Description

Technical Field

[0001] This invention relates to the field of textile processing technology, specifically to a composite fabric with a cotton yarn and continuous basalt fiber wrapping structure and its preparation method. Background Technology

[0002] Cotton fiber is a major raw material in my country's textile industry, holding a very important position among textile fibers. my country is one of the world's major cotton producers, currently ranking among the world's top producers. Because cotton fiber is extracted from natural cotton plants, it possesses good moisture absorption, heat retention, alkali resistance, and hygiene, and is often used to make clothing. However, cotton fiber clothing also has certain drawbacks, such as relatively low strength, easy wrinkling, and difficulty in smoothing out wrinkles; it is also prone to shrinkage and deformation, especially after washing, where shrinkage is significant. To alleviate these shortcomings, cotton fiber is generally blended with other fibers during the production process, primarily natural fibers, chemical fibers, and animal fibers. The Central Institute of Cotton Fiber Technology (CIRCOT) in India has conducted specialized research on the blending of cotton fiber with other fiber materials. They discovered that blending special fiber materials such as hollow polyester fiber, trefoil fiber, and microfiber with cotton fiber can produce many practical fabrics with different functional properties. Therefore, many methods for blending cotton fiber have been developed.

[0003] However, in the application of textiles, there are some extreme conditions, such as high temperature, strong acid, and strong alkali corrosion, which place even more stringent requirements on the high temperature resistance and chemical stability of textile fabrics. Natural and chemical fibers are difficult to meet such application requirements. Therefore, people have explored blending cotton fibers with some metal fibers and inorganic fibers to obtain textile fabrics that are resistant to high temperature and acid and alkali corrosion.

[0004] Basalt continuous fiber is made from natural basalt ore, which is crushed and added to a melting furnace. It is produced through processes such as spinning and drawing in a molten state at 1400-1500℃. It produces no pollutants and is a natural, environmentally friendly fiber. Basalt fiber also possesses excellent mechanical properties, stable chemical properties, good dielectric properties, and high flame retardancy. Although inorganic fibers like basalt fiber have high temperature resistance and mechanical properties, their low elasticity and poor weaving properties make them difficult to use directly as clothing fabrics. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies and, considering the wearability and comfort of high-temperature resistant textile fabrics, to provide a composite fabric with a cotton yarn and continuous basalt fiber wrapping structure, along with its preparation method. This fabric is woven from a wrapped yarn obtained by combining continuous basalt fiber and cotton yarn, wherein the core yarn of the wrapped yarn is continuous basalt fiber, and the outer wrapping yarn is cotton yarn. The wrapped yarn combines the ease of weaving, water absorption, and soft hand feel of cotton fiber with the high strength, shrinkage-free properties, corrosion resistance, and high-temperature resistance of basalt fiber. This wrapped yarn fabric avoids direct contact between inorganic fibers and the human body, preventing punctures, while simultaneously improving the strength, shrinkage resistance, and wrinkle resistance of the cotton yarn. Garments made from this composite fabric have excellent wearability and comfort. The preparation method is simple, the production process is continuous, the production efficiency is high, the technology is easy to master, and it has great market potential. The developed fabric is expected to be widely adopted in the clothing industry.

[0006] The composite fabric of cotton yarn and continuous basalt fiber wrapping structure described in this invention is specifically operated according to the following steps:

[0007] a. Select continuous basalt fiber (1) with a diameter of 5-27μm as the core yarn of the wrapping yarn, and cotton yarn (2) as the outer yarn. Obtain the wrapping yarn by conventional wrapping method. The number of continuous basalt fiber (1) in the wrapping yarn is 50-800. The cotton yarn (2) includes ordinary yarn and / or combed yarn.

[0008] b. Take the wrapped yarn obtained in step a as a ply and twist it into a ply to obtain a composite yarn of basalt fiber (1) and cotton fiber.

[0009] c. The composite yarn obtained in step b is subjected to alkaline cooking and bleaching treatments sequentially to obtain the final composite yarn. The alkaline cooking involves placing the composite yarn in an alkaline cooking solution with a concentration of 10wt%-40wt%, setting the cooking pressure to standard atmospheric pressure, the cooking temperature to 80-120℃, and the cooking time to 60-100 minutes. The alkaline cooking solution includes one, two, or three of NaOH, ammonia, and Triton. The bleaching treatment involves placing the alkaline-cooked composite yarn in a bleaching solution with a concentration of 10wt%-30wt% for 60-120 minutes to obtain the treated composite yarn. The bleaching solution includes one, two, or three of NaClO, H2O2, and peroxyacid.

