Description
Technical field
The invention belongs to the acid bath method technical fields in production process of viscose fiber, and in particular to a kind of viscose glue is continuously spun
Acid bath groove band presses spinning process.
Background technique
Viscose rayon category regenerated celulose fibre, it is using native cellulose as raw material, through works such as alkalization, experienced, yellows
Soluble cellulose xanthate acid made of sequence, is re-dissolved in sig water and viscose glue is made, and is made through wet spinning.Raw material is starched first
Viscose glue stoste is made into the chemical machinings processes such as dipping, squeezing, crushing, experienced, yellow, dissolution are crossed in the dregs of rice, wherein mainly having
Cellulose alkalization and alkali cellulose yellow two chemical reactions；Viscose glue stoste sprays into acid bath by pore, makes wherein regeneration
And becoming the continuous strand of solid, the principal component of acid bath is sulfuric acid, additionally comprising substances such as sodium sulphate, zinc sulfate.Viscose glue is former
After liquid enters acid bath, free alkali in viscose glue is neutralized by acid, while sulfate plays strong dehydration to viscose glue, be allowed to solidify,
Cellulose is decomposited, and sulfate and carbon disulfide is precipitated.By fiber by washing, taking off when viscose rayon after acid bath is handled
Sulphur, bleaching, the basic working procedures such as pickling, oil, dry, and keeps strand pure and meets textile process needs.Traditional at present is continuous
Spin viscose filament yarn production method, acid bath groove be it is open, bucket is mainly balanced by acid bath and controls the one of acid bath groove liquid level
Cause property, flow velocity is lower in a glass tube for such method acid bath, and strand and acid bath relative velocity are big, is unfavorable for improving spinning speed.
Summary of the invention
The object of the present invention is to provide a kind of effectively to promote spinning rate in the case where guaranteeing that product quality is constant
Viscose glue continuously spins acid bath groove band pressure spinning process.
The present invention adopts the following technical scheme that achieve the above object, and a kind of viscose glue continuously spins acid bath groove band pressure spinning silk
Method, it is characterised in that detailed process are as follows: viscose glue stoste is sprayed into the acid bath in sealing acid bath groove by viscose glue pipe and spray head,
Viscose glue stoste forms with the acid bath hybrid reaction in sealing acid bath groove and in a glass tube with acid bath co-flow sustained response first
Raw silk item, sealing acid bath groove balance bucket by acid bath and continue feed flow, which balances bucket bottom liquid outlet and seal acid bath groove
Difference in height is 0.5-3 meters, for improving the flow velocity of acid bath in a glass tube by height fall, to reduce nascent strand and acid
The relative velocity of bath reduces nascent strand frictional force, and then improves viscose rayon in the case where guaranteeing that product quality is constant and spin
Silk speed.
Preferably, the hydrojet direction of the spray head is consistent with liquid flow direction in glass tube.
Preferably, the bottom end of the acid bath balance bucket is connect by acid bath inlet tube with the bottom end for sealing acid bath groove, acid bath
Balancing bucket bottom liquid outlet and sealing the difference in height of acid bath groove is 1.4-2.0 meters.
Preferably, the acid bath groove changes the open mode of traditional acid bath groove by the way of sealing.
Viscose glue provided by the invention continuously spins acid bath groove band pressure spinning process, can after improving to board equipment
To increase substantially spinning speed, in the case where guaranteeing that product quality is constant, single machine platform yield can be greatly improved, thus greatly
Width reduces production cost.The continuous spinning viscose filament yarn produced using the method for the present invention, finished product index and conventional spinning method are raw
The viscose rayon difference of production is little, does breaking strength 1.6-2.6cn/dtex, dry elongation at break 10%-20%.
Detailed description of the invention
Fig. 1 is that open acid bath groove and acid bath balance bucket position view in production process of viscose fiber before improving；
Fig. 2 is that sealing acid bath groove and acid bath balance bucket position view in production process of viscose fiber after improving.
In figure: 1- seals acid bath groove, and 2- acid bath balances bucket.
