Definitions
- the invention relates to a post-treatment method for light and thin natural fiber materials, in particular to a flame retardant and clean treatment method. Background technique
- the ecological properties of fiber materials have been the focus of the world, and Europe, the United States and China have developed strict ecological standards.
- the fiber material with the ecological performance meets the requirements can ensure the health of the user and promote the harmonious development of the society.
- the production of flame-retardant cotton fabrics in foreign countries is mainly based on the technology of Pykovetex CP New and Proban, and most of them are medium-thick fabrics.
- the inventions of light-weight natural fiber flame retardant materials are rarely reported, and the specific performance is unknown.
- the flame retardant processing technology of flame retardant viscose fiber is relatively mature abroad.
- countries such as Europe, the United States, and Japan are keen on the invention and development of special high temperature resistant flame retardant fibers and materials.
- the invention and production of flame retardant natural fiber materials have a tendency to shift to foreign countries. In short, the flame retardant lightweight natural fiber materials are less invented at home and abroad and are more difficult.
- a heat-resistant flame-retardant fabric and a preparation method thereof the heat-resistant flame-retardant fabric is blended from two flame-retardant fibers,
- the flame retardant fiber is aramid 1313 fiber, and the other flame retardant fiber is flame retardant viscose fiber.
- the flame retardant content of various fibers in the flame retardant fabric is: aramid fiber: 20% ⁇ 80%, flame retardant adhesive Fiber: 20% ⁇ 80%.
- CN01813559 5 Fireproof yarn and fabric made thereof, comprising: a) 5-90wt.% melamine fiber, b) 5-90wt.% natural fiber, c) 0. l-30wt.% by polyamide 66, polyamide 6 or a polyamide fiber made from a mixture thereof.

- the effect of the amount of flame retardant on the flame retardancy and softness of fiber materials Due to the thinness, bulkiness, softness and large specific surface area of the ultrafine fiber material, the fiber material per unit mass contains a large amount of air, and the oxygen supply during combustion is sufficient, so that the ultrafine fiber material is relatively easy to ignite.
- the eco-efficient flame retardant is selected and the amount of the flame retardant is appropriately increased.
- the durable flame retardants which can be used for natural and mixed materials at home and abroad mainly include condensates of N-hydroxymethyl-3-dimethylphospholpropamide (Pyrovatex CP) and tetramethylolphosphonium chloride-urea.
- Proban type because Proban flame retardant is ammonia-cured when processing natural fiber materials, the degree of crosslinking is difficult to control, and the finishing products are harder, and the ultra-fine fiber materials cannot be used in flame-retardant processing.
- Pyrovatex CP flame retardants have a large number of domestic and foreign manufacturers and brands, and there is a certain gap in quality. Table 1 shows the performance comparison of six flame retardants.
- the fabric is 119. Ig/m2 cotton twill.
- the amount of flame retardant used directly affects the flame retardancy, feel and production cost of the fiber material.
- natural materials such as flame retardant JSJ-111, infiltrated with a high temperature baking cross-linking process, processing two natural fiber materials according to orthogonal test
- Figure 1 gives the effect of the concentration of the flame retardant on the weight gain of the fabric
- Figure 2 shows the relationship between the weight gain of the fabric and the length of the damage
- Table 2 shows the effect of the flame retardant on the fabric properties. It can be seen from Figure 1 that as the concentration of the flame retardant is used, the fabric gains weight.
- the cross-linking resin is JSJ 302, and the dosage is the same.
- the concentration of the agent also has a certain influence on the strength and color change of the fabric. Based on the above analysis, the concentration of the flame retardant used is 25% - 38% is an optimum value.
- the commonly used cross-linking resin is mostly a modified thiol melamine derivative with a reactive group, but its performance is also different due to the difference in chemical structure, molecular weight and reactive group content. Large differences, Table 3 lists the performance comparison of the five crosslinked resins. Table 3 Comparison of properties of five crosslinked resins
- the fabric is 119. lg/m 2 of cotton twill; the flame retardant is domestic JSJ-111.
- the cross-linked resin can not only form a strong chemical bond with the active groups of the flame retardant and the fiber material, but also adhere to the surface of the fine structure of the fiber material by permeation, relying on the intermolecular secondary bond force. Strongly combined.
- the amount of cross-linking resin directly affects the washing fastness, weight gain, and feel of the finished fabric.
- Figure 3 shows the effect of the amount of cross-linking resin on the washability and weight gain of the fabric.
- Table 4 lists the relationship between the cross-linking resin and the fabric feel, strength, color change and other indicators.
