    DETAILED DESCRIPTION OF THE EMBODIMENTS

    [0058] In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in combination with embodiments. It should be understood that, the embodiments described herein are only intended to illustrate but not to limit the present invention.

    [0059] As shown in FIG. 1, a method for estimating natural environment impact of textile fabric production according to the present invention comprises the following steps. [0060] Step 1: inputting composition of a textile fabric and a name of region where one or more steps of the textile fabric production are implemented, wherein the textile fabric may be a textile fabric made of a single raw material, a textile fabric mixed of a plurality of raw materials or other textile fabrics, and the region where the one or more steps of the textile fabric production are implemented may be a country or district where the one or more steps of the textile fabric production are implemented, and the ecological impact generated by the textile fabric production in different countries or districts may be obviously different due to different production technical levels and environmental protection requirements of various countries or districts. [0061] Step 2: calling corresponding data from a database according to the input composition and the name of region. The data in the database may come from industrial, environmental and human statistical data of various districts/countries; reports from international organizations (for example, WHO, UN, WTO, OECD), such as Global Greenhouse Gas Emissions Data issued by a USA environmental protection organization; reports from non-governmental agencies (for example, environmental protection and right agencies), such as Flawed Fabrics The abuse of girls and women workers in the South Indian textile industry, published by the Centre for Research on Multinational Corporations and the Indian Committee of the Netherlands; academic reports/articles, such as Animal Ethics and Welfare in the Fashion and Lifestyle Industries, published by Green Fashion on Jan. 23, 2016, pp 49-122; reports (child labor, animal treatment, or the like), such as an adverse behavior toward sheep in a wool clipping process reported by nbcnews on Jul. 8, 2004; related data of business entities, or the like. The collected data is formed into a standard-order numeric matrix. The standard-order numeric matrix which may be used in the present invention may be obtained in various ways known in the art. In one example, the collected data is sorted in an increasing order to form a standard-order numeric matrix (for example, a numeric matrix from 0 to 100) corresponding to the numerical order of the collected data; the data may be standardized using the standard-order numeric matrix; that is, according to the input raw material and the name of country or region, corresponding standard data may be found from the standard-order numeric matrix, for example, corresponding ordinal values in the standard-order numeric matrix. For example, when the input raw material and name of country or district are cotton and China, in order to obtain the standard data corresponding to greenhouse gas in a raw material production step, if the system according to the present invention finds the ranking position of the standard data in the matrix to be 5th from the database, the standard data is 5. The inventor collected and calculated data on greenhouse gas emission, wastewater, water, energy consumption, chemical consumption and solid waste in the processes of cotton planting, picking, spinning, weaving, bleaching, dyeing and finishing in countries, such as China, USA, India, Pakistan, or the like, so as to obtain all data on each factor of different steps in different countries, thereby establishing the database. The database may be updated irregularly or regularly via a network server; when the corresponding data is not called from the database, an average of all the regions may be adopted to replace the missing data. [0062] Step 3: obtaining a score of the natural environment impact of the one or more steps of the textile fabric production according to a predetermined first operational rule and the data called from the database. The first operational rule comprises a formula (1) EI.sub.i=(GW+WW+WC+EC+CM+SW), wherein EI.sub.i denotes the score of the natural environment impact of the ith step, GW denotes a greenhouse gas score item, WW denotes a wastewater score item, WC denotes a water score item, EC denotes an energy consumption score item, CM denotes a chemical-consumption score item, and SW denotes a solid waste score item. Preferably, a set of predetermined weighted weights (.sub.n, n=1,2,3,4,5,6) is selected to be applied to each score item in the formula (1) of the first operational rule respectively, so as to optimize the score of the natural environment impact of each step in the production.

    [0063] Preferably, the method for estimating the natural environment impact of the textile fabric production according to the present invention further comprises step 4, that is, determining a comprehensive score of the natural environment impact of the textile fabric production from the obtained scores of the natural environment impact of the plural steps according to a predetermined second operational rule. The second operational rule comprises a formula (2) EI.sub.0=.sub.i=1.sup.7EI.sub.i, wherein EI.sub.0 denotes the comprehensive score of the natural environment impact, EI.sub.1 denotes a raw material production step score item, EI.sub.2 denotes a fiber production step score item, EI.sub.3 denotes a yarn production step score item, EI.sub.4 denotes a fabric production step score item, EI.sub.5 denotes a dyeing step score item, EI.sub.6 denotes a finishing step score item, and EI.sub.7 denotes a recycling step score item. Preferably, a set of predetermined weights (.sub.n, n=1,2,3,4,5,6,7) is selected to be applied to each score item in the formula (2) of the second operational rule respectively, so as to optimize the comprehensive score of the natural environment impact. Preferably, the obtained comprehensive score of natural environmental impact is converted into a standard score, for example, by standardizing the maximum and minimum values of the obtained data among countries.

    [0064] The method for estimating the ecological impact of the textile fabric production according to the present invention not only may comprise the method for estimating the natural environment impact, but also further comprises estimating a human society impact and an animal right impact. Herein, estimating the human society impact in the present invention may comprise: calling a corresponding report in the database according to the input name of region, and outputting a title of the corresponding report as an estimation result. Estimating the animal right impact in the present invention may comprise: calling a corresponding report in the database according to the input name of region, and outputting a title of the corresponding report as an estimation result. Since various factors in the human society impact and the animal right impact are difficult to calculate quantitatively and are unable to be calculated directly with the operational rule, thus, the present invention predetermine appropriate weights according to the importance of each factor in the human society impact and the animal right impact, such that an assessment result of the factor with a high weight is displayed in the above-mentioned output report preferentially, and thus, a user may conveniently perform an assessment more efficiently. Herein, the estimation result of the human society impact may comprise employee treatment, career development and training, medical security, working environment, occupational safety, community services and transparency; the estimation result of the animal right impact may comprise animal experiments, animal abuse and other inhuman animal treatment behaviors.

    [0065] It should be noted that, in the art, it is difficult to select appropriate weights, the importance of different affecting factors (i.e., the above-mentioned score items) is required to be considered, and by applying appropriate weights to different affecting factors, an assessment result of the ecological impact which is more objective and accurate is obtained. For the natural environment impact, the weight is used as a weighted average factor in the formulas of the first and second operational rules to calculate a weighted average. For the human society impact and the animal right impact, the weight represents the importance of each factor in the output report, and the factor with a high weight is displayed preferentially. In the present invention, for each factor, the selected weight ranges from 0.1 to 2.0, wherein 0.1 represents the factor which is least important, and 2.0 represents the factor which is most important, that is, a larger value represents a higher importance. In the present invention, the preferred range of the weight of each factor is obtained with a large number of experiments and calculations.
