Abstract
The invention discloses an after-finishing process of linen fabric. The used finishing liquid includes lemon acylation degradation chitosan finishing liquid and compound finishing liquid of lemon acylation degradation chitosan and citric acid. The after-finishing process of the linen fabric has the advantages that the invention provides an after-finishing process of the linen fabric without toxicity or formaldehyde release, the process well maintains the green environmental protection characteristics of the linen fabric, the used lemon acylation degradation chitosan finishing liquid can obviously improve the resistance of the linen fabric to deformation, also can improve the defects of easy crease and poor wearability of the linen fabric in the wearing process; besides, the finished fabric has higher whiteness and can ensure various mechanical properties to meet the requirements. The process also can maintain stable color of the fabric and has lasting finishing effect and higher washing fastness of the finished fabric.
Description
Technical field
The present invention relates to a kind of sodolin postfinishing process.
Background technology
Sodolin feel nature, dress is refreshing very, comfortable, rough, have powerful high, advantage such as absorb-discharge humid is good, thereby have natural fabric queen's good reputation.But since linen fibre to exist content of cellulose low, the pectin content height, the fiber degree of polymerization, degree of crystallinity, the degree of orientation are all than many deficiencies such as cotton fiber height, linen fibre elasticity in the past is all very low, crease recovery is also relatively poor, wrinkling easily in dress and the washing process, need flatiron also to bring many inconvenience after washing to the consumer, cause the good characteristic of sodolin to fail to find full expression.In order to solve this difficult problem, in the 60 to 70's of last century, people have designed the postfinishing process of sodolin, and this technology mainly is divided into physics (machinery) arrangement and chemical finishing two classes.Wherein most pronounced effects is chemical finishing.At first, the chemical finishing agent that people use mainly contains formaldehyde resin, epoxy resin, organosilicon and polyolefin series etc., and these contents all have report in patent documents such as SU80680, J01077680, CN1066093A.But these finishing agents in use all have a common deficiency, are exactly all can discharge formaldehyde in the use, thereby all very unfavorable to health and environmental protection.In order to overcome this drawback, someone has designed crease proofing agent based on polycarboxylic acid, because a plurality of carboxylic groups in this finishing agent can interact with the form of fiber molecule with covalent cross-linking, thereby can promote the elastic return of fabric fibre molecule effectively, solved the wrinkle resistant problem of sodolin well, relevant report is seen Chinese patent (CN1624010A).Shitosan then shows remarkable antibacterial functions as another green ring-like guarantor's fabric finishing agent, has now also begun to be employed, as CN1664225A and CN1687512A etc.Though above-mentioned two kinds of formaldehydeless release type finishing agent of linen cloth have been realized two kinds of different functions of modern flax post-finishing agent respectively, also do not see open report at present as a kind of flax finishing agent and finishing technique thereof that has antibiotic and wrinkle resistant group simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of sodolin postfinishing process, not only can improve sodolin after this technology arrangement creases easily in wearing process, take shortcomings such as poor morphology, and can accomplish not destroy the environmental protection characteristic of sodolin.
Employed dressing liquid has two kinds in the technology of the present invention, and a kind of is lemon acidylate degrade chitosan dressing liquid, and its composition and weight proportion are:
Finishing agent lemon acidylate degrade chitosan consumption 2-5%,
Catalyst sodium hypophosphite consumption 2---6%.
Another kind of dressing liquid is lemon acidylate degrade chitosan and the composite dressing liquid of citric acid, and its composition is to add the 0.5-2% citric acid in above-mentioned dressing liquid again.
It is solvent that arrangement is bathed with water, adds above-mentioned dressing liquid, and dressing liquid is 1: 20 with the ratio of water, can also can add softener and/or bleeding agent in arrangement is bathed.
The application of above-mentioned Anti-bacterial and Crease liquid in the sodolin postfinishing process comprises following three steps:
(1) sodolin is carried out dressing liquid and pad processing, adopt two to soak two roll process, pick-up 80-90%,
(2) fabric is carried out preliminary drying; The preliminary drying temperature is 75-85 ℃, and the time is 120-180 second.
(3) fabric is carried out high temperature and bake, baking temperature 160-180 ℃, bake time 120-180 second.
Employed finishing agent lemon acidylate degrade chitosan is developed by the applicant in the above-mentioned technology, has antibiotic wrinkle resistant two kinds of functional groups in the molecular structure of this finishing agent simultaneously.This finishing agent is that the concrete steps of its preparation are with the trim of citric anhydride as degrade chitosan:
(1) degrade chitosan and medium are mixed by 1: 20～40 mass ratio, stir swelling 0.5h;
(2) 1: 2～5 mass ratio adds citric anhydride to press degrade chitosan and citric anhydride;
(3) add the catalyst that accounts for gross mass 1～3%, normal temperature condition is reaction 16～24h down;
(4) stop reaction, regulate the pH value to neutral, suction filtration, decompression concentrate, and the 60mL ethanol of adding is placed and spent the night suction filtration, vacuumize.
Synthetic method the applicant of above-mentioned finishing agent has submitted patent application to State Intellectual Property Office, application number is 200810064928.0, the present invention is the continuation research to above-mentioned technical theme, and a kind of concrete application process of a kind of this flax finishing agent in flax postfinishing process is provided.
The invention has the beneficial effects as follows that at existing in prior technology defective and deficiency a kind of sodolin postfinishing process of nontoxic, formaldehydeless release is provided, and this technology has kept the environmental protection characteristic of sodolin well.In addition, lemon acidylate degrade chitosan dressing liquid used in the present invention can improve the resistivity of sodolin to deformation significantly, can also improve sodolin and crease easily in wearing process, takes shortcomings such as poor morphology.In addition, arrangement back fabric all has higher whiteness, and can guarantee that every mechanical performance reaches requirement, and this method can also keep the colour stable of fabric, and finishing effect is lasting, and arrangement back fabric washing fastness is higher.
