[0002] Chemical fiber materials are important raw materials for modern textile industry. Among them, the chemical fiber materials with cotton-like effect are favored by consumers due to their good comfort and practicality. At present, the common cotton-like materials on the market are mainly polyester cotton-like materials. The polyester material has good strength and wear resistance, but its hand feeling is dry and rough, and the wearing comfort is general. SUMMARY

[0007] Technical solution three based on technical solution two: the first monofilament is networked to cover the second monofilament outside by a high-speed elasticizer, and the interval distance between adjacent network points is 1.5cm.

[0008] Technical solution four based on technical solution three: the mass fraction of the first monofilament in the covered yarn is 84%-86%, and the mass fraction of the second monofilament in the covered yarn is 14-16%.

[0009] Based on the technical solution four, the technical solution five is that the first monofilament and the second monofilament are formed by melt spinning of the polyamide material and the spandex material and then drawing, and the drawing multiple of the polyamide material is 1.03-1.07, and the drawing multiple of the spandex material is 2.8-3.3, so as to obtain corresponding fineness.

[0010] Based on the technical solution five, the technical solution six is that the first monofilament is a modified polyamide material by introducing hydrophilic groups into the polyamide fiber macromolecule by copolymerization.

[0011] In addition, the application also provides the technical solution seven, a preparation method of the cotton-like polyamide-spandex covered yarn, which is used for preparing the cotton-like polyamide-spandex covered yarn according to any one of the technical solutions one to six, and includes the following steps: melt spinning: the polyamide raw material and the spandex raw material are respectively melted and then extruded and spun; drawing: the monofilament of the polyamide material and the monofilament of the spandex material are respectively drawn, and the drawing multiple is respectively 1.03-1.07 and 2.8-3.3, so as to obtain the first monofilament with a fineness of 40D-70D and the second monofilament with a fineness of 20D-40D; network: the first monofilament is networked and covered outside the second monofilament, and the interval between adjacent network points is 1cm-2cm.

[0012] In addition, the application also provides the technical solution eight, a cotton-like micro-textured fabric, which is characterized in that the cotton-like polyamide-spandex covered yarn according to any one of the technical solutions one to six is woven and then subjected to high-temperature shrinkage treatment.

[0013] Based on the technical solution eight, the technical solution nine is that the high-temperature shrinkage treatment refers to treatment in a water environment or a steam environment at 100℃ for 15min-20min.

[0014] From the above description of the application, the application has the following beneficial effects compared with the prior art.

[0015] The application provides a cotton-like polyamide-spandex covered yarn, a preparation method of the covered yarn and a cotton-like micro-textured fabric woven from the covered yarn, wherein the covered yarn uses the first monofilament of the polyamide material as the outer covering fiber and the second monofilament of the spandex material as the inner core fiber, the polyamide material has high strength and durability, the spandex material has good elasticity and softness, and the covered yarn formed by the combination of the two has excellent resilience and good softness, the cotton-like micro-textured fabric woven from the covered yarn has good hand feeling and can effectively improve the wearing comfort of the cotton-like fabric.

[0016] The first monofilament, the second monofilament, the material, the fineness and the boiling water shrinkage are limited, and the size of the network points and the covering points in the covering yarn formed by the network covering of the first monofilament outside the second monofilament is limited, and the interval distance of adjacent network points is limited to 1cm-2cm. Through the limitation of these physical parameters, the monofilament with specific performance and the structure of the covering yarn formed after the network covering are synergistic, and the comprehensive performance of the covering yarn is improved. Specifically, the boiling water shrinkage of the first monofilament is slightly lower than that of the second monofilament, which makes the shrinkage degree of the first monofilament lower than that of the second monofilament in the fabric after high-temperature shrinkage treatment. The higher shrinkage degree of the second monofilament as the core fiber of the covering yarn makes the covering points in the covering yarn more fluffy, and the network points are also more compact. This has a synergistic effect with the structure feature that the network points and the covering points in the covering yarn are repeatedly arranged at intervals, so that the hand feeling of the covering yarn is more close to that of natural cotton fiber. In addition, the interval distance of the network points on the covering yarn is also closely related to the fineness and the boiling water shrinkage range of the monofilament, which ensures that the covering yarn has good uniformity and stability. Under the limited specific interval distance, fineness and boiling water shrinkage, the finally prepared fabric has a micro-muscle structure more close to that of natural cotton fabric.

[0017] In addition, the cross-sectional shape of the first monofilament is a rotational symmetric trilobal shape, which can increase the fiber surface area of the first monofilament, further improve the moisture absorption and dyeing performance of the fiber, and has the effect of being more close to natural cotton fiber. In addition, this shape design can make the network points and the second monofilament network more closely connected, and improve the imitation cotton hand feeling and the rebound performance of the covering yarn.

