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 sides
Method.
Background technology
The advantages that polyester cotton is well-pressed, quick-drying washable with its appearance, comfortable and intensity of breathing freely is high, is widely used in labour
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
Flame-proof treatment is carried out to meet different degrees of fire prevention demand.However, being washed more since polyester cotton is purer than single pure cotton
Easy firing, and than single cotton component or wash that component is more violent when burning, therefore the flame retardant treatment of polyester-cotton fabric is always industry
Interior problem.Well accepted explain of polyester-cotton blend more easy firing is " tare effect ", i.e., cotton fiber burns to form charcoal frame, terylene burning
When depend in the above, special drainage effect aggravates entire combustion process.In recent years, though having both at home and abroad to this great deal of
Trial, but still can not yet find it is ripe, can be with technique and formula that commercial introduction metaplasia is produced.
The polyester-cotton fabric flame resistant method reported at present mainly has following three kinds：1) baking process is padded.Such as use THPN,
THPC arranges polyester-cotton fabric with urea, TMM, can reduce the burn rate of polyester-cotton fabric, but there is release bad smell, smoke amount
Greatly, the shortcomings that 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 arranges, and smoke density is larger when can meet national standard, GB5455-85, but burn, and einnehmen function is restricted.And the series
Fire retardant disabled at present.Above-mentioned flame-proof treatment exists simultaneously the drawbacks such as washing durability is low, strength declines.3) it is washed with fire-retardant
Synthetic fibre fiber blend.Since the flame-proof treatment of polyester cotton is more difficult, therefore can be used has had the polyester fiber for hindering right property and cotton
It is blended, then flame retardant treatment is carried out to blended fabric with cotton fire retardant, it can get preferable flame retardant effect.Such as use modified dacron
Fiber Trevira CS and cotton fiber are blended, then to blended fabric flame retardant treatment.But the method cost is higher, product is simultaneously few
See.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found a kind of novel colored fire-retardant wash
Cotton fabric and preparation method thereof makes it with more the utility value in industry.
Invention content
In order to solve the above technical problems, the object of the present invention is to provide a kind of coloured flame-retardant polyester-cotton fabric and its preparation sides
Method, coloured flame-retardant polyester-cotton fabric of the invention be based on it is biomass modified, raw material environmental protection is easy to get, good flame retardation effect, can promote fabric
Physical mechanical property is convenient for industrialized production.
The preparation method of a kind of coloured flame-retardant polyester-cotton fabric of the present invention, which is characterized in that include the following steps：
(1) polyester-cotton fabric is impregnated at 35-40 DEG C in aqueous dopamine solution, then takes out polyester-cotton fabric, washing is simultaneously
Drying, obtains coloured polyester-cotton fabric；
(2) the coloured polyester-cotton fabric that step (1) obtains is impregnated in the phytic acid sodium water solution that pH value is 2~3, elution is simultaneously
Drying；Then the coloured polyester-cotton fabric after drying is impregnated in the chitosan aqueous solution that pH value is 5~5.5, elutes and dries；
(3) step (2) treated coloured polyester-cotton fabric is alternately soaked in phytic acid sodium water solution and chitosan aqueous solution
Stain 15-20 times, and coloured polyester-cotton fabric is eluted after impregnating every time, is dried, obtain coloured flame-retardant polyester-cotton fabric.
Further, in step (1), the fiber quality ratio of polyester-cotton fabric is to wash 10%~80%, cotton 20%~
90%.
Further, in step (1), a concentration of 1.5-2.5g/L of aqueous dopamine solution.
Further, in step (1), polyester-cotton fabric is impregnated 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 chitosan 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), when alternating impregnating, 5-8min is impregnated every time.
The coloured flame-retardant polyester-cotton fabric prepared using the above method is claimed simultaneously in the present invention.
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 washing component and the respective physicochemical properties of cotton component in polyester cotton not
Same, fine structure difference, so two kinds of components and the reactivity of fire retardant differ greatly.The present invention is using extremely strong more of adhesiveness
Bar amine carries out surface modification to it, is equivalent in the polyester-cotton fabric surface construction platform of secondary response.Polyester-cotton fabric surface by
Difference can be presented under certain pH value condition containing abundant hydroxyl and amino in poly-dopamine made of dopamine autohemagglutination
Charge property.In the present invention, in the phytic acid sodium water solution that pH is 2-3, polyester-cotton fabric carries positive charge, and with negative electrical charge
Phytic acid radical ion generate electrostatic interaction, further pH be 5-5.5 chitosan aqueous solution in, surface be negative electrical charge phytic acid
With the chitosan with positive charge Electrostatic Absorption, which occurs, for root in turn so alternately makes the additive amount of fire retardant reach certain
Value, to generate corresponding target flame retardant effect.
According to the above aspect of the present invention, the present invention has at least the following advantages：
The raw material of the present invention is biological material, and dopamine, sodium phytate, chitosan are environmental protection material, thereby, it is ensured that
The safety of the chemicals of the invention used and raw material environment friendly, operation are easy to carry out, and low energy consumption；Made of the present invention
The strength of polyester-cotton fabric is unaffected, and the strength than untreated polyester-cotton fabric is promoted instead, this be because phytic acid root with
After the layer assembly of chitosan, polyester-cotton fabric surface produces caused by the assembling coating of stronger electrostatic interaction.
