The method of estimating density of fur

 

The invention relates to the field of fur industry, textile, garment industry, and agriculture and is used for determining the density of hair natural and artificial fur when research on the stages of sorting, quality assessment. This method allows you to measure the density of hair natural and artificial fur without fracture, to expedite the evaluation process, to get an objective direct measures of the density of the hair and lint and hair in General, and also to determine these parameters directly on the animal. Assessment method fur thickness includes the selection area the investigated area fur, picking up the tuft of hair from this area, consolidating them in the beam and determining the amount of hair on which to calculate the density of the fur by the formula G = n/S where n is the total number of hair in the beam ntotal= nbarb+ ndown, PCs; S - area of the investigated area fur, cm2. Additionally determine the diameter down and the top coat. The selection area of the investigated area are done on the fur. In fixed vertical beam hair assess the cross-sectional area of the two levels defined by the location of the base of your hair and guard number (nbarb) and down (ndown) perform by formulaswhere nbarbthe number of guard hairs, PCs; SPuccathe cross-sectional area of the beam at the end of downy hairs, mm2; SOsti- cross-sectional area of the top coat, mm2,where SPucca- the cross-sectional area of the beam at the end of downy hairs, mm2; SPucca- the cross-sectional area of the beam at the position of the base of the hair, mm2; SPuja- the cross-sectional area down hair, mm2. The technical result of the method is non-destructive quantification of the density of the fur on the stages of sorting, evaluation of the quality of the appraisal animals, accelerate the evaluation of this indicator by eliminating manual counting of hair. 3 Il., table 2.

FIELD: production of fur articles.

SUBSTANCE: method involves applying fur strips with its side opposite to pile surface to substrate surface and attaching said strips on surface by wrapping with thread stitch loops at outside for closing at least part of substrate surface with piles of strips; applying each fur strip onto substrate surface for defining alternating rectilinear and looped portions; providing attachment of said strips along the entire length of rectilinear portions, with fur strips being arranged along width of substrate at frequency directly proportional to density of fur article to be manufactured.

EFFECT: reduced labor consumption and wider range of fur articles.
