Embodiment 1
[0023] A polyester filament super-spun cotton fabric, which is made of warp and weft yarns through traditional techniques. First, the warp and weft yarns are made of super-spun cotton made of polyester filaments; in particular, the polyester filaments are made of The polyester resin weight is based on 2.5% filaments mixed with elongation enhancer and melt-spun.
[0024] Among them, the addition ratio of the elongation enhancer is such that the particle density on the surface of the filament reaches 15 / 100μm 2 Among them, the glass transition temperature of the elongation enhancer is selected to be 100°C.
[0025] The preparation method of the polyester filament in the above polyester filament super-spun cotton fabric, concrete spinning steps are as follows:
[0026] (1) First add polyester filaments to 2.5% filaments based on the weight of polyester resin, then add elongation enhancer mixture, and perform melt spinning at a spinning speed of 2500-5000m / min;
[0027] (2) natu...
Embodiment 2
[0030] On the basis of Example 1, the polyester filament of this embodiment is formed by blending and spinning 3.5% of the filament based on the weight of the polyester resin and an elongation enhancer, specifically, the elongation enhancer The addition ratio is such that the particle density on the surface of the filament reaches 20 / 100μm 2 Among them, the glass transition temperature of the selected elongation enhancer is 110 °C. Utilize the production method of embodiment 1 to produce, obtain the polyester filament super-spun cotton fabric of the present embodiment.
Embodiment 3
[0032] On the basis of Example 1 or 2, the polyester filament of this embodiment is formed by mixing and spinning 3.0% of the filament based on the weight of the polyester resin and an elongation enhancer, specifically, the elongation The addition ratio of the reinforcing agent is such that the particle density on the surface of the filament reaches 18 / 100μm 2 Among them, the glass transition temperature of the selected elongation enhancer is 104 °C. Utilize the production method of embodiment 1 to produce, obtain the polyester filament super-spun cotton fabric of the present embodiment.
