The ramie stripes produced of Domestic Combined eckling machine, through pre-gill box 1,2 two procedures, enter combing machine again, and then through

gill box

1,2,3,4 four procedures.In this four procedure visual coarse-fibred quality, can determine to carry out three roads or four procedures, but crucial is last procedure, type selecting one is decided to be the B442 type, the shaping bucket is one barrel of two ramie stripes, and ramie stripes directly feeds fine spining machine then, otherwise easily causes the misdraft of ramie stripes, influence quality, reduce floor space simultaneously.Be packaged into product behind the last directly feeding dry-spinning fine spining machine spinning channels and collaterals tube.The type that this technology is selected for use all is that employing is homemade.The raw material of this process using can be 100% second hards, is the main body composition with the second hards perhaps, adds machine cast tow, the flax two thick and low number flax scutched lines of an amount of ratio.

The invention has the advantages that: can be source material with rudimentary second hards, the production yarn be weaved out final products as flax Tarpauling, bunting, mount cloth, in, products such as thick garment material and senior rope yarn.All adopt home-made model, can eat up the breakings material under long-term the overstocking.Its technological process is short, small investment, high efficiency.

Description of drawings:

Fig. 1 is that dry spinning technique for flax coarse fiber is a FB(flow block);

1 second hards raw material, 2 humidification healths, 3 carding machines, 4 combined cards, 5 pre-gill box 1,6 pre-gill box 2,7 combing machines, 8 gill boxes, 1,9 gill box, 2,10 gill boxes, 3,11 gill boxes, 4,12 dry-spinning fine spining machines, 13 winders, the packing of 14 finished products.

Embodiments of the invention:

Dry spinning technique for flax coarse fiber is to be raw material with rudimentary second hards, produces final products, has increased value-added content of product.Bast fibre spinning that equipment choosing is homemade and wool spinning equipment, equipment performance reliably can satisfy the spinning process requirement, and the second hards fiber is through shredding, removal of impurities, combing slivering, and then by ramie stripes feeding dry-spinning fine spining machine, spinning count is public of 3-10.Its technological process is:

Second hards is a raw material, humidification health, carding machine C111B, combined card FY201 type, pre-gill box 1B302 type, pre-gill box 2B304 type, combing machine B311D type, gill box 1B304 type, gill box 2B423 type, gill box 3B432 type, gill box 4B442 type, dry-spinning fine spining machine FY561 type, groove drum winder 1332MD type, finished product packing.Its detailed process:

Humidification health: buy from raw material plant and to contain raw material assorted 38 ± 3%, that thick and stiff mixed and disorderly fiber is twisted together into piece mutually, is difficult for loosening, must alleviate each road feeding load as much as possible, with the damage of minimizing to fiber and equipment, humidification health 24 hours, regain is controlled at 11-14% and promptly is available on the machine.

Carding machine and combined card are removal of impurities and the key equipment of getting rid of short flannel, are the further shredding of second hards, removal of impurities and combing.Carding machine: key technology is that feeding must be fed even few feeding, and makes the fiber crops volume evenly.The main technologic parameters of carded and connection comb: space between working as cylinder and the speed of feeding numb roller, worker rollers, stripper roller, speed ratio and each and all look two crude fibres and order.Reach the second hards fiber at last and be not subjected to tear strongly the requirement of breaking and remove impurity.

Pre-grilling: be that division of the fiber in the ramie stripes and reason is straight, make it to be arranged in parallel, improve the ramie stripes uniformity.

Combing: the ramie stripes of pre-pin 2 is still contained assorted 7-8% and removes short flannel, make it to have good spinning performance, key parameter is the length of choosing: general two crude fibres are the 35-42 millimeter, are the 65-80 millimeter through the average fiber length of combing, percentage of impurity 0.9-1%.

Grilling: look two crude fibre quality and be defined as three roads or four roads.But last crucial procedure must be arranged, and type selecting one is decided to be the B442 type, and one barrel of two ramie stripes of shaping bucket are convenient to ramie stripes and are directly fed the single face fine spining machine, reduces misdraft, is beneficial to and improves the quality of products.
