Problems solved by technology

[0005] First, the fabrics obtained by the existing finishing process have unsatisfactory moisturizing performance, unsatisfactory moisture absorption and moisture release performance, and cannot achieve moisturizing and skin care effects, resulting in discrepancies between the propaganda and the reality
[0006] Second, the fabrics obtained by the existing finishing process have unsatisfactory washability
If hyaluronic acid silk fabrics want to play the role of moisturizing and skin care, they must be in contact with the skin. In order to maintain hygiene, the fabrics in contact with the skin need to be washed regularly; the hyaluronic acid silk fabrics obtained by the existing finishing process are not ideal in washability. Fabrics with hyaluronic acid content, but after customers buy and wash, the hyaluronic acid in the fabrics will be lost sharply, and the skin care effect will be lost
At present, the existing hyaluronic acid fabrics are washed 15 times at most, and the fabrics still contain hyaluronic acid. However, after the existing hyaluronic acid fabrics are washed 5 times, the remaining hyaluronic acid content in the fabrics is less than 20%. Contains hyaluronic acid, but the content is extremely low, and the fabric no longer has the effect of moisturizing skin care
[0007] Third, in the existing hyaluronic acid finishing process, in addition to adding hyaluronic acid finishing agents, preservatives and defoamers need to be added. These additives are easy to cause allergies in direct contact with the skin, and silk fibers are animal proteins. When these additives are attached On silk, the luster and shade of the fabric will change, which cannot meet customer requirements

[0052] The fabric of this embodiment is: plain silk crepe satin, grammage 91.6g / square meter, iron gray.

[0053] Finishing process, including the following steps:

[0054] 1) Dry the silk fabric at 112~114°C, roll it, and then pad the working fluid, with a surplus rate of 75%. The temperature is 20~23℃;

[0055] The pH of the working solution is 4.3. The working solution includes acetic acid, washable finishing agent, hyaluronic acid finishing agent and water. Washing agent and hyaluronic acid finishing agent are added at a mass ratio of 1:2.4;

[0056] 2) After padding, the silk fabric is dried at 128-130°C; then the silk fabric is stretched and shaped at 130°C-135°C at a speed of 30-35m / min.

Embodiment 3

[0058] The fabric of this embodiment is pure silk crepe satin, the grammage is 95.6g / square meter, beige.

[0059] Finishing process, including the following steps:

[0060] 1) Dry the silk fabric at 110~112°C, roll it, and then pad the working fluid, the excess rate is 77%. The temperature is 27~30℃;

[0061] The pH of the working solution is 4.1. The working solution includes acetic acid, washable finishing agent, hyaluronic acid finishing agent and water. The bath ratio of the washing-resistant finishing agent is 22g / L, and the bath ratio of the hyaluronic acid finishing agent is 57.2g / L; Washing agent and hyaluronic acid finishing agent are added at a mass ratio of 1:2.6;

[0062] 2) After padding, the silk fabric is dried at 126-128°C; then the silk fabric is stretched and shaped at 130°C-135°C at a speed of 30-35m / min.

Abstract

The invention discloses a post-finishing process of a hyaluronic acid real silk fabric, and belongs to the technical field of real silk post-finishing. The method comprises the following steps of 1) carrying out drying and rolling on a real silk fabric and then padding into a working liquid, wherein the working liquid comprises a washing-resistant finishing agent, a hyaluronic acid finishing agentand water, wherein the bath ratio of the washing-resistant finishing agent is 18-25 g / L, the bath ratio of the hyaluronic acid finishing agent is 36-75 g / L, and the washing-resistant finishing agentand the hyaluronic acid finishing agent are added at the mass ratio of 1 to 2-3; and 2) enabling the silk fabric after being subjected to padding to be dried at the temperature of 120-130 DEG C, and performing tentering and shaping to obtain the real silk fabric. By virtue of the post-finishing process of the hyaluronic acid real silk fabric, the obtained real silk fabric is excellent in washability, moisture absorption performance and moisture release performance, and the specific color light and hand feeling of real silk are kept.

Description

technical field [0001] The invention discloses a post-finishing process for hyaluronic acid silk fabrics, which belongs to the technical field of post-finishing silk. Background technique [0002] Silk fabrics refer to fabrics woven from silk fiber yarns, or fabrics interwoven with silk fiber yarns and other fiber yarns. Silk fiber is mainly composed of animal protein, rich in 18 kinds of amino acids necessary for the human body, has good air permeability, excellent hygroscopicity, has the reputation of "fiber queen", is called the second skin of the human body, and is widely used in clothing and silk scarves , Bedding field. [0003] Hyaluronic acid is one of the most hydrophilic molecules in nature. It has many benefits to the human body. It can improve skin nutrition metabolism, make skin soft, smooth, wrinkle-free, increase elasticity, prevent aging, and it is a good transdermal agent while moisturizing Absorption enhancers, known as "natural humectants". Due to the g...
