A process for drawing and wrapping velvet

Abstract

The present invention relates to the technical field of weaving technology, and in particular to a process for drawing and wrapping velvet. The process is based on the use of two sinkers, which are divided into a first sinker and a second sinker. The jaw of the first sinker forms a horizontal flat section below the front end of the nose, and the front end of the nose of the second sinker is provided with a finishing section extending forward. The first sinker is driven by the first sinker corner track, and the second sinker is driven by the second sinker corner track; the first sinker and the second sinker are arranged in an interlaced manner. The process can realize velvet fabrics with a drawing effect and support pattern diversity. The terry finishing action of the second sinker, which retreats a distance and then moves forward after hanging the yarn, can solve the problem of bottom exposure and ensure the flatness and color consistency of the bottom fabric.

Description

Technical Field

[0001] The invention relates to the technical field of weaving technology, in particular to a process for drawing and wrapping velvet. Background Art

[0002] Existing terry fabrics are all woven in a dense weave method, that is, the surface is a dense upper layer of terry, and the bottom is a bottom layer of fabric. The pattern that can be formed by dense weaving is relatively simple. In order to increase the diversity of pattern shapes, there is a need on the market for a process that can achieve draw-out weaving, that is, a non-dense terry layer, so that there are draw-out sections of the upper terry where terry is not formed. From the appearance of the fabric, it can be seen that there are some formed terry and some unformed terry on the surface. If existing equipment is used for weaving, there are the following problems: at the position where terry is not formed, although the veil at this position is woven into the bottom layer of fabric, the veil at this position is relatively loose. The knitting needle will pull the veil downward during the subsequent up and down weaving process, which can easily cause the veil to pass through the bottom layer of fabric, resulting in the problem of the bottom layer being exposed, making the bottom layer fabric rough. In particular, when the veil and the bottom yarn are two different colors, the veil will slide under the bottom layer of fabric and expose the bottom, forming a spot of a different color, which affects the aesthetics. Summary of the Invention

[0003] In order to overcome the deficiencies in the prior art, the present invention provides a process for producing a velvet cloth by drawing strips and wrapping the velvet, which can realize a non-densely woven velvet loop layer and avoid the problem of the bottom being exposed.

[0004] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: a process for drawing and wrapping velvet, characterized in that: based on the use of two sinkers, the sinker includes a jaw, a nose is provided above the jaw, and a throat is formed between the nose and the jaw, and the sinker is divided into a first sinker and a second sinker, the jaw of the first sinker forms a horizontal flat section below the front end of the nose, and the front end of the nose of the second sinker is provided with a finishing section extending forward, and the top surface height of the finishing section is lower than the top surface height of the nose; the first sinker is driven by the first sinker corner track, and the second sinker is driven by the second sinker corner track;

[0005] A plurality of first sinkers arranged in series form a first sinker group, a plurality of second sinkers arranged in series form a second sinker group, each first sinker group is interspersed with each second sinker group, and the outermost first sinker of the first sinker group is adjacent to the outermost second sinker of the second sinker group, the face yarn passes through the sinkers at a position higher than the nose of the sheet, and the ground yarn passes through the sinkers at a position lower than the nose of the sheet;

[0006] At the first sinker: the knitting needle hooks the veil and presses it down, so that the veil is woven together with the bottom yarn at the horizontal section of the first sinker to form a bottom layer. Then the first sinker moves forward, so that the woven bottom layer enters the throat of the piece, and the knitting needle rises to complete the backing;

[0007] At the second sinker: the knitting needle hooks the veil and presses the needle downward, so that the upper part of the veil is hung on the nose of the second sinker to form an upper pile loop, and the lower part is woven together with the bottom yarn to be combined on the bottom tissue. The second sinker retreats a distance to make the looped veil fall into the finishing section, and then the second sinker moves forward a distance to push the looped veil forward and tighten it, and the veil that slides to the bottom tissue on both sides is pulled back into the bottom tissue, and at the same time, the woven bottom tissue enters the throat, and the knitting needle rises to complete the loop withdrawal.

[0008] Furthermore, the first sinker corner trajectory includes a first collecting segment, a first straightening segment, a first yarn hanging segment, and a first loop withdrawal segment arranged in sequence, and the second sinker corner trajectory includes a second collecting segment, a second straightening segment, a second yarn hanging segment, a finishing segment, and a second loop withdrawal segment arranged in sequence.

[0009] Furthermore, the first sinker corner trajectory and the second sinker corner trajectory are formed on the corner unit, and the corner unit includes a first sinker corner and a second sinker corner, and the first sinker corner and the second sinker corner are arranged in corresponding front and back positions, and the first sinker corner and the second sinker corner can be independently adjusted to the front and back positions, the first yarn hanging section and the first loop withdrawal section are arranged on the first sinker corner, and the second yarn hanging section, the finishing section, and the second loop withdrawal section are arranged on the second sinker corner.

