Abstract
The invention relates to the technical field of cloth dyeing, in particular to a process for whitening and sizing circular knitted cloth. The process is characterized by comprising the following steps of: whitening the circular knitted cloth in aqueous solution of 0.3 to 0.6 percent of whitening agent and 2 to 3 percent of softening agent at normal temperature under normal pressure, extruding the circular knitted cloth by using double rollers, controlling the pressure to between 0.30 and 0.50MPa to achieve better whitening effect, dehydrating the circular knitted cloth by using a dehydrator, and then performing a hot-air dry pressure sizing process for 20 to 40 seconds at the temperature of between 210 and 220 DEG C.
Description
Technical field
The present invention relates to a kind of technical field of dying cloth, especially a kind of process for whitening and sizing circular knitted cloth.
Background technology
In printing technology, traditional process for whitening and sizing circular knitted cloth is grey cloth to be entered in the bleaching and dyeing machine to brighten earlier, is entering 100～110 ℃ of steamed that are added with brightening agent, and the dehydration back adds softener stirs, and steam shaping is carried out in dehydration again.Such technology has following several outer defective: the whitening and sizing power consumption of cloth per ton is big, needs 10 tons of water, 1 ton of coal, and 1500 degree electricity, 20 people worked 20 hours, and waste water can not utilize.
As the patent No. is the production technology that ZL95110587.6 the invention discloses a kind of knitted cloth, mainly solve in the existing technology shortcomings such as poor flexibility, its main feature is that special knitting process is arranged after the doff operation, after brightening (or dyeing), washing step special softening step, baking operation, three overdetermination type operations is arranged successively.The production technology of this knitted cloth mainly comprises doff, printing, perching, mending, puts, gets the raw materials ready, bleaches, washes, brightens (or dyeing) in storage, washes, puts in storage operation.
Summary of the invention
The objective of the invention is provides a kind of saving energy in order to solve traditional problem that the process for whitening and sizing circular knitted cloth power consumption is big, pollution is many, labor intensive is big, simple to operate, the process for whitening and sizing circular knitted cloth that integrated cost is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of process for whitening and sizing circular knitted cloth, it is characterized in that described cylinder knitting grey cloth is in the aqueous solution of 0.3～0.6% brightening agent, 2～3% softeners, brighten under normal temperature, the normal pressure, push with twin-roll, Pressure control makes better whitening effect at 0.30～0.50MP, with the Water Extraction Machinery dehydration, under 210～220 degree temperature, carry out the hot blast dry-pressing power setting process in 20 to 40 seconds then again.
As preferably, brighten under described normal temperature, the normal pressure, soft technology carries out in same equipment.
Effective benefit of the present invention is: 0.25 ton of water of cloth power consumption per ton, and 500 degree electricity, without coal, 5 people worked 8 hours, and water can constantly reuse, and can realize zero-emission.
Therefore, the present invention is a reasonable in design, and labour intensity is low, and is practical, a kind of process for whitening and sizing circular knitted cloth that integrated cost is low.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is a kind of example structure schematic diagram of the present invention.
1. containers among the figure, 2. grey cloth, 3. pinch roller cylinder, the 4. aqueous solution, 5. guide wheel.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Referring to Fig. 1, present embodiment carries out in same group of equipment, and the aqueous solution 4 is housed in the container 1, and the aqueous solution 4 is for containing the solution of 0.5% brightening agent, 2% softener.
The top installing pinch roller cylinder 3 of container 1, the liquid that pinch roller cylinder 3 squeezes out is back in the container 1, and pinch roller cylinder 3 can be established many groups.
4 li of the depth of water liquid of container 1, install one group of guide wheel 5, can be provided with the guide wheels 5 of many groups according to actual needs, as shown in Figure 2.
During work, brighten under normal temperature, normal pressure, pinch roller cylinder 3 adopts and pushes with the twin-roll form, Pressure control is at 0.30～0.50MP, make better whitening effect, with the Water Extraction Machinery dehydration, the hot blast dry-pressing power setting process that carries out half a minute then under 210 ℃ of temperature gets final product again.
The foregoing description is to explanation of the present invention, is not limitation of the invention, any structure after the simple transformation of the present invention is all belonged to protection scope of the present invention.
Claims (2)
1. process for whitening and sizing circular knitted cloth, it is characterized in that described cylinder knitting grey cloth is in the aqueous solution of 0.3～0.6% brightening agent, 2～3% softeners, brighten under normal temperature, the normal pressure, push with twin-roll, Pressure control strengthens whitening effect at 0.30～0.50MP, with the Water Extraction Machinery dehydration, under 210～220 degree temperature, carry out the hot blast dry-pressing power setting process in 20～40 seconds then again.
