What we usually refer to as“PVC roller shutter fabric”It is not a pure plastic film, but a composite polymer material, which can be understood as a combination of "high-strength fabric as the skeleton and PVC as the skin".

Its specific composition and characteristics are as follows:

1. Composition: Combination of two materials

PVC roller shutter fabric is mainly composed of two core components:

Base fabric (skeleton): usually made of polyester fiber (polyester), and a few special requirements may also use glass fiber. It is like steel bars in concrete, providing tensile strength and dimensional stability for roller blinds, ensuring that the fabric does not loosen over time.

Coating/wrapping layer (skin): namely polyvinyl chloride (PVC). It is wrapped inside and outside the base fabric, giving the fabric waterproof, mildew resistant, weather resistant, printable, easy to clean and other characteristics.

2. Proportion and Process: Proportion and Production

Common ratio: PVC roller shutter fabrics on the market usually follow a certain formula ratio to meet performance requirements. For example:

30% polyester fiber+70% polyvinyl chloride (PVC)

24% polyester fiber+76% polyvinyl chloride (PVC)

40% fiberglass+60% polyvinyl chloride (PVC)

Production process: PVC paste is coated on the woven base fabric through processes such as coating, rolling, or bonding, and then cured at high temperature to form. This also explains why it is often referred to as "PVC coated fabric".

Why is it called 'cloth'?

Because it retains the weaving texture and soft texture of textiles, it can be cut, sewn, and wound like fabric. At the same time, the addition of PVC makes it stronger, more durable, waterproof, and flame-retardant than ordinary cloth.

In summary, the essence of PVC roller shutter fabric is a functional composite material that uses PVC (polyvinyl chloride) as the "outer layer" and wraps high-strength polyester fibers as the "skeleton". This structure makes it both waterproof and dirt resistant like plastic, and soft and resilient like fabric, making it an ideal material for modern roller blinds.
