Description
Technical field
The invention belongs to down products dressing processing technology fields, and in particular to a method of removal duck's down peculiar smell.
Background technique
Since duck belongs to Omnivore, feed, insect, earthworm, fishes and shrimps etc. can become the food of duck, and by
Contain fat more abundant in food, thus makes duck and its duck's down with urine smell taste, and industry " urine smell taste " is referred to as
" fatty raw meat " or " duck body odour ".And goose almost free from extraneous odour, main reason is that the feed of goose is based on plant, such as common open country
It is edible that grass, water plant are available for goose, therefore goose and its goose down fat content are few, almost without peculiar smell.
Can at most produce within duck's down 1 year for three seasons, but goose 1 year only produces a season, and the velour yield of every goose is less, goose cultivation at
This height determines that goose down price is significantly higher than duck's down price.In particular, the growth period of goose to maturation at least at 100 days, and duck is only
It is 40 days, to also determine that goose down is more expensive than duck's down.But it has been observed that due to duck's down peculiar smell, that is, smell weight, in addition raiser
Hormone is added in order to accelerate the growth of duck to be no lack of in feed, to more aggravate the peculiar smell of duck's down.
When use duck's down as down products such as down jackets, eiderdown quilt, down feather cushion, down feather pillow or even all kinds of natural feather dolls etc
Dressing when must reasonably be eliminated the unusual smell processing.Gas is utilized through Wan Wang army, Zhejiang Entry-Exit Inspection and Quarantine Bureau etc.
Matter combined instrument and VOC gas detector detect duck's down smell, the results showed that the main component of duck's down peculiar smell itself is carboxylic
Acid compounds and ester type compound.In addition, natural feather Rumen protein fermentation, which decomposes, contains sulfide, nitrogen in the niff generated
Compound and ammoniac compounds etc..Be to the eliminate the unusual smell method of processing of duck's down at present: use removes during washing to duck's down
Smelly dose, grease removal agent, disinfectant and other finishing agents, but if washing is lost thoroughly, all kinds of chemical assistants can remain on natural feather
In, and atypical distinctive odor (peculiar smell) can be given out.
It is paid close attention to for a long time through the applicant and the various analyses through being done shows cultivating, butchering, washing with detection record
The peculiar smell of duck's down can all be generated in (including drying), the link for spelling heap, packaging and storage etc it is corresponding influence, aforementioned
In link, washing is to control the important link of duck's down peculiar smell with drying.
Chinese invention patent application publication No. CN107083689A recommendation has " a method of removal duck's down peculiar smell ", the
One step is to mix duck's down, water and degreasing agent, is cleaned；Second step is by duck's down, water and oxygen after the first step is cleaned
Agent mixing is pre-oxidized；Third step is to mix the duck's down after being pre-oxidized by second step, water, disulfurase, into
Row reaction, the duck's down removed odors.And the patent is taught that: glutamine transaminage can be added simultaneously in the third step
And controlling the mass ratio of glutamine transaminage and water is 0.3-0.5: 1000；By the mass ratio of duck's down and water in the first step
Control is 1: 40-60, and the mass ratio control of degreasing agent and water is 3-5: 1000, scavenging period 30min, cleaning temperature 30-
50℃；It is 1: 20-40 by the mass ratio control of duck's down and water in second step, oxidant (H2O2) and water mass ratio be 0.5-2
: 1000, the temperature of pre-oxidation is 20-50 DEG C, pH3.5, preoxidation time 30min；By the matter of water and natural feather in third step
Amount is 1: 10-20 than control, and the mass ratio of half deamination acid desulfurase and water is 0.5-1: 1000, and reaction temperature is 30-50 DEG C, instead
It is 1h between seasonable.
But there are following shortcoming for above-mentioned patent: first, due to lacking to duck from slaughter to when washing this to natural feather
Restraining factors, that is, control condition of time in section, and directly duck's down, water and degreasing agent are mixed and cleaned, thus wash out
The glossiness of duck's down, the opposite shortcoming of fluffy degree and smell, that is, peculiar smell it is relatively heavy, this is because drake feather from duck slaughter to
Washing institute's interval time is longer, and degree of spoilage is more serious, and peculiar smell is bigger, therefore rationally control duck's down extremely enters from duck slaughter
The time for washing this stage has the effect of getting twice the result with half the effort；Second, since second step uses hydrogen peroxide (H2O2) duck's down is carried out
Pre-oxidation and third step carry out reaction using disulfurase can damage duck's down to a certain extent, because H2O2 belongs to
Strong oxidizer is difficult to control in use, is easy to appear excessively oxidation or oxidation not exclusively, is caused natural feather to become fragile, easily
Yellowing and to return color serious, while can decline to a great extent in next year down content, quality is had a greatly reduced quality.Highly acid after hydrogen peroxide oxidation is dirty
Water, containing a large amount of metal ions, even if discharge again also can cause environmental pollution after treatment.Third, since drying is companion
With after washing, if the technical factor assurance to drying is improper, such as remaining moisture content is excessively high in natural feather, then
Can still ferment rotten, giving forth fragrance after natural feather absorption moisture, then can equally generate accordingly not to the effect that eliminates the unusual smell of duck's down
Benefit influences, therefore drying is overlook either of the two the important link in water-washing process；Although fourth, patent do not refer to packaging and
Storage, but after washing i.e. clean after natural feather be often inevitably related to packaging with storage link, and packaging with
If improper measures in link of storing in a warehouse, can because in natural feather microbial reproduction, decompose due to there is peculiar smell (industry claim this ring
The peculiar smell generated in section is " returning taste "), it will affect its quality after down products is made.
In view of above-mentioned prior art, the applicant has made positive and beneficial exploration and experiment repeatedly, forms finally
Technical solution described below.
