Description
技术领域 technical field
本发明涉及一种采用电脑配色系统预测锦棉织物同色性配方的方法。The invention relates to a method for predicting the same-color formula of nylon-cotton fabrics by using a computer color matching system.
背景技术 Background technique
随着我国纺织产业的升级，为了改善国内印染业的生产条件，便于国际贸易的交流，印染企业相继引进测色配色仪器。与人工配色相比，电脑配色具有节省染化料用量，缩短生产周期，提高生产效率的优点。在实际应用过程中，由于对测配色仪器及配色理论的不完全了解，配色软件中的配色功能并未得到充分的利用。With the upgrading of my country's textile industry, in order to improve the production conditions of the domestic printing and dyeing industry and facilitate international trade exchanges, printing and dyeing enterprises have successively introduced color measuring and matching instruments. Compared with manual color matching, computer color matching has the advantages of saving the amount of dyes and chemicals, shortening the production cycle and improving production efficiency. In the actual application process, due to the incomplete understanding of the color matching instrument and color matching theory, the color matching function in the color matching software has not been fully utilized.
同色性是指将两种纤维染成相近的色相或色调，而且表观色深或颜色浓淡相近，颜色鲜艳度也接近。同色染色是双组分纤维纺织品采用最多的一种染色方法。双组分织物的同色性染色是当前染色技术中的一个难题。产品重现性差，仿色困难，回修率高，引起劳动力成本与染化料、能源的浪费。平目前，我国的双组分纤维织物的染整加工多数仍停留在经验加工水上，染色产品质量受诸多主观与客观因素的影响，急需建立多组分纤维特别是常规双组分纤维织物的同色性测配色方法，以减少无谓的劳动力、染化料与能源的浪费，提高生产效率。The same color means that two fibers are dyed into similar hue or tone, and the apparent color depth or color shade is similar, and the color brightness is also close. Same-color dyeing is the most widely used dyeing method for bicomponent fiber textiles. The homochromatic dyeing of two-component fabrics is a difficult problem in the current dyeing technology. Product reproducibility is poor, color dithering is difficult, and the repair rate is high, causing labor costs, dyeing materials, and energy waste. At present, most of the dyeing and finishing of bicomponent fiber fabrics in my country still stays on the level of empirical processing, and the quality of dyed products is affected by many subjective and objective factors. The color matching method can be used to reduce unnecessary labor, waste of dyeing materials and energy, and improve production efficiency.
对于锦棉织物同色染色，一般是将锦纶和棉两种纤维染色，通过配色获得两种纤维各自的配方。由于配色过程中，未考虑染棉的活性染料对锦纶的沾色和染锦纶的酸性染料对棉的沾色，需要有经验的技术人员对配方进行再调整才能得到同色性较好的配方。For the same color dyeing of nylon and cotton fabrics, generally two fibers of nylon and cotton are dyed, and the respective formulas of the two fibers are obtained through color matching. In the process of color matching, the staining of nylon by reactive dyes dyed cotton and the staining of cotton by acid dyes dyed nylon are not taken into account. Experienced technicians need to readjust the formula to obtain a formula with better color matching.
发明内容 Contents of the invention
本发明的目的在于提供一种采用电脑配色系统预测锦棉织物同色性配方的方法，本发明充分考虑锦棉织物染色过程中，染棉的活性染料对锦纶的沾色和染锦纶的酸性染料对棉的沾色，获得的配方对锦棉织物的同色性较好。The object of the present invention is to provide a kind of method that adopts computer color matching system to predict the same color formula of nylon-cotton fabric, the present invention fully considers in the dyeing process of nylon-cotton fabric, the staining of the reactive dye of dyed cotton to nylon and the effect of the acid dye of dyed nylon on nylon-cotton fabric. For staining of cotton, the obtained formula has better same-color property to nylon-cotton fabric.
目前，测配色仪器已广泛应用于各类单组分纤维、织物和皮革等的配色打样。电脑测配色应用首先需要建立基础数据库，一般将各种染料浓度由浅到深分成几个浓度档次依次对织物染色，然后测试色样输入电脑，根据来样由基础数据计算出配方进行染色，最后进行配方修正直到色样符合客户要求。At present, color matching instruments have been widely used in color matching proofing of various single-component fibers, fabrics and leathers. The application of computer color matching first needs to establish a basic database. Generally, the concentration of various dyes is divided into several concentration levels from light to dark to dye the fabric in sequence, and then the test color sample is input into the computer, and the formula is calculated from the basic data according to the sample. Formula correction until the color sample meets customer requirements.
