Description
Technical field
The preparation method who the present invention relates to a kind of antibacterial Regenerated Polyester Fibres, belongs to field of polymer material preparing technology.
Background technology
Polyester is whole world consumption maximum, purposes one of macromolecular material the most widely, relies on its superior performance, has been widely used in the fields such as textile fabric, packaging material and film medium.It is very poor that yet polyester and fiber thereof have stronger hydrophobicity, be difficult to give polyester fiber with antibacterial functions, limited its application in fields such as weavings of polyester fiber, by physico-chemical process, polyester fiber has been carried out to an antibacterial modified important research direction that has become Speciality Pet Fiber production and scientific research.
The polyester product with anti-microbial property is that people pay close attention to and research object all the time.This series products often with human body intimate contact, therefore requirement has following characteristics: (1) has broad spectrum antibacterial and stronger sterilizing ability; (2) non-stimulated to human body, without irritated; (3) fiber after antibacterial has durability; (4) on the not impact of the outward appearance of fiber; (5) processing method is simple, can be suitable for suitability for industrialized production.
The preparation method of antibacterial polyester fibre mainly contains two kinds at present, and first method is to adopt the dressing liquid that contains anti-biotic material to carry out rear arrangement to polyester fiber to obtain antibacterial polyester fibre.
China Patent Publication No. CN102517888A, open day is on September 4th, 2013, discloses a kind of manufacture method of antibacterial moisture transmitting polyester fiber.This invention adopts alkali decrement treatment technology to introduce hollow and cavity in polyester fibre surface, and nanometer silver antimicrobial particle is combined with polyester fibre surface, and the antibacterial functionalized and hydrophilicity-imparting treatment of fiber is united two into one, and has technique simple, the feature that cost is low.
Above-mentioned weak point is for example by the mode of cast setting, nano-Ag particles to be combined with fiber surface the wash durability of antibacterial polyester fibre is declined, anti-microbial property stability can not guarantee, because surface of polyester has formed a lot of hollows, the mechanical strength of fiber has been weakened much simultaneously; Post processing meeting produces a lot of waste liquids in addition, and environment is caused to certain pollution.
Second method is to have metal or oxide powder or quaternary ammonium salt antiseptic etc. and the polyblend of antibacterial functions, to be then spun into fiber.
China Patent Publication No. CN103147164A), open day is on June 13rd, 2013, discloses a kind of antibacterial efficient blend ester fiber and preparation method thereof.This invention will contain the functional agglomerate of nano silver material, water-soluble polyester section, and PTT section and terylene chips carry out blend melt spinning and obtain antibacterial efficient blended fiber, and this technique simple application is extensive, and fiber has antibacterial far infrared and breathes freely and lead wet effect.China Patent Publication No. CN102433603A, open day is on May 2nd, 2012, discloses a kind ofly to have from hydrophilic anti-bacterial wet-absorbing sweat-repellent polyester fiber.This invention by hydrophilic modifying polyester master particle, contain Ag-Cu-Zn particle carrier antibacterial polyester masterbatches and copolymerization polyester master particle is prepared antibacterial polyester fibre by the method for co-blended spinning, this kind of fiber has good moisture absorption and leads sweat and bactericidal property.
Above-mentioned two kinds of method weak points are that in these class methods, powder is easy to reunite in polymer, stop up spinneret orifice, and spinnerets shortens service life, and equipment cost rises, and the outward appearance of this outer fiber or textiles, mechanical strength reduce.The acquisition of antibacterial functions depends on antiseptic to the speed of top layer migration, so the speed of this type of anti-bacterial fibre sterilization is slow.
China Patent Publication No. CN102102240A), open day is on June 22nd, 2011, discloses a kind of antibacterial polyester fibers and manufacture method thereof and purposes.This invention is carried out blend melt spinning by polyester and water-insoluble quaternary ammonium salt according to certain ratio, obtains antibacterial polyester fibre, has good heat resistance, water-wash resistance and lasting anti-microbial property.
Above-mentioned for example weak point is that blend has the polyester fiber hydrophily of water-insoluble quaternary ammonium salt poor, to bacterium to kill speed slow, time that need to be longer.
