Description
Technical field
The present invention relates to printing and dyeing pre-treatment field, more particularly to a kind of fabric printing pre-treating method.
Background technology
Conventional fabric printing pre-treating method is oxygen bleaching process, its processing step approximately as：With hydrogen peroxide, caustic soda,
Refining agent, stabilizer high-temperature process（98℃、120min）It is --- washing --- plus white（98℃、20min）--- washing --- acid
Wash --- deoxygenation --- plus soft（40℃、30min）, above-mentioned handling process has the following disadvantages：1, required pre-treatment auxiliary agent（Dioxygen
Water, caustic soda, refining agent, stabilizer etc.）Species is more so that the handling process is a kind of high energy consumption, high pollution, the work of maximum discharge
Skill, does not meet the theory of modern industry environmental protection；2, dioxygen moisture Jie's speed therein is difficult control, before and after the processing fabric
Whiteness is difficult to unanimously, and because the strong oxidizing property of hydrogen peroxide makes fabric be easy to produce oxidation broken hole；3, caustic soda it is strong
Working solution alkalescence is stronger when alkalescence to handle, and is unfavorable for the stability of fabric before and after the processing, the fabric after processing connects with skin
Lack comfort after touch；4, fabric weight-loss ratio is higher after processing, and fibre strength reduction amplitude is larger.
The content of the invention
Goal of the invention：For problems of the prior art, the present invention provides a kind of fabric printing pre-treating method, should
Processing method is simple, cleaning, safe and pollution-free, and the fabric comfort handled out is stronger.
Technical scheme：The invention provides a kind of fabric printing pre-treating method, comprise the following steps：S1：Washing：In bath
Than for 1:Draining after 10 ~ 20min of washing is carried out under conditions of 5.5 ~ 6.5 to fabric；S2：Tea Saponin is washed：It is 1 in bath raio:4.5~
Tea Saponin is carried out to fabric obtained by the S1 under conditions of 5.5 and washes draining after 75 ~ 85min；S3：Washing：It is 1 in bath raio:5.5~
Draining after 10 ~ 20min of washing is carried out to fabric obtained by the S2 under conditions of 6.5；S4：Pickling is neutralized：It is 1 in bath raio:4.5~
Fabric obtained by the S3 is carried out in pickling and draining after 10 ~ 20min under conditions of 5.5.
Further, the S2 includes step in detail below：S2-1：Water, bath raio are added into the fabric washed by S1
For 1:5.5~6.5；S2-2：Tea Saponin is dissolved in 35 ~ 45 DEG C of warm water and is prepared into the Tea Saponin aqueous solution；S2-3：Will be described
The Tea Saponin aqueous solution is added and stirred obtained by S2-1 in the mixture of fabric and water, and bath raio is 1:4.5~5.5；S2-4：By S2-
The mixture of fabric, water and Tea Saponin obtained by 3 is warming up to 90 ~ 100 DEG C, and Tea Saponin washes draining after 75 ~ 85min.90~100
75 ~ 85min is handled at DEG C so that Tea Saponin can farthest play the ability that its own removes grease in fabric.
Preferably, in the S2-2, the weight ratio between the Tea Saponin and the fabric is 1:15~25.Tea Saponin
Rational proportioning can save Tea Saponin usage amount as far as possible removing between fabric on the premise of grease in fabric, save energy consumption
Resource.
Preferably, in the S2-3, the Tea Saponin aqueous solution adds the S2-1 institutes with 90 ~ 100g/min speed
In the mixture for obtaining fabric and water.Being slowly added to of Tea Saponin is conducive to it to be well mixed with fabric, preferably plays its decontamination
Ability.
Preferably, in the S2-4, as the fabric obtained by the S2-3, water and Tea Saponin mixture with 1.0 ~
2.0 DEG C/min heating rate is warming up to 90 ~ 100 DEG C.During slow heating Tea Saponin can more uniformly with fabric
Grease reaction, treatment effect is preferable.
Further, the S4 includes step in detail below：S4-1：Added into the fabric after S3 washings
Water, bath raio is 1:5.5~6.5；S4-2：After into the fabric and the mixture of water obtained by the S4-1, addition acid is neutral to pH
Draining, the time of pickling is 10 ~ 20min, and the bath raio of pickling is 1:4.5~5.5.The purpose that pickling is neutralized is by the pH value of fabric
Adjust the neutrality of human body the most comfortable, the comfort that increase fabric is contacted with skin.
Preferably, the acid is glacial acetic acid.
Further, also included plus soft processing after the S4.It is described to add comprising the following steps that for soft processing：a：To institute
State in fabric obtained by S4 and add water, bath raio is 1:5.5~6.5；b：Added into the mixture of fabric obtained by a and water soft
Agent is well mixed, and bath raio is 1:4.5~5.5；c：The mixture of fabric, water and softening agent obtained by the b is heated to 35 ~ 45
DEG C, and add draining after 25 ~ 35min of soft processing at such a temperature.
Preferably, in the b, the softening agent of addition is the 1 ~ 2% of the fabric weight.
Beneficial effect：Tea Saponin is nontoxic, harmless, nonirritant printing and dyeing pre-treatment field New-type adjuvant, and it is different from passing
The Additives Products such as caustic soda, hydrogen peroxide, the refining agent used in system pretreating technology for printing and dyeing can produce high energy consumption, high pollution, high row
Put, environment can be caused the characteristics of very big harm, Tea Saponin be exactly clean, safety, energy-conservation.
The advantage for carrying out fabric printing pre-treatment using Tea Saponin is as follows：
1, storage, weighing, material are convenient.The multiple auxiliary agents of past pre-treatment, now become to one, weighing, material error it is big
To reduce.
2, working solution is stable.Past uses hydrogen peroxide bleaching fabric, because dioxygen moisture Jie's speed is difficult control, before and after the processing
The whiteness of fabric is difficult to unanimously, and when being handled using Tea Saponin, the acid-base value of working solution is extremely low, quite steady during processing
It is fixed, so that the stability before and after ensure that fabric treating.
3, fabric oxidation broken hole will not be produced, by the big production of the various myriametres of fabric hundreds of in recent years, no matter water quality,
How high hardness is, peroxidating broken hole never occurs.
4, accommodation is extensive.Cellulose fibre, regenerated fiber and chemical fibre are can be suitably used for, it is especially two or more
Fiber mixed fabrics effect is more prominent.
5, fabric weight-loss ratio is reduced.Weight-loss ratio reduces 2-3% compared with common process.
6, fiber strength enhancing.The more conventional technique of this method, processing has fibre strength to improve 8-10%.
7, environment protecting is notable.What this method was produced, which boils the drift more conventional technique of dyeing waste water COD indexs, can reduce by 50% left side
It is right.
