Problems solved by technology

The liquid removal technology mainly uses rollers, vacuum, air jet and other methods to make the fabric with a small amount of water. It is a relatively commonly used low liquid supply technology, but there is a certain limit to the reduction of the fabric liquid rate. In addition, the treatment effect is limited. Inhomogeneity also limits its application

preparation example Construction

[0014] A method for preparing non-ironing textiles, the specific steps of the preparation method are as follows:

[0015] a Prepare the atomized finishing solution, prepare the finishing agent and the catalyst at a mass ratio of 2.5:1 to make the atomized finishing solution, wherein the finishing agent is one of 2D resin or glyoxal, and the catalyst is magnesium chloride or aluminum sulfate One of them, atomized finishing liquid refers to one of 50-100g / L2D resin and 20-40g / L magnesium chloride or 50-100g / L glyoxal and 20-40g / L aluminum sulfate, according to the composition of the fabric According to different fiber materials, different non-ironing finishing systems are selected. For cellulose fiber fabrics such as cotton and hemp, 2D resin can be used as a non-ironing finishing agent. Under the catalysis of magnesium chloride, the finishing agent and fibers undergo a cross-linking reaction. , for non-ironing finishing. For protein fiber fabrics such as wool and silk, glyoxal ...

Embodiment 1

[0022] According to the above process steps: select cotton fabrics as the textiles to be finished, the finishing agent and the catalyst are formulated into an atomized finishing liquid in a mass ratio of 2.5: 1, and the atomized finishing liquid contains 50g / L2D resin and 20g / L magnesium chloride . The atomized finishing liquid is atomized by a high-frequency ultrasonic atomizer to form atomized microbeads with a particle size of 5 μm, which are evenly sprayed on one side of the cotton fabric running at a speed of 1m / min through the nozzle of the ultrasonic atomizer, and ultrasonically The distance between the nozzle of the atomizer and the surface of the running cotton fabric is 5mm, and the cotton fabric after single-sided gradient atomization is baked at 180°C for 1 minute, and then the baked cotton fabric is soaped, washed, After drying, the non-ironing cotton textile finished product is obtained by ultrasonic single-sided gradient atomization finishing.

Abstract

The invention belongs to the technical field of textile processing, and in particular relates to a method for preparing non-ironing textiles. The prepared non-ironing finishing liquid forms uniform and fine finishing liquid atomized beads through high-frequency ultrasonic atomization, which are directly sprayed onto the running fabric. By adjusting the running speed of the fabric at the high-frequency ultrasonic atomizing nozzle and ultrasonic The distance between the nozzle of the atomizer and the surface of the running fabric is used to control the amount of atomized finishing liquid sprayed on the fabric, thereby controlling the distribution and state of the atomized concentration gradient of the finishing liquid on the textile, and then after subsequent baking and post-treatment The process forms ultrasonic single-sided gradient atomization to finish non-ironing textiles. At this time, only one side of the textile has undergone ultrasonic atomization and non-ironing finishing, so that the textile can obtain non-ironing performance, and the side that is in direct contact with the skin during wearing has not been subjected to ultrasonic atomization and non-ironing finishing, and remains the original fiber composition, maintaining natural fibers Various excellent properties unique to it improve the wearability of the finished fabric.

Description

technical field [0001] The invention relates to a method for preparing non-ironing textiles, belonging to the technical field of textile processing. Background technique [0002] Cotton, wool, silk, hemp and other natural fibers commonly used in textiles are a kind of textile raw materials with excellent performance, but the textiles made of these natural fibers generally have problems such as easy wrinkling and poor non-ironing performance during wearing and washing. Subsequent non-ironing finishing is required to improve its wearing performance. Conventional non-ironing finishing is to dip the entire fabric into the finishing solution for pad-baking treatment. The technical route is simple, but at this time the fabric absorbs a large amount of finishing agent, so that both sides of the fabric can obtain the same non-ironing effect. At the same time, when the fabric with this conventional double-sided non-ironing treatment is worn, the side that is in direct contact with t...
