Description
Technical field
The utility model belongs to mechanical field, relates to a kind of tightening device for tensioning yarn.
Background technology
Yarn is the product being processed into certain fineness with various textile fibres, for weaving cotton cloth, rope making, line processed, knitting and embroidery etc.
Yarn is divided into: 1. staple yarn, is formed through spinning processing by chopped fiber (atural staple fibre or chemical fibre staple), divides ring spun yarn, open-end-spinning, certainly picks up yarn etc.2. continuous filament yarn, as natural silk and chemical-fibres filaments, point twist or not twist, smooth long filament or modified continuous filament etc.3. chopped fiber and continuous filament yarn combination yarn, such as polyester-cotton blend filament core-spun yarn etc.Line by more than two strands or two strands single thread and close twist and form.
The fineness of yarn has multiple method for expressing, such as number number, metric count, English count, danier etc. (see number).The twist of yarn represents with the number of picking up back of every meter or per inch.The direction of picking up back is divided S to pick up to pick up with Z.Within the scope of certain twist, the intensity twist of yarn increases and increases.Picking up of single thread is selected according to the purposes of strand to picking up of strand to collocation.Usual single thread and strand adopt contrary picking up to, i.e. ZS or SZ.The twist of single thread and strand has an optimum ratio, and within the scope of this, ply yarn stength increases along with strand twist and increases, and when exceeding critical value, ply yarn stength declines on the contrary.The proterties of fiber and the performance of Yarn spinning method to yarn play a decisive role.Ring spun yarn, in twist process, because fiber produces transfer, from yarn internal layer to skin, then from skin to internal layer, repeatedly shifts repeatedly, fiber around yarn axle center in the shape of a spiral, the radius of spin alternately increases vertically or reduces.At this moment the fiber that length is long more tends to the axle center of yarn, and the short fiber of length more tends to the skin of yarn.The axle center of the fiber trend yarn that fineness is thin, the skin of the fiber trend yarn that fineness is thick.The fiber that initial modulus is less is more positioned at skin, and the fiber that initial modulus is large is more positioned at internal layer.The fiber of reasonable selection various trait, can be spun into the yarn of different-style, adapts to different textile applications or improves wearability.Because chemical fibre can select arbitrarily the cross sectional shape of length, fineness and fiber, garment fabric should select the chemical fibre and cotton blending that fiber is slightly thick, length is slightly short, to increase the woolly aspect on resultant yarn surface.Underwear fabric should select the chemical fibre that fiber is slightly thin, length is slightly grown, and makes cotton fiber at the skin of yarn, to improve hygroscopic property and sense comfortable and easy to wear.Open-end-spinning comprises the yarn that air spinning, Static Spinning, vortex spinning etc. are spun into, and because fiber during twist inwardly shifts few, yarn core is compared with skin, tight inside but loose outside, loosely, Fiber Straightness is poor for structure, between fiber, cohesive force is poor, and yarn strength is low, but dyeability and wear resisting property good.From picking up the yarn that is spun into also known as certainly picking up yarn, being utilize stranding to pick up roller to produce periodically forward and reverse false twist degree to yarn, resultant yarn occurring thus brute force is lower, weaves after being generally plied to strand periodically without picking up a little again.
Filament yarn is by long filament (as natural silk, chemical fiber wire or rayon) and the thing of getting one's things ready be combined; Mainly contain polyester filament, viscose filament yarn, Tynex etc.
Fancy yarn main manifestations is the change in yarn appearance or color.Mainly contain looping, cored, ring, large tripe, color point, waveform, plait, towel, circle circle, knot, feather, toothbrush, centipede, belt, section dye, snow Neil etc.
The equipment arrived that above-mentioned yarn uses in manufacturing process is yarn machine, can not relax in manufacturing process for the ease of yarn, and people have devised various yarn tensioning mechanism.
Its publication number of Chinese patent CN104975415A provides " a kind of fabric thread tension device ", it comprises base, thread-carrier rod fixed leg, thread-carrier rod, yarn tensioning rod fixed leg, yarn tensioning rod loose slot, yarn steady ring and yarn tensioning rod.
Can find out, the thread tension device in above-mentioned patent, structure is simple, easy to use, and can ensure that yarn is subject to stable tension force, reduces the productive costs of fabric, improves the quality of fabric.
But said apparatus can not adjust due to tensile force, and for dissimilar yarn, it cannot be suitable for.
Other thread tension device existing also all also exists similar problem.
