Description
技术领域technical field
本发明涉及美容护肤领域，特别涉及一种无纺面膜基布及其制备方法。The invention relates to the field of beauty and skin care, in particular to a non-woven facial mask base fabric and a preparation method thereof.
背景技术Background technique
面膜是美容行业经常使用的一种护肤用品，具有使用方便、见效快、护肤效果好等特点，因而非常受女性朋友的喜爱。面膜按照材质分类，可分为生物纤维面膜、泥膜、凝胶面膜以及以无纺布为基材的面膜，其中无纺布面膜是先采用纤维制成无纺布面膜基布，然后再浸渍含有多种成分的营养液，经灌装封口后制成，使用时从灌装袋中拿出无纺布面膜直接贴在脸部即可，非常随性，且在任意场合均可使用，已经成为市场上最受欢迎的脸部护理产品。Mask is a kind of skin care product often used in the beauty industry. It has the characteristics of convenient use, quick effect, and good skin care effect, so it is very popular among female friends. According to the classification of materials, masks can be divided into biological fiber masks, mud masks, gel masks and masks based on non-woven fabrics. Among them, non-woven masks are made of fibers to make non-woven mask base fabrics, and then impregnated The nutrient solution containing multiple ingredients is made after filling and sealing. When using it, take out the non-woven mask from the filling bag and stick it directly on the face. It is very casual and can be used on any occasion. Become the most popular face care product on the market.
用于制作面膜基布的无纺布主要有水刺法无纺布、纺粘法无纺布和针刺法无纺布，其中水刺法无纺布具有手感软、悬垂性好、外观与传统纺织品最接近等性能而在面膜行业非常受欢迎。水刺法无纺布按照成网方式主要分为交叉铺网、半交叉和直接成网法三大类，其中交叉铺网和半交叉法水刺布纵、横向强力比较接近，但偏向于厚克重产品，直接成网法水刺布纵、横向强力差异较大，但偏向于薄克重产品。因为面膜在使用时对基布的纵、横向强力均有要求，因而交叉铺网和半交叉法水刺布是面膜基布的首选。近两年来，市场开始流行贴服、薄、轻、透的面膜，而交叉铺网和半交叉法难以生产30g/m2以下的水刺布，因此市场需求开发薄克重水刺无纺布，非常必要。The non-woven fabrics used to make mask base fabrics mainly include spunlace non-woven fabrics, spunbond non-woven fabrics and needle-punched non-woven fabrics. Among them, spunlace non-woven fabrics have soft hand feeling, good drapability, and similar appearance. Traditional textiles are the closest to such properties and are very popular in the mask industry. Spunlace non-woven fabrics are mainly divided into three categories: cross-laid, semi-crossed and direct-laid methods according to the netting method. Among them, cross-laid and semi-crossed spunlace fabrics are relatively close in longitudinal and transverse strength, but tend to be thicker. For grammage products, the vertical and transverse strengths of spunlaced fabrics by direct forming method are quite different, but they tend to be thinner grammage products. Because the mask has requirements for the longitudinal and lateral strength of the base fabric when it is used, cross-laying and half-cross method spunlace fabrics are the first choice for mask base fabrics. In the past two years, the market has become popular for sticky, thin, light and transparent masks. However, it is difficult to produce spunlace fabrics below 30g/m2 by cross - laying and semi-crossing methods. Therefore, the market needs to develop thin gram-weight spunlace non-woven fabrics. Very necessary.
现有采用水刺法无纺布作为面膜基布的资料主要有：The existing materials that use spunlace non-woven fabrics as mask base fabrics mainly include:
专利CN201410847297.5公开一面吸水渗透一面防水锁水贴肤无纺布，采用细度小于等于0.9分特的5-15毫米纤维素纤维与PP疏水层水刺复合而成，由于采用细旦短纤纤维素纤维作为吸水层，底层为疏水的PP纺粘布，该纺粘布阻挡了真空抽吸时对高压水流的抽吸力，水刺加固时容易使细旦短纤纤维素纤维被高压水冲走，生产效率较低。Patent CN201410847297.5 discloses a water-absorbing and penetrating side and a waterproof and water-locking non-woven fabric, which is composed of 5-15 mm cellulose fibers with a fineness of less than or equal to 0.9 decitex and PP hydrophobic layer spunlace. The cellulose fiber is used as the water-absorbing layer, and the bottom layer is a hydrophobic PP spunbond cloth. The spunbond cloth blocks the suction force of the high-pressure water flow during vacuum suction, and the fine-denier short-fiber cellulose fiber is easily absorbed by the high-pressure water during spunlace reinforcement. Washed away, the production efficiency is lower.
专利CN201310277517.0公开一种珍珠纤维与粘胶纤维组合水刺无纺布的生产工艺，采用珍珠纤维和粘胶纤维为原料，依次进入开松、梳理、铺网、牵伸、水刺、烘干、在线检测、卷取和分切工序后而制成，由于两台梳理机喂入纤网克重均为30g/m2，因此成品平均克重≥60 g/m2；专利CN200810029962.4公开一种弹性面膜布，采用直接成网法水刺无纺布加工工艺制成，该弹性面膜布含有复合超细短纤维、脱脂棉或竹纤维，具有一定的弹力回复性，制成的水刺基布克重在60-100 g/m2之间。上述两项专利涉及的无纺布在用作面膜基布时，由于无纺布克重较大，会影响其对脸部皮肤的贴合性。Patent CN201310277517.0 discloses a production process of pearl fiber and viscose fiber combined spunlace non-woven fabric, using pearl fiber and viscose fiber as raw materials, followed by opening, carding, web laying, drafting, spunlace, drying It is made after drying, on-line inspection, coiling and slitting processes. Since the weight of the fiber web fed by the two carding machines is 30g/m 2 , the average weight of the finished product is ≥60 g/m 2 ; patent CN200810029962.4 Disclosed is an elastic facial mask cloth, which is made by direct web-forming spunlace non-woven fabric processing technology. The elastic facial mask cloth contains composite ultrafine short fibers, absorbent cotton or bamboo fibers, and has certain elastic recovery properties. The spunlace fabric made The base weight is between 60-100 g/m 2 . When the non-woven fabric involved in the above two patents is used as the base fabric of the facial mask, due to the large grammage of the non-woven fabric, it will affect its fit to the facial skin.
