Description
Technical field
The present invention relates to the spinning engineering field in the textile industry, be meant a kind of spinning method of fine spining machine.
Background technology
In recent years, spinning technique obtains fast development, and the special part equipment of novel spinning emerges in an endless stream, and has made positive contribution for improving yarn quality.Textile mills' use spun yarn press bar distance clip and two kinds of novel special parts of back zone additonal pressure rod are in the ascendant, wherein the spun yarn press bar distance clip is to set up pressure bar in last downside pin leading edge in the district of swimming of front roller nip, form curve drawing, in swimming the district, front draft sets up additional friction power circle, realized guaranteeing in the front draft zone the effective control of slow speed fiber to floating fiber, make it not do sth. in advance speed change, help improving bar evenness, the normal property faults of sending out such as minimizing is thick, details, cotton knot.Spun yarn back zone additonal pressure rod is to increase single pressure bar in V-type drawing-off back zone, can eliminate the reverse arc of contact that the top roller upper end face occurs, make the yarn behind the pressurized, when entering the middle top roller jaw, linearly reach flat form, eliminating the friction field width expands to draw zone, stop the unstable speed change of fiber and produced new hooked fibre, can make the rear roller surface increase by one section new grip hold arc after increasing pressure bar, strengthened control to the staple fibre motion, make the reach of floating fiber speed change point, do thereby improve into sliver.Install pressure bar additional and make the back zone produce additional friction power circle, help strengthening back zone drafting multiple,, realize that the rove amount of resetting technology lays the first stone for further bringing into play the spinning-drafting ability.
Above-described two kinds of spun yarn equipment can improve yarn quality, but still come with some shortcomings during independent the use:
When (1) independently using spun yarn proparea working pressure rod spacing block, the proparea produces additional friction power circle, control ability strengthens, if implement the rove amount of resetting technology, then the proparea drafting force increases, and the drawing-off irregularity improves, for relaxing fiber interphase interaction power, need to amplify roller gauge, amplify the spacing block specification, transfer big back zone drafting multiple, it is not obvious to cause yarn quality to improve like this, and applying pressure rod spacing block is worth little.Therefore, independent working pressure rod spacing block can not be realized the purpose of modern new cotton spinning equipment High-efficient Production.
When (2) independently using spun yarn back zone additonal pressure rod, increased the friction field intensity of back zone postmedian, strengthened in the drawing-off control for fiber movement, but when implementing the rove amount of resetting high efficient technology, for relaxing the proparea drafting force, need to implement to amplify back zone drafting multiple, amplifying the proparea spaces, reduce measures such as roving twist, and the proparea lacks the additional control to fiber, cause yarn quality as slightly, details, index such as cotton knot and filoplume is improved not obvious, when therefore using the additonal pressure rod separately, High-efficient Production can be realized, but the purpose that high-quality is produced can not be realized maximizing.
Summary of the invention
At above defective, the invention provides and can overcome above defective, can realize the High-efficient Production of fine spining machine, can realize the production method of heavy-weight and high-uniformity spun yarn that high-quality is produced again.
Technical scheme of the present invention is: the environment temperature in the spinning process is 18～34 ℃, relative humidity is 50～70%, fine spining machine configuration Pneuamtic cradle, V-type curve drawing device, soft elasticity high abrasion rubber roll and cushion rubber, press bar distance clip, back zone additonal pressure rod are adopted in fine spining machine draw zone proparea.
Proparea of the present invention working pressure rod spacing block and back zone additonal pressure rod utilize the two excellent specific property to fiber control, to realize the production of spinning high-efficiency high-quality.By improvement and adjustment, realized the combination that proparea press bar distance clip and back zone additonal pressure rod is used to existing spinning technology.The present invention is a kind of spun yarn spinning method, and the advantage that it uses for reference two kinds of equipment can realize both High-efficient Production of modern novel cotton spinning frame, and the purpose of high-quality production helps saving production cost again, helps improving added value of product.
In addition, the spacing distance of the roller that the spun yarn proparea is adjacent is 17.5～28mm, and the proparea nip gauge is 2.0mm～5.0mm.Be primarily aimed at different drafting multiples, friction field, sliver structure and fibre property, the proparea drafting force changes during spinning, for alleviating the big contradiction of proparea drafting force, proparea drafting force and front roller nip grasping force being adapted, can be by regulating the spacing distance and the nip gauge of roller, the realization drawing-off is normally carried out.
The spacing distance of the roller that the spun yarn back zone is adjacent is 20mm～50mm, and back zone drafting multiple is 1.25～1.45 times.Be primarily aimed at different drafting multiples, friction field, sliver structure and fibre property, proparea drafting force and back area draft power change during spinning, drawing-off is normal, the resultant yarn bar evenness is good and steady quality in order to make, can realize the suitable distribution of proparea drafting force and back area draft power by regulating the spacing distance and the back zone drafting multiple of back zone roller.
Preceding rubber roll is pressurised into 150～190N to roller.Be primarily aimed at different drafting multiples, friction field, sliver structure and fibre property, the proparea drafting force changes during spinning, for making front roller nip grasping force and proparea drafting force adapt, improve the resultant yarn bar evenness, rubber roll pressurizes to roller before can regulating, make front roller nip that pressurization heavier, that adapt be arranged, out of control to prevent drawing-off jaw gripping yarn, keep good normal drawing-off.
Spinning fiber quality length is 25～51mm.The present invention adapts to staple fibre, medium-length fibre is pure spins or blending production, has stronger fibre length and can spin suitability.
The spinning spindle rotating speed is 11000～20000r/min.Spinning suiting variety range of the present invention is wide, at different cultivars, can select different spinning spindle rotating speeds, to realize the high-speed production of spinning.
Regular roving feeding is 2.0g/10m～9.0g/10m.Spinning suiting variety range of the present invention is wide, at different cultivars, can select different regular roving feedings, to realize the High-efficient Production of spinning.
