Description
Technical field
The present invention relates to a kind of textile auxiliary and preparation method thereof and use technique, more particularly, to a kind of textile dyeing thing
Dry fastness elevator preparation technology and dry fastness lifting process.
Background technology
Can the color fastness of textile dyeing thing up to standard, related to many factors, except dye type used and dyeing
Mutually outside the Pass, the organizational structure with fabric, configuration of surface also has much relations.In numerous color fastness indexs, textile friction
Fastness is one of current more scabrous problem, and in traditional product dyed thereby postfinishing process, with fixing agent y, color fixing agent m etc. is carried out
Fixation treatment, to improving the color fastness of product dyed thereby, including crock fastness, but due to fixing agent y, color fixing agent m etc. contains
Formaldehyde is harmful, has completely forbidden use at present.
In recent years, domestic and international printing and dyeing assistant industry develops cationic poly quaternary ammonium salt color fixing agent, polyurethaness in succession
Color fixing agent etc., the wet fastness lifting to textile dyeing thing serves positive effect, especially product dyed thereby fastness to wet rubbing；For a long time
Since limited by the technology barriers of Export Textiles, be difficult to up to standard.Above type of product dyed thereby color fixing agent is to some specific
Textile, such as Pilus Caprae seu Oviss coarse woolen fabric, woven fabric fabric, the dry fastness of a pile fabrics, not only fail to improve, have decline on the contrary
Trend.In addition, the problems such as cation type color fixing agent can cause product dyed thereby changes of shade unavoidably, and feel is stiff.Therefore, grind
Textile dyeing thing dry fastness elevator processed is imperative, is but a technical barrier of industry all the time.
The principal element of impact textile dyeing thing dry fastness has: (1) textile dyeing thing organizational structure and surface shape
State, such as slubbing kind fabric, such fabric face is coarse, and the coefficient of kinetic friction is big, shows crock fastness not good.(2) with product dyed thereby table
Face dyestuff accumulating amount is relevant, and that is, deep-colour fabric performance crock fastness is poor, this differences in concentration gradient with dyestuff in fricting movement
Relevant.(3) relevant with dye structure, such as phthalocyanines dye, penetrate into fiber lumens because molecule is more difficult greatly, be easily piled up in fiber
Surface, affects its crock fastness.
Content of the invention
The technical problem to be solved is to provide for one kind and can effectively improve textile dyeing thing dry fastness
Elevator and this elevator preparation method, simultaneously provide using this dry fastness elevator lifted textile dyeing thing
The technique of dry fastness.
For solving above-mentioned technical problem, technical scheme is as follows:
A kind of textile dyeing thing dry fastness elevator, this elevator is the mixed aid comprising following component:
Sulfobetaine type amphoteric surfactant, its chemical formula is rn+(ch3)2(ch2)so- 3, wherein r=c16h33；
Cross-linking epoxide group condensation substance, described cross-linking epoxide group condensation substance is diamidogen and epoxychloropropane
Condensation substance；
Polyethylene emulsion；
Diethylene glycol.
Further, the weight portion of described each component is as follows:
Simultaneously the invention provides the preparation method of above-mentioned textile dyeing thing dry fastness elevator:
A, first preparation sulfobetaine type amphoteric surfactant；
Intensification stirring and dissolving in b, input reactor；80-90 DEG C of water-bath, stirs to no granule, is in milky white thin paste,
Be cooled to 40-50 DEG C standby；
C, dissolving, in the sulfobetaine type amphoteric surfactant paste that cools down, sequentially add diethylene glycol, poly-
Vac emulsion, cross-linking epoxide group condensation substance, add while stirring, after mix homogeneously, filtering and discharging.
Present invention also offers a kind of padding process using above-mentioned textile dyeing thing dry fastness elevator, step
As follows:
A, preparation dry fastness elevator, according to product dyed thereby depth of color and textile surface form, the preparation that adds water is dense
Spend and pad treatment fluid in padding in groove for 30-50g/l；
The padding process that b, textile roll through two leachings two, pick-up rate keeps 70-100%；
C, prebake, then bake, and complete to pad process.
Wherein, preferably bake 1-2min at 130 DEG C after prebake.
Present invention also offers a kind of impregnation technology using above-mentioned textile dyeing thing dry fastness elevator, step
As follows:
A, preparation dry fastness elevator, with product dyed thereby depth of color and textile surface form, by pending weaving
The 3-5% of product weight prepares dry fastness elevator consumption；
B, add water configuration impregnation process liquid, using bath raio 1:10-20, under room temperature by textile add impregnation process liquid in,
It is warming up to 50-60 DEG C of impregnation process；
C, taking-up textile are dried, and then bake, complete impregnation process.
The wherein said time being warming up to 50-60 DEG C of impregnation process can be 30min.
The present invention is that passed through to obtain in long-term research and development and practice summary a kind of unique can effectively improve weaving
The elevator of product product dyed thereby dry fastness, provides preparation method and the handling process of this elevator simultaneously, has filled up and knitted
The blank of effective dry fastness lifting process in thing postfinishing process.
The enhancement mechanism of the dry fastness elevator of the present invention: (1) select sulfobetaine type amphoteric surfactant,
Under the conditions of different ph, all it is provided that the group being available for crosslinking；Under the conditions of meta-acid, its positive charge can be shown, in meta-alkali bar
Under part, its negative charge can be shown, both can with mixed aid in there are reactive epoxy groups play crosslinked action, again can be with dyestuff
The Electrostatic Absorption such as upper anionic group or hydroxyl, amino, forms color lake deposition, and its extensive crosslinked action in some sense may be used
Say it is to play effective bridging action.(2) select cross-linking epoxide group condensation substance: as the condensation of diamidogen and epoxychloropropane
Thing, under certain action condition, sulfonic group in epoxy ring-opening, with mixed aid, the crosslinking such as carboxyl, hydroxyl in dyestuff,
Fiber surface forms network structure thin film, and dye for fabrics is formed with the reticular protection film being effectively implicative of each other.(3) select poly- second
Alkene emulsion, its own is hydrophobic high molecular polymer, after the drying can film forming, and because flexible macromolecular chain has soft work(
Can, along with that selects has under the diethylene glycol collective effect of lubricating function, reduce the dynamic friction on textile dyeing thing surface
The key factor of this impact dry fastness of coefficient, slow down the textile dyeing thing surface dye causing because of dry friction
Migration.
Dry fastness elevator using the present invention can lift dry fastness effectively, can averagely lift product dyed thereby
Dry fastness 1-2 level.It is applied to Pilus Caprae seu Oviss coarse woolen fabric, woven fabric fabric, plays pile fabrics etc., many experiments show for failing
The pending textile of up to standard some, former dry fastness is only 1-2 level, and the dry fastness elevator through the present invention is processed
Afterwards, up to 3-4 level, the standard that reaches requires dry fastness.The elevator that the present invention provides and technique greatly reduce dyeing and finishing work
Percent defective in skill, the substantial amounts of lattice fabric that do not conform to is improved as qualified products, agrees with the industrial development theory of energy-saving and emission-reduction.
Product dyed thereby coloured light does not change: dry fastness elevator of the present invention no affects on product dyed thereby coloured light, general cation
Class color fixing agent more or less makes product dyed thereby coloured light partially wither secretly；Or inclined HONGGUANG or inclined blue light.
Product dyed thereby is soft: dry fastness elevator of the present invention, for ordinary stain thing, can save follow-up
Soft finish, saves operation.
