Abstract

Jumputan batik is batik made by tie and dyeing techniques with the desired motif and color.There are two techniques of making jumputan batik, the first is with the tie technique, andthe second is the sewing technique, the threads used to tie the fabric should be made of thickand strong threads, so that they can prevent dyes from entering the fabric, such as plastic /synthetic threads. jeans floss, or shoe thread. The method used in this community serviceactivity is counseling (socialization) and the practice of making batik which is carried outon students who are accompanied by the students' parents at Qurrata A'yun CimahiKindergarten. This activity is not only aimed at training students' creativity, which is shownby the creation of the tie and coloring of each batik they produce and is also expected tomotivate parents of students to gain new knowledge and be able to produce products thathave high use value and selling value, so that they can be an opportunity to improve theeconomy.

Abstract

Polyester fabrics are the most popular clothing material in the textile product manufacturing process and are widely used. Small floral motifs, line or small dots that are sharp and bright (more than one color) on the basis of contrasting or dark colors usually obtained by discharge printing or resist printing, because it is not easy to do by direct printing in a large amount of production. In printing alkali discharge, polyester fabrics are used dispersion dyes that can be damaged by alkali (azo type) as the base color. Color motifs are used dispersion dyes that are resistant to alkalis (anthraquinone type) which do not have ester groups in their chromophore. The purpose of this study was to determine the extent to the influence of the concentration of using sodium carbonate 100, 150, 200, 250 g/kg paste as etching agent and fixation time 4,6,8 minutes temperature 180 °C, then testing the degree of fabric white, color difference, fabric tensile strength and color fastness against washing and rubbing. The optimum conditions were achieved in sodium carbonate 200 g/kg paste, temperature 180 °C for 6 minutes, white degree of fabric Δ K/S 0.01684, color difference value Δ E= 2,81, fabric tensile strength of 17,40 kg towards warp 18,05 kg towards the feed, fastness to washing 4-5, color fastness to wet rubbing and dry rubbing 4-5. Keywords : sodium carbonate, discharge printing, azo, anthraquinone, polyester

Abstract

The process of bleach washing on denim fabrics produces a paler or lighter shabby effect. The shabby effect is produced by using an oxidizing agent. The application of sodium hypochlorite can cause a decrease in color aging of denim fabrics and high tensile strength. The pH condition also affects the occurrence of oxycellulose damage which will affect the final result. Inappropriate pH will cause a very high oxidation process and produce a less shabby effect and can cause a decrease in tensile strength. Therefore, the concentration of NaOCl and pH must be adjusted properly so that optimal results are obtained. The purpose of this study was to determine the effect of optimum concentration of sodium hypochorite (NaOCl) and pH on the physical properties of denim fabric. After the process of bleach washing process experiment was carried out, a test was carried out based on two-factor Anova statistical data and the optimum visual test fabric results were obtained at a NaOCl concentration of 2 g/L using alkaline pH (10-11). The test values were obtained as follows: color fastness to rubbing are 3-4 for dry, 2-3 for wet, tensile strength 67.4 kg in warp direction, 43.1 in weft direction, fabric stiffness in warp direction 430.48, weft direction 344.54. The factory standard for a tensile strength of 65 kg warp direction, 40 kg weft direction, color fastness to rubbing 3 for dry rubbing and 2 for wet rubbing. Keywords: bleach washing, denim, sodium hypochlorite, oxycellulose, color fastnes

Abstract

The printing with pigment dyes on 100% polyester fabric is one of the materials that can be used to make clothes. Clothing products made with the printing technique must have a good color fastness. In printing with pigment dyes must be mixed with a binder. These binder have different solid content (% glucose). Therefore, the selection of the right binder is very important t produce quality fabrics with good color fastness. The purpose of this study was to determine the value of color fastness to washing and rubbing and the value of color differences in the printing process with pigment dyes on 100% polyester fabrics and to determine which binder had the best results. The method of this study used is an experiment with a lab scale. After experimenting with the printing process using the Binder FS-462 and Sky Binder 235, a test was conducted which stated that Binder FS-462 was the binder that had the best results. The test values ​​were obtained as follows, color fastness to washing on dark colors 4-5 for staining scale and 4 for grey scale, color fastnes to rubbing on dark colors 4 for dry and 2-3 for wet. The factory standard is for color fastness to washing 3 for staining scale and 4 for grey scale, color fastness to rubbing 3-4 for dry and 2-3 for wet, and color difference values ​​>1.

Abstract

Simultaneous processes are processes that are implemented simultaneously where the process and substances used do not interfere with each other, the purpose of each process of preparation for refinement is implemented to remove starch on the warp threads in the form of natural impurities, external impurities and natural pigments in a short time and satisfactory result. The purpose of this research is to improve the quality of the results of the scouring process, and bleaching simultaneously in the pad-batch system. This research method was carried out by varying the concentration of H2O2: 20 g/l, 30 ml/l and 40 g/l using a 70% squeeze effect and a batching time of 12 hours. After the experiments were carried out, tests were implemented on starch content, absorption capacity - capillary test, degree of whiteness, tear strength test by tongue method and aging test (ΔE). From the experimental and test results, the optimum conditions showed that the higher the concentration of H2O2 up to a concentration of 40g/l with the same batching time for 12 hours was obtained at a concentration of H2O2 of 30 g/l where in these conditions starch could be removed from the material properly. Absorption power in 1 minute absorbs color as high as 4 cm. The white degree test results are 61.66%. The tear strength in the warp direction was 9.675 N and the tear strength in the weft direction was 7.475 N and the (ΔE) color difference value of L* (Lightness) or the brightness level was 73.74 for light colors; medium color 62.68; and dark color 20.49
