Abstract
The invention relates to the technical field of spinning, particularly to a low-temperature bleaching formula and technology for cellulose fiber spunlace nonwoven fabric. The low-temperature bleaching formula for the cellulose fiber spunlace nonwoven fabric is characterized by comprising 0.5-5 g/L of caustic soda, 5-20 g/L of 30% hydrogen peroxide, 2-20 mu mol/L of Schiff base metal complexes, 1-2 g/L of a stabilizer and 0.5-2 g/L of a penetrating scouring agent. Compared with the prior art, the low-temperature bleaching technology has the advantages as follows: the low-temperature technology is adopted for scouring and bleaching, the technology is shortened, steps are simple, treated cellulose fibers or nonwoven fabric meets subsequent production requirements, and the working efficiency is greatly improved. With the adoption of the low-temperature technology, the flow is shortened, consumption of water, electricity and steam is substantially reduced, damage to the cellulose fibers is reduced, and the product quality can be improved.
Description
Technical field
The present invention relates to textile technology field, specifically a kind of cold bleaching formula for cellulose fibre spunlace non-woven cloth and technique thereof.
Background technology
Cellulose fibre spunlace non-woven cloth, the particularly conventional production process of cotton spunlace non-woven cloth be first by raw cotton opening picking, comb and parallel cotton fibers prior to spinning, cross lapping, multiple roll drawing-off, degreasing bleaching, then water sting, dry, reel, obtain finished product.Namely all foreign material, impurity are bleached together, this technique generally will through 5-6 hour, temperatures as high 98-100 DEG C, and some factories are even up to 105 DEG C, and not only length consuming time, water, electricity, the vapour energy are high, and waste is large, and cost is high.The sequencing of degreasing bleaching and water thorn operation is exchanged by another technique, and established technology is improved to raw cotton, opening picking, comb and parallel cotton fibers prior to spinning, cross lapping, multiple roll drawing-off, water thorn, degreasing bleaching, oven dry, winding, finished product.Avoid with cotton the problem that fine impurities when being raw material not easily removes, and further increase the cleanliness factor of product.But degreasing bleaching process still carries out boiling in drift pot, the density of yardage roll and the requirement such as shaping differ, and the energy consumptions such as the yardage roll of different densities need adopt different technique, and operation easier is high, and the time is long, water, electricity, gas are high, and production cost is high.The boiling and bleaching process that research is applied to fabric is innumerable, but rarely has people to study application about the boiling and bleaching process of non-weaving cloth.
Summary of the invention
The present invention is for overcoming the deficiencies in the prior art, and adopt low temperature process to carry out kiering, bleaching, process shortens, step is simple, and the cellulose fibre after process or nonwoven fabric meet the requirement of subsequent production, greatly provide operating efficiency.
For achieving the above object, design a kind of cold bleaching formula for cellulose fibre spunlace non-woven cloth, it is characterized in that: bleaching formulation is made up of caustic soda, 30% hydrogen peroxide, Schiff base metal complexes, stabilizing agent, infiltration scouring agent, and its content is respectively: caustic soda is 0.5 ~ 5g/L; 30% hydrogen peroxide is 5 ~ 20g/L; Schiff base metal complexes is 2 ~ 20 μm of ol/L; Stabilizing agent is 1 ~ 2g/L; Infiltration scouring agent is 0.5 ~ 2g/L.
Described Schiff base metal complexes is amino acids presence of Schiff-base complex, comprises schiff bases copper complex, schiff bases cobalt complex and the violent complex of schiff bases.
Described stabilizing agent is sodium metasilicate or magnesium chloride or organophosphor acids stabilizing agent.
Described infiltration scouring agent is the combination of one or more surfactants of isomery 13C alcohol polyoxyethylene ether (9EO), isomery 13C alcohol polyoxyethylene ether (7EO), plant polyenoid phenol non-ionic surface active agent.
The concrete steps of cellulose fibre bleaching are as follows:
(1) working solution of preparation bleaching according to a certain percentage, is added in bucking kier;
(2) in bucking kier, drop into cellulose fibre, cellulose fibre is 1:5 ~ 10 with the weight ratio of bleaching working solution;
(3) temperature of the bleaching working solution in bucking kier is raised to 60 ~ 80 DEG C, the processing time is 60 ~ 120 minutes;
(4) cellulose fibre after kiering, bleaching is carried out washing, dewater stand-by;
(5) the cellulose fibre carding after dehydration, water are stung into nonwoven fabric;
(6) nonwoven fabric after being stung by water is dried, winding, finished product.
Cellulose fibre nonwoven fabric concrete steps are as follows:
(1) working solution of preparation bleaching according to a certain percentage, is added in bucking kier;
(2) in bucking kier, drop into the nonwoven fabric roll of non-degreasing bleaching, nonwoven fabric roll is 1:5 ~ 10 with the weight ratio of bleaching working solution;
(3) temperature of the bleaching working solution in bucking kier is raised to 60 ~ 80 DEG C, the processing time is 60 ~ 120 minutes;
(4) nonwoven fabric roll after kiering, bleaching is washed;
(5) nonwoven fabric roll after washing carried out drying, reel, finished product.
Compared with the existing technology, adopt low temperature process to carry out kiering, bleaching, process shortens, step is simple, and the cellulose fibre after process or nonwoven fabric meet the requirement of subsequent production, greatly provide operating efficiency in the present invention.Low temperature process not only shortens flow process, and the consumption first mate of water power vapour reduces, and decreases cellulose fibre damage, is conducive to the raising of product quality.
