Abstract

The invention discloses efficient de-waxing cleaning solution for wax printed fabrics, which is formed by fully stirring chelating dispersant, sodium gluconate, C12-14 secondary alcohol polyoxyethylene ether, secondary alkyl sodium sulfonate (SAS), polyvinyl pyrrolidone, N-vinyl pyrrolidone, alkali-resistant defoaming agent, water and the like. The composition has very good de-waxing effect on the wax printed fabrics, can improve the whiteness of the wax printed fabrics, has good boiling performance on background color dyes, and can improve the brightness and fastness of the background color of the dyes.

Description

A kind of wax seal fabric is with efficiently moving back the wax scavenging solution

Technical field

The present invention relates to a kind of wax scavenging solution that efficiently moves back, particularly a kind of wax seal fabric is with efficiently moving back the wax scavenging solution.

Background technology

Wax seal figured cloth complex manufacturing, with high content of technology, adopt traditional resist printing technology, impermeable wax (main component is a rosin) is imprinted on the cotton grey fabric surface by layout, dyed then, get rid of the wax line, dye the wax line, move back wax, tens road technical process such as chromatography pattern process.The boiling allotment of the apolegamy of waxy feed and wax liquid is the key that guarantees wax seal figured cloth quality.The kind of wax is a lot, and as rosin, paraffin, river wax etc., what each producer generally adopted at present is rosin.Rosin is to be refined by natural pine gum processing to form, and is faint yellow block, and softening temperature is 70-90 ℃, and fusing point is 100-105 ℃, good film-forming property, but be difficult for eccysis from the fabric.

At present, domestic wax seal is produced and is adopted vertical double-sided rotary screen wax seal machine mostly, prints identical wax liquid flower shape at the fabric pros and cons earlier, makes wax liquid flower type cooling film forming through the cold water spray then, obtains splendid mechanical resist printing ability.Use vat dyes pad dyeing such as indigo, India Blue IBN then, what make that the wax seal fabric obtains the pros and cons unanimity dyes the duplicate printing effect thoroughly.Print the wax fabric subsequently and enter and get rid of the wax operation, do not have the resist printing effect, in follow-up wax line dyeing course, be able to painted owing to get rid of the wax line slit that wax produces.Finish vat dyes pad dyeing and wax line painted after, should be in time with residual wax place to go from the fabric, so that following process.At present, each producer generally adopts the cold water rope to wash and moves back wax.After moving back wax, still have a small amount of wax not to be removed clean, seal wax place fabric whiteness does not reach requirement, if carry out follow-up stamp, the decorative pattern Dry Sack withers secretly, low quality.At present, most of printing and dyeing enterprises only adopt heat alkali liquid that wax seal cloth is further cleaned and move back wax, and it is undesirable to move back the wax effect, and wax seal place fabric whiteness is relatively poor.

Summary of the invention

The purpose of this invention is to provide a kind of wax seal fabric with efficiently moving back the wax scavenging solution, wash in the process at thermokalite and to add, that can obviously improve the thermokalite cleaning process moves back the wax effect, print wax place fabric whiteness after improving alkali cleaning, simultaneously on the ground colour vat dyes that dyes have the soap boiling function, improve its coloured light and bright-colored degree, improve its fastness ability.

The present invention efficiently moves back wax scavenging solution basic role principle and comprises:

1. have certain chelating rainwater function, the softening washing water improves detersive efficiency;

2. rosin and saponification rosin are had stronger emulsification washing ability, in solution, easily form micella, make the eccysis from the fabric of rosin wax;

3. have anti-contamination ability, prevent that the rosin in the emulsion from attaching fabric again;

4. certain alkaline resistance properties can be used simultaneously with heat alkali liquid, has extremely strong infiltration, emulsification, de-oiling and synergetic;

5. the indigo vat dyes that waits is had excellent cleaning effect, effectively the eccysis loose colour is adjusted dyestuff at the fibrous inside existence, fastness abilities such as the friction of raising dyestuff, washing.

Wax seal fabric of the present invention comprises various ingredients with efficiently moving back the wax scavenging solution, is respectively described below.Chelated dispersants is the powdery polycarboxylate, molecular weight 30, and 000-50,000, working substance content is not less than 95%, and the per-cent that accounts for gross weight is 4.0-10.0%, is preferably 6.0-9.0%.Sunmorl N 60S has the effect of collaborative chelated metal ions, and the per-cent that accounts for gross weight is 2.0-5.0%.C12-14 secondary alcohol Soxylat A 25-7 is the nonionogenic tenside of environment-friendly high-efficiency, and wherein the average value of polyoxyethylene is 9, and the per-cent of this ingredients constitute gross weight is 10.0-20.0%, is preferably 15.0-18.0%.Seconary Alkane Sulphonate Sodium SAS is an anion surfactant, has good infiltration, the ability of deoiling under alkaline condition, and the per-cent that accounts for gross weight is 3.0-6.0%.Polyvinylpyrrolidone is a high molecular polymer, has good anti-stain characteristic energy, and suitable molecular weight is 7, and 000-54 between 000, is preferably 28,000-34,000; The per-cent that polyvinylpyrrolidone accounts for gross weight is 5.0-15.0%, is preferably 10.0-14.0%.The N-V-Pyrol RC can be worked in coordination with polyvinylpyrrolidone and be improved stability and action effect, and the per-cent that accounts for gross weight is 3.0-6.0%.Alkaline-resisting defoamer is common silicone based defoamer, can prevent that above-mentioned composition from producing too much foam in preparation and use, and its per-cent that accounts for gross weight is 0.1%.Above component and percentage range are based on that a large amount of experiment basis determine, can make processed wax seal figured cloth quality obtain obviously to improve.

Advantage of the present invention is: can obviously improve the wax seal figured cloth and move back the wax effect in alkaline cleaning procedure, make seal wax place fabric obtain higher whiteness, also the ground colour dyestuff be played good soap boiling effect simultaneously, promote every fastness index of ground colour.
