Field trials observing the use of woven ropes show encouraging performance, say Pradeep Kulshrestha, Dharmendra Goswami, Chandrakant Nakum, Jagdish Patel


Woven ropes are stronger compared to braided, conventional ropes. The Ahmedabad Textile Industry's Research Association (ATIRA) developed woven ropes with core and sheath arrangements. Comparison was carried out with the same type of braided ropes in terms of material and diameter. In this way we can get the strength of the core yarn. For example, aramid fibres can be covered with polyester to use in the marine industry. Glass fibre can be covered with cotton for aesthetic properties during handling.


The developmental activities carried out in the area of high strength ropes using varieties of high tenacity yarns were carried out to:


1.       To ascertain requirements of different specified industries using ropes. For instance, in the fields of transport, marine, fire fighting, rescue and sports

2.      Testing conventional ropes to analyse raw material used

3.      To evolve cost-effective construction and design of woven ropes with judicious combinations of specific high strength yarn to meet requirements

4.      Developing ropes with equal/higher strengths with the substitute and/or cost-effective raw materials using weaving techniques


Manufacturing woven ropes at ATIRA Incubation Centre

Weaving rope with core-sheath structure of pre-decided design using varieties of yarn:

a)     Rewinding yarn from big package to smaller packages on Sahm Winding Machine

b)     To put those spools on creel as per core and sheath plan on Jakob Muller Narrow Rope Weaving Machine

c)      To draw yarn ends in Heald wires and Reed

d)     To take forward all ends and insert them in guide rollers

e)     To apply open type of Drop Pins in warp stop motion or insert each yarn through close drop pin

f)       To draw weft in needle

g)     To start weaving rope with process monitoring and controls
