What is Jute Grading? | Grading System of Jute

Jute Grading:

Jute is a natural vegetable fiber under the category of bast fibers like flax, hemp, kenaf and ramie. Since ancient times, it has been traditionally grown in the eastern part of the Indian subcontinent, which make up of the present day West Bengal of India and plains of Bangladesh. Grading is done after the barky ends are cut off. There are six grades both for White and Tossa jute. The characteristics specified for various grades are given below.

Jute Yarn Manufacturing Process | Production Process of Jute Yarn

Manufacturing Process of Jute Yarn:

Raw Jute:

Raw jute in the form of bales are processed in jute mills to produce hessian, sacking, jute yarn, bags, and other useful products. Raw jute bales from jute fields or suppliers, carried by trucks are unloaded are stacked in the jute mills gowdown. 

Selection of Raw Jute:

In the selection process, raw jute bales are opened to find out any defect and to remove the defective portion from the mora by experienced workers. Raw jute bales are of two types i.e. 150 kg weight and 180 kg weight with or without top portion cutting. The bales are assorted according to end use like Hessiean weft, Sacking wrap, Sacking weft etc. After selection, jute bales are carried to softning section by workers called Gariwala and Bajawala.

Classification of Jute Fiber

Classification of Jute:
Classification of jute according to the quality (Geographical distribution according to Bangladesh):

1. Jat
2. District
3. Northern

Jat:

• Jat is the finest quality jute with firm
• It has good color and length
• It has good luster

Jute Products | Some Important Products of Jute

Jute Products:
Jute has versatile use in our day to day life. Some products of jutes are highlighted in below:

Jute Bags : Jute Hand Bags , Jute Beach Bags, Jute Shopping Bags, Jute Sling Bags, Jute Christmas Bags, Jute Sacking Bag, Jute Promotional Bags, Jute Bottle Bags, Jute Hessian Cloth Bags, Jute Hydro-Carbon Free Bags, Jute Food Grade Bags 

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.
