Abstract
Description
Technical Field
The invention relates to the technical field of textiles, in particular to a special fabric with flame-retardant and antibacterial functions, and a preparation method and application thereof.
Background
The training wear, the comprehensive protective wear, the anti-load wear and the anti-soaking wear are produced by using special fabrics. The special fabric comprises a flame-retardant fabric, an oil-proof fabric, a waterproof fabric, an antistatic fabric, an acid-base resistant fabric, an ultraviolet-proof fabric, a wear-resistant fabric, a thermal fabric and other fabrics with special functions.
At present, the existing flame-retardant fabric is generally woven by blending meta-aromatic polyamide fibers and para-aramid fibers or stainless steel fibers and the like, but has harder hand feeling and is not suitable for producing clothes.
Disclosure of Invention
The first aim of the invention is to provide a preparation method of special fabric with flame-retardant and antibacterial functions, which can prepare special fabric meeting the comfort of applicable production clothing, and has better flame-retardant and antibacterial performances.
The second aim of the invention is to provide a special fabric with flame-retardant and antibacterial functions, which has better flame-retardant and antibacterial performances on the basis of meeting the comfort applicable to the production of clothes.
The third object of the invention is to provide an application of special fabric with flame-retardant and antibacterial functions, which can be used for producing training clothes, comprehensive protective clothing, and anti-load clothes and anti-soaking clothes.
The embodiment of the invention is realized by the following technical scheme:
a preparation method of special fabric with flame-retardant and antibacterial functions comprises the following steps:
s1: blending cotton fibers and the compound fibers to obtain blended yarns, and weaving the blended yarns into blended fabrics;
s2: dyeing the blended fabric by using dye to obtain dyed blended fabric;
s3: firstly padding the dyed blended fabric with an antibacterial agent, and then padding the dyed blended fabric with a first flame retardant after drying to obtain a flame-retardant blended fabric;
s4: and (3) finishing the second flame retardant on the flame-retardant blended fabric by layer-by-layer self-assembly to prepare the special fabric.
Further, the compound fiber in the step S1 includes one or more of vinylon fiber, polypropylene fiber and chloridion fiber.
Further, in the step S1, the cotton fibers and the compound fibers are drawn according to the weight ratio of (1-3), the blended yarn is prepared through the procedures of roving, spinning and double twisting, and then the blended yarn is woven into the blended fabric through tatting.
Further, the antibacterial agent in the step S3 comprises the following components in parts by weight: 10-15 parts of water-soluble chitin, 15-22 parts of guanidine nitrate and 70-80 parts of water.
Further, the first flame retardant in the step S3 includes the following components in parts by weight: 30-45 parts of sodium pyrophosphate, 10-15 parts of zinc oxide and 80-90 parts of 70-80% acetic acid aqueous solution.
Further, the specific processing method in step S3 is as follows: adding (20-30) dyed blended fabric into an antibacterial agent or a first flame retardant according to a bath ratio of 1, oscillating for 20-35 min at 45-50 ℃, and performing one-dip one-roll, wherein the liquid rolling rate is 65-75%; drying at 80-85 ℃ for 5-8 min, and baking to obtain the flame-retardant blended fabric; padding the dyed blended fabric with an antibacterial agent and a first flame retardant for 1-5 times.
Further, the second flame retardant in the step S4 comprises 8-15 wt% of chitosan and 6-12 wt% of sodium hexametaphosphate.
Further, the specific processing method in step S4 is as follows: adding the flame-retardant blended fabric into 8-15 wt% chitosan solution according to a bath ratio of 1 (10-15), dipping for 20-30 min, taking out, washing for 2-3 times by water, drying, adding into 6-12 wt% sodium hexametaphosphate solution according to a bath ratio of 1 (10-12), dipping for 8-12 min, taking out, washing for 2-3 times by water, and drying; repeating the above treatment for 5-10 times to obtain the special fabric.
A special fabric with flame-retardant and antibacterial functions is prepared by a preparation method of the special fabric with flame-retardant and antibacterial functions.
The special fabric with the flame-retardant and antibacterial functions is used for producing training clothes, comprehensive protective clothing, and anti-load clothes and anti-soaking clothes.
The technical scheme of the embodiment of the invention has at least the following advantages and beneficial effects:
1. the invention selects cotton fiber, vinylon fiber, polypropylene fiber or vinylon fiber for blending weaving, so that the fabric has certain flame retardance and high comfort, and is suitable for producing clothes.
2. According to the invention, the first flame retardant is padded in advance, and then the second flame retardant is self-assembled and finished on the fabric layer by layer, so that the fabric has better flame retardance; meanwhile, the fabric is padded with the antibacterial agent, so that the fabric has better antibacterial property.
