Abstract

Disclosed in the present invention is an aqueous impregnated base fabric and a preparation method thereof. The aqueous impregnated base fabric is prepared by impregnating and sizing the base fabric with an aqueous PVA slurry in a slurry groove and then further drying, wherein the aqueous PVA slurry is an aqueous PVA resin solution with a mass content of 3%-5%. Imitation leather made of the impregnated base fabric of the present invention not only has a better mechanical air permeability but also has a better hand feel, and is closer to real leather.

Description

一种水性含浸基布及其制备方法 技术领域  Aqueous impregnated base fabric and preparation method thereof
本发明属于合成革制造领域， 具体涉及水性合成革用水性含浸基布以及 这种水性含浸基布制备方法。  The invention belongs to the field of synthetic leather manufacturing, and particularly relates to an aqueous impregnated base fabric for aqueous synthetic leather and a preparation method of the aqueous impregnated base fabric.
背景技术 Background technique
透气、透湿性是合成革产品永恒追求的目标，通过对合成革基布进行 PVA 浸渍处理， 在纤维表面形成一层薄膜， 在制革过程中形成了阻隔层， 当 PVA 被水洗掉后， 在纤维和 PU之间便形成了空隙， 从而赋予成品更好的透气、透 湿性以及更柔软的手感。 但是在现有技术中同时兼具透气、 透湿、 柔软、 耐 磨等特性的合成革产品仍难在满足大规模工业生产的需要。  Breathability and moisture permeability are the eternal pursuit of synthetic leather products. By impregnating the synthetic leather base fabric with PVA, a film is formed on the surface of the fiber, and a barrier layer is formed during the tanning process. When the PVA is washed away by water, A void is formed between the fiber and the PU to give the finished product a better breathability, moisture permeability and a softer hand. However, in the prior art, synthetic leather products which are both breathable, moisture permeable, soft, and abrasion resistant are still difficult to meet the needs of large-scale industrial production.
发明内容  Summary of the invention
本发明的目的是提供一种水性 PVA含浸基布。  It is an object of the present invention to provide an aqueous PVA impregnated base fabric.
本发明的另一目的是提供一种上述水性 PVA含浸基布的制备方法。  Another object of the present invention is to provide a process for preparing the above aqueous PVA impregnated base fabric.
本发明的目的可以通过以下措施达到：  The object of the invention can be achieved by the following measures:
一种水性含浸基布，其由水性 PVA浆料在浆料槽中与基布进行浸渍上浆 并进一歩烘干后制成， 其中所述水性 PVA浆料为质量含量为 3〜5%的 PVA 树脂水溶液。  An aqueous impregnated base fabric prepared by impregnating and sizing an aqueous PVA slurry with a base fabric in a slurry tank, wherein the aqueous PVA slurry is a PVA resin having a mass content of 3 to 5%. Aqueous solution.
PVA 化学名称为聚乙烯醇， 为白色固体， 主要根据聚合度来选择， 为了 便于生产水洗一般选择聚合度低， 低温易溶型。 本发明特别选用韩国东洋化 学有限公司的 P17型树脂粉。 进一歩的， 水性 PVA浆料中 PVA树脂的质量 含量为 4%。  The chemical name of PVA is polyvinyl alcohol, which is a white solid. It is mainly selected according to the degree of polymerization. In order to facilitate the production of water washing, it is generally selected to have a low degree of polymerization and a low-temperature soluble type. In the present invention, P17 type resin powder of Korea Toyo Chemical Co., Ltd. is specifically selected. Further, the PVA resin in the aqueous PVA slurry has a mass content of 4%.
本发明还公开了一种上述水性含浸基布的制备方法，先将 PVA树脂粉在 水中搅拌溶解至完全透明的水性 PVA浆料溶液，再将该溶液移入浆料槽中与 基布进行浸渍上浆， 最后烘干。 其中水性 PVA浆料溶液中 PVA树脂的质量 含量为 3〜5%， 优选为 4%。 The invention also discloses a preparation method of the above aqueous impregnated base fabric, which firstly dissolves the PVA resin powder in water to a completely transparent aqueous PVA slurry solution, and then moves the solution into the slurry tank to perform immersion sizing with the base cloth. , finally dry. The quality of PVA resin in aqueous PVA slurry solution The content is 3 to 5%, preferably 4%.
在制备方法中 PVA树脂采用韩国东洋化学有限公司的 P17型 PVA树脂 粉。 为防止浆料因高温变黄以及增加透气性， 烘干温度需为 130-140°C， 浸 渍上浆过程中水性 PVA浆料的上浆量根据烘干前后的含浸基布克重测试，以 上浆量 9-10克 /m2为最佳。 In the preparation method, the PVA resin was P17 type PVA resin powder of Toyo Chemical Co., Ltd. of Korea. In order to prevent the slurry from yellowing due to high temperature and increasing the gas permeability, the drying temperature should be 130-140 ° C. The sizing amount of the aqueous PVA slurry during the immersion sizing process is tested according to the immersion base cloth weight before and after drying. 9-10 g/m 2 is the best.
本发明的含浸基布经过制革水洗后用于生产服装革、 沙发等， 具有较佳 的透气性， 且产品手感较软， 更接近真皮。  The impregnated base fabric of the present invention is used for the production of garment leather, sofa, etc. after being washed by tanning, and has better air permeability, and the product feels softer and closer to the leather.
具体实施方式 detailed description
实施例 1 Example 1
先在常温水中进行搅拌，根据比例按照 P17粉 4%的质量浓度边搅拌边将 PVA 慢慢倒入， 直至搅拌至完全透明溶液状， 将浆料放入上浆槽中， 通过开 布机进行浸渍上浆， 上浆量 9-10克 /m2， 最后于 130-140°C下烘干。 First, stir in normal temperature water, and pour the PVA slowly according to the ratio of 4% mass concentration of P17 powder until it is stirred until it is completely transparent. Put the slurry into the sizing tank and pour it through the cloth machine. Sizing, sizing amount 9-10 g / m 2 , and finally drying at 130-140 ° C.
对所制备的水性含浸基布采用 BRANCA IDEALAIR公司的 4PD型透气 仪在常温常湿下测试， 该布的透气量为 41L/mm。 对所制备的水性含浸基布 在恒温恒湿箱内利用杯式法的测试原理进行渗透进入透湿杯增重法测试， 结 果显示该布的 24h透湿量为 39.6g/m2。 The prepared aqueous impregnated base fabric was tested under normal temperature and humidity using a BPDCA IDEALAIR 4PD type gas permeable apparatus, and the air permeability of the cloth was 41 L/mm. The prepared aqueous impregnated base fabric was infiltrated into the moisture permeable cup weighting method by the cup method in the constant temperature and humidity chamber, and the results showed that the cloth had a moisture permeability of 39.6 g/m 2 at 24 h.
