Heat transfer labels coming off? Leaving the fabric far behind?
We are often asked by customers why the heat transfer labels from the old supplier will come off from the clothes or bags? It leads to a lot of after-sale problems, such as complaints and returns.
Heat transfer labels are mainly heat press transfer type and heat sublimation transfer type, which are suitable for fabrics, plastics (including plates, sheets and films), ceramics and metals. There are various ways of flat printing, gravure printing, letterpress printing, inkjet and ribbon printing, etc. The substrates mainly include heat transfer paper and heat transfer plastic film.
In practical application, some challenges will be encountered, such as not all materials are suitable for thermal transfer, loss of color in the transfer process, poor temperature control leading to poor transfer results, not durable enough, and certain requirements for hot stamping technology. In the production and processing process, there are certain requirements for technology and equipment as well as the skill level of workers.
So, why is the heat transfer label easy to fall off? Mainly consider the following reasons:
1. Incorrect adhesion of hot melt adhesive of the label
Some manufacturers in order to reduce the cost, add too much filler, making the hot melt adhesive feel hard, not enough adhesion; or the label itself uses low temperature hot melt adhesive, the customer did not ask the specific temperature settings after getting the label, using high temperature, or in the washing with a higher temperature of water, so that the hot melt adhesive has a certain degree of melting, and the clothing is detached.
2. Problems with the fabric
The fabric has been pre-treated with waterproof treatment, soft finishing, the fabric contains substances with the ability to release, such as silicone; or the fabric texture is deeper, and the hot melt adhesive layer of the label is thinner, and the fabric is bonded to the fabric.The fabric has been pre-treated with waterproof treatment, soft finishing, the fabric contains substances with the ability of release, such as silicone; or the fabric texture is deeper, and the hot melt adhesive layer of the label is thinner, the amount of adhesive bonded with the fabric.The fabric has been pre-treated with waterproof treatment, soft finishing, the fabric contains substances with the ability of release, such as silicone; or the texture of the fabric is deeper, and the hot melt adhesive layer of the label is thinner, the amount of adhesive is not enough to bond with the fabric.The fabric has been pre-treated with waterproof treatment, soft finishing, the fabric contains substances with the ability to release, such as silicone; or the fabric texture is deeper, and the hot melt adhesive layer of the label is thinner, the amount of adhesive is not enough to bond with the fabric, resulting in detachment.The fabric has been pre-treated with waterproof treatment, soft finishing, the fabric contains substances with the ability to release, such as silicone; or the fabric texture is deeper, and the hot melt adhesive layer of the label is thinner, the amount of adhesive is not enough to bond with the fabric, resulting in detachment.The fabric has been pre-treated with waterproof treatment, soft finishing, the fabric contains substances with the ability to release, such as silicone; or the fabric texture is deeper, and the hot melt adhesive layer of the label is thinner, and the amount of adhesive bonded to the fabric is not enough, resulting in detachment.
3. Problems with the process conditions of production
The temperature of the press machine is not enough or the pressure of the press machine is not enough.
4. If the hot melt adhesive layer and the base layer of the label fall off, it is a quality problem, and you should find the supplier to return the product.
