Abstract
The invention discloses a method for preparing rose-fragrance leather, which comprises the following steps of: rewetting retanned, dyed and fat-stuffed leather in a mass ratio of leather to water of 1:(7.5-10) at the temperature of between 30 and 40DEG C and a rate of 600-800r/min for 6 to 8 hours; and regulating the pH of a system to be 5-7 by using a solution of sodium bicarbonate, adding rose essence capsules in a mass ratio of essence to leather of (3-8):1, heating the system to the temperature of between 40 and 60DEG C, increasing fragrance for 6 to 9 hours when a rotating speed is 600-1,200r/min, taking the fragrance-increased leather out, and airing naturally to obtain the rose-fragrance leather. The rose-fragrance leather has the essence utilization rate of 34.92 percent, has obvious rose fragrance, still has obvious rose fragrance after 40 days, and has good fragrance sustained-release property.
Description
Technical field
The present invention relates to a kind of rose scent leather and preparation method thereof, specifically relate to the preparation method who adopts wet complete processing to process a kind of rose scent leather.
Background technology
Leather industry and people live closely bound up, and in recent years, fragrant leather has become one of development trend of functional leather.It is the effective means that improves product specification and added value that fragrance is combined with leather, also is the joint demand of human consumer and leather industry.Fragrance leather pleasant aroma, class height can be used on the products such as automobile cushion leather, sofa artificial leather, clothing leather, luggage leather, and extremely vast market is arranged.Rose compound is a kind of important additive, liked by the human consumer, is mainly used at present in the daily necessities such as weaving, leather, and the quality of end product is played crucial effects.The conventional leather perfuming is directly essence to be sprayed at the finished leather surface, but easily causes the surface inhomogeneous, shortcomings such as color spot.
Summary of the invention
The present invention provides a kind of preparation method of rose scent leather in order to solve above-mentioned technical problem, the rose scent leather of this method preparation has feature rose fragrance, and whole pleasant aroma has fragrance slow release effect preferably.
Technical scheme of the present invention
A kind of preparation method of rose scent leather, its preparation process process flow diagram as shown in Figure 1, be about to leather and weigh that to add that a certain amount of water termostat stirs behind the certain hour with lye pH adjustment be 5~7 in the back, add a certain amount of rose essence capsules subsequently, carry out constant temperature again and stir to take out behind the certain hour and dry, promptly get a kind of rose scent leather in natural ventilation place.Its concrete preparation process comprises the steps:
(1), with the leather behind the retanning dyeing and fat-liquoring, the mass ratio of control leather and water is m
Leather: m
WaterFor returning wet treatment in 1:7.5~10, be 30~40 ℃ in temperature, when rotating speed is 600~800 r/min, return wet 6~8h, get system 1;
Described leather is ox-hide, sheepskin or pigskin;
(2), be that the pH of the system 1 of 0.5% sodium hydrogen carbonate solution regulating step (1) gained is 5~7 with massfraction, add rose essence capsules subsequently, the mass ratio of control rose essence capsules and leather, i.e. m
Essence: m
LeatherBe 3~8:1, get system 2, system 2 is warming up to 40~60 ℃, rotating speed is 600~1200 r/min, behind perfuming 6~9h leather taking-up behind the perfuming is dried in natural ventilation place, promptly gets a kind of rose scent leather.
Beneficial effect of the present invention
A kind of rose scent leather of the present invention owing to adopt wet complete processing to be prepared, to the leather perfuming, makes essence capsule directly infiltrate collagen inside in the wet workshop section that processes, and can effectively improve the slow release effect of essence.The essence utilization ratio of the rose scent leather of preparation is up to 34.92%, and fragrance is mellow and full pleasant, and rose fragrance is remarkable, can effectively improve the former scent of of leather; After placing in 40 days, the rose fragrance of rose scent leather is still more remarkable, and fragrance does not have considerable change, has good fragrance slow-releasing.
A kind of rose scent leather of the present invention has reduced the leather peculiar smell, makes leather give out light pleasant fragrance for a long time, can significantly improve leather quality and class, has also played certain function of health care.
