Description

Technical Field

[0001] The present invention belongs to the technical field of textile fabrics, and more specifically, relates to a fabric based on visualization and a production process thereof. Background Art

[0002] Functional fabrics are an important direction for the continuous development of textile technology, improving technological content and increasing added value, such as textile fabrics with self-heating function and textile fabrics with good softness and breathability. However, existing functional fabrics still have problems and cannot meet the needs of users. For example, textile products such as towels, bed sheets, and quilt covers need to be replaced regularly. Users cannot judge the performance and usage time of the fabrics by the naked eye, resulting in the inability to replace textile products within a reasonable time, breeding bacteria, and affecting the safety of users. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a visualization-based fabric and its production process, wherein the fabric can change color as the use time increases, so that the use time of the fabric can be visualized according to the color change, so that the user can replace the textile products made of the fabric in time, thereby avoiding the breeding of bacteria in the textile products and affecting the safety of the user.

[0004] One of the technical solutions of the present invention is a visualized fabric, comprising a visualized fabric body, wherein the fabric body is prepared by a visualized yarn through a jet weaving, a rapier weaving or a projectile weaving process; the visualized yarn comprises a core yarn and a covering layer wound outside the core yarn, wherein the covering layer comprises a polylactic acid fiber and a polyvinyl alcohol fiber group, wherein the weight ratio of the polylactic acid fiber to the covering layer is 20%.

[0005] -75%, and the weight ratio of the polyvinyl alcohol fiber group to the coating layer is 25%-80%.

[0006] Preferably, the color of the covering layer is different from the color of the core yarn.

[0007] Preferably, the polyvinyl alcohol fiber group includes three types of polyvinyl alcohol fibers, and the three types of polyvinyl alcohol fibers have different water-soluble temperatures.

[0008] Preferably, the water-soluble temperatures of the three types of polyvinyl alcohol fibers are 20° C., 40° C. and 80° C. respectively.

[0009] Preferably, the weight ratio of the polyvinyl alcohol fiber with a water-soluble temperature of 20°C to the polyethylene fiber group is 5%-15%, the weight ratio of the polyvinyl alcohol fiber with a water-soluble temperature of 40°C to the polyethylene fiber group is 60%-75%, and the weight ratio of the polyvinyl alcohol fiber with a water-soluble temperature of 80°C to the polyethylene fiber group is 10%-35%.

[0010] The second technical solution of the present invention is a production process of a fabric based on visualization, and the production process is an air jet weaving process, which specifically includes the following steps:

[0011] S1. Preparation of coating layer raw materials, preparing polylactic acid fibers with different colors from the core yarn and three types of polyvinyl alcohol fibers with different water-soluble temperatures through dyeing and color spinning processes;

[0012] S2. Preparation of the raw materials for the coating layer. According to the subsequent use environment of the visualization fabric, three polyvinyl alcohol fibers with different water-soluble temperatures are first mixed in weight proportion to obtain a polyvinyl alcohol fiber group, and then the polyvinyl alcohol fiber group and polylactic acid fiber are mixed again in weight proportion;

[0013] S3, yarn preparation, mixing the coating layer raw material prepared in step S2 with the core yarn, and then preparing a visualized yarn through a ring spinning process;

[0014] S4, fabric preparation, weaving the yarn prepared in step S3 through an air jet loom, a rapier loom or a projectile weaving machine to obtain a visualized fabric.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. A visualized yarn is obtained by wrapping a soluble or degradable coating layer around the core yarn. The visualized yarn is used to prepare a textile fabric by jet weaving, so that the color of the fabric changes with the increase of the use time, thereby realizing the visualization of the use time of the fabric.

[0017] 2. Through the visual design of the fabric, users can accurately judge the use time of the fabric according to the color change of the fabric, and replace the fabric product in time to avoid the fabric from being used for too long, breeding bacteria, causing infection, etc.

[0018] 3. According to the different usage environments and usage habits of the fabric products, the proportion of the coating layer fibers is precisely controlled, and the color change time of the fabric products is reasonably controlled to provide users with accurate fabric product performance status.

[0019] 4. The fabric can be combined with products to reflect the usage of the products through the color change of the fabric, which effectively solves the problem that some existing products need to rely on electronic equipment for timing, which is expensive and has low versatility.
