technology has many advantages in process configuration, which can reduce product cost and play a positive role in environmental protection.

As a result, almost all famous coating equipment manufacturers are producing textile laminating machines suitable for a variety of gluing methods.

The hot-melt adhesive exists in solid form, melts at 90~180 degrees, and then spreads to the two matching base in liquid form.

The type of binder required depends on the coating method, coating material and bonding standards.

The combination of materials with different properties and high performance textile composites has been applied to modern applications, including carpet lining and foam coated fabrics.

Many kinds of high performance hot-melt adhesives have been developed to meet the special application requirements in various fields.

In the production of carpet, floor coverings and artificial turf, latex dispersant has been regarded as the leading technology to protect fibers in interlining or cloth.

But in the development of new equipment, carpet manufacturers are increasingly keen on hot-melt adhesives, because hot-melt technology has more advantages than latex coating systems.

The hot-melt adhesive is made entirely of solid materials. It differs from the latex dispersant system in that the melting binder must not be wasted during the necessary processing.

Half of the latex dispersant was evaporated during subsequent drying.

However, the use of hot-melt adhesives can completely reduce the drying process required and significantly save energy costs.

The visual contrast data from Henkel showed that even if the energy consumed during melting the adhesive was calculated, the hot melt adhesive could also reduce the cost by nearly 70%.

Another advantage is that the Liotex binder has a shorter curing time.

The rapid cooling of the melts can bring many benefits, such as carpets.

Further processing without consuming much time.

In order to improve the appearance of products, second layers of materials can also be laminated at the same time of hot melt, which significantly simplifies the production process, which is also unable to provide latex dispersant technology.

Modern hot melt technology is also suitable for foam coated textiles because of its good environmental compatibility.

Whether it is automotive interior materials or women's bra production, polyurethane type reactive hot flux has become a popular technology, replacing the technology of flame laminating by producing the composite foam by flame top layer.

Compared with flame melt lamination technology, the main advantage of the hot-melt adhesive is that the coating process does not discharge CO2 at all.

Therefore, the application of this new technology has reduced the additional investment in high cost safety equipment such as activated carbon filters.

The cost of the two technologies is very close to taking account of the consumption of materials when foam flame is melted.

In addition to the advantages of the above mentioned environmental compatibility, hot-melt adhesives have higher market flexibility in the selection of laminates.

For example, in the production of high quality welding furnace, the use of aliphatic polyurethane foam is increasing continuously, and the foam will not become yellow as time goes on, even if it does not contact with ultraviolet light directly, it will not turn yellow.

But, like others

Also, the foam is not suitable for flame fusion.

Therefore, no matter what direct comparison, hot melt technology provides a strong and convincing basis for the wide application of textile laminates.
