Problems solved by technology

[0003] Regarding the flame retardant treatment of wool, the earliest method is to immerse in phosphate and borate solutions and then dry. The resulting flame retardant wool fabric is not washable; The harm to the environment and human body has been eliminated; the "Zirpro" process promoted by the International Wool Bureau is a relatively successful wool flame-retardant method that has been used for a long time in the industry. This method uses potassium hexafluorotitanate and potassium hexafluorozirconate It is a flame retardant, and it is treated under acidic conditions without affecting the hand feel of the fabric. However, due to the fact that heavy metals have varying degrees of damage to the environment and the human body, and the physiological functions of titanium and zirconium on the human body are not yet clear, there are certain limitations in using this method. risk

Embodiment 1

[0023] Embodiment 1: A kind of flame retardant working liquid for preparing flame retardant wool fabric, by weight, the proportion is as follows:

[0024]

[0025] The rest is water.

[0026] The wool fabric to be treated is a pre-treated white cloth with a gram weight of 234g / cm 2 . The processing flow is as follows:

[0027] Preparation of working liquid → immerse the wool fabric in the working liquid for 1 minute, double dipping and rolling (95% rolling rate) → 102°C saturated steam steaming for 10 minutes → washing → drying.

Embodiment 2

[0029] The proportion of flame retardant working fluid by weight is as follows:

[0030]

[0031] The rest is water.

[0032] The wool fabric used is mercerized wool white cloth with a weight of 150g / cm 2 .

[0033] The processing flow is as follows:

[0034] Prepare the working solution → soak the wool fabric in the working solution for 1 minute, then soak twice and roll twice (95% rolling rate) → steam with saturated steam at 101°C for 8 minutes → wash with water → dry.

[0035] The flame retardant performance of treated wool is shown in Table 1:

Abstract

The invention discloses a method for preparing inflaming-retarding wool fabric and an inflaming-retarding working solution. The working solution contains the following components by weight: 15-30% of phosphorus-nitrogen components, 0.1-0.5% of ammonia water, 0.1-0.3% of initiator and the balance water, wherein the phosphorus-nitrogen components are formed by phosphorus-containing components and nitrogen-containing components, and the weight ratio of the phosphorus-containing components to the nitrogen-containing components is 1:(0.5-1). The wool fabric to be processed is processed in the inflaming-retarding working solution in a twice-soaking twice-rolling method, the dipping time is 1-3 minutes, mangle expression is more than 90%, and the inflaming-retarding wool fabric can be obtained through steaming, washing and drying. The method can remarkably reduce using amount of the phosphorus-containing components, can improve inflaming-retarding efficiency and is favorable for industrial production.

Description

technical field [0001] The invention relates to a post-finishing processing technology for natural fiber fabrics, in particular to a flame-retardant finishing method for wool, which belongs to the field of textile printing and dyeing functional finishing. Background technique [0002] Wool is a natural protein fiber, which is heat-preserving, sound-absorbing, acid-resistant, and not easy to ignite. It is widely used in suits, sweaters, high-temperature protective clothing, bedding, carpets, felt, and high-speed rail, aircraft interior decoration materials and other fields. Wool itself has a high nitrogen content (14-16%) and a certain sulfur content (3-4%) and is very easy to absorb moisture, so that it has a certain flame-retardant effect. Compared with other conventional fibers, it is not easy Burning fiber, the limiting oxygen index is 24-26%. However, this value still cannot meet the requirements of flame-retardant products. For example, in my country's "Flame-Retardant...
