Abstract
The invention discloses a preparation method of a flame-retardant photochromic silk fabric. The method comprises the following steps: (1) preparing a padding liquid: ultrasonically and uniformly stirring photochromic powder, a flame retardant, a softening agent, a crosslinking agent, catalyst and deionized water to obtain the padding solution; (2) soaking the silk fabric in the padding solution, padding twice and rolling twice, wherein the pick-up rate is 80-90%; (3) taking out the silk fabric, washing for 2-3 times by using hot water, washing for 2-3 times by using cold water, drying for 5-10 min at 50-80 DEG.C, baking for 2-5 min at 120-150 DEG.C to obtain the flame retardant photochromic silk fabric. The flame-retardant photochromic silk fabric prepared by the invention is soft and comfortable, the limiting oxygen index reaches up to 40% or above, the free formaldehyde is less, and the environment is protected.
Description
Technical field:
The present invention relates to silk technical field, relate to a kind of preparation method of fire-retardant sensitization discoloration silk fabric specifically.
Background technology:
In recent years, fire frequently occurred in China, and it causes great threat to human life's property safety, and textiles industry and upholstery are that fire occurrence frequency is the highest.Equally, the pernicious gas discharged during flammable textile combustion is far longer than flame retardant textiles.And along with the raising of people's living standard, people not only can take into account the comfort level of fabric when selecting fabric, the fashion-orientation of fabric and functionalization etc. also can be considered.Therefore, multi-functional silk textile becomes study hotspot.
Silk is the natural protein fibre with individual styles such as moisture absorption are breathed freely, softness is smooth, gloss is soft, studies have reported that, with organophosphorous fire retardant, silk fabric is processed, the free formaldehyde content that the anti-flammability silk fabric obtained remains is higher, and the intensity of silk fabric also declines to some extent.
Summary of the invention:
The object of this invention is to provide a kind of preparation method of fire-retardant sensitization discoloration fabric, fire-retardant sensitization discoloration silk fabric prepared by the method, soft comfortable, limited oxygen index is up to more than 40%, and free formaldehyde is few, is conducive to environmental protection.
Object of the present invention is achieved through the following technical solutions:
A preparation method for fire-retardant sensitization discoloration silk fabric, comprises the following steps:
(1) preparation dips liquid: get sensitization discoloration powder, fire retardant, softener, crosslinking agent, catalyst and deionized water, and ultrasonic agitation is even, obtains dipping liquid;
(2) be immersed in by silk fabric and above-mentionedly dip in liquid, two leachings two are pricked, and pick-up is 80%-90%;
(3) take out silk fabric, with hot wash 2-3 time, then use cold water washing 2-3 time, 50-80 DEG C is dried 5-10min, 120-150 DEG C and bakes 2-5min, obtain fire-retardant sensitization discoloration silk fabric.
Preferred as technique scheme, the concentration dipping each component of liquid in described step (1) is sensitization discoloration powder 10-20g/L, fire retardant 30-60g/L, softener 10-15g/L, crosslinking agent 10-30g/L, catalyst 5-10g/L.
Preferred as technique scheme, fire retardant used in described step (1) is formaldehydeless phosphorus silicon fire retardant SP.
Preferred as technique scheme, in described step (1), crosslinking agent used is methacrylic acid acetoxyethyl AAEM.
Preferred as technique scheme, in described step (1), sensitization discoloration powder used is one in the middle of red, orange, yellow, green or mixes several.
Preferred as technique scheme, the limited oxygen index of the fire-retardant sensitization discoloration silk fabric that described step (3) obtains reaches more than 40%.
Beneficial effect of the present invention is: fire retardant under the effect of crosslinking agent and catalyst with silk fiber generation cross-linking reaction, fire retardant SP facilitates the catalytic dehydration of silk fiber, change thermal decomposition process Sum decomposition product, flame retardancy solid carbon is increased, imflammable gas reduces.Once the burning of flame-proof treatment silk fabric, carbon slag after burning forms thin and fine and close, smooth continuous carbon-coating on silk fabric surface, cover matrix surface, effectively can stop the supply of the transmission of free radical, the diffusion of imflammable gas and oxygen, thus stop matrix to burn further.And the fire retardant adopted and crosslinking agent are all the compounds of formaldehydeless environment-friendly type, make the silk fabric surface after arranging without free formaldehyde, be conducive to environmental protection.This method for sorting also adds sensitization discoloration powder, gives the color that silk fabric is changeable, meets the pursuit of numerous people to U.S..
