Abstract
The invention discloses a ramie quick degumming process in the production of high-quality sesame balls. The ramie quick degumming process comprises the following steps: ramie soaking: quick degumming dier boiling agent accounting for 1.0 weight percent to 1.5 weight percent of the ramie is used to soak the ramie for 1.0h to 1.5h at 50 DEG C to 60 DEG C; boiling at normal pressure: under the condition of normal pressure, 6g/l to 10g/l of NaOH aqueous solution is used to cook for 2h to 4h at 95 DEG C to 100 DEG C; the quick degumming dier boiling agent consists of gene improving alkaline pectase, stabilizer sodium acetate and magnesium chloride, penetrative emulsifier peregal O and trimeric sodium phosphate. The process shortens the technological process, and reduces the pickling procedure, so that the cellulose acidic hydrolysis probability is reduced and the degummed ramie forceful injury is small. The obtained degummed ramie has large break length and little hard thread doubling, is tender and applicable in spinning high grade cotton yarn.
Description
Technical field
The present invention relates to the preparation technology of a kind of ramie, specifically, the present invention is a kind of ramie fast degumming tech of producing high-quality numb ball.
Background technology
It is main and auxiliary chemical degumming technique with phosphate boiling-off auxiliary agent that China grass degumming is continued to use with the alkali lye boiling-off always, promptly utilize in the ramie raw ramie cellulose different to alkali, inorganic acid with the oxidant chemical stability with the colloid composition, by chemistry, mechanism, remove glue impurity component in the raw ramie, reach the purpose of coming unstuck entirely, obtain superior in quality degummed ramie.But drawbacks such as this technology exists, and technological process is long, energy consumption is big, wastewater discharge is big, pollution treatment cost height.
That " ramie yarn and thread production technology and the quality control " that Yu Chongwen, Zhang Yuanming, Jiang Fanchang write (publication of publishing house of China Textile University) discloses is a kind of " two boil one practices method ": unpack prick handle → pickling → washing → one and boil → wash → two boil → beat fibre → pickling → washing → dehydration → concise → washing → dehydration → oil supply → dehydration → oven dry.The characteristics of this technology are will be through twice soda boiling (mainly using NaOH) and once concise, and through repeatedly washing and dewatering.
Prior art adopts the degumming tech of the refining method of boiling based on two of soda boiling, and existing technology is produced the degummed ramie steady quality, is applicable to and spins middle coarse yarn that its shortcoming is:
1, existing process using two road high pressure boiling-offs, the energy consumption height;
2, kind, the quantity of existing technology labor and materials consumption are more, the cost of sewage disposal height.
Summary of the invention
In order to overcome these drawbacks, the purpose of this invention is to provide a kind of ramie fast degumming tech of producing high-quality numb ball.
In order to realize the foregoing invention purpose, the present invention by the following technical solutions:
A kind of ramie fast degumming tech of producing high-quality numb ball comprises following steps:
Bubble fiber crops: use the fast degumming scouring agent that accounts for numb gross weight 1.0～1.5wt%, steeped fiber crops 1.0～1.5 hours at 50～60 ℃;
The normal pressure boiling-off: under condition of normal pressure, with the NaOH aqueous solution of 6～10g/l, temperature is at 95～100 ℃, boiling-off 2～4 hours;
The fast degumming scouring agent is made up of gene modified alkaline pectase, stabilizing agent sodium acetate and magnesium chloride, infiltration emulsifying agent paregal O, sodium phosphate trimer, wherein, the gene modified alkaline pectase 60～65wt%, the sodium acetate that the account for the scouring agent gross weight 3～4wt%, the magnesium chloride that account for the scouring agent gross weight accounts for 1～1.5wt% of scouring agent gross weight, 18～20wt%, the surplus that infiltration emulsifying agent paregal O accounts for the scouring agent gross weight is sodium phosphate trimer.
The table 1 of this page is seen in the contrast of technology of the present invention and prior art.
The contrast of table 1 technology of the present invention and prior art
| Prior art degumming tech prescription | Degumming tech prescription of the present invention | |
| Pickling | H 2SO 43.0-3.5g/l temperature 60-65 ℃ of 2 hours time | |
| The bubble fiber crops | 50～60 ℃ of 1.0～1.5 hours times of fast degumming scouring agent 1.0～1.5% temperature | |
| One boils | II boils and reclaims buck glass 4% vapour pressure 2kg/cm 22 hours time | 95～100 ℃ of vapour pressures of NaOH 6～10g/l temperature; 2～4 hours normal pressure time |
| Two boil | NaOH 13g/l auxiliary agent 3% vapour pressure 2kg/cm 24 hours time |
The present invention has following advantage: the present invention has shortened technological process, reduces pickling procedure, and the acid hydrolysis probability of cellulose descends, disconnected long raising of degummed ramie.The degummed ramie of gained is disconnected to grow tall, the runner doubling is few, soft, is applicable to high-count yarn spun, can satisfy high-quality numb ball production requirement.
Specifically: adopt this technology, can shorten usually time more than 50%, reduce energy resource consumption 35%.(saved 20% and 50% respectively, by weight), the degummed ramie softness after coming unstuck is pure white to have saved steam and water consumption greatly, degummed ramie is disconnected long for more than 40km reaches, residual gum content is below 1.5%, and fibre count generally improves, reduce the doubling of degummed ramie runner (do the comb runner be lower than 60/10g).Improve the degummed ramie top-quality product rate, top-quality product rate reaches more than 90%, is higher than the top-quality product rate (80-85%) of prior art.
