Description

Technical Field

[0001] The invention relates to the technical field of fabrics, and in particular to an anti-pilling skin-friendly fabric and a preparation method thereof. Background Art

[0002] Cashmere is a precious natural protein fiber with a fineness as low as 14μm. It has excellent properties such as being fine, light, soft, smooth, warm and skin-friendly. Bamboo fiber has a soft touch, feels comfortable on the skin and has excellent skin-friendliness. Fabrics made with cashmere and bamboo fiber have excellent skin-friendly properties.

[0003] However, cashmere fibers have scales on their surface. When exposed to moisture, heat, chemicals, and external forces, the fiber aggregates are tightly entangled, and felting occurs under certain conditions. The looped fibers on the fabric surface are also prone to slipping out and forming fluff with the free-end fibers on the surface. Under the action of external forces, they gradually entangle into balls. The pilling problem of cashmere fabrics during wearing has always had a negative psychological impact on consumers and has also troubled the entire cashmere industry. In addition, because cashmere has a microporous structure, it becomes a breeding ground for microorganisms such as bacteria and fungi to grow and reproduce under the combined effects of the wearer's body temperature, moisture emitted by the human body, and metabolites of the skin. Therefore, the antibacterial properties of the fabric also need to be improved.

[0004] Chinese patent CN112609463B discloses a method for preparing an anti-pilling agent for blended fabrics. The anti-pilling agent is prepared by mixing a polymer emulsion of methacrylate and a polymer emulsion of silicone. The anti-pilling agent can improve the anti-pilling performance of the fabric and improve the softness of the fabric. However, the polymer emulsion of methacrylate and the polymer emulsion of silicone have completed the polymerization between monomers during the preparation process. The adhesion strength between the anti-pilling agent and the fabric is low, the anti-pilling performance needs to be improved, and the antibacterial property of the fabric has not been improved. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an anti-pilling skin-friendly fabric and a preparation method thereof, so as to solve the problem that the cashmere-containing fabric in the prior art has poor anti-pilling performance and antibacterial performance.

[0087] Test example

[0088] The fabrics prepared in the above embodiments and comparative examples were tested for performance:

[0089] (1) Anti-pilling performance: The anti-pilling performance of the fabrics prepared in Examples 1-6 and Comparative Examples 1-2 was measured with reference to the standard GB / T4802.2-2008 "Determination of the pilling properties of textile fabrics Part 2: Modified Martindale method", with a load mass of 155 g and a friction number of 2000 times. The anti-pilling performance of the fabrics was determined based on the level, with a level of 1 indicating severe pilling on the surface, a level of 2 indicating obvious pilling on the surface, a level of 3 indicating moderate pilling on the surface, a level of 4 indicating slight pilling on the surface, and a level of 5 indicating no change. The test results are shown in Table 1:

[0090] Table 1

[0091]

[0092] As shown in Table 1, the fabric prepared by the present invention has good anti-pilling performance. Through the milling treatment, the fineness and softness of the fabric can be improved, the texture of the fabric can be made compact, and the anti-pilling performance can be improved; under the action of the photoinitiator and under the irradiation of ultraviolet light, the monomers in the finishing agent emulsion can be polymerized and cross-linked to form a resin film layer, and the entanglement between the cross-linked resin molecular chains and the fabric fibers can improve the adhesion strength between the resin film layer and the fabric, further improving the anti-pilling effect of the fabric.

[0093] (2) Soft and skin-friendly performance: The drape coefficients of the fabrics prepared in Examples 1-6 and Comparative Examples 1-2 were measured with reference to the standard FZ / T01045-1996 "Determination of drape properties of textile fabrics". The test results are shown in Table 2:

[0094] Table 2

[0095]

[0096] As shown in Table 2, the fabric prepared by the present invention has good soft and skin-friendly performance. The drape of the fabric is an important indicator of the wearability of the fabric. Clothing with good drape can form a smooth and fluent curved surface shape, and can fit the human body properly, and is soft and skin-friendly. Adding silicone oil to the finishing agent emulsion can effectively improve the softness of the fabric and reduce the deterioration of the softness caused by the formation of the resin film layer. The silicone oil is vinyl silicone oil, which can participate in the polymerization cross-linking reaction and be connected to the resin film layer in a chemically bonded manner, and has stable functions. Compared with Example 2, in Comparative Example 2, due to the absence of the addition of vinyl silicone oil, the softness of the fabric decreases and the drape coefficient increases significantly.

[0097] (3) Antibacterial performance: The antibacterial rates of the fabrics prepared in Examples 1-6 and Comparative Examples 1-2, as well as the antibacterial rates of the fabrics after washing 30 times, were measured with reference to the standard GB / T 20944.3-2008 "Evaluation of antibacterial properties of textiles Part 3: Oscillation method". The test results are shown in Table 3:

[0098] Table 3

[0099]

[0100] As shown in Table 3, the fabric prepared by the present invention has good antibacterial properties. Adding nano zinc oxide and 5',5-diallyl-2,2'-biphenol to the finishing agent emulsion can effectively improve the antibacterial properties of the fabric. The alkenyl introduced by the nano zinc oxide through the reaction with 3-(methacryloyloxy)propyltrimethoxysilane and the alkenyl contained in 5',5-diallyl-2,2'-biphenol can participate in the polymerization cross-linking reaction and be connected to the resin film layer with a stable chemical bond. Through the entanglement between the cross-linked resin molecular chain and the fabric fiber, the nano zinc oxide and 5',5-diallyl-2,2'-biphenol have high adhesion strength with the fabric and stable antibacterial properties. Compared with Example 2, in Comparative Example 1, the nano zinc oxide is not modified with alkenyl, and cannot be connected to the resin film layer in a chemically bonded manner, and the adhesion strength with the fabric is reduced, and the antibacterial properties are reduced.

[0101] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
