Abstract
The invention relates to a method of modifying the surface of a fabric which comprises the successive steps of: i) exposing the fabric surface to UV radiation; and ii) oxidative treatment of the fabric.
Description
The present invention relates to the processing of wool and wool-blend fabric, relate in particular to the fabric treating new method that can when printing and dyeing, obtain good tinctorial yield and/or can reduce balling-up.
For many years, wool and wool-blend fabric can improve and/or strengthen numerous characteristics through processing with after handling.For example, the preliminary treatment to fabric such as wool is the key factor that obtains good tinctorial yield, level-dyeing property and brightness before the printing and dyeing.Similarly, people had once proposed many method of processing and treatment, to reduce or eliminate balling-up.
Traditionally, chlorination once was used, and several subforms of chloridization process are still being used, and almost only was ready to wool fabric for printing and dyeing.DCCA (DCCA) is the chlorinating agent that the most generally uses at present, and can be by intermittently (the most frequently used) and continuous processing are used.Batch process comprises with the DCCA that accounts for fiber quality (omf) 3-4% and to carry out the dechlorination post processing with sodium hydrogensulfite and acetate subsequently about 1 hour of PH3.5-4.5 and 20-40 ℃ of following chlorinations of temperature.Continuity method comprises pad dyeing DCCA (35-50gl
-1), before rinsing, stopping 2-5 minutes subsequently, the dechlorination that then is similar to batch process is handled.What replace DCCA is the Kroy chlorination, quotes at first and handles wool tops, and it uses the solution of chlorine in water in continuous fabric treating technology.Chlorine and water reaction obtain the mixture of hypochlorous acid and hydrochloric acid, and it is sprayed directly on on the fabric with wetting agent.This reaction is faster than DCCA, and still, rinsing and dechlorination are handled to be still to be needed.Process velocity 10-15mmin under 4%omf chlorine dosage speed
-1Be typical, and fabric is obtained and the similar performance that is obtained with the 4%DCCA processing.
The typical problem of fabric chloridized comprises: yellowing, and even depth effect (even ap-plication), fiber is impaired.The same fabric (usually using hydrogen peroxide) that often needs bleaching chlorine to handle is to remove yellow before printing and dyeing.Yet the technology that relates to chlorine exists the pressure of environment aspect, and when especially having absorbable organic halogen (AOX) in plant effluent, this will certainly cause replacing chloridization process with substitute technology.
Other method that is used for handling fabric before printing and dyeing is uncommon.Two kinds of polymer treatment approach, a kind of to wool tops and a kind of be at present known to fabric, they are:
1.Hercosett 125 (trade names)
, after the stage this polymer is applied on the wool tops at prechlorination.The fabric that makes from treated wool tops strengthens the affinity of anionic dye.Other machining that takes place in grilling, spinning and weaving process can obtain level dyeing goods (level prepara-tion).Yet tinctorial yield trends towards step-down, because the chlorine that uses is few.In addition, also must carefully wash, because the wool of handling has very high affinity to loose anionic dye.
2.Synthappret BAP (trade name)
This polymer can be applied on the fabric, and need not the prechlorination step.With this polymer treatment fabric, make fabric have very high affinity before the printing and dyeing to hydrophobic dye.Yet, having reduced the penetrability that printing paste enters fiber without chlorinating step, the control under the decatize condition is very harsh.This method once was used for the wool/cotton blended fabric of printing and dyeing, but was not used for pure wool fabric so far.
Now developed other method of avoiding using chlorine, can't think to have commercial viability, although they have reduced the pressure to environment.Summary is got up, and commercial being widely used for comprises for only art methods of printing and dyeing preliminary treatment wool fabric: chlorination, and rinsing and dechlorination are handled, however these methods may need bleaching to handle to remove yellow.
" balling-up " is the term that is used for being described in the less fibre ball closely of formation on the fabric face.Balling-up is very big to the clothes infringement, causes shabby and disheveled outward appearance, especially knitwear more is a problem.
The balling-up process is complicated, but can describe by four successive stages:
(i) form fine hair.The slight rubbing action that takes place in the wearing process is some surface fibers of pull-up from female yarn, cause the fine hair surface.
(ii) fine hair tangles.Higher cashmere density appears in the zone of the more frequent friction of experience on the clothes.Fiber in this zone tangled in certain stage, formed loose ball.
(iii) ball forms and growth.Continuous friction in loose entanglement place makes some loose points that tangle be rolled into ball more closely.These tight balls are resisted other frictional force, some more weak fibrous fractures in the ball.Stronger fiber is kept perfectly and ball is fixed on fabric face.Along with constantly batching loose fiber from fabric face, ball is grown gradually.