根据电脑配色的基本原理，在一定染色浓度范围内，纤维上染料上染量与染浴中使用的染料浓度呈一定的线性关系。According to the basic principle of computer color matching, within a certain range of dyeing concentration, the amount of dye on the fiber has a certain linear relationship with the concentration of dye used in the dye bath.
K/S＝kc （1）K/S＝kc （1）
其中K表示被测织物的吸收系数；S表示被测织物的散射系数（通常，不需要K、S的具体数值，仅计算K/S的比值，因此称作“K/S”值，表示被测织物的表观色深度）；c表示被测织物上的染料浓度，k表示被测织物上染单位浓度的染料所获得的K/S值。Among them, K represents the absorption coefficient of the tested fabric; S represents the scattering coefficient of the measured fabric (usually, the specific values of K and S are not required, and only the ratio of K/S is calculated, so it is called "K/S" value, which means the value of the tested fabric The apparent color depth of the tested fabric); c indicates the dye concentration on the tested fabric, and k indicates the K/S value obtained by dyeing the unit concentration of the tested fabric.
同理，对于多个染料配色(K/S)m关系式为：Similarly, for multiple dye color matching (K/S) m relational formula is:
式中：(K/S)m表示目标色织物的表观色深；In the formula: (K/S) m represents the apparent color depth of the target colored fabric;
(K/S)0表示空白织物的表观色深；(K/S) 0 represents the apparent color depth of the blank fabric;
ki表示空白织物上各染料单位浓度的K/S值；k i represents the K/S value of each dye unit concentration on the blank fabric;
ci表示各染料的浓度。c i represent the concentration of each dye.
(K/S)m和(K/S)0可以由测色系统测试得到,而ki必须通过制作基础数据曲线得到，确定了一个染料的基础数据曲线，也就确定了该染料在一定染色浓度范围内单位浓度的K/S值（即ki）。根据ki可以计算出配方中各个染料的用量。(K/S) m and (K/S) 0 can be obtained by the color measurement system, and ki must be obtained by making the basic data curve, and the basic data curve of a dye is determined, which also determines the color of the dye in a certain dyeing The K/S value of unit concentration within the concentration range (ie k i ). According to ki, the dosage of each dye in the formula can be calculated.
建立酸性染料对锦纶织物的电脑测配色基础数据库和活性染料对棉织物的电脑测配色基础数据库，调用相应的基础数据库对锦纶和棉进行配色、染色和修色，可以分别获得与目标色一致的酸性染料染色配方和活性染料染色配方。但在染色过程中，酸性染料会对棉沾色，而活性染料会对锦纶沾色，所以获得的染色配方对锦棉织物染色后，双组分织物的同色性会存在一定的问题。Establish the basic database of computer color matching of acid dyes on nylon fabrics and the basic database of computer color matching of reactive dyes on cotton fabrics, and call the corresponding basic databases for color matching, dyeing and color correction of nylon and cotton, and can obtain the same color as the target color respectively. Acid dye dyeing formula and reactive dye dyeing formula. But in the dyeing process, acid dyes can stain cotton, and reactive dyes can stain nylon, so after the obtained dyeing formula dyes nylon and cotton fabrics, there will be certain problems in the same color of the two-component fabrics.
