Embodiment 1

[0048] Preparation of slurry for coating and finishing of nano-sized pearl particles:

[0049] The formula of the coating slurry is as follows:

[0050] Pearl powder 200 g / L,

[0051] Emulsifier AC 10 g / L,

[0052] Dispersant N 60 g / L,

[0053] Water reducer T 80 g / L,

[0054] water deionized water;

[0055] Among them, the emulsifier AC is a product of Jiangsu Sixin Interface Agent Technology Co., Ltd.; the dispersant N is a product of Shanghai Kangdun Fine Chemical Co., Ltd.; the water reducing agent T is a product provided by Shanghai Wuze Industry and Trade Co., Ltd. stability, and improve the water resistance of the pearl particle layer on the surface of the fabric and yarn after finishing.

[0056] Since pearl powder has a specific gravity of 1.75-1.86, it sinks when it enters water, and the surface of the particles is negatively charged when dispersed in water. Generally, anionic dispersants are not easy to access and emulsify pearl particles. For this rea...

Embodiment 2

[0059] Padding finishing of fabrics (1).

[0060]The fabric used is Leo bamboo / bamboo pulp fiber 15 / 85 blended fabric, with a warp density of 667 threads / 10cm, a weft density of 358 threads / 10cm, and a yarn density of 18.2 tex. Among them, "Leo Bamboo" is developed by Shanghai Leo Fiber Fiber supplied by Ltd.

[0061] A. The formula of the padding finishing liquid of described fabric is:

[0062] 70 g / L slurry for coating and finishing nano-sized pearl particles,

[0063] Adhesive PS 20 g / L,

[0064] water deionized water;

[0065] Among them, the adhesive PS is a product of Shanghai Kangdun Fine Chemical Co., Ltd.

[0066] B. The padding finishing of the fabric is carried out on a continuous dyeing pad car, and the technological process and parameters are:

[0067] Fabric → padding finishing liquid (two dipping and two padding, liquid rolling rate 85%) → pre-drying (80°C, 3 min) → baking (130°C, 1 min) → padding softener W (the amount of softener W is 20...

Embodiment 3

[0070] Padding finishing of fabrics (2).

[0071] The fabric used is bamboo pulp fiber / PTT / medium denier high elastic acrylic fiber 68 / 30 / 2 blended fabric, the yarn is 27.8 tex double-ply yarn, the warp density of the fabric is 425 threads / 10cm, and the weft density is 228 threads / 10cm.

[0072] The padding finishing solution and the padding finishing process are the same as in Example 1.

[0073] After finishing, it is tested that the UV transmittance of the fabric is 0.1% for UVA and 0.1% for UVB; the UV protection factor UPF is more than 50; and it has high far-infrared emission performance (0.9).

Abstract

The invention relates to a coating and finishing method for nanoscale pearl particles applied to a textile and a yarn in spinning dyeing production. The method comprises the following steps: preparing a sizing agent used for coating and finishing; padding the textile; and soaking the yarn. A formula of the sizing agent used for coating and finishing comprises pearl powder, an emulsifying agent, adispersing agent, a water-reducing agent and water, wherein the components are uniformly mixed and then are ground on a grinding machine, thereby obtaining the sizing agent used for coating and finishing the nanoscale pearl particles. On a continuous dyeing padder and an overflow dyeing agent, a finishing solution prepared by using the sizing agent is respectively used for padding the textile andsoaking the yarn. Compared with the textile made of pearl viscose, the obtained textile after being finished has the advantages that the textile is suitable for various natural fiber and chemical fiber textiles; a conventional dyeing device is used for finishing and the method is simple; the content of the pearl particles on the textile is high and the processing cost is low; and the textile after being finished has an ultraviolet ray resisting function and a far-infrared emission function.

Description

technical field [0001] The invention relates to the post-finishing technology of textile printing and dyeing production, and specifically refers to a method for coating and finishing textiles, including woven fabrics, knitted fabrics and yarns, with nano-scale pearl particles. Background technique [0002] Pearls are widely used in fields such as medicine, decorations and beauty cosmetics. The main component of pearls is calcium carbonate, which also contains more than 10 kinds of amino acids and various trace elements necessary for the human body, which can play the role of skin care and health care. [0003] At present, the pearl viscose fiber produced by blending ultrafine pearl particles and viscose has come out, but the fiber spinning process is complicated, the production cost is high, the actual pearl content is low, and the fiber type is single. When pearl ultrafine powder is added in the production process of the above-mentioned pearl viscose fiber, the powder is e...
