Description

Loose one-step pretreatment production system for chemical fiber fabric

Technical Field

The utility model relates to a loose formula one-step process pretreatment production system of chemical fiber fabric belongs to the technical field of weaving printing and dyeing.

Background

The chemical fiber fabric is made of high polymer which is a byproduct in petroleum, natural gas and coking industry and is made of textile fiber through chemical treatment and mechanical processing, and is generally divided into artificial fiber and synthetic fiber fabric, the chemical fiber has high strength and good rebound resilience, the fabric made of the chemical fiber has good crease resistance and wear resistance, and the made clothes are characterized by stiffness, corrosion resistance, insulation, easy washing, small shrinkage, good hygroscopicity and air permeability, and the like, so the chemical fiber fabric is widely popular with consumers.

The current production methods are as follows: the method I adopts a full-flow process of a high-temperature high-pressure overflow dyeing machine: gray fabric is put into a cylinder, heated and circularly washed, refined agent is added for about 30 minutes, high-temperature circularly boiled for about 30 minutes at 120 ℃, temperature is reduced for about 60 minutes, liquid is discharged, fresh water is added for heating and washing, liquid is discharged, alkali liquor is added for alkali decrement, liquid is discharged, fresh water is added for heating and washing, liquid is discharged, fresh water is added for washing, acid is added for regulating the pH value, liquid is discharged, fresh water is added for washing, the gray fabric is taken out of the cylinder (or dyed), dehydrated, opened and subjected to post finishing; the method II adopts the full-flow process of the high-temperature high-pressure airflow dyeing machine, and the production method and the process are basically the same as the method I; the third method adopts a full-flow process of a high-temperature high-pressure jig dyeing machine: the grey cloth is fed into a cylinder in open width, washed with hot water at 60 ℃ for 1 drainage, added with a refining agent and boiled for 4 drainage at 120 ℃, replaced with fresh water and heated to 90 ℃ for 2 drainage, added with alkali liquor for alkali decrement for 4 drainage, replaced with fresh water, heated and washed for 3 drainage, replaced with fresh water and washed for 2 drainage, added with acid for pH value adjustment, replaced with fresh water and washed for 2 drainage, taken out of the cylinder (or dyed), and fed into the subsequent finishing; the method IV adopts a special open-width desizing refiner, desizing and deoiling are finished in the refiner, then the reduction is carried out by a special alkali reducing machine, and the subsequent finishing is carried out;

the first, second and third methods have problems: (1) each process point needs to add water, raise temperature, lower temperature and drain water, and a large amount of water and steam are consumed and a large amount of high-temperature sewage is discharged when one cylinder of fabric is produced; (2) the addition of the auxiliary agent and chemicals at each process point is discharged, so that the auxiliary agent and chemicals cannot be reused, and the difficulty and cost of sewage treatment are increased; (3) the production time of each cylinder is long, the fabric in each cylinder needs about 4 hours, and a large amount of electric energy is consumed by a circulating pump and dehydration; (4) because the process control points of each cylinder are more and the control error is more, the cylinder difference between the cylinders is difficult to control, and the product quality is reduced; (5) long time consumption and low production efficiency; (6) the occupied area of the equipment is large, and land resources and unit yield are wasted.

The fourth problem is that: (1) because the pretreatment adopts open-width compact process production, the relative flow is short, the fabric cannot be treated thoroughly and has hard hand feeling, (2) the process after dyeing is also to carry out reduction washing, soaping and washing in a cylinder, and then the fabric is taken out of the cylinder, dewatered and opened and then enters the subsequent finishing, so the same problems of the first, second and third methods exist, and the dewatering and opening need to consume a large amount of energy consumption and manpower.

In summary, the key to solve the above problems with several existing production methods is to improve the production process and to make the whole production process continuous and reasonable as much as possible, so we are very urgent to propose a loose one-step pretreatment production system for chemical fiber fabrics.