以活性/酸性染料染棉/锦纶织物而言，棉织物上的表观色深值由三部分组成，即空白棉织物的表观色深值、活性染料上染棉织物的表观色深值和酸性染料对棉织物沾色的表观色深值。而锦纶织物上的表观色深值也由三部分组成，即空白锦纶织物的表观色深值、酸性染料上染涤纶织物的表观色深值和活性染料对涤纶织物沾色的表观色深值，关系式如下：For cotton/nylon fabrics dyed with reactive/acid dyes, the apparent color depth value on cotton fabrics consists of three parts, namely, the apparent color depth value of blank cotton fabrics and the apparent color depth value of cotton fabrics dyed with reactive dyes The apparent color depth value of cotton fabric stained with acid dyes. The apparent color depth value on nylon fabric is also composed of three parts, that is, the apparent color depth value of blank nylon fabric, the apparent color depth value of polyester fabric dyed with acid dye, and the apparent color depth value of polyester fabric stained by reactive dye. Color depth value, the relationship is as follows:
(K/S)棉＝（K/S)棉0+（K/S）活性染料+（K/S）酸性染料沾色 （3）(K/S) cotton = (K/S) cotton 0 + (K/S) reactive dye + (K/S) acid dye staining (3)
(K/S)锦纶=（K/S)锦纶0+（K/S）酸性染料+（K/S）活性染料沾色 （4）(K/S) nylon = (K/S) nylon 0 + (K/S) acid dye + (K/S) reactive dye staining (4)
要使锦棉双组份织物在染色后获得同一色泽，则To make nylon-cotton two-component fabrics obtain the same color after dyeing, then
（K/S)棉＝（K/S)锦纶 （5）(K/S) Cotton = (K/S) Nylon (5)
式中：In the formula:
(K/S)棉、(K/S)锦纶分别表示目标色样的表观色深；(K/S) Cotton and (K/S) Nylon respectively indicate the apparent color depth of the target color sample;
（K/S)棉0、（K/S)锦纶0分别表示空白棉织物和锦纶织物的表观色深值；(K/S) cotton 0 , (K/S) nylon 0 represent the apparent color depth value of blank cotton fabric and nylon fabric respectively;
（K/S）活性染料表示活性染料上染棉织物的表观色深值；(K/S) Reactive dyes represent the apparent color depth of cotton fabrics dyed with reactive dyes;
（K/S）酸性染料表示酸性染料上染锦纶织物的表观色深值；(K/S) acid dye indicates the apparent color depth of nylon fabric dyed with acid dye;
（K/S）酸性染料沾色表示酸性染料对棉织物沾色的表观色深值；(K/S) Acid dye staining indicates the apparent color depth value of acid dye staining on cotton fabric;
（K/S）活性染料沾色表示活性染料对锦纶织物沾色的表观色深值。(K/S) Reactive dye staining indicates the apparent color depth value of reactive dye staining on nylon fabric.
经过实验发现，酸性染料对棉的沾色甚微，但是活性染料对锦纶的沾色比较明显，即（K/S）活性染料>>（K/S）酸性染料沾色而（K/S）酸性染料>（K/S）活性染料沾色。After experiments, it was found that the staining of acid dyes on cotton was slight, but the staining of nylon by reactive dyes was more obvious, that is, (K/S) reactive dyes >> (K/S) acid dyes and (K/S) Acid dye > (K/S) reactive dye staining .
则公式（3）可简化为：Then formula (3) can be simplified as:
(K/S)棉＝（K/S)棉0+（K/S）活性染料（6）(K/S) cotton = (K/S) cotton 0 + (K/S) reactive dye (6)
公式（5）可转化为：Formula (5) can be transformed into:
（K/S)棉0+（K/S）活性染料＝（K/S)锦纶0+（K/S）酸性染料+（K/S）活性染料沾色（7）(K/S) cotton 0 + (K/S) reactive dye = (K/S) nylon 0 + (K/S) acid dye + (K/S) reactive dye staining (7)
如果将(K/S)活性染料沾色设为目标色样，采用酸性染料对锦纶织物的电脑测配色基础数据库进行配色和修色，可以获得一组酸性染料配方，即这组酸性染料染色配方对锦纶织物的染色效果与活性染料对锦纶织物的沾色效果相同。If (K/S) reactive dye staining is set as the target color sample, and acid dyes are used to match and repair the computer-based color matching database of nylon fabrics, a set of acid dye formulas can be obtained, that is, this set of acid dye dyeing formulas The dyeing effect on nylon fabric is the same as that of reactive dyes on nylon fabric.
为了达到上述目的，本发明的技术方案是：In order to achieve the above object, technical scheme of the present invention is:

8）根据目标色，采用基础数据库二对空白的混合织物进行电脑配色，根据配方进行打样，将打样所得纯锦纶织物色样输入电脑，由电脑给出修色配方，根据修色配方继续打样；8) According to the target color, use the basic database 2 to carry out computer color matching on the blank mixed fabric, and carry out proofing according to the formula, input the color sample of pure nylon fabric obtained from the proofing into the computer, and the computer will give the color correction formula, and continue proofing according to the color correction formula;
9)重复步骤8），直到纯锦纶织物色样与目标色的色差满足要求，获得酸性染料染色配方二，将酸性染料染色配方二减去酸性染料染色配方一获得酸性染料染色配方三；9) Repeat step 8) until the color difference between the pure nylon fabric color sample and the target color meets the requirements, and obtain the acid dye dyeing formula 2, and subtract the acid dye dyeing formula 1 from the acid dye dyeing formula 2 to obtain the acid dye dyeing formula 3;
