Abstract
The invention relates to an auxiliary agent in the printing and dyeing industry, in particular to a wet rubbing fastness improver for dyed fabric, which is characterized in that the wet rubbing fastness improver is nonionic polymer, of which the main component is polyether compound containing water; the wet rubbing fastness improver is formed by copolymerizing 10 to 30 portions of low-hydro silicone oil, 30 to 60 portions of polyurethane prepolymer and 20 to 40 portions of polypropylene ester copolymer under the conditions of catalyzing and heating; and the portion is weight portion. The wet rubbing fastness improver can improve the wet rubbing fastness of the fabric dyed by direct, active, acid and other dyes by 2 to 3 level to reach above 3 level, has no influence on the tone of the dyed fabric basically, does not influence the light fastness and chlorine fastness, and improves the perspiration-light fastness.
Description
Technical field
The present invention relates to the dyeing auxiliary agent, relate in particular to DYED FABRICS crock fastness elevator.
Background technology
For a long time, the fastness to wet rubbing of water-soluble dyes such as direct dyes, REACTIVE DYES, ACID DYES can not satisfy customer requirement and be paid close attention to by people always, (more than the 7%o.w.f) was particularly outstanding when especially cellulose fiber Wesy REACTIVE DYES was dyed dark heavy colour, because the REACTIVE DYES amount of set is not quite a lot of with fiber generation covalent bond.Carry out fixation though dye the back with color-fixing agent, fastness to wet rubbing can access improvement to a certain degree, and often good, the fastness to wet rubbing of colour fixation promotes high color-fixing agent to the having the greatest impact of the coloured light that dyes thing, and fastness to wet rubbing seldom can reach 3 grades.
Along with the client is more and more higher to the requirement of the fastness to wet rubbing of lining, it is very necessary that the various factors that influences the DYED FABRICS fastness to wet rubbing is discussed.Conclusion is got up, and mainly contains the following aspects:
The kind of fabric and institutional framework
In general, the chemical fibre DYED FABRICS is better than the fastness to wet rubbing of natural fabrics such as cotton, and knitted fabric is better than woven fabric, and frivolous loose fabric is better than thick and heavy fabric closely.Fabric such as sanding cloth, corduroy is because fiber surface area is big, and the dyestuff that contacts during friction is more, so fastness to wet rubbing is relatively poor.
The pre-treatment of fabric
Fabric pretreatment such as destarch, kiering, bleaching, mercerising and HEAT SETTING etc. will be spared saturating, with the accessibility that improves fiber and with the reactivity or the physical absorption anchorage of dyestuff, make dyestuff dye, be penetrated into fibrous inside and set on fully, prevent that the fiber surface dyestuff from too much causing padding or ring to dye, fastness to wet rubbing is descended.
Dyeing
The selection of dyestuff: every fastness of some dyestuff comprises that fastness to wet rubbing is better, the fastness of some dyestuff is then relatively poor, as the fastness to wet rubbing extreme difference of direct dyes, sulphur black, active dark blue deeply, reactive scarlet etc., and fastness to wet rubbings such as DISPERSE DYES and the luxuriant sub-dyestuff of sun are better; Dyeing concentration: middle light fabric fastness is better, and dark heavy colour (more than the 7%owf) fastness is relatively poor.Dyeing: the control of temperature, time wants strict, if temperature, time are not enough, causes dyestuff not dye and infiltration and set on fully, and the dyestuff of set is not too much to make fiber surface, causes fastness to wet rubbing to descend.Also have the selection of auxiliary agent to use with correct; In addition, the fastness to wet rubbing of deep printing cloth is also relatively poor.
The DYED FABRICS post processing
Dying thing fully soaps and can improve fastness to wet rubbing; Terylene with disperse dyeing after high-temperature shaping can cause the dye migration bleeding to PET fiber surface, cause fastness to wet rubbing to descend; Fixation treatment by form the color lake, crosslinked and film forming can to a certain degree improve the fastness to wet rubbing that dyes thing; With smooth agent fabric is carried out smooth, soft and handle, make fiber surface level and smooth, resistance and coefficient of friction also can improve the fastness to wet rubbing that dyes thing to a certain extent when reducing friction; Above post-processing approach can only make the fastness to wet rubbing of fabric improve to a certain extent, does not deal with problems at all.
Summary of the invention
The objective of the invention is to overcome the existing defective of improving fabric fastness to wet rubbing means, a kind of wet friction fastness improving agent for dyeing fabric is provided.The fastness to wet rubbing that dyes thing of dyestuffs such as wet friction fastness improving agent of the present invention can make directly, activity, acidity improves the 2-3 level, reaches more than 3 grades, and the coloured light that dyes thing is not had influence substantially.Light fastness, chlorine fastness are not influenced, the sweat fastness to light is increased.
The present invention is achieved in that
