Abstract
The invention provides a shrinkproof finishing method for wool fabric, which comprises the following steps: A)preparing fabric; B)preparing a finishing liquid, adding 0.5-1.5% owf degraded chitosan, 3-6% owf cross-linking agent citric acid and 1-4% owf catalyst sodium hypophosphate in a roll groove; C)performing fabric oxidation pretreatment by using 15-20g/L of hydrogen peroxide and 2g/L of stabilizing agent for 1 hour under temperature of 70 DEG C, wherein pH value is 9; D) dipping and padding twice, wherein the mangle expression is 85%, employing ultrasonic treatment during a padding process at the padding temperature of 45-65 DEG C; E)drying; F)washing; and G)drying. The shrinkproof finishing method employs the ultrasonic treatment during the padding process and increases the grafting rate of chitosan on wool fiber, ultrasonic treatment enables brightening of the wool scale, so that friction effect of wool is reduced, and the felting performance of lambswool is reduced; through synergism, the finished wool fabric has excellent shrinkproof performance and fluffiness.
Description
Technical field
The present invention relates to a kind of finishing technique of fabric, especially relate to a kind of shiinkproof finish method of wool fabric.
Background technology
Wool has advantages of many as a kind of natural protein fibre, such as warmth retention property is good, good springiness, quality is strong and have certain anti-flammability and soil resistance, makes it deeply be subject to consumers in general's favor.Wool fibre is a kind ofly by people, to be used maximum animal fibers in addition, has good moisture absorbing, is described as " animal fiber that can breathe ", cool in summer and warm in winter. the four seasons all can be used.The scale structure of wool surfaces is a main feature of wool fibre, and this structure can cause the incorgruous friction effect of fiber, thereby makes wool fibre have feltability.Although its feltability can make wool textile have individual style, such as can reach high resilience after appropriate fulling milling arranges, plentiful abundant effect, but feltability is unfavorable for the wearability of textiles, can make fiber produce felting clayization phenomenon when washing.Fabric thickening. wiriness, the size of clothes is unstable etc.
The essence of shiinkproof finish is the form that changes wool surface scale, and restriction wool occurs mutually to tangle.Mainly to utilize chemicals and scale to have an effect, damage and softening scale; Or utilize resin to be diffused in uniformly fiber surface, and form film, thereby effectively limited the effect of scale, make wool fibre lose feltability, reach shrinkproof object.
Summary of the invention
A kind of shiinkproof finish method that the object of this invention is to provide wool fabric.
The present invention will solve is the defects such as the finishing effect that exists of the shiinkproof finish method of existing wool fabric is not ideal enough.
Technical scheme of the present invention is: a kind of shiinkproof finish method of wool fabric, and described method at least comprises the steps: the preparation of a. fabric: wool fabric, with after 40 ℃ of warm water cleanings, is dried to constant weight; B. dressing liquid preparation: add shitosan, 3～6% owf crosslinking agent citric acids and 1～4% owf catalyst inferior sodium phosphate after 0.5～1.5% owf degraded in groove, be mixed with solution; C. fabric oxidation pre-treatment: by the hydrogen peroxide of 15～20g/L, the stabilizing agent of 2g/L for wool fabric, at pH=9, process 1 hour at 70 ℃; D. pad: the wool fabric after oxidation processes is put in dressing liquid and padded, and described padding finishing operation adopts two to soak two and roll, and pick-up rate is 85%, described in the process of padding adopt ultrasonic wave to process, described in to pad temperature be 45～65 ℃; E. dry: the wool fabric after padding is dried 3～5 minutes at 70～80 ℃; Wool fabric after drying is baked to 1～3 minute at 120～140 ℃; F. washing; G. dry: the wool fabric after washing is dried 3～5 minutes at 70～80 ℃.
The biodegrading process of described shitosan is: shitosan is joined in the glacial acetic acid solution that concentration is 5wt% by a certain percentage, after dissolving completely, adding concentration is that the hydrogen peroxide of 30wt% is as oxidant, control reaction temperature and reaction time, after reaction terminating, adding sodium hydrate regulator solution pH value is 7, make shitosan Precipitation, the shitosan after being degraded after filtering, wash, being dried.
In described ultrasonic wave processing procedure, the ultrasonic frequency of selecting is 35～45KHz.
The beneficial effect that the present invention produces is: compared with prior art, shiinkproof finish method provided by the invention, padding in process adopts ultrasonic wave to process, not only can improve the percent grafting of shitosan on wool fibre, and ultrasonic wave itself also can make wool scale rust, become light, thereby reduce the friction effect of wool, reduce the felting performance of wool; After both synergies, can make the wool fabric after arranging there is very excellent shrinkproof performance and bulkiness.
The specific embodiment
Below in conjunction with embodiment, the invention will be further described.
A shiinkproof finish method for wool fabric, described method at least comprises the steps: the preparation of a. fabric: wool fabric, with after 40 ℃ of warm water cleanings, is dried to constant weight; B. dressing liquid preparation: add shitosan, 5% owf crosslinking agent citric acid and 2% owf catalyst inferior sodium phosphate after 1.5% owf degraded in groove, be mixed with solution; C. fabric oxidation pre-treatment: by wool fabric with the hydrogen peroxide of 18g/L, the stabilizing agent of 2g/L, at pH=9, process 1 hour at 70 ℃; D. pad: the wool fabric after oxidation processes is put in dressing liquid and padded, and described padding finishing operation adopts two to soak two and roll, and pick-up rate is 85%, described in to pad process proportion be that the ultrasonic wave of 35～45KHz is processed, described in to pad temperature be 55 ℃; E. dry: the wool fabric after padding is dried 3 minutes at 80 ℃; Wool fabric after drying is baked to 2 minutes at 130 ℃; F. washing; G. dry: the wool fabric after washing is dried 3 minutes at 80 ℃.The biodegrading process of described shitosan is: shitosan is joined in the glacial acetic acid solution that concentration is 5wt% by a certain percentage, after dissolving completely, adding concentration is that the hydrogen peroxide of 30wt% is as oxidant, control reaction temperature and reaction time, after reaction terminating, adding sodium hydrate regulator solution pH value is 7, make shitosan Precipitation, the shitosan after being degraded after filtering, wash, being dried.
In the process of padding, adopt ultrasonic wave to process, can wool fibre is expanded, and be conducive to the scale layer of wool surface to be opened, make crosslinking agent be more prone to wool fibre on amino react, improved the percent grafting of shitosan on wool fabric surface.In addition, ultrasonic wave is processed can make wool scale rust, become light, thereby reduces the friction effect of wool, reduce the felting performance of wool, and action time is longer. and reduction degree is larger.Therefore, ultrasonic wave not only can promote chitosan crosslinked on wool fibre, makes shitosan in wool surface film forming; And itself also can reduce the felting performance of wool.
