SYNTHETIC LEATHER
Provided is a synthetic leather including: a base fabric that has a limiting oxygen index of 25 or more, and that is a knitted body of a yarn including a flame-retardant fiber having a limiting oxygen index of 25 or more, a cellulose-based fiber, and a carbon fiber; an adhesion layer containing a flame retardant, the adhesion layer being provided at at least one side of the base fabric; and a skin layer provided at a side of the adhesion layer opposite from a side at which the base fabric is provided.
SELF-HEALING RESIN COMPOSITION AND ARTIFICIAL LEATHER MANUFACTURED THEREFROM
A self-healing resin composition includes 35 phr to 110 phr of a main resin, 10 phr to 30 phr of a self-healing component, a hardener, a matting agent, and a solvent. The main resin contains a diol monomer and a diisocyanate monomer. The self-healing component includes at least one of a cyclosiloxane and a self-healing component as represented in a formula (I) of:
##STR00001##
R.sup.1 is formed from a first isocyanate, R.sup.2 is formed from a second isocyanate, and R.sup.3 is selected from the group consisting of:
##STR00002##
x is an integer ranging from 3 to 50. y is an integer ranging from 3 to 50. m is an integer ranging from 3 to 50. n1 is an integer ranging from 3 to 50. n2 is an integer ranging from 3 to 50.
ARTIFICIAL TURF
Provided is an artificial turf, including a base cloth, artificial turf yarns tufted on the base cloth, and a bonding layer applied on the base cloth. The bonding layer is provided with water permeable holes formed by blowing air onto the base cloth through an air blowing device. The artificial turf has excellent water permeability. Moreover, there is no need to pierce an adhesive side of the base cloth during production, thereby avoiding damage to the structure of the artificial turf by piercing. This effectively prevents the artificial turf yarns from loosening and falling off and prolongs the service life of the artificial turf.
