Problems solved by technology

[0005]The second is to peel off the scale layer of the wool fiber to reduce the friction effect of the fiber. The antistatic performance obtained by this method is permanent, but it will damage the wool fiber and the strength of the fabric;
The wool fabric referred to by this method has poor antistatic durability

Embodiment 1

[0027] The antistatic finishing process of embodiment 1 worsted wool fabric comprises the following steps:

[0028] S1: Configure the pretreatment solution, add the reducing agent mercaptoethanol and lipoic acid into the water, adjust the pH value of the pretreatment solution to 8.5 with sodium hydroxide solution,

[0029] S2: Immerse the worsted wool fabric in the pretreatment solution, based on the weight of the worsted wool fabric, the amount of reducing agent is 8% o.w.f., the amount of lipoic acid is 1% o.w.f., and the bath ratio is 1:15. The temperature of the pretreatment solution is raised to 60-65°C, and the temperature is kept for 2 hours, then the temperature is lowered, and the worsted wool fabric is taken out, washed and dried;

[0030] S3: Padding and finishing the worsted wool fabric obtained in S1 with Span 80 dispersion: the pH value of the antistatic finishing agent dispersion was adjusted to 5 with hydrochloric acid, based on the weight of the worsted wool f...

Embodiment 2

[0032] Embodiment 2 is based on Embodiment 1, the difference is that the disk 60 is used instead of the disk 80 .

Embodiment 3

[0034] Embodiment 3 is based on Embodiment 1, the difference is that the antistatic finishing agent is antistatic agent SN.

Abstract

The invention discloses an antistatic finishing process for a worsted wool fabric. The antistatic finishing process comprises the following steps that S1, the worsted wool fabric is impregnated in a pretreatment liquid mainly composed of a reducing agent, lipoic acid, a pH regulator and water, heated, subjected to heat preservation reaction, washed with water, and dried; and S2, the worsted wool fabric obtained in the step S1 is padded and finished by adopting an antistatic finishing agent solution or dispersion liquid, and an antistatic worsted wool fabric is obtained through pre-baking to drying and baking, wherein the pH value of the pretreatment liquid is 8-9, the heating reaction temperature is 55-70 DEG C, an antistatic finishing agent in the antistatic finishing agent solution or dispersion liquid is a polyhydric alcohol antistatic finishing agent, and the pH value of the antistatic finishing agent solution or dispersion liquid is 5-6. According to the antistatic finishing process for the worsted wool fabric, the fabric is pretreated by adopting the reducing agent and the lipoic acid, then the fabric is finished by using the antistatic finishing agent, and the pretreated worsted wool fabric is more resistant to static electricity, more washable and more excellent in durability.

Description

technical field [0001] The invention relates to the technical field of worsted wool fabric production, in particular to an antistatic finishing process for worsted wool fabric and the worsted wool fabric. Background technique [0002] Wool fabric has good warmth retention, wrinkle resistance and abrasion resistance, and is usually used in cold environments. However, under dry and low temperature conditions, the friction between fibers of wool products is prone to electrification, and the charges accumulate on the surface of wool fibers for a long time, which leads to static electricity during wearing. A further problem caused by static electricity is the adsorption of dust and the generation of electric shock. [0003] The main means to improve the electrostatic phenomenon of wool fabrics include the following three: [0004] One is to use fiber with good electrical conductivity and wool blend; [0005] The second is to peel off the scale layer of wool fiber to reduce the...
