Description
Technical field
The present invention relates to the boiling and bleaching process of the long numb spun yarn of the spinninging technical field in linen textile industry, especially flax.
Background technique
Flax is a kind of herbaceous plant, can be divided into fiber flax, oil seed flax and Oil and Fibre Flax three types.It is sub-
Fiber crops are the natural plant fibres that the mankind use earliest, since it is with absorbing sweat, good air permeability and harmless etc. significant special
Point, is increasingly paid attention to by the mankind.Pectin, half fiber of the flax other than containing cellulose, also containing connection flax single fiber
Dimension element and lignin, simultaneously containing some waxes, pigment, inorganic salts and ash content etc..The proper content pair of partial impurities in flax
The textile process of flax is advantageous, but the presence of most of impurity has seriously affected the processing of flax fiber and dress uses
Performance causes flax fiber dyefastness low, and colour purity is not high, and yarn rigidity is big and is easy to produce broken yarn.Flax fiber is thick
Firmly, dress creases easily, and feel is coarse, is extremely difficult to the unification of Dress Aesthetics habit and product inherent quality.Summary of the invention
The object of the present invention is to provide a kind of boiling and bleaching process combined for flax roving enzymatic treatment and sub- oxygen bleaching, which can
Guarantee stable product quality.
To achieve the purpose of the present invention, using following technical scheme.
A kind of boiling and bleaching process combined for flax roving enzymatic treatment and sub- oxygen bleaching, comprising the following steps:
(1) flax roving enzymatic treatment: flax roving immerses in soft water, is warming up to 55 DEG C, and potassium dihydrogen phosphate, bleeding agent is then added
JPK, soda ash, then plus alkali its pH is adjusted to 9.5, be eventually adding scouring enzyme and zytase, uniform circulation banked up 12 after 80 minutes
Hour；
(2) pickling: the concentrated sulfuric acid of scouring penetrant JPK and 93%-98% are added into soft water, is warming up to the speed of 1 DEG C/min
35 DEG C, pickling, drain after soak cycles 15 minutes are carried out to flax roving after mixing evenly；
(3) sub- drift: injection soft water, temperature are controlled at 30 DEG C, and the concentrated sulfuric acid of scouring penetrant JPK and 93-98% is added, and stirring is equal
After even, sub- drift material is added, sub- drift is started to flax roving, feed liquid circulation starts sub- drift after ten minutes, to flax roving, with 0.7
DEG C/speed of min is warming up to 45 DEG C of -48 DEG C of heat preservations 40-50 minutes, drain；
(4) it washes: the flax roving after sub- drift being washed with room temperature soft water, is exhausted after 10-15 minutes, then is with 50 DEG C soft
Water washing exhausts after 15 minutes；
(5) oxygen bleaching: with 30 DEG C of soft water, scouring penetrant, piece alkali, soda ash, chelated dispersants, hydrogen peroxide bleaching stabilizer, whiteness is added and increases
Into agent, after mixing evenly, oxygen bleaching material is added, recycles 10 minutes, oxygen bleaching is started to flax roving, is warming up to 85 with 0.8 DEG C/min
DEG C, drain after heat preservation 50 minutes；
(6) it washes: being warming up to 80 DEG C with soft water, drain in 15 minutes is washed to the flax roving heat preservation after oxygen bleaching；Successively added with 60 DEG C
Enter the soft water of chelated dispersants, softening agents are added in the soft water of 50 DEG C of addition glacial acetic acid and 40 DEG C and the soft water of post-finishing agent is washed
It washs, drain.
The sub- drift material is made of sodium chlorite, sodium nitrate and sub- drift stabilizer.
The oxygen bleaching material is made of hydrogen peroxide, sodium metasilicate.
Enzymatic treatment of the present invention and sub- oxygen bleaching combine, thus reduce the discharge of process spent water, reduce costs and
Under the premise of meeting spun yarn spinning process requirement, spinnability and Wu Si refer in particular to mark and are significantly improved.Overall process of the present invention is easy
In control, pollution-free, at low cost, stable product quality, the modern life of requirement and the green bast fibre spinning of low-carbon economy is also complied with
Theory, therefore the present invention has important theory significance and application value.
