Embodiment 1

[0016] (1) Aramid fibers, polyamide fibers and permanent flame-retardant polyester fibers are used as raw materials with a mass percentage of 45%: 25%: 35%; wherein, the specifications of each fiber raw material are: aramid fiber 3.2dtex , 45mm; polyamide fiber 5.5dtex, 50mm; permanent flame-retardant polyester fiber 2.8dtex, 30mm.

[0017] (2) Spinning: Spinning a blended yarn with a fineness of 8.5dtex and a length of 35mm through the processes of cleaning, carding, drawing, two-for-one twisting, roving and fine sand; among them,

[0018] The cleaning process adopts the method of adding oil and water, more loosening and less beating, and stepwise feeding of cotton. After cleaning, the moisture regain of the raw sliver is 6-8%, the oil content is 1-1.5%, and the length of the cotton lap after cleaning is 22m. Cotton lap weight is 350g / m;

[0019] The technological parameter of described carding is: raw sliver quantitative 15g / 5m, cylinder speed 230r / min, licker-in speed 400r...

Embodiment 2

[0027] The difference from Example 1 is that the mass percentages of aramid fiber, polyamide fiber and permanent flame-retardant polyester fiber are 50%:20%:30%.

Embodiment 3

[0029] The difference from Example 1 is that the mass percentages of aramid fiber, polyamide fiber and permanent flame-retardant polyester fiber are 40%:25%:35%.

[0030] The blended home textile fabric prepared by the above method has a thermal shrinkage rate of 1% and a limiting oxygen index of 30% after being treated at a high temperature of 180°C, and has permanent flame retardancy.

Abstract

The invention discloses a manufacturing method for flame-retardant home textile fabric. The manufacturing method comprises the following steps that (1) raw materials are prepared; (2) spinning is performed; (3) weaving is performed; (4) finished fabric is manufactured. According to the method, the heat shrinkage rate of the manufactured home textile fabric is only 1% after the home textile fabric is treated at the high temperature of 180 DEG C, the limit oxygen index of the home textile fabric is 30%, and therefore the home textile fabric has a permanent flame retardant property. The manufacturing method for the flame-retardant home textile fabric is easy and convenient to operate and easy to implement; through the reasonable proportion of aramid fiber to polyamide fiber to permanent flame retardant polyester fiber, the manufactured home textile fabric has the excellent permanent flame retardant property and meanwhile has the properties such as abrasion resistance, quick-drying, heat resistance, low shrinkage and environmental friendliness; accordingly, the home textile fabric is flame-retardant fabric excellent in comprehensive property and has broad application prospects in home textile products.

Description

technical field [0001] The invention relates to the field of home textile fabrics, in particular to a method for preparing flame-retardant home textile fabrics. Background technique [0002] With the progress of society and the improvement of living standards, people have put forward higher and higher requirements for home textile products. In addition to meeting basic needs such as fashion, beauty, and comfort, they must also have flame-retardant functions to improve the use of home textile products. safety. The flame retardant properties of existing home textile fabrics are usually achieved through post-finishing methods, that is, the treatment method of soaking fibers, yarns, and cloths with flame-retardant liquids to form a layer of flame-retardant protection on the surfaces of fibers, yarns, and cloths. The flame-retardant home textile products obtained by the above-mentioned post-finishing method have the following disadvantages: the hand feeling of the fabric is poor...
