Abstract
The invention relates to the technical field of functional fabrics, and discloses an antibacterial, hygroscopic and exothermic amino acid fabric, a preparation method thereof and application thereof in underwear. The preparation method of the antibacterial, hygroscopic and exothermic amino acid fabric comprises the following steps: taking hyaluronic acid, glutamic acid, serine and proline as raw materials, and obtaining amino acid fibers rich in amino acids through electrostatic spinning; blending amino acid fibers, modified acrylic fibers and modal fibers into yarns, and weaving the yarns and spandex into fabric; pretreating the fabric by using sodium carbonate and a scouring agent; dyeing the pretreated fabric; the dyed fabric is subjected to antibacterial softening finishing by an antibacterial softening finishing agent; and raising and shaping the antibacterial soft-finishing fabric to obtain the antibacterial, moisture-absorbing and heating amino acid fabric. The antibacterial, moisture-absorbing and heating amino acid fabric provided by the invention can play a good role in caring skin, is comfortable and soft, has good antibacterial, moisture-absorbing and heating effects, and can be used for manufacturing underwear.
Description
Technical Field
The invention relates to the technical field of functional fabrics, in particular to an antibacterial, moisture-absorbing and heating amino acid fabric, a preparation method thereof and application thereof in underwear.
Background
Along with the rapid development of society and the continuous improvement of the technological level, the requirements of people on the textile taking are changed from the most basic clothing energy shielding body to multifunctional textiles with beautiful and comfortable appearance, antibacterial and antifouling properties, warm in winter and cool in summer, and the like. In recent years, considering that the traditional winter clothing is effective in maintaining the warm keeping performance, is often too bulky and thick and is not attractive, meanwhile, the traditional warm keeping fabric is often poor in hygroscopicity and air permeability, sweat is difficult to effectively discharge in winter activities, discomfort caused by damp and gradual cooling is generated, bacteria are easy to breed, and therefore, how to realize the moisture absorption and heat generation property and the antibacterial property of the fabric becomes a worthy technical problem.
Disclosure of Invention
In order to solve the technical problems, the invention provides a preparation method of an antibacterial, hygroscopic and exothermic amino acid fabric, which comprises the following steps:
Step (1) taking hyaluronic acid, glutamic acid, serine and proline as raw materials, and obtaining amino acid fibers rich in amino acid through electrostatic spinning;
Step (2) blending amino acid fibers, modified acrylic fibers and modal fibers into yarns, and weaving the yarns and spandex into fabric;
the fabric obtained in the step (3) and the step (2) is pretreated by soda ash and scouring agent;
step (4) sequentially carrying out dyeing treatment of acrylic fiber dyeing and cotton dyeing on the pretreated fabric;
The fabric dyed in the step (5) is subjected to antibacterial softening finishing by an antibacterial softening finishing agent;
the preparation method of the antibacterial softening finishing agent comprises the following steps:
step B1, obtaining a composite antibacterial agent through esterification reaction of rosmarinic acid and citral;
step B2, modifying the composite antibacterial agent through 3-aminopropyl triethoxysilane to obtain an amino modified composite antibacterial agent;
step B3, reacting DL-lipoic acid with an amino modified composite antibacterial agent to obtain an antibacterial additive;
