Description
Technical field
The present invention relates to fur tanning technical field more particularly to a kind of tanning manufacturing technique methods of fur.
Background technology
Tanning be tanning agent molecule to intradermal penetration and with rawhide tropocollagen molecule active group in conjunction with and occur property change
Process.Tanning makes to generate cross-bond between collagen polypeptide chain, increases the stability of collagen structure, improve shrinkage temperature and
Hydrothermal stability improves the ability of the chemicals such as antiacid, alkali, enzyme.Rawhide before the tanning of process hides must through immersion, depilation,
A series of preparatory process such as liming, softening, pickling.Tanning mainly has chrome tanning and vegetable tannage, there is also aldehyde tannage, oil tanning,
Aluminum tanning, zirconium tanning, Combined tanning, alum tannage, formaldehyde tanning etc..For example, carrying out tanning processing to fur, fur is made to become bark, tanning
It is related to the processing steps, wherein tanning and stuffing work such as immersion, degreasing, multiple leaching, pickling, softening, tanning, drying, stuffing, the wooden chaff of rolling
Sequence is fur become bark from rawhide determine a ring.Currently, for the furs such as fur process for tanning have complex process,
The shortcomings of difficulty of processing is big, the Harmful Residue is more, larger to the fur damage after processing.Therefore, it is necessary to a kind of new furs
Relevant tanning process.
