Batch Selection technique to produce different types of Jute Yarn




1. Hassian warp: to make this type of yarn clean and defect free jute is required. Hassian warp yarn is good quality, clean and free from speck with high lustre.

            Batch selection:           Hard jute →→→ 70%
                                                Soft jute →→→ 30%

            Example: for 8 lbs/spyndle hassian warp
                                                White C →→→ 40%
                                                White X →→→ 40%
                                                Tossa →→→ 20%

2. Hassian weft: Hassian weft yarn is cleaner and softer than hassian warp yarn. So for hassian weft clean fibre is required, but fibre of strength can be used to hassian weft yarn.

Batch selection:           For heavy yarn
Hard jute →→→ 30%
                                                            Soft jute →→→ 70%

                                                For light yarn
Hard jute →→→ 50%
                                                            Soft jute →→→ 50%

Example: for 8.5 lbs/spyndle hassian weft
                                                White C →→→ 20%
                                                White X →→→ 50%
                                                Tossa →→→ 30%



3. Sacking warp: Sacking warp jute yarn is good and strong. Specks and colour is not important when manufacturing this type of yarn.

Batch selection:           Hard jute →→→ 60%
                                                Soft jute →→→ 40%

            Example: for 8 lbs/spyndle sacking warp
                                                X bottom →→→ 67%
                                                S M R →→→ 33%
                                               






4. Sacking weft: Sacking weft yarns are low quality yarn. It is coarse and is made from low grade jute fibre. It may contain line cuttings, bale cuttings, soft and hard waste, rope waste, jute dust, habijabi and entangled jute.

Example: for sacking weft
                                                NC →→→ 70%
                                                S M R →→→ 15%
                                                Caddis →→→ 5%
                                                Thread waste and gunny cuttings → 10%

5. C.B.C (carpet breaking cloth):
Batch selection:           Hard jute →→→ 100%
                                               
            Example: for 8 lbs/spyndle C.B.C warp
                                                B.W.B →→→ 40%
                                                B.W.C →→→ 60%

Example: for 8 lbs/spyndle C.B.C weft
                                                B.W.B →→→ 30%
                                                B.W.C →→→ 70%
