Preparation method and application of kapok fiber non-woven mask base material

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 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 35-4O% of the total volume. Such a high hollowness makes the kapok cell wall thin, go...

[0003]Analysis of the compressive properties of kapok batting This article introduces the test of the compressive properties of the new kapok batting made with patented technology, and shows that after mixing synthetic fibers Although the initial bulkiness of kapok wadding is not as large as that of purified fiber wadding, and its softness is not as good as that of pure kapok wadding, the compression elasticity of the new kapok / synthetic fiber blended wadding has been significantly improved [Lou Ying, Wang Fumei, Liu Wei etc.. Test and analysis of compression properties of kapok floc [J]. Textile Journal, 2007, 28 (1): 10-13.]; The influence of blending ratio on the performance of kapok-cotton blended yarn introduces the test of different blending ratios of kapok-cotton The performance indicators such as tensile properties, evenness CV, and hairiness of blended yarns show that: with the increase of kapok fiber content, the performance indicators such as tensile properties, hairiness, and evenness CV of blended yarns all show a downward trend. When the fiber content is less than 30%, the breaking strength of the blended yarn decreases slightly; when the kapok fiber content exceeds 50%, the elongation at break of the blended yarn decreases significantly [Yang Li, Bi Songmei, Hong Jun, etc. Blending ratio of kapok Influence of cotton blended yarn properties[J].Cotton Textile Technology,2013,41(1):30-32.];The development of blended fabrics of cotton and kapok and the research on wearability. Nine different textures were designed for the yarn, and the warmth retention, air permeability, drapability, wear resistance, and wrinkle resistance of the plants were tested, and it was shown that the cotton kapok blended fabric has the best warmth retention and air permeability, and can be used for the development of clothing fabrics [Qi Meng, Shen Lanping. Research on the development and wearability of cotton and kapok blended fabrics [J]. Cotton Textile Technology, 2013, 41(12): 9-11.]; The method of optimizing the size components to overcome the influence of kapok fiber length and high torsional stiffness on the spinning and weaving process [Cao Chenxiao. Research on kapok sizing process[J]. Shanghai Textile Science and Technology, 2012,40 (10):6-7.]; Exploration of the pretreatment conditions of kapok textiles This article introduces the best process of scouring the kapok-containing blended yarn with a treatment agent containing NaOH [Wang Qian, Hu Lixia, Yan Xiaofei, etc. Exploration of the pretreatment conditions of kapok textiles [J]. Dyeing and Finishing Technology, 2014, (7): 19-20.]; Dyeing status and development of kapok fiber A comprehensive analysis of the dyeing status of kapok fiber is carried out in this paper, showing that: directly The dye uptake rate of kapok fibers by dyes can reach more than 80%, and the dye uptake rate of reactive dyes on kapok fibers is about 50%. Through the dyeing effect of salt, the dye uptake rate of reactive dyes on kapok fibers after cationic modification can reach 90%[Gao Qunyan, Ding Ying, Jiang Tao, etc. Dyeing status and development of kapok fiber[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 In the fabric, however, because the kapok fiber is short, has no curl, and there are many impurities such as fat wax on the surface, it needs to go through all the technological processes of spinning, weaving and dyeing in the subsequent processing, among which the carding and drafting of spinning, pulping, etc. Yarn, NaOH degreasing, dyeing, etc. have different degrees of damage to the kapok fiber. Because the cell wall of kapok is thin and hollow, after the above process, the cell wall of most kapok ruptures, and the cell fibers before the rupture appear The structure of the airbag, the fibers are flat ribbons after rupture [Li Suying, Wang Hongyun, Xiong Dingguo, etc. Research on the properties of kapok fiber nonwoven materials [J]. Industrial Textiles, 2011,29(7):16-19.], thus losing the kapok The advantages shown by the fiber's high hollowness and light weight, the existing methods of maintaining the high hollowness of kapok fibers or restoring the hollowness of kapok fibers are also relatively complicated [Donghua University. A post-processing of textiles that restores the hollowness of kapok fibers Method: China, CN201410146510.X[P]. 2014-7-23.][Donghua University. A processing method of kapok yarn with high hollow ratio: China, CN201010537934.0[P]. 2011-3-2. ], so it is very important to develop a method with short process, little damage to fibers, which can make full use of the characteristics of kapok's high and high hollowness, and correspondingly produce high-grade products
