Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Such as the flow chart that Fig. 1 is fabric UPF measuring method of the present invention.Opening in the present invention The when of beginning, it is necessary first to set up the database of existing yarn fabric.In step S1, by existing measurement Technology or the experiment carried out, by ultraviolet corresponding to the parameters of each sample and each sample Protecting factor recorded in database, as the matching basis of subsequent step.The parameter of these samples is permissible Following parameter selects: tight ness rating, thickness, weight, yarn count, fiber type, lightness, Levelness, gas permeability, stitch density, tight ness rating, washing cycle, yarn tension, yarn strength, yarn Line combination, vapor permeability and colour are poor；Colour difference includes that red green difference and blue yellow are poor.

Wherein, tight ness rating K is defined as follows:

$K=\frac{\sqrt{\mathrm{tex}}}{l};$

Wherein, tex is thread density, and in units of gram every kilometer, l is loop length, with millimeter as list Position.

Thickness refer to sample in the distance being perpendicular on light direction, in units of millimeter；Weight refers to sample The weight of product unit are, in units of gram every square metre；Yarn count refers to the density of yarn, with NE as list Position；Fiber type be sample material composition, selected the most in the present invention 100% combed cotton (CH), 100% combed cotton ESTex(MCG), 100% combed cotton Supima cotton (F) and 100% combing Supima Cotton ESTex(MF_LT), and substitute respectively by numeral 0,1,2,3 in follow-up fit procedure；Bright Brightness and colour difference all use the detection scheme in Standard Colors mensuration.

The most in step s 2, select the parameter required for several these matchings, intend actual carrying out Several above-mentioned parameters can be selected the when of conjunction to be fitted, in order to simulate selected parameter and ultraviolet Relation between protecting factor.

Then in step S3, the relation between matching parameter and ultraviolet protection coefficient out is substituted into new plan Fixed scheme, thus draw the ultraviolet protection coefficient in new departure.The process of whole measuring and calculating be not required to by The production of the new departure related to out, thus improves the efficiency of production.

In the present invention, step S2 have employed binary tree approximating method (Binary Space Partitioning, BSP) obtain the relation between selected parameter and UPF.The most such as Under:

S21, set up the addressing space (Search Space, SS) of a N-dimensional, corresponding selected N number of Parameter, with X={x1, x2 ... xn} is representing, with y=f(X) represent ultraviolet protection coefficient；So corresponding The parameter of each sample can be expressed as Xi={xi1, xi2 ... xin};The ultraviolet that each product is corresponding Protecting factor is yi=f (Xi).

S22, when the ultraviolet protection coefficient of all of sample parameters and correspondence is saved in database, It is formed for an original high-dimensional responsive plane, i.e. BSP tree.Selected a region Ri, Ri in SS Belong to Xi, then yi corresponding for Xi is stored in Ri.This Ri region is a higher-dimension in SS Degree cube.

S23, owing to BSP tree can be affected by the storage sequence of data, such as X1, the storage of X2, X3 is suitable Sequence and meeting and X3, the storage sequence of X1, X2 produces different results, according to this principle, sets up 3 Data tree: TreeA, TreeB, TreeC；Represent all data, the half of total evidence respectively and arrange at random Row, a remaining half data.

If S24 we to set up one about between parameter Xe to be asked with corresponding ultraviolet protection coefficient ye Relation, then find respectively in 3 data trees correspondence the region corresponding to Xe: Ra, Rb, Rc.So Rear calculating is the distance of Xe and Xi, da, db and dc in Ra, Rb, Rc；

Then the ye corresponding to Xe is:

Ye=wa × yia+wb × yib+wc × yic

Wherein:

$\mathrm{wa}=\frac{\mathrm{db}+\mathrm{dc}}{2(\mathrm{da}+\mathrm{db}+\mathrm{dc})}$

$\mathrm{wb}=\frac{\mathrm{da}+\mathrm{dc}}{2(\mathrm{da}+\mathrm{db}+\mathrm{dc})}$

$\mathrm{wc}=\frac{\mathrm{db}+\mathrm{da}}{2(\mathrm{da}+\mathrm{db}+\mathrm{dc})}$

Yia, yib, yic are the value of the yi stored in Ra, Rb and Rc the most respectively.

First embodiment

Below using weight, thickness, stitch density, tight ness rating and washing cycle as selected parameter, each Supplemental characteristic corresponding to sample is as follows:

UPF=-26.215+0.095 × weight+5.010 × thickness+0.005 × stitch density + 0.365 × washing cycle of+7.681 × tight ness rating.

Understanding through the actual test of three samples and the contrast of the Fitting Calculation, both numerical value is sufficiently close to, In the range of measure error, it is believed that the ultraviolet protection coefficient that the Fitting Calculation obtains and directly test Numerical value is equal.

Second embodiment

Below using yarn tension, yarn strength, yarn combination, vapor permeability as parameter, each Supplemental characteristic corresponding to sample is as follows:

Table 2

These parameters are the parameter related in matching, utilize to enter with the BSP approximating method in embodiment 1 Row matching, can obtain following parameters relationship:

3rd embodiment

, weight, levelness poor using lightness, red green yellow poor, blue and gas permeability are as parameter below, Supplemental characteristic corresponding to each sample is as follows:

Table 3

These parameters are the parameter related in matching, utilize aforementioned in step S21 to step S24 BSP approximating method is fitted, and can obtain following parameters relationship:

Poor+0.923 × indigo plant of UPF=-184.293-2.934 × lightness+0.156 red green Yellow poor+1.444 × weight+217.171 × thickness+1.693 × levelness+50.47 × gas permeability.

Understanding through the actual test of three samples and the contrast of the Fitting Calculation, both numerical value is sufficiently close to, In the range of measure error, it is believed that the ultraviolet protection coefficient that the Fitting Calculation obtains and directly test Numerical value is equal.

4th embodiment

Given below one group about tight ness rating, thickness, weight, yarn count, fiber type, lightness, red The data of green yellow poor, blue difference.

Table 4

The present embodiment is not required to carry out such as the matching of 3 embodiments above from newly, it is only necessary to according to reality Execute 3 formula that matching obtained by example 1～3 obtains, by BSP approximating method above, select phase The parameter closed, i.e. can directly obtain the result of calculation of matching.Thus reduce the complexity of the Fitting Calculation.

Visible, as long as when in the face of new parametric scheme, the parameter that can first detect correspondence has been joined With cross other parameter fitting process, if so, this can utilize existing fitting formula, by BSP side Method, directly obtains the result of the Fitting Calculation, it is not necessary to carry out the process from new fitting formula.

The fabric ultraviolet protection coefficient being illustrated in figure 3 the present invention measures the structural representation of system, this survey Amount system includes database 100, for recording parameter and the UPF of existing fabric；With data The matching assembly 200 that storehouse 100 connects, for selecting the parameter in database 100, simulates the ginseng of selection Number and the relation of UPF；The computation module 300 being connected with matching device 200, is used for inputting newly Parameter values, obtain fabric UPF.

After establishing such as the measurement system of Fig. 3, fabric research staff has only in the face of as shown in Figure 4 Computation module 300 can realize the input of parameters in new fabric scheme, it becomes possible to obtains under new parameter Fabric ultraviolet protection coefficient, whole process is without producing the scheme related to, thus shortens The research and development time.

These are only the specific embodiment of the invention, it is impossible to limit the scope of the present invention, this technology with this The impartial change that those skilled in the art in field are made according to this creation, and those skilled in that art Known to change, all should still belong to the scope that the present invention contains.
