Embodiment

[0041] Spin and produce 12tex+36D flame-retardant blended yarn on the QFA1528 spinning machine equipped with a core-spun yarn device and modified by a full-spinning system. The flame-retardant blended yarn is blended by weight percentage of the following components: 25% Flame retardant acrylic fiber, 25% flame retardant polyester filament, 25% hemp fiber and 25% cotton fiber, the yarn has excellent antibacterial, mildew and flame retardant properties, comfortable hand feeling, good moisture absorption and breathability sex.

[0042] The manufacturing process is as follows:

[0043] The first step is to process hemp through fiber pretreatment, first opening and cleaning, and first carding to obtain raw hemp slivers, and to obtain raw cotton slivers through the first cleaning and carding of cotton, and then to obtain raw hemp slivers and raw cotton slivers Shred into loose fiber state respectively, then the 25% hemp fiber and 25% cotton fiber obtained by shredding are mixed in ...

Abstract

The invention relates to a flame retardant blended yarn and a production method thereof. According to weight percentage, the flame retardant blended yarn is formed by the following components through blending: 25-30% of flame retardant polyester filament yarns, 20-25% of flame retardant acrylic fibers, 20-30% of hemp fibers and 20-30% of cotton fibers. The production method includes: making hemp fibers and cotton fibers into card slivers respectively and tearing the card slivers into loose fibers, and making the card slivers into hemp/cotton blended combed silvers through second blowing carding in a single fiber type mixing way; making the flame retardant acrylic fibers into flame retardant acrylic card silvers; producing blended rough yarns by use of the hemp/cotton blended combed silvers and the flame retardant acrylic card silvers; producing flame retardant blended yarns by use of spun yarns in a core spun mode; producing the needed flame retardant blended yarns after plasma preprocessing and yarn flame retardant finishing. According to the flame retardant blended yarn and the production method thereof, the hemp fibers, the cotton fibers and two flame retardant fibers are selected for blending, and accordingly the produced yarns have excellent flame retardant performance as well as good antibacterial, moisture absorptive and ventilate wearing performances; the spun yarns are in the core spun mode so the tare effect is eliminated and the flame retardance is improved.

Description

technical field [0001] The invention relates to the field of novel yarns, in particular to a flame-retardant blended yarn and a production method thereof. Background technique [0002] Flame-retardant acrylic fiber is made on the basis of traditional acrylic fiber through flame-retardant treatment. Ordinary acrylic fiber has many excellent properties, including soft hand feeling and good elasticity. It has the reputation of "synthetic wool", but it is sensitive to heat and has poor heat resistance. The acrylic fiber after flame retardant treatment maintains the excellent properties of the original acrylic fiber [0003] Physical and mechanical properties, and the limiting oxygen index reaches more than 27, which makes the fabric spun from flame-retardant acrylic fiber excellent in comfort and not easy to burn. Flame-retardant polyester fiber is similar to flame-retardant acrylic fiber. It is made of flame-retardant treatment on the basis of traditional synthetic fibers. Th...
