PVC tarpaulin is a polyester-filament fabric coated with PVC on both sides. It is widely used as a protective material in everyday and industrial applications, combining waterproof performance with aging, antistatic and tear-resistance properties.

PVC TARPAULIN COATING AND FINISHING:

The vertical-machine process described below applies a PVC formulation to the base fabric, controls the coating with a knife scraper, then dries and finishes the coated material.

  1. Feed and straighten the fabric. The base fabric is drawn straight through the machine and into the PVC formulation tank.
  2. Apply the PVC coating. A high-purity PVC formulation adheres to the textile. Both sides are kept straight as the knife-scraping stage controls the coating layer.
  3. Dry the coated fabric. The material passes through a drying oven. The process described here uses either electric heating or a boiler-heated drying system.
  4. Trim and wind. After drying, the edges are trimmed and the material is slit and wound into rolls.
  5. Pack the finished material. The finished rolls are packaged for handling and supply.

Vertical-machine production places high demands on raw-material purity. PVC canvas produced by this process is often somewhat more expensive and has a high-purity coating formulation.

Appearance and coating surface

A well-produced surface has good color and luster with a glossy, reflective appearance. One side is flat and smooth, while the other may have a slightly granular texture. Appropriate resin content and processing temperature help produce a pinhole-free surface with high resin density, good aging resistance and long service life.

Tensile strength

The production process and material formulation help preserve the strength of the base fabric. A higher warp and weft yarn density contributes to greater tensile strength.

Waterproof performance

PVC tarpaulin provides 100% waterproof performance with a good, continuous coating and no pinholes. Raw-material quality, resin content and coating density influence the finished material’s performance.

Handle and thickness

The material has a soft handle without a rough feel. Although it can feel less bulky than expected, its thickness meets the intended requirements; the resin content and processing quality contribute to this soft finish.

Material and environmental performance

The construction uses polyester-filament base fabric with double-side PVC coating and selected high-quality, environmentally friendly resin. It has a smooth surface, bright colors and waterproof, fire-resistant, corrosion-resistant, mildew-resistant, cold-resistant, high-temperature-resistant, UV-resistant and anti-aging properties.

FAQ

What is the purpose of knife scraping in PVC tarpaulin production?

The knife-scraping stage controls the PVC coating layer on the textile as the fabric travels through the machine. Coating formulation and processing temperature also influence the finished surface, density and handle.

How is the coated tarpaulin dried and finished?

The fabric passes through a drying oven with electric heating or a boiler-heated system. It is then edge-trimmed, slit, wound into rolls and packaged.

What should I specify when selecting PVC coated tarpaulin?

Include the finished application, required weight, width, color, surface finish, quantity and fabrication method. Describe the waterproofing and other performance requirements for your product. Review the PVC tarpaulin material range or send your tarpaulin requirements.

Choosing between canvas and PVC tarpaulin starts with the job: a fitted vehicle cover, a tent, a truck cover or a canopy places different demands on the fabric. Canvas uses cotton or a polyester-cotton blend, while PVC tarpaulin uses a polyester base fabric with a coated or laminated PVC surface. Compare water resistance, breathability, UV exposure, fire-performance requirements and cost before selecting a grade.

CANVAS VS PVC TARPAULIN AT A GLANCE:

Selection factor Canvas PVC tarpaulin
Material Cotton or polyester-cotton blend Polyester fabric coated or laminated with PVC
Typical applications Fitted vehicle covers, tents, folding-chair furniture and parasols Tarpaulins, lorry covers, furniture, machine covers and canopies
Water exposure Water-resistant canvas resists rain penetration; water resistance is different from waterproofing Coated or laminated surface suited to water-shedding covers; specify the finished cover and seams
Breathability The more breathable choice in this comparison, including lightweight PU-coated canvas Continuous PVC surface prioritizes a protective cover rather than airflow through the fabric
Shrinkage Cotton canvas shrinks; polycotton is less likely to shrink Synthetic fibres avoid the cotton-related shrinkage of canvas
Outdoor exposure UV stabilization influences service life and price UV stabilization influences service life and price
Fire performance Select a specified flame-retardant grade when required Select a specified flame-retardant grade when required
Cost comparison Generally more expensive because of the cotton fabric Generally the lower-cost option in this material comparison

WHAT IS CANVAS FABRIC?