[0010] d. The composite yarn treated in step c is then soaked in an antistatic solution with a concentration of 0.5wt%-3wt%. The antistatic agent includes one or more of sulfonates, phosphates, chitosan, and quaternary ammonium salts. The treatment time is 10-30 minutes. Then, it is dehydrated and dried at a temperature of 80-120℃ to obtain the final composite yarn. The composite yarn is then woven to obtain a composite fabric with a cotton yarn and continuous basalt fiber wrapping structure.

[0015] b. Take the wrapped yarn obtained in step a as a ply and twist it into a ply to obtain a composite yarn of basalt fiber and cotton fiber;

[0016] Alkaline cooking-bleaching treatment:

[0017] c. The composite yarn obtained in step b is subjected to alkaline cooking and bleaching treatments sequentially to obtain the final composite yarn. The alkaline cooking involves placing the composite yarn in an alkaline cooking solution with a concentration of 10wt%-40wt%, setting the cooking pressure to standard atmospheric pressure, the cooking temperature to 80-120℃, and the cooking time to 60-100 minutes. The alkaline cooking solution includes one, two, or three of NaOH, ammonia, and Triton. The bleaching treatment involves placing the alkaline-cooked composite yarn in a bleaching solution with a concentration of 10wt%-30wt% for 60-120 minutes to obtain the treated composite yarn. The bleaching solution includes one, two, or three of NaClO, H2O2, and peroxyacid.

[0018] Antistatic treatment:

[0019] d. The composite yarn treated in step c is then soaked in an antistatic solution with a concentration of 0.5wt%-3wt%. The antistatic agent includes one, two, or three of the following: sulfonates, phosphates, chitosan, and quaternary ammonium salts. The treatment time is 10-30 minutes. Then, it is dehydrated and dried at a temperature of 80-120℃ to obtain the final composite yarn. The composite yarn is then woven to obtain a composite fabric with a cotton yarn and continuous basalt fiber wrapping structure.

[0020] Application of a composite fabric with a cotton yarn and basalt fiber wrapping structure in the preparation of high-temperature resistant protective clothing.

[0021] This invention provides a composite fabric with a cotton yarn and continuous basalt fiber wrapped structure and its preparation method. The method improves the blending method of basalt fiber and cotton fiber by using a wrapping method, with basalt fiber as the core and cotton yarn as the wrapping layer, to obtain a composite yarn with excellent moisture absorption, wrinkle resistance and high temperature resistance. The fabric woven from this yarn has excellent wearability and comfort, and is expected to be used in fields such as high temperature fireproof clothing. It also broadens the application range of basalt fiber and is of great significance.

[0022] Beneficial effects: The basalt fiber-wrapped composite fabric, its preparation method, and its application described in this invention have the following innovations compared to existing technologies:

[0023] 1. This invention combines the advantages of basalt fiber (high strength, high temperature resistance, no toxic gas emission, good heat insulation, and no heat shrinkage) with the advantages of cotton fiber (softness, moisture absorption, and ease of weaving) by blending basalt fiber with cotton fiber. In other words, by blending cotton fiber with basalt fiber, the spinnability of cotton fiber and the high strength of basalt fiber are organically combined, which greatly improves the wrinkle resistance, chemical corrosion resistance, flame retardancy, and heat insulation properties of cotton fiber fabric.

[0024] 2. This invention combines cotton yarn with basalt fiber through a wrapped yarn structure. This not only fully utilizes the excellent physical properties of basalt fiber, improving the overall physical and mechanical properties of the blended yarn, but also reduces the skin irritation of basalt fiber by wrapping the basalt fiber around the center of the yarn and using cotton fiber as a protective layer. Furthermore, in the clothing industry, basalt fiber replaces more chemical fibers, reducing the harm of chemical materials to human health and the environment.

[0025] 3. The preparation process of this invention is simple, the development cost is low, and it can realize the continuous preparation of materials, which has great market potential.
