Q:Cotton and polyester fiber with the advantages and disadvantages of Aaron

Cotton fiber is a natural plant cellulose fiber, moisture absorption, breathable and comfortable, but the appearance of flat, stiff, easy to wrinkle.

Q:What is the density of polyester?

Poly (ethylene terephthalate) is prepared by esterification of terephthalic acid two methyl ester with ethylene glycol ester or esterification of terephthalic acid with ethylene glycol. The average molecular weight (2-3) x 104 of the crystalline saturated polyester is 1.5-1.8. The average molecular weight is equal to the molecular weight. The relative density is 1.368., the melting point is 225 DEG C, the flow temperature is 243 DEG C: the glass transition temperature is 80 DEG C, Martin is heat-resistant 80 DEG C, the thermal deformation temperature is 98 DEG C (1. 82MPa), and the decomposition temperature is 353 DEG C. With good mechanical properties, high rigidity, high hardness, low water absorption and good dimensional stability. Good toughness, impact resistance, friction resistance and creep resistance. Good chemical resistance, soluble in cresol, concentrated sulfuric acid, nitrobenzene, three chloroacetic acid, chlorophenol, insoluble in methanol, ethanol, acetone, alkane. Use temperature -100 ~ 120 degrees centigrade.

Q:What is a new type of recycled fiber?

Modal fiber is a new kind of cellulose fiber. The raw material of Modal fiber comes from the wood of nature. It can be degraded naturally after use. Because of this kind of fiber is made of natural cellulose as raw material is biodegradable, serious environmental pollution problems and produce similar viscose fiber in fiber production process, is a new environmental protection fiber, twenty-first Century. Modal fiber is half the price of Tencel fiber and is the second generation of regenerated cellulose fiber. Modal fiber can be blended and interwoven with a variety of fibers, to play their respective characteristics of fiber, to achieve better effect. Modal fabric has better moisture absorption and breathability than pure cotton fabric. It has a soft feel, good drape, comfortable wearing and bright color. It is a kind of natural mercerized fabric.

Q:Polyester fiber shoes how to maintain, a little pilling, and a bit dirty?

So, polyester fiber shoes as much as possible with other shoes change, wear clean, wipe with wet cloth can wash, then easy to yellow, and it is difficult to remove stains, don't use brush and other friction cleaning

Q:What are the clothes made of chemical fiber?

Acrylic fiber: commonly known as "artificial wool", with soft, warm and strong good features, surface smooth, compact structure, not easy to deformation, washed after shrinking extremely small.Viscose: material chemical material processing in wood, cotton linter, reed containing natural cellulose into, is also often called artificial cotton, with basic properties of natural fibers, dyeing properties, good fastness, soft fabric, more than major, good hygroscopicity, good drape, wearing cool, not easy to produce static electricity, pilling and the ball.Acetate fiber: made from cellulose containing natural material. It has silk style. It is light and comfortable to wear. It has good elasticity and resilience. It is not suitable for washing and has poor color fastness.

Q:What's the acid and alkaline difference between wool and cellulose fiber?

The acid and alkali properties of the two are just the oppositeYou also want how many original, ask questions, one hundred times will not copy, copy others, don't believe, then ask!

Q:What fabric is polyester fiber?

Has the advantages of strong wear resistance, a crisp sense, easy washing, easy to dry, color fastness is good, do not fade not shrink. 80s is the popular Dacron blended polyester fabric. Not afraid of disadvantage, Mars, air permeability, water will become transparent, fabric friction parts will be the light, poor thermal performance etc..

Q:Can polyester fabric come into direct contact with the skin?

Secondly, it is best not to say, polyester is polyester, is a completely without any hygroscopic synthetic fiber, long-term contact with the skin will be itching, pricking flu. Cotton, hemp and silk are no match for natural fibers.

Q:Which is good, MDF or particleboard? Why?

[] compared with particleboard surface density of large, intermediate small strength mainly in the surface, can not destroy the surface, so basically no plasticity, but particleboard bonding force between layers or better, nail holding ability! Suitable for making plane right angle plate, which is commonly known as panel furniture. Such as office furniture, kitchen cabinets, wardrobes and so on.

Q:Nitrocellulose (collodium) toxic?

Cotton, viscose, cotton, fire fire Collodion nitrocellulose solution, for trauma, injury, because of the dry shrink film, hemostasis, promote wound healing and protection.
