Production method of nonwoven fabrics and artificial leather base substance for artificial leather

摘要

SummaryTopic fiber web size and the textile goods granting the formal stability which is sufficient for the artificial leather base substance which is obtained by producing the nonwoven fabrics for the artificial leather without giving the big damage to the textile goods, it is possible, production method of the nonwoven fabrics and the artificial leather base substance for the artificial leather is offered.Repeating solution expedient fiber web size and the textile goods, in the production method of the nonwoven fabrics for the artificial leather which it makes unify with needle punch processing slip, forms the said textile goods mainly diameter of the warp which when the bave which S₁, designates the diameter of the weft as S_2, penetrates the said textile goods the said warp and as D_{2 the} angle which is formed D₁, the said weft and the angle which is formed designating, production method of the nonwoven fabrics for the artificial leather which feature that total bave depth (P) of the said bave satisfies the below-mentioned formula.S₁ 2PS1/cos (D₁ (/180))... (1)S₂ 2PS2/cos (D₂ (/180))... (2)
