Description
Technical field
The present invention relates to fiber product technical field, specifically, relate to a kind of modified polyester fibre and preparation technology thereof.
Background technology
Polyster fibre is an important kind in synthetic fiber, is the trade name of China's polyester fiber.It is with p-phthalic acid or dimethyl terephthalate (DMT) and ethylene glycol for raw material is through esterification or ester exchange and polycondensation reaction and obtained fiber-forming polymer---polyethylene terephthalate, through the fiber that spinning and post processing are made.Polyster fibre is that in three large synthetic fiber, technique is the simplest a kind of, and price is also more cheap.Add it and have durable, good springiness, not yielding, corrosion-resistant, insulation, the feature such as well-pressed and quick-drying washable, by people are liked.The kind of polyster fibre fabric is more, except knitting the pure terylene fabric of system, also has many and various textile fabric blend polyester or intertexture product, compensate for the deficiency of pure dacron, given play to and better played performance.
The present age, people rhythm of life was accelerated, the general high-pressure of spirit, and it is increasing to suffer from neurasthenic patient.Neurasthenia refers to that brain is due to long-term nervous and stress, thus produce weakening of cerebration ability, its principal character is spirit easily excitement and mental fatiguability, sleep-disorder, failure of memory, headache etc., with symptoms such as various Somatic discomfort, the course of disease is delayed, heavy time light during symptom, and state of an illness fluctuation is normal relevant with socio-psychological factor.Most of case person of being engaged in mental work occupies the majority.Even this disease reaches several years many decades as dealt with improperly to delay.As new mental element or deficiency of having a rest, symptom can be reappeared or aggravate.Neurastheniac often feels mental and is short of physical strength, and easily tired, operating efficiency is low, often has Somatic discomfort sense and the sleep-disorder such as headache, exists without organic disease.Main manifestations is that especially easily excitement is especially easily tired again for spirit: excitation time patient often loses control of and recalls and association, and a point stimulation is all difficult to stand; Time tired, most patient can feel mental not enough very soon, feels dizzy, can not beat spirit, absent minded or can not concentrate lastingly, decrease of memory, is tiredly even from head to foot short of physical strength.Secondly, patient always feels to be nervous, and especially easily worried, exciting or fly into a rage, and the depressed or hypochondriacal idea of LA even appears in somebody.
In prior art, treating neurasthenic mode has a lot.Doctor trained in Western medicine, in treatment neurasthenia, mainly comprises the following aspects: 1. Cure for insomnia.Only be used for the treatment of the medicine of insomnia at present clinically.Though barbiturates such as secobarbital sodium etc. are also in application, due to easy habituation, now few use.2. antianxiety tranquilizing soporific.Conventional various anxiolytic drugs is stable, the high logical sequence of surazepam, intrazepam, oxazepan, A Pu, roller, Flurazepam such as.Lip river, sea god etc.3. some are used to regulate the medicine of nervous function, as brain tonic mixture, ingredients that many hospitals prepare.The traditional Chinese medical science thinks inernal injuries caused by seven emotions, internal organs imbalance of yin and yang, and the deficient or double phlegm of qi and blood is held concurrently in fire, wet, the stasis of blood etc. and disturbed the main pathogenesis that gods are these diseases.Neurasthenia belongs to the category such as " strongly fragrant disease ", " insomnia ", " consumptive disease ", " palpitaition ", and Chinese medical discrimination is divided into: syndrome of stagnation of liver qi, syndrome of disharmony between heart and kidney, syndrome of deficiency of both heart and spleen.Its pathogenesis, many genus qi and bloods and visceral dysfunction, deficiency of vital energy blood fortune is smooth, and channels and collaterals running is obstructed.Treat then unobstructed for principle with QI-blood circulation.Traditional Chinese Medicine experts is pointed out, although all neurastheniacs are because caused by cerebration overstretched, brain excitement inhibit feature disorder for a long time, it is different for bringing out the root that these situations occur.As fire excess from yin deficiency, the deficiency of liver-yin and kidney-yin, stagnation of liver qi, heart spleen virtual loss, the insufficiency of the kidney yang, hyperactivity of yang due to yin deficiency, the insufficiency of heart and spleen etc. reason all can cause neurasthenia.
In recent years, the fibrous material having had Chinese medicine to improve emerges, and Chinese medicine improvement fiber can possess certain treatment or auxiliary therapeutic action, is subject to the favor of people; But difficulty has lasting best-selling product to occur on the market, traces it to its cause and mainly contains, preparation method is simple, and drug attachment is poor, and result for the treatment of is not obvious, and cause fabric color jaundice, feel hardens, washing durability is poor, can not accept by people.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of modified polyester fibre, the preparation technology of this modified polyester fibre is unique, selection drug matching is reasonable, can auxiliary curing neurasthenia effectively, simultaneously, the physicochemical property of material own does not change, and can be applicable to the market demand.
Technical scheme of the present invention realizes in the following way:
A kind of modified polyester fibre, it is prepared from by the raw material of following weight portion:
PET cuts into slices (polyester slice) 90 parts, glycerin monostearate 3 parts, hydroxyethylcellulose 3 parts, Chinese medical concrete 2 parts, shitosan 1 part, carbonized titanium powder 1 part.
Present invention also offers the preparation technology of above-mentioned modified polyester fibre, mainly comprise the steps: 1) prepare Chinese medical concrete; 2) modifier and 3 is prepared) prepare modified polyester fibre.
Preferably, specifically comprise the steps:
1) Chinese medical concrete is prepared: take vomiting nut 20 parts, cassia seed 17 parts, the tuber of pinellia 16 parts, cattail pollen 15 parts, barrenwort 12 parts, the fruit of glossy privet 10 parts, polygala root 8 parts, dandelion 6 parts and field pennycress 4 parts mixing, add the soak by water twice of 10 times of weight, 2 hours first times, second time 1 hour, merge twice decoction liquor, then vacuumize obtains density is the medicinal extract of 1.2g/ml;
2) prepare modifier: get glycerin monostearate 3 parts according to weight portion, hydroxyethylcellulose 3 parts, Chinese medical concrete 2 parts, shitosan 1 part and carbonized titanium powder 1 part, centrifugal mixer 3 minutes, mixing speed is 1000 revs/min, obtains modifier;
3) modified polyester fibre is prepared: get PET according to weight portion and cut into slices 90 parts, with step 2) modifier prepared mixes, and stir, then modified polyester fibre prepared by melt spinning.
The invention also discloses the bedding utilizing above-mentioned modified polyester fibre to be formed by weaving, comprise sheet, quilt cover and pillow cover.
The beneficial effect that the present invention obtains mainly comprises: traditional Chinese medicine ingredients compatibility of the present invention is reasonable, and preparation method is unique, and its modified fiber materials can effectively for neurasthenic auxiliary curing; Adopt glycerin monostearate and hydroxyethylcellulose can be coupled on polyster fibre by the active ingredient bonding in Chinese medical concrete, avoid the defects such as drug ingedient easily comes off and fabric color turns to be yellow, feel is hardened; The shitosan that the present invention selects can form void structure, is embedded wherein by other additives, and the carbonized titanium powder of selection can be used for improving mechanical strength, and improves health care.
