Description

Technical Field

[0001] The invention relates to a warp-knitted interlocking terry-like fabric and a production process, belonging to the technical field of textiles. Background Art

[0002] Terry fabric is a fabric covered with circular loops on one or both sides of the fabric. It has a soft feel, thick texture, good water absorption and warmth retention, and is often used in 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 formation mechanism. Compared with weft knitted terry fabric, warp knitted terry fabric is better in structural stability and terry uniformity; 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 fabrics in production efficiency. Therefore, warp knitted terry fabric has more development potential.

[0003] Traditional methods of weaving warp knitted terry fabrics include loop-dropping, weft-dropping and overfeeding. The overfeeding method forms loops by changing the warp feed amount of the combing bar. The loops formed by this method are affected by factors such as yarn tension, and it is difficult to control the height and uniformity of the loops. The loop-dropping and weft-dropping methods can only form loops on alternate coil arcs in each horizontal row, so the density of the loops formed is limited and the loops are not full enough. Summary of the invention

[0004]

Technical issues

[0005] The traditional warp knitting method for terry fabric has low production efficiency, difficult to control the height and uniformity of the terry, limited density of the terry, and insufficient fullness of the terry. A warp knitting method for producing fabric with high density of terry, full and uniform terry, and high production efficiency is needed.

[0006]

Technical solution

[0007] The first object of the present invention is to provide a production process for warp knitted interlocking imitation terry fabric, which adopts four comb bars for weaving, wherein the first comb bar GB1 weaves a warp plain structure, and in the even-numbered rows, the yarn is padded on the needles of the base fabric woven by GB3, and in the odd-numbered rows, the yarn is padded on the empty needles; the second comb bar GB2 weaves a weft insertion structure in the even-numbered rows, and the lateral movement direction of the needle back of the weft insertion comb is the same as the lateral movement direction of the needle back of the looping comb of GB1 in the even-numbered rows; GB2 weaves a looping structure in the odd-numbered rows; the third comb bar GB3 weaves a chain structure; and the fourth comb bar GB4 weaves a weft insertion structure.

[0008] When GB1 finishes weaving a row of odd-numbered rows and weaves the next even-numbered row, the yarn of the odd-numbered row falls off the needle to form a pile loop. Since the needle back lateral movement direction of the weft insertion comb of GB2 for the even-numbered rows is the same as the needle back lateral movement direction of the looping comb of GB1 for the even-numbered rows, the weft insertion will avoid the yarn. The original turning arc is clamped between the front comb loop and the extension line. Because of the avoidance, the turning arc of the weft insertion floats on the reverse side of the fabric process. Therefore, the number of pile loops produced by the process of the present invention is twice that of the conventional loop removal method and the weft removal method.

[0009] The terry weave formed by the odd-numbered rows of GB1 and the weft weave formed by the even-numbered rows of GB2 are entangled and interwoven to form an interlocking structure. The interlocking structure is protruding from the reverse side of the fabric process, which has a three-dimensional effect and decorative function.

[0010] The “first”, “second”, “third” and “fourth” are only used to distinguish similar components / parts with different positions or different characteristics and have no other limiting meanings; the “upper” refers to the direction of each component away from the ground, and the “lower” refers to the direction of each component away from the ground.

[0011] In one embodiment of the present invention, the production process of the warp knitted interlocking terry-like fabric comprises the steps of:

[0012] S1: material selection;

[0039] In one embodiment of the present invention, the application in the field of textiles includes application in cleaning cloths, towels, clothing, and household items.

[0040] Beneficial effects:

[0041] (1) The first combing bar GB1 of the present invention forms a terry structure in odd-numbered horizontal rows, and the second combing bar GB2 forms a weft-inserted structure in even-numbered horizontal rows. The terry structures are woven together to form an interlocking structure after the needle backs of the even-numbered horizontal rows move in the same direction as the first combing bar to avoid the yarn. Therefore, the process of the present invention produces twice as many terry loops as the conventional loop-dropping method and the weft-dropping method, and the terry loops are fuller and have a higher density.

[0042] (2) When GB1 and GB2 are made of ultrafine fibers, carbon fibers, and flax fibers with good cleaning properties and strong antibacterial properties, and GB3 and GB4 are made of high-strength, wear-resistant, and inexpensive chemical fiber filaments such as polyester and nylon, a warp-knitted interlocking terry-like fabric with a high number of terry loops on the reverse side of the fabric process can be produced. As a cleaning cloth or towel, it has a better cleaning and antibacterial effect in daily cleaning work. At the same time, the high-strength and wear-resistant fabric process on the reverse side plays a role in consolidation and deformation resistance, thereby improving the cleaning effect and increasing the service life of the cleaning cloth.

[0043] (3) The present invention utilizes the first combing bar GB1 to form a terry structure in odd-numbered horizontal rows, and utilizes the second combing bar GB2 to form a weft structure in even-numbered horizontal rows, which is then entangled and interwoven to form an interlocking structure and protrude from the reverse side of the fabric process to form a 3D shape with a decorative effect. At the same time, the first and second combing bars can change the number of the inlay yarns to form terry loops of different lengths, and can be matched with various fancy yarns to form a patterned effect.

[0044] (4) The first combing bar GB1 of the present invention forms a terry structure in odd horizontal rows, and the second combing bar GB2 forms a weft-inserted structure in even horizontal rows and forms a dodging yarn in the same direction as the needle back of the first combing bar in even horizontal rows, and then they are interwoven together to form an interlocking structure protruding on the back of the fabric; the chain-knitted structure of the third combing bar GB3 and the weft-inserted structure of the fourth combing bar GB4 are exposed on the front of the fabric to form a grid mesh structure. When GB1 and GB2 are made of comfortable, soft, and warm cotton yarn, modal, and acrylic, and when GB3 and GB4 are made of high-strength, wear-resistant polyester-cotton blended yarn, polyester, etc., the back of the fabric is warmer and more comfortable when in contact with the skin during daily wear, and the front of the process with a mesh effect has better heat dissipation and perspiration performance after human exercise. At the same time, the high-strength and wear-resistant yarn makes the fabric wear-resistant and not easy to deform during daily wear and washing. BRIEF DESCRIPTION OF THE DRAWINGS
