Description

Technical Field

[0001] The invention relates to the technical field of fabrics, and in particular to a moisture-absorbing and breathable chemical fiber fabric containing fine-denier polyester filaments and a production process thereof. Background Art

[0002] Moisture-absorbing and breathable chemical fiber fabrics containing fine-denier polyester filaments are a type of chemical fiber fabrics made with fine-denier polyester filaments as the key component through a specific production process. The process includes careful selection of the proportion of raw materials, such as adding an appropriate amount of hygroscopic fiber, and undergoing spinning, weaving, and finishing processes including moisture-absorbing, breathable, and softening treatments, so that the fabric has good moisture-absorbing and breathable properties and can be widely used in clothing and other fields.

[0003] After searching, the applicant found that a Chinese patent disclosed "a camel hair skin-friendly warm clothing fabric and its production process", and its publication (announcement) number is "CN115782318B". This patent mainly combines the corresponding nano-silver modified silk and special-shaped composite fiber yarns into the bottom layer and the velvet layer during weaving, so that the antibacterial modification of the fabric can be achieved through the composite camel hair silk yarn, and the special-shaped composite fiber yarns can improve the air flow and moisture absorption effect through the special-shaped grooves on the surface, effectively improving the antibacterial and moisture absorption capacity, and by coating the surface of the special-shaped composite fiber yarns with a protective liquid, the overall bonding strength of the camel hair fabric embryo can be improved, and the tensile resistance and anti-friction effects can be improved, thereby reducing the preservation effect affected by subsequent fabric pilling. However, this patent cannot resist the damage of ultraviolet rays to human skin, and it cannot produce a warming effect in cold weather to increase the temperature of the human body. For this reason, we propose a moisture-absorbing and breathable chemical fiber fabric containing fine-denier polyester filaments and its production process. Summary of the invention

[0004] The purpose of the present invention is to provide a moisture-absorbing and breathable chemical fiber fabric containing fine-denier polyester filaments and its production process, so as to solve the problem that the above-mentioned background technology cannot resist the damage of ultraviolet rays to human skin, and cannot produce a warming effect to increase the temperature of the human body in cold weather.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a moisture-absorbing and breathable chemical fiber fabric containing fine-denier polyester filaments, comprising fine-denier polyester filaments, moisture-absorbing fibers, antibacterial fibers, anti-ultraviolet fibers, far-infrared fibers and flame-retardant fibers. The fine-denier polyester filaments are selected from polyester filaments with a fineness between 0.5-1.5D (denier), and the moisture-absorbing fibers are modal fibers, which are adjusted according to the specific use of the fabric and the moisture absorption performance requirements.

[0006] As a further solution of the present invention, the proportion of the fine denier polyester filaments is 30% to 40%, and the fine denier polyester filaments are still the main component of the fabric, providing basic strength and a certain stability. The proportion of hygroscopic fibers is 20% to 30%, and hygroscopic fibers are essential for absorbing sweat generated during exercise.

[0007] As a further solution of the present invention, the proportion of the antibacterial fiber is 5% to 10%. In order to effectively inhibit the growth of bacteria, the proportion of the anti-ultraviolet fiber is 10% to 15%. For outdoor sportswear, anti-ultraviolet function is very important.

[0008] As a further solution of the present invention, the proportion of the far-infrared fiber is 10% to 15%. After exercise or in a cold environment, the far-infrared fiber can produce a warming effect and promote blood circulation.

[0009] As a further solution of the present invention, the proportion of the flame retardant fiber is 5% to 10%. Considering the possible fire risk in sports scenes, flame retardant fiber is added to improve safety.

[0010] In addition, the present invention also provides a production process of a moisture-absorbing and breathable chemical fiber fabric containing fine-denier polyester filaments, comprising the following steps: S1. Raw material selection: Choose polyester filaments with a fineness between 0.5-1.5D (denier). Fibers of this fineness can give the fabric a delicate feel and good drape. At the same time, ensure that the physical properties of the filaments, such as strength and elongation, meet the requirements of fabric production to ensure the stability of the fabric during subsequent processing and use; S2. Auxiliary fiber selection: In order to further optimize the performance of the fabric, a certain proportion of moisture-absorbing fiber, antibacterial fiber, anti-ultraviolet fiber, far-infrared fiber and flame-retardant fiber will be added; S3, blending process, blending fine mesh polyester filament with selected auxiliary fibers, using compact spinning or siro spinning technology to improve the strength and uniformity of the yarn; S4. Yarn quality control, strict quality inspection of blended yarn; S5. Fabric structure design: According to the purpose and performance requirements of the fabric, choose plain, twill or satin structure, or use honeycomb and openwork structure to increase the air permeability of the fabric; S6, weaving parameter adjustment, adjusting the parameters of the weaving machine, including warp tension, weft tension, opening time and weft insertion speed; S7, moisture-absorbing and breathable finishing, use special moisture-absorbing and breathable finishing agent to treat the fabric, the amount of finishing agent is 3% to 5% of the fabric weight; S8, Softening finishing: In order to improve the feel of the fabric, a softening finishing process is carried out, and silicone softener is selected, and its dosage is 1% to 2% of the fabric weight; S9, shaping treatment, shaping treatment is carried out on the finished fabric to stabilize the size and shape of the fabric and improve the flatness and appearance quality of the fabric.