[0010] Furthermore, when the first sinker is at the first yarn hanging section, compared with when the second sinker is at the second yarn hanging section, the nose end position of the first sinker is located behind the nose end position of the second sinker.

[0011] Furthermore, the corner unit also includes a third sinker corner, which is arranged on one side of the first sinker corner and the second sinker corner, and the first collecting segment, the first supporting segment, the second collecting segment, and the second supporting segment are arranged on the third sinker corner.

[0012] Furthermore, the first sinker group includes only one first sinker, and the second sinker group includes only one second sinker.

[0013] Furthermore, the first sinker group includes two or more first sinkers, and the second sinker group includes only one second sinker.

[0014] Furthermore, the first sinker group includes only one first sinker, and the second sinker group includes two or more second sinkers.

[0015] Furthermore, the first sinker group includes two or more first sinkers, and the second sinker group includes two or more second sinkers.

[0016] From the above description of the present invention, it can be seen that compared with the prior art, the present invention provides a process for making a strip-drawn and reverse-wrapped velvet cloth, which has the following advantages:

[0017] 1. This process can achieve velvet fabric with a drawing effect by interlacing the first sinker group and the second sinker group. By adjusting the number of first sinkers in the first sinker group and the number of second sinkers in the second sinker group, it can support the diversity of patterns.

[0018] 2. After the yarn is hung, the second sinker moves back a distance and then forward, which can push the looped yarn forward and tighten it, and pull the yarn that slides under the bottom fabric on both sides back into the bottom fabric, making the upper pile loops of the fabric uniform, solving the problem of bottom exposure, and ensuring the flatness and color consistency of the bottom fabric.

[0019] 3. The first sinker corner and the second sinker corner can be adjusted independently in front and back positions. Independent fine-tuning can meet the different position requirements of the first sinker and the second sinker when hanging yarn, thereby improving the accuracy of the equipment and thus improving the quality of the product.

DETAILED DESCRIPTION

[0026] The present invention is further described below through specific embodiments.

[0027] Reference Figures 1 to 5 As shown, a process for drawing and wrapping velvet is based on the use of two sinkers 1, the sinker 1 includes a jaw 11, a nose 12 is provided above the jaw 11, and a throat 13 is formed between the nose 12 and the jaw 11. The sinker 1 is divided into a first sinker 1a and a second sinker 1b. The jaw 11 of the first sinker 1a forms a horizontal flat section 14 below the front end of the nose 12 (refer to Figure 2 As shown); the front end of the nose 12 of the second sinker 1b is provided with a finishing section 15 extending forward, and the top surface height of the finishing section 15 is lower than the top surface height of the nose 12 (reference Figure 3 As shown); the first sinker 1a is driven by the first sinker hill corner track 2, and the second sinker 1b is driven by the second sinker hill corner track 3.

[0028] A plurality of first sinkers 1a arranged in series form a first sinker group, and a plurality of second sinkers 1b arranged in series form a second sinker group. Each first sinker group is interspersed with each second sinker group, and the outermost first sinker 1a of the first sinker group is adjacent to the outermost second sinker 1b of the second sinker group. The face yarn passes through the sinker 1 at a position higher than the sheet nose 12, and the ground yarn passes through the sinker 1 at a position lower than the sheet nose 12.

[0029] At the first sinker 1a: the knitting needle hooks the yarn and presses the needle downward, so that the yarn is woven together with the bottom yarn at the horizontal flat section 14 of the first sinker 1a to form a bottom layer structure, and then the first sinker 1a moves forward, so that the woven bottom layer structure enters the throat 13, and the knitting needle rises to complete the backloop.

[0030] At the second sinker 1b: the knitting needle hooks the yarn and presses the needle downward, so that the upper part of the yarn is hung on the nose 12 of the second sinker 1b to form an upper pile loop, and the lower part is woven together with the bottom yarn to be combined on the bottom tissue. The second sinker 1b retreats a distance so that the looped yarn falls into the finishing section 15, and then the second sinker 1b moves forward a distance so that the looped yarn is pushed forward and tightened, and the yarn on both sides that slides to the bottom of the bottom tissue is pulled back into the bottom tissue, and at the same time, the woven bottom tissue enters the throat 13, and the knitting needle rises to complete the loop withdrawal.

[0031] The first sinker corner track 2 includes a first collecting segment 21, a first straightening segment 22, a first yarn hanging segment 23, and a first loop-retracting segment 24 arranged in sequence, and the second sinker corner track 3 includes a second collecting segment 31, a second straightening segment 32, a second yarn hanging segment 33, a finishing segment 34, and a second loop-retracting segment 35 arranged in sequence.

