Abstract
The invention provides a knitted fabric coil length rapid analysis method. The knitted fabric coil length rapid analysis method comprises the following steps of: 1) testing the weight of a knitted fabric sample specifically in such a manner that a length measuring tool is utilized to measure 20 cm respectively in the transverse direction and the longitudinal direction of the knitted fabric, the knitted fabric sample is placed in the standard atmosphere (with the temperature 20+/-2 DEG C, and the relative humidity 65%+/-5%), humidifying is carried out for 3-5 hours, and the weigh is weighed by a balance, is recorded as M and is accurate to 0.01 g; 2) testing the density of yarn used by the knitted fabric sample specifically in such a manner that 50 pieces of yarn is removed from the knitted fabric sample, a clamping device and a scale on a yarn twist instrument are utilized to test the stretched length thereof, the stretched length is recorded as L and is accurate to 0.1 cm, the weight of the 50 pieces of yarn is weighed by the balance, is recorded as m and is accurate to 0.01 g; and the density of the yarn is calculated by the yarn density formula: N=m*100000/50/L(tex); and 3) calculating the number of the knitted fabric coils specifically in such a manner that a fabric mirror (or a magnifier) is utilized to test the course (Pa) and wale (Pb) of the knitted fabric sample, and the number n of the knitted fabric coils is obtained by the formula n=16*Pa*Pb.
Description
Technical field
The present invention relates to a kind of loop length of knitted fabric and analyze method, belong to textile and analyze detection field.
Background technology
Loop length refers to weave in knitted fabric the loop length required for single coil, general in units of mm, it it is the main technologic parameters of knitting knitting fabric, not only determine knitted fabric density, the weight etc. of unit are, and laddering, extensibility, wearability, elasticity, strength and the anti-fluffing and anti-pilling of knitted fabric, hook silk etc. are had a great impact, it it is an important physical index of knitted fabric, also it is to determine product quality and the important parameter of surface density, and relates to the cost accounting of yarn-using amount and the economic benefit of enterprise.
Existing loop length of knitted fabric test mainly hands pulls tape measurement.A number of knitted fabric loop good for labelling is broken into yarn, pull the yarn two ends of labelling with hands and apply certain tension force, ensure that yarn stretches but do not extends, the length between 2, the yarn of labelling is measured with ruler, according to length and coil number, converse the length of a knitted fabric loop.This method is as a kind of method of testing of rough estimate loop length, and test result error is relatively big, and first tension force applying can not be quantitative, can only be according to situation of the stretching manual control of yarn, and subjectivity is too strong, and comparability is poor.
Summary of the invention
In place of overcoming the deficiencies in the prior art, the present invention provides a kind of loop length of knitted fabric method for rapidly testing, to improve the accuracy of test result, strengthens work efficiency, reduces labor intensity.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of loop length of knitted fabric method for rapidly testing, comprises the following steps:
1) knitted fabric example weight test；With survey long instrument measure 20cm along knitted fabric is horizontal and vertical respectively, by this knitted fabric sample in standard atmosphere (temperature 20 DEG C ± 2 DEG C, relative humidity 65% ± 5%) damping 3-5 hour, weigh with scale its weight, is designated as M, is accurate to 0.01g；
2) test of yarn linear density used by knitted fabric sample；Yarn linear density is defined as the long yarn of 1000m quality grams at the standard conditions, and unit is tex.50, yarn is pulled down in knitted fabric sample, the clamping device on yarn twist meter and scale is utilized to test its stretched length, it is designated as L, it is accurate to 0.1cm, weigh with scale the weight of 50 one threads, is designated as m, is accurate to 0.01g, yarn linear density N, N=m × 100000/50/L (tex) is calculated according to yarn linear density formula;
3) calculating of knitted fabric sample coil number；With horizontal stroke close (Pa) and vertical close (Pb) of fabric count glass (or magnifier) testing needle fabric sample respectively, horizontal stroke is close refers to the coil stringer number in line direction 5cm length interior loop, vertical close refer to the coil course count in file direction 5cm length interior loop, then knitted fabric sample coil number n=16 × Pa × Pb;
4) calculating of loop length of knitted fabric；
According to above-mentioned test result, loop length of knitted fabric l=M/N × 1000000/n (mm) can be obtained
The beneficial effects of the present invention is: method of testing is simple, operation quickly, test result accurately and reliably, have universal.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
A kind of loop length of knitted fabric method for rapidly testing described in the embodiment of the present invention, as a example by latitude jersey:
1) latitude jersey example weight test；With survey long instrument measure 20cm along knitted fabric is horizontal and vertical respectively, by this knitted fabric sample in standard atmosphere (temperature 20 DEG C ± 2 DEG C, relative humidity 65% ± 5%) damping 3-5 hour, its weight that weighs with scale is 7.2 g；
2) test of yarn linear density used by latitude jersey sample；50, yarn is pulled down in knitted fabric sample, the clamping device on yarn twist meter and scale is utilized to test its stretched length for 24.2cm, the weight of 50 one threads of weighing with scale is 0.24g, yarn linear density N, N=0.24 × 100000/50/24.2=19.8 (tex) is calculated according to yarn linear density formula;
3) calculating of knitted fabric sample coil number；With the horizontal stroke close (Pa) of fabric count glass (or magnifier) testing needle fabric sample respectively be 80 stringer/5 cm and vertical close (Pb) is 122 line/5 cm, then latitude jersey sample coil number n=16 × 80 × 122=156160;
4) calculating of latitude jersey loop length；
According to above-mentioned test result, latitude jersey loop length l=7.2/19.8 × 1000000/156160=2.3 (mm) can be obtained.
