FABRIC FOR CLEARSPAN FABRIC STRUCTURES

Fabric Introduction


1. Material Analysis

Fabric is a material synthesised from base cloth, coating and surface treatment. The base cloth is the main structure of the fabric, which plays an important role in the tensile strength and abrasion resistance of the fabric. Common fabric base cloth materials include polyester fibre, polyamide fibre, glass fibre and polypropylene fibre. In the base cloth through the coating treatment, after the coating can make the fabric with waterproof, sunscreen, wear-resistant, anti-corrosion and other properties. Common fabric coating materials are PVC (polyvinyl chloride), PE (polyethylene), PU (polyurethane), PVDF (polyvinylidene fluoride), etc., and their selection should be based on the actual use requirements and environmental conditions.

In the awning industry, PVC fabric is most used, the main factors are as follows:

  • Strong weather resistance: PVC fabric has excellent weather resistance, able to resist the effects of sunlight, rain, wind and other external environments, and can be used for a long time under different geographical and climatic conditions without damage.
  • Good fire resistance: PVC has good fire resistance performance, can effectively flame retardant, reduce the risk of fire. This enables PVC fabrics to provide extra security in tents.
  • Strong chemical resistance: PVC has good chemical resistance and can resist the corrosion of some chemicals, which makes the clear span more durable in specific operating environments.
  • Convenient construction: PVC fabric is soft and easy to process, can be cut and sewn according to the specific needs of the tent, while maintaining a certain degree of foldability, easy to set up and dismantle.
  • High tensile strength: PVC fabric has high tensile strength and can withstand large tensile force, making the tent have good stability and structural strength.
  • Low price cost: price advantage for large-scale application

In order to increase the aesthetics and softness of the fabric, surface treatment is required. Common surface treatment methods used are shaping, calendering, embossing and so on. Through different surface treatment methods, the appearance of the fabric can be made smoother and more beautiful, and at the same time, the comfort and softness of the fabric can also be enhanced.

Fabric Connection:

  • For the regular side cloth connecting method, there are mainly open type: chicken eye buckle with tie rope, zip; not open type: the whole side cloth.
  • In order to cater for the exhibition activities, the design of open side cloth can provide a more spacious and transparent environment for the exhibition venue, so that the participants can freely enter and exit the exhibition area, and increase the convenience of interaction and communication.
  • The design of open side cloth can adopt materials with ventilation and light transmission, such as mesh cloth or transparent material. This not only facilitates access, but also maintains indoor and outdoor air circulation to avoid stuffiness and discomfort.
  • One way.
    Side cloth with chicken eye buckle with tie rope, taking into account the exhibition activities when the side cloth is frequently used in this form with tie rope is more solid, not easy to damage;
  • The side cloth is equipped with zip, due to the use of zip, there is excessive stretching and tearing, we generally require regular replacement of the zip head, regular cleaning of the zip to prevent dust, dirt or other impurities, as well as regular lubrication and maintenance;
  • Whole Side Fabric
    Transparent Square/Round Window Transparent square/round windows are designed to provide a bright atmosphere and good ventilation to the interior space and facilitate interaction and connection with the outdoor environment.
  • Velcro waterproof cover cloth
    When the diagonal beams are spliced in two or more pieces (e.g. spanning 25 metres or more or variable tents), the diagonal beams will inevitably leak at the splicing position;
  • For different clear span use, the temporary solution: the joints are coated with structural adhesive or butyl tape is attached to the diagonal beam joints;
  • For a long-term solution to roof leakage, a fabric can be added to cover the pitched beams;
