Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0014] Such as figure 1 As shown, a dyeing and finishing pretreatment process that can reuse wastewater, the process steps are as follows: firstly, the fabric is sent to the open-width scouring machine 2 for scouring, and the pretreatment liquid during scouring uses bugong tea saponin As a pre-treatment aid; the fabric is boiled and rolled out of excess moisture and then enters the padding machine 3 for padding treatment; the fabric is steamed in the steam box 4 after the padding process is completed and the excess moisture is rolled out. In the example, the top of the steam box 4 is provided with an insulating layer that can prevent condensation water from being produced, so as to prevent the top of the steam box 4 from generating condensation water and dripping on the fabric when the steam box 4 is working, because if any condensation w...

Abstract

The invention discloses a dyeing-finishing pretreatment technology capable of recycling waste water. The technology comprises the following steps that firstly, fabric is conveyed into a full-width boiling machine and boiled; after the fabric is boiled, the fabric enters a padding and impregnating machine and is subjected to padding and impregnating treatment; after the fabric is subjected to the padding and impregnating treatment, the fabric is conveyed into a steaming box and steamed; after the fabric is steamed, the fabric is subjected to high-pressure washing in three or more washing machines in sequence, and then cloth is discharged. A water inlet of a water tank of the last washing machine is communicated with a clear water pipe, an overflow port of a water tank of the first washing machine is communicated with a water storage barrel, water in the water tank of the last washing machine can forward overflow to all the washing machines in sequence and is used for washing, waste water in the water storage barrel can be pumped into a waste water storage tank and stored, waste water in the waste water storage tank can flow into a first chemical material cylinder and a second chemical material cylinder through fall difference separately and is used for recycling chemical materials. According to the pretreatment technology, pretreated waste water can be recycled, during dyeing, the edges of pretreated fabric cannot be easily rolled, the fabric is good in permeability, and the dyeing defect cannot be easily generated.

Description

technical field [0001] The invention relates to the field of fabric dyeing and finishing processes, in particular to a pre-dyeing and finishing process in which waste water can be reused. Background technique [0002] Fabric pre-treatment is the basis for fabric dyeing, printing and finishing. The steps of the existing fabric pretreatment process are usually: first put the fabric into the overflow machine with pretreatment liquid for cooking, drain the liquid after cooking, and then wash the fabric three times, and after each washing, you need to The liquid is drained, and finally the fabric comes out of the cylinder. The existing fabric pretreatment process has the following disadvantages: (1) Since the scouring and three times of washing are carried out in the same overflow machine, the waste water generated by scouring and three times of washing needs to be drained, which will not only pollute the environment, And it will greatly waste water resources; (2) The fabric th...