(iv) ball comes off.Anchoring fiber is finally yielded to the power that acts on the steady growth on the ball, suffers fatigue rupture.When each anchoring fiber fracture, those fibers that remain are forced to bear bigger power, thereby have quickened the speed that anchoring fiber destroys.When the speed of anchoring fiber fracture surpassed the speed of ball growth, ball dropped.
The character of fiber (source, processing history, physical size), yarn (type is twined) and fabric construction are whole key factors of balling-up.When dressing, exist other variable factor to influence balling-up speed.As everyone knows, some wearers produce faster and wider pilling effect than other people.Washing changes balling-up character basically.How horrible also be present in the balling-up of specified rate be to subjective difference between the individual.
Known have several chemical treatment methods to be used for reducing balling-up, although also there is not any method can guarantee not balling-up when dressing.For example, be commonly used to shrinkproof oxidation chlorination method and obtained some good results.Chlorination/Hercosett and some other polymer treatment (they suppress the fiber migration by forming inter-fibre-bond) also are very useful.More destructive dyeing condition (promptly length is boiled the time of boiling high temperature, PH extremum) also trends towards reducing balling-up.
Similar with the printing and dyeing preliminary treatment, at present for for the technology of chlorine, exist a large amount of environmental pressures, especially when in factory's discharge liquor, producing absorbable organic halogen (AOX).Thereby, from now in a decade or so in, the effectively anti-balling-up of the part that may will stop using involve chlorine compound is handled and the printing and dyeing preliminary treatment.
The applicant now is surprised to find, and allows fabric pass through UV radiation oxidation bleaching subsequently, and the combination of these two kinds of technologies has obtained a kind of cooperation mechanism, can effectively improve the possibility that fabric obtains the ability of good tinctorial yield and reduces balling-up when printing and dyeing.
Use separately the broad research of UV radiation or oxidation bleaching to confirm, one step improve tinctorial yield or significantly reduce aspect the balling-up invalid.Confirm that also the oxidation bleaching step must be after radiation, and can not at first adopt, or adopts under the situation that can not wet in radiative process.Also find, in the middle of the dye type within the specific limits, adopt two step operating process to obtain high and uniform tinctorial yield, better than the tinctorial yield that produces by 4%DCCA.
To the research of the great majority of the influence of wool, its target is to limit long-term negatively influencing about UV, as dyes the photic yellowing, photic tendering and fade of the wool of look.
(previous research work of the positive application facet of λ＜400nm) seems to be limited on two pieces of patents that industrial value arranged about UV radiation in the processing of wool fabric.
U.K. patent 811702 is described the use of ultra-violet radiation aspect the dyestuff absorptivity of improving wool fabric.This mode has improved the tinctorial yield of (under radiation) exposure fabric, depends on the character of used dyestuff.Use suitable engraved plate in the radiative process, in dyeing course, use dye resisting agent subsequently, can produce camaieu effect like this partly to protect the not radiation areas of fabric.This file also discloses, and in order to shorten radiated time, is preferably in and uses the oxidizer treatment fabric in the UV process-exposed.Yet this file does not have to describe or advises the possibility of radiation application in fabric printing, or in fabric oxidation bleaching method to fabric after overshoot.In fact, the U.K. patent has emphasized to use in UV irradiation process oxidant with the shortening radiated time, rather than improves the affinity of fabric to dyestuff as the independent process of necessity in the collaborative technical process.
Japan Patent H4-41768 claims that independent UV irradiation is effective Antishrinking method of wool fabric.Yet, in our research, do not reproduce the fabric area that significantly reduces that (they) claimed and shrink.This may be owing to the character of the used wool fabric of Japanese worker, or because the operation of their fulling milling does not have our such strictness.
Especially, the invention provides the method on a kind of modified fabric surface, it comprises following continuous step:
(i) fabric face is exposed under the UV radiation; With
(ii) to the oxidation processes of fabric.
In the first step of the inventive method, fabric can carry out radiation by the ultraviolet light from any suitable sources.Preferably in preferred 400-180nm scope, fabric is carried out ultra-violet radiation.More preferably fabric carries out the short wavelength UV radiation that wavelength is 280-200nm (UV-C) more preferably has near the wavelength (approximately 254nm) the obtained the maximum absorption of disulfide bond in wool.
Ultra-violet radiation can be provided by any suitable light source.The selection of light source will be depended on the intensity and the wavelength of the radiation that is used for this method.That the preferred source of radiation of ultra-violet radiation comprises is low, in and high-pressure mercury arc lamp, and xenon discharge tube.In a preferred embodiment of the invention, can use the low pressure mercury arc of the emission UV of generation 85% under 254nm.
