Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tissue product, and more particularly, to a soft and soft touch without increasing costs more than necessary. The present invention also relates to a tissue product using non-wood pulp. [0002] As is well known, facial tissues,
Tissue products such as toilet tissue and paper towels are required to have various functions and characteristics such as softness, good touch, and high water absorption. To satisfy these requirements, conventional softwood bleached pulp (NBK)
Virgin pulp such as P), hardwood bleached pulp (LBKP) has been mainly used. [0003] In recent years, the use of non-wood pulp fibers has been studied from the viewpoint of resource depletion and environmental problems, and the use of non-wood pulp has been increasing in the tissue field. [0004] Conversely, as the trend toward higher quality has recently been increasing, there has been an increasing demand for functions of high quality, such as softness and good touch, and aroma and deodorization. However, for example, when non-wood pulp of long fiber type such as hemp pulp is used for tissue paper,
Since the characteristics are significantly different from those of conventional NBKP and LBKP, mechanical strength and softness cannot be balanced, resulting in serious problems in operability and product flexibility. The use of such a chemical or the change of the manufacturing conditions raises problems such as increased costs. SUMMARY OF THE INVENTION An object of the present invention is to provide a tissue product which is soft and has an excellent touch feeling without increasing costs more than necessary. Means for Solving the Problems The inventors of the present invention have made intensive studies in view of the above, and as a result, have invented a tissue product of the present invention. That is, the tissue product of the present invention is mainly composed of hardwood bleached pulp (LBKP) and softwood bleached pulp (N
BKP), in a tissue product manufactured using pulp fibers composed of at least one virgin pulp selected from non-wood fiber pulp as a main raw material, 5 to 30% by mass of hemp pulp
Characterized by being used in the range of Hereinafter, a tissue product of the present invention will be described in detail. The tissue product of the present invention
It specifies the blending ratio of hemp pulp blended in a tissue product mainly produced from pulp fibers composed of at least one virgin pulp selected from LBKP, NBKP and non-wood fiber pulp. As the hemp pulp used in the present invention, any hemp pulp pulped by a conventionally known method can be used without any particular problem. As other virgin pulp, conventionally used pulp such as NBKP and LBKP, and conventionally known non-wood fiber pulp such as kenaf and bagasse can be used. In order to satisfy the properties such as tissue strength, softness, and feel,
Pulp freeness is appropriately selected and used in the range of 450 to 650 csf. In the present invention, the blending ratio of hemp pulp is 5 to 5.
It is specified in the range of 30% by mass. Hemp pulp is characterized by the average fiber length, and it is important to specify the blending ratio in order to take advantage of the characteristics. Here, if the blending ratio of hemp pulp is 5% by mass or less, the strength of hemp pulp cannot be secured, and it cannot be said that the characteristics are utilized. When the blending ratio of the hemp pulp is 30% by mass or more, the strength can be ensured, but the softness and the touch feeling are unfavorably deteriorated. In the present invention, if necessary,
Conventionally known paper strength agents, softeners, release agents, adhesives, fragrances,
Dyes and the like can be used. [0012] In the present invention, in the manufacture of tissue paper, as a tissue paper machine, a circular mesh,
Yankee machines such as short nets and twin wires can be used. On a Yankee dryer, wet crepe or dry crepe is applied, or after wet crepe is applied, base paper of tissue paper is obtained by further applying dry crepe. Thereafter, the base papers that have been appropriately cut are superimposed and subjected to a normal calendering process or the like to obtain a tissue product. The present invention will be specifically described below with reference to examples and comparative examples, but of course the present invention is not limited by these. In the examples, parts and% indicate parts by mass and mass%, respectively. The following are common to each of the examples and comparative examples. 1. Papermaking method For the papermaking, a circular mesh type paper machine was used, and the crepe ratio was 2
After dry creping at 4%, calendering was performed to obtain a 13.5 g / m 2 tissue base paper. At the time of papermaking, an epichlorohydrin-based wet paper strength agent (trade name: Caimen, manufactured by Dick Hercules Co., Ltd.) was used as a paper strength enhancer at 0.1% by mass per pulp, and polyethylene oxide (trade name; AL) was used as a water-squeezing improver. Cox, manufactured by Meisei Chemical Industry Co., Ltd.) was added in an amount of 0.005% by mass per pulp. Further, two sheets of base paper were overlapped with a rewinder such that the Yankee surface side was outside, and the product was processed through a processing machine. 2. Hemp pulp In the present invention, hemp pulp made by Toho special pulp was used as hemp pulp. In the table, LBKP is “L”, N
BKP is described as "N" and hemp pulp is described as "A". 3. Evaluation Method 1) Feeling of Touch (Softness) The evaluation of the feeling of touch was carried out by at least 10 judges in five stages of evaluation. The evaluations of each judge were totaled and re-evaluated into five levels of ◎ (good), △, Δ, ×, xx (bad). In addition, it described as "sensory evaluation" in the table. 2) Operability The operability was evaluated by comprehensively judging the occurrence of paper breakage during papermaking and the workability during threading. Evaluation is ◎
(Good), △, Δ, ×, XX (bad).
