Description
Technical Field
The invention belongs to the technical field of accessories of textile equipment, and relates to a loop-free sinker on a terry knitting machine.
The sinker of the terry loom is specially constructed, the nose of the sinker is lengthened, knitting is that a knitting needle firstly hooks the face yarn to start needle pressing, meanwhile, the sinker is pushed towards the cylinder center direction, the nose of the sinker supports the face yarn, and the knitting needle completes terry releasing after continuously pressing and hooking the ground yarn. An elongated sinker loop is formed on the surface of the fabric. However, due to different structures and triangular structures of the sinkers, the sinkers can hold the veil and the ground yarn in different manners, so that the difference that the ground yarn is exposed on the reverse side or wrapped in the middle is formed, and the sinkers are classified into positive wrapping machines and reverse wrapping machines. The height of the terry is mainly determined by the height of the nose, and the types of sinkers of the bale breaker are 1.8mm, 2.5mm, 2.9mm, 3.2mm and the like. The reverse packaging machine produces the high-grade velvet varieties, the ground does not expose the bottom, and the pile loop surface is sheared or napped to shake the grains.
Small patterns such as squares, vertical bars, etc. are usually woven on a reverse-lapping machine, where no loops are formed by a No. 0 sinker (no nose). The straight stripe pattern is generated by arranging sinkers with or without lugs on sinker rings, terry yarns on No. 0 sheets can only be padded on the sheets and synchronously looped with ground yarns to form concave-convex straight stripes on the surface of the fabric, and the straight stripes can also be matched with the horizontal stripes to act on the suede to form the required square effect.
A conventional No. 0 sheet on the market is selected, and the cloth surface debugged by cutting the sharp protruding part of the nose is poor, has a lot of exposed bottoms, is rough in hand feeling and is not soft. The analysis reason is as follows: in the initial state of the loom, the wool yarn is easy to partially form a loop at the nose tip root of the No. 0 sheet, and the nose root is easy to cut off the loop in the process of assisting the knitting needle to withdraw the loop and remove the sleeve when the sinker moves inwards. The cloth cover is exposed, so that the lattices are not clear and have no lattice effect.
Disclosure of Invention
The invention aims to provide a loop-free sinker on a terry knitting machine, aiming at solving the problems of the prior art, and the technical problem to be solved is how to make a fabric have no loops.
The purpose of the invention can be realized by the following technical scheme: the sinker without terry on the terry knitting machine is characterized by comprising a body, wherein a flat section jaw is arranged at the front end of the top of the body, a throat is arranged at the rear end of the flat section jaw, a nose root is arranged on the rear side above the throat, an inclination angle of 25-32 degrees is formed between the nose root and the flat section jaw, and the height of the throat is 0.5-0.8 mm.
Furthermore, an inclination angle of 30 degrees is formed between the root of the nose piece and the flat section jaw.
Furthermore, the throat is an arc-shaped curved part which is formed by inwards concave towards the rear side of the body.
Furthermore, the root of the throat and the root of the nose are in rounded transition.
The sinker purchased in the market does not leave a throat part, and the yarn laying angle of the ground yarn and the loop yarn cannot be controlled, so that the bottom exposure is caused; in addition, the included angle of the inclined plane is very critical, so that the synchronous loop withdrawing and looping of the ground yarns and the looped yarns are assisted, and looped yarns cannot be interfered to cause looped piles. The angle is controlled to be suitable at 30 degrees through repeated practice, so that the motion of the sinker can be better matched with the knitting needle, the cloth surfaces of the knitted straight strips and square blocks are not exposed, and the hand feeling is soft. The turning inclined plane of the throat part must be inverted into an arc shape to ensure the smoothness.
