Description
Technical field
The present invention relates to cloth preparation technical fields, and in particular to a kind of purified cotton cloth and its dyeing.
Background technique
Pure-cotton fabric be using cotton as raw material, through textile technology produce fabric, have moisture absorption, moisturizing, it is heat-resisting, alkaline-resisting,
The features such as hygienic.
Not by bleaching, dyeing and printing process processing, the cotton of the color with natural cotton fiber is known as grey cotton fabric；It
Grew sheet, coarse cloth, fine cloth can be divided into according to the thickness of yarn count, they the characteristics of be: body is thick and solid, cloth cover is smooth, durable, contracting
Water rate is larger；It may be utilized in fabricating fashionable dress, easy dress, underwear and shirt.
Dyeing is an important treatment process of pure-cotton fabric, needs to use various dyestuffs in dyeing, is directly contaminated
Material spectrum is complete, and dyeing is easy, cheap, is that cotton Products dye one of common dyestuff；Currently, using directly contaminating
Expect dyeing to pure-cotton fabric, it is lower that there are dye-uptakes, and the fabric after dyeing has that light fastness is lower.
Summary of the invention
The first of the embodiment of the present invention is designed to provide a kind of purified cotton cloth dyeing, to solve existing pure cotton cloth
The problem of material after cloth cleaning after dye-uptake during direct dyeing is lower and dyeing and solarization using easily fading.
The second of the embodiment of the present invention is designed to provide a kind of purified cotton cloth, the purified cotton cloth sun-proof jail with higher
Degree reduces cloth and easily fades after cleaning and solarization degree.
To achieve the above object, the embodiment of the present invention provides a kind of purified cotton cloth dyeing, which includes such as
Lower step:
(a) purified cotton cloth is impregnated in sodium hydroxide solution；
(b) it is singed to the purified cotton cloth after immersion, desizing, kiering, bleaching and dyeing；
(c) purified cotton cloth after dyeing is placed in tea and is impregnated, clear water rinsing, is dried.
The present invention passes through impregnates the purified cotton cloth after dyeing in tea, passes through the tea polyphenols and mineral in tea
Prime element can be reacted with the additional water soluble group in dyestuff, improve the molecular weight of direct dyes, so improve dyestuff and
The intermolecular Van der Waals force of fabric fibre；It avoids dyestuff in cleaning process from falling off, the phenomenon that fades occurs；In addition, passing through tea polyphenols
The fabric that can make of introducing during solarization, the photooxidation that can reduce dyestuff is decomposed, and the light fastness of cloth is improved.
Further, in the step (a), the pH value of sodium hydroxide solution is not less than 12, and preferably pH is 13.
Further, in the step (a), soaking time 15-20min, preferably soaking time are 20min.Pass through hydrogen
The immersion treatment of sodium oxide molybdena can remove the sundries on purified cotton cloth surface, and by immersion treatment, remain on purified cotton cloth
Sodium hydroxide the heavy ion in subsequent processing solutions can be removed, improve dyeing effect.
The present invention is to singing, desizing, kiering, bleaching and do not do stringent setting, for example, can be the conventional treatment hand of this field
Section.
Further, in the step (b), dyeing includes the following steps:
(1) dyestuff is dissolved in prepare in distilled water and obtains dye liquor, wherein the concentration of dyestuff is 0.5-0.6g/L；
(2) by after bleaching purified cotton cloth and dye liquor be placed in overflow dyeing machine, bath raio 0.4%-0.6%o.w.f；
(3) sodium chloride is added after overflow dyeing machine is warming up to 50-55 DEG C with the speed of 2-3 DEG C/min and makes its concentration 20-
30g/L, and keep the temperature dyeing 25-30min；It is warming up to 96-98 DEG C to heat up speed with the speed of 2-3 DEG C/min again, heat preservation dyeing 30-
40min；Then, overflow dyeing machine cools down, and dyestuff water is discharged when temperature is down to 35-40 DEG C for 1-2 DEG C/min for cooling rate, and
Rinse 10-12min.The present invention can be improved the dye-uptake of dyestuff, made by the control of specific dyeing temperature and time
Cloth even dyeing, dye stability are good.
Further, the dyestuff is direct dyes；Preferably, the direct dyes is selected from direct black EX, directly dark brown
Any one in MM and direct bordeaux B.
Further, in the step (c), tea temperature is 50-60 DEG C；Soaking time is 15-20min.
Further, the tea is prepared by the way that tealeaves is placed in immersion 10-15min in 95-100 DEG C of hot water；Its
In, the mass ratio of tealeaves and hot water is (0.8-1.2): 100.
Further, the tealeaves is oolong tea or Iron Guanyin.
The second aspect of the embodiment of the present invention provides a kind of purified cotton cloth, the purified cotton cloth by by above-mentioned dyeing into
Row dyeing obtains.Purified cotton cloth light fastness with higher of the present invention reduces cloth and easily fades after cleaning and solarization journey
Degree.
The embodiment of the present invention has the advantages that
(1) present invention can be improved dyestuff and the intermolecular bond strength of fabric fibre by specific dyeing；It avoids
Dyestuff falls off in cleaning process, the phenomenon that fades occurs；And the photooxidation that can reduce dyestuff is decomposed, and the sun-proof jail of cloth is improved
Degree.
(2) present invention can be improved the dye-uptake of dyestuff, the cloth made by the control of specific dyeing temperature and time
Expect that even dyeing, dye stability are good.
(3) it is easy after cleaning or solarization to reduce cloth for purified cotton cloth provided by the invention light fastness with higher
Fade degree.
