Define Blending | Fibre Blends | Advantages of Blending | Methods of Blending

Blending is the combining of different fibres together intimately to achieve a desired product characteristic. Blends can influence colouring, strength, softness, absorbency, ease of washing, resistance to wrinkling, ease of spinning, cost, etc. 

High Speed Spun Yarn Production | Rotor Spinning | Friction Spinning | Self twist Spinning |Twist less Spinning

Much research has been done to develop a spinning system for staple fibres that will shorten the yarn spinning by eliminating some of the steps of the conventional spinning. The research is oriented in simplifying the yarn manufacturing process and to produce yarns more economically. In these recent developments the

Define Silk Yarns | Process Flow Chart of the Production of Silk Fibre | Manufacturing Process for Silk Yarns

Silk is a natural protein fibre which is obtained from the cocoons of the silkworm. It is a natural filament produced by the salivary glands of silkworms, which are a type of moth that feeds on the mulberry bush. They spin their cocoons using a complex set of mechanisms within their bodies

Difference Between Woolens and Worsteds Yarn

The differences between woolen and worsted yarns are as follows:

Woolen fabrics have a soft feel and fuzzy surface, very little shine or sheen, will not hold a crease, and are heavier and bulkier than worsteds. Blankets, scarves, coating, are from woolen yarns. Worsted wool is smoother than woolen, takes shine more easily, does not sag, holds a crease well

Manufacturing Worsted Yarns | Manufacturing Woolen Yarns

Manufacturing Worsted Yarns: Now, we would learn the steps involved in manufacturing worsted yarns. In the manufacturer of worsted yarns, the Different steps involved are:

• Carding
• Gilling and combing
• Drawing
• Roving
• Spinning

Manufacturing Processes for Wool Based Yarns | Production Processes for Wool Yarns

Wool is the fiber derived from the hair of domesticated animals, usually sheep. Wool is classified according to the source from which it is obtained. The fleece or the wool which is collected is kept to the different stages of manufacturing process which starts with the preparation of the fiber. The different stage through which it is taken depends upon whether the fiber

Sewing Thread Winding System | Different Types Winding | Precision winding | Parallel winding

A transformer winding in which all the turns are arranged on a bobbin instead of in the form of a disk. Generally used for the high-voltage windings of small transformers.

Uses of Sewing Threads, Embroidery Thread | Necessities of Sewing Threads

Sewing thread is a flexible, small diameter yarn or strand usually treated with a surface coating, lubricant or both, intended to be used to stitch one or more pieces of material or an object to a material. It may be defined as smooth, evenly spun, hard-twisted ply yarn, treated by a special finishing

Process Flow Fhart of Sewing Thread | Different Types of Packages are Used in Sewing Threads

A thread is a large number of very thin fibers spun together, used in the manufacture of textiles and in sewing. Or In hardware a thread is used to connect two things together, such as a screw to a piece of wood or two segments of a hose.

The process flow chart for the manufacture of sewing threads is shown in the flowchart.

Sewing Threads | Different Types of Sewing Threads

Sewing Threads

Sewing threads can make or mar a garments, and hence a through understanding of their processing and properties is vital for the industry to choose the right type of the threads. According to the definition given by ASTM, sewing thread is a flexible, small diameter yarn or strand usually

Properties of Sewing Threads | Essential Properties Required for Sewing Threads

Essential properties required for sewing threads: Industrial sewing techniques make specific and often very exacting demands on the threads involved in the sewing process. The sewability of sewing threads is of major importance6, having a very profound effect on seam quality and production costs

Feature of Yarn Ring Spinning frame | Drafting Zone | Ring & Traveller | Rubber Cots and Apron | Yarn Twist

Yarn Ring Spinning frame Technology is a simple and old technology, but the production and quality requirements at the present scenario puts in a lot of pressure on the Technologist to select the optimum process parameters and machine parameters, so that a good quality yarn can be produced at a lower manufacturing cost.

Yarn Twist | Twisting Process of Yarn | Mechanism of twist insertion to the strand

Twisting is a very essential process in the production of staple yarn, twine, cord and ropes. Twist is inserted to the staple yarn to hold the constituent fibres together, thus giving enough strength to the yarn, and also producing a continuous length of yarn. The twist in the yarn has a two-fold effect;

Spandex | Physical and Chemical Properties of Spandex

Spandex, Lycra or elastane is a synthetic fibre known for its exceptional elasticity. It is made up of a long chain polymer called polyurethane, which is produced by reacting a polyester with a diisocyanate. Spandex gained interest quickly due to it’s superiority to the strength in durability of rubber. Spandex also has a better resistance to dry heat & oil, in comparison to rubber. The level of comfort and wicking ability found in Spandex are unparalleled, and do not exist in such high amount with any other fabric

Yarn | Classification of Yarns | Yarn Designation

Yarn is a product of substantial length and relatively small cross-section consisting of fibres or filaments with or without twist. It is the long fine structures capable of being assembled or interlaced into such textile products as woven and knitted fabrics, braids, ropes, and cords.

Assumptions of an Ideal Yarn Geometry | Properties of Ideal Yarn

The following yarn properties should have a textile yarn if it is said as a ideal yarn-

1. The yarn in circular in cross-section and is uniform along its length.
2. Yarn is composed of concentric layers of different radial.
3. Each fibre follows a uniform helical path around one of the concentric cylinder so that its distance from yarn axis remains constant.
4. A fibre at the centre will follow a straight line of the axis.
5. The axis of circular cylinders coir sides with yarn axis.
