Description

Technical Field

[0001] The invention relates to the technical field of flame-retardant textile fabrics, in particular to flame-retardant textile fabrics. Background Art

[0002] With the progress of society and the rapid development of science and technology, people have put forward higher and more diversified requirements on the performance of textile fabrics. Traditional textile fabrics have gradually exposed many shortcomings when facing some special scenarios and needs. In recent years, the public's safety awareness has been significantly improved, and flame retardant performance has become a key consideration for textile fabrics. In the fields of building interiors, vehicle interiors and various protective clothing, the demand for flame retardant textile fabrics has increased sharply. Therefore, work clothes with reliable flame retardant performance are needed to reduce the risk of fire at work.

[0003] Most of the existing textile fabrics are made of special fibers, which generally feel hard, greatly reducing the comfort of wearing. At the same time, most flame-retardant textile fabrics do not contain antibacterial materials. During use, bacteria will multiply in large numbers, causing the fabric to produce an unpleasant odor, affecting the wearing experience and the hygiene of the use environment. At the same time, it will decompose and destroy the fibers of the fabric, causing the strength of the fabric to decrease and the fibers to become brittle, thereby accelerating the aging of the fabric and shortening the service life of the fabric.

[0004] Therefore, in order to address the problem that the above-mentioned textile fabrics do not have antibacterial materials added, which affects the wearing experience and the sanitary conditions of the use environment, and at the same time causes decomposition and damage to the fibers of the fabrics, accelerates the aging of the fabrics, and shortens the service life of the fabrics, a flame-retardant textile fabric can be designed. Summary of the invention

[0005] In order to overcome the problem that antibacterial materials are not added to textile fabrics, which affects the wearing experience and the hygiene of the use environment, and at the same time causes decomposition and damage to the fibers of the fabric, accelerates the aging of the fabric, and shortens the service life of the fabric.

[0012] Preferably, the inorganic flame retardant includes aluminum hydroxide, magnesium hydroxide and expanded graphite, and other flame retardant additives include antimony trioxide and zinc borate.

[0013] The flame retardant textile fabric is prepared in the following steps:

[0014] Step 1: Yarn preparation: Aramid fiber and polyester fiber are uniformly mixed by mechanical stirring, titanium dioxide micropowder and antimony trioxide micropowder are added and stirred evenly during the mixing process to form a uniform cotton roll, and the cotton roll is placed in a carding machine to card the fiber into a single fiber state, so that the fiber is initially straightened and parallel;

[0015] Step 2: Combine multiple raw slivers together, pass through the roller drafting system to further straighten, parallelize and mix the fibers evenly, feed the raw slivers into the roving frame, and use the roller drafting device to thin the slivers to a certain degree, then use the spindle wing to twist the slivers to obtain a certain twist, feed the roving from the rear roller of the spinning frame, and pass through the roller drafting system to further thin it to the required linear density to form spun yarn;

[0017] Step 4: Mix the prepared hydrated compounds, immerse the woven fine sand in the prepared hydrated compounds solution, apply a certain pressure through the roller to allow the fabric to evenly absorb an appropriate amount of solution, and place the impregnated fabric in a dryer for drying.

At the same time, the water vapor generated during decomposition can dilute the oxygen concentration in the air to form a The combination of titanium dioxide micropowder and antimony trioxide micropowder can produce free radicals, destroy the cell wall and cell membrane of bacteria, achieve the effect of antibacterial disinfection, and effectively absorb ultraviolet rays to prevent ultraviolet rays from damaging human skin, protect fabric fibers from degradation by ultraviolet rays, and inhibit the generation of smoke to reduce the harm of smoke to the human body; through the mutual cooperation of the above materials, the flame retardant performance of the fabric can be significantly improved, the burning speed can be reduced, the spread of flames can be effectively prevented, the danger of fire can be reduced, and the infection caused by the breeding of microorganisms can be reduced, ultraviolet rays can be absorbed, the skin can be protected from sunburn and aging, the strength and wear resistance of the fabric can be improved, the fabric can be more durable, friction-resistant, not easy to break, and the service life of the fabric can be increased.
