Abstract
The present invention relates to a kind of flax roving alkali process mercerization, it belongs to flax processing technology field.Flax roving is first carried out normal degumming and bleaching processing technology by the present invention, and then flax roving is carried out to the alkali process of high concentration again, finally rove is washed, and acid is neutralized and washes clean.Rationally, yarn is brighter and cleaner brighter, and soft yarns are significantly improved for present invention process, and dyeing color yield is improved, the problem of effectively solving hard yarn and low dye utilization rate.
Description
Technical field
The present invention relates to a kind of flax roving alkali process mercerization, the quality of line can be effectively improved, is particularly contaminated
Color coloured light, be it is a kind of normal degumming and bleaching technique is first carried out to flax roving, then carry out alkali process mercerising, be mainly used in Asia
The production of dimity spinning process, it belongs to flax processing technology field.
Background technology
Flax also has pectin, lignin and hemicellulose due to its special material composition in addition to cellulose in yarn
Presence, make line rough surface and filoplume many, have impact on the quality of yarn；Made simultaneously during follow-up dyeing process
It is low into color yield, the waste of the energy is not only caused, water harnessing is returned and brings difficulty.
Therefore it provides a kind of rational technology, further can be removed in flaxen fiber by alkali process again using rove after drift
The impurity such as pectin and hemicellulose, to improve the flexibility of yarn and the flax roving alkali process mercerization of dye uptake, it appears outstanding
For necessity.
Publication date is on 07 06th, 2016, in Publication No. 105734950A Chinese patent, discloses a kind of title
For the patent of invention of " flax roving peracetic acid bleaching process ".Flax roving is first carried out soda boiling processing by the patent, then will be thick
Yarn carries out acid treatment, then peracetic acid bleaching twice is carried out to the rove after acid treatment, and rove finally is washed into clean.Although this is special
Profit is small to fibre damage, and yarn strength is increased, and the numb particle of yarn has been reduced, but can not effectively solve that yarn is hard and dyestuff is sharp
With rate it is low the problem of, therefore still there is drawbacks described above in it.
The content of the invention
It is an object of the invention to overcome above shortcomings in the prior art, and a kind of rational technology is provided, environmental protection,
Yarn is brighter and cleaner brighter, and soft yarns are significantly improved, and dyeing color yield is improved, and can effectively solve that yarn is hard and dye utilization rate
Low flax roving alkali process mercerization.
The present invention the used technical scheme that solves the above problems is：The flax roving alkali process mercerization, its feature
It is：Apply concretely comprising the following steps in line spinning process：
（1）Degumming and bleaching：Flax roving is first subjected to normal degumming and bleaching technique；
（2）Alkali process：Using 95% alkali, handled 20 minutes under the conditions of 40 DEG C；Further to remove pectin in flaxen fiber etc.
Impurity, to improve the flexibility and dye uptake of yarn；
（3）Washing：Handled 15 minutes under the conditions of 50 DEG C；
（4）Washing：Handled 15 minutes under the conditions of 50 DEG C；
（5）Acid is neutralized：Using 96% acetic acid, handled 15 minutes under the conditions of 40 DEG C；
（6）Washing：Handled 10 minutes under normal temperature condition；
（7）Acid is neutralized：Using 96% acetic acid, handled 15 minutes under the conditions of 40 DEG C；
（8）Washing：10 minutes are handled under normal temperature condition to clean.
Preferably, step of the present invention（1）In, normal degumming and bleaching technique uses traditional sub- oxygen bleaching process.
Preferably, step of the present invention（2）In, the concentration of 95% alkali is 100g/L.
Preferably, step of the present invention（5）In, the concentration of 96% acetic acid is 4g/L.
Preferably, step of the present invention（7）In, the concentration of 96% acetic acid is 1.5g/L.
Preferably, it is 1 that alkali process of the present invention and acid, which are neutralized using bath raio,：10.
Preferably, the percentage of 95% alkali of the present invention and 96% acetic acid is weight percentage
The present invention compared with prior art, with advantages below and effect：1st, rational technology, yarn is brighter and cleaner, brighter；2nd, yarn
Flexibility is significantly improved；3rd, dyeing color yield is improved, and stocking yarn broken hole is substantially reduced.
Embodiment
Below by embodiment, the present invention is described in further detail, following examples be explanation of the invention and
The invention is not limited in following examples.
Embodiment.
In the present embodiment, by taking L36Nm as an example, flax roving alkali process mercerization is applied in line spinning process
In detailed process it is as follows.
（1）Degumming and bleaching：Flax roving is first subjected to normal degumming and bleaching technique；Normal degumming and bleaching technique is used
Traditional sub- oxygen bleaching process.
（2）Alkali process：Bath raio is 1：10, use concentration for 100g/L 95% alkali, 20 are handled under the conditions of 40 DEG C
Minute.
（3）Washing：Handled 15 minutes under the conditions of 50 DEG C.
（4）Washing：Handled 15 minutes under the conditions of 50 DEG C.
（5）Acid is neutralized：Bath raio is 1：10, concentration is used for 4g/L 96% acetic acid, and 15 points are handled under the conditions of 40 DEG C
Clock.
（6）Washing：Handled 10 minutes under normal temperature condition.
（7）Acid is neutralized：Bath raio is 1：10, use concentration for 1.5g/L 96% acetic acid, 15 are handled under the conditions of 40 DEG C
Minute.
（8）Washing：10 minutes are handled under normal temperature condition to clean.
The percentage of 95% alkali and 96% acetic acid in the present embodiment is weight percentage.
Flax roving is first carried out normal degumming and bleaching processing technology by the present embodiment；Then flax roving is subjected to height again
The alkali process of concentration, further to remove the impurity such as the pectin in flaxen fiber.To improve the flexibility and dye uptake of yarn；Finally will
Rove is washed, and acid is neutralized and washes clean.
Due to the characteristic of flax, the alkali of high concentration can effectively remove most of pectin and the hemicellulose in flax fiber,
The present embodiment can further remove the pectin and hemicellulose in flaxen fiber, so, yarn by alkali process again using rove after drift
Line of the line just compared with normal process is bright and clean, meanwhile, with the reduction of the impurity contents such as pectin, yarn seems more soft；It is another
Aspect, by the yarn of alkali process, dyeing tinctorial yield is significantly improved, dye utilization rate increase（Increase by 20% or so）, to environmental protection and life
Produce benefit all favourable.
Furthermore, it is necessary to explanation, the specific embodiment described in this specification, is named the shape of its parts and components