[0018] The first monofilament is networked and covered outside the second monofilament by a high-speed elasticizer, and the interval distance of adjacent network points is limited to 1.5cm. Under this distance, the covering yarn has good comprehensive performance.

[0019] The mass ratio of the first monofilament and the second monofilament in the covering yarn is limited, which optimizes the strength and the rebound performance of the covering yarn, so that the covering yarn has good durability and comfort.

[0020] The first monofilament and the second monofilament are formed after melt spinning and then drawing, and the draw ratio of the monofilament of the polyamide material is much smaller than that of the monofilament of the spandex material. The different draw ratios can not only obtain the first monofilament and the second monofilament with the required fineness, but also adjust the physical properties of the first monofilament and the second monofilament during the drawing process. The higher draw ratio makes the second monofilament have better resilience, and the lower draw ratio makes the second monofilament have higher strength. The setting of the draw ratios of the two is also closely related to the boiling water shrinkage of the two. Under the specific draw ratios and corresponding boiling water shrinkage, the cotton-like micro-texture of the fabric after high-temperature shrinkage treatment is more obvious, and the hand feeling is smoother.

[0021] The first monofilament is a modified polyamide material with hydrophilic groups introduced by copolymerization, which can improve the moisture absorption of the fiber, reduce static electricity, and improve the dyeing performance and softness. BRIEF DESCRIPTION OF DRAWINGS

[0031] In the claims, the specification, and the drawings of the present application, the terms "include", "have" and their variants are intended to mean "contain but not limited to".

[0032] Reference Figure 1 The present application provides a cotton-like brocade covered yarn, which comprises a first monofilament and a second monofilament, wherein the first monofilament is made of brocade material, the fineness is 40D-70D, and the boiling water shrinkage is 14%-18%; the second monofilament is made of spandex material, the fineness is 20D-40D, and the boiling water shrinkage is 15%-25%. The first monofilament and the second monofilament are both fibrous filaments, and the first monofilament is networked and covered outside the second monofilament to form the above-mentioned cotton-like brocade covered yarn. Moreover, the covered yarn repeatedly forms network points and covered points along its extension direction, the network points are formed by the first monofilament tightly covering the second monofilament, the covered points are formed by the first monofilament loosely covering the second monofilament, the interval distance between adjacent network points is the length of the covered points between them, and the interval distance is 1cm-2cm. Among them, as a preferred embodiment, the first monofilament is networked and covered outside the second monofilament by a high-speed elasticizer, and the interval distance between adjacent network points is 1.5cm.

[0033] In the cotton-like brocade covered yarn, the materials, fineness and boiling water shrinkage of the first monofilament and the second monofilament are limited, and the size of the network points and the covered points in the covered yarn formed by the network covering the second monofilament outside the first monofilament is limited, and the interval distance of adjacent network points is limited to 1-2 cm. Through the limitation of these physical parameters, the monofilament with specific performance and the structure of the covered yarn formed after network covering are synergistic, and the comprehensive performance of the covered yarn is improved. Specifically, the boiling water shrinkage of the first monofilament is slightly lower than that of the second monofilament, which makes the shrinkage degree of the first monofilament lower than that of the second monofilament in the fabric after high-temperature shrinkage treatment. The higher shrinkage degree of the second monofilament as the core fiber of the covered yarn makes the covered points in the covered yarn more fluffy, and the network points are also more compact. This has a synergistic effect with the structure feature that the network points and the covered points in the covered yarn are repeatedly arranged at intervals, so that the hand feeling of the covered yarn is more close to that of natural cotton fiber. And through the fluffy covered points, the surface area of the covered yarn is increased, so that the moisture absorption and dyeing performance of the covered yarn are improved. In addition, the interval distance of the network points on the covered yarn is also closely related to the fineness and the range of boiling water shrinkage of the monofilament, which ensures that the covered yarn has good uniformity and stability. Under the limited specific interval distance, fineness and boiling water shrinkage, the finally prepared fabric has a micro-muscle texture more close to that of natural cotton fabric.

