Description
Technical field
The present invention relates to textile engineering technical field, more particularly to a kind of endowing terylene fabric high-hydrophilic and can reacting
The nitrification method of reducing of group.
Background technology
Dacron has prominent Practical Performance, is widely used in garment industry.One kind of polyster fibre is just
Account for the 40% about of all fibres, be most important chemical fibre.
But dacron is hydrophobic fabric, and when taking, poisture-penetrability is poor, sultry, uncomfortable.Therefore international and domestic with regard to
The research of terylene hydrophilic modifying is always focus.What research report was most at present is Plasma modification method, but, plasma
Modifies need high vacuum environment, equipment investment is high, and continuous production can be poor, high cost, and the hydrophilic of modified dacron is not
Have clear improvement, industrialized production difficulty is big；Potassium permanganate oxidation method then not only can produce pollution, the strength of dacron also can
It is subject to compared with macrolesion；Ultraviolet and ultraviolet/nano titanium oxide method then take more, and energy-output ratio is big, and exists
Hydrophilic wild effect；The hydrophilic of Alkali reduction method endowing terylene fabric is limited, and effect is not fine, and to dacron
Strength has certain impact.Frequently with hydrophilic compounds dip finishing in actual production, effect is good, but does not substantially have durability, and one
Wash just without hydrophilic.
Simultaneously as dacron does not have good health care to human body skin, accordingly, with respect on dacron surface
The research report being grafted various albumen is more.But, the polyester macromolecule of terylene almost do not have can reactive group, simply macromole
Two ends have hydroxyl, so, cross-linking agent to be passed through improves the health care of dacron in the various albumen of dacron surface grafting
Function, generally requiring first endowing terylene fiber surface can reactive group, such as hydroxyl, amino etc..The method of report has in height at present
The method inlaying hydroxy-containing compounds endowing terylene fiber surface oh group in terylene surface layer under warm high pressure, but the method needs
Want high temperature and high pressure environment, equipment investment high, and the hydrophilic of fabric does not almost improve；Plasma method can give simultaneously
PET fiber surface can reactive group and high-hydrophilic, but because its complex process, industrialized production difficulty are larger, operating cost
Height, thus also need to develop better method, not only can endowing terylene fiber surface high-hydrophilic but also can endowing terylene surface can be anti-
Answer group.
Content of the invention
An object of the present invention is that prior art processes are complicated, industrialized production difficulty is larger, operating cost in order to solve
High problem, provide a kind of simple to operate, endowing terylene fabric high-hydrophilic that operating cost is low and can reactive group nitrification
Method of reducing.
The present invention provide a kind of endowing terylene fabric high-hydrophilic and can reactive group nitrification method of reducing, including with
Lower step：
(1) dacron is impregnated in certain density dust technology certain time；
(2) take out the dacron being impregnated with dust technology, bakee certain time at a certain temperature；
(3) baked dacron is put in certain density sodium sulfide solution and reduce in a certain temperature conditions
Certain time；
(4) take out the dacron after reduction to carry out washing, be drying to obtain there is high-hydrophilic and can the washing of reactive group
Synthetic fibre fabric.
Further, the concentration that finite concentration described in described step (1) refers to dust technology is 5～50g/L, a described timing
Between refer to 1～20min.
Further, described in described step (2), uniform temperature refers to 70～100 DEG C, and described certain time refers to 7～20min.
Further, the concentration that finite concentration described in described step (3) refers to sodium sulfide is 10～30g/L, a constant temperature
Degree refers to temperature and is 70～98 DEG C, and certain time refers to 5～30min.
Know-why disclosed by the invention is：After dacron surface speckles with a certain amount of dust technology, in baking process,
Moisture in dacron is subject to thermal evaporation, and after moisture gradually evaporates, a small amount of concentrated nitric acid is only left on terylene surface, and concentrated nitric acid exists
Under certain temperature action, there is nitration reaction with the polyethylene terephthalate macromole in terylene, endowing terylene is fine
Dimension surface nitro groups；The terylene then with nitro is reduced in sodium sulfide solution, and nitro is reduced into amino, and amino has
Hydrophilic, thus both imparted terylene high-hydrophilic, impart terylene can reactive group-amino again.Dacron is passed through
The other functional compound of cross-linking agent grafting is thus endowing terylene fabric various functions are possibly realized.
The beneficial effects of the present invention is：The dacron of the technical program preparation will have high-hydrophilic and can be anti-simultaneously
Answer group, rather than only single hydrophilic or can reactive group；The water contact angle of fabric face is at 0～18.5 °, and has
There is durability.Meanwhile, fabric strength keeps good, and instrument equipment is common equipment, without high-temperature high-pressure apparatus or vacuum
Equipment etc., process is simple, cost is relatively low.