[0032] The first sinker corner track 2 and the second sinker corner track 3 are formed on the corner unit. The corner unit includes a first sinker corner 4, a second sinker corner 5, and a third sinker corner 6. The first sinker corner 4 and the second sinker corner 5 are arranged in a front-to-back relationship and can be independently adjusted in front-to-back position. The first yarn hooking section 23 and the first loop withdrawal section 24 are located on the first sinker corner 4, while the second yarn hooking section 33, the finishing section 34, and the second loop withdrawal section 35 are located on the second sinker corner 5. The third sinker corner 6 is located on one side of the first sinker corner 4 and the second sinker corner 5. The first collecting section 21, the first supporting section 22, the second collecting section 31, and the second supporting section 32 are located on the third sinker corner 6.

[0033] When the first sinker 1a is at the first yarn hooking section 23, the end of the nose 12 of the first sinker 1a is located behind the end of the nose 12 of the second sinker 1b, compared to when the second sinker 1b is at the second yarn hooking section 33. (Refer to Figure 4 Figure 5 shown)

[0034] The present invention has multiple embodiments for the arrangement of the sinkers:

[0035] In the first embodiment, the first sinker group includes only one first sinker 1 a , and the second sinker group includes only one second sinker 1 b .

[0036] In the second embodiment, the first sinker group includes two or more first sinkers 1 a , and the second sinker group includes only one second sinker 1 b .

[0037] In the third embodiment, the first sinker group includes only one first sinker 1 a , and the second sinker group includes two or more second sinkers 1 b .

[0038] In the fourth embodiment, the first sinker group includes two or more first sinkers 1 a , and the second sinker group includes two or more second sinkers 1 b .

[0039] The specific working process of this kind of strip-drawing and reverse-wrapping velvet fabric process is as follows:

[0040] Taking Example 1, in which only one first sinker 1a is provided in the first sinker group and only one second sinker 1b is provided in the second sinker group as an example, that is, the first sinker 1a and the second sinker 1b are alternately arranged one by one to realize the interval drawing of corduroy fabric as an example, further detailed description is given.

[0041] In one weaving unit, the first sinker 1a and the second sinker 1b both pass through the third sinking horn 6 . The first sinker 1a passes through the first collecting segment 21 and the first stiffening segment 22 , and the second sinker 1b passes through the second collecting segment 31 and the second stiffening segment 32 .

[0042] The first sinker 1a passes through the first sinker corner 4: the first sinker 1a first passes through the first yarn hanging section 23, at which position the knitting needle hooks the face yarn and presses the needle downward, so that the face yarn is woven with the bottom yarn at the horizontal section 14 of the first sinker 1a to form a bottom layer structure; then the first sinker 1a passes through the first backing section 24, and the first sinker 1a moves forward a distance, so that the woven bottom layer structure enters the throat 13, and then the knitting needle rises. Since the bottom layer structure is confined in the throat 13, the knitting needle can complete the backing action.

[0043] The second sinker 1b passes through the second sinker corner 5: the second sinker 1b first passes through the second yarn hanging section 33, and the knitting needle at this position hooks the yarn and presses the needle downward, so that the upper part of the yarn is hung on the nose 12 of the second sinker 1b to form an upper pile loop, and the lower part is woven and combined with the bottom yarn on the bottom tissue; in the above steps: when the knitting needle moves downward to pull down the yarn, since the previous sinker 1 or the next sinker 1 is the first sinker 1a, its yarn is in a floating line state, which makes the yarn relatively loose, so it is possible to pull the front yarn down to pass through the bottom of the bottom tissue. Next, the second sinker 1b passes through the finishing section 15. At this time, the second sinker 1b will move backward a distance and then forward. When the second sinker 1b moves backward a distance, the looped yarn will fall into the finishing section 15. When the second sinker 1b moves forward, the looped yarn will be pushed forward and tightened. This action will cause the yarn that slides to the front or back side under the bottom layer to be pulled back into the bottom layer, solving the problem of bottom exposure. Finally, the second sinker 1b passes through the second backing section 35, and the knitted bottom layer enters the throat 13. Then the knitting needle rises. Since the bottom layer is confined in the throat 13, the knitting needle can complete the backing action.

[0044] Since the veil at the first sinker 1a needs to be hung on the horizontal section 14 in front of the sheet nose, the first sinker 1a needs to be in a relatively rear position in the first yarn hanging section 23 to ensure that the veil is hung on the horizontal section 14 and avoid the problem of the veil being mistakenly hung on the sheet nose 12 due to yarn deviation. Since the veil at the second sinker 1b needs to be hung on the sheet nose 12, the second sinker 1b needs to be in a relatively front position in the second yarn hanging section 33 to ensure that the veil is hung on the sheet nose 12. Therefore, the independently adjustable first sinker corner 4 and second sinker corner 5 are designed to meet the different position requirements of the first sinker 1a and the second sinker 1b through independent fine-tuning, thereby improving the accuracy of the equipment and thus improving the quality of the product.

[0045] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
