Description

TECHNICAL FIELD

[0001] The present application relates to a warp interlocking imitation terry fabric and a production process, and belongs to the field of textile technology. BACKGROUND

[0002] Terry fabric is a fabric covered by looped stitches on one or both sides, which has soft hand feeling, thick texture, good water absorption and warmth retention, and is often applied in the fields of clothing, decoration and home textiles. Terry fabric can be divided into weft-knitted terry fabric, warp-knitted terry fabric and woven terry fabric according to the forming mechanism. Compared with weft-knitted terry fabric, warp-knitted terry fabric is more stable in structure and more uniform in terry; compared with woven terry fabric, warp-knitted terry fabric performs better in air permeability and softness, and is superior to weft-knitted and woven terry fabric in production efficiency, so warp-knitted terry fabric has more development potential.

[0003] The traditional warp-knitted terry fabric knitting method includes the knock-over method, the knock-out method and the overfeed method. The overfeed method forms terry by changing the feed amount of the guide bar. The terry formed by this method is difficult to control in height and uniformity due to the influence of factors such as yarn tension. The knock-over method and the knock-out method can only form terry on the loop arcs at intervals in each course, so the terry density is limited and the terry is not full enough. SUMMARY

[0004] TECHNICAL PROBLEM

[0005] The traditional warp-knitted terry fabric knitting method has low production efficiency, and it is difficult to control the terry height and uniformity. The terry density is limited and the terry is not full enough. A warp-knitted fabric production method with high terry density, full and uniform terry and high production efficiency is needed.

[0006] TECHNICAL SCHEME

[0007] The first object of the present application is to provide a production process of warp interlocking imitation terry fabric. Four guide bars are used for knitting. The first guide bar GB1 knits plain weave. In even courses, the yarn is laid on the needles of the base fabric knitted by GB3. In odd courses, the yarn is laid on the empty needles. The second guide bar GB2 knits weft insertion in even courses. The needle back of the weft insertion guide bar moves in the same direction as the needle back of the loop forming guide bar in even courses of GB1. GB2 knits loop formation in odd courses. The third guide bar GB3 knits chain stitch. The fourth guide bar GB4 knits weft insertion.

[0008] When GB1 weaves an odd-numbered course, the yarns of the odd-numbered course are dropped from the needles to form loops when the next even-numbered course is woven. Since the needle back transverse direction of the weft insertion comb of the GB2 even-numbered course is the same as the needle back transverse direction of the loop forming comb of the GB1 even-numbered course, the weft insertion will be evaded. The turning arc originally clamped between the front comb loop and the extension thread is floated on the reverse side of the fabric process due to the evading. Thus, the process of the present application produces twice as many loops as the conventional loop-dropping method and the weft-dropping method.

[0009] The loop structure formed by the GB1 odd-numbered course and the weft insertion structure formed by the GB2 even-numbered course are intertwined after evading to form an interlocking structure. The interlocking structure protrudes from the reverse side of the fabric process, has a three-dimensional effect and a decorative effect.

[0010] The terms "first", "second", "third", and "fourth" are only used to distinguish different positions or different features of the same components, and have no other limiting meanings; the term "upper" refers to the direction of each component away from the ground, and the term "lower" refers to the direction of each component away from the ground.

[0040] Beneficial effects:

[0041] (1) The first guide bar GB1 of the present application forms terry stitches in odd-numbered courses, the second guide bar GB2 forms weft stitches in even-numbered courses and interweaves with the even-numbered courses of the first guide bar in the same needle-back transverse direction to form an avoidance padding and then interweaves to form an interlocking structure, so that the number of terry stitches produced by the process of the present application is twice as many as that produced by the conventional knock-over method and weft-dropping method, the terry stitches are full and the terry stitch density is high.

[0042] (2) When the GB1 and GB2 are selected from superfine fibers, carbon fibers and linen fibers which have good cleaning properties and strong antibacterial properties, and the GB3 and GB4 are selected from polyester and nylon filaments which have high strength, good wear resistance and low price, a warp-knitted interlocking imitation terry fabric with high terry stitch density on the reverse side can be produced, which has better cleaning and antibacterial effects in daily cleaning work as a cleaning cloth or towel, and the high-strength and wear-resistant front side of the fabric plays a role in consolidating and resisting deformation, thereby improving the cleaning effect and increasing the service life of the cleaning cloth.

[0043] (3)The present application utilizes the first guide bar GB1 to form terry stitch in odd-numbered weft rows, and utilizes the second guide bar GB2 to form weft insertion stitch in even-numbered weft rows, and after avoiding the padding, the interlaced structure is formed, and protrudes from the reverse side of the fabric, and forms 3D stereoscopic shape, and has decorative effect; meanwhile, the first and second guide bars can change the padding number to form terry loops with different lengths, and meanwhile, various fancy yarns are matched to form pattern effect.

Claims

1. A production process for warp-knitted interlocking imitation terry cloth fabric, characterized in that, The fabric is woven using four guide bars. The first guide bar (GB1) weaves a plain weave, with the yarn placed on needles of the base fabric woven with GB3 in even-numbered rows and on empty needles in odd-numbered rows. The second guide bar (GB2) weaves a weft-inserting weave in even-numbered rows, with the needle backs of the weft-inserting guide moving in the same direction as the needle backs of the loop-forming guides in even-numbered rows of GB1. GB2 weaves a loop-forming weave in odd-numbered rows. The third guide bar (GB3) weaves a chain weave. The fourth guide bar (GB4) weaves a weft-inserting weave. When GB1 finishes knitting a row of odd-numbered rows, and the next row of even-numbered rows is knitted, the yarn of the odd-numbered row falls off the needle to form loops. Since the needle back of the GB2 even-numbered row weft insertion comb moves in the same direction as the needle back of the GB1 even-numbered row loop forming comb, the weft insertion will skip and pad the yarn. The original turning arc was sandwiched between the front comb loop and the extension line. Because of the skip, the turning arc of the weft insertion floats on the reverse side of the fabric process. The terry loop structure formed by odd-numbered rows of GB1 and the weft weft structure formed by even-numbered rows of GB2 intertwine together after avoiding the padding yarn to form an interlocking structure.
