Cold-pad-batch technique of silk dyeing fabric with two natural dyes (Laccifer lacca Kerr. And Garcinia dulcis (Roxb.) Kurz bark) using pre-mordant are performed using 3 different mordants namely, alum, tartaric acid and ferrous sulfate. The study showed that color intensity (K/S) slightly increased when the batching time increased from 1 to 24 hours. Dyed silk fabrics have different color shades depending on the types of mordant applied. Ferrous sulfate and alum was found to be the best mordants for improvements of color depth. Various fastness properties (wash, crock and light) of the dyed silk fabrics have also been investigated.

Kepentingan meningkat untuk pewarna semulajadi bermula beberapa tahun lalu tetapi di pihak pengguna, manfaat tersebut hanya mula dirasai. Pewarna asli dianggap sebagai pewarna mampan dan mesra alam; mereka boleh menghasilkan warna yang berbeza warna dan mempunyai ketahanan luntur yang lebih rendah daripada pewarna sintetik. Oleh itu, kertas kerja ini dikaji pada sifat kubu daripada pewarna yang diekstrak daripada kacang belalang dan buah-buahan asam buah.Warna-warna ini dipetik menggunakan kaedah berair dan pelarut dan telah digunakan di dataran terluntur ditenun kapas dan sutera kain.Yang digunakan bagi pedas meningkatkan penembusan warna (pewarna) dan sampel dicelup telah tertakluk kepada ujian kubu (membasuh, menggosok, peluh & ujian cahaya). Perbandingan analisis kepada tahap pewarnaan telah direkodkan dan ujian kubu baik daripada analisis membuktikan bahawa; warna boleh digunakan sebagai pewarna pada kapas dan sutera kain.   An interest for natural dyes increased several years ago but on the part of the consumers, the benefits are just beginning to be felt. Natural dyes are considered as sustainable and ecofriendly dyes; they can produce different shades of colours and have lower colour fastness than synthetic dyes. Therefore, this paper researched on the fastness properties of colorant extracted from locust beans and tamarind fruits pods. The colours were extracted using aqueous and solvent methods and were applied on bleached plain weaved cotton and silk fabrics. The use of mordant increased the penetration of the colours (dyes) and the dyed samples were subjected to fastness test (washing, rubbing, perspiration & light test). Comparative analyses on the degree of staining were recorded and good fastness test from the analysis proved that; the colours can be used as dyes on cotton and silk fabrics.

The use of non-toxic and eco-friendly natural dyes on textiles has become a matter of significant importance because of the increased environmental awareness in order to avoid some synthetic dyes. Synthetic dyes are hazardous and carcinogenic and also release vast amount of pollutant in the environment during their manufacture and application, thus revival of natural dyeing techniques as one of the alternative is being emphasized for this purpose. Most effective ways for reducing environmental pollution is the replacement of polluting materials and chemicals by eco-friendly natural materials. Many natural resources which are being wasted indiscriminately or thrown away as a waste product contain useful dyes and pigments. In the present study, natural dye extracted from the waste leaves of Terminalia Catappa (tropical almond) and its application on silk fabrics pretreated with eco-friendly and non-eco-friendly mordants have been carried out successfully. Different shades with excellent to good fastness properties have been obtained.

A new source of natural anthocyanins dyes, from Liriope platyphylla fruit, is proposed. This paper analyzes the dye extracts, the primary color components of the extracts, the color features of the extracts under different pH conditions, and their application in silk dyeing. The research shows that, nine anthocyanins are found in  L. platyphylla fruits by analyzing the results of the HPLC/DAD, MS, and MS/MS spectra. The five major anthocyanins related to delphinidin, petunidin, and malvidin derivatives take up 91.72% of total anthocyanin contents. The color of the solution is red under acidic condition (pH < 3.0) and stays in yellow under alkaline condition with pH values above 7.0. The dye extracts applied to silk fabric with mordant free dyeing show different color under different pH conditions, changing between purple, blue, green, and yellow. However, the dyed colors is light and the dyeing rate is low. Metal mordant such as Sn in chelation enhances the dye depth and improves the fastness of the dyed silk fabrics, especially in silk fabrics dyed by premordanting and metamordanting.

Natural dyes come from plenty of sources including plants, animals, insects or microorganisms. At present, natural dyes are highly demanded in textile application. In this study, brown seaweed (Sargassum spinosum) extracts were utilized for silk coloration with the use of metallic salts mordants (Iron II Sulphate and Aluminium Sulphate) and biomordants (cinnamon and chitosan). Dyeing was performed with pre-mordanting and simultaneous mordanting methods. The dyed fabrics were analyzed in terms of color fastness properties to washing, perspiration, rubbing and light. The results revealed that seaweed dyes with cinnamon mordant gave darker shades and higher absorbency towards silk which is comparable to iron mordant. The approach of using biomordant is parallel to the sustainability demand of natural dyes in textile application.

Two lichens species (ParmotremapraesorediosumandHeterodermialeucomelos)were assessed for dye production using boiling water method (BWM) and ammonia fermentation method (AFM). The dyes were applied on silk fabric. Three types of mordant were used i.e. alum, iron and vinegar through meta-chrome (simultaneous) method of natural dyeing. The K/S values, colour coordinates values and colour differences (ΔE) of the dyed samples were measured. Dyeing fastness properties of the dyed silk fabrics were assessed for washing, rubbing and light. TheP.praesorediosumextracts yielded beige to dull brown shades using BWM and pinkish-purple using AFM, whereas theH.leucomelosextracts produced yellowish-brown shades for both BWM and AFM on the silk substrate. Modanting seemed to be effective in increasing the K/S values of all mordanted fabrics except in the case of silk fabric dyed withP.praesorediosumextracted from AFM. Fastness ratings to washing and rubbing were all very good (5-4) for bothP.praesorediosumandH.leucomelosdyed silk fabrics. The fabrics dyed withP.praesorediosumandH.leucomelosextracts produced strong and deep colours as their ΔE values were higher and increased obviously of all mordanted fabrics. It can be concluded thatP.praesorediosumandH.leucomelosextracted from BWM and AFM methods can be used as an alternative dye source.

Coconut husk is considered waste and its fibers can be used as a source of natural dyes for textiles. The objective of this research is to obtain natural dyes from old coconut (Cocos nucifera) husk waste fibers through the extraction process. Brown color was produced in the liquid-liquid extraction method. The brown color natural dyes were then used to dye cotton cloth. Three different binding agents were used during the fixation process, i.e. tunjung, naphtol salt, and alum. The coloring results of the natural dye on the cotton cloth were as follow: with alum binding agent the resulting color was light brown (cream), whereas tunjung binding agent produced a greenish brown color, and using napthol salt binding agent produced yellow color. The colored cotton cloths were tested for their color fastness properties against rubbing, soap washing, and sunlight exposure. The measurement scale used was grey scales, which was used to evaluate the color change (color fading) and color staining (color transfer) during color fastness testing. In general, based on the results, the colored cotton cloth using alum as binding agent showed better color fastness properties against rubbing, soap washing, and sunlight exposure compared to the ones using tunjung and naphtol salt binding agents.
