摘要
The purpose of this research was to improve flame retardancy and anti-dripping of polyester fabric by using bentonite, 3% (w/w) diammonium hydrogen phosphate (DA) and 5, 10% (w/w) aluminium hydroxide (Al(OH) 3 ) via pad-dry technique. The burning behavior of the treated polyester fabric was investigated according to ASTM D1230. The results showed that 10wt% of bentonite alone were capable of imparting anti-dripping. Nevertheless, the preparation of the slurry of bentonite (>10% (w/w)) caused high viscosity leading to difficulties for the preparation and finishing process. Thus, the addition of 4% (w/w) of sodium chloride (NaCl) to the suspension of bentonite (up to 25% (w/w)) resulted in lower viscosity of the slurry, which led to an easing of the preparation and finishing process. It was found that the flame retardancy and anti-dripping PET fabric treated with bentonite and NaCl could perform slightly better than the untreated one while the fabrics treated with DA or Al(OH) 3 alone exhibited no melt drips. However, the treated fabric with bentonite (over 10% (w/w) up to 20% (w/w)) mixed with 3% (w/w) DA or 10% (w/w) Al(OH) 3 mixed with bentonite showed safer flaming drip than the untreated one.