- the fabric is cotton twill (119. lg/m 2 ); the flame retardant is JSJ-111, the same amount of use; the cross-linked resin is JSJ-302. Coordination of indicators, the use concentration of cross-linked resin is 5.0% - 10% is most suitable.
- the ultra-microfiber material is infiltrated with a flame retardant, a cross-linking resin, a penetrating agent, etc. at a low temperature (15-30 ° C), and is parked at a lower temperature (20-80 ° C) for a certain period of time, at which time the fiber material is puffed.
- the loose and low-molecular additives are easily penetrated into the fine structure of the fiber material, and when dried and cross-linked, the surface resin is not formed, thereby greatly improving the hand feeling and strength of the flame-retardant fiber material.
- Table 5 shows the effect of the expansion temperature and time on the properties of the fabric.
- the fiber material is: cotton twill (40 s X40 s 119. lg/m 2 ).
- High temperature baking cross-linking is a key process in the flame retardant processing of fiber materials, which largely determines the hand of the finished product. Sense, washability, loss of strength and color change.
- High temperature baking cross-linking is a very complicated physical and chemical process; it has cross-linking between flame retardant and fiber material, cross-linking between fiber material, flame retardant and cross-linking resin, as well as flame retardant and cross-linking.
- the co-resin penetrates and adheres to the inside of the fiber material, and forms a very strong physical adsorption by the intermolecular bond force.
- the key parameters of high temperature baking cross-linking are baking temperature and baking time: high temperature and long time.
- the chemical reaction is thorough, the degree of crosslinking is high, and the fabric has good washing durability, it will make the hand feel hard and the strength loss is large.
- the side reaction is increased, and the formed compound reacts with free formaldehyde to form a fatty amine substance with fishy smell; if the baking temperature is too low and the time is too short, the crosslinking is insufficient, thereby affecting the washing resistance of the fiber material. Fastness and flame retardancy, a large number of tests have proved: the baking temperature is 145-185 °C, and the baking time is -8 minutes, which is a reasonable high-temperature baking crosslinking condition.
- Ultrafine fiber materials produce trace amounts of free formaldehyde and fatty amines with fishy odor during flame retardant processing, and fatty amines with fishy odors, during storage and transportation of products, such as encountering suitable temperatures and Humidity will also be produced in small amounts.
- heavy metal content, limited flame retardant and ra value are easier to solve, while odor and free formaldehyde have become key indicators, and these two indicators are largely interrelated.
- Ultra-fine flame-retardant fiber materials can generate free electrons and holes under the irradiation of sunlight or light after introducing nano-scale zinc oxide (ZnO) or titanium dioxide (Ti0 2 ), and oxygen and water molecules in the air.
- the reaction produces a highly oxidizing ability of hydroxyl radicals and active oxygen, and thus has a strong photo-oxidation-reduction function.
- Harmful organic matter formaldehyde, fatty amines, etc.
- odors, bacteria, etc. which are adsorbed by active oxygen, are immediately reduced to harmless carbon dioxide, water and oxygen.
- the flame retardant fiber material is not visible or the light is weak during packaging or transportation, which will affect the photocatalytic effect of the nano material.
- the odor or formaldehyde on the ultrafine flame retardant material is adsorbed by a material having micropores, voids or a large specific surface area, and stored in its internal structure.
- the problem with this method is that the adsorption has a saturation process, and at the same time, during the water washing, desorption occurs and some of the gas is released again.
- a substance that can react chemically with fatty amines and formaldehyde is applied to the ultra-fine flame-retardant fiber material, which can easily remove odor and formaldehyde, but the adhesion and use of the material to the fiber material is incomprehensible.
- the ultra-viral flame retardant fiber materials were treated with three ecological cleanliness theories and five cleansers were selected. The results are shown in Table 6.
- the fiber material is: flame retardant cotton flat cloth ( 40 s X 40 s 128. 4g/m 2 );

- the results are shown in Table 7.
- Nano-composite clean liquid does not stratify, not demulsification, and no precipitation during use.
- Ultra-microfiber material (light-weight cotton fabric) Bleaching or dyeing - low temperature infiltration (flame retardant) - one baking cross-linking - oxidation, neutralization, water washing - nano-ecological clean - finished product inspection
- Crosslinked resin JSJ-302 Auxiliary crosslinked resin JSJ-303 0.5-2.0
- Cleaner JSJ-605 (Adsorbed material) 0.9—12.0 Cleaner JSJ-601 (Reactive material) 0.5— 5.2
