A kind of pretreatment of harl is at a device and method
Technical field
The present invention relates to a kind of pretreatments of harl into a device and method.
Background technology
Flaxen fiber only accounts for 20% or so with single fiber fractions distribution, remaining about 80% is glued at 10~40 to be a branch of It is present in bast together.After numb bast degumming processing, flaxen fiber for spinning is just of different thickness by these, length is different Fibre bundle and single fiber composition.Produced in bast fiber production technique out degummed ramie or the scutched line straightening of fibers depth of parallelism compared with Difference, and silk is serious, therefore be typically necessary and broken using opener, eckling machine, connection comb, gill box etc. and ramie stripes is made. Flaxen fiber is in carding process, due to needing to comb by the repeated multiple times strength of card wire, long fibre is pulled into staple fiber, because This generates a large amount of numb grain, and not only technological process is long, and fibre damage is serious, the bad control of fibre length, under average fiber length Drop, short fiber content increase, and the row yielding of ramie stripes only has 50% or so.
In existing flaxen fiber carding method, long fiber crops commonly use silk spinning circular comb equipment or device for dressing machine of ramie is combed through appropriate reconstruction At item, noil can be combed with cotton spinning equipment and be processed.The substantially combing of circular comb, the effect of combing process are to remove discomfort in ramie stripes The staple fiber of spinning requirement is answered, improves the length of fiber, regularity in product, and slightly increase long stapled content.Staple fiber Presence can largely effect on spinning performance, make drawing-off difficulty, evenness fault, strength reduce, broken end increase;Combing can also be more complete The impurity such as fibre defect and tiny hards, numb grain, hemp skin, waste of flax, runner are removed kindly, are reduced spun yarn and at yarn defect, are made fibre Dimension further increases extended parallelization in combing, is separated into thinner process of fiber, improves the bar evenness of ramie stripes, fiber Further mixed.The fiber that circular comb is produced is longer, and regularity is preferable, and a variety of yarns are can be directly used for after drafting combs Spinning.Device for dressing machine of ramie is conventional equipment, and point comb is abundant, thinner at process of fiber, but length is compared with short, difference is big, short fibre rate Generally 30% or more.Wet spinning carding process mainly uses the heckling machine of flax, and the long numb length that hackling is combed into is long, fineness is thin; Its noil is also slightly more much longer than circular comb noil, but noil amount is larger.Short fibre content is typically less than the short fibre of circular comb item and contains in hackling item The half of amount, and numb grain number is also less.
In short, no matter which kind of carding method can not all efficiently separate length in ramie stripes and thickness fiber in current device, Cause ramie stripes spinnability poor, spinning count is low, and yarn qualities are poor, and fiber utilization rate is low, to which production cost is high.