Canvas can be made from cotton or a polyester-cotton blend, also called polycotton. Polycotton combines synthetic and natural fibres, generally costs less than cotton canvas and is less likely to shrink.

Common canvas applications include fitted vehicle covers, tents, furniture such as metal folding chairs, and parasols. The fabric construction and finish should match the finished item’s shape and exposure.

PU-coated canvas has a polyurethane layer over the fabric and is available in plain or ripstop weave. Its lightweight construction makes it the more breathable option in this comparison and allows it to adjust to body temperature more quickly. When comparing samples, identify the weave and coating as well as the fibre composition.

WHAT IS PVC TARPAULIN FABRIC?

PVC tarpaulin is a polyester-based fabric with a coated or laminated PVC surface. It is commonly used for tarpaulins, vehicle and lorry covers, furniture, machine covers and canopies. For a purchase enquiry, distinguish between raw fabric in rolls and a finished cover with its required dimensions and fixing details.

Explore PVC tarpaulin fabrics for the relevant application rather than choosing by material name alone.

SUN, WATER AND DIMENSIONAL STABILITY:

UV exposure

Both canvas and PVC are affected by UV radiation and can deteriorate during outdoor exposure. Greater UV stabilization can extend service life, with a corresponding increase in price. Compare the intended exposure and the selected material’s specification when evaluating outdoor covers.

Water resistance

Canvas is water resistant rather than waterproof: quality canvas resists water penetration to a degree under its intended conditions of use. A PVC-coated or laminated surface is useful for protective covers exposed to rain. For either choice, include seams, edges, fittings and the cover’s installation in the finished-product specification.

Shrinkage

Cotton canvas shrinks because of its natural fibres, while PVC fabric does not have this cotton-related shrinkage because its base uses synthetic fibres. Polycotton is less likely to shrink than cotton canvas. This distinction matters when ordering fitted covers or fabric cut to a particular shape.

FLAME-RETARDANT GRADES AND PROJECT REQUIREMENTS:

Canvas and PVC tarpaulin can be supplied in flame-retardant grades. The material name alone does not establish the finished fabric’s fire performance. A suitable formulation or finish can reduce flame propagation under specified test conditions; flame retardant does not mean fireproof.

PBDEs were historically used as flame retardants. Several PBDE groups, including decaBDE, are now listed in Annex A of the Stockholm Convention. A current specification should identify the proposed formulation’s applicable chemical requirements and supporting documentation.

For projects in Europe, the US or Australia, establish the fire requirements for the specific use and installation with the buyer or approving authority. There is no single blanket requirement for every canvas or PVC application. State the required standard, edition and acceptance criteria in the enquiry. For example, NFPA 701 addresses flame propagation testing of textiles and films; whether it is required depends on the project.

Flame-retardant treatment adds cost and can bring the price close to double that of an untreated option for some fabric and finish combinations. It should be specified rather than assumed to be included as standard. Compare quotations for the same base fabric, finish and required performance.

COST AND MATERIAL SELECTION:

Canvas generally costs more than PVC in this comparison because cotton fabric is more expensive than the plastic-based alternative. Final quotations also depend on the fabric construction, UV stabilization and flame-retardant finish. Choose canvas where its fabric feel and breathability suit the application; consider PVC tarpaulin for coated protective covers, lorry covers, machine covers and canopies.

For a detailed cost breakdown, send the application, material preference, weight, width, color, quantity and required finishes. Include any fitted dimensions or fire-performance standard. Request a fabric recommendation and quotation.

FAQ

What is the main difference between canvas and PVC tarpaulin?

Canvas uses cotton or polycotton fabric. PVC tarpaulin uses a polyester fabric with a coated or laminated PVC surface. The choice depends on the cover’s water exposure, breathability, fit, UV exposure and required finish.

Is canvas waterproof?

Water-resistant canvas resists water penetration under its intended conditions, but water resistance is different from waterproofing. Specify the fabric finish and the construction of the finished cover when rain protection is a priority.

Should I order flame-retardant canvas or PVC fabric?

Specify a flame-retardant grade when the application or project requires it. Provide the required test standard and acceptance criteria so the material and quotation can be matched to the project. Flame-retardant performance should not be assumed from the words canvas or PVC alone.
