Introduction of Yuzhimu nonwoven primary carpet backing

Carpets usually have two layers of backing, primary and secondary. Primary backing is the first layer of the carpet, directly attached to the pile yarn of the carpet, providing support and fixation. Non woven primary carpet backing is the first basic support layer in carpet structure, directly attached to the pile yarn of the carpet, mainly used to fix the pile and provide preliminary structural stability for the carpet. Here is a detailed introduction about it：

Function：

Fixed pile: By tightly fixing the pile yarn on the backing to prevent the yarn from falling off or loosening, the durability of the carpet is ensured.

Provide basic structure: Provide initial shape and strength for the carpet to keep it flat and not easily deformed during laying.

Enhance dimensional stability: reduce the shrinkage or expansion of carpets during temperature and humidity changes, and extend their service life.

Yuzhimu nonwoven primary care backing manufacturing process：

Made by thermal bonding (PET+PP), it has stronger stability.

Advantages: Fast production speed, suitable for large-scale economical carpets.

Key performance：

Tensile strength: affects the deformation resistance of carpets during laying and use.

Dimensional stability: prevents shrinkage or expansion caused by moisture or temperature changes.

Adhesive performance: Compatibility with latex ensures a strong bond with secondary backing.

Environmental friendliness: Recyclable material (PET).

Difference from Secondary backing：

Primary backing is the first layer of the carpet, mainly responsible for fixing the pile and providing basic support; The secondary backing is the second layer, usually attached to the primary backing by adhesive or hot pressing, further enhancing the strength, tear resistance, and slip resistance of the carpet.

In conclusion：
Yuzhimu nonwoven primary carpet backing is the "skeleton" of carpets, and material selection and craftsmanship directly affect the durability, appearance, and environmental friendliness of carpets. With technological advancements, optimizing the performance and improving sustainability of synthetic materials have become a focus of the industry. When choosing a carpet, it is necessary to consider the usage scenario.
