Description

Tanning method for fowls'down (s)

The invention provides a kind of method of tanning of fowl velour leather, particularly the process for tanning of goose down skin.

With the fur tanning of domestic animal (as sheep, rabbit, dog, cat etc.) become fur goods with wild beast such as fox, sable, squirrel etc.) fur tanning become fur goods that also comparative maturity of each procedure that the history of centuries, its fur tanning becomes the employed process for tanning of fur goods, production technique, production has been arranged.But, for the fur of the fur of poultry, particularly goose because dermatotome is thin, fat is thick, be mingled with the feather of sturdy length in the fine hair, so traditional idea is considered as the forbidden zone to the tanning of poultry velour leather all the time.

The objective of the invention is: the process for tanning that a kind of poultry velour leather is provided.

Technical scheme of the present invention is: utilize immersion, degreasing, degrease (fleshing), pickling, chrome tanning, the secondary degreasing of existing tanning fur, production technique such as raw meat, stuffing, drying, perching, arrangement are gone in bleaching; On the basis of existing tanning fur processing method, increase is coated with operations such as subcutaneous lipids etching reagent and epilation, because be mingled with some feathers in the fine hair on the fowl velour leather (goose down skin), these feathers are not removed, and can influence the velour leather Products Quality.And feather is longer also more deeply, more firm in dermatotome than the sturdy root that fledges of fine hair, and after coating etching reagent on the dermatotome, the also the most perishable unrest of feather root is easy to be pulled out from dermatotome.

The method of tanning of fowl velour leather of the present invention is:

1. be coated with the subcutaneous lipids etching reagent: on dermatotome, be coated with etching reagent, make the fat on the dermatotome can rotten random one deck, and main be to make the feather root that is mixed in the fine hair disorderly rotten, reduce the bonding force of feather and dermatotome;

2. dial hair: the direction along hollow billet pulls out feather;

3. in going: the rotten random lipid layer on the dermatotome is shoveled;

4. immersion: because the velour leather process storage root of Dahurian angelica, dehydration is bigger, need be placed on to promote to soak in the liquor, makes the water-filling degree of velour leather and weave construction approach the fresh hide state;

5. degreasing: put velour leather in detergent solution bubble wash-out fat;

6. degrease: the loose lipid layer on the dermatotome is shoveled;

7. pickling: velour leather is placed in acid and the neutral salt solution soaks, be that chrome tanning prepares suitable pH-value, make the further dehydration of dispersion and collagen of collegen filament;

8. chrome tanning: velour leather is put in the chrome tanning liquid soaks, purpose is to improve the tensile strength of velour leather, anti-water heat-resisting property etc.;

9. dry: the velour leather behind the chrome tanning is carried out seasoning, and hair is done up to 70%, and solarization dermatotome again turns over;

10. perching: the dermatotome perching that drying is good, shovel pine are prepared for secondary degreasing;

11. secondary degreasing:, must carry out secondary degreasing because the grease of fowl velour leather is bigger;

12. raw meat is removed in bleaching: velour leather is put into scrubbing powder solution bubble flush away raw meat deodorize;

13. stuffing: go the velour leather of raw meat to carry out stuffing bleaching and handle;

14. dry: the velour leather after the stuffing processing is carried out drying, dermatotome is dried to 70% earlier, dry fine hair again turns over;

15. perching: the dermatotome perching of the velour leather that drying is good;

16. arrangement: the velour leather to perching is put in order, dials and removes residual hollow billet and off-color marking.

The method of tanning of fowl velour leather of the present invention can become the velour leather goods with poultry velour leather, particularly tanning goose down leather, and the velour leather goods have that dermatotome is thin and soft, fine hair is fine and close and magnificent, is well warming and adornment of human body.
