The heat dissipation performance of flax is five times that of wool and 19 times that of silk. In hot weather, wearing linen clothes can lower the skin surface temperature by 3-4 degrees Celsius than wearing silk and cotton fabrics.
Second, fuck.
Flax can absorb 20% of its own weight of water, at the same time, it can quickly release the absorbed water, and it can keep dry even if it sweats a lot.
Third, reduce perspiration.
Helps maintain the electrolyte balance of the human body. The research shows that linen clothing can reduce human perspiration 1.5 times than cotton clothing.
Fourth, radiation protection.
Wearing a pair of linen trousers can greatly reduce the effects of radiation, such as the decrease in the number of male sperm caused by radiation.
Five, anti-static.
Only 10% flax in the blended fabric is enough to prevent static electricity. It can effectively relieve people's anxiety, headache, chest tightness, dyspnea and other symptoms caused by electrostatic environment.
Sixth, inhibit bacteria.
Flax has a good inhibitory effect on bacteria and fungi, and can effectively prevent some diseases. According to Japanese researchers, linen sheets can prevent bedsores in patients who have been in bed for a long time, and linen clothes can help prevent and treat some skin diseases, such as common rashes and chronic eczema.
Extended data:
Flax, also known as crow hemp and flax, can be divided into three categories: fiber, oil and fiber oil, all of which belong to broomcorn millet. Because of its good hygroscopicity, fast moisture conduction and relatively fine diameter, it is one of the main fiber raw materials for clothing in spring and summer. Usually, the cloth made of flax fiber is called flax fabric.
Flax fiber exists in bast tissue of hemp stem. After retting and degumming, part of the gum is removed, so that the adhered fiber bundles are partially loose, and then pressed and pulped to make "hemp", which is a process fiber composed of 10 ~ 20 single fibers.
After the fiber and flax are harvested together, they are bundled into small bundles for retting and degumming. The warm water temperature of retting should be controlled between 28 ~ 32℃. After about 100 hour, the hemp stalks should be taken out, placed in an umbrella shape and dried in the open air.
Rain and dew retting is to spread the harvested hemp stalks on grass or hemp ground, then soak them in rain and dew and ferment them with mold. After 7 ~ 10 days under suitable humidity conditions, the retted stems are broken, xylem and impurities are removed, fibers are combed, and then sorted. The short hemp knocked out is called the second coarse hemp.
The price of high-quality pure flax sold in the market is higher. The price can also reflect the quality of flax. Cheap flax is mostly made of hemp fiber, and the fiber is short. Individual businesses sell semi-hemp and mixed cotton and hemp. We can distinguish them in the following ways.
(1) Check whether the longitude and latitude lines are even. If the warp and weft are too uniform, it may be cotton fabric.
(2) Tighten the cloth sample and check the knitting density.
(3) High-quality primary color linen is brown, shiny and even in water absorption. Flax with poor hemp quality is treated into soft fiber, which absorbs water unevenly and turns black when wet.
(4) Worsted linen outside, the less plush on the surface, the better.
(5) The vertical and horizontal tightness of semi-hemp is different.
(6) Pull a thread. If both ends are bent and bifurcated, the thread is cotton. The torn flax thread should be smooth at both ends, otherwise it will be impure.
(7) If caustic soda is applied to the canvas, linen will turn brown and cotton will turn pale yellow.
