Abstract
A method for removing scales from human hair include the steps of pretreatment, washing in water and combing, and features that the degradation function of compound protease is used to puff and deform the scales of human hair and after hydrolysis the scales are removed without use of strong acid and alkali. Its advantages are less loss of hair, no damage to hair in strength and no environmental pollution.
Description
The present invention relates to the manufacture field that the people sends out, a kind of specifically people of removing sends out the process of appearance scale layer.
At present, people all adopt the chemical method of strong acid, highly basic effect on the desquamation technology that the people sends out, and its shortcoming is, the people send out weightless big, distortion level is big; It is impaired that the people sends out fibre tension, reduces the intensity that the people sends out, and empty G﹠W is polluted, and the health to the operative employee has certain harm in addition.
The objective of the invention is, utilize biotechnology, make the people send out scale layer bulking generation hydrolysis and remove.
Technical scheme of the present invention is, the desquamation method that a kind of people sends out comprises processes such as preliminary treatment, washing, comb draw, and its special character is, utilizes a kind of degradation that mainly contains the compound protease of thiolase, α-protease, removes the people and sends out scale layer.
The consumption of compound protease is more than 2.5% (OWF).
The action time of compound egg enzyme was at 60～90 minutes.
The pH value of the effect body lotion of compound protease is between 4.5～7.5.
The operative temperature of compound protease is at 40～60 ℃.
The structure that the people sends out can be divided into: wei shanny lamella, cuticula, cortical layer, medullary substance layer.Desquamation is exactly to remove the wei shanny lamella that the people sends out appearance.Because the effective object of enzyme is wei shanny lamella and a little cutin, cutin is a kind of protein of angling, and it resolves into several amino acids through the catalyzing hydrolysis of enzyme under certain conditions, and its course of reaction is softer steadily, and the people is sent out fiber can not work the mischief.The commentaries on classics selectivity of enzyme has determined it only to act on keratoprotein, and can not act on the cortex that the people sends out, and has reduced the weightlessness that the people sends out.The mechanism of enzyme is to carry out under the condition of neutrality or weak acid, weak base, has avoided the pollution to environment.
Because the characteristics of the selectivity catalysis of enzyme, restricting the completeness of reaction, whole atoms and the gene of forming the protein molecule in the alpha-Keratin of scale, the arrangement on three dimensions, distribution and peptide bond move towards difference, the i.e. space conformation of protein, structure difference.Thereby need different enzymes to make catalyst, the compound protease that needs plurality of enzymes to combine.Assert a kind of compound protease that mainly contains thiolase, α-protease through the screening combination.
Because it is protease generally is indifferent equilibrium, better during temperature T=40～60 ℃.Through testing under this temperature, the pH value of body lotion is lower less than 4.5 o'clock protease activities, and when the pH value of body lotion protease activities greater than 7.5 time descends, the pH value of Lip river liquid is in 4.5～7.5 protease activities the bests.
After the processing time of enzyme reaches 90 minutes, time expand protease very little to the effect that the people sends out, the time of therefore determining was at 60～90 minutes.
The consumption of protease is 2.5% when following, and its speed of action is slow, is unfavorable for producing, and increases protease concentration, and the speed of action of protease is accelerated, so the consumption of protease should be more than 2.5% (OWF).
The people sends out and carries out pretreated water earlier wash before the enzyme effect, washes after the enzyme effect again, combs and draw, dry, put in storage or change over to down operation.
Concrete technological process is: (1) people flood wash preliminary treatment → → (2) enzyme handles → → (3) washing → → (4) comb draws → → (5) oven dry → → (6) finished product → → (7) put or change over to down operation in storage.
Owing to take technique scheme, can realize that a kind of people sends out strong, weightless little, the handling safety of pulling force, the people who reduces environmental pollution again sends out the desquamation method.
Further specify below in conjunction with embodiment.
Embodiment 1, get the people and send out 10 kilograms, 1 kilogram of pretreatment fluid (JFC+NH4CL) mixes the control bath temperature at T=40 ℃, pH value=9.0 dippings washing taking-up in 20 minutes by 1: 10 bath raio, puts into 90 kilograms soft water, the enzyme that adds 2.5% (OWF), control enzyme liquid temp is at 40 ℃, and control enzyme liquid pH value evenly soaked 60 minutes 4.5, bled off body lotion, hot water (about the 80 ℃) washing that adds 90 kilograms again discharged water in 20 minutes, and last combing oven dry gets product.
Embodiment 2, get the people and send out 13 kilograms, 1.3 kilograms of pretreatment fluids (JFC+NH4CL) mix the control bath temperature at T=50 ℃, pH value=8.5 dippings washing taking-up in 25 minutes by 1: 10 bath raio, put into 87 kilograms soft water, the enzyme that adds 4% (OWF), control enzyme liquid temp is at 60 ℃, and control enzyme liquid pH value evenly soaked 90 minutes 7.5, bled off body lotion, hot water (about the 80 ℃) washing that adds 87 kilograms again discharged water in 15 minutes, and last combing oven dry gets product.
Embodiment 3, get the people and send out 10 kilograms, 2 kilograms of pretreatment fluids (JFC+NH4CL) mix control Lip river liquid temp at T=40 ℃, pH value=9.0 dippings washing taking-up in 20 minutes by 1: 10 bath raio, put into 90 kilograms soft water, the enzyme that adds 3% (OWF), control enzyme liquid temp is at 50 ℃, and control enzyme liquid pH value evenly soaked 70 minutes 6.4, bled off body lotion, hot water (about the 80 ℃) washing that adds 90 kilograms again discharged water in 10 minutes, and last combing oven dry gets product.
Embodiment 4, get the people and send out 13 kilograms, 2.6 kilograms of pretreatment fluids (JFC+NH4CL) mix the control bath temperature at T=50 ℃, pH value=8.5 dippings washing taking-up in 25 minutes by 1: 10 bath raio, put into 87 kilograms soft water, the enzyme that adds 6% (OWF), draw the enzyme liquid temp at 55 ℃, control enzyme liquid pH value evenly soaked 80 minutes 7, bled off body lotion, boiled water (about the 80 ℃) washing that adds 90 kilograms again discharged water in 20 minutes, and last combing oven dry gets product.
