Description
Technical field
The invention belongs to Cotton Fabric field, more particularly to a kind of bafta durability reacted based on ultraviolet light polymerization
Flame-retardant finishing method.
Background technology
The advantages of cotton Products are because of its flexible, breathable, absorption comfortable and function admirable, is widely used in clothes, decoration
Material and other field, but cotton fiber easily burns, and the limited oxygen index of natural cotton fiber is 18 or so, in order to reduce burning danger
The release of toxic gas, reduces people's life and property loss during dangerous and burning, carries out flame-proof treatment to bafta and seems particularly
It is important.
At present existing flame-retardant finishing method substantially has following several：
One is dipping flame-proof treatment.Will fire retardant be made into certain density mixed solution, solvent be water, organic solvent or
Emulsion form.Fabric impregnates in solution at a certain temperature and reaches after certain adsorbance, carries out squezzing and drying, general baking temperature
Less than 100 DEG C.Insoluble sex flame retardant can be deposited between cellulose fibre using infusion process, in physically adsorbing.Simple leaching
The method of stain is simple to operate, and using conveniently, general cost is relatively low, but method presence generation waste liquid is more, and can cause certain dirt
Dye, the defect such as finishing effect is durable or semi-durable.
Two be pad-bake flame-proof treatment.In soaking the fabric into the fire-retardant body lotion for padding plant equipment, continuously pad to
Then the pick-up of fabric is dried and bakes up to certain requirement, makes fire retardant and cellulose react, or by preshrunk
Thing is crosslinked in fabric.The temperature for baking depends on flame retardant performance, unreacted medicament on washout fabric after baking, dry
Finished product.This is the most widely used method of current flame-proof treatment, it is adaptable to the fabric fire-retardant finishing of cellulose fibre, and fiber is damaged
Wound is little, and the quality for processing fabric is high, processes colourity, pH value, the COD value of waste water far below traditional handicraft, alleviates sewage disposal
Burden, be conducive to ecological environmental protection, also with production efficiency height, low labour intensity, energy-conservation, water saving the features such as.But also deposit
In shortcoming, such as flame retardant effect is not durable, and high temperature to bake that easily make fabric yellowing, feel stiff.
Three is coating flame-proof treatment.Usually fire retardant is mixed in resin and is processed.According to the difference of plant equipment
Divide scraper for coating method, casting rubbing method and calendering rubbing method.The method process is simple, and dosing is few, and three wastes discharge amount is few, but
Usual only surface flame-retardant, sometimes up to less than high flame-retardancy requirements.This method is adopted the flame-proof treatment of carpet backing thing more.

Fast even suspension in the liquid phase, the densification of pm level thickness is formed by method physically or chemically with suitable capsule material on its surface
Cyst wall, the high moderate pressure of the necessary resistance to Polymer Processing of cyst wall, and chemical reaction can not occur with the fire retardant of parcel, work as product
When fire is met by hyperpyrexia, cyst wall can melt fracture immediately, so as to discharge fire retardant, reach fire-retardant purpose.Microencapsulation hinders
The advantage that combustion is arranged：Air-liquid state fire retardant can be made to become solid-state fire retardant Jing after microencapsulation, existed so as to reduce liquid flame retardant
Migration inside polymeric material and cause the loss of fire retardant in polymeric material due to the volatilization of liquid；Fire retardant bag
The compatibility increased after suitable capsule material with polymer is wrapped up in, fire retardant is reduced and eliminate to polymer product physical and mechanical property
Adverse effect；The physical properties such as density, the volume of fire retardant can be changed.But, microencapsulation flame-proof treatment there is also necessarily
Shortcoming：The selection and design of core material and shell material is more bothered；The control of wall thickness is more difficult；Some existing microcapsules
Flame retardant products quality needs further to improve；Preparation cost is higher, and clad ratio is not high, and application is restricted.
Five is hydroxyl covalent bond flame-proof treatment.Can produce during the reactive flame retardant use of early stage free formaldehyde and
Release formaldehyde problem, the formaldehyde not combined with amino in the initial reduced body penetrant arranging bath that free formaldehyde is mainly in resinamines, or
The raw material for being synthesis fire retardant is formaldehyde；Release formaldehyde is the fabric of Jing N- methylol compounds arrangement under certain damp condition
Decomposite the formaldehyde for coming.Therefore environmental issue is more focused in the evolution of reactive flame retardant.Hydroxyl covalent bond hinders
Combustion is arranged and most significant advantage is that its finishing effect is water-fastness, and durability is strong, but from from the aspect of cost and large-scale application,
Also exist and limit and certain development space.
In recent years, it is increasingly deep with correlative study, people gradually recognize the mechanical performance of flame-proof treatment damage, first
Aldehyde harmfulness and environmental persistence, therefore, finding environmental protection, efficiently durable flame-retardant finishing method becomes relevant industries
Study hotspot.Click chemistry with its reaction condition it is gentle, yield is high, speed is fast, product can be easily separated and high selectivity etc.
Advantage, becomes one of focus of domestic and international research.Mercaptan-alkene chemical reaction is enjoyed in recent years as new and effective click-reaction
Concern.At present the development of click chemistry is extremely rapid, has been related to every field, particularly functional polymer, surface modification,
The aspects such as large biological molecule, DNAs, biological and chemical sensor achieve the achievement attracted attention.But will click on chemistry and apply to weaving
Research on product finishing functions is less, and existing related research shows, bafta is carried out using silane coupler it is sulfhydryl modified,
And by the excellent water repellency of ultraviolet light polymerization providing cotton fabric；Sulfydryl reduction is carried out to wool using TCEP, and by purple
Outer photocuring gives wool excellent anti-microbial property.Therefore, as attempted will click on chemistry in combination with bafta flame-proof treatment, lead to
Sulfydryl-alkene clicking chemistry principle is crossed, bafta can just be chemically bonded with fire retardant, obtain durable fire resistance.
