Description
Technical field
The present invention relates to a kind of flame retardant cationic dyeable polyester fiber and manufacture method thereof.
Background technology
It is high that polyester fiber (being terylene) has intensity, good springiness, and wrinkle resistance is strong, dimensionally stable, ABRASION RESISTANCE is good, stable chemical performance, quick-drying washable, the performances such as heat resistance and weather fastness are good, so leapt to as global output maximum most widely used fiber species since modern age.But because the limited oxygen index of common PET is 20～24, can under usual conditions, burn, and also can melting drip under burning or high temperature, thereby limit its application in aviation, public place of entertainment, family's decorations art work and some special industry occasion.
Fire-retardant polyester fibre mainly makes by following several method at present, and the first is processed with fire retardant on the surface of fiber; The second is to add fire retardant to carry out blending and modifying; The third is to use fire proofing to carry out copolyreaction.Although having superiority on manufacturing cost, first method has the not shortcoming of the poor durability such as wash resistant; Second method, owing to having added fire retardant, exists viscosity and color distortion, may cause the problems such as the bad and physical property reduction of spinnability; The third method is to manufacture flame retardant polyester by copolyreaction, and its durability of fire-retardant is good, good spinnability and have physical and mechanical properties preferably.
Aspect fire retardant, a lot of patents have all related to the fire retardant of halogen system.Although this based flame retardant, after interpolation, can play flame retardant effect preferably really, have quite serious shortcoming: the color variation of polymer, light fastness reduces, and produces toxic gas, major polluting atmosphere environment in combustion process.Phosphorus flame retardant has overcome some shortcomings of halogen flame, and not only flame retarding efficiency is high, and can effectively reduce the release of corrosion or toxic gas.
From the phosphorus flame retardant combination, divide, a kind of is directly with main chain, to be combined and to form main chain phosphorus to also have a kind of be to be combined formation side chain phosphorus with side chain with phosphorus atoms with phosphorus atoms, flame retardant effect be take main chain as excellent, but the add anti-dyeability and the anti-hydrolytic performance that make polyester of side chain phosphorus fire retardant are better than main chain phosphorus.At present the side chain phosphonium flame retardant is mainly by preparing phosphorous epoxy resin, P elements to be introduced, wherein with
10-oxidation-(9,10-2 hydrogen-9-oxygen-10-phosphorus) assorted luxuriant and rich with fragrance (DOPO) is excellent, because be firm ring phosphorus structure, is a fire retardant that character is pretty good.Because the hydrogen of P-H in the DOPO structure is an active atomic, DOPO directly can be imported to the main body of epoxy resin, relate to a kind of side chain phosphorus fire retardant in patent CN200410084108.X,
This fire retardant is to adopt DOPO and itaconic acid (ITA) or its derivative to carry out the meter Xie Er addition to synthesize, and still, due to the existence of the methylene that is connected with phosphorus atoms, makes side chain elongated, and phosphorus atoms and main chain are distant, and fire resistance is affected; Introducing with duration side chain phosphorus fire retardant makes the polyester macromolecule short texture, and structural regularity is influenced, makes its crystallization difficulty, melting point depression, shaping and the physical property of impact silk; And the synthetic cost of itaconic acid and derivative thereof is higher.
Because the PET molecular structure is regular, degree of crystallinity and the degree of orientation are higher in addition, without easily dying functional group, polarity is less, lack hydrophily, the gap that there is no suitably to hold dye molecule between the polyester long-chain molecule, so dye particles is difficult for entering fiber, its dyeability is poor, can use the kind of dyestuff few, can only adopt the methods such as DISPERSE DYES carrier dyeing, high-temp dyeing and pad-dry-cure dyeing, but the working condition harshness, production cost is high, and product colour is undesirable.
Summary of the invention
