Abstract
The invention discloses a preparation method for guar gum for fabric caring. The preparation method comprises the following steps: guar gum and a solvent are mixed; basic catalysts are added; the temperature is raised to 30-50 DEG C; cross-linking agents are added; the reaction is carried out for 2-7h; the pH value of the system is adjusted to 8-10 through neutralizers; etherifying agents are added; the temperature is raised to 55-70 DEG C; the reaction is carried out for 2-4h with heat preservation; the pH value is adjusted to 7-8 through neutralizers; the reaction liquid is subjected to filtration, washing and drying, and the guar gum for fabric caring is obtained. The prepared guar gum has similar molecular structure with cellulose. When the guar gum is used in a fabric caring agent, netty macromolecule elastic membranes can be formed on clothing fiber surfaces easily, thus the clothing has good elasticity, and therefore the clothing is not easy to deform after washing, and the guar gum has very obvious effects in cleaning aspects.
Description
Technical field
The present invention relates to the preparation method of guar gum for a kind of fabric nursing.
Background technology
Fabric care agent be to fabric suffered damage in washing process (as lose shape, wrinkling, run look, balling-up, shrinkage or expansion etc.) play the material of protection or repair.Fabric care agent is in the market varied, but generally apply the preparation of micromolecular compound polymerization, as patent CN1402774A, CN1409753A, CN1422329A, the Fabrid care composition that CN1255158A etc. announce, although effect is pretty good, but very easily cause residually, to human body, cause potential harm.Along with the increase of whole world environmental consciousness, people have focused on attention on environment amenable natural macromolecular material gradually.Guar gum is wherein a kind of.
Guar gum is a kind of leguminous plants, is natural polygalactomannan, is mainly grown in India and Pakistani arid area, the main chain of its chemical structure is (1,4)-β-D seminose is unit, and side chain is formed and joined with (1,6) key and main chain by α-D semi-lactosi.The study on the modification of guar gum is to launch based on its different application purpose, and the guar gum of modification is mainly used in the aspects such as household chemicals, oil field chemical, paper industry, mining, and obtains large-scale market recognition.There is in recent years explanation in the formulas such as daily, makeup, food to contain a small amount of modified guar, but do not disclose the preparation method of this modified guar.
Summary of the invention
The technical problem to be solved in the present invention is to provide the preparation method of guar gum for a kind of fabric nursing, the above-mentioned defect existing to overcome prior art.
For solving the problems of the technologies described above, the preparation method of guar gum for fabric nursing of the present invention, comprises the steps:
1) by the former powder of guar gum and solvent;
2) add basic catalyst, be warming up to 30-50 ℃, add linking agent, reaction 2-7 hour;
3) by neutralizing agent regulation system pH value, be 8-10, add etherifying agent, be warming up to 55-70 ℃, insulation reaction 2-4 hour;
4) with neutralizing agent, regulating pH value is 7-8.
5) reaction solution after filtration, washing, obtain described fabric nursing guar gum after drying.
In technique scheme, the weight content of each component is as follows:
Described solvent is selected from least one of methyl alcohol, ethanol, Virahol, sherwood oil or acetone.
Described basic catalyst is selected from least one of sodium hydroxide, potassium hydroxide, diethanolamine, trolamine or diethylenetriamine.
Described linking agent is selected from least one of epoxy chloropropane, formaldehyde, the inclined to one side phosphorus of trichlorine or tripoly phosphate sodium STPP.
Described neutralizing agent is selected from one or more mixture of hydrochloric acid, sulfuric acid or glacial acetic acid.
Described etherifying agent is selected from the chloro-2-hydroxypropyl-trimethyl ammonium chloride of 3-, 2, at least one of 3-epoxypropyltrimethylchloride chloride, Dimethylaminoethyl Methacrylate monochloro methane quaternary ammonium or Dimethylaminoethyl Methacrylate Benzyl Chloride quaternary ammonium.
Guar gum has the molecular structure similar with Mierocrystalline cellulose, has determined that it and Mierocrystalline cellulose have natural sympathy.Guar gum with cationic charge after modification very easily forms net high-polymer elastica on clothes fiber surface for fabric care agent, makes clothing have good elasticity, thereby not yielding after washing.Because this product has certain cationic degree, aspect decontamination, there is very significantly effect, there is the net effect of antistatic, sterilization, sterilization simultaneously.
