Q:What are the differences between silk, yarn and fiber three? Where are the differences between decorative fabrics and clothing fabrics?

Depending on the use of different. Most of them are made of yarn or silk. Most of the lines are used for sewing or other industrial / agricultural / military purposes.There are exceptions to all fiber: non-woven fabrics made from fibers are similar to paper making techniques.

Q:What are the advantages and disadvantages of MDF?

Major shortcomingsThe biggest drawback of 1, density board is not moisture, see water swell. Use density board to do the skirting board, door board, should pay attention to six sides painted window board, so as not to deformation.2, the density board meets the water, the expansion rate is big, the deformation is big, the long time load bearing deformation is bigger than the homogeneous solid wood granule board.Although the density board has poor moisture resistance, but the density board surface smooth, smooth, fine material, stable performance, strong edge, easy to shape, avoid the rot, moth eaten and other issues. Are superior in anti bending strength and impact strength of hand and particleboard, excellent decorative plate surface, than solid wood furniture appearance dominates.

Q:Polyester fabric for UV protection?

Polyester fabric does not protect against ultraviolet light.

Q:Nylon and fabric made of clothes which is good, anti UV effect which good?

Polyester fiber, commonly referred to as polyester. Polyester fabric is a kind of chemical fiber clothing material used in daily life. It is suitable for clothing. The bright and shiny, but not soft, with a shiny, smooth, flat, very good elasticity. Squeeze the silk loose and no obvious creases. In addition, the fabric has high strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, acid resistance, alkali resistance, good light resistance, but poor moisture absorption, dyeing difficulties, fabrics easy to wash, quick drying, good shape.

Q:What's the difference between a silver fiber radiation suit and a metal fiber radiation suit?

In the end, anti radiation clothing which kind of material is good, we look at the current market anti radiation clothing mainstream fabric:1: metal fiber blended fabric. Generally use a diameter of about 0.008 millimeters of stainless steel, metal fiber and cotton and polyester fiber blended into fabrics, good fabric shielding value of more than 30DB. It has better flexibility because of the addition of other fabrics. Parameters: breathable, washable, shielding, stable performance;2: all silver fiber knitted fabric. The silver fiber here is not pure silver, but a new composite fiber made of silver ions and ordinary fabric. In addition to having good breathability, it also has the function of bacteriostasis and maintenance to human body. The shielding value of all knitted fabric with silver fiber is above 70DB. This fabric is easy to oxidize, but oxidation does not affect the effect of radiation protection and the use of clothing. Parameters: breathable, washable, antibacterial, maintenance, elimination of static electricity, shielding performance is stable;3: semi silver fiber blend fabric. Silver fiber fabric refers to made of silver fiber and polyester fiber blended fabric, the fabric shielding value between metal fiber and the silver fiber fabric, usually around 50-60DB, antioxidant capacity than the silver fiber fabric, but also has a role in the maintenance of antibacterial. Parameters: breathable, washable, antibacterial, maintenance, elimination of static electricity, shielding performance is stable;

Q:Compared with the traditional reinforcement technology, the reinforcement effect of CFRP sheets is different from the traditional reinforcement technology What's the price of carbon fiber reinforcement?

The carbon fiber reinforcement strength mainly depends on carbon fiber reinforcement drawings, drawings of carbon fiber reinforced high strength, the carbon fiber reinforced the price of intangible higher, the price will be appropriate to lower prices is carbon fiber reinforcement and a factor of carbon fiber reinforcement area and reinforcement strength is not how much high carbon fiber, carbon fiber reinforced carbon fiber reinforced area so the price will be cheaper, the price will be high price and amount of reinforcement of carbon fiber reinforced carbon fiber is not great

Q:What are the basic features of polyester fiber?

Heat resistant polyester is made by melt spinning, and the formed fiber can be melted and heated again. It belongs to thermoplastic fiber. The melting point of polyester fiber is relatively high, but its specific heat, air and thermal conductivity are smaller. Therefore, the heat resistance and heat insulation of polyester fiber are higher. It's the best synthetic fiber. 4. polyester surface smooth, internal molecules arranged closely. Polyester fabric. The heat resistance of synthetic fabric is best, with thermoplastic, making pleated skirt, pleated long. At the same time, the polyester fabric melt resistance is poor, in ash, Mars is easy to form holes. Therefore, when you wear, you should try to avoid cigarette butts, sparks and other contacts.

Q:The difference between polyester and hollow fiber

Is not the same concept, is a kind of fibre, such as polyester, polyamide, polysulfone fiber; one is the fiber cross-section shape: such as tubular (hollow) and circular (solid), cross.

Q:Can the mask made of high electrostatic fiber be washable?

Some enterprises in order to save costs, require employees to use masks after a period of cleaning two times, there are some mask manufacturers also developed in the middle of the traditional gauze masks sandwiching a layer of meltblown non-woven fabric of the so-called "clean," anti-dust masks are wrong, and dangerous behavior.

Q:What are the elastic fibers and collagen fibers?

Elastic fibers (elastic fiber) elastic fiber yellow in loose connective tissue slightly, strong refraction, elastic. Generally more delicate than collagen fibers, fibers have branches, arranged scattered. Its chemical composition is mainly elastin (elastin), which has greater tolerance to traction. Elastic fibers of the skin and tendons are produced by fibroblasts, which are produced by smooth muscle cells in large vessels. Elastic fiber Description: dyed blue, purple, a single distribution, has branches, and woven into a net. SEM observation showed that elastic fiber contained two components: Micro fibril and homogeneous substance. Fibrils are arranged in the form of structural glycoproteins that surround the homogeneous substance, elastin.
