According to the present invention, loosening is performed, the flax cake is formed, alkali cooking degumming is performed, the flax cake is subjected to dehydration, drying and maintenance, the obtained flax cake is opened and then is sequentially subjected to linked combing, pre-needling, fine combing and post-needling, and finally the fine yarn is subjected to wet spinning to form the yarn; and the process has advantages o fiber splitting increasing, complete impurity removing, uniform color achieving, pre-spinning environment improving, and spinning yarn count increasing.
Description
Technical field
The present invention relates to a kind of spinning process, especially relate to and a kind ofly soda boiling is first carried out to second hards to come unstuck the new second hards raw yarn spinning process spinned again, be mainly used in the production of second hards raw yarn spinning process.
Background technology
Because scutching tow is short and impurity content is high, traditional spinning process be make after shredding, connection comb, grilling, combing, rear pin are first carried out to second hards rove again soda boiling come unstuck and be spun into linen thread and yarn; Because two slightly containing assorted high, although the series of processes before over-cooking drift is still containing a certain amount of numb skin, and soda boiling scouring processes can only remove a part of impurity such as pectin, lignin, very limited to the removal ability of numb skin, not only have impact on product quality, and the linen thread and yarn compared with high-count cannot be spun into.
Publication date is on November 24th, 2010, and publication number is in the Chinese patent of 101892535A, discloses the patent of invention that a kind of name is called " method of spinning medium-high count pure flax yarns by twain coarse fiber of flax ".This patent second hards staple fibre is main raw material, after mixed numb humidification, connection comb, two roads give pin, three times combing, four roads pin, rove, boil the techniques such as drift, spun yarn, drying, winder, the middle height be spun into props up pure flax yarn.Although this patent can reach the smooth exquisiteness of appearance of fabrics, reduce cost of material, add value-added content of product, but this patent makes rove soda boiling again after first carrying out shredding, connection comb, grilling, combing, rear pin, and the series of processes before over-cooking drift is still containing a certain amount of numb skin, and soda boiling scouring processes can only remove a part of impurity such as pectin, lignin, very limited to the removal ability of numb skin, not only have impact on product quality, and the linen thread and yarn that cannot be spun into compared with high-count, therefore still there is above-mentioned defect in it.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and provide one first to carry out soda boiling to come unstuck and carry out combing again, thus improve fiber division and thoroughly remove numb skin, look even, the new second hards raw yarn spinning process that quality is high.
The present invention's adopted technical scheme that solves the problem is: this new second hards raw yarn spinning process be applied to second hards raw yarn spinning process produce in concrete steps be.
(1) shredding form numb cake: second hards raw material is carried out on jute waste machine.
(2) soda boiling is come unstuck: bath raio 1:6, adopts 32% liquid caustic soda, bleeding agent Lun, chelating agent MC200 and sodium sulfite, under 95 DEG C of conditions, process 180 minutes, then 70 DEG C of hot water wash, and 50 DEG C of hot water wash, in an acetic acid, then it is clean to carry out twice washing.
(3) numb cake carried out dewater, dry, health: dewatering time is 60 minutes.
(4) the numb cake after health is opened, carry out connection comb, front pin, combing and rear pin successively, until rove.
(5) spun yarn wet spinning resultant yarn: rove is circulated 30 points in 40 DEG C of hot water.
As preferably, in step of the present invention (2), the working concentration of 32% liquid caustic soda is 15g/L, and the working concentration of bleeding agent Lun is 1g/L, and the working concentration of chelating agent MC200 is 0.8g/L, and the working concentration of sodium sulfite is 2g/L.
As preferably, in step of the present invention (2), the working concentration of acetic acid is 1g/L.
As preferably, dry in step of the present invention (3) and adopt radio frequency dryer to dry.
As preferably, the health in step of the present invention (3): to moisture 8%, namely the water giving humectant and 6.5% of 1.5%, sprays numb cake evenly, banks up more than 72 hours, then dry.
The present invention compared with prior art, has the following advantages and effect: 1. look even, and mix afterwards owing to adopting first to boil, color mixes; 2. spin environment before improving, particularly dust.3. because impurity elimination is abundant, then carried out health, flax fiber separation index is high, and soft yarns improves; 4. yarn evenness is even, Quality advance.Its quality is better than the yarn that machine cast tow is made, and cost of material reduces greatly; 5. can improve spun yarn number.
