Example Embodiment

[0019] Example 1

[0020] A modified polyester fiber prepared from the following raw materials by weight:

[0021] 90 parts of PET slices, 3 parts of glyceryl monostearate, 3 parts of hydroxyethyl cellulose, 2 parts of Chinese medicinal extract, 1 part of chitosan, 1 part of titanium carbide powder.

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

[0023] The preparation method of the above modified polyester fiber includes:

[0024] Preparation of Chinese medicinal extract: weigh 20 parts of Maqianzi, 17 parts of Cassia seeds, 16 parts of Pinellia ternata, 15 parts of Puhuang, 12 parts of Epimedium, 10 parts of Ligustrum lucidum, 8 parts of Polygala, 6 parts of Dandelion and Paijiangcao Mix 4 parts, add 10 times the weight of water and decoct twice, the first time is 2 hours, the second time is 1 hour, the two decoctions are combined, and then vacuum dried to obtain an extract with a density of 1.2g / ml;

[0025] Preparation of modifier: take glyceryl mon...

[0030] 1. Clinical data

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

[0032] Diagnostic criteria: Developed according to the diagnostic criteria of neurasthenia in "Neurology". (1) Debilitating symptoms: such as mental fatigue, mental retardation, difficulty concentrating, memory difficulty, work or study can not last, and efficiency is reduced. (2) Excitement symptoms: brain use for work or study can cause mental excitement; memories and associations increase, uncontrollable; may be sensitive to sound and light; but it does not manifest as an increase in speech movement. (3) Emotional symptom...

[0042] Typical embodiment

[0043] Song Moumou, male, 26 years old, a college student in a senior high school. Due to the pressure of finding a job after graduation, he often suffers from headaches, insomnia, memory loss and other symptoms. He often quarrels with his roommates due to trivial matters and is impatient; the diagnosis is For "neurasthenia", conventional treatment + auxiliary treatment of the present invention was adopted. After one course of treatment, the mood was obviously calm and relaxed, the sleep treatment improved, and memory was significantly improved, and there was no recurrence in the follow-up for half a year.

[0044] Gong Mou, female, 47 years old, caused depression and anxiety due to family affairs, 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 can be controlled to a certain extent, but t...

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 ...
