company news about Flame retardant knitted fabrics: the "invisible guardians" of the lining world

Invisible Safety Barriers

• Ordinary lining: soft and comfortable but flammable and can be an "invisible accelerant" in a fire.
• Flame-retardant knitted fabric lining: hidden under the outer fabric, it instantly "freezes" the spread of flame in case of fire, guarding the last line of defence.

Part I: Three core advantages of flame retardant knitted fabric lining

1. Flame retardancy: the "emergency brake" on flames.

- technology principle:
• Fibre-level flame retardant: cotton/flame retardant fibre blends (e.g. Aramid 1313 or Modal FR), which form a dense carbonised layer when burning, blocking oxygen.
• No Melt Drops Design: passes GB/T 17591 standard, no melt drops in case of fire (to avoid secondary burns).
- Performance Data:
• Vertical combustion test: damage length ≤ 8cm, renewal time 0 seconds (traditional chemical fibre liner damage length > 25cm);
• Limit temperature: short time to withstand 300 ℃ high temperature (such as welding spark splash scene).

2. Comfort: safety ≠ sacrifice experience

- Breathability and moisture removal:
• Knitted structure breathability >3500g/m²/24h, humidity regulation ability is 40% higher than woven fabric;
• Firefighting suit liner actual test: 4 hours of continuous operation, inner layer humidity reduced by 50%, body temperature reduced by 3℃.
- Soft fit:
• 40S high count yarn + double-sided knitting process, bending stiffness <0.5cN/cm² (close to cotton T-shirt touch).

Part II: Application Scenarios and Cases

Scenario 1: Home upholstery lining - the "gentle colour" of safety

- Case: High-end sofa fire-retardant lining co-operation project
• Requirement: The sofa filling sponge needs to meet the British BS 5852 fire standard, but the traditional non-woven fabric lining is flammable and easy to age. o Solution: 220g/m² flame retardant knitted fabric lining.
• Solution: 220g/m² flame-retardant knitted fabric lining + flame-retardant foam composite structure.
• Result:
  Open flame test: self-extinguishing within 30 seconds after contact with an ignition source, smoke toxicity class 1 (lowest hazard);
  Customer feedback: sofa service life extended by 3 years, return rate reduced by 80%.

Scenario 2: Traffic seat lining - the "invisible insurance" on the journey

- Case: New energy bus seat upgrade
• Challenge: Seats need to pass EN 45545-2 R22 fire rating and withstand 100,000 times of extrusion friction. o Innovation: Double-layer flame retardant knitted fabric lining (outer layer moisture wicking/inner layer fire resistant).
• Innovation: Double-layer flame retardant knitted fabric lining (moisture wicking outer layer/fire retardant inner layer) + high elasticity foam.
• Effect:
  Heat release from combustion <3MJ/m² (standard limit 15MJ/m²);
  Abrasion test up to 150,000 times, seat collapse rate <5% (industry average >20%).

Let safety be embedded in every level of detail.

  "True security is not in the glamour of appearances, but in the extreme guarding of every layer of detail."
