Optimum Drafting Conditions of Polyester and Viscose Blend Yarns

In this study, we used an experimental design to investigate the influence of the total draft, break draft, the distance between the aprons (Clips) and production roller pressure on yarn quality in order to obtain optimum drafting conditions for polyester and viscose (PES/CV) blend yarns in ring spinning frame. We used PES fibres (1.4 dtex × 38 mm long) and CV fibres (1.6 dtex × 38 mm long) to spin a 20 Tex blend yarn of PES (70%)/CV (30%) blend ratio.

When the break draft, adjustment of distance between of aprons and roller pressure is not reasonable, controlling and leading of the fibres is not sufficient for proper orientation of the fibres in the yarn structure to produce a high-quality yarn. Experimental results and statistical analysis show that the best yarn quality will be obtained under drafting conditions total draft of 38, 1.2 break draft, 2.8 mm distance between of aprons and maximum pressure of the production top roller (18daN).

Types of textile fibers – list of textile fibers by its sources

Fiber is a fine hair-like structure and is considered the raw materials of textiles. The fiber is extracted from various sources for commercial use. In addition to obtaining from animals, plants, and minerals, many of the fibers are artificially generated as well. Here is a list of most commonly used textile fibers.

Natural silk – sourcing, usage, and application

Silk is a natural protein fiber. It is similar to wool in that it is composed of amino acids arranged in a polypeptide chain. Silk is produced by the larvae of a moth, while wool is produced by animals. All protein fibres have some general characteristics in common.

Eco-Friendly Fibers and Organic Fibers

Textiles Industry has many working procedures which form flow processes. Each process makes various influences on the environment and human health.Therefore, many eco-friendly fibers have been invented which do not require the use of any pesticides or chemicals eg. bamboo, hemp, Ramie, mud silk etc.

Microscopic appearance of Fibers

The microscopic test is a technical test that involves identifying the fabric with the help of a microscope with a magnification of minimum 100 power. The test can easily distinguish between fibres.

Characteristics of Rayon Fiber

Rayon is moisture absorbent (more so than cotton), breathable, comfortable to wear, and easily dyed in vivid colors. It does not build up static electricity, nor will it pill unless the fabric is made from short, low-twist yarns.

Rayon—The Multi-Faceted Fiber

Of all the fibers, rayon is probably the most perplexing to consumers. It can be found in cotton-like end uses, as well as sumptuous velvets and taffetas. It may function successfully in absorbent hygiene and incontinence pads and equally well-providing strength in tire cords.
