A kind of preparation method and application of kapok fiber non-woven mask substrate

Abstract

The invention provides a preparation method and application of a kapok fiber non-woven mask base material, belonging to the field of skincare. The preparation method of the kapok fiber non-woven mask base material, provided by the invention, comprises the following steps: a. carrying out light-alkali partial degreasing treatment on kapok fiber; b. carrying out hollowness degree recovery and softening treatment on the kapok fiber damaged to flat tape shape in the pretreatment process; c. carrying out dehydration drying treatment on the kapok fiber so as to obtain kapok fiber with good spinnability; d. carrying out opening and mixed carding on the kapok fiber to obtain a kapok fiber web; e. carrying out reinforcement treatment on the kapok fiber web by adopting a high-pressure spray method; f. drying the kapok fiber web after reinforcement treatment to obtain the kapok fiber non-woven mask base material. Kapok fiber with high degree of hollowness is adopted for the kapok fiber non-woven mask base material provided by the invention; in use, water absorbed in the fiber cavity can be slowly released, and thus the mask has good moisturizing and water locking effects, is light in gram weight, soft in hand feeding and good in fitness, and further is good in application prospect.

Description

technical field [0001] The invention belongs to the field of beauty and skin care, and relates to a preparation method and application of a mask base material, in particular to a preparation method and application of a kapok fiber non-woven mask base material made of kapok fiber. Background technique [0002] Kapok fiber is developed and produced by the inner wall cells of the kapok capsule shell. Because the kapok fiber has little adhesion on the inner wall of the capsule shell, the fibers are easy to separate, unlike cotton, which has to be ginned to remove cotton seeds. Kapok fiber is a single-cell fiber with a cylindrical appearance, smooth surface, and almost no twist. The middle section of the kapok fiber is thicker and the tip is thinner. It is a hollow fiber with both ends closed, and the hollowness is as high as 80%-90%. , while the hollowness of general synthetic fibers only reaches 35-40% of the total volume. Such a high hollowness makes the kapok cell wall thin, ...

[0003] The test and analysis of the compression performance of kapok wadding is introduced in the article on the test of the compression performance of a new type of kapok wadding manufactured with patented technology. The performance is not as good as that of pure kapok wadding, but the compression elasticity of the new kapok / synthetic fiber blended wadding has been significantly improved [Lou Ying, Wang Fumei, Liu Wei, etc. Analysis of compression properties of kapok wadding[J]. Textile Journal of the Chinese Academy of Sciences, 2007,28(1):10-13.]; The influence of blending ratio on the performance of kapok-cotton blended yarn introduces the test of properties such as tensile properties, evenness CV, and hairiness of kapok-cotton blended yarns with different blending ratios Index, shows: with the increase of kapok fiber content, performance indicators such as the strong elongation performance of blended yarn, hairiness, evenness CV all show a downward trend, when the kapok fiber content is lower than 30%, the breaking strength of blended yarn decreases The range is small; when the kapok fiber content exceeds 50%, the elongation at break of the blended yarn decreases significantly [Yang Li, Bi Songmei, Hong Jun, etc. Effect of blending ratio on the properties of kapok-cotton blended yarns [J]. Cotton Textile Technology, 2013,41(1):30-32.]; The development and wearing performance research of blended fabrics of cotton and kapok. This paper introduces the blended yarn with kapok as the main body, designs 9 kinds of different structures, and tests the warmth retention of plants. , air permeability, drape, abrasion resistance, and wrinkle resistance, which indicate that cotton and kapok blended fabrics have the best warmth retention and air permeability, and can be used in the development of clothing fabrics [Qi Meng, Shen Lanping. Development and development of cotton and kapok blended fabrics Wearing performance research [J]. Cotton Textile Technology, 2013,41(12):9-11.]; Research on kapok sizing process This paper introduces the method of sizing and optimizing the size components to overcome the length of kapok fiber. Short, high torsional rigidity and the impact on spinning and weaving process [Cao Chenxiao. Research on kapok sizing process [J]. Shanghai Textile Science and Technology, 2012,40(10):6-7.]; Pretreatment of kapok textiles Conditions Exploration The article introduces the best process of scouring kapok-containing blended yarn with NaOH-containing treatment agent [Wang Qian, Hu Lixia, Yan Xiaofei, etc. Exploration of pre-treatment conditions of kapok textiles [J]. Dyeing and Finishing Technology, 2014, (7): 19-20.]; Dyeing status and development of kapok fiber This paper comprehensively analyzes the dyeing status of kapok fiber, and shows that the dyeing rate of direct dyes to kapok fiber can reach more than 80%, and the activity The dye uptake rate of kapok fibers by dyes is about 50%. Through the dyeing effect of salt, the dye uptake rate of reactive dyes to cationic modified kapok fibers can reach 90%[Gao Qunyan, Ding Ying, Jiang Tao, etc. Dyeing status and development[J].Journal of Shanghai University of Engineering Technology,2013,27(2):141-146]

[0004] It can be seen from the aforementioned information that, in addition to the original use of cotton wool, modern textile technology has successfully used kapok in spinning, weaving, finishing and clothing fabrics. In the subsequent processing, it needs to go through all the technological processes of spinning, weaving and dyeing, among which the carding and drafting of spinning, sizing, NaOH degreasing and dyeing have different degrees of damage to kapok fiber. Damage, because the cell wall of kapok is thin and hollow, after the above process, most of the cell wall of kapok ruptures, and the cell fibers before the rupture are in the form of airbags, and the fibers after rupture are in the shape of flat ribbons [Li Suying, Wang Hongyun, Xiong Dingguo et al. Research on the properties of kapok fiber nonwoven materials [J]. Industrial Textiles, 2011, 29(7): 16-19.], thus losing the advantages of kapok fiber's high hollowness and light weight, the existing The method of maintaining the high hollowness of kapok or the method of restoring the hollowness of kapok fiber is also relatively complicated [Donghua University. A textile post-processing method for restoring the hollowness of kapok fiber: China, CN201410146510.X[P].2014-7- 23.][Donghua University. A processing method of kapok yarn with high and high hollowness: China, CN201010537934.0[P].2011-3-2.], thus developing a short process, less damage to fibers, It is very important to make full use of the high and high hollowness characteristics of kapok and produce high-end products accordingly
