Description
Technical field
The present invention relates to textile finishing technical field, more particularly to a kind of coloured flame-retardant polyester-cotton fabric and its preparation side
Method.
Background technology
Polyester cotton is so that its outward appearance is well-pressed, quick-drying washable, ventilative comfortable and the advantages of high intensity, is widely used in work
Protective garment, fire-entry suit, fight of army clothes, bedding and interior decoration fabric, the market share are huge.Polyester-cotton blend product needs mostly
Carry out flame-proof treatment to meet different degrees of fire prevention demand.However, as polyester cotton textile pure is washed more than single
Easy firing, and than single cotton component or wash that component is more violent when burning, therefore the flame treatment of polyester-cotton fabric is always industry
An interior difficult problem.The well accepted explanation of polyester-cotton blend more easy firing is that " tare effect ", i.e. cotton fiber burn to form charcoal frame, terylene burning
When depend in the above, special drainage effect aggravates whole combustion process.In recent years, though having a great deal of to this both at home and abroad
Trial, but still can not yet find maturation, can with commercial introduction metaplasia produce technique and formula.
The polyester-cotton fabric flame resistant method reported at present mainly has following three kinds：1) pad baking process.Such as using THPN,
THPC arranges polyester-cotton fabric with urea, TMM, it is possible to decrease the burn rate of polyester-cotton fabric, but there is release bad smell, smoke amount
Greatly, the shortcoming of Boardy Feeling；2) coating.There is report to point out, 65/35 plain weave polyester-cotton fabric is applied using bromine antimony fire retardant (CFA)
Layer is arranged, and can meet national standard, GB5455-85, but smoke density is larger when burning, and einnehmen function is restricted.And the series
Fire retardant disable at present.There is the drawbacks such as washing durability is low, strength declines simultaneously in above-mentioned flame-proof treatment.3) wash with fire-retardant
Synthetic fibre fiber blend.As the flame-proof treatment of polyester cotton is more difficult, therefore the polyster fibre and cotton with the right property of resistance can be adopted
Blending, then flame treatment is carried out to blend fabric with cotton fire retardant, preferable flame retardant effect can be obtained.Modified dacron is adopted such as
Fiber Trevira CS and cotton fiber blending, then to blend fabric flame treatment.But, the method is relatively costly, and product is simultaneously few
See.
In view of above-mentioned defect, the design people, positive in addition research and innovation, to founding a kind of novel colored fire-retardant wash
Bafta and preparation method thereof so as to more the value in industry.
The content of the invention
To solve above-mentioned technical problem, it is an object of the invention to provide a kind of coloured flame-retardant polyester-cotton fabric and its preparation side
Method, based on biomass modified, raw material environmental protection is easy to get the coloured flame-retardant polyester-cotton fabric of the present invention, good flame retardation effect, can lift fabric
Physical and mechanical properties, is easy to industrialized production.
The preparation method of a kind of coloured flame-retardant polyester-cotton fabric of the present invention, it is characterised in that comprise the following steps：
(1) polyester-cotton fabric is impregnated in aqueous dopamine solution at 35-40 DEG C, then takes out polyester-cotton fabric, washing is simultaneously
Drying, obtains coloured polyester-cotton fabric；
(2) the coloured polyester-cotton fabric for obtaining step (1) is impregnated in the phytic acid sodium water solution that pH value is 2～3, and drip washing is simultaneously
Drying；Then by drying after coloured polyester-cotton fabric impregnate in the chitosan aqueous solution that pH value is 5～5.5, drip washing is simultaneously dried；
(3) the coloured polyester-cotton fabric after step (2) process is alternately soaked in phytic acid sodium water solution and chitosan aqueous solution
Stain 15-20 time, and drip washing, drying after impregnating every time, are carried out to coloured polyester-cotton fabric, obtain coloured flame-retardant polyester-cotton fabric.
Further, in step (1), the fiber quality ratio of polyester-cotton fabric to wash 10%～80%, cotton 20%～
90%.
Further, in step (1), the concentration of aqueous dopamine solution is 1.5-2.5g/L.
Further, in step (1), polyester-cotton fabric is soaked into 16-24h at 35-40 DEG C.
Further, in step (1), the color of coloured polyester-cotton fabric is different degrees of brown to brown.
Further, in step (2), the mass fraction of phytic acid sodium water solution is 1.5～2%.
Further, in step (2), the mass fraction of chitosan aqueous solution is 1～1.5%.
Further, in step (2), the molecular weight of shitosan is 20,000-50 ten thousand g/mol.
Further, in step (2), coloured polyester-cotton fabric impregnates 10-15min in phytic acid sodium water solution, poly- in shell
5-8min is impregnated in sugar aqueous solution.
Further, in step (3), during alternating impregnating, 5-8min is impregnated every time.
The present invention is claimed the coloured flame-retardant polyester-cotton fabric prepared using said method simultaneously.
Further, the radial fragmentation strength of coloured flame-retardant polyester-cotton fabric is 265.6N～333.6N.
The principle of the present invention is as follows：Because component and the respective physicochemical properties of cotton component are washed in polyester cotton not
Same, fine structure is different, so two kinds of components are differed greatly with the reactivity of fire retardant.The present invention is using extremely strong more of adhesiveness
Bar amine carries out surface and is modified to which, equivalent to the platform of secondary response in polyester-cotton fabric surface construction.Polyester-cotton fabric surface by
Containing abundant hydroxyl and amino in the poly-dopamine of dopamine autohemagglutination, under certain pH value condition, difference can be presented
Charge property.In the present invention, in phytic acid sodium water solutions of the pH for 2-3, polyester-cotton fabric carries positive charge, and with negative electrical charge
Phytic acid radical ion produce electrostatic interaction, further pH for 5-5.5 chitosan aqueous solution in, surface for negative electrical charge phytic acid
Further there is Electrostatic Absorption with the shitosan with positive charge in root, so alternately, the addition of fire retardant is reached necessarily
Value, so as to produce corresponding target flame retardant effect.
By such scheme, the present invention at least has advantages below：
The raw material of the present invention is biological material, and dopamine, sodium phytate, shitosan are environmentally friendly raw material, thereby, it is ensured that
The security and raw material environment friendly of the chemicals for using of the invention, operation are easy to carry out, and energy consumption is low；Made by the present invention
The strength of polyester-cotton fabric is unaffected, has been lifted than the strength of undressed polyester-cotton fabric on the contrary, this be because phytic acid root with
After the layer assembly of shitosan, caused by polyester-cotton fabric surface generates the assembling coating of stronger electrostatic interaction.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
