Problems solved by technology

Although it adopts the method of hydrothermal modification of butyl titanate to anti-ultraviolet finishing of cotton fabrics, it does solve the problem that nanoparticles are easy to agglomerate and the bonding fastness between particles and fabrics is poor, but its disadvantage is that Since the cotton fibers are extruded and twisted during the yarn forming and weaving process, the butyl titanate sol solution is affected to penetrate into the cotton fibers, so that most of the titanium dioxide produced in this method is generated in the interweaving gaps of the cotton fabric yarns, and some It exists in the gaps of the fibers in the yarn, which makes the titanium dioxide finishing agent easy to fall off from the fiber surface during washing or wearing of cotton fabrics (it will pollute other clothes during washing, and the dusty titanium dioxide that falls off during wearing will cause inhalation to the human body. Sexual hazards), affecting the anti-ultraviolet effect of cotton fabrics
In addition, the titanium dioxide generated in these areas appears white, causing white spots on the yarn-dyed cotton fabric, which affects the appearance of the fabric, thereby limiting the range of product applications of this method

Embodiment 1

[0036] According to the above process steps: select 5g of long-staple cotton as the cotton fiber to be treated with UV resistance, weigh 0.25g of butyl titanate and mix with 250ml of absolute ethanol, stir evenly to prepare a sol solution with a concentration of 1g / L, and mix 5g of cotton The fibers were immersed in 150ml of the prepared sol solution, and stood at 20°C for 10min. The cotton fiber after soaking is rolled, and the rolling pressure is 0.2MP. The cotton fibers after padding were subjected to steam treatment under steam at 60°C for 5 min, and washed with clean water. The washed cotton fiber is dried until dry, and the drying temperature is 50°C.

[0037] The long-staple cotton yarn after the anti-ultraviolet treatment of this embodiment was spun and woven, and the ultraviolet protection factor (UPF) of the pure cotton fabric was tested to be 39.1.

Embodiment 2

[0039] According to the above process steps: select 5g of fine-staple cotton as the cotton fiber to be anti-ultraviolet finishing, weigh 0.75g of butyl titanate and mix with 250ml of absolute ethanol, stir evenly to prepare a sol solution with a concentration of 3g / L, and mix 5g of cotton The fibers were immersed in 200ml of the prepared sol solution, and stood at 30°C for 15min. The cotton fiber after soaking is rolled, and the rolling pressure is 0.4MP. The cotton fibers after padding were subjected to steam treatment under steam at 70°C for 7 min, and then washed with water. The cotton fiber after washing is dried to dryness, and the temperature of drying is 60 ℃.

[0040] After the anti-ultraviolet treatment of this embodiment, the fine-staple cotton was spun and woven, and the ultraviolet protection factor (UPF) of the pure cotton fabric was tested to be 43.7.

Embodiment 3

[0042] According to the above process steps: select 5g of long-staple cotton as the cotton fiber to be anti-ultraviolet finishing, weigh 1.5g of butyl titanate and mix with 300ml of absolute ethanol, stir evenly to prepare a sol solution with a concentration of 5g / L, and mix 5g of cotton The fibers were immersed in 250ml of the prepared sol solution, and stood at 40°C for 20min. The soaked cotton fibers are rolled and pressed at a rolling pressure of 0.6MP. The cotton fibers after padding were subjected to steam treatment under steam at 80°C for 10 min, and then washed with clean water. Dry the washed cotton fiber until dry, and the drying temperature is 70°C.

[0043] After the anti-ultraviolet treatment of this embodiment, the long-staple cotton was spun and woven, and the ultraviolet protection factor (UPF) of the pure cotton fabric was tested to be 46.6.

Abstract

The invention relates to an anti-ultraviolet method for cotton fibers, and belongs to the technical field of textile materials. The method comprises the following steps: carrying out pad-roll treatment on a sol solution prepared from butyl titanate for the cotton fibers and ethanol, and carrying out steam treatment to form titanium dioxide in the cotton fibers. The method can be suitable for cotton spinning yarn dyeing, and is simple in process and low cost; a fabric prepared from the fibers has the advantages that titanium dioxide powder does not drop during washing and wearing, the anti-ultraviolet performance is durable, and the hand feel is good.

Description

technical field [0001] The invention relates to an anti-ultraviolet method for cotton fibers, which belongs to the technical field of textile materials. Background technique [0002] With the development of science and technology and the improvement of living standards, people's requirements for additional functions of clothing are also getting higher and higher. Cotton fiber is the most used natural cellulose fiber, and the knitted or woven fabrics made of it have good moisture absorption, air permeability and wearing comfort, so they are very suitable for summer clothing. Intense outdoor ultraviolet radiation in summer can cause skin pigmentation, which can cause skin cancer in severe cases. Because cotton fiber itself has poor UV resistance, and summer fabrics are relatively light, this results in poor UV resistance of cotton fabrics, so it is necessary to It is finished with anti-ultraviolet function. [0003] At present, the anti-ultraviolet functional finishing of co...
