Apparel Testing

Testing is a valuable aid for textile production, distribution, and consumption. During textiles testing the variation of a fibre or fabric i.e. length, colour, fineness, threads per inch, cover factor, is detected properly. Continuous test of the textiles results a enhanced and efficient output of the production. By Apparel Testing we can evaluate and ensure the quality of the garments to be used by the end users.

Zipper – fasteners on garments

The zipper is a popular device which acts as a fastener for temporarily joining two edges of the fabric. The zipper is a part of the everyday costume. Also called slide fastener. a device used for fastening clothing, valises, etc., consisting of two toothed tracks or spiral metal or plastic coils, each bordering one of two edges to be joined, and a piece that either interlocks or separates them when pulled.

Labels used on Textile Articles

Symbols are written on labels, attached to textiles to indicate how a particular item should best be cleaned. Textile and apparel labels can help you consider alternative choices and make better buying decisions if you take time to read them. Permanent Care Labels (PCL) use symbols to explain how to care for wearing apparel and home sewing fabrics, so consumers need to learn the basic symbols.

Plain Weaves – weaving pattern

Plain weave is the most common and tightest of basic weave structures in which the filling threads pass over and under successive warp threads and repeat the same pattern with alternate threads in the following row, producing a chequered surface. They do not ravel easily but tend to wrinkle and have less absorbency than other weaves. The plain weave is variously known as Calico or Tabby weave. It is the simplest of all weaves having a repeat size of 2.

Drafting Plans in weaving

A draft indicates the number of heald shafts used to produce a given design and the order is which warp ends are threaded through the heald eyes of the heald shaft. The principle of drafting (i.e. putting of ends on different healed shafts) is that ends which work in different order require separate heald shafts. To keep matters simple, we can also say that the ends that work alike are put on the same heald shaft.

Fabric Weaving Basics

The process of producing a fabric by interlacing warp and weft threads is known as weaving. The machine used for weaving is known as weaving machine or loom. Weaving is an art that has been practiced for thousands of years. The earliest application of weaving dates back to the Egyptian civilization. In order to interlace wrap and weft threads to produce a fabric, the basic mechanisms necessary for any type of looms are Primary, Secondary and Auxiliary mechanisms.

Types of Fabric Weaving Looms

Weaving is the process of making fabrics by interlacing the threads lengthwise and widthwise commonly known as warp and weft in a regular order. The operation is performed in a machine called a loom. Two sets of yarns are interlaced, almost always at right angles to each other. One, called the warp, runs lengthwise in the loom; the other, called the filling, weft or woof, runs crosswise. The raising and lowering sequence of warp threads in various sequences give many possible weave structures.

Substrate Formation

Textile substrates are formed from yarns or fiber webs by several techniques including weaving, knitting, tufting, and nonwoven formation. Composites of textile substrates are formed by bonding two fabrics together by use of an adhesive to form a bonded substrate or backed substrate or by application of cut fibers to an adhesive-coated substrate to form a flocked substrate.

Draw frame Functions

Carded Slivers are fed into the Draw-Frame and are stretched/Straightened and made into a single sliver. Also, fibre blending can be done at this stage. The cans that contain the sliver are placed along the draw-frame feeder rack, usually including eight pairs of cylinders (each pair is above the space occupied by a can),the lower cylinder is commanded positively, while the upper one rests on the lower one in order to ensure movement of the relative sliver that runs between the two.
