Problems solved by technology

The disadvantage of this type of elastic fiber application is: it cannot be used as bare silk, and it must be covered with other fibers as a core yarn to have practical value; it needs special core yarn equipment to process, and the processing process is long and the elasticity is difficult to control Uniform; at the same time, this type of elastic fabric has the disadvantages of easy relaxation and poor chemical stability when used repeatedly
The functions obtained after finishing, on the one hand, are difficult to last, on the other hand, they will affect other performances

Embodiment 1

[0024] The invention provides a technical solution: a method for preparing an elastic wool fabric of functional polyester composite filaments, the steps are as follows:

[0025] (1) Preparation of composite polyester filament: Polyethylene terephthalate (PET) and polytrimethylene terephthalate (PTT) are used in a composite ratio of 60 / 40 to obtain a fineness of 65D composite white silk; or add PET-based masterbatch and PTT-based masterbatch respectively in the spinning process to obtain composite yarn with the same fineness range and dope coloring;

[0026] (2) Yarn forming method of weft yarn: Doubling the composite white silk or dope-dyed composite yarn in step (1) and 80Nm / 2 wool / polyester 50 / 50 blended spun yarn with 790Z twist / m on the doubling machine, and Twisting obtains the doubling yarn of twist 980S twist / m; Control wool yarn doubling tension to be 5.96g, filament doubling tension to be 2.32g, make composite white silk or composite silk be in the state of straighten...

Embodiment 2

[0031] The invention provides a technical solution: a method for preparing an elastic wool fabric of functional polyester composite filaments, the steps are as follows:

[0032] Select PET and PBT polyester composite filaments: slice PET, the viscosity is 0.8dl / g, the fineness of PET and PBT polyester composite filaments is in the range of 330dtex, and the strength is 2.2cN / dtex. Slice PBT with a viscosity of 1.4dl / g, put them into different corresponding melting tanks, and mix functional masterbatches in the corresponding melting tanks. The functional masterbatches include antibacterial masterbatches, antistatic masterbatches Granules, anti-permeable masterbatches and quick-drying masterbatches. Through the respective spinning channels to the spinneret, extruded side by side to obtain composite white silk and wool or wool blended spun yarn, the composite ratio is 70 / 30;

[0033] Select functional masterbatch or functional PET filament with special-shaped cross-section in the...

Abstract

The invention discloses a functional polyester composite filament elastic wool fabric and a preparation method thereof. PET / PBT elastic polyester filaments compounded by PET polyester and PBT polyester, or filaments compounded by functional PET filaments and elastic PBT filaments on a composite elasticizing machine through elasticizing, and composite yarns formed by wool or wool blended spun yarns through doubling, Sirofil, core-spun yarns and the like are used as weft yarns, and the PET / PBT composite filament is a stock solution colored or white self-crimping filament; and the woolen fabric has 5%-40% tensile elasticity in the weft direction. According to the functional polyester composite filament elastic wool fabric, the wool fabric having the advantages of lasting elasticity, controllable elasticity, antibacterial property, anti-permeation property, antistatic property, quick-drying property and the like can be provided, the problem that an existing wool fabric is difficult to achieve the functions and the elasticity can be solved, and the functional wool elastic fabric having the advantages of excellent composite performance and high cost performance can be achieved.

Description

technical field [0001] The invention relates to the technical field of new textile materials, in particular to an elastic wool fabric of functional polyester composite filaments and a preparation method thereof. Background technique [0002] The elasticity of wool fabrics is usually achieved by covering core-spun yarns formed with wool (or wool blended) yarns covered with elastic fibers such as spandex (such as Lycra) and polyolefins (such as XLA fibers of DOW Company). The disadvantage of this type of elastic fiber application is: it cannot be used as bare silk, and it must be covered with other fibers as a core yarn to have practical value; it needs special core yarn equipment to process, and the processing process is long and the elasticity is difficult to control Uniform; at the same time, this type of elastic fabric has the disadvantages of easy relaxation and poor chemical stability when it is used repeatedly. Ordinary polyester composite elastic filaments that need t...
