Abstract
(EN)
Disclosed is a method for preparing a machine-made water-soluble polyvinyl alcohol nonwoven fabric shopping bag. The preparation method specifically involves: (1) preparing a sizing finishing agent, wherein the sizing finishing agent comprises the following raw material components, in parts by weight: 10-20 parts of polyvinyl alcohol; 3-8 parts of a polyol copolymer polyether; 1-3 parts of a polyacrylamide hydrolysate; 2-5 parts of a polyol; 1-3 parts of an inorganic filler; 1-3 parts of urea; 0.1-0.3 part of a wetting agent; 0.2-0.5 part of an imidazolidinyl urea; 0.1-0.3 part of a p-hydroxybenzoate; and 100 parts of water; and these components are mixed to prepare the sizing finishing agent; (2) applying the sizing finishing agent to padding finishing and coating finishing processes for a polyvinyl alcohol nonwoven fabric; and (3) subjecting the polyvinyl alcohol nonwoven fabric, which has been padded or coated and sized, to mechanized automatic hot-seal bagmaking to obtain the shopping bag. The shopping bag provided by the present invention has excellent heat sealability and mechanical properties and a good hand feeling. By means of the method, the processing efficiency is improved, and the production cost is reduced.

Le procédé de préparation comprend spécifiquement : (1) la préparation d'un agent de finition d'encollage, l'agent de finition d'encollage comprenant les composants de matière première suivantes, en parts massiques : 10 à 20 parts d'alcool polyvinylique ; 3 à 8 parts d'un polyéther de copolymère de polyol ; 1 à 3 parts d'un hydrolysat de polyacrylamide ; 2 à 5 parts d'un polyol ; 1 à 3 parts d'une charge inorganique ; 1 à 3 parts d'urée ; 0,1 à 0,3 part d'un agent mouillant ; 0,2 à 0,5 part d'une imidazolidinylurée ; 0,1 à 0,3 part d'un p-hydroxybenzoate ; et 100 parts d'eau ; et ces composants sont mélangés pour préparer l'agent de finition d'encollage ; (2) l'application de l'agent de finition d'encollage à des processus de finition de rembourrage et de finition de revêtement pour un tissu non tissé à base d'alcool polyvinylique ; et (3) la soumission du tissu non tissé à base d'alcool polyvinylique, qui a été rembourré ou revêtu et encollé, à un processus de formation de sac par scellement à chaud automatique mécanisé pour obtenir le sac à provisions. Le sac à provisions selon la présente invention présente d'excellentes propriétés de thermoscellement et mécaniques et une bonne sensation à la main. Au moyen du procédé, l'efficacité de traitement est améliorée et le coût de production est réduit.
