紡織品作為國計(jì)民生中不可缺少的組成部分，其按照用途分為服用紡織品、裴飾用紡織品和產(chǎn)業(yè)用紡織品三大類，它們在人們?nèi)粘Ｉ钪姓紦?jù)著重要的地位。但是，紡織品由于其組成原料的原因比較容易燃燒，近年來，由紡織品保管不當(dāng)或者在使用過程中著火引起的火災(zāi)多有報(bào)道，給消費(fèi)者的人身及財(cái)產(chǎn)安全帶來了較大的沖擊。所以，紡織品需要進(jìn)行不同程度的阻燃整理，使其不僅可以為消費(fèi)者提供物質(zhì)需要，還可以有效地提高安全性。隨著紡織科技的進(jìn)步和人們生活水平的不斷提高,紡織品的阻燃整理研究也得到了進(jìn)一步的發(fā)展，并取得了一定的研究成果。
   紡織品阻燃纖維生產(chǎn)方法  
   與普通纖維不同，阻燃纖維具有良好阻燃性，可以延緩火勢的蔓延。阻燃纖維可以分為兩類，一類是纖維本身具有一定的阻燃性能，如聚間苯二甲酰間苯二胺纖維、聚酰胺一酰亞胺纖維等，現(xiàn)已廣泛應(yīng)用于各種耐高溫和阻燃的工作環(huán)境；另一類是對常規(guī)纖維進(jìn)行改性而獲得。  
   由于常規(guī)纖維來源廣、數(shù)量多、價(jià)格廉，所以它們是一般阻燃產(chǎn)品最常用的原料。按照阻燃劑與纖維大分子結(jié)合方式的不同，常規(guī)纖維阻燃改性的方法可大致分為如下幾種：  
   共聚法：阻燃效果持久，但工藝復(fù)雜，成本較高。  
   共混法：也叫添加法，耐久性不如用共聚法生產(chǎn)的纖維。  
   皮芯復(fù)合紡絲法：纖維穩(wěn)定性好，強(qiáng)度和均勻度都較高，但設(shè)備復(fù)雜昂貴，成本太高。  
   紡織品阻燃整理方法  
   織物的阻燃整理指的是阻燃劑通過物理（吸附、沉積、粘合）或化學(xué)（化學(xué)鍵）結(jié)合方式覆在織物上的過程。經(jīng)過阻燃處理的紡織品不能被明火點(diǎn)燃，火焰蔓延速度降低，燃燒性能降低，移去火源后，紡織品不會燃燒，陰燃時(shí)間縮短不陰燃，并且燃燒過程釋放的總熱量降低，形成較厚的炭層。

Application of flame retardant in textile industry

As an indispensable part of the national economy and people's livelihood, textiles are divided into three categories according to their uses: clothing textiles, decorative textiles and industrial textiles. They occupy an important position in people's daily life. However, textiles are relatively easy to burn due to their constituent raw materials. In recent years, there have been many reports of fires caused by improper storage of textiles or fire during use, which has brought a greater impact on the personal and property safety of consumers. Therefore, textiles need different degrees of flame retardant finishing, so that it can not only provide consumers with material needs, but also effectively improve safety. With the advancement of textile technology and the continuous improvement of people's living standards, the research on flame retardant finishing of textiles has also been further developed, and certain research results have been achieved.

Production method of textile flame retardant fiber

Different from ordinary fibers, flame retardant fibers have good flame retardancy and can delay the spread of fire. Flame retardant fibers can be divided into two categories, one is that the fibers themselves have certain flame retardant properties, such as poly-m-phenylene isophthalamide fibers, polyamide-imide fibers, etc., which have been widely used in various High temperature resistant and flame retardant working environment; the other type is obtained by modifying conventional fibers. 

Due to the wide source, large quantity and low price of conventional fibers, they are the most commonly used raw materials for general flame retardant products. According to the different ways of combining flame retardants and fiber macromolecules, conventional methods of fiber flame retardant modification can be roughly divided into the following categories:

Copolymerization method: The flame retardant effect is lasting, but the process is complicated and the cost is high. 

Blending method: also called additive method, the durability is not as good as fibers produced by copolymerization method. 

Skin-core composite spinning method: The fiber has good stability, high strength and uniformity, but the equipment is complex and expensive, and the cost is too high. 

Textile flame retardant finishing method

The flame retardant finishing of fabrics refers to the process in which flame retardants are coated on fabrics by physical (adsorption, deposition, adhesion) or chemical (chemical bonds) bonding. The flame retardant treated textiles cannot be ignited by open flames, the flame spread speed is reduced, and the combustion performance is reduced. Thick carbon layer.