[0011] As a further scheme of the present invention, in the blending process of S3, it is necessary to ensure that the various fibers are evenly distributed to avoid the phenomenon of fiber agglomeration, which affects the performance consistency of the fabric. By optimizing the parameters such as the roller spacing, drafting multiple and twist of the spinning machine, the fine-mesh polyester filament and the auxiliary fiber can be closely combined to form a blended yarn with good performance. The S4 includes strength, yarn uniformity and hairiness index indicators to ensure that the strength of the yarn reaches a certain standard and the breaking strength is between 15-20cN / tex to ensure the stability of the fabric during subsequent processing and use. The CV value of yarn uniformity is controlled within 10% to avoid defects in the fabric due to uneven yarn thickness. The hairiness index is controlled at a low level to reduce the surface of the fabric. The hairiness of the surface is improved to improve the smoothness and wearing comfort of the fabric. In the S5, for sportswear fabrics, honeycomb tissue is used, and its unique structure can form air channels to enhance the breathability of the fabric. For underwear fabrics, plain weave can be selected to ensure the softness and fit of the fabric. At the same time, through reasonable warp and weft yarn density design, the fabric is ensured to have certain moisture absorption and breathability. In the S6, the warp yarn tension is controlled between 100-150g, and the weft yarn tension is controlled between 80-120g to ensure the flatness and tightness of the fabric. The opening time and weft insertion speed are optimized according to the characteristics of the yarn and the fabric structure to avoid weft shrinkage, warp yarn breakage and weft yarn breakage, thereby ensuring the smooth progress of the weaving process and the stability of the fabric quality.

[0012] As a further solution of the present invention, in S7, the finishing agent is uniformly attached to the surface of the fabric fiber through processes such as padding and baking to form a hydrophilic film to enhance the moisture absorption and breathability of the fabric. In S8, the softener is infiltrated into the fiber through padding or dipping to reduce the friction coefficient between the fibers, making the fabric softer and smoother and improving the wearing comfort. In S9, the setting temperature is between 160-180°C and the time is 30-60 seconds, which is appropriately adjusted according to the fabric structure and fiber composition. During the setting process, the tension and shrinkage of the fabric must be controlled to ensure that the dimensional stability of the fabric meets national standards and customer requirements.

[0013] Technical effects and advantages of the present invention: The fine denier polyester filaments are selected to have a fineness between 0.5-1.5D (denier). Fibers of this fineness can give the fabric a delicate feel and good drape. The hygroscopic fibers are set to enhance the overall moisture absorption capacity of the fabric due to their high hydrophilicity, forming complementary advantages with the fine denier polyester filaments. The antibacterial fibers are set to inhibit the growth and reproduction of microorganisms such as bacteria and fungi. Adding silver ion antibacterial fibers to the fabric can effectively reduce problems such as odor and skin infection caused by the growth of microorganisms. The anti-ultraviolet fibers are set to absorb and reflect ultraviolet rays. When this fiber is used in fabric production, it can effectively reduce the damage of ultraviolet rays to human skin. The far-infrared fibers are set to absorb the heat emitted by the human body and radiate back to the human skin in the form of far-infrared rays to produce a warming effect. The flame-retardant fibers are set to prevent the spread of flames when encountering a fire source, thereby improving the flame-retardant properties of the fabric and ensuring the safety of users. By adopting advanced blending technology to mix fine-denier polyester filaments with hygroscopic fibers, the fibers are arranged tightly and evenly in the yarn, which improves the strength and evenness of the yarn. By strictly testing the strength, evenness and hairiness index of the blended yarn, the durability of the fabric during weaving and wearing is guaranteed, the yarn thickness is uniform, defects are avoided, the hairiness on the surface of the fabric is reduced, and the smoothness and feel of the fabric are improved; By selecting the appropriate fabric structure according to the purpose and performance requirements of the fabric to balance the air permeability, strength and feel of the fabric, and accurately adjusting the warp tension, weft tension, opening time and weft insertion speed of the weaving machine, the smooth weaving process and the stability of the fabric quality are guaranteed.

[0014] Through the post-finishing process, the fabric is post-finished with a special moisture-absorbing and breathable finishing agent to improve the fabric's ability to absorb and diffuse moisture and air. Softeners are selected to reduce the friction coefficient between fibers, making the fabric softer and smoother, and improving wearing comfort. The finished fabric is pre-shrunk to allow the fabric to shrink in advance to a certain extent to ensure its dimensional stability and meet the requirements of clothing production and wearing. Shape finishing is performed to ensure that the dimensional stability of the fabric meets national standards and customer requirements, while giving the fabric a good appearance style and wearing performance.
