A small sample, usually taken from existing fabric, is called a swatch, whilst a larger sample, made as a trial to test print production methods, is called a strike off. For plain-dyed fabrics it is called a lab-dip , and for yarn-dyed fabrics (like stripes and checks), it is called a handloom .
Other than fiber structure, it is chemical orientation and different finishing methods such as singeing, heat-setting, calendering, silk surfacing, mercerizing, and bio polishing, etc. [1] [7] Cotton when mercerized has a round cross-section that appears brighter than untreated cotton (with a bean cut view.)

In biology, determination is the process of matching a specimen or sample of an organism to a known taxon, for example identifying a plant as belonging to a particular species. Expert taxonomists may perform this task, but structures created by taxonomists are sometimes used by non-specialists.
Other terms including plangi and tritik are Indonesian terms derived from Javanese words for methods related to tie-dye. In Indonesia, tie-dye might be combined with other dyeing technique, such as batik jumputan, which combine tie-dye with batik wax-resist dyeing. [9] Ikat is a method of tie-dyeing the warp or weft before the cloth is woven.
Identifying moths. Identification in biology is the process of assigning a pre-existing taxon name to an individual organism.Identification of organisms to individual scientific names (or codes) may be based on individualistic natural body features, [1] experimentally created individual markers (e.g., color dot patterns), or natural individualistic molecular markers (similar to those used in ...
A simple staining method for bacteria that is usually successful, even when the positive staining methods fail, is to use a negative stain. This can be achieved by smearing the sample onto the slide and then applying nigrosin (a black synthetic dye) or India ink (an aqueous suspension of carbon particles).
Cloth is finished by what are described as wet process to become fabric. The fabric may be dyed, printed or decorated by embroidering with coloured yarns. The three main types of fibres are natural vegetable fibres, animal protein fibres and artificial fibres. Natural vegetable fibres include cotton, linen, jute and hemp.
Fabric quality addresses fabric-related issues. Fabric inspection is a step of visual examination apart from the performance criteria; It finds various flaws and irregularities. Accordingly, it grades the fabrics as per quality level, fabric weight, shading color, number, and size of the defects.
