Description

Technical Field

[0001] The invention relates to the technical field of fabrics, in particular to a multifunctional fabric that is UV-resistant, moisture-absorbing and quick-drying and a preparation method thereof. Background Art

[0002] In life, the fabric of clothes is the most important factor in determining the quality of a piece of clothing. Good clothing fabrics have good UV resistance and breathability. Faced with global warming and the impact of continued high temperatures in summer, consumers are increasingly demanding higher requirements for sun protection. In terms of physical sun protection, the traditional weft-knitted sun-protective fabrics can only achieve UPF50+ UV protection, which is far from meeting the sun protection needs of higher-end consumer groups. This will inevitably lead to the search for fabrics with higher UV protection indexes. If weft-knitted fabrics want good UV protection, the fabrics must be slightly thicker and a tight weaving method must be used to reduce the gaps between the yarns. After meeting the UV requirements, the fabrics will become airtight. If they want to be light and breathable, the UV protection will be poor. It is difficult to have both. At the same time, traditional fabrics have poor quick-drying performance and poor durability, which makes it difficult to meet the summer wearing experience.

[0003] In view of the above problems, a multifunctional fabric with UV resistance, moisture absorption and quick drying and a preparation method thereof are proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a multifunctional fabric that is anti-ultraviolet and moisture-absorbing and quick-drying and a preparation method thereof, which solves the background art requirements of being more breathable and quick-drying while meeting the user's requirements for ultraviolet protection.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a multifunctional fabric that is resistant to ultraviolet rays and absorbs moisture and dries quickly, comprising: nylon yarn and spandex yarn, the nylon yarn and spandex yarn are wound around each other to form a braided wire, the spandex yarn is 20D spandex yarn, the nylon yarn contains 65D / 48F nylon filament, titanium dioxide matting agent, sunscreen additive and super washable finishing additive, the nylon yarn and spandex yarn weigh 160 grams, the cross-section of the fabric is a cross-section special-shaped nylon, and multiple braided wires are divided into warp and weft respectively, and the warp and weft are woven together to form the fabric.

[0006] A method for preparing a multifunctional fabric that is UV-resistant and moisture-absorbing and quick-drying, comprising the following steps; S1. Select yarn, choose 65D / 48F nylon filament FDY yarn plus 20D spandex yarn combination for subsequent weaving; S2, yarn treatment, by adding enough titanium dioxide to the nylon yarn, the value is 3% of the total weight, the chemical formula is TiO2, commonly known as titanium dioxide, to make it fully matte yarn, and then adjust the length of the yarn to select the best ratio to reach 155 grams per square meter to resist ultraviolet rays, add sunscreen additives and super washable finishing additives to enhance its sunscreen effect and wear resistance; S3, weaving, when weaving, use thick yarn to expand the gap between the coils, and then use the high needle count of 36G to make the fabric more delicate; S4, dyeing, the woven fabric is dyed and fixed by a water recycling device, and then the fabric is discharged.

[0007] As a further description of the above technical solution: in the step S1, the thermal conductivity of nylon is 0.244-0.337, which is greater than the thermal conductivity of 0.084 of traditional polyester thread. The cool feeling is the temperature difference formed by the heat of the skin transferred to the low-temperature fabric when the human skin contacts the fabric, and the contact coolness coefficient is closely related to the thermal conductivity of the material. The higher the thermal conductivity, the higher the coolness at the moment of contact, so nylon yarn is selected.

[0008] As a further description of the above technical solution: in the step S1, the yarn in the FDY form is commonly known as fully drawn yarn, and the yarn shape is relatively straight, so the thermal conductivity is better than that of the traditional DTY.

[0009] As a further description of the above technical solution: in step S1, the water molecule conductivity of 65D / 48F nylon filament is better than that of traditional nylon filament.

[0010] As a further description of the above technical solution: in step S2, the unique cross-section of the 65D / 48F nylon filament can block the radiation of ultraviolet rays, and the addition of titanium dioxide can play a role in shielding ultraviolet rays.

[0011] As a further description of the above technical solution: In the step S3, the high needle count of 36G makes the fabric more delicate and does not make the vertical density too high when the weight is 160 grams, thereby maintaining a certain lightness and breathability.

[0012] As a further description of the above technical solution: in the step S4, the dyeing pool is cleaned with high-temperature hot water to keep it clean, the woven fabric is placed in the dyeing pool, dyeing agent is added, and water is added to the dyeing pool through a preparation box for dyeing. After dyeing is completed, the upper water is extracted and recovered, and the water and solidified materials at the bottom are drained, and then the dyed fabric is color matched. After the color matching is completed, water is added again and a fixing agent is added, and the water after color fixing is discharged into the treatment pool, and water is added for neutralization. After multiple times, the fabric is neutralized, and the last layer of water is pumped back into the preparation box before the fabric is discharged.

