Abstract
The present invention discloses a reeling auxiliary agent, and relates to the technical field of silkworm cocoon reeling cocoon cooking auxiliary agent. The reeling auxiliary agent and an auxiliary agent total composition thereof includes 10-90 wt.% of a fluorocarbon surfactant. The reeling auxiliary agent provided by the invention has high acid and alkali resistance and stability, and can solve the problem of instability effect in improving cocoon unwinding rate and improving the performance taste of raw silk under different conditions.
Description
Technical field
The present invention relates to silk cocoon filature cocoon cooking aid technical field, especially a kind of take fluorocarbon surfactant as the filature cocoon cooking aid of main raw material.
Background technology
The process extracting silk from silk cocoon is called filature, filature uses the mode of poach usually, the high temperature of water is utilized on the one hand to kill silkworm chrysalis in cocoon, on the other hand because silk is animal fiber, containing a large amount of animal colloid albumen, by heating, make wherein most of colloid albumen soluble in water, thus play defibre, extract the object of silk smoothly out.Because silk cocoon is except fibrous fibroin albumen and be adhesive in except the sericin of periphery, still containing a small amount of grease class, pigment, inorganic matter etc., wherein the oil substances such as primary alconol class, solid fatty acid, wax, liquid fatty acid has the function of the infiltration that discharges water, so, add some can promote water permeation or promote silk gum swelling, dissolving, even sex change of degrading filature cocoon cooking aid to accelerate cocoon cooking process or to improve cocoon cooking effect.
At present existing filature auxiliary agent has on the market: the bleeding agent series be made up of surfactant: amber Diisooctyl sulphonic acid sodium (penetrant t), and pancreas adds fat A(by oleic acid or oleoyl chloride and isethionic acid condensation product), the addition product of bleeding agent JEC(higher aliphatic and oxirane), Nekal BX (naphthalene sulfonate); The reeling agent series be made up of alkali ion compound: sodium metasilicate, ammoniacal liquor, natrium citricum etc.; There is the inhibitor series controlling silk gum dissolution degree: glacial acetic acid, sodium bisulphite formaldehyde (rongalite), formaldehyde etc.If what regulate silk cocoon by the Acidity of Aikalinity of the above surfactant of single use or organic chemical reagent boils state, really can achieve the goal, but deposit higher to conditional requests such as temperature, pH value, hardness of water, site of action in use, acid-fast alkali-proof is poor, the shortcomings such as poor stability, the counter productive such as easily cause sericin modification, fibroin and silk-fibroin structural failure, cocoon cooking excessive.Therefore, there is the compound filature auxiliary agent be made up of many raw materials afterwards, as ZSC-901 cocoon cooking aid, JCS-971 reeling agent, Osgen-p auxiliary agent etc.These compound filature auxiliary agents have certain scope of application, comparatively obvious to the silk cocoon action effect difference of different regions, and functionally also have some limitations, and make it on popularity uses, be subject to larger restriction.
Summary of the invention
The invention provides a kind of filature auxiliary agent, this filature auxiliary agent acid-fast alkali-proof and stability higher, can solve at different conditions to improving the reelability percentage of silk cocoon and improving the problem of effect instability of raw silk performance taste.
In order to solve the problem, the technical solution adopted in the present invention is: include the fluorocarbon surfactant that mass ratio is 10% ~ 90% in its auxiliary agent total composition of this filature auxiliary agent.
In order to solve the problem, the technical solution adopted in the present invention is: described fluorocarbon surfactant is perfluorinated sulfonic acid sodium.
Further: described fluorocarbon surfactant is perfluorocarboxylic acid sodium.
Further: described fluorocarbon surfactant is the mixture of perfluorocarboxylic acid, perfluorocarboxylic acid sodium and perfluorinated sulfonic acid sodium.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
Fluorocarbon surfactant is exactly replace the surfactant of hydrocarbon chain as non-polar group in molecule using fluorocarbon chain.Relative to other surfactants, fluorocarbon surfactant the most outstanding feature is: efficient, stable, i.e. high surface, high thermodynamic and chemical stability.This peculiar property of fluorocarbon surfactant is directly relevant to fluorocarbon chain, fluorine element is the element that electronegativity is the strongest, it has high oxidation gesture, high ionization energy, it is polarized that this characteristic is that fluorine atom is very difficult on the one hand, polarity is very low, so fluorocarbon chain hydrophobic effect is strong, mutual molecular force is weak, which results in the surface tension that just significantly can reduce the aqueous solution under extremely low application concentration, and there is high surface-activity, aqueous solution surface tension can be dropped to pole low-level, aqueous solution surface tension can be made to be down to 15 ~ 16dyn/cm as perfluorocarboxylic acid.Cause fluorine-carbon bond (F-C) bond energy high (in fact fluorine-carbon bond is the covalent bond that known bond energy is the highest) on the other hand, fluorocarbon chain structure is highly stable, be mainly manifested in following 3 aspects: one is that heat endurance is high, as perfluorinated sulfonate can not decompose at 350 ~ 400 DEG C, perfluorocarboxylic acid is energy stable existence under 400 DEG C of environment, and perfluorocarboxylic acid salt also can be applied in the high temperature system of 250 DEG C; Two is that chemical stability is good, can stablize in the special applications systems such as strong acid, highly basic, Strong oxdiative medium and effectively play its Action of Surfactant, can not react with system or decompose, in 98% sulfuric acid solution containing chromium oxide (10G/L), at 90 DEG C of temperature, deposit 28 days its performances as perfluorinated sulfonate and any change does not occur; Three is that compatibility is good, and high chemical stability just means high chemical inertness, and fluorocarbon surfactant can be compatible well with other all kinds of activating agent, and can be applicable to nearly all formula system.So, this filature cocoon cooking aid of the present invention can play the capillary effect of good and stable reduction water at different conditions, guide or increase the penetrability of cocoon layer water, make inside and outside cocoon, between cocoon layer, rapid infiltrated between silk and silk, and uniformity, and then when guaranteeing cocoon cooking, silk cocoon is heated consistent and uniform, improves the taste of raw silk performance.
