Q:What is a review of fiber anti cracking agent?

1, double protection, double effect. It contains two kinds of anti swelling components, such as micro expansion agent and synthetic fiber, which can improve the anti cracking ability of concrete from two aspects of physics and chemistry, and provide double protection for concrete.2, special water retention components, improve maintenance efficiency. The unique water retention component can prevent evaporation of water at the early stage of hydration. As the hydration proceeds, the water is released, thereby improving the maintenance efficiency.

Q:How are fibers classified?

Common fibers: recycled and synthetic fibres.Special fiber: high temperature resistant fiber, high strength fiber, high modulus fiber, radiation resistant fiber.

Q:Are bamboo fibers counted as artificial cotton?

No, because artificial cotton is dissolved in the solvent in the fiber, and then from the very fine nozzle to form filaments, similar to spider drawing. Bamboo fiber is a kind of cellulose fiber extracted from natural bamboo. It is the fifth natural fiber after cotton, flax, wool and silk. Bamboo fiber has good air permeability, instant water absorption, strong abrasion resistance and good dyeing properties, and has the functions of natural antibacterial, bacteriostasis, mite removal, deodorization and anti ultraviolet.

Q:Is 100% polyester fiber good?

Polyester fiber generally refers to polyester fiberAdvantages: fabric crisp, smooth, bright color. Pregnant bone elastic, moisture absorption, good ventilation, smooth surface, there is a certain waterproof function.Disadvantages: from static electricity, feel bad.

Q:What's the difference between chemical fiber goods and pure cotton?

Cotton is a generic term for various types of cotton textiles. It is used to make fashionable clothes, casual clothes, underwear and shirts. The utility model has the advantages of easy warm, soft close, hygroscopicity, permeability is very good. It is easily the shortcomings shrinkage, easy to wrinkle, the appearance is neat and elegant, dress must constantly pressing.

Q:What are the advantages of polyester fabric?

Polyester fabric resistant to all kinds of chemicals, good performance. Acid and alkali have little damage to them, and they are not afraid of mildew or insect eaten. Polyester fabric is a kind of chemical fiber clothing fabric used in daily life. What is the fabric of polyester fiber polyester fiber is fifty-six to tell you what fabric knowledge fabric polyester fabric several polyester fiber fabric cotton dress cotton fabric must master Q polyester Sourcebook

Q:Which is good, hemp or bamboo fiber?

This depends on your requirements which the hemp more durable, other than bamboo, hemp now are used to make the car seat! It's no use making bamboo fibres for socks and towels! The use value is very high

Q:How do you distinguish cotton from polyester fiber in appearance?

Burning method, cotton burning quickly, polyester fiber burning black smoke, and burning, burning coke.

Q:Polyester fiber, polyester, acrylic, spandex have any harm to the body?

The main manifestations of skin itching, especially at night.In addition, acrylic fibers are used as underwear materials, and tiny fibers clog up the milk ducts, which are harmful to lactating females.

Q:What about polyester fabric? How about air permeability?

Polyester fiber generally refers to polyester fiber, fabric quality is the result of comprehensive performance, as outlined below, your question is only the last line to answer, but I think you need to know something:The main physical and chemical properties of polyester fiber1. form: Polyester vertical surface straight, smooth, cross section is round (can be changed to special-shaped, such as triangle, hexagon, etc.). Polyester acid and not alkali, because polyester macromolecules in the ester base in the hydrolysis, but also can use appropriate alkali for polyester silk imitation treatment. (alkali reduction treatment)2., stretch and flexibility: polyester high strength, stretch growth, resilience, good, ordinary polyester strength of 35.2 ~ 52.8cN/tex, breaking elongation rate of 30% to 40%. According to the different processing, polyester has high strength, low extension, low strength, high extension and so on. Because of its high strength, great elasticity and good elasticity, polyester fiber has good wear resistance, which is second only to nylon. In addition, the high modulus polyester fabric, so crisp, good dimensional stability.3. moisture absorption and dyeing: Polyester structure close, high crystallinity, internal macromolecules without hydrophilic gene, so low moisture absorption, dyeing difficult. Polyester in general atmospheric conditions, moisture regain is only 0.4%. Therefore, the fabric has the advantages of easy washing and quick drying, and also reflects the defects of poor sweat absorption and poor ventilation.