[0034] In the cotton-like brocade covered yarn, the materials, fineness and boiling water shrinkage of the first monofilament and the second monofilament are limited, and the size of the network points and the covered points in the covered yarn formed by the network covering the second monofilament outside the first monofilament is limited, and the interval distance of adjacent network points is limited to 1-2 cm. Through the limitation of these physical parameters, the monofilament with specific performance and the structure of the covered yarn formed after network covering are synergistic, and the comprehensive performance of the covered yarn is improved. Specifically, the boiling water shrinkage of the first monofilament is slightly lower than that of the second monofilament, which makes the shrinkage degree of the first monofilament lower than that of the second monofilament in the fabric after high-temperature shrinkage treatment. The higher shrinkage degree of the second monofilament as the core fiber of the covered yarn makes the covered points in the covered yarn more fluffy, and the network points are also more compact. This has a synergistic effect with the structure feature that the network points and the covered points in the covered yarn are repeatedly arranged at intervals, so that the hand feeling of the covered yarn is more close to that of natural cotton fiber. And through the fluffy covered points, the surface area of the covered yarn is increased, so that the moisture absorption and dyeing performance of the covered yarn are improved. In addition, the interval distance of the network points on the covered yarn is also closely related to the fineness and the range of boiling water shrinkage of the monofilament, which ensures that the covered yarn has good uniformity and stability. Under the limited specific interval distance, fineness and boiling water shrinkage, the finally prepared fabric has a micro-muscle texture more close to that of natural cotton fabric.

[0035] The first monofilament and the second monofilament are formed by melt spinning and then drawing of a polyamide material and a spandex material. The polyamide material and the spandex material are added into an extruder to be uniformly melted, and then extruded through a spinneret. The spinneret for preparing the first monofilament has a specially designed trilobal shape, and the spinneret for preparing the second monofilament has a conventional circular shape. Specifically, referring to Figure 2 , the intersection between the outer wall of the first monofilament and a first plane perpendicular to the extension direction of the first monofilament is a trilobal shape with rotational symmetry, which includes three circular arcs with the same central angle and rotational symmetry around the center of the first monofilament. The end points of adjacent circular arcs are smoothly connected, and the convex directions of the three circular arcs point to the center of the first monofilament. This cross-sectional shape can increase the fiber surface area of the first monofilament, further improve the moisture absorption and dyeing performance of the fiber, and have a more natural cotton fiber effect. This shape design can make the network points of the covering yarn more closely connected with the second monofilament, thereby improving the cotton-like hand feeling and rebound performance of the covering yarn.

[0036] Meanwhile, the drawing ratio of the polyamide material monofilament is 1.03-1.07 times, and the drawing ratio of the spandex material monofilament is 2.8-3.3 times, so as to obtain corresponding fineness. The drawing of the materials can be performed by a ceramic twisting machine. Different drawing ratios can not only obtain the first monofilament and the second monofilament with desired fineness, but also adjust the physical properties of the first monofilament and the second monofilament during the drawing process. A higher drawing ratio makes the second monofilament have better rebound performance, and a lower drawing ratio makes the second monofilament have higher strength. The setting of the drawing ratios of the two monofilaments is also closely related to the boiling water shrinkage. Under the specific drawing ratios and corresponding boiling water shrinkage, the cotton-like microtexture of the fabric after high-temperature shrinkage treatment is more obvious, and the hand feeling is smoother.

[0037] In addition, the mass fraction of the first monofilament in the covering yarn is 84%-86%, and the mass fraction of the second monofilament in the covering yarn is 14-16%. The mass fractions of the first monofilament and the second monofilament in the covering yarn are limited, which optimizes the strength and rebound performance of the covering yarn, so that the covering yarn has good durability and comfort.

[0038] In addition, the application also provides a preparation method of the cotton-like polyamide-spandex covering yarn, which is used for preparing the cotton-like polyamide-spandex covering yarn and includes the following steps.

[0039] Step one, melt spinning: melt the polyamide raw material and the spandex raw material respectively, and then extrude and spin;

[0040] Step two, drawing: draw the monofilament of the polyamide material and the monofilament of the spandex material respectively, the drawing multiples are 1.03-1.07 times and 2.8-3.3 times respectively, the first monofilament with a fineness of 40D-70D and the second monofilament with a fineness of 20D-40D are obtained after drawing;

[0041] Step three, network: the first monofilament is wrapped on the second monofilament by using a high-speed elasticizer to form the wrapped yarn, the wrapped yarn repeatedly forms network points and wrapped points along the extension direction thereof, the network points are formed by tightly wrapping the second monofilament with the first monofilament, the wrapped points are formed by loosely wrapping the second monofilament with the first monofilament, the interval distance of adjacent network points is the length of the wrapped points therebetween, and the interval distance is 1cm-2cm.

[0042] In addition, the application further provides a cotton-like micro-textured fabric which is woven by the cotton-like polyamide-spandex wrapped yarn prepared above and is subjected to high-temperature shrinkage treatment. The high-temperature shrinkage treatment refers to treatment in a water environment or a steam environment at 100℃ for 15-20min.

[0043] The fabric woven by the cotton-like polyamide-spandex wrapped yarn and subjected to the high-temperature shrinkage treatment in a specific temperature environment has similar wrinkle micro-texture to cotton fiber fabric, high softness, good hand feeling and good wearing comfort.
