One of the reasons I think this style fell into disuse was because the 1960s cultural revolution disqualified the vocations of the nuns who dedicated hours of their time laundering and ironing these items. Actually, in some ways this question brings to mind a quote of St. Alphonsus, that may give some perspective for those who labor and spend hours to make the liturgy other-worldy and as beautiful as possible. Such labors are not in vain and are only understood in light of pursuing the divine will.
"It would be the greatest delight of the seraphs to pile up sand on the seashore or to pull weeds in a garden for all eternity, if they found out such was God's will. Our Lord himself teaches us to ask to do the will of God on earth as the saints do it in Heaven: 'Thy will be done on earth as it is in heaven.' (Matt. 6:10)."