[0013] As a further description of the above technical solution: in the dyeing process, because the water recovered after dyeing is acidic, it can be used to adjust the acidity for subsequent use, thereby reducing the amount of acid used.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The invention provides a multifunctional fabric with UV resistance and moisture absorption and quick-drying and a preparation method. The thermal conductivity of the fabric is improved by selecting fully drawn yarn nylon with a better thermal conductivity coefficient, and the subsequent heat absorption and quick-drying effect is improved by selecting 65D / 48F nylon filaments. Special yarn filaments and 20D spandex are used to ensure that the weight is light and the fabric has a suitable density. Repeated comparative experiments are used to obtain the best weaving process and the application of a post-finishing sunscreen auxiliary agent. At the same time, the shielding effect of the titanium dioxide component in the full matte yarn is used to make the fabric have a very good UV protection effect. Special differentiated yarns are used in combination with super washable post-finishing auxiliary agents to ensure the excellent moisture absorption and quick-drying characteristics of the fabric. Water can be reused through a water circulation mechanism, and different water temperatures can better treat pollutants in sewage to maintain good environmental working requirements.

Choose 65D / 48F nylon filament FDY yarn plus 20D spandex yarn combination for subsequent weaving. The thermal conductivity of nylon is 0.244-0.337, which is greater than the 0.084 thermal conductivity of traditional polyester yarn. FDY yarn is commonly known as fully drawn yarn. The yarn shape is relatively straight, so the thermal conductivity is better than traditional DTY. The water molecule conductivity of 65D / 48F nylon filament is better than that of traditional nylon filament. Therefore, 65D / 48F nylon filament FDY yarn is selected.

[0020] S2. Yarn processing: by adding enough titanium dioxide to the nylon yarn, the value is 3% of the total weight, the chemical formula is TiO2, commonly known as titanium dioxide, to make it a fully matte yarn, and then adjust the length of the yarn to choose the best ratio to reach 155 grams per square meter to resist ultraviolet rays, add sunscreen additives and super washable finishing additives to enhance its sun protection and wear resistance; the unique cross-section of 65D / 48F nylon filament can block ultraviolet rays, and the addition of titanium dioxide can block ultraviolet rays.

[0021] S3. Weaving. When weaving, thick yarn is used to expand the gap between the coils, and then the high needle count of 36G is used to make the fabric more delicate; the high needle count of 36G makes the fabric more delicate, and will not make the vertical density too large when making 160 grams of weight, so as to maintain a certain lightness and breathability. The nylon yarn 7 and the spandex yarn 8 are wound into a braiding line 9, and then the warp thread 901 in the braiding line 9 and the weft thread 902 in the braiding line 9 are woven into the fabric. The high needle count of 36G means that the number of needles arranged on the circular machine is 36G, which means that there are 36 needles per inch.

After dyeing is completed, the dyeing water is pumped back to the warm water pool 302 through the first water pump 601, and the residue is discharged through the valve 1 to perform the color matching of the fabric. After the color matching is completed, the dyeing water is discharged into the dyeing pool 4 again for color fixing, and the color fixing agent is added to complete the color fixing work, and then the sewage is directly discharged into the treatment pool 2, and then the dyeing water is discharged into the treatment pool 2. The superheated water pool 303 injects water into the dyeing water pool 4 through the first water pump 601 and the hot water pipe 604 to neutralize the fabric, and the neutralized water is directly discharged into the treatment pool 2, and then water is injected into the dyeing water pool 4 through the warm water pool 302, the first water pump 601 and the warm water pipe 603 to neutralize it again, and the neutralized water is directly discharged into the treatment pool 2, and finally water is injected into the dyeing water pool 4 through the cold water pool 301, the first water pump 601 and the cold water pipe 602 for cleaning, and the cleaned water is pumped back into the cold water pool 301, and then the cloth discharge work is completed, and the water in the treatment pool 2 can be reused through the circulation group 5 after treatment, and the water is introduced into the corresponding preparation box 3 from the three-way pipe 502 through the circulation pipe 501, and the water pipe group 6 divides the equipment into three groups of facilities with different temperatures for easy use, and the control valve 503 can choose to pump water in.

[0023] Working principle: select 65D / 48F nylon filament FDY yarn plus 20D spandex yarn 8, then match the length of 65D / 48F nylon filament FDY yarn, adjust the length of the yarn to select the optimal ratio to reach 155 grams per square meter to resist UV rays, add sunscreen additives and super washable finishing additives, and finally weave.
