Description
Technical Field
The invention relates to the technical field of novel textile materials, in particular to an elastic wool fabric of functional polyester composite filaments and a preparation method thereof.
Background
The elasticity achieved by wool fabrics is usually achieved by covering the elastic fibers with wool (or wool blend) yarns, such as spandex (e.g., Lycra), polyolefins (e.g., XLA fibers from DOW corporation), to form core yarns. The disadvantages of this type of elastic fiber application are: the bare yarn can not be applied, and the bare yarn is required to be coated by other fibers as a core yarn, so that the utility value is realized; the processing can be carried out only by special core-spun yarn equipment, the processing flow is long, and the elasticity is difficult to control uniformly; meanwhile, the elastic fabric has the defects of easy relaxation and poor chemical stability when repeatedly used for many times. After being colored by stock solution, the common polyester composite elastic filaments needing high-temperature and high-pressure dyeing can realize relatively lasting elasticity by means of ingenious organizational structure design, for example, patent ZL2007 patent polyester composite filament parallel linear latitudinal elastic wool fabric and preparation method thereof, patent ZL2007 patent polyester composite filament inter-latitudinal elastic wool fabric and preparation method thereof, and a method for realizing wool fabric elasticity by adopting PET/PTT polyester composite filaments is provided. However, it is clear that because PET/PTT requires high temperature and high pressure dyeing, and cannot piece-dye wool fibers, dope dyed filaments are required to achieve the elasticity of wool fabrics. The problems that the color light of wool fibers is difficult to coordinate, the fabric is easy to have flash and different colors, and the like exist.
Various excellent properties are the trend of future development of wool fabrics. On the basis of meeting the requirement of rich colors, the fabric has comfortable elasticity and also has functionality such as antibiosis, antistatic or anti-penetration. On the basis of elastic realization, certain functions such as antibiosis, penetration prevention, static resistance, moisture absorption and quick drying are added to the wool fabric through after-finishing. The function obtained by the afterfinish is difficult to persist on the one hand and can have an effect on other properties on the other hand.
Therefore, we propose an elastic wool fabric of functional polyester composite filaments and a method for preparing the same to solve the above problems.
