Chemical Modification of Jute Fiber

jute fiber

Jute is a natural biodegradable fiber with advantages such as high tensile strength, excellent thermal conductivity, coolness, ventilation function et al.1-2. Recently, due to the improvement of people’s living standards and need for environmental protection, the demand of natural biodegradable and eco-friendly fibers is rising worldwide day by day. Ramie, flax, hemp and some other vegetable fibers have been used as textile materials, but jute fiber is basically used for traditional purposes such as manufacture of sackings, hessian, carpet backing and the like. Taking account of the costliness of ramie and the shortage in sources of flax, and the challenges from the synthetic fibers in the traditional jute products market, if jute could be used to replace ramie and flax partially as textile material, not only the cost could be reduced but also a new market would be provided for jute products.

Physical Properties of Cotton Fiber | End Uses of Cotton Fiber

Cotton Fiber:

Among the seed and fruit fibres, cotton has grown in stature as the most important textile fibre in the world. In fact, cotton is the backbone and basic foundation of the world’s textile trade and industry. Cotton is a natural vegetable fibre produced in the cotton plant in many countries of the world even in Bangladesh also.

Properties of Cotton Fibres:

 
Properties of cotton fiber can be divided into two parts, one is according to physical structure and another is using process.

Chemical Composition of Textile Fiber (Natural) | Chemical Composition of Cotton Fiber/Jute Fiber/Linen/Flax Fiber/Hemp Fiber/Sisal Fiber/Coir Fiber/Wool Fiber/Silk Fiber

Chemical Composition of Natural Fiber:
Every fiber consists of some chemical elements. Such as cotton contains cellulose, protein, pectin etc. Wool contains keratin, dirt, suint etc. Chemical composition of natural fibers are given below:

Chemical Composition of Cotton Fiber:

• Cellulose                                            94%
• Protein                                               1.3%
• Ash                                                    1.2%
• Pectin                                                 1.2%
• Oil, Fat and Wax                                0.6%
• Sugar                                                 0.3%
• Pigment                                              trace
• Others                                                1.4%

Bale Management | Object of Bale Management | Specification of a Cotton Bale

Bale Management:

Testing, sorting and mixing bales according to the properties of fibre for producing specific good quality of yarn at minimum cost is called Bale management.

Object of Bale Management:
1. An evening out of the quality characteristics of a yarn.
2. A means of avoiding quality jumps.
3. A possibility of reducing costs as a result of an improved knowledge of the fibre characteristics.

Production of Cotton Fiber From Field to Mill

Cotton Fiber

Cotton:

Cotton, the purest form of cellulose found in the nature is the seed hair of the plants of the genus Gossypium. It is classified as natural, cellulosic, mono-cellular, staple fiber. Cotton has been cultivated for more than 5000 years. Archeologists found that it was grown and used for textile purposes in the Indus Valley well before 2100 BC, and in Mexico by 3500 BC Cotton has been of service to mankind for so long that its versatility is almost unlimited and new uses are constantly being discovered.