专利CN201410339416.6公开一种快速可吸收性纯天然真丝面膜，是以纯蚕丝短纤维为原料，采用水刺成网技术制备真丝无纺布，经过预处理后，将真丝无纺布浸入面膜营养液中而制成；专利CN201410370820.X提供一种甲壳素无纺布，由含有5-90重量份的甲壳素纤维和10-95重量份的其它纤维，混合后通过水刺、针刺、热压工艺制得甲壳素无纺布，具有保护皮肤清洁健康的功效。上述专利均强调了面膜基布的功能性，并未涉及轻薄型及其与面部的贴合性问题。Patent CN201410339416.6 discloses a fast-absorbable pure natural silk mask, which uses pure silk short fiber as raw material and adopts spunlace technology to prepare silk non-woven fabric. After pretreatment, the silk non-woven fabric is immersed in the mask nutrient solution Made in China; patent CN201410370820.X provides a chitin non-woven fabric, which is composed of chitin fibers containing 5-90 parts by weight and other fibers of 10-95 parts by weight, mixed by water entanglement, needle punching, hot pressing The chitin non-woven fabric is prepared by the process, which has the effect of protecting the skin clean and healthy. The above-mentioned patents all emphasize the functionality of the base fabric of the mask, and do not involve the light and thin type and its fit with the face.
可以看出，专利资料中公开的无纺面膜基布存在加工效率低实现难度大、克重较大贴服性不好的问题，或者是偏向于强调面膜基布的功能性。由于面膜属于一种时尚产品，需要跟随市场潮流而变化才能引起消费者的购买欲望，而面对现今市场对薄透、贴合性好的面膜需求，无纺面膜基布也必须要进行针对性开发。It can be seen that the non-woven mask base fabric disclosed in the patent materials has the problems of low processing efficiency, high difficulty in realization, heavy weight and poor fit, or tends to emphasize the functionality of the mask base fabric. Since the mask is a fashion product, it needs to follow the market trend to arouse consumers' desire to buy. In the face of the current market demand for thin, transparent and good-fitting masks, non-woven mask base fabrics must also be targeted. develop.

表1：无纺面膜基布性能的测试结果Table 1: Test results of properties of non-woven mask base fabric
从表1可以看出，实施例2-4制备的无纺面膜基布在吸水性、透明性、柔软性、透气性能方面都比现在市场上销售的普通面膜基布表现突出，特别是透明度，比普通面膜基布高出近一倍，原因是采用了吸水后透明性非常好的铜氨纤维和天丝A100；在透气性方面，实施例2-4的透气性平均值要比普通面膜基布高出90.6%，主要是聚乙烯醇纤维溶除后在布面上留下了许多不规则小孔隙的缘故，导致透气性大大增加；此外，在柔软性方面，实施例2-4的柔软性平均值要比普通面膜基布低70.2%，柔软性数值越小，基布越柔软，与脸部的皮肤贴服性越好，可见本发明提供的无纺面膜基布的制备方法制备的面膜基布非常柔软。本发明制备的无纺面膜基布中纤维间隙和毛细孔隙多，松软而蓬松，轻薄而悬垂，表面布满了不规则的孔隙，更增加了其吸水性、透气性以及保湿贴服性，可以在任何场合随意使用，是美容面膜的理想基布，完全适应了爱美女性对时尚的追求。As can be seen from Table 1, the non-woven facial mask base fabric prepared by Example 2-4 is more prominent than the common facial mask base fabric sold in the market now in terms of water absorption, transparency, softness and air permeability, especially the transparency. It is nearly twice as high as the ordinary mask base fabric, because the cupro ammonia fiber and Tencel A100 with very good transparency after absorbing water are used; in terms of air permeability, the average value of the air permeability of Examples 2-4 is higher than that of ordinary mask base fabrics. The cloth is higher than 90.6%, mainly because polyvinyl alcohol fiber leaves the reason of many irregular small pores on the cloth surface after dissolving, and causes air permeability to increase greatly; In addition, in softness, the softness of embodiment 2-4 The average value of softness is 70.2% lower than that of ordinary facial mask base cloth. The smaller the softness value is, the softer the base cloth is, and the better the skin adhesion with the face is. It can be seen that the preparation method of the non-woven facial mask base cloth provided by the present invention is prepared The base fabric of the mask is very soft. The non-woven facial mask base cloth prepared by the present invention has many fiber gaps and capillary pores, is soft and fluffy, thin and drapes, and the surface is covered with irregular pores, which further increases its water absorption, air permeability and moisturizing and sticking properties. It can be used casually on any occasion, and it is an ideal base fabric for beauty masks, fully adapting to the fashion pursuit of beauty-loving women.
