Bamboo Fiber | Bamboo Fabric | Production Process of Bamboo Fabric | Uses of Bamboo Fabric

Bamboo fibres are cellulosic fibres produced from Bamboo Plants a type of grass. There are two methods of producing bamboo fibres namely Mechanical method & Chemical method. Mechanical methods are similar to Flax production ( retting, enzyme treatment, boiling, scutching, cutting etc.,) and this gives Natural bamboo fibres. There are two types of Chemical methods namely Bamboo

Define Batching | Batching | Factors Considered for Batch Selection

Batch: A blend of different types of jute is made up to suit the particular class of yarns being spun. This blend is known as ‘the batch’.
Batching: All the processes starting from batch selection up to carding of jute is called batching.

A bast fiber used for sacking, burlap, and twine as a backing material for tufted carpets. Jute is one of the most affordable natural fibres and is second only to cotton in amount produced and variety of uses of vegetable fibres. Jute fibres are composed primarily of the plant materials cellulose (major component of plant fibre) and lignin (major components of wood fibre).

Characteristics of Nylon Fabrics | Physical and Chemical Properties Nylon Fabrics

Nylon is very much suitable for hosiery and the knitted fabrics because of its smoothness, light weight and high strength. Nylon is a lustrous fibre. The lustre of the fibre can be modified by adding the delustering agent at the molten stage.

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. 

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

Wool Fiber | Properties of Wool Fiber | Classification of Wool

Wool fiber
Wool fiber is the natural hair grown on sheep and is composed of protein substance called as keratin. Wool is composed of carbon, hydrogen, nitrogen and this is the only animal fiber, which contains sulfur in addition. The wool fibers have crimps or curls, which create pockets and give

Glass Fiber | Types of Glass Fiber | Properties of Glass Fiber | Manufacturing Processes of Glass Fiber | Uses of Glass Fiber or Glass Yarn

Glass fiber
Glass fiber also called fiberglass. It is material made from extremely fine fibers of glass Fiberglass is a lightweight, extremely strong, and robust material. Although strength properties are somewhat lower than carbon fiber and it is less stiff, the material is typically far less brittle

What is Modacrylic fiber | Properties of Modacrylic Fiber | Uses of Modacrylic Fiber | Application of Modacrylic Fiber

Modacrylic fiber
Modacrylic fiber is a manufactured fiber in which the fiberforming substance is any long chain synthetic polymer composed of less than 85% but at least 35% by weight of acrylonitrile units. (-CH2CH[CN]-)x. A modacrylic is a synthetic copolymer. Modacrylic fiber is inherently flame resistant.

What is Elastoester Fiber | Properties of Elastoester Fiber | Uses of Elastoester Fiber


Elastoester is an official FTC generic fiber type defined as: At least 50% by weight aliphatic polyether and at least 35% by weight polyester. Elastoester is similar to polyester, but different enough physically to warrant a new generic name under the FTC’s Textile Labeling Rules

Melamine Fiber | Properties of Melamine Fiber | Manufacturing Process of Melamine Fiber | Applications of Melamine Fiber | Uses of Melamine Fiber

Melamine fiber is a manufactured fiber in which the fiber-forming substance is a synthetic polymer composed of at least 50% by weight of a cross-linked melamine polymer. Melamine fiber is a cost effective heat resistant fiber based on melamine chemistry, with a 400°F (200°C) continuous operating temperature. Melamine fibers are flame resistant, have outstanding heat/dimensional stability, and are self-extinguishing. EFT’s WF series of melamine fibers have a fiber length distribution tailored for use in wet-laid nonwovens. Typical fiber lengths are in the 1-12mm range, and they show excellent dispersion and formation in wet-laid processes.

Production Process of Melamine Fiber

The production process is proprietary. It is based on a unique melamine chemistry that results in a cross-linked, non-thermoplastic polymer of melamine units joined by methylene and dimethylene ether linkages. In the polymerization reaction, methylol derivatives of melamine react with each other to form a three-dimensional structure. This structure is the basis for the fiber's heat stability, solvent resistance, and flame resistance.

Applications of Melamine Fiber
  • Mattresses, Home Furnishings / Nonwovens
  • (Compliant with 16CFR1633)
  • Specialty flame resistant papers
  • Firefighting apparel
  • Electrical papers
  • Transmission / friction papers
  • Filtration media
  • Engineered materials / Short-fiber composites
  • Adhesives / Fillers
  • Tire sealants

Flax is also called Linen. The fibre is obtained from the stalk of a plant (Linum Usitatissimum - A literal translation is “linen most useful.” ) which is from 80 to 120 cm high, with few branches and small flowers, of a colour which varies from white to intense blue, which flowers only for one day. Common flax was one of the first crops domesticated by man.
