Abstract
The invention relates to a composite treatment process of a wet spun linen yarn, belonging to the technical field of linen treatment. The composite treatment process is characterized by adopting composite treatment of the spun linen yarn and comprises the following steps: firstly carrying out NaOH/urea solution modified treatment, then carrying out acid washing and water washing, then carrying out laccase/acidic xylanase composite treatment and finally carrying out inactivation with boiling water, water washing and drying. The process has the effects of better removing gum reducing the rigidity and improving the yarn evenness.
Description
Technical field
The present invention relates to a kind of technique, especially relate to the composite treatment process of a kind of linen wet-spun yarn, it belongs to Caulis et Folium Lini processing technology field.
Background technology
The styles such as it is good that sodolin has sucting wet air permeability, comfortable and easy to wear nice and cool, well-pressed nature, more and more by consumers.Present Domestic jute mill uses wet spinning resultant yarn mode mostly, and routine can spin 16-50 Nm, not only becomes yarn count low, and yarn rigidity is big, and filoplume is more, and bar evenness is poor；Make it that quality problems such as broken end and cloth cover broken hole easily to occur in winder and weaving process, seriously constrain the range of application of linen thread and yarn.
Publication date is on 09 02nd, 2015, in the Chinese patent of Publication No. 104878489A, discloses the patent of invention of a kind of entitled " a kind of scribbled and preparation method thereof ".The processing technology of this patent scribbled is: the pretreatment of specialty fibers, specialty fibers and ramie stripes makes flaxen fiber bar, combing obtains rove bar, boil drift, wet spinning, the excision of yarn defect, before wet spinning, optionally make dyeing or openpore.Although the wool type blended fabric any surface finish that this technique obtains, very expansion are ventilative, Sweat Exhaust & Moisture Conductivity performance is good, but becomes yarn count low, and yarn rigidity is big, and filoplume is more, and bar evenness is poor；Make it that quality problems such as broken end and cloth cover broken hole easily to occur in winder and weaving process, seriously constrain the range of application of linen thread and yarn, therefore it still exists drawbacks described above.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency present in prior art, and a kind of rational technology is provided, first through NaOH/ urea liquid modification, again through laccase/acidic xylanase Combined Processing, it is that it is preferably removed colloid, reduces the composite treatment process of the linen wet-spun yarn of rigidity, raising bar evenness.
The present invention solves the problems referred to above and be the technical scheme is that employing Combined Processing lea yarn, applies concretely comprising the following steps in composite treatment process:
The composite treatment process of linen wet-spun yarn, it is characterised in that: use Combined Processing lea yarn, apply concretely comprising the following steps in composite treatment process.
(1) NaOH/ urea liquid is modified: use NaOH, CO (NH2)2And penetrating agent JFC, under the conditions of 85 DEG C, process 55min, bath raio 1: 10.
(2) pickling: use H2SO4, at room temperature processing 4 min, bath raio is 1: 20.
(3) washing: process 10min under normal temperature condition.
(4) laccase/acidic xylanase Combined Processing: use laccase and acidic xylanase, temperature 45 65 DEG C, time 90 180 min, pH value 5.0.
(5) boiling water inactivation: carry out making enzyme lose activity under boiling water treating, high temperature.
(6) washing: process 10min under normal temperature condition to totally.
(7) dry.
As preferably, in step of the present invention (1), the consumption of NaOH is 4% 9% (o.w.f), CO (NH2)2Consumption 3.5% (o.w.f), penetrating agent JFC
Consumption be 2% (o.w.f).
As preferably, H in step of the present invention (2)2SO4 'sMass concentration is 0.9 g/L.
As preferably, in step of the present invention (4), the consumption of laccase is 2.5% 5.5% (o.w.f), and the consumption of acidic xylanase is 2% 5% (o.w.f).
The present invention compared with prior art, has the following advantages and effect: 1, at NaOH, CO (NH2)2With under penetrating agent JFC effect, the colloid in linen thread and yarn is had certain swelling action, improves whiteness further；2, laccase and acidic xylanase Combined Processing can improve the performances such as the Unevenness CV value of line, capillary effect, elongation at break.
Detailed description of the invention
Below by embodiment, the present invention is described in further detail, and following example are explanation of the invention and the invention is not limited in following example.
Embodiment.
In the present embodiment, the composite treatment process of linen wet-spun yarn uses Combined Processing lea yarn, applies the detailed process in composite treatment process as follows.
The composite treatment process of linen wet-spun yarn, it is characterised in that: use Combined Processing lea yarn, apply comprising the following steps that in composite treatment process.
(1) NaOH/ urea liquid is modified: use the consumption of NaOH be 4% 9% (o.w.f), CO (
NH2)2Consumption 3.5% (o.w.f) and penetrating agent JFC 2% (o.w.f), under the conditions of 85 DEG C process 55min, bath raio 1: 10.
(2) pickling: use H2SO4Mass concentration 0.9 g/L, at room temperature process 4 min, bath raio is 1: 20.
(3) washing: process 10min under normal temperature condition.
(4) laccase/acidic xylanase Combined Processing: using the consumption that consumption is 2.5% 5.5% (o.w.f) and acidic xylanase of laccase is 2% 5% (o.w.f), temperature 45 65 DEG C, time 90 180 min, pH value 5.0.
(5) boiling water inactivation: carry out making enzyme lose activity under boiling water treating, high temperature.
