Abstract

The mend for fabric products has been increased remarkably with increasing population, housings, mutistory buildings,...and etc. during the last two decades. However, since fabrics are highly combustible and can produce toxic gases during the combution, fabric products can result in serious human injury as well as financial damage. Acknowledged by this, a new phosphorus based flame retardant suitable for PET fabric has been synthesized by making use of the reaction of diphenyl chloro phosphate and hexamethylenediamine. Since the starting meterials are relatively cheap and the yield of this reaction is high (more than 90%), this reaction seems to be very effective as wall as very economic. By analyzing various spectrophotometric analysis data such as NMR, FT-IR, and Mass, this new flame retardant is identified to be N,N’-Bis(diphenyl chlorophosphoro)diamino hexane. In the mean time, DSC measurement has shown that the melting point and the boiling point of this material are around 115$^{\circ}C$ and around 40$0^{\circ}C$, respectively. The flame retardancy test done on the PET fabric processed by this flame retardant have shown excellent in times of flame contact, times of flame contact for washable. The most economical finishing condition estimated 10% in concentration of BDPDH, Moreover, it has been also found that the drape stiffness of the PET fiber processed by the flame retartant is changed very litter compared to the unprocessed original PET fabrics. Judging from this, the potential of this new phosphrdus based compond as a flame retardant for PET fabric seems to be high.
