Bijnor Textile Cluster- Afterthoughts



Visit to Bijnor cluster was enchanting. Situated on the banks of Ganges, I could see the prosperity of powerloom owners in the villages of Sedha, Nahtor and Chandpur. Equally disturbing is the struggle that handloom weavers are facing in Kiwar. A lot needs to be done to improve the condition of that village.



Khadi is made in the village of Peruwala and the looms are pitlooms as compared to Sedha where frame handlooms are used. It was heartening to see a full-fledged reactive dyeing plant in full operation in Nahtore. Could see fabric from Seersucker to lightweight Denim being made on the powerloom.The houses are still of the older generation, having timber roofs with lots of alcoves and thick walls. Out side it was mustard and Sugarcane fields that greeted us everywhere we went. Fresh Gur was being made in the way and its soft aroma was filling our nostrils. Also elections are round the corner, so saw many congregration and announcements. Good to see conditions of roads in general.

Getting Bright Red Color in Vat Dyes



One solution proposed is to mix Brown R and Red 6B.

http://dimachema1.en.made-in-china.com


Brown R chemically has an excellent wash fastness and dry rubbing fastness of 4 and light 6-7. However, its color fastness to rubbing in wet is only 3.  Source

Red 6B chemically also has an excellent wash fastness of 4. However its dry rubbing is only 3-4 and wet rubbing is only 3.  Source

Thus it is difficult to obtain the good rubbing fastness in this combination of dyes.

Twist in Silk



Silk yarn is classified in several ways based on the twist. A some of them are as follows:

Raw Silk
In this the silk is produced by reeling together baves of several cocoons. It has no twist.

Poil Yarn
A silk yarn produced by twisting raw silk. The twist may be slight or exceed 3000 per meter.

Tram Silk
To make a tram yarn, two or more raw silk threads are doubled and twisted slightly. Generally the twist is about 80 to 180 TPM ( Turns per meter)



Crepe
This yarn is made by doubling several raw silk threads and twisting them to very high levels in the range of 2000 to 4000 TPM.

Organzine
This silk yarn is formed by doubling two or more poil yarn and throwing them in a direction opposite to that of the individual yarn. The twist in the poil yarn will be about 700 TPM ‘Z’ and the doubled yarn will have about 950 TPM ‘S’.

Steaming of Twisted Yarn

The twisted yarn has to be subjected to steaming in an autoclave. This process fixes the twist in the thread. Duration of steaming depends upon the depth of layers of threads in the bobbin and twist levels of the thread. Ten minutes is usually sufficient for organza while more highly twisted crepe require considerably more time of about 2 hours.
