1. Flax Knowledge
(1) Fiber introduction:
The bast fiber, the process length of flax is generally 55cm, the pectin content is large, and the spinnability is poor. The official moisture regain is 12%, which is the same as cotton in natural fibers, and its wet strength is stronger than its dry strength.
(2) Characteristics of linen textiles:
Flax fiber is the oldest textile fiber in the world, and the fabrics made from flax fiber are very versatile, and can be used as industrial products such as clothing fabrics, decorative fabrics, tablecloths, bedding and automotive supplies. With the emergence of new varieties, new technologies, new spinning methods, new weaving methods and new finishing processes, the development momentum of the linen products industry is getting better and better.
2. What is Flax Wet Spinning Machine?
Flax wet spinning frame is a type of linen ring spinning frame.
It consists of a feeding mechanism, a drafting mechanism, and a twisting and winding mechanism. The roving is drawn from the roving tube on the roving frame, enters the water tank through the guide rod and the porcelain tube, and enters the drafting mechanism through the traverse guide rod after soaking.
The drafting mechanism is a three-roller double-zone large drafting device composed of a feeding roller, a middle roller and a drafting roller (there are also three-roller double-apron drafting and single-apron plus light roller drafting device). The gauge in the drafting zone is smaller than the average length of the process fibers. The feeding roller jaw is composed of the lower feeding roller and the metal groove pressing roller, which is pressurized by spring. The middle and top rollers and the front top rollers are light rollers with semi-hard rubber rings on the surface, both of which are pneumatically pressurized. The feed roller, middle roller and draft roller have grooves on the surface of the lower roller to better hold the fibers.
The roving is drawn and attenuated in the drafting zone, and the process fibers are split. The drafted whiskers are twisted into spun yarns through the yarn guide hook and wound on the bobbin. The water tank contains various penetrants, softeners and other warm water solutions. When the roving passes through the water tank, the colloid between the fibers expands and softens due to the action of the solution, and the contact force between the fibers is weakened, so the process fibers can be split during drafting, and a finer spun yarn can be spun. Uniform dryness, high strength and good color. The spindle speed is about 6500r/min.
In recent years, the spindle speed of new linen wet spinning frame can reach 8000r/min.

3. The Technological Process Of Wet Spinning:
Equipment situation:
combing process (chopping frame), drawing frame, roving frame, scouring pot, spinning frame, winding machine.

Long hemp spinning:
combing into long hemp → combing into hemp for moisturizing and health preservation → blending hemp → hand forming into slivers → grouping → long hemp merging → 1~4 drawing frames → long hemp roving → roving bleaching and refining (sodium chlorite, Hydrogen peroxide) → wet spinning spun yarn → drying → spun yarn color separation → winding → storage
Short hemp spinning:
combing into short hemp → blending with hemp → mixed hemp humidification → combing → needle combing (3~4 lanes) → combing → needle combing → short hemp roving → roving bleaching → wet spinning → drying → spun yarn Color separation→winding→warehousing
