Description

TECHNICAL FIELD

[0001] The present application relates to a paper yarn warp-knitted bark-imitating wrinkled fabric and a production process thereof, and belongs to the field of textiles. BACKGROUND

[0002] With the improvement of living standards, people's requirements for the beauty and comfort of clothing are getting higher, and monotonous plain fabrics are difficult to meet people's pursuit of fashion and beauty. Bark-imitating wrinkled fabric is a wrinkled fabric that imitates the surface morphology of tree bark, with irregular longitudinal and transverse stripes and irregular concave-convex wrinkles. The wrinkled fabric is knitted by warp knitting, and the elastic yarn is fed in the warp direction to knit the missing stitch organization. The elastic yarn shrinks to form single-sided convex wrinkles, and the process is complex. The main raw material of the wrinkled fabric yarn is chemical fiber filament, and the fabric hand is not rich enough, and the wearing comfort needs to be improved.

[0003] Paper yarn is a new type of yarn that uses lignin fiber as the main raw material. Paper yarn fabric products have a unique hand, better air permeability, moisture absorption and quick drying than cotton, and other advantages such as antibacterial and deodorant, no static electricity, natural and environmentally friendly. At present, paper yarn is mainly used to produce plain fabrics on flat knitting machines or circular knitting machines. However, pure paper yarn has the problems of low breaking strength and poor elasticity. Warp knitting is a common method of knitting fabric, which has a variety of organizations and can be combined with different mechanisms, equipment, knitting organizations and raw materials to design fabrics and develop fabrics with special structures. Compared with flat knitting machines and circular knitting machines, warp knitting machines have fewer restrictions on production efficiency and width. In the warp knitting process, only a few have low requirements for yarn performance, among which the full-width interlining warp knitting fabric can be knitted with paper yarn. However, the full-width interlining warp-knitted fabric is currently mainly used as an interlining in the industrial field or as a fabric for clothing, and is rarely developed as a directly used clothing fabric. SUMMARY

[0004]

Technical problem

[0005] At present, there are few wrinkled warp-knitted clothing fabrics on the market, and only single-sided convex wrinkles, and the weaving process is complex.

[0006] The main raw material of the wrinkled warp-knitted fabric is chemical fiber filament, and the fabric hand is not rich enough, and the wearing comfort needs to be improved. Paper yarn fabric has a unique hand, and has the advantages of moisture absorption, air permeability, and quick drying. However, pure paper yarn fabric has the problems of low breaking strength and poor elasticity.

[0007]

Technical solution

[0008] In order to solve the above problems, the present application provides a kind of paper yarn warp knitting imitating bark wrinkled fabric and production process. Specifically, with the full-width weft insertion mechanism of warp knitting machine, GB1 is woven with 20-100D yarn in the way of one-thread one-empty warp insertion, and chain stitch is adopted to make the fabric form clear vertical stripes; GB2 cooperates with GB1 to weave single needle weft insertion with 100-400D yarn in the way of certain change, so that part of the vertical stripes of the fabric is thickened; the parallel weft insertion mechanism MS1 inserts full-width weft insertion spandex core spun yarn or paper yarn in a certain rule, so that the fabric is shrunk in weft direction to form wrinkles. The chain stitch with empty warp insertion can imitate the longitudinal lines on the surface of tree bark, and the weft insertion with change makes the longitudinal lines change in thickness; the full-width weft insertion connects the chain stitches together to form a complete fabric. The spandex core spun yarn, which accounts for a small part, is limited in shrinkage due to part of the single needle weft insertion, and part of the core spun yarn accumulates to form protrusions. The paper yarn is also limited to form uneven protrusions, so that the front and back of the fabric form irregular wrinkles similar to the surface of tree bark, and the fabric has a certain elasticity in weft direction. The other part of the paper yarn will protrude with the shrinkage of the spandex core spun yarn, so that the fabric has the special hand feeling of paper fabric.

[0009] The first object of the present application is to provide a kind of paper yarn warp knitting imitating bark wrinkled fabric. The weaving structure of the fabric includes chain stitch, single needle weft insertion and full-width weft insertion. The chain stitch is woven with 20-100D yarn to form sparse and clear longitudinal stripes. The single needle weft insertion is woven with 100-400D yarn. The full-width weft insertion is woven with two kinds of yarn, spandex core spun yarn and paper yarn, which are inserted alternately in a certain rule. The full-width weft insertion connects the chain stitches together to form a complete fabric. The single needle weft insertion is woven on part of the chain stitches to thicken part of the chain stitches, and the combination of the chain stitch and the single needle weft insertion forms tight longitudinal stripes, which imitate the longitudinal lines of real tree bark, limit the shrinkage of the spandex core spun yarn in the full-width weft insertion, make the shrinkage of the spandex core spun yarn uneven, and form irregular wrinkled texture similar to tree bark. When the spandex core spun yarn shrinks, part of the paper yarn protrudes to the front or back of the fabric, so that the hand feeling of the fabric imitates the tree bark to a certain extent.

