1. Fabric wool effect
The penetration of flame retardant into the fabric has a great influence on the durability of flame retardant fabrics. If the fibers inside the fabric do not contain enough flame retardant, even if the fabric has sufficient weight gain, the oxygen index of the flame retardant fabric will still be very low, and the flame retardant performance will decrease rapidly after washing. When the wool effect of the fabric is very low, even after 1 wash, the oxygen index is 8 cm/(30min), the flame retardant and washability is greatly improved, and even after 12 washes, the oxygen index is still > 28%, meeting the flame retardant standards.
2. The amount of flame retardant
The amount of flame retardant is too small to achieve the flame retardant effect; when the amount of flame retardant is enough, after washing 12 times, the Oxford cloth will The flame retardant properties of flame retardant fabrics are better, but the strength of the fabrics decreases a lot, the hand feels hard and sticky, which affects cross-linking and the flame retardant durability decreases; only when the amount of flame retardant reaches a certain standard, the fabric can have good flame retardancy. , can meet the standard requirements.
3. Dosage of cross-linking agent
In principle, any thermosetting resin that can cross-link with flame retardants and fibers can be used, but in actual application, the fixing temperature, fixing temperature and Factors such as time and feel. The amount of cross-linking agent basically does not affect the flame retardant properties of woven fabrics, but it has a great impact on the feel, tear strength and durability of flame retardant fabrics.
4. Baking temperature
When the baking temperature is lower than 140℃, the tearing strength of the fabric is better, but the flame retardancy and wash resistance are not good; When the temperature is higher than 180°C, the strength of the fabric decreases greatly, which affects the wearing performance; when the baking temperature is higher than 150°C and less than 175°C, the flame retardant and washability of the fabric is better, but the tearing strength is reduced to a certain extent. .
