System fur material leather quality inspection
System fur leather raw materials of various kinds,the plate shape,mass,and the use value is not the same,so,in testing the quality,there are different leopard requirements and methods.
A,xiaomao fine leather
Xiaomao fine leather strip shape most for tubular skin,a few for open piece of leather.Drum skin has two kinds:plate out after the file(or don't open rear bumper)drum skin and hair out after the file of the drum skin.
(a)identification plate out drum skin quality identification method of the pile quality,mainly according to the wool to take off the change process,pedal show characteristics of dew,and in a small amount of the actual situation of external plush,plush to determine the length and density.This kind of skin easily found on the pedal various existing disability,can be directly according to the weight of the disabled,to judge the system the influence degree of the fur coat.And the hair in the drum skin wool in various defects in the inside of the skin tube,inspection is directly observed,this needs according to the disability in the pedal and part of the exposed wool characteristics reflect,to judge.Through the observation of the panel color variation,the strength of the light,listen to the voice of the pile friction and help to set the disability of the category,the character and degree.Such as the pedal local has become dark,water wet trace,show that the parts of the wool already by boring and fall off.

Appraisal wool quality,a shake,two,three,four see touch blow.
1.Shake skin to fur on the(MaoChao,plate down),the right hand DE live after hip,left hand knead kiss nose,with the wrist and jitter hides,plush restore natural state.
2.See observation hair length,density,luster,and presence of flow needle fly wool phenomenon,the length of the old guard hair,wool composition proportion,tail length and whether fleeciness,etc.

4.Mouth blow on hide a bit suspicious phenomenon appears,blow to open plush,check the pedal and fluffy degree of disability and vitality.
Appraisal pedal quality,in addition to check the pedal thickness,elastic strength,but also to flip view panel color,oily size and fine tough degree.
Board quality good xiaomao fine leather,should achieve panel meticulous,thickness uniformity,oil,is white or light color.Poor quality pedal,is weak thin thin or thick hard,uneven thickness,the pan is rough,no oil,the dark.
Xiaomao fine leather piece of picture is small,the presence of disability to system fur value influence is bigger,so in appraisal quality,to disable the type,area,nature,existing parts etc,have strict requirements.
To disable processing general principles are:(1)in the purchase specification allows within the scope of the mechanical damage for wide,the soft strict injury.(2)for distribution in minor parts of the disability requirements wide,for distribution in the main parts of the strict disability.(3)on disability requirements wide,to disperse disability strict.
(3)area computation method according to the fur acquisition ship as stipulated in the case of the plate quality weak for late spring and early fall skin skin.Pedal thicker hard,a purple red or blue,elasticity is poor.Board quality dealing for summer skin or body condition difference two sick animal hides,pedal is weak,the toughness is poor,little fat content.
Second,the heavy hair fine leather
According to hide production season,plush and pedal quality determine the level.
(a)on the wool quality requirements of the test piece fine leather wool quality,basically is fullness plush,plush slightly weaknesses or slightly short thin,plush weaknesses or short thin three levels to show.

Board quality dealing for summer skin or body condition difference,sick animal hides.Pedal is weak,the toughness is poor,little fat content.
(3)the disable processing principle and xiaomao fine skin the same.
(4)area calculation method hides length,most of the heavy hair fine skin is measure ear to end the root of the linear distance.From the waist appropriate site measure the width.Long by wide that find out hides area.
