As the production line of the regenerated celulose fibre at the upper reaches, its production line is high surpasses 100,000 tons/year production capacity, low also all at 50,000 tons/year, can not be connected between the requirement of the large-scale production equipment at the upper reaches and downstream " small lot, many kinds ".Examination is calculated with 50,000 tons/year production capacity, and production line production capacity hourly is 7000 kilograms, and look spins the batch of enterprise cotton dyeing and is merely 100 kilograms.Simultaneously, a kind of colored fibre variety production of color is changed next kind after finishing, because mill base need be known the influence of last consignment of time product attached to producing in the pipeline, need put glue and remove contamination in one hour at least.
This just means that regenerated cellulose enterprise can not connect and is less than 10 tons order, even connect order, its production cost also will be higher than conventional variety far away, and its wastage is very huge.Develop colored fibre though why domestic this also be large-scale cellulose fibre manufacturing enterprise, can't move towards market.
