Many dyeing mills have switched to fluorine‑free water repellents. They want to meet EU PFAS bans. But then a new problem appears. The fabric stops repelling water after just a few washes. Before washing, the sample passes customer inspection. After washing, it fails. Then customers reject the goods or demand compensation. Some export orders get cancelled because the brand requires high wash durability.
For example, a large mill in Jiangsu Province faced this exact issue. The customer demanded 90 points before washing and 80 points after 5 washes. They tried many products but could not reach stable results. Then the technical team from Lianzhuang technology came to the mill with TEXNOLOGY®M630 fluorine‑free Anti-Wicking waterproofing Agent. They ran on‑site trials.
TEXNOLOGY®M630 fluorine‑free Anti-Wicking waterproofing Agent breaks the curse of “fluorine‑free means poor wash durability”.
TEXNOLOGY®M630 is an eco‑friendly polyurethane‑based fluorine‑free water repellent. It contains no fluorine and no APEO emulsifiers. Its molecular structure gives both performance and environmental safety.
First, it offers excellent wash durability. After repeated home laundering, it keeps high water repellency. It shows very little yellowing. It does not affect fabric hand feel. It even reduces “white finger marks” on the fabric surface. Take the Jiangsu mill again. They make polyester‑cotton fabrics. Their requirement: 90 points initial, 80 points after 5 washes. The Lianzhuang team brought TEXNOLOGY®M630 plus crosslinker GFF to the mill. Process: one dip and one nip (pressure 3 kg), then dry and cure at 160°C for 3.5 minutes. Result: TEXNOLOGY®M630 at 10% plus 2% crosslinker GFF worked best. Initial water repellency scored 90 points. After 5 washes and drying, it still scored 85 points. This fully met the strict requirement.
Second, it is safe for the environment and for export. No fluorine. No APEO. It complies with EU and US regulations. So it acts as a safety pass for export orders.
Third, it gives excellent water repellency and strong anti‑wicking. Water beads roll off and do not penetrate. It stops water from climbing up the polyester‑cotton fabric. Also, it makes stains like coffee or tomato sauce easy to clean.
Moreover, TEXNOLOGY®M630 works on many applications. It suits all kinds of synthetic and natural fiber fabrics. Typical uses include outdoor windbreakers, work uniforms, children’s wear, rainwear, backpack webbing, garment tapes, labor‑protective gloves, outdoor gear, shoe materials, and umbrellas.
