What is Flax Fiber | Properties of Flax Fiber | Uses of Flax Fiber : Flax is that the strongest among the natural cellulosic fibers. It’s a bast. Flax fiber is taken out from the skin of the stem of the flax plant. Flax is manufactured into linen yarn for thread or woven fabrics. So it’s also name as linen. It’s also one in every of the oldest fibers. which was used over 30,000 years before. Linen cloth made of flax was wont to wrap the mummies within the early Egyptian tombs.
Properties of Flax Fiber:
Flax fiber is lustrous, flexible and soft; bundles of fiber have the looks of pale hair. It’s wont to make most of the luxurious cloth which is most comfort to dress. Flax fiber absorbs humidity well and could be a very breathable fiber.
Physical Properties of Flax Fiber:
- Length: The typical length of fiber differs from 18-30 inch.
- Effect of Heat: Linen has a superb resistance to degradation by heat. It’s good conductor of warmth. So linen sheet are so cold in summer season.
- Color: Brownish, light, ivory, grey.
- Elongation at break: The elongation at break is approximately 1.8% (dry) & 2.2% (Wet).
- Good Abrasion Resistant: Because the linen fiber is sweet in strength, it also has good abrasion resistance.
- Tenacity: Flax may be a very strong fiber because it’s very crystalline polymer system permits its extremely long polymers to make more hydrogen bonds than cotton polymers. Tenacity varies from 6.5 to eight gm/denier.
- Hygroscopic nature: Flax fiber is extremely
- Specific Gravity: Relative density is 1.54.
- Absorbency: Absorbency is sweet. It absorbs moisture and dries more quickly. It’s excellent for manufacturing towels and handkerchiefs.
- Resiliency: Very poor.
- Effect of moisture: Standard moisture regain is 10 to 12%.
- Dimensional stability: Good but easily tend to crease.
- Comfortable: Linen may be a comfortable fabric.
- Lusture: it’s brighter than cotton fiber and it’s slightly silky.
Thermal Properties of Flax Fiber:
- Excessive application of warmth energy causes the flax fiber to scouch, char and burn. This can be a sign that flax isn’t thermoplastic. Which can be attributed to the extremely long fiber polymers and therefore the countless hydrogen bonds they form.
- Flax has the most effective heat resistance and conductivity of all the commonly used textile fibers.
Chemical Properties of Flax Fiber:
- Effect of organic solvents: Resistant of common solvents (Acetone, ether, methyl, alcohol, Chloroform Etc.)
- Bleaching Actions: Cool chlorine and hypo-chlorine whitener doesn’t affect the linen fiber properties.
- Acids Effect : Flax will survive in weak acids but is attacked by hot dilute acids or cold concentrated acids.
- Effect of Micro Organism: Linen fiber is attacked by fungi and bacteria.
- Effect of insects: Moth, grubs or other insects do not attack flex fibers.
- Dye ability: It’s no good attraction to dyes. Direct and vat dyes are appropriate for flax fiber.
- Effects of Alkali: Linen has a wonderful resistance to alkali. It doesn’t stricken by the strong alkali.
Uses of Flax Fiber:
Flax is two to a few times stronger than cotton fiber, but less elastic.The simplest grades are accustomed make linen fabrics like damasks, sheeting and lace. Coarser grades are used for the manufacturing of rope and cord, and historically for canvas and webbing equipment. Flax fiber is additionally used as a material within the high-quality paper industry for the utilization of printed banknotes and cigarette paper for tea bags and tissue manufacture.It’s also hypo-allergenic then a wonderful choice of fiber for those with allergies.
Flax fiber has a crucial application as material. It’s a cellulosic fibers, like wood and plant fibers; it’s the potential to be used as load-bearing constituents in composite materials thanks to their attractive properties like high stiffness-to-weight ratio that produces cellulosic fiber composites ideal for several structural applications.
Common uses of flax fiber:
- Sewing thread
- Bed linen
- Decorative fabrics
- Clothing apparel
- Wall coverings
- Luggage fabrics
- Handkerchief linen
- Kitchen towels
- Surgical thread
- Dish towels
- Fabrics for light aviation use
- Table wear
- Used in automotive industry
- Artist’s canvases
- In geotextiles (ground-cover materials).
- Insulation purposes
- Flax could conceivably be mixed with excess grass seed straw or softwood fiber in composite boards
- Reinforce plastics and composite materials.
