A kind of colouring method of pure natural cotton fiber
Technical field
The present invention relates to textile dyestuff technical field, particularly relate to the dye of a kind of pure natural cotton fiber
Color method.
Background technology
In human history, natural fuel is made that indelible tribute for beautifying people's life
Offer.From 19 end of the centurys, due to developing rapidly of synthetic dyestuffs so that natural fuel base
Textile dyeing field has been exited on Ben.Along with constantly strengthening and to self of mankind's environmental consciousness
Healthy growing interest, partial synthesis dyestuff endangers produced by human health and ecological environment
More and more noticeable.Along with the raising of state-of-the-art, especially modern manufacturing industry level
Raising, safe, the health care of rag trade etc. is required the fastest more high by people, and natural dye is opened again
Begin to be paid attention to by people.In natural dye, animals and plants dyestuff is extracted by organism, with ring
The border compatibility is good, biodegradable.Natural dye is mostly Chinese medicine, in dyeing course, its
Medicine and flavor component are absorbed by fabric together with pigment, and in addition to dyeing function, natural dye is also
There is the several functions such as medicine, spice, make the medicine distinctive to human body of the fabric after dyeing protect
Health-care function.
Natural dye is during dyeing to fiber at present, in order to reach more preferable fabric
Color fastness, all can add some chemical assistants.
Caulis Sacchari sinensis is one of primary raw material of sugaring.Remaining bagasse after squeezing sugar, there are about
The fiber of 50% can be used to papermaking.But, part sugarcane marrow (myelocyte) is the most still had not have
Intertexture power, should remove before pulping process.Bagasse fibre length is about 0.65-2.17mm,
Width is 21-28 μm.Although its fibre morphology be less than timber and bamboo, but than rice,
Wheat straw fiber is the most slightly better.After slurry can allocate part wood pulp into, copy offset printing paper processed,
Cement bag paper etc..
Summary of the invention
In order to reach the Color without chemical assistant, the present invention provides a kind of pure natural cotton
The colouring method of fiber.
The colouring method of a kind of pure natural cotton fiber, comprises the following steps:
Step one: the pre-treatment of bagasse: rinsed well by bagasse raw material clear water, uses
30-50 DEG C of baking oven carries out drying and processing to bagasse, carries out the solid matter after drying repeatedly
After mechanical activation comminution 5-7 time, cross 25 mesh sieves, extracting screen underflow;
Step 2: the further ultrasonic grinding of bagasse by mechanical activation comminution is good: be molten with pure water
Agent, ultrasonic power is 500-800W, and solid-liquid ratio is the most ultrasonic under conditions of 1: 10-15
After ripple is pulverized 30-40 minute, filter, the filtrate of bagasse must be contained;Filtering residue after filtration is permissible
Continue ultrasonic grinding;
Step 3: by bagasse filtrate by decompression distillation and concentration, oven drying at low temperature, cross 600 mesh
Sieve, obtains bagasse micropowder;
Step 4: bagasse micropowder is put into natural dye concentrated solution high speed stirring 15-20
Minute, obtaining bagasse suspension, the solid content of described natural dye concentrated solution is 10-20%;
Step 5: added by carrageenan in bagasse suspension, stir, making viscosity is
The jelly of 2000-5000cps;
Step 6: be coated on cotton by jelly, described coating process parameter is: baking oven
Length 25-35 rice, 6 joint baking ovens, oven temperature is set to: 40 DEG C, 50 DEG C, 60 DEG C, 65 DEG C,
50 DEG C, 40 DEG C, machine speed is 10-15m/min, and rubberization thickness is 10-15 μm, is coated with during curling
Glue surface is covered with release paper;
Step 7: non-for cotton coated face is coated, parameter synchronization rapid six;
Step 8: after the release paper of the cotton of double spread being peeled off, be passed through the boiling water of 100 DEG C
In, wash 2-3 time, each 3-5min, i.e. can reach lasting Color.
Preferably, the solid content of the solid matter after drying in described step one is 50-70%.
Preferably, bagasse micropowder and the quality of natural dye concentrated solution in described step 4
Ratio is 1:10-40;
Preferably, described carrageenan is by the pure natural colloid extracted in plant.
Sieves in step one chooses 25 mesh sieves, and main purpose is to screen out foreign material.
Ultrasonic power in step 2 should not be the highest, the highest structure being easily destroyed bagasse, choosing
Take this power, both can promote the efficiency of ultrasonic extraction, it is also ensured that the structure of bagasse
Will not be destroyed.
In step 8, owing to carrageenan is substantially completely dissolved in water more than 80 DEG C, therefore use
The boiling water of 100 DEG C repeats all to be washed out by carrageenan for 2-3 time, for the bagasse fine powder of dyeing
It is partly submerged in cotton fiber, has reached lasting Color.
The Main Ingredients and Appearance of cotton fiber is cellulose, and cellulose is natural polymer, fiber
The chemical structural formula of element is that basic structural unit repeats to constitute by α glucose, and it is elementary composition is
Carbon 44.44%, hydrogen 6.17%, oxygen 49.39%.The degree of polymerization of cotton fiber is between 6000~11000.
Additionally, cotton fiber is accompanied by other materials of about 5%, referred to as accompaniment, accompaniment is to spinning
Yarn process and drift are practiced, dyeing and printing process all has an impact.Adipocere matter is contained on the surface of cotton fiber, is commonly called as
Cotton wax, cotton wax has protective effect to cotton fiber, is that cotton fiber has the former of good spinning performance
One of because of, but when high temperature, cotton wax easily melts.So cotton easily around roller, around rubber roll.
Through ungrease treatment, raw cotton hygroscopicity increases, and water absorbing capacity is up to 23~24 times of weight own.
The colouring method of pure natural cotton fiber provided by the present invention, uses bagasse and carrageenan
Cotton fiber is dyeed, completely without chemical assistant, can effectively cotton fiber be carried out
Dyeing, color fastness is good, bagasse can be carried out twice laid simultaneously, meet environmental protection
Manufacturing technique requirent.
