Abstract
The invention discloses a method for calculating overfeeding based on measurement of a density ruler. The method comprises the following steps of: firstly, washing a piece of greige cloth; under the condition of being free from influence of an external force, using the density ruler to measure the number of coils per inch along the horizontal direction and the number of coils per inch along the longitudinal direction; taking the measured numbers as critical values and weighting the weight of the greige cloth; and utilizing a formula to calculate the overfeeding according to a density threshold gram weight of the greige cloth after being washed and the threshold gram weight required by an end product of cloth. In such a manner, the method can be used for calculating the overfeeding according to the numbers of the coils of a knitted fabric measured by the density ruler. The overfeeding can be adjusted, thereby scientifically ensuring consistent density and gram weight of the knitted fabric while leaving from a machine.
Description
Technical field
The present invention relates to a kind of measurement, computing method, particularly relate to a kind of method of density rule measuring and calculation overfeeding.
Background technology
Textile is in dyeing and finishing processing, and warp-wise is subject to larger pulling force, causes the elongation of cloth length and fabric width to narrow down.In order to overcome this unsure state, guarantee the dimensionally stable of textile, eliminate fine wrinkle, improve wrinkle resistance, often adopt tentering or setting process to process, and when tentering or typing, need adjust the speed into cloth, Here it is overfeeding.
Advance cloth speed and be called positive overfeeding greater than the speed of a motor vehicle of stenter or forming machine, or overfeeding, contracting code.Positive overfeeding is so that warp thread bounces back, and filling density is risen, and grammes per square metre increases, and warp-wise shrinks and reduces.
Feed if the speed of advancing cloth just is called to surpass in reverse less than the speed of a motor vehicle of stenter or forming machine, or negative overfeeding, draw code.Surpass in reverse and feed so that warp thread extends, filling density descends, and grammes per square metre reduces, and warp-wise shrinks and becomes greatly.
Classic method is to estimate overfeeding by measuring the front door width of cloth grammes per square metre of fabric tentering or typing, claims grammes per square metre with the dise knife sampling again after going out machine, and undesirable words are adjusted again.But fabric is owing to being subject to the impact of internal stress and tension force, and often grammes per square metre can be very unstable, and it is inaccurate that all wait behind the machine weighed grammes per square metre to adjust overfeeding in the machine again.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of method of calculating overfeeding based on measurement of density ruler, can calculate overfeeding according to the coil number of density rule surveyingpin fabric, can science pass through the overfeeding adjustment and allow knitted fabric go out machine the time consistent in density, grammes per square metre consistent.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of method of calculating overfeeding based on measurement of density ruler is provided, has may further comprise the steps:
1) washes first a single blank, measuring its horizontal per inch coil number and warp-wise per inch coil number without under the external force impact with density rule, as critical value, claim to such an extent that wash the weight of rear grey cloth;
2) the door width of cloth grammes per square metre that requires of the density door width of cloth grammes per square metre after then washing according to embryo cloth and finished fabric, using formula calculates overfeeding:
a=（CPI×（1-（1-G1/G×（1-（1-?WPI×π×d×n?/?WPI1×π×d1×n1）×100%））×100%）/CPI1-1）×100%，
In the formula:

D1: need the woven loom diameter of knitted fabric of typing,
N1: need the interior pin number of the woven per inch of knitted fabric of typing,
CPI1: the warp-wise per inch coil number that needs the knitted fabric of typing.
In a preferred embodiment of the present invention, the described concrete grammar of measuring horizontal per inch coil number with density rule is: loosen without external force state lower time when fabric is in, hand-held density rule, density rule is placed on the knitted fabric, face toward slowly mobile density rule of light, make the parallel of lines on the density rule and fabric parallel, can reflect clearly rhombus, the scale shown in the rhombus wedge angle upper and lower side is poor to be horizontal per inch coil number.
In a preferred embodiment of the present invention, the described concrete grammar of measuring warp-wise per inch coil number with density rule is: loosen without external force state lower time when fabric is in, hand-held density rule, density rule is placed on the knitted fabric, face toward slowly mobile density rule of light, make lines on the density rule and fabric through line parallel, can reflect clearly rhombus, the scale shown in the rhombus wedge angle upper and lower side is poor to be horizontal warp-wise per inch coil number.
The invention has the beneficial effects as follows: the method for a kind of calculating overfeeding based on measurement of density ruler of the present invention, can calculate overfeeding according to the coil number of density rule surveyingpin fabric, can science pass through the overfeeding adjustment and allow knitted fabric go out machine the time consistent in density, grammes per square metre consistent.