The engagement of the needles with the sinkers is crucial in weaving. From the motion curve of the sinker and the knitting needle in fig. 3, it can be seen that the sinker has two large thrusts, commonly called peak 1 and peak 2, and the radial positions of the sinker triangles in the two thrusts are analyzed below (the distance between the throat and the back line of the needle can be used to reflect the thrusting amount of the sinker). Peak 1: the sinker is advanced forward to place the ground yarn at the inner point of the hook near the needle bar and the inner side of the loop yarn, so that the ground yarn and the loop yarn are in correct relative positions. When the sinker is further pushed forward, the shoulder of the sinker is tensioned and the terry yarn of the previous row is tidied, but the terry yarn cannot be tidied excessively, otherwise, the terry yarn is broken or injured. The existing No. 0 sinker is not held by a throat, and the positions of ground yarns and looped yarns are changed to cause bottom exposure; in addition, when the sinker holding force and the loop pushing-out pressure are too small, insufficient loop withdrawal is likely to occur, and tuck defects are likely to occur in the fabric. The main reason for this problem is that the root of the nose forms a small loop at the loop yarn portion at peak 1; no. 0 sinker in this scheme has kept the throat, the relative position of ground yarn and terry yarn of control that can be fine. The root of the nose is inclined from the upper part of the throat to the upper right, and the terry yarn does not form terry at the position but forms plain base cloth together with the ground yarn. The sinkers purchased in the market do not leave tiger mouths (namely cambered surfaces formed by concave parts at throats), and the yarn laying angles of ground yarns and loop yarns cannot be controlled, so that bottoming is caused. Generally, the sinker cam is adjusted so that the distance between the throat and the back of the needle is between 0.50 and 0.70 mm.
Peak 2: is the key to weaving high quality terry fabrics. The sinker triangle is controlled by adjusting the coil, so that the bottom exposure phenomenon of the fabric can be overcome. Generally, the throat is preferably set to be 0.10 to 0.30mm from the back of the needle. When the peak 1 returns to the peak 2 to advance, the root of the nose of the 0 # sinker purchased in the market assists the knitting needle to retreat the ring and release the sleeve, so that the coil is easily cut off, the cloth cover is exposed, the grid is not clear, and the grid effect is avoided. No. 0 sinker in this scheme, the fin nose root falls into the inclined plane from the throat top to the upper right, and certain height H is left to throat department tiger's mouth, and H value control is between 0.5 ~ 0.8mm, and like this, the looped pile of preceding horizontal row can not be destroyed and play the effect of arrangement to preceding horizontal row to the inclined plane when the sinker is good at. Therefore, the included angle of the inclined plane is very critical, and is used for assisting the synchronous loop withdrawing and looping of the ground yarn and the looped yarn and assisting the looped pile finishing of the previous row. The angle is controlled to be suitable at 30 degrees through repeated practice, so that the motion of the sinker can be better matched with the knitting needle, the cloth surfaces of the knitted straight strips and square blocks are not exposed, and the hand feeling is soft. The transition point from the tiger's mouth to the inclined plane must be inverted into an arc shape, so that the smoothness is ensured.
Through the sinker, a series of small jacquard velvet products such as straight strips, square blocks and the like can be developed very successfully, and the sinker is popular in the market.

Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in figures 1 and 2, the device comprises a body 1, a flat section jaw 2 is arranged at the front end of the top of the body 1, a throat 3 is arranged at the rear end of the flat section jaw 2, a nose root part 4 is arranged at the rear side above the throat 3, an inclination angle of 25-32 degrees is formed between the nose root part 4 and the flat section jaw 2, and the height of the throat 3 is 0.5-0.8 mm.
Furthermore, the root part 4 of the nose piece and the flat section jaw 2 form an inclination angle of 30 degrees.
Further, the throat 3 is an arc-shaped curved portion formed to be concave inward toward the rear side of the body 1.
