Problems solved by technology

The wool fabric obtained through the above process has certain antibacterial ability and anti-insect property, but because it is difficult for pectin to penetrate between the surface scales of wool fiber, the antibacterial ability of pectin lasts for a short time
Relatively speaking, the scales of cashmere cover the hair shaft tightly, which is relatively smooth and flat, so it is more difficult for pectin to penetrate deeply.

Embodiment 1

[0017] Example 1 The pectin antibacterial finishing process of cashmere fabric includes the following steps:

[0018] S1: Crush the pectinaceous sandalwood bark, place the pectinaceous sandalwood bark crushed material in an organic acid solution, and sequentially heat and reflux the pectin extraction, the extraction solution filtration, the extraction solution concentration, ethanol precipitation and washing, pectin precipitation, drying pectin Step, obtaining pectin for finishing the pectinate peel;

[0019] S2: Put the pectin for finishing in water, heat and stir until the pectin is dissolved in the water, to obtain the pectin finishing liquid for peonies sandalwood peel;

[0020] S3: Put the cashmere fabric in a pectin finishing solution at 75°C for padding treatment, then place it in a steaming box to steam for 10 minutes, take out the cashmere fabric and bring it to room temperature, wash and dry with water.

[0021] The organic acid is acetic acid, and the pH of the organic acid...

Embodiment 2

[0026] The difference between Example 2 and Example 1 is: S3: Put the cashmere fabric in a pectin finishing solution at 85°C for padding treatment, then place it in a steaming box to steam for 5 minutes, take out the cashmere fabric and bring it to room temperature , Rinse with water and dry.

[0027] The organic acid is malic acid, and the pH of the organic acid solution is 2.

[0028] The heating and refluxing pectin extraction time is 100min, and the bath ratio of the pulverized sandalwood bark material and the organic acid solution is 1:40.

[0029] The heating temperature of water in S2 is 70°C, and the weight percentage of pectin in the pectin finishing solution is 7%.

[0030] The drying temperature of pectin in S1 is 60°C. The steaming temperature in S3 is 120°C.

Embodiment 3

[0032] The difference between Example 3 and Example 1 is: S3: Put the cashmere fabric in a pectin finishing solution at 80°C for padding, then place it in a steaming box to steam for 7 minutes, take out the cashmere fabric and bring it to room temperature , Rinse with water and dry.

[0033] The organic acid is a 1:1 combination of citric acid and tartaric acid, and the pH value of the organic acid solution is 1.5-2.

[0034] The heating and refluxing pectin extraction time is 200 minutes, and the bath ratio of the pulverized sandalwood bark material and the organic acid solution is 1:35.

[0035] The heating temperature of water in S2 is 72°C, and the weight percentage of pectin in the pectin finishing solution is 5%.

[0036] The drying temperature of pectin in S1 is 65°C. The steaming temperature in S3 is 110°C.

Abstract

The invention discloses an antibacterial finishing process of pectin for a cashmere fabric. The process comprises the following three steps: extracting pectin; dissolving the pectin; and finishing thepectin. By adding a steaming step in the antibacterial finishing process of pectin for the cashmere fabric, steaming has a certain destroying effect to scales of cashmere, the attaching amount of thepectin among the scales of cashmere is added, and the antibacterial property is more lasting.

Description

Technical field [0001] The invention relates to the technical field of cashmere processing, in particular to a pectin antibacterial finishing process for cashmere fabrics. Background technique [0002] Natural pectins are widely present in the fruits, roots, stems, and leaves of plants in the form of protopectin, pectin, and pectic acid. They are a component of cell wall. They exist along with cellulose and constitute adjacent The adhesive in the middle layer of cells makes the plant tissue cells tightly bonded together. Protopectin is a substance insoluble in water, but it can be converted into water-soluble pectin by hydrolysis under the action of acid, alkali, salt and other chemical reagents and enzymes. Pectin has excellent antibacterial and anti-ultraviolet effects. Public documents such as CN104532570A disclose a functional finishing method of mallow stem bark pectin on wool fabrics. The specific finishing process is to completely dissolve the pectin, and immerse the pre...