[0010] In an embodiment of the present application, the yarn used in the chain stitch is a chemical fiber filament selected from one or more of polyester and nylon.

The combination of the chain stitch and the single needle weft insertion stitch forms compact longitudinal stripes, which imitate the longitudinal lines of real bark and limit the shrinkage of the spandex core yarns in the full-width weft insertion stitch, so that the spandex core yarns shrink unevenly to form irregular wrinkled textures similar to bark. When the spandex core yarns shrink, the paper yarns partially protrude to the front or back of the fabric, so that the fabric hand imitates bark to a certain extent.

Advantages

[0037] (1) The paper yarn warp-knitted bumpy fabric imitating tree bark of the present application has the visual effect similar to the surface of tree bark on both the front and back sides. The present application forms the clear and varied longitudinal stripes imitating tree bark in the warp direction by using the suitable draft, the cooperation of two sets of warp-knitted stitches and the suitable yarn specification. The varied transverse stripes imitating tree bark are formed in the weft direction by using the full-width weft insertion stitch to alternately insert the spandex core-spun yarn and the paper yarn in a certain rule, and the spandex core-spun yarn is restricted by the chain of single needle insertion stitch when it shrinks, which makes the shrinkage of the spandex core-spun yarn uneven, resulting in the irregular wrinkle texture of the fabric. The combination of the varied horizontal and vertical stripes and the irregular wrinkle texture makes the visual effect of the fabric similar to the surface of tree bark.

[0038] (2) The paper yarn warp-knitted bumpy fabric imitating tree bark of the present application has the hand feeling effect similar to the surface of tree bark on both the front and back sides. The present application uses the paper yarn as the majority of the yarns for full-width weft insertion, and the paper yarn will not shrink when the spandex core-spun yarn shrinks, but will partially protrude to the front or back side of the fabric, which makes the fabric have the special hand feeling of paper yarn and realizes the hand feeling effect similar to the surface of tree bark.

[0039] (3) Through the yarn specification and the structure design of the fabric, the paper yarn warp-knitted bumpy fabric imitating tree bark of the present application has excellent breaking strength and a certain elongation in the weft direction. The problem of poor breaking strength and lack of elasticity of the existing pure paper yarn fabric is improved.

[0040] (4) The paper yarn warp-knitted bumpy fabric imitating tree bark of the present application uses paper yarn as the raw material, and the air permeability is significantly improved compared with the existing bumpy fabric.

[0041] (5) The paper yarn warp-knitted bumpy fabric imitating tree bark of the present application is manufactured by using common yarn materials, and the production method is simple and the production efficiency is high. BRIEF DESCRIPTION OF DRAWINGS

[0174] The tensile breaking property and air permeability of the fabric prepared in Example 1, Example 2, Example 3, Comparative Example 1 and Comparative Example 2 are measured, and the test results are shown in Table 6.

[0175] Table 6 Test results of examples and comparative examples

[0176]

[0177] As can be seen from the data in Table 6, the fabric prepared in Examples 1-3 has better tensile breaking performance and air permeability compared with Comparative Examples 1 and 2. Compared with Example 1, the fabric in Comparative Example 1 has poor strength and elongation in the weft direction and poor elasticity in the weft direction because there is no full-width laid-in weft yarn, so the fabric has no changing horizontal stripes and no shrinkage to form a creased texture. Compared with Example 1, the fabric in Comparative Example 2 has poor tensile breaking strength in the warp direction because there is only chain stitch and no laid-in weft stitch in the warp direction; the fabric has only fine vertical stripes with uniform thickness in the longitudinal direction and no restriction of laid-in weft yarn, so the shrinkage of the spandex core yarn is not restricted and no accumulated bulges are formed, and the creased texture of the fabric is relatively uniform.

[0178] The above provided examples are not intended to limit the scope covered by the present application, and the described steps are not intended to limit the execution order. The improvements of the present application made by those skilled in the art in combination with the existing common knowledge are also within the protection scope defined by the claims of the present application.
