Abstract
The invention discloses a cotton fabric short-flow pretreatment auxiliary agent and a process thereof. The pretreatment auxiliary agent includes the following components by the weight percentage: 20%-40% of sodium carbonate, 30%-40% of sodium metasilicate, 3%-7% of sodium persulfate, 3%-7% of sodium citrate, and 10%-40% of a surfactant. With synergic use of the auxiliary agent and 100% hydrogen peroxide, good desizing, scouring and bleaching effects can be achieved. The pretreatment process comprises the steps: preparing a working liquid by the auxiliary agent with the concentration of 7.5-17.5 g/L and the 100% hydrogen peroxide with the concentration of 8-12 g/L, carrying out two dipping and two rolling, steaming for 40-80 min, washing with water, and drying.
Description
Technical field
The present invention relates to the short flow process of a kind of COTTON FABRIC pre-treatment auxiliary agent and technique thereof, belong to the pre-treatment process formula technique field of COTTON FABRIC dyeing and finishing industry.
Background technology
Weaving approximately containing the cellulose commensal of 10% left and right, is mainly pectin substance, nitrogen substance, waxy substance, inorganic salts, pigment, cotton seed hulls etc. with cotton fiber, and the existence of these impurity has had a strong impact on the performances such as COTTON FABRIC hydrophilic absorbent, appearance luster.
In order to remove the impurity in cotton fiber, improve the hydrophilic absorbent performance of COTTON FABRIC, meet people's the requirement of taking, need to carry out pre-treatment (destarch, kiering and bleaching) to COTTON FABRIC.Traditional cotton pretreatment is to carry out under the condition of highly basic, main employing caustic soda and surfactant kiering, the mode of bleaching, utilize caustic soda, for the decomposition of pectic substance, protein and to the saponification of fatty acid ester material in wax and surfactant, the effects such as the emulsification of the middle-and-high-ranking fatty alcohol of wax, higher fatty acids and hydrocarbon, dispersion are removed to the impurity such as lyophobic dust on cotton fiber, improve wettability.This technique has good pre-treatment effect, but needs lot of energy, water and chemical reagent, and operating process is long.The theory of the environmental protection and saving such as in recent years, the abbreviated system of cotton pretreatment is because its flow process is short, energy consumption is low, and water consumption is few is paid close attention to widely.Also very active with the developmental research of pre-treatment auxiliary agent for the short flow process of COTTON FABRIC.The present invention be directed to a kind of new and effective pre-treatment auxiliary agent in the exploitation of COTTON FABRIC short-flow pre-treating process.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of new and effective pre-treatment auxiliary agent for the short process pretreatment of COTTON FABRIC, the pre-treatment process that uses this auxiliary agent is provided simultaneously, the problems such as in solution traditional handicraft, chemical assistant consumption is large, and energy consumption is large, operating process complexity.
To achieve the above object, one aspect of the present invention provides a kind of new and effective COTTON FABRIC short flow process pre-treatment auxiliary agent, comprises following composition by weight percentage:
As preferred version, above-mentioned pre-treatment auxiliary agent, each compositions in weight percentage is:
In above-mentioned formula:
Described surfactant comprises following component with percentage by weight note: alcohol ether carboxylate (APG) 20%, alkyl poly glucoside (AEC) 40%, removing oil-removing wax agent (FMES) 40%.
The present invention provides the technique of auxiliary agent of the present invention in the short process pretreatment of COTTON FABRIC on the other hand, by concentration, be that 7.5～17.5g/L auxiliary agent of the present invention and concentration are that 8～12g/L100% hydrogen peroxide is mixed with working solution, through two, soak two and roll, through decatize 40～80min, washing is dried.
Preferred process program is: by concentration, be that 17.5g/L auxiliary agent of the present invention and concentration are that 12g/L100% hydrogen peroxide is configured to working solution, soak two roll through two, through decatize 60min, washing is dried.
The present invention compared with prior art, has following remarkable result:
1, auxiliary agent of the present invention belongs to environmental protection auxiliary agent, without highly basic, not containing harmful substances such as APEO, formaldehyde, heavy metals.
2, application auxiliary agent of the present invention is only used with 100% hydrogen peroxide simultaneously, just can reach whiteness, the gross efficiency standard of traditional handicraft.
3, use auxiliary agent of the present invention simple to operate, and flow process is few, has improved pre-treatment working (machining) efficiency, reduces the consumption of steam, water, auxiliary agent etc., reduce production costs.
The specific embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail, but the present invention is not only confined to following examples.
COTTON FABRIC index test standard is as follows:
(1) whiteness: adopt Datacolor SF-600 Computer color testing instrument test whiteness, light source D65, represents with CIE whiteness value.
(2) capillary effect: measure the height that in 30min, solution rises along fabric warp-wise according to FZ/T01071-1999 " textiles capillary effect test method ".Measure 3 times, average.
(3) tearing brute force: with reference to ASTM D1424-1996 " impact pendulnm method is measured the tearing brute force of fabric " standard test.
