Problems solved by technology

[0003] However, due to the small cohesion force between polyester fibers, polyester fibers have high strength and high elongation ability, especially resistance to bending fatigue, torsional fatigue and abrasion resistance, so polyester fibers are easy to slip out of the surface of the fabric. After forming small balls on the surface, they will not fall off quickly. The small balls will be entangled with each other and kneaded into many small spherical particles.

preparation example 1

[0042] The preparation method of apple fiber is as follows:

[0043] T1. Squeeze the apples to obtain apple pomace and apple juice, the apple juice is reserved;

[0044] T2. Soak the apple pomace in 0.1% sodium chloride solution for 2 hours, then soak in water for 2 hours, squeeze out the water and dry at 65°C, then grind the dried apple pomace, pass through 70 mesh, Apple powder is obtained after 50-mesh and 30-mesh sieves;

[0045]T3. Weigh 10kg of apple powder, add 10kg of water and 0.4kg of cellulase, stir at room temperature for 2 hours, then place in microwave for 20s, and set the microwave power to 700W; then heat to 35°C, stir for 0.5h under microwave Place for 15s; reheat to 45°C, stir for 0.2h, place under microwave for 10s, and place at room temperature;

[0046] T4. Centrifuge the mixture obtained in step T3 and take the supernatant, then soak the supernatant with 3 times the mass of ethanol for 8 hours, then centrifuge again, collect the precipitate and dry to o...

preparation example 2

[0048] The difference between Preparation Example 2 and Preparation Example 1 is that in step T2, the apple pomace is soaked in 0.1% sodium chloride solution for 3 hours, then soaked in water for 1 hour, and dried at 55° C. after being squeezed out of water. In step T3, 0.2 kg of cellulase was added, stirred at room temperature for 1 hour, and then placed in the microwave for 30 s; then heated to 30 °C, stirred for 1 h, and placed in the microwave for 25 s; then heated to 40 °C, stirred for 0.5 h, and then placed in the microwave for 25 seconds. After being placed under the microwave for 20 s, it was placed at room temperature; in step T4, the supernatant was soaked with 3 times the mass of ethanol for 6 h.

preparation example 3

[0050] The difference between Preparation Example 3 and Preparation Example 1 is that in step T3, after adding cellulase to the apple powder, it is stirred and heated at 45° C. for 2 hours and then placed at room temperature without microwave treatment.

Abstract

The invention relates to the field of polyester yarns, and discloses a full-dull polyester filament yarn and a processing technology thereof. The raw materials comprise, by mass, 120-130 parts of polyethylene glycol terephthalate (PET), 10-20 parts of an anti-pilling composition, 2.5-4 parts of matting powder, 4-8 parts of an antioxidant, 3.5-5 parts of a softening agent and 6-10 parts of a dispersant. The anti-pilling composition is a mixture of apple fibers, propolis and high-hydrogen-content silicone oil, and the mass ratio of the apple fibers to the propolis to the high-hydrogen-content silicone oil is (3-5): (0.8-1.5): 1. The full-dull polyester filament yarn is obtained by mixing, melting and extruding an anti-pilling composition, polyethylene glycol terephthalate, matting powder, an antioxidant, a softening agent and a dispersing agent to obtain master batches, melting and spinning the master batches, finally cooling and forming, and finishing the cooled polyester filament yarn with malic acid. According to the full-dull polyester filament yarn, the defect that the full-dull polyester filament yarn is prone to pilling is overcome.

Description

technical field [0001] The present application relates to the field of polyester filaments, in particular to a fully matte polyester filament and a processing technology thereof. Background technique [0002] Polyester is an important variety of synthetic fibers. It is produced by esterification or transesterification and polycondensation with polyethylene terephthalate (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) as raw materials. The obtained fiber-forming high polymer - polyethylene terephthalate (PET). Fabrics made of polyester have the advantages of strong elasticity, wrinkle resistance, not easy to deform, and good heat resistance. Therefore, polyester fabrics are a kind of chemical fiber clothing fabrics that are used more in daily life. [0003] However, due to the small cohesion between polyester fibers, high strength and high elongation ability of polyester fibers, especially good bending fatigue resistance, torsional fatigue resistance and wear...
