Problems solved by technology

[0005] In recent years, fiber materials improved by traditional Chinese medicine have been released. The improved fiber of traditional Chinese medicine can have certain therapeutic or auxiliary therapeutic effects and is favored by people. However, it is difficult to find long-lasting best-selling products on the market. The main reasons are that the preparation method is simple, The drug adhesion is poor, the treatment effect is not obvious, and the color of the fabric is yellow, the hand feels hard, and the washing resistance is poor, which is not acceptable by people.

Embodiment 1

[0020] A modified polyester fiber, which is prepared from the following raw materials in parts by weight:

[0021] 90 parts of PET slices, 3 parts of glycerol monostearate, 3 parts of hydroxyethyl cellulose, 2 parts of traditional Chinese medicine extract, 1 part of chitosan, and 1 part of titanium carbide powder.

[0022] The particle size of the titanium carbide powder is above 1000 mesh.

[0023] The preparation method of above-mentioned modified polyester fiber comprises:

[0024] Preparation of traditional Chinese medicine extract: weigh 20 parts of Nuxychia, 17 parts of Cassia, 16 parts of Pinellia, 15 parts of Puhuang, 12 parts of Epimedium, 10 parts of Ligustrum lucidum, 8 parts of Polygala, 6 parts of Dandelion and Patrinia 4 parts were mixed, decocted twice with 10 times the weight of water, the first time was 2 hours, the second time was 1 hour, the two decoctions were combined, and then vacuum-dried to obtain an extract with a density of 1.2g / ml;

Embodiment 2

[0030] 1. Clinical data

[0031] Case selection: All 120 cases were outpatients or inpatients. They were randomly divided into a treatment group and a control group, of which 60 people were in the treatment group, including 35 males and 25 females, aged 26-59 years; and 60 people in the control group, 32 males and 28 females, aged 23-61 years. There was no significant difference between the two groups in terms of age, gender, and clinical manifestations after statistical analysis.

[0032] Diagnostic criteria: formulated according to the diagnostic criteria for neurasthenia in "Neurology". (1) Debilitating symptoms: such as mental fatigue, mental retardation, difficulty in concentrating, difficulty in memory, unsustainable work or study, and reduced efficiency. (2) Symptoms of excitement: working or studying with the brain can cause mental excitement; memory and associations increase, which cannot be controlled; sensitivity to sound and light; but does not manifest as increa...

[0042] typical embodiment

[0043] Song Moumou, male, 26 years old, a college student in a fourth-year university. Due to the pressure of finding a job after graduation, he often suffers from headaches, insomnia, memory loss and other symptoms, and often quarrels with his roommates because of trivial matters, and is irritable. "Neurasthenia", using conventional treatment + the adjuvant treatment of the present invention, after a course of treatment, the mood was obviously calmed down, the sleep therapy improved, and the memory was significantly improved, and there was no recurrence in the follow-up for half a year.

[0044] Gong, female, 47 years old, due to family affairs, caused mental depression and anxiety, often felt dizzy, dizzy, unresponsive, prone to insomnia, dreaminess, poor memory, and was diagnosed as neurasthenia by the hospital. After taking a lot of western medicine Treatment, the condition is controlled to a certain extent, but once the drug is stopped, the con...

Abstract

The invention belongs to the technical field of chemical fiber products, and discloses a modified polyester fiber which is prepared by PET slices, glyceryl monostearate, hydroxyethyl cellulose, Chinese medical extract, chitosan and titanium dioxide powder. The invention also provides a preparation process of the modified polyester fiber. The preparation process mainly comprises the following steps of 1) preparing the Chinese medical extract, 2) preparing a modifier and 3) preparing the modified polyester fiber. The modified polyester fiber is unique in preparation process and reasonable in compatibility of materials; at the same time, the physicochemical properties of the materials do not change, so that the market requirements can be satisfied.

Description

technical field [0001] The invention relates to the technical field of chemical fiber products, in particular to a modified polyester fiber and a preparation process thereof. Background technique [0002] Polyester fiber is an important variety of synthetic fibers, and it is the trade name of polyester fiber in my country. It is a fiber-forming high polymer prepared from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation reactions - polyethylene terephthalate Esters, fibers made by spinning and post-processing. Polyester fiber is the simplest one among the three major synthetic fibers, and the price is relatively cheap. In addition, it has the characteristics of strong and durable, good elasticity, not easy to deform, corrosion resistance, insulation, crispness, easy washing and quick drying, etc., so it is loved by people. There are many types of polyester fiber fabrics. In addition ...
