Description

Technical Field

[0001] The invention relates to the technical field of fiber fabrics, and in particular to a degradable fiber fabric and a manufacturing method thereof. Background Art

[0002] Fiber fabrics are usually made of fibers through spinning, weaving and other processes. They can be made of a variety of fiber materials, including cotton, linen, silk, chemical fiber, etc. When making existing fiber fabrics, most of them need to disperse active powdered materials in matrix materials such as resin. Since most of the materials are wrapped in the matrix resin and cannot directly contact with the air and / or users, their activity is extremely low, resulting in material waste.

[0003] Prior art CN111254537A discloses a fiber-containing fabric and a preparation method thereof. Particle powder is added during the preparation of polyurethane fiber, and melt-mixing is performed to prepare the polyurethane fiber containing the particle powder. The particle powder is bonded to sodium lignin sulfonate and polyurethane raw material using polyurethane raw material as an adhesive. The particle powder can be firmly bonded to the fabric fiber through ring conjugation, hydrogen bonding and esterification, thereby fixing the particle powder on the fabric. At the same time, raw materials such as nano-silicon dioxide also play a role in providing particle activity, further contributing to the activity of the material, thereby avoiding the technical problems of affecting particle activity and particle loss during frequent washing that exist in fibers prepared by spraying or resin wrapping, resulting in failure.

[0004] However, the polyurethane fiber used in the preparation of the above-mentioned fiber fabrics is a high molecular polymer, which is difficult to degrade in nature, resulting in poor environmental protection of existing chemical fiber fabrics. It will bring microplastic pollution after use, thus causing great harm to the environment. Summary of the invention

[0005] The purpose of the present invention is to provide a degradable fiber fabric and a method for making the same, which solves the technical problem that the polyurethane fiber used in the preparation of existing fiber fabrics is a high molecular polymer and is difficult to degrade in nature, resulting in poor environmental protection of existing chemical fiber fabrics and causing microplastic pollution after use, thereby causing great harm to the environment.

[0006] To achieve the above object, the present invention provides a degradable fiber fabric, comprising the following components by weight: 10-25% natural fiber, 50-60% corn fiber, 10-20% degradable fiber, and the rest is bamboo charcoal fiber.

[0007] The natural fiber is one or more of wool fiber, silk fiber, cotton fiber and linen fiber.

[0008] Wherein, the degradable fiber is degradable plant fiber or polylactic acid fiber.

[0009] The present invention also provides a method for making a degradable fiber fabric, comprising the following steps:

[0010] Pretreating natural fiber, corn fiber, degradable fiber and bamboo charcoal fiber to obtain the pretreated natural fiber, corn fiber, degradable fiber and bamboo charcoal fiber;

[0011] The pretreated natural fiber, the corn fiber, the degradable fiber and the bamboo charcoal fiber are blended in proportion to form a fiber-wrapped yarn;

[0012] The fiber covered yarn is subjected to warping, weaving and dyeing and finishing processes in sequence to obtain the desired finished fiber fabric.

[0013] The specific steps of pretreating the natural fiber, corn fiber, degradable fiber and bamboo charcoal fiber to obtain the pretreated natural fiber, corn fiber, degradable fiber and bamboo charcoal fiber are as follows:

[0014] Firstly, the natural fiber, corn fiber, biodegradable fiber and bamboo charcoal fiber are removed from the fibers, mixed and rolled respectively;

[0015] Then, respectively decomposing the rolled fiber blocks of the natural fiber, the corn fiber, the degradable fiber and the bamboo charcoal fiber into single fiber states;

[0016] Secondly, the natural fiber, the corn fiber, the degradable fiber and the bamboo charcoal fiber are combined and drawn to form small rolls of specified length and weight;

[0017] Thirdly, the neps, impurities and fiber defects in the fiber are further removed, and after the removal, short fibers below a certain length are excluded;

[0018] Finally, the natural fiber, the corn fiber, the degradable fiber and the bamboo charcoal fiber are respectively stretched to a certain thickness to obtain natural fiber strips, corn fiber strips, degradable fiber strips and bamboo charcoal fiber strips.

[0019] The specific steps of blending the pretreated natural fiber, the corn fiber, the degradable fiber and the bamboo charcoal fiber in proportion to form the fiber-wrapped yarn are as follows:

[0020] Drawing, respectively stretching and thinning the natural fiber strips, the corn fiber strips, the degradable fiber strips and the bamboo charcoal fiber strips, mixing and forming them into strips;

[0021] coarse sand, respectively uniformly stretching the natural fiber strips, the corn fiber strips, the degradable fiber strips and the bamboo charcoal fiber strips after drawing, stretching and thinning, and twisting the stretched fiber strips;

[0022] Fine sand, respectively, drawing and twisting the twisted natural fiber strips, corn fiber strips, degradable fiber strips and bamboo charcoal fiber strips in sequence to obtain natural fiber yarns, corn fiber yarns, degradable fiber yarns and bamboo charcoal fiber yarns;

[0023] Winding, respectively winding and shaping the natural fiber yarn, corn fiber yarn, biodegradable fiber yarn and the bamboo charcoal fiber yarn to make bobbins, and removing defects and impurities on the yarns;

[0024] Twisting: twisting two or more single yarns of the natural fiber yarn, the corn fiber yarn, the degradable fiber yarn and the bamboo charcoal fiber yarn on the bobbin in proportion, and combining and twisting them to form fiber wrapped yarn.

[0025] The specific steps of sequentially performing warping, weaving and dyeing processes on the fiber-wrapped yarn to obtain the desired finished fiber fabric are:

[0026] The fiber yarns are warped in sequence to prepare for the subsequent weaving steps;

[0027] Weaving the fiber covered yarn after warping to form a double-sided structural fabric;

[0028] The fabric is treated with a hydrophilic pretreatment liquid and coated with a hydrophilic coating agent, and then subjected to a dyeing and finishing process to obtain a finished fabric.

[0029] The present invention discloses a degradable fiber fabric and a preparation method thereof. The fiber fabric is prepared by adopting natural fiber, corn fiber, degradable fiber and bamboo charcoal fiber. Since the natural fiber, corn fiber, degradable fiber and bamboo charcoal fiber are all degradable, the impact of the fabric on the environment can be reduced. By adding bamboo charcoal fiber and silk fiber to the fiber fabric, the prepared fabric is softer and more comfortable to wear. By adding polylactic acid fiber to the fiber fabric, the prepared fabric has high strength, good extensibility, soft hand feel, good drape and good resilience. The technical problem that the polyurethane fiber used in the preparation of the existing fiber fabric is a high molecular polymer and is difficult to degrade in nature, resulting in the poor environmental protection of the existing chemical fiber fabric in use, microplastic pollution after use, and thus causing great harm to the environment is solved.
