High-brightness hemp/sorona blended fabric and machining process thereof

Abstract

The invention belongs to the technical field of spinning dyeing and printing and in particular relates to a high-brightness hemp / sorona blended fabric and a machining process thereof. The machining process comprises the following steps: singeing hemp / sorona blended blank cloth, carrying out desizing and scouring, carrying out specific bleaching, carrying out terylene whitening, carrying out whitening washing, washing with water and air flow, carrying out super softening, and carrying out tentering, wherein a water washing machine with a rolling groove and a vapor tank is adopted for whiteningwashing; the rolling groove is a guide roller groove; the cloth is soaked and rolled once, is steamed for 50-60 seconds at 95-100 DEG C in the vapor tank, and is further washed with water in ten waterwashing tanks; the ninth water washing tank has a pH value of 3.0-3.5; the cloth is further washed with clean water of 50-52 DEG C and dried by using a drying cylinder of 120-122 DEG C; the surface of the cloth has a pH value of 6-6.5. The fabric provided by the invention has the characteristics of high whiteness and high soaping fastness, a hemp fiber is good in moisture absorption and air permeability, and the fabric has natural styles of coolness and comfort. The invention further provides a machining process of the fabric. The machining process has continuity, is capable of achieving continuous production of large-scale products and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a high-whiteness hemp / Sorona blended fabric and a processing technology thereof. Background technique [0002] Flax is the cortical fiber of plants. Its function is to approximate human skin, and it has natural properties such as protecting the human body and regulating temperature. Modern plant anatomy proves that flax fiber is a natural bundle of fibers, and this unique structure makes it incomparable to non-hemp fibers. Hemp fabrics are deeply loved by consumers for their breathability and coolness. But it also has defects such as rough hand feeling, non-smooth wearing, easy wrinkling, poor drapability, rigid fibers, and poor saturation force. [0003] Solona fiber is a new type of environmentally friendly fiber extracted from corn developed by DuPont. The hemp / Sorona blended fabric is a new functional fiber fabric that combines the characteri...

Problems solved by technology

[0004] At present, the bleaching method of hemp / Sorona blended fabrics on the market is only ordinary bleaching, and some low-affinity brighteners are generally used in the whitening process, which is completed by padding and drying. The whiteness of the fabrics processed in this way is low and the production efficiency is not high. , the whiteness of each batch varies greatly, which cannot reach the grade of high-end fabrics, and cannot meet the requirements of stable and uniform quality of high-end fabrics