X: Below the rating, it is judged that the product cannot be practically produced. [0018] Example 1 LBKP90 parts were mixed with 10 parts of hemp pulp, using as regulating forms pulp as the pulp freeness 580Csf, a material obtained by papermaking so that the basis weight of 13.5 g / m 2 2
The sheets were superposed to obtain a tissue base paper. Example 2 A product was prepared in the same manner as in Example 1 except that 95 parts of LBKP and 5 parts of hemp pulp were used. Example 3 A product was made in the same manner as in Example 1 except that 80 parts of LBKP and 20 parts of hemp pulp were used. Example 4 A product was prepared in the same manner as in Example 1 except that 70 parts of LBKP and 30 parts of hemp pulp were used. Example 5 A product was produced in the same manner as in Example 1 except that 75 parts of LBKP, 15 parts of NBKP and 10 parts of hemp pulp were used. Example 6 A product was produced in the same manner as in Example 1 except that 65 parts of LBKP, 25 parts of NBKP and 10 parts of hemp pulp were used. Comparative Example 1 In Example 1, 100 parts of LBKP and 0 hemp pulp
The paper was produced in the same manner as in Example 1 except that the part was used. However, the strength was insufficient, and the paper was frequently broken, and stable operation could not be performed. For this reason, only the amount required for evaluation was paper-made, and was not made into a product. Comparative Example 2 A paper was produced in the same manner as in Example 1 except that 97.5 parts of LBKP and 2.5 parts of hemp pulp were used. I couldn't. For this reason, only the amount required for evaluation was paper-milled and not a product. Comparative Example 3 A product was produced in the same manner as in Example 1 except that 60 parts of LBKP and 40 parts of hemp pulp were used. Reference Example 1 A product was produced in the same manner as in Example 1 except that 60 parts of LBKP and 40 parts of NBKP were used. The tissue products obtained in Examples 1 to 6 and Comparative Examples 1 to 3 and Reference Example 1 were evaluated by the above evaluation methods. The results are shown in Table 1 below. [Table 1] Evaluation Results Reference Example 1 represents a general formulation and operating conditions for reference. As shown in Table 1, all Examples showed good sensory evaluation results equal to or higher than those of Reference Example 1. In Example 3, although the operability was lowered, it was within an acceptable range. On the other hand, in Comparative Examples, Comparative Examples 1 and 2 showed a better sensory evaluation than Reference Example 1, but the operability was extremely deteriorated due to insufficient strength, and products could not be obtained. However, the overall evaluation was not good. In addition, when the blending amount of hemp pulp is increased beyond the range limited by the present patent as in Comparative Example 3, the operability is improved, but the sensory evaluation such as touch is reduced, and at least the functionality is improved. In terms of points it was not a good approach. As described above, none of the comparative examples received a better evaluation than the examples. As described above, the tissue product of the present invention is a tissue product manufactured mainly from pulp fibers composed of at least one virgin pulp selected from LBKP, NBKP and non-wood fiber pulp. By specifying the blending ratio of the hemp pulp to be blended, the softness and the feeling of touch can be improved without unnecessarily increasing the cost.
