摘要： PURPOSE: Provided is a process of preparing paper which allows low damage of cotton fibers during paper making, is improved in the folding endurance in the cross direction, has excellent dimension stability in high pressure printing and is improved in printability. Whereby, the product is effectively used in paper requiring high precision printing. CONSTITUTION: A cotton yarn is beaten until a beating degree becomes 18 to 20 degree SR and then refined until a beating degree becomes 40 to 60 degree SR to produce pulp having a fine fiber content of 40% or less, which is added with 5 to 10 parts by weight of an organic/inorganic filler and 0.3 to 0.5 parts by weight of a wet strength agent, based on 100 parts by weight of pulp to produce base paper, which is soaked in a mixed solution of 2 to 5% by weight of polyvinyl alcohol, 0.1 to 1.0% by weight of a wet strength agent, 1.0 to 5.0% by weight of urea and 0 to 10% by weight of glycerin and then passed through a compression roll. Thereafter, the treated paper is soaked in a mixed solution of 2 to 5% by weight of borax and 2 to 5% by weight of glycerin, passed through a compression roll and dried.
摘要翻译：目的：提供一种在造纸过程中对棉纤维造成低损害的纸张的制备方法，在横向上的耐折性得到改善，在高压印刷中具有优异的尺寸稳定性，并提高了可印刷性。因此，该产品有效地用于需要高精度印刷的纸张中。构成：将棉纱殴打直至打浆度达到18〜20度SR，然后精制直至打浆度达到40〜60度SR，生成细纤维含量为40％以下的纸浆，添加5〜 10重量份的有机/无机填料和0.3-0.5重量份的湿强度剂，基于100重量份的纸浆生产原纸，将其浸渍在2至5重量％的混合溶液中的聚乙烯醇，0.1〜1.0重量％的湿强力剂，1.0-5.0重量％的尿素和0-10重量％的甘油，然后通过压缩辊。然后，将经处理的纸浸渍在2〜5重量％的硼砂和2〜5重量％的甘油的混合溶液中，通过压缩辊并干燥。
