Abstract
The present invention relates to a kind of methods for adjusting fabric bleaching pH value using citric acid.Characterized by the following steps: fabric is washed in alkaline solution；The fabric washed in alkaline solution is taken out, dehydration, then is washed with water；It is taken out described again with the fabric that water washs, dehydration, then the dewatered fabric is soaked in water, the pH value that citric acid adjusts the fabric is added in the water；Be added in water citric acid adjust continuously add after the pH value of the fabric alkyl phenol polyoxyethylene ether fabric is carried out it is soft；Fabric carries out soft fabric and takes out, and is formed after dehydration, and the setting temperature is 170-180 DEG C.It is compared with the traditional technology, the method that present invention application citric acid adjusts fabric bleaching pH value increases the technique for adjusting the pH value of fabric, and the pH value of fabric is controlled in target range, the xanthochromia degree of fabric in the subsequent process is reduced.
Description
Technical field
The present invention relates to a kind of methods for adjusting fabric bleaching pH value using citric acid.
Background technique
The garment print of white goods will bake by the high temperature of 160 degrees centigrades in printing technology, can make in this way
White goods generates biggish xanthochromia, influences color, is not able to satisfy the requirement of client.For the xanthochromia of white goods garment piece stamp
It is required that higher, front cut pieces, rear garment piece, left sleeve and right sleeve, by the different numbers that bakes, do not reduce drift due to the difference of the flower pattern of print
The xanthochromia of white textile printing meets after these garment piece stamps system that will generate apparent color difference to dress again.
Summary of the invention
Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a kind of application citric acids to adjust fabric drift
The technical solution of the method for white pH value.
A kind of method adjusting fabric bleaching pH value using citric acid, it is characterised in that the following steps are included: will
Fabric is washed in alkaline solution；The fabric washed in alkaline solution is taken out, dehydration, then is carried out with water
Washing；It is taken out described again with the fabric that water washs, dehydration, then the dewatered fabric is soaked in water, described
The pH value that citric acid adjusts the fabric is added in water；It is added after citric acid adjusts the pH value of the fabric and continuously adds in water
Alkyl phenol polyoxyethylene ether carries out the fabric soft；Fabric carries out soft fabric and takes out, and is formed after dehydration, the sizing
Temperature is 170-180 DEG C.
A kind of described method for adjusting fabric bleaching pH value using citric acid, it is characterised in that the pH value of the fabric is
6-7。
A kind of described method for adjusting fabric bleaching pH value using citric acid, it is characterised in that the pH value of the fabric is
6.5。
A kind of method adjusting fabric bleaching pH value using citric acid, it is characterised in that described to be washed again with water
In washing, the temperature of the water is 70-80 DEG C, and wash time is 15-20 minutes.
A kind of method adjusting fabric bleaching pH value using citric acid, it is characterised in that the temperature of the water is 70
℃。
A kind of described method for adjusting fabric bleaching pH value using citric acid, it is characterised in that the setting temperature is
170℃。
It is compared with the traditional technology, the method that present invention application citric acid adjusts fabric bleaching pH value increases adjusting and knits
The pH value of fabric is controlled in target range, reduces the xanthochromia degree of fabric in the subsequent process by the technique of the pH value of object.
Specific embodiment
The method of present invention application citric acid adjusting fabric bleaching pH value, comprising the following steps:
1) fabric is washed in alkaline solution；
2) fabric washed in alkaline solution is taken out, dehydration, then is washed with water, the temperature of water is
70-80 DEG C, wash time is 15-20 minutes；
3) it is taken out described again with the fabric that water washs, dehydration, then the dewatered fabric is soaked in water,
The pH value that citric acid adjusts the fabric is added in the water, the pH value of fabric is 6-7；Citric acid be citric acid, citric acid or
Hydrochloric acid；
4) it is added after citric acid adjusts the pH value of the fabric in water and continuously adds alkyl phenol polyoxyethylene ether to described
Fabric carries out soft；
5) fabric carries out soft fabric taking-up, is formed after dehydration, and the setting temperature is 170-180 DEG C.
Preferably, the pH value of fabric is 6.5.
It is citric acid that the present embodiment, which is selected,.When adjusting the pH value of fabric, 0.05 gram of citric acid is added in every liter of water, by PH
Value is adjusted to 6.5 or so.Because citric acid is highly soluble in water, there is special light lemon tart flavour, can be had with covering fabric itself
Special peculiar smell, so that fabric has light apple aroma.
Fabric is washed in alkaline solution, and alkaline agent penetrates into fabric, and alkaline agent accelerates fabric under the high temperature conditions
Oxidation, and then aggravate xanthochromia.In order to improve the whiteness of fabric, it is additionally added fluorescent whitening agent in washing, remains in fabric table
The fluorescent whitening agent in face is easier to lead to xanthochromia.Fabric bleaching method of the present invention washes fabric with 70-80 DEG C of hot water,
It can be effectively removed the alkali penetrated into fibrous inside, while the fluorescent brightening for remaining in fabric surface can be effectively removed
Agent.Preferably, select the temperature of water for 70 degrees Celsius in the present embodiment.
In fabric ready-made clothes, stamp garment piece need to also be baked after being formed at 160 DEG C, PRINTED FABRIC bake have it is bright
Aobvious xanthochromia, and some garment pieces need stamp for certain clothings, some garment pieces are not required to stamp, when two garment pieces meet system
Apparent color difference after the meeting when on to dress.The present invention allows fabric xanthochromia being formed by the way that setting temperature is increased to 170 DEG C
When just occur, the color difference between garment piece can be reduced.Color difference after the textile printing of different batches in this way bakes also is under control,
Simple stamp garment piece and the garment piece for being not required to stamp can directly meet system, without due to the xanthochromia of stamp garment piece to being not required to stamp
Garment piece is baked, to substantially increase production efficiency, is reduced costs.
It is compared with the traditional technology, the method that present invention application citric acid adjusts fabric bleaching pH value increases adjusting and knits
The pH value of fabric is controlled in target range, reduces the xanthochromia degree of fabric in the subsequent process by the technique of the pH value of object.
