Problems solved by technology

At present, the common production methods of aromatic textiles include spraying, padding and dipping, etc. Attaching fragrances to polyester fibers or fabrics has the advantages of simple process and easy operation, but the fragrance release is not long-lasting and cannot be washed.
Due to the low boiling point and volatile characteristics of flavoring agents, it is difficult to meet the requirements of adding modification in the high-temperature synthetic polyester process; using aromatic masterbatch compounding or composite spinning, only aromatic type with low melt spinning temperature can be seen. polypropylene report
[0004] There are many reports on hydrophilic and antistatic modified polyester fibers, but there are no reports on polyester fibers with long-lasting aromatic odor, hydrophilic and antistatic functions, and easy coloring.

[0030] A preparation method of aromatic, hydrophilic and antistatic composite functional polyester fiber includes the following steps:

[0031] Step 1. Preparation of aromatic polyester masterbatch: Put 80-93Wt% low-melting polyester chips into a drum dryer, dry for 6-10 hours under the conditions of vacuum ≤200Pa and 70-120℃, then crush Fine powder with a particle size of 100-500 mesh, add 2-8wt% flavor, 2-5wt% antistatic agent, 1-4wt% dispersant, 1-3wt% coupling agent and 0.1-0.5wt% antioxidant, and stir Mix thoroughly; then granulate by a screw extruder to obtain aromatic polyester masterbatch. The particle size of the aromatic polyester masterbatch is equivalent to that of low-melting polyester chips; wherein the melting point of the low-melting polyester chips is 150 ~170℃, the intrinsic viscosity is 0.62~0.68dl / g; the fragrance is a powder fragrance for plastics that can withstand high temperatures above 250℃; the antistatic agent is one or one of metal powders or metal com...

Abstract

The invention discloses a preparation method of aromatic, hydrophilic and antistatic composite functional polyester fibers. High-temperature-resisting powdery essence is selected and uniformly mixed with low-smelting-point polyester powder, an antistatic agent, a dispersant, a coupling agent and an anti-oxidant, and then the mixture is extruded and granulated to prepare aromatic polyester master batches. Double-screw-rod composite spinning equipment is adopted, a mixture of the aromatic polyester master batches and low-smelting-point polyester slices is used as a core and a constant-pressure cation dyeable polyester chip is used as a skin to prepare the aromatic, hydrophilic and antistatic composite functional polyester fibers. The composite functional polyester fibers prepared by the invention can release aromatic flavor for a long period and have washing endurance; the hydrophilic property is strong and the moisture regain reaches more than 0.8 percent; the aromatic, hydrophilic and antistatic composite functional polyester fibers have an antistatic function and the specific resistance is M*10<7>omega.CM (M is more than or equal to 1.0 and less than 10); the aromatic, hydrophilic and antistatic composite functional polyester fibers are easily colored and strong in color fastness.

Description

Technical field [0001] The invention relates to the technical field of differentiated polyester fibers, in particular to an aromatic, hydrophilic and antistatic composite functional polyester fiber, and a preparation method and application. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for the comfort of clothing and home textile fabrics that are closely related to life. Therefore, in order to meet the needs of the market, a lot of work has been done on differentiated polyester fibers and fabrics at home and abroad, and good results have been achieved. [0003] The aromatic scent released by aromatic textiles has the advantages of making people happy, resisting fatigue, and improving immunity. Since its inception, it has been favored by the market. At present, the common production methods of aromatic textiles include spraying, padding and dipping. The fragrance is attached to polyester fibers or fabri...
