TPU HJ-6125 is a high-performance polyurethane hot melt adhesive product. It is mainly used for heat transfer printing elastic fabrics, clothing interlinings, leather, and composite materials. It is very soft and elastic, with minimal impact on the skin feel and texture of the, excellent water washing resistance, and high bonding strength.

 

TPU hot melt adhesive powder feature one: bonding strength The importance of bonding strength is self-evident. It is the cornerstone ensuring product quality and maintaining customer base. For the purpose of heat transfer printing, it mostly comes into contact with materials like 100% cotton, polyester or nylon fabrics. In this case, there are many types of adhesive powders to choose from, including PA, PES, and TPU hot melt adhesive pow, all of which have good adhesion to fabrics and can ensure long-term use without delamination. However, EVA adhesive powder is not suitable, as it very selective of textiles. According to tests, EVA adhesive powder is only suitable for polypropylene fabrics, and its bonding strength on other fabrics is generally poor Therefore, EVA is excluded.

 

Feature two of PU hot melt adhesive powder: water washing resistance One of the most critical properties of hot melt adhesive powder for heat transfer printing its resistance to water washing. This is because the materials that require heat transfer printing, such as T-shirts, are often clothing items that need frequent washing. If adhesive powder detaches after washing, it will affect the product's quality and lead to the loss of customers, which is not cost-effective for merchants. Therefore, melt adhesive powders like PA and EVA cannot be used, and only PES or TPU hot melt adhesive powders can be used

 

TPU hot melt adhesive powder feature three: elastic and soft Secondly, the hand feel of the transfer print is also one of the factors. Although the hand feel of the fabric will definitely be harder than before after heat transfer printing, being softer is definitely what customers want. Compared to PES powder, medium and high temperature TPU adhesive powder are softer and more elastic, and using these products for transfer printing will have a smaller impact on the hand feel the fabric.

 

Feature four of TPU hot melt adhesive powder: higher efficiency and no thermal damage to materials Improving product production efficiency has always an unrelenting pursuit of manufacturers, and this is also the case for heat transfer merchants. Low-temperature adhesive powder allows merchants to use lower operating temperatures when the powder applicator (powder spreader) to apply adhesive, which not only saves electricity to a certain extent but also increases production efficiency, greatly reducing the cost of products. Moreover, the efficiency of medium and low-temperature heat transfer stickers when heat pressed onto clothing will be higher. The second benefit of medium and-temperature operations is that it will not cause thermal damage to materials. This is not significant for fabrics, but it is crucial for leather. Leather is very susceptible heat damage when exposed to temperatures above 180°C, causing the leather surface to become shiny and less durable. Therefore, using medium and low-temperature powder is more suitable for the heat transfer industry.
