What is solvent-free pu leather?

Solvent-free PU leather is an environmentally friendly artificial leather that reduces or completely avoids the use of organic solvents in its manufacturing process. Traditional PU (polyurethane) leather manufacturing processes often use organic solvents as diluents or additives, which may have negative environmental and health effects. To reduce this impact, solvent-free PU leather uses different manufacturing techniques, such as water-based technology or other environmentally friendly technologies, to replace traditional organic solvents.

So how is solvent-free PU leather produced?
Let’s first look at how solvent-free PU leather is produced:
1. Base cloth preparation: First, you need to prepare a base cloth, which can be cotton or other synthetic materials. This substrate will be the basis of PU leather,
2. Coating primer: Apply a layer of primer on the base cloth. This substrate is usually a polyurethane (PU), which has good adhesion properties and wear resistance.
3. Coating the top layer: After the primer is dry, apply a layer of love. This layer is also made of polyurethane, which determines the appearance and feel of PU leather. Some parts of the surface may require special treatment, such as embossing, printing or imitation leather texture, to increase the texture and beauty of the leather.
4. Drying and curing: After finishing the summer coating, the PU leather is sent to the drying room or through other curing methods, so that the primer and the surface layer are fully cured and combined.
5. Finishing and cutting: After the PU leather is processed, the finishing process needs to be carried out, including cutting into the desired shape and size in order to make the final leather products, such as bags, shoes, etc. The key point in the whole process is the use of solvent-free polyurethane (PU) paint. These coatings do not release organic solvents or release very small amounts of solvents during the coating process, thus reducing environmental pollution and the impact on workers’ health.

Why is solvent-free pu leather becoming more popular now?
Do we all have a problem, when we go to the mall to buy a sofa or furniture, see a beautiful and fashionable white leather sofa or leather furniture, want to buy, but also worry about the white leather sofa is not dirt resistant, not scratch resistant, not easy to clean, so many times will give up because of this reason, now do not worry, we have no solvent PU leather, Can help you with this problem. Solvo-free PU leather with its environmental protection, high performance and multi-functional characteristics, but also has the characteristics of dirt resistance, scratch resistance and easy cleaning, so we can choose the solvo-free PU leather made of white sofa, no longer have to worry about the white sofa is not dirty, no longer worry about naughty children drawing on the sofa with a pen.
Solvent-free PU leather meets the dual needs of modern consumers and manufacturers for product quality and environmental responsibility, which makes it a more environmentally friendly and sustainable option and is therefore increasingly favored in the market.
