Abstract
The invention discloses a wet and short flow-process pretreatment process of fabric, firstly, boiling-off treatment of the gray fabric is conducted, after that, the gray fabric is washed with water, then, chlorine bleaching treatment is conducted, and then, dechlorination, acid washing of the gray fabric are conducted, lastly, oxygen bleaching treatment is conducted; the components of the oxygen bleaching solution is are follows: H2O2 of 4.0g / l, stabilizer of 2.0g / l, water glass of 3.5g / l, self-made penetrant of 3.5g / l, and pH value of 10.5; the gray fabric which experiences the oxygen bleaching treatment is washed by water, and then is directly mercerized, so as to obtain the finished fabric; the alkali-liquid concentration in the mercerizing liquid is of 160g/l, the self-made penetrant is of 5.0g/l, the speed of vehicle is of 65m/min, and the cloth-surface expander tension is 95% of the gray fabric width; the self-made penetrant is phosphoric-acid composite ester type anionic surfactant; the stabilizer is organic multi-phosphate. The invention fills the gap in study on the self-penetrant, realizes the reform for the high-energy-consumption, high-emission, and low-efficiency pretreatment production process, reduces the energy consumption, and decreases the pressure of resources and environmental-protection.
Description
Technical field:
The present invention relates generally to the pre-treatment of ramie fabric and BLENDED FABRIC thereof, relates in particular to a kind of wet and short flow-process pretreatment process of fabric.
Background technology:
In prior art, the pre-treatment of ramie fabric and BLENDED FABRIC thereof is that grey cloth is carried out that kiering, chlorine are floated, after oxygen floats processing, after the drying process, handles through mercerization again.Because middle drying course makes the process of grey cloth have high energy consumption, maximum discharge and inefficient shortcoming.
Summary of the invention:
The object of the invention is exactly in order to remedy the defective of prior art, a kind of wet and short flow-process pretreatment process of fabric to be provided, and this technology can realize the effect of energy-saving and emission-reduction.
The present invention is achieved by the following technical solutions:
A kind of wet and short flow-process pretreatment process of fabric is characterized in that: carry out according to the following steps successively:
At first, grey cloth is carried out kiering handle, the weight proportion of NaOH and self-control bleeding agent is in the kiering liquid: 10: 1; Steam temperature is 100 ± 1 ℃; Steaming time is 55min;
Secondly, carry out chlorine after the grey cloth after kiering handled is washed and float processing, sodium chlorite consumption 6g/l in the Chlorine Bleach, regulating the pH value is 10.5,20 ℃ of 45min that bank up;
Once more, chlorine being floated grey cloth after the processing carries out carrying out oxygen after dechlorination, the pickling and floats processing, H in the oxygen bleaching liquor
2O
2Consumption 4.0g/l, stabilizing agent 2.0g/l, waterglass 3.5g/l, self-control penetrant m 3.5g/l regulates pH value 10.5, and steam temperature is 100 ± 1 ℃; Steaming time is 50min;
At last, oxygen floated directly carry out mercerising after grey cloth after handle handling is washed and handle, make the fabric finished product; Concentration of lye in the mercerising liquid is 160g/l, self-control bleeding agent 5.0g/l, and speed of a motor vehicle 65m/min, cloth cover expanding tension force is grey cloth fabric width 95%;
Described self-control bleeding agent is a phosphoric acid compound ester type anion surfactant; Described stabilizing agent is an organic multicomponent phosphate.
Described self-control bleeding agent is a phosphoric acid compound ester type anion surfactant, has high alkaline resistance properties and high osmosis energy, and it is stable inadequately to have solved present conventional mercerizing assistant quality, can not satisfy the technological requirement of wet cloth mercerising.
The composition principle of auxiliary aid M is as follows:

The present invention makes oxygen float grey cloth later without oven dry, directly enter mercerization, by adding the self-control bleeding agent, adopt the PLC technology that technological parameter is gathered in real time and monitored, optimization is provided with wet cloth mercerising alkali concn, liquid carrying rate, pads parameters such as time, tension force, improves the fabric mercerization effect.
Advantage of the present invention is:
The present invention fills up the research blank of self-control bleeding agent, has realized the transformation to fabric high energy consumption, maximum discharge, inefficient pre-treatment production technology, reduces energy resource consumption, alleviates the pressure of resource and environmental protection.
Description of drawings:
Fig. 1 is a process chart of the present invention.
The specific embodiment:
A kind of wet and short flow-process pretreatment process of fabric is characterized in that: carry out according to the following steps successively:
At first, the grey cloth of the pure ramie plain cloth of the 27.8tex*27.8tex semi-products after handling singing carries out kiering to be handled, NaOH consumption 30-35g/l, and self-control bleeding agent consumption 3.5g/l, steam temperature is 100 ± 1 ℃; Steaming time is 55min;
Secondly, carry out chlorine after the grey cloth after kiering handled is washed and float processing, sodium chlorite consumption 6g/l in the Chlorine Bleach, regulating the pH value is 10.5,20 ℃ of 45min that bank up;
Once more, chlorine being floated grey cloth after the processing carries out carrying out oxygen after dechlorination, the pickling and floats processing, H in the oxygen bleaching liquor
