Description
Technical Field
The invention belongs to the technical field of fiber manufacturing, and particularly relates to olive-containing polyester fiber and a preparation method thereof.
Background
The polyester fiber is an ideal textile material, can develop various high-grade fabrics, and has good market prospect. However, as the living standard of people is continuously improved, the requirements of consumers are also continuously improved, and some defects of the terylene are more and more obviously exposed, such as: poor moisture absorption and air permeability, soft hand feeling which is not as soft as cotton, poor functionality, difficult modification and the like.
The polyester fiber is characterized in that the basic component of the polyester fiber is polyethylene terephthalate, the molecular formula is HO-H2C-H2C-O [ -OC-Ph-COOCH2CH2O- ] n, polyester fiber (PET) is obtained due to the fact that a large number of ester groups exist on a molecular chain, the chemical structural formula of a long chain molecule of the polyester fiber is H (OCH2CCOCO) NOCH2CH2OH, the relative molecular weight of polyester used for the fiber is generally about 18000-25000, the molecular weight of the wool-like polyester is low, and the molecular weight of the industrial polyester is high. In practice, small amounts of monomers and oligomers are also present. These oligomers have a relatively low degree of polymerization and are present in cyclic form. The polyethylene terephthalate can be prepared by polycondensation after preparing 9BHET (ethylene terephthalate) from terephthalic acid (PTA) and Ethylene Glycol (EG) by a direct esterification method.
From the view of the composition of terylene molecules, the terylene is composed of short aliphatic hydrocarbon chains, ester groups, benzene rings and terminal alcoholic hydroxyl groups. Except two terminal alcoholic hydroxyl groups, the terylene fibers have no other polar groups, so the hydrophilicity of the terylene fibers is very poor. The terylene molecule contains 46% of ester group, which can be hydrolyzed and thermally cracked at the temperature of over 200 ℃ and hydrolyzed by soap when meeting strong alkali, so that the polymerization degree is reduced, the common detergent powder used at the temperature of below 100 ℃ has no influence on terylene, and the terylene molecule also contains aliphatic hydrocarbon chain, which can make the terylene molecule have certain flexibility, but because the terylene molecule contains benzene ring which can not rotate, the terylene macromolecule is basically rigid molecule, and the molecular chain is easy to keep linear. Therefore, the polyester macromolecules are easy to form crystals under the condition, so that the crystallinity and the orientation of the polyester are high.
Olive, a plant of the genus Olea of the family Burseraceae. The height can reach 35 m, and the diameter at breast height can reach 150 cm. 3-6 pairs of small leaves, paper to leather, 12-16 pairs of lateral veins and developed middle veins. The inflorescence is axillary. The length of the infructescence is 1.5-15 cm, and 1-6 fruits are contained. Oval to spindle-shaped, yellow-green at maturity, thick outer peel, hard core, pointed ends at both ends, and coarsened core surface. The flowering period is 4-5 months, and the fruit is mature in 10-12 months. The olive is a good windproof tree species and a street tree. The wood can be used for shipbuilding and used as a sleeper. For manufacturing furniture, agricultural implements, building materials, and the like. The fruits can be eaten raw or pickled; it can be used for treating laryngitis, hemoptysis, polydipsia, enteritis, and diarrhea. The core is used for carving and is also used as medicine for fishbone sticking in throat. The kernel is edible, and can be used for extracting oil, and the oil can be used for preparing soap or lubricating oil.
Olive extracts have been used as one of the important raw materials for medical and health care.
