Polyester is widely used in curtains, decorative fabrics, non‑wovens, and webbing. It offers good strength and cost‑effectiveness. But polyester is thermoplastic. It melts and burns when exposed to fire. It also produces molten drips that spread flames and stick to skin, causing severe burns. So flame‑retardant finishing has become a must‑have for safety.
In practice, however, mills often face several problems:
- Poor wash durability – many agents fail after a few washes.
- Stiff hand feel – coatings make fabrics rough and hard.
- Color changes – finishing alters shade or causes bleeding.
- Complex processes – some agents require special equipment or long curing times.
- Environmental concerns – halogenated agents and formaldehyde release are increasingly restricted.
Liangzhuang technology developed TEXNOLOGY®ZRJ washable flame retardant agent for polyester to solve these problems. It is specially designed for pure polyester fabrics. It offers low dosage, high efficiency, good wash durability, and environmental safety.
Core advantages of TEXNOLOGY®ZRJ
Low dosage, high flame retardancy
What worries mills most? Trial and error, rework, waste. TEXNOLOGY®ZRJ works effectively. At high temperatures, the agent melts or carbonizes rapidly. It forms a protective layer on the fabric surface. This layer blocks flammable gases and slows heat transfer. It turns ordinary polyester into a non‑flammable or difficult‑to‑ignite material. This significantly delays fire spread.
Keeps fabric style, no color change or bleeding
Treated fabrics retain their original strength and hand feel. There is no color change, bleeding, or staining. This is true “flame retardancy without trace.” For high‑end fabrics, this means you meet safety standards without losing quality or appearance.

3.Works with padding or exhaustion processes
TEXNOLOGY®ZRJ is not picky about equipment. It fits normal dryers or stenters. Process parameters are wide‑ranging. It works for both continuous large‑scale production and small batches. Quick start‑up and stable operation.
Eco‑friendly and safe
TEXNOLOGY®ZRJ has low volatility, is halogen‑free, and contains no banned substances. It meets chemical storage and transport safety standards. Workers handle it with peace of mind. Exporters face fewer barriers. It combines safety and sustainability.
Applications of TEXNOLOGY®ZRJ
This agent suits all types of pure polyester fabrics. It is especially recommended for polyester curtains, non‑wovens, decorative fabrics, webbing, and felt. Whether for home textiles, industrial fabrics, or garment accessories, TEXNOLOGY®ZRJ helps upgrade product safety and opens doors to premium markets.
Choosing an efficient, eco‑friendly, and washable flame retardant is a critical step for mills to raise product competitiveness and meet safety standards. TEXNOLOGY®ZRJ offers low dosage, high performance, and durability. It makes flame retardancy durable without sacrificing quality.
