Abstract
A kind of broad wool treatment process that is used for woolfell, fur are being carried out the fixing processing of broad wool with the formaldehyde fixed agent that contains chitosan under 160～200 ℃ on the presses behind formic acid-ethanol flatiron glazing broad wool.
Method of the present invention, formaldehyde amount ratio usual method reduces 1/3～2/3, and operationlocation's concentration of formaldehyde is below 3mg/l.
Description
A kind of broad wool treatment process that is used for woolfell after using formic acid-ethanol glazing broad wool, is being carried out the fixing processing of broad wool with formaldehyde-chitosan fixing agent under 160～200 ℃ on the presses.
Woolfell after tanning, the fleece bending, lackluster.With the goods, particularly sheep shorn velvet goods that this fur is made, do not reach the appearance requirement of commodity.Therefore, need through particular processing.Comprising: hair stretches, and the hair glazing also makes hair be fixed up at straight configuration.For reaching this purpose, adopt formic acid-Ethanol Method under flatiron, to carry out glazing, broad wool usually.For broad wool is fixed up, adopt formaldehyde or other fixing agent to spread upon on the fleece, on presses, press down in 190～210 ℃.Now produce the fixing agent of employing based on formaldehyde-formic acid-alcohol mixeding liquid.Though this aldehyde-acid fixative has broad wool fixed effect preferably, owing in fixing agent, contain relatively large formaldehyde, so smear with iron process in the formaldehyde volatile quantity bigger, operator's health is had harm.Though some low formaldehyde or formaldehydeless fixing agent can be eliminated formaldehyde pollution and harm, the undesirable or more high reason of cost is difficult to adopt aborning owing to the broad wool fixed effect.
Broad wool fixing agent used in the present invention is to be the fixing agent of major ingredient with formaldehyde and chitosan.Formaldehyde content in this fixing agent reduces 30～70% than normally used formaldehyde fixed agent, low 20～30 ℃ of the comparable general method of ironing temperature.Use broad wool fixing means of the present invention, can eliminate the harm of formaldehyde, save the energy, reduce production costs the operator.
Broad wool fixing means of the present invention mainly is to adopt a kind of new broad wool fixing agent, adds the chitosan of formaldehyde amount 2～5% in formaldehyde solution.Because chitosan is a kind of natural macromolecular material, has good film-forming properties, therefore, PARA FORMALDEHYDE PRILLS(91,95) has certain absorption and set effect after smearing, and can reduce the volatilization of formaldehyde when flatiron.Simultaneously, chitosan contains amino and hydroxyl isoreactivity group, can with the free formaldehyde effect, the residual quantity of minimizing formaldehyde on fleece helps aftertreatment.
Chitosan is the chitosan that makes through dilute hydrochloric acid decalcification, sig water deproteinated, concentrated base deacetylation with shrimp, crab shell.The molecular weight of this chitosan is 20～800,000, and is water-soluble, after viscosity is big, is directly used in preparation broad wool fixing agent poor effect.Therefore, must be suitable with molecular weight degradation to 300～20000 of chitosan.Because of chitosan is soluble in the sour water, so usually chitosan is dissolved in 1% the aqueous formic acid, with the aqueous formic acid of preparation chitosan-containing 1～2%.It is more convenient than directly adding chitosan to use this chitosan solution.
Fasten method for straight wool of sheepskin of the present invention, preparation broad wool fixing agent before broad wool is fixing.In 1000 parts of (weight) broad wool fixing agents, contain 40～80 parts in formaldehyde, 2～3 parts of chitosans, 150～250 parts in formic acid, 200～300 parts of ethanol.Actual preparation is to adopt 37～40% industrial formol, 1% chitosan formic acid solution, 95% industrial formic acid and 95% industrial alcohol in the production.Broad wool fixing agent formaldehyde consumption is different with the broad wool degree of depth and select according to fleece thickness.Fleece is sparse, the broad wool depth as shallow, and the formaldehyde consumption can be less; Otherwise the formaldehyde consumption suitably increases.Chitosan dosage can increase and decrease with the formaldehyde consumption.After prescription is selected, take by weighing material, mixing is standby.The said fixing agent is spread upon on the fleece that formic acid-ethanol glazing broad wool is handled, under 160～200 ℃, pressing on the presses then, handle by usual method thereafter.Through the fleece that this method is handled, its hair can keep straight configuration for a long time.
Broad wool fixing agent of the present invention can be used with tensio-active agent, gloss-imparting agent etc., to improve perviousness or fleece glossiness.
Embodiment 1
Take by weighing 38% industrial formol 200 parts of (weight), 200 parts in 95% industrial formic acid, 300 parts of 95% industrial alcohols, 2 parts of chitosans, 298 parts in water, place in the porcelain enamel barrel, be stirred to chitosan and all dissolve.Then, be applied on the fleece that formic acid-ethanol glazing, broad wool are handled, under 160～180 ℃, press and get final product.
Embodiment 2
Take by weighing 38% industrial formol 150 parts of (volume), 200 parts in 95% formic acid, 250 parts of 95% industrial alcohols, 250 parts of 1% chitosan solutions, 150 parts in water, place in the porcelain enamel barrel, stir, carry out the fixing processing of broad wool by example 1 method.
Reference examples:
38% formaldehyde 400 parts of (volume), 200 parts in 95% formic acid, 300 parts of 95% industrial alcohols, 100 parts in water behind the mixing, are applied on the fleece that formic acid-ethanol glazing, broad wool are handled, and press to get final product under 190～210 ℃.
When the flatiron, the operating space is got the air sample and is measured formaldehyde content to example 1,2 and reference examples.The embodiment air formaldehyde concentration is 2.1mg/l; Reference examples is 7.4mg/l.Fleece is carried out the sense organ inspection, and the broad wool effect is identical, and embodiment gloss is better than reference examples, and embodiment fleece formaldehyde flavor is slight, and reference examples has the formaldehyde pungent taste.
Claims (3)
1, a kind of broad wool fixing means of woolfell, use the formaldehyde fixed agent to press processing at presses, it is characterized in that: the broad wool fixing agent is made up of by major ingredient formaldehyde, chitosan, is applied on the fleece of broad wool, under 160～200 ℃, on presses, press fixing the processing.
