Detailed Information on Parachute Fabric for Backpack Manufacturing for Sewing Professionals

Parachute fabric for backpack manufacturing is a high-tech material widely used in the modern bag manufacturing industry. May Hợp Phát will provide a comprehensive guide for sewing industry professionals, backpack manufacturers, and DIY enthusiasts.

Through this, you will master the technical characteristics of parachute fabric types, appropriate selection criteria for each purpose, and specialized techniques to create durable and beautiful products that meet high-quality standards.

I. Common Types of Parachute Fabric for Backpack Production

1. Polyester Parachute Fabric

Polyester parachute fabric is one of the most popular choices for backpack production thanks to its excellent balance between cost and performance. This material stands out with:

• High mechanical durability: Withstands tensile force, compression force, and good abrasion resistance
• Moisture resistance capability: Does not absorb water, dries quickly after water contact
• Reasonable price: Lower production costs compared to nylon while still ensuring quality

Common polyester fabric codes for folding backpack manufacturing include 600D, 900D, 1200D, and 1680D. Among these, 600D fabric is commonly used for student backpacks, while 1680D is for premium travel backpacks requiring high durability.

Polyester parachute fabric is particularly suitable for everyday backpacks, laptop bags, and sports backpacks thanks to its good shape retention and easy processing.

2. Nylon Parachute Fabric

Nylon parachute fabric is a premium fabric line in the parachute fabric family with many outstanding advantages:

• Extremely high durability: Superior to polyester in load-bearing capacity
• Lighter weight: 15-20% lighter than polyester at the same thickness
• Good elasticity: Less wrinkling and better shape recovery capability

Compared to polyester, nylon has a higher price but provides commensurate value through durability and weight. Nylon parachute fabric is commonly used to manufacture specialized backpacks for trekking, mountain climbing, and professional outdoor activities.

3. Oxford Parachute Fabric

Oxford parachute fabric with its special weaving structure creates unique characteristics:

• Smooth fabric surface: High flatness and softer touch feeling
• Good waterproof capability: Especially after PU or PVC coating
• High aesthetics: Beautiful surface, suitable for premium products

Oxford fabric is produced in various codes from 210D to 1680D depending on usage needs. This fabric type is commonly applied in fashion backpack lines, business backpacks, and premium backpacks thanks to its luxurious appearance.

4. Ripstop Parachute Fabric

Ripstop fabric with its special reinforced structure is an excellent choice for products requiring high durability:

• Anti-tear technology: Reinforced fibers woven in square patterns create superior tear resistance
• Light weight: Lighter than conventional fabric with the same durability
• High flexibility: Easy to fold and store without wrinkling

Ripstop fabric is commonly used in areas bearing large loads in backpacks such as the bottom, straps, or for the entire backpack when weight reduction is needed while ensuring durability.

II. Technical Specifications of Parachute Fabric

1. Thickness (Denier) and Its Meaning

The Denier (D) parameter is the most important index when evaluating parachute fabric. It measures fiber density and directly affects the fabric’s durability, weight, and feel.

• 210D-420D: Thin, light fabric, suitable for lining layers or small compartments
• 600D-900D: Balance between durability and weight, suitable for student and office backpacks
• 1000D-1200D: High durability, used for travel backpacks, sports backpacks
• 1680D and above: Extremely durable, used for specialized backpacks, industrial backpacks

Choosing the appropriate Denier helps optimize the balance between product durability and weight. Higher thickness provides greater durability but also increases weight and cost.

2. Coating Technology and Surface Treatment

Parachute fabric is often treated with special surfaces to enhance technical characteristics:

• PU (Polyurethane) Coating:
  • Creates a thin, flexible membrane on the fabric surface
  • Effectively increases waterproof capability
  • Maintains fabric softness
• PVC (Polyvinyl Chloride) Coating:
  • Creates a thicker, harder coating than PU
  • Absolute waterproof capability
  • Increases durability and abrasion resistance
  • Reduces softness, increases weight

• DWR (Durable Water Repellent) Technology:
  • Creates a water-repellent surface without reducing breathability
  • Water forms droplets and slides off the fabric surface
  • Lighter than PU and PVC
• UV Protection Treatment:
  • Prevents ultraviolet rays from damaging fabric fibers
  • Minimizes fading when used outdoors
  • Extends product lifespan

3. Durability and Load-Bearing Capacity

Fabric durability is evaluated through various technical parameters:

• Tensile strength: Measures load-bearing capacity before breaking
  • 600D fabric: 40-50kg/cm²
  • 1200D fabric: 70-90kg/cm²
  • 1680D fabric: 100-120kg/cm²

• Abrasion resistance: Friction resistance capability
  • Measured by number of rotations before fabric wears out
  • Nylon > Polyester > Common fabrics
• Expected lifespan:
  • Frequent use: 3-5 years with 600D, 5-7 years with 1200D
  • Light use: Can extend beyond 10 years with high-quality parachute fabric

III. How to Choose Appropriate Parachute Fabric for Each Backpack Type

1. Travel and Outdoor Backpacks

Travel and outdoor backpacks have specific technical requirements:

• Can withstand large weight: Must often contain many heavy items
• High durability: Use in harsh conditions, frequent friction
• Good waterproof capability: Protect belongings in bad weather conditions

Most suitable parachute fabric for this segment:

• Nylon Ripstop 1000D-1680D with double PU coating
• Polyester 1200D-1680D with PVC coating for cheaper backpack lines
• Oxford 1680D with PU coating for premium, luxurious travel backpacks

2. Student Backpacks

Student backpacks require balance among multiple factors:

• Reasonable price: Suitable for students’ financial capabilities
• Moderate durability: Only needs to withstand the weight of books and laptops
• Aesthetics: Diverse design and colors, suitable with trends

Suitable parachute fabric:

• Polyester 600D-900D with PU coating: Balance between cost and durability
• Oxford 600D: Beautiful appearance, suitable for premium student backpacks
• Polyester 300D-420D: For light, simple backpack lines

3. Fashion Backpacks

For fashion backpacks, aesthetic factors play a decisive role:

• Beautiful fabric surface: Bright, even colors, good touch feeling
• High flatness: Creates standard form, no wrinkles
• Color retention capability: Does not fade after usage time