The root part 4 of the film nose is inverted into an inclined plane from the upper part of the throat 3 to the right upper part, a tiger mouth at the throat 3 is left with a certain height H, the H value is controlled to be between 0.5 and 0.8mm, and no tiger mouth is left on a sinker purchased in the market, which can not control the yarn laying angle of ground yarns and terry yarns so as to cause bottom exposure; in addition, the included angle of the inclined plane is very critical, so that the synchronous loop withdrawing and looping of the ground yarns and the looped yarns are assisted, and looped yarns cannot be interfered to cause looped piles. The angle is controlled to be suitable at 30 degrees through repeated practice, so that the motion of the sinker can be better matched with the knitting needle, the cloth surfaces of the knitted straight strips and square blocks are not exposed, and the hand feeling is soft. The tiger's mouth formed by the inclined plane which turns from the throat 3 to the root 4 of the nose must be inverted into an arc shape to ensure the smoothness.
The engagement of the needles with the sinkers 5 is crucial in the weaving. From the motion curve of the sinker and the knitting needle in fig. 3, it can be seen that the sinker has two large thrusts, commonly called peak 1 and peak 2, and the radial positions of the sinker triangles in the two thrusts are analyzed below (the distance between the throat and the back line of the needle can be used to reflect the thrusting amount of the sinker). Peak 1: the sinker 5 is advanced forward to place the ground yarn 7 at the inner point of the hook, near the shank portion and the inner side of the loop yarn 8, so that the ground yarn 7 and the loop yarn 8 are in the correct relative positions. When the sinker 5 is further pushed forward, the shoulder of the sinker 5 can be tensioned and the loop yarn of the previous row is finished, but the loop yarn cannot be finished excessively, otherwise the loop yarn is broken or injured. The existing No. 0 sinker is held without a throat, and the positions of ground yarns 7 and loop yarns 8 are changed to cause bottom exposure; in addition, when the sinker 5 holding force and the loop pushing-out pressure are too small, insufficient loop withdrawal is likely to occur, and tuck defects are likely to occur in the fabric. The main reason for this problem is that the root of the nose forms a small loop at the loop yarn portion at peak 1; no. 0 sinker in this scheme has kept the throat, the relative position of ground yarn and terry yarn of control that can be fine. The root of the nose is inclined from the upper part of the throat to the upper right, and the terry yarn does not form terry at the position but forms plain base cloth together with the ground yarn. The sinkers purchased in the market do not leave tiger mouths (namely cambered surfaces formed by concave parts at throats), and the yarn laying angles of ground yarns and loop yarns cannot be controlled, so that bottoming is caused. Generally, the sinker cam 6 is adjusted so that the distance between the throat and the back of the needle is between 0.50 and 0.70 mm.
Peak 2: is the key to weaving high quality terry fabrics. The sinker triangle is controlled by adjusting the coil, so that the bottom exposure phenomenon of the fabric can be overcome. Generally, the throat is preferably set to be 0.10 to 0.30mm from the back of the needle. When the peak 1 returns to the peak 2 to advance, the root of the nose of the 0 # sinker purchased in the market assists the knitting needle to retreat the ring and release the sleeve, so that the coil is easily cut off, the cloth cover is exposed, the grid is not clear, and the grid effect is avoided. No. 0 sinker in this scheme, the fin nose root falls into the inclined plane from the throat top to the upper right, and certain height H is left to throat department tiger's mouth, and H value control is between 0.5 ~ 0.8mm, and like this, the looped pile of preceding horizontal row can not be destroyed and play the effect of arrangement to preceding horizontal row to the inclined plane when the sinker is good at. Therefore, the included angle of the inclined plane is very critical, and is used for assisting the synchronous loop withdrawing and looping of the ground yarn and the looped yarn and assisting the looped pile finishing of the previous row. The angle is controlled to be suitable at 30 degrees through repeated practice, so that the motion of the sinker can be better matched with the knitting needle, the cloth surfaces of the knitted straight strips and square blocks are not exposed, and the hand feeling is soft. The transition point from the tiger's mouth to the inclined plane must be inverted into an arc shape, so that the smoothness is ensured.
