Problems solved by technology

The pure cotton flame-retardant fabric finished by Proban has excellent flame-retardant effect, soft hand feeling, low toxicity and environmental protection, safe and reliable to the human body, small loss of strength, strong durability, and basically maintains the comfort and durability of the original fabric, etc., and The flame retardant performance of the product can meet the standards of many countries in the world, and is suitable for making all kinds of protective clothing, bedding, decorative items and children's flame retardant pajamas, etc., but the process is complicated to operate and the cost is high, and Proban finishing is mainly used for shuttle fabric
For knitted fabrics, since it is composed of coils, each coil can be divided into three parts. The coils in knitted fabrics are not planar structures, but curved curves in three-dimensional space, which can deform regardless of the force in any direction. When the knitted fabric is subjected to a large longitudinal stretch, the longitudinal elongation of the knitted fabric and the transverse shortening, only when the fabric is compressed longitudinally, it is possible to return to its original shape, so it is easy to deform and difficult to arrange, so it is not suitable for Proban finishing method

preparation example Construction

[0027] The specific process of the preparation method of the moisture-absorbing and quick-drying flame-retardant fabric of the present invention is as follows:

[0028] A. Prepare flame retardant finishing solution, which includes flame retardant finishing agent. After a large amount of local focus of flame retardant finishing agent on knitted fabric, it will cause the hand feeling of knitted fabric to become hard, so softener can be added to properly disperse flame retardant ; At the same time, in order to obtain a good flame retardant effect, the flame retardant needs to penetrate into the amorphous region and gap of the fabric, so a penetrating agent can be added to facilitate the penetration of the flame retardant finishing agent into the fabric. However, if the concentration of the flame retardant finishing agent is too high, it will affect the feel and color of the knitted fabric and the cost of the flame retardant is high, and if the concentration of the softener is too...

Embodiment 1

[0045] Add a certain amount of water into the mixing tank, then add tetrakis hydroxymethyl phosphorus chloride urea condensate, softener and penetrating agent in turn, stir evenly, and prepare a flame retardant finishing solution, in which tetrakis hydroxymethyl phosphorus chloride urea condensation The concentration of the softener is 300g / L, the concentration of the softener is 20g / L, and the concentration of the penetrating agent is 2g / L. The cotton knitted fabric is subjected to two-dipping and two-rolling processing in the flame-retardant finishing solution, and the rolling rate of the fabric is 90%; the cotton knitted fabric is dried at a temperature of 70°C, and the drying time is 3 minutes; the drying is completed Then enter the airtight environment with an ammonia gas flow rate of 50m³ / h for ammonia fumigation. At the same time, add 8g / L hydrogen peroxide to the liquid flow machine and run it for 5 minutes, and directly add the cotton knitted fabric after ammonia fumig...

Abstract

The invention relates to a preparation method of a moisture-absorbing quick-drying flame-retardant knitted fabric. The method comprises the following steps of a) preparing a flame-retardant finishingliquid; b) padding the knitted fabric in the flame-retardant finishing liquid; c) drying the padded knitted fabric; d) performing ammonia fumigation on the dried knitted fabric; e) oxidizing the knitted fabric subjected to ammonia fumigation in a liquid flow machine; f) washing the oxidized knitted fabric with water in the liquid flow machine; g) carrying out padding and finishing on the washed knitted fabric by using a moisture-absorbing and quick-drying finishing agent; and h) overfeeding and drying the knitted fabric in a stenter. According to the method, flame-retardant finishing of the knitted fabric is achieved, the defects that the knitted fabric is prone to denaturation and difficult to finish are overcome, the flame-retardant performance of the finished knitted fabric reaches theB1-level standard, and the flame-retardant performance of the finished knitted fabric is still B1-level after the knitted fabric is washed many times; Meanwhile, the knitted fabric is subjected to moisture absorption and quick-drying finishing, the finished knitted fabric reaches the performance index of moisture absorption and quick drying, and the requirements of people for the multifunctional knitted fabric are met.

Description

technical field [0001] The invention relates to the technical field of functional textiles, in particular to a method for preparing moisture-absorbing and quick-drying flame-retardant knitted fabrics. Background technique [0002] Since the beginning of the 21st century, my country's knitwear industry has entered the fastest growing period in history, with an annual processing volume of over 10 million, ranking first in the world. Knitted fabrics have good hand feeling, drapability, and soft texture. In addition to good wrinkle resistance and breathable moisture permeability, they also have greater extensibility and elasticity. Therefore, knitted fabrics are widely used in underwear, tights and sportswear, etc. It has also been widely used in fields such as industry, agriculture and medical care. However, the performance of knitted products on the market is single. By endowing knitted fabrics with more special functions, such as flame retardancy, moisture absorption and qui...
