Ramie strikes the fine washing process of fiber crops point
Technical field
The invention belongs to ramee post processing manufacture field, is related to a kind of ramie processing technology, particularly ramie strikes fiber crops
Divide fine washing process.
Background technology
It is well known that ramee belongs to natural fiber, ramee is obtained by ramie.Ramie is that one kind can fill
The Nature Fibre Textile resource for utilizing, China is divided to have using the advantage of this Nature Fibre Textile resource of ramie, because Chinese
Ramie yield account for global more than 90%.
Ramie is Urticaceae Section of Genus Boehmeria, is perennial root herbaceous plant.The structure in the cross section of Ramie Stalk is by outer
Inwardly it is followed successively by epidermis, bast fiber layer, xylem and marrow.The main purpose of people plantation ramie is to obtain bast fiber layer
Fiber.People obtain ramee bar by operations such as stripping fiber crops, drawing-offs first, then keen-witted and capable to obtain to the fine washing of ramie point
Fiber crops.
As far as the applicant is aware, current ramie industry is typically with disk flax stamping device to the mode of the fine washing of ramie point striking
Fiber crops, are followed by the ramie after being tapped by artificial transfer and are manually rinsed to rinse bath, followed by by artificial transfer rinsing
Ramie afterwards is manually bleached to bleaching cistern.It has been found that every procedure of the fine water-washing method of this ramie point and often
Artificial participation is required between procedure, its automaticity is low, because automaticity is low, causes production efficiency low, point
Fine water washing effect is poor, water resource and various industrial chemicals(Such as NaOH, hydrogen peroxide)Waste serious, the fine washing of this ramie point
The gel content of the degummed ramie that mode is obtained is 10% or so.Therefore, for this present situation, it is a kind of that applicant feels the need to research
Brand-new ramie strikes the fine washing process of fiber crops point, to meet actually used needs.
Disclosed in Chinese patent literature CN105421024A《A kind of ramee method of modifying》(Application number:
201510912550.5), its step is:The alkali neutralization one of one dealkalize of degumming one caustic dip of fiber crops one is washed, and the caustic dip is NaOH
Solution, it is 125-135g/L to do fiber crops concentration, and wet numb concentration is 190-210g/L, and bath raio is 1:10-1:12, temperature is 30-60 DEG C,
