Production technology of full-cotton powder point hot melting adhesive interlining

Abstract

The invention discloses a production technology of a full-cotton powder point hot melting adhesive interlining. The production technology sequentially comprises the following steps of: A) singeing; B) primary alkali rolling; C) primary steaming; D) secondary alkali rolling; E) secondary steaming; F) acid pickling; G) mercerizing; H) back bleaching; I) cloth spreading and sewing; J) resin finishing; K) curing; L) powder point coating; and M) solidifying with rubber powder. In the production technology disclosed by the invention, multiple processes are combined, the evenness, smoothness and handfeel of the full-cotton powder point hot melting adhesive interlining are greatly improved, the product quality is enhanced, the liquid entrainment rate after padding is moderate, the whiteness can be moderate while cloth is not tendered, thus the product quality is further improved, the service life of the product is prolonged, the full-cotton powder point hot melting adhesive interlining can berapidly cleaned when being washed with water, the efficiency is improved, the alkali liquor residual volume can be lower, the product quality is improved, the handfeel of the finished product is good, the hardness degree of the finished product is moderate, and the peeling strength of the finished product is high.

Description

【Technical field】 [0001] The invention relates to an all-cotton powder-dot hot-melt adhesive interlining, in particular to an improvement in the production process of an all-cotton powder-dot hot-melt adhesive interlining. 【Background technique】 [0002] my country is a big country in clothing, and the current annual output of clothing is about 30 billion pieces. With the improvement of people's requirements for clothing, most clothing currently uses interlining, and 80%-90% of clothing in my country also uses fusible interlining. [0003] At present, the processing technology of all-cotton powder-dot hot-melt fusible interlining is still relatively primitive, not only the process steps are unreasonable, but also the process parameter settings in each step are very unreasonable, resulting in the flatness of all-cotton powder-dot hot-melt fusible interlining. , poor smoothness and feel, low peel strength, poor product quality, and low grade. 【Content of invention】 [0004...
