Line fabric has the advantages of natural coolness, cleanliness, durability, and crispness that are incomparable to chemical fibers and other natural fibers. Therefore, a great prospect for the sales of linen fabrics is just around the corner. In order to enable everyone to have a deeper understanding of the production of linen fabrics and to quickly and accurately meet customer needs during the sales process, we are now learning flax knowledge with everyone for better communication.
1. Basic knowledge of linen
1. Introduction to fiber:
Bast fiber, the process length of flax is generally 55cm, it has high pectin content and poor spinnability. The official moisture regain is 12%. Among natural fibers, like cotton, the wet strength is greater than the dry strength.
2. Characteristics of linen textiles:
2.1 Coolness: Linen is benign to heat Conductor, wearing linen underwear can reduce the body surface temperature by 4°C; good moisture absorption and release; good breathability; not easy to stick to the skin;
2.2 Cleanliness: The more the gel is washed, the more it falls off. The clothing of waiters in first-class foreign hotels are all linen textiles;
2.3 Strong and durable: 1.6 times stronger than cotton;
2.4 Crisp: Linen clothing has prominent lines and is solemn and elegant.
3. Uses of linen textiles
3.1 Linen clothing cloth 3.2 Linen knitwear 3.3 Handicraft gauze cloth (base fabric for embroidery) 3.4 Linen canvas 3.5 Linen hose 3.6 Linen decorative cloth 3.7 Other products (sanitary cloth, sewing thread, etc.).
2. Linen Spinning equipment and processes
1. Linen spinning classification: pure linen spinning and linen blended yarn
1.1 Linen blended yarn and cotton spinning equipment and The process is the same
Short hemp→Blow cleaning→Card
Draw (3~4)→roving→Spinning yarn→winding→Include
raw cotton→清花→carding
1.2 Pure linen spinning equipment and process
1.2.1成hem→humidification and health→Manual splitting→Bundling→comb comb→Comb into long linen (comb into short linen)
1.2.2 Wet spinning process:
Long linen spinning: combed into long linen→ Comb into hemp and humidify Health→matched linen→Handmade into strips→Group→长马宇合→ 1~4 draw lines→Long linen roving→Roving bleaching (sodium chlorite, hydrogen peroxide) →Wet-spun spun yarn→dry→Spinning yarn color separation→winding→Into the library;
Short linen spinning: combed into short linen → With hemp→Mixed linen humidification→combing hemp→ Needle comb (3~4 lines) →combed→pin comb→Short linen roving→roving bleaching→Wet spun yarn→dry→Spinning yarn color separation→winding→Investment
1.2.3 Equipment status : Combing process (combing machine), draw frame, roving frame, scouring pot, spinning frame, winding machine

3. Linen weaving equipment and process
3.1 Fabric classification: pure linen fabric, interwoven fabric, blended fabric;
3.2 Weaving process: winding-warping-sizing-reeding;
3.3 Equipment used: Pure linen fabric weaving equipment is rapier loom and shuttle loom (yarn count range is 4.5s~21s);
3.4 Interwoven fabric weaving: In most cases, the warp yarn is pure cotton or other yarn, and the weft yarn is linen yarn;
3.5 blended fabric weaving: can be done on a jet machine (the yarn count range is more than 21 and the hemp content is less than 30%);
3.6 Sizing situation of pure linen varieties: Low count and low density varieties do not need sizing.
4. Main fabric defects of linen fabric
Main flaw: rungs , thinning, poor weaving, skipping, holes, broken edges and shrinkage, broken warp, broken weft, thinning, oil stains
5. Other technical indicators of linen
Elongation of dyed cloth
The elongation rate of linen fabric varies greatly depending on the variety and equipment. The elongation rate of large varieties can reach 22~12%, while the elongation rate of small varieties can be 3~5%. Small The elongation of the rapier is about 3 points greater than the elongation of the large rapier.
