Embodiment 1

[0087] Preparation of the sizing agent composition: 17.56 parts of polyisocyanate, 96.2 parts of diol, 17.86 parts of polyol (A), and 54.96 parts of filler were added to obtain mixed liquid A. Further, 0.014 parts of the catalyst (A) was added to 100 parts of the mixed liquid A and mixed to prepare a sizing agent composition. In addition, the composition for a sizing agent had an NCO / OH of 1.1 (NCO / OH=1.1 / 1.0).

[0088] Evaluation method: In the examples and comparative examples, various evaluations were performed by the following tests.

[0089] Available time: In order to evaluate the coating operability of the sizing agent composition, the time (available time) when the viscosity of the sizing agent composition reaches a predetermined viscosity is measured. That is, the usable time (min) is the time when the viscosity of the above-mentioned mixed liquid A is used as the reference viscosity and the viscosity reaches 3 times the reference viscosity after the preparation of the si...

Embodiment 2～4

[0095] Examples 2 to 4, Comparative Examples 1 to 4:

[0096] Except that the formulation shown in Table 1 was used, the sizing agent compositions of Examples 2 to 4 and Comparative Examples 1 to 4 were prepared in the same manner as in Example 1 above, and various evaluations were performed. The evaluation results are shown in Table 1.

[0097] Example

Embodiment 5

[0099]Production of artificial turf: As an example of a fiber product with a sizing agent layer or artificial turf, the artificial turf is produced as follows. The pile made of polyethylene is implanted on the woven fabric (base cloth) made of polypropylene. Then, the sizing agent composition of Example 1 was made into a coating liquid, and the coating liquid was adjusted to 1200G / m using a coater (Applicator). 2 Coated on the back of the woven fabric, cured in a hot-air circulating oven at 110°C for 15 minutes, and maintained at 23°C and 65% for 5 days to obtain an artificial turf with a sizing agent layer thickness of approximately 0.75mm.

[0100] Spinning power: In order to evaluate the holding power of the sizing agent layer to the wool yarn, one of the plurality of wool yarns of the artificial turf was pulled out in accordance with JIS L1023, and the force required for the wire drawing (threading force) was measured. As for the evaluation criteria, when the drawing force was...

Abstract

The present invention relates to a composition for sizing agent, which can form sizing agent layer having equal degree physical properties with the existing one, its available time is long, and it can solidify in short time. The mentioned composition contains: multi-isocyanate which molecular containing more than two isocyanate-group, diol which molecular containing two hydroxylics, polyol which contains structural unit (i) from polyol containing more than three hydroxylics and number average molecular weight is 2000 ~ 10000, and activator containing bicyclo type amidine structure.

Description

Technical field [0001] The invention relates to a composition for a sizing agent and artificial turf. In more detail, it relates to a sizing agent composition and artificial turf that can form a sizing agent layer having the same physical properties as the previous sizing agent layer, can be used for a long enough time and have a short curing time. Background technique [0002] Conventionally, on the back of fiber products such as carpets and artificial turf, a pile glue layer for holding the fiber products and artificial turf has been arranged. The sizing agent layer, for example, can be woven (implanted) on the base fabric and then coated on the back of the base fabric with a composition for forming the sizing agent layer (hereinafter referred to as "sizing agent "Composition") is obtained by curing the applied sizing agent composition. [0003] However, from the viewpoint of coating workability, the above-mentioned sizing agent composition is required to not undergo a curing r...
