Problems solved by technology

[0002] Pure cotton woven fusible interlining generally needs chemical anti-shrinkage finishing to ensure dimensional stability. At present, the commonly used method is to use amide-formaldehyde finishing agent and adopt padding and baking process for anti-shrinkage finishing. The characteristic is that the fabric after finishing The shrinkage rate is small, but there is a high potential risk of free and hydrolyzed formaldehyde, and formaldehyde, as a harmful substance, has strict restrictions on its content in textiles
Although the use of formaldehyde-free chemical anti-shrinkage finishing agents such as polycarboxylic acid can achieve formaldehyde-free anti-shrinkage finishing, but generally the shrinkage rate is relatively large, and the loss of strength is large, and the cost is high, which cannot meet the requirements for the use of interlining fabrics.

Abstract

The invention discloses a production method of a methanal-free purified-cotton woven adhesive interlining. The production method comprises the steps of pretreatment and mechanical shrunk finish; in the step of pretreatment, a cold pad-batch pretreatment production process is adopted, dyeing is performed by adopting a cold pad-batch dyeing production process with reactive dyes, glyoxal is taken as an anti-wrinkling finishing agent, a low-temperature tide-state cross-linked production process is adopted, hot melt powder with high bonding strength is adopted for powder point coating, and the number of coatings is controlled, so that after a combined sample is baked, the stripping strength is not less than 15N; in the step of mechanical shrunk finish for fabric subjected to powder point coating, the preshrunk quantity is controlled so as to ensure that after finishing, dimensional changes after laundering, in warp and weft directions, of the adhesive interlining are not less than -0.8 percent. According to the production method, a cold pad-batch process is adopted to perform the pretreatment, the dyeing and the shrink resistant finish, energy-saving and environment-friendly effects are realized, and the produced purified-cotton woven adhesive interlining does not release methanal, is barely damaged by strong force and is small in the dimensional changes after laundering.
