Description
Technical field
The preparation method that the present invention relates to a kind of bafta, the preparation method particularly relating to a kind of bafta with function of removing formaldehyde.
Background technology
Along with widely using of building material and ornament materials, living environment pollutant increase increasingly, and environment worsens increasingly.Indoor common are pest matter up to thousands of kinds, and wherein formaldehyde with the universality existed, the popularity in source, the hazardness of human body is big, deenergized period the factor such as length become one of the most dangerous polluter.
Formaldehyde is VOC VOEs(VolatileOrganicCompounds) in topmost one, in China's toxic chemical priority acccess control list, be in second.Modern scientific research shows: when indoor formaldehyde content is 0.1mg/m3Time just have abnormal flavour and sense of discomfort；0.5mg/m3In time, can stimulate eyes to cause to shed tears；0.6mg/m3Shi Yinqi throat discomfort or pain；Concentration is high again to cause nausea, vomit, cough, uncomfortable in chest, even emphysema of panting；When air reaches 30mg/m3Time can cause death at once.
There is formaldehyde problem in China's newly-decorated residential households in cities and towns 80% at present; these formaldehyde source are in wood-based plate, furniture, wallpaper and coating; when certain environment; formaldehyde will evaporate from these materials; and Form aldehyde release is slowly; often up to more than 10 years, therefore, the mankind will be chronically among the threat of formaldehyde.The time of the mankind about 90% is spent in indoor, and the quality of IAQ (indoor air quality) directly affects the physical condition of people.Reduce indoor formaldehyde concentration, improve IAQ (indoor air quality), be improve human lives's quality, improve level of human health, reduce disease important channel.Therefore, the development tool of function of removing formaldehyde textile is of great significance.
Summary of the invention
It is an object of the invention to provide a kind of simple bafta preparation method, by providing cotton fabric function of removing formaldehyde, and reduce the content of formaldehyde of indoor.The preparation method that the present invention specifically provides a kind of bafta with function of removing formaldehyde.
The technical solution adopted for the present invention to solve the technical problems is:
The preparation method of a kind of bafta with function of removing formaldehyde, it is characterised in that comprise the following steps:
Step one: bafta is carried out pre-treatment；
Step 2: be modified bafta processing；
Step 3: bafta is carried out function of removing formaldehyde arrangement；
Step 4: bafta is carried out stamp.
Wherein, step a pair bafta carries out pre-treatment and mainly bafta is carried out desizing, bleaching, described desizing is the α-amylase of employing 2 ~ 3g/L, 1 ~ 2g/L Surfactant OP-10,1 ~ 2g/L strong osmotic agent, desizing temperature is 95 DEG C, the desizing time is 30 minutes, and adopts 90 DEG C of hot water wash four roads；Bleaching is to adopt cellulase treatment liquid; bath raio 1:10; described cellulase treatment liquid includes alkaline pectase, neutral cellulase, neutral-alkaline protease and xylanase; the weight ratio of four is 3:2:1:1; at 20 DEG C ~ 60 DEG C temperature; in above-mentioned cellulase treatment liquid, fabric treating 30-40 minute, then with 90 DEG C of hot water wash four roads.
Bafta is modified processing by step 2: be at room temperature soaked 10 ~ 20 minutes in the sodium hydroxide solution of 15 ~ 20wt% by bafta, bath raio is 1:10, then fabric is passed through evenness calender, liquid carrying rate is below 50%, then fabric is put into sodium chloroacetate, sodium hydroxide, in the solution of water and ethanol composition, wherein the concentration of sodium chloroacetate is 15g/L, the concentration of sodium hydroxide is 2g/L, the concentration of ethanol is 3g/L, bath raio 1:10, after fabric adds, solution starts to warm up to 50 ~ 60 DEG C, react 30 minutes, followed by 80 DEG C of hot washes 10 minutes, then cold water washing is to neutral, dry.
Bafta is carried out function of removing formaldehyde arrangement and includes four steps by step 3:
(1) will be equivalent to the procyanidin of the 5-7% of bafta weight and be dissolved in 1-ethyl-3-methyl-imidazolium chloride ionic liquid, the weight ratio forming procyanidin ionic liquid, procyanidin and ionic liquid is 2-10:45-60；
(2) bafta at room temperature pads the sodium hydroxide solution of 2g/L, and two leachings two are rolled, every time dipping 10 minutes, and pick-up is 90%；
(3) being immersed in by bafta in the procyanidin ionic liquid of (1), room temperature, dip time is 30-50 minute, and by evenness calender, pick-up is 80 ~ 90%；
(4) by bafta in drying baker, temperature 80 ~ 100 DEG C, dry 5 ~ 10 minutes, then in baking oven, temperature 140-160 DEG C, dry 30 ~ 60 seconds.
It is adopt circular screen printer that bafta is carried out stamp by step 4, select simple pattern to retouch original text to draw, preparing silk screen, adopt reactive dye printing slurry, printing paste includes the reactive dye being equivalent to bafta weight 2%, and the thickener 30% that sodium alginate and guar gum are constituted, carbamide 4%, reserve salt s1%, sodium bicarbonate 1%, steam temperature 105 ~ 110 DEG C after over print, 10 ~ 20 minutes time.
The invention have the advantages that:
The pretreatment process of bafta adopts cellulase treatment, reduce the use of chemical assistant, particularly in bleaching process, the present inventor have selected alkaline pectase, neutral cellulase, neutral-alkaline protease and xylanase, the weight ratio of four is 3:2:1:1, bleaching effect is clearly, low to the loss of fabric；
Bafta is modified by sodium chloroacetate, improves procyanidin to the absorption of bafta, combination, improves its combination rate；
Use ionic liquid as reaction medium, improve the binding ability of procyanidin and bafta further, be effectively increased its adsorption rate, combination rate and washing fastness；
And inventor finds in actual production, if what bafta was taked after carrying out function of removing formaldehyde arrangement is dyeing, the combination of procyanidin and bafta can be destroyed, if carrying out dyeing or stamp before function of removing formaldehyde arranges, then affect the combination of procyanidin and bafta, have the color adopting printing with reactive dye providing cotton fabric certain only, procyanidin is minimum with the combination of bafta impact, expand the use scope of bafta.
Adopt GB50325 2001(2006 version) detection, formaldehyde clearance reaches more than 90%.
Using the bafta that preparation method of the present invention obtains can directly and contact skin, safety be good, does not have carcinogenic, teratogenesis or causes allergic reaction；Good with the ecological environment compatibility, biodegradable, it is a kind of novel green product, its market prospect is very wide, can be applicable to the field such as home textile, garment material.
