Background technology
Dacron has good brute force, ABRASION RESISTANCE, stiffness, DIMENSIONAL STABILITY and good well-flushing truck, being widely used in garment material because of it.But terylene is a kind of typical hydrophobic fibre, and regain is only 0.4%, even if hydroscopicity also only has 0.6%-0.8% under 100% relative humidity.As skintight suit material, especially its perspire difficulty when perspiring, to the sensation of the sultry discomfort of people; As coat fabric, in wearing process, with air or health friction, easily produce charge collection and attract dust.The hygroscopicity difference of terylene and electrostatic problem have a strong impact on its wearability and industrial expansion.
In order to obtain polyester fiber or the fabric of excellent hydrophilic and antistatic behaviour, researcher carries out a large amount of research work.At present, improve dacron wearability and mainly contain two kinds of methods: one is utilize the synthetic technology of fiber in spinning process, add hygroscopic agent or antistatic additive carries out modification to polyester fiber structures, gives fabric hydrophilic, antistatic, decontaminable performance.Two is utilize fabric post-treatment technology on polyester macromolecule chain, introduce hydrophilic radical or anti-static function molecule, makes terylene surface form hydrophilic protective layer and conductive layer, reaches and change fiber surface hydrophily and antistatic behaviour.Spinning modified dacron hydrophily and antistatic behaviour good endurance, wherein hydrophilic component composite spinning, heteromorphosis, microporous and modification of graft etc. drop into suitability for industrialized production in various degree.But its complex process, and on the physical property of terylene and spining technology impact very large.Arrangement modifying production process is simple, but poor durability.How to improve the problem that its durability arranged is extremely urgent.
Reported method mainly contains and arranges with highly basic hydrolysis (Alkali reduction), hydrophilic finishing agent absorption set method, surface grafting polymerization and film.All there is certain problem in these methods, as: Alkali reduction speed is wayward, and brings environmental problem, and its waste water produced is the novel waste water that dyeing intractability is larger; Hydrophilic finishing agent absorption set method subject matter is hydrophilic poor durability after surface treatment; Surface grafting method is more difficult carries out, and cost cost is higher, treatment process more complicated; Film arranges mainly natural polymer such as the coating of silk gum, wool keratin and arranges, but its durability is also not high.The present invention intends adopting the ester bond in microwave radiation technology alcoholysis technology local failure polyester fiber, forms hydrophilic group, to when without finishing agent, obtains surface hydrophilicity dacron.
