Abstract
The invention relates to a method for evaluating the density of animal fur. The density of the animal fur is evaluated by a tool named a measuring scale through the following three steps of: firstly, intersecting a main scale and an auxiliary scale which are separated to select an area to be detected; secondly, parallelly moving a movable handle of the auxiliary scale to extrude the selected area, and reading a scale, namely the measured density; and finally, calculating the number of hairs contained in the selected area, namely the fur density in the traditional sense, through a ratio of compaction area to the average cross sectional area of a single hair. The measured density can replace the fur density in the traditional sense, and a method for quickly, simply, nondestructively and accurately measuring the density of the animal fur is obtained.

The scheme that technical solution problem of the present invention is adopted:
The invention process, is mainly finished by dip stick by the evaluation of gross density animal.The dip stick main body is made up of main scale and secondary chi.A kind of method of evaluating animal fur density is used for animal and is measured by gross density and the fur quality evaluation.It is characterized in that
To select the zone by after the hair compacting, according to after the compacting and the area ratio before the compacting, read by the hair compacted density, as the index of evaluation animal fur quality.It is characterized in that according to area after the compacting of the resample area of animal fur particular area with through the particular animals colony single hair weighted mean cross-sectional area of measuring and calculating, measuring and calculating unit fur area by the hair root number, i.e. traditional sense by gross density.Can realize of the present invention by hair compacted density and traditional being converted by gross density.It is characterized in that using the instrument of a kind of animal fur sampling and density measurement, directly read by gross density.Of the present invention by hair compacted density and traditional linear by gross density, available mensuration density directly replaces fur density to the animal fur flavor evaluation.It is characterized in that by by hair compacted density measuring and calculating traditional by the reduction formula of gross density, comprise on average by the measure formula of gross density, coarse wool density, cashmere density and hetero typical fibers density.
Estimation steps comprises: finish animal by the horizontal selection of hair by the U-shaped handle of main scale earlier, the secondary chi perforation of vertically inserting main scale U-shaped handle of U-shaped handle by secondary chi is finished animal by vertical selection of hair then, move to fixed handle the removable handle in the secondary chi U-shaped handle is parallel at last, the compacting hair, read the scale on the main scale U-shaped handle, can obtain animal of the present invention by the measured value of gross density, its size can be used as the evaluation animal by the index of gross density, finish animal by the evaluation of hair quality, be used for replacing animal by gross density.Can certainly choose the radical that area contains hair by recently calculating of compaction area and single hair xsect, promptly traditional by gross density.
Advantage of the present invention has: the present invention has remedied classic method evaluation animal by the shortcoming that the hair workload is big, accuracy rate is not high, required time is long, loss is big.Later on the evaluation animal during by hair quality, can replace traditionally fully with the reading on the dip stick by gross density, finish fast animal by the evaluation of hair quality.

The removable handle b of the 1-handle 2-U type handle A 3-U type handle B 4-scale 5-secondary chi perforation 6-secondary chi fixed handle secondary chi of a 7-8-hinge 9-track is filled the removable handle of bolt 10-track 11-operational zone
Specific implementation method
As shown in Figure 3, the used dip stick of 11 removable handle operational zone the present invention is made up of main scale and secondary chi, and main scale interts together by the perforation on the main scale is vertical with secondary chi.1 is that handle, 2 is that U-shaped handle handle A, 3 is that U-shaped handle handle B, 4 is that scale, 5 is secondary chi perforation among Fig. 1.
6 is that secondary chi fixed handle a, 7 is track for the removable handle b of secondary chi, 8 fills bolt, 10 for hinge, 9 for track among Fig. 2
The size of the used dip stick each several part of the present invention should be done corresponding adjustment by the length of hair according to animal, and relative dimensions is described by the dip stick of gross density with evaluation otter rabbit: the main scale handle is of a size of 6cm * 3cm; The width of main scale U-shaped handle A, handle B is 1cm, and length is 6cm; Groove width 1cm in the U-shaped handle; Main scale thickness is 0.4cm; Secondary chi perforation 5 is 3cm * 0.2cm; Secondary chi handle a, handle b and handle spacing are 1cm; The length of handle a, handle b is 4.73cm, and thickness is 0.2cm; The diameter of outer rail is respectively 0.1cm and 0.2cm in the track 10; Removable handle b is 0.2cm * 1cm at the stiff end of track; The holder of U-shaped handle is of a size of 3cm * 1cm * 0.4cm.Related angle except that thickness direction is done mellow and full processing, other all be 30 °.
When animal was evaluated by gross density, at first hand-held main scale handle was along by the hair surface, i.e. tangential direction, and by laterally the selecting of hair, key points for operation are that the lower surface of main scale will be close to animal by the root of hair to animal, it is soft that action is wanted.Secondary then chi will slowly pass the secondary chi perforation 5 from main scale, uses the same method and utilizes secondary chi that the quilt hair is vertically selected, and the removable handle b of the secondary chi of this process fixes, and promptly requires track to fill bolt 9 and is filled in the track.So just select, separated of fixed-area by the territory, hair-fields by mutually perpendicular major and minor chi.Next track is filled bolt 9 and screw out from track 10, this moment, secondary chi removable handle b just can move to secondary chi fixed handle along track 10, noticed that this crosses range request pair chi and will be close to main scale U-shaped handle A.The removable handle b that press...withes one's finger is arranged in the part 11 of main scale U-lag, and it is moved to fixed handle a along track 10, to being pushed by hair between the major and minor chi, makes by the hair compacting.At last, reading the scale that is positioned on the main scale U-shaped handle A can instead traditionally be used when animal is evaluated by hair quality by the index of gross density.Can certainly calculate traditionally by gross density according to the reader on the dip stick, concrete formula is as follows:
