The process is simple and reasonable, and can save mass energy and reduce environmental pollution.

Description

Face towel refining process at low temperature in refining tank

Technical field

The invention belongs to textiles pretreatment technology field, is a kind of face towel refining process at low temperature in refining tank that utilizes specifically.

Background technology

Cotton towel must pass through refining processing, removes the commensal (pectin, cotton seed hulls, pigment, ash grade) of cotton fiber, to improve water imbibition, the whiteness of towel, is convenient to follow-up seal, dyes processing.Concise jar of traditional technology all is high-temperature process, and power consumption is big.Though the cold-pad-batch process temperature is low, need earlier towel to be padded experienced liquid, clot then uses the plastics paper bag tight, is put into indoor 24 hours of 40-50 degree, and this mode of production time is long, and is also more loaded down with trivial details, and the production product whiteness is poor, and the uniformity also is difficult to guarantee.

Summary of the invention

At the deficiency of prior art, the invention provides a kind of face towel refining process at low temperature in refining tank.

Below introduce a kind of face towel refining process at low temperature in refining tank of the present invention in detail, finish as follows:

A, required concise towel are put in the jar uniformly;

Liquid is practiced in B, preparation, according to the bath raio of 1:4-6, puts into demineralized water in pill tank, adds the hydrogen peroxide stabilizer of 1.5-3mL/L successively; The hydrogen peroxide of 10-14mL/L; The NaOH of 10-16g/L; The surfactant of 2-5mL/L;

C, the experienced liquid that will prepare infiltrate concise jar at the bottom of jar earlier by material-compound tank, ooze 10-20 minute, then remaining experienced liquid start are squeezed in concise jar;

D, open and stop after vapour is warmed up to the 30-40 degree;

E, ON cycle pump will be practiced liquid upper and lower circulation in jar, and preceding 3 hours, circulate and stopped half an hour in 1 hour, back 12 hours is to circulate to stop half an hour half an hour, total time is 15 hours;

F, concisely after the stipulated time, raffinate is drained;

G, the towel that concise jar is interior are washed once in 40 degree warm water, wash in normal-temperature water once;

H, towel is taken out concise end from jar.

Advantage of the present invention is to utilize concise jar of rationally adjusting process prescription and operational procedure, has worked up the towel process at low temperature in refining, and the product quality of production has reached requirement, saved a large amount of energy, drop to the 30-35 degree by traditional 105-110 degree, one ton of yarn of every processing can be saved steam 1.2T.Overall economic efficiency is per ton save 300 surplus yuan.Technology advantages of simple of the present invention can be saved a large amount of energy, reduces environmental pollution.
