Problems solved by technology

It has a broad-spectrum antibacterial and bactericidal effect, but there are problems such as uneven release of antibacterial peptides in the fabric. At the beginning, the antibacterial peptides in the fabric are released quickly and in large quantities, and then rapidly decrease, resulting in the rapid weakening of the bactericidal effect of the fabric.

preparation example Construction

[0039] This embodiment discloses a method for preparing a soybean peptide textile fabric. The soybean peptide composition is mixed and stirred evenly, and the composite material slice is coated and extruded to obtain a masterbatch, and the masterbatch is added to the polyester chip and melt-spun to obtain a short fabric. Fiber or POY silk, a layer of speed-controlling film is compounded on the surface of short fiber or POY silk, and soybean peptide textile fabric is obtained through spinning, weaving, pre-setting treatment, printing and dyeing, padding, drying and setting, including the following steps:

[0040] Step 1: Mix and stir the soybean peptide composition evenly, then wrap it with high-efficiency heat-absorbing composite material slices, and obtain master batches through extrusion, wherein the mass percentage ratio of the soybean peptide composition to the composite material is (25- 26%): (74-75%);

[0041] Step 2: Set the temperature of the melt spinning machine to t...

Abstract

The invention discloses a preparation method of a soybean peptide textile fabric, and relates to the field of textiles. A soybean peptide composition is uniformly mixed and stirred, composite material slices are used for coating and extrusion to obtain master batch, the master batch is added into polyester chips, melt spinning is performed to obtain short fiber or POY, a layer of speed control film is compounded on the surface of the short fiber or the POY, and spinning, weaving, setting pretreatment, printing and dyeing, padding, drying and setting are performed to obtain the soybean peptide textile fabric. The method has the beneficial effects that the soybean peptide composition is wrapped by a composite material to prepare the master batch, the master batch is added at an outlet of a melt extrusion mechanism, the composite material absorbs heat and releases CO2 in the process of transferring the heat from the outer side to the inner side of the master batch, the CO2 can continue to take away the heat, melt cooling is accelerated, and pores are formed in the short fiber or the POY, so that bioactive components in the soybean peptide composition can be greatly prevented from being inactivated at high temperature, and the soybean peptide textile fabric has the longer service life.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for preparing soybean peptide textile fabrics. Background technique [0002] In the past ten years, with the change of people's lifestyle and the continuous improvement of consumption level, people pay more and more attention to their health. When choosing clothes, they will not only consider their color and style, but also consider their comfort and health care. Sexuality, comfort and health are the new concepts and trends of today's clothing consumption. The comfort of clothing covers clothing heat and humidity comfort, contact comfort and visual comfort, and is a multidisciplinary and complex problem involving human physiology, psychology, clothing and its fabrics and other factors. However, in the prior art reports on clothing comfort and health care, people often pay more attention to adding various substances to clothing to give it corresponding functions, but the protecti...
