Problems solved by technology

However, this method has the following disadvantages: one, because the sizing material is coated on the surface of the fabric in a passive manner by coating, a stiff film layer will be formed on the surface of the fabric after the subsequent calendering step, The softness of the fabric is significantly reduced; secondly, due to the formula of the rubber compound and / or the problem of the raw material itself, the film layer combined on the surface of the fabric cannot reach the cold resistance that people expect, so that the fabric made of surface coating The use of down products in cold regions is restricted; third, the tear strength is poor

Embodiment 1

[0013] The processing method of the anti-drilling fleece fabric of the present invention comprises a post-finishing step, and the post-finishing step includes a water-splashing step, a calendering step and a drying step, specifically: leading the fabric obtained from the previous process to a container filled with a solution of functional additives The water splash tank is used to impregnate the fabric with the functional additive solution, and when the fabric runs out of the functional additive solution, the functional additive solution on the fabric is squeezed off by the nip roll arranged on the water splash tank, so as to avoid the functional additive solution from dripping . The aforementioned functional auxiliary solution is prepared from the following raw materials in parts by weight, 6 parts of water repellent, 1 part of bridging agent, 1 part of resin and 0.1 part of accelerator. The pH value of the functional auxiliary solution is 4.5 . Among them: the water repel...

Embodiment 2

[0016] Only the parts by weight of the raw materials constituting the functional auxiliary solution are changed to: 5.5 parts of water repellent, 1.2 parts of bridging agent, 1.2 parts of resin and 0.08 part of accelerator. The pH of the functional auxiliary solution is 5; The advancing speed of the liquid tank and the fabric after being squeezed is changed to 12m / min, the pressure of the calender roll is changed to 13MPa, the temperature of the calender roll is changed to 175°C, the number of calendering times is changed to five times, and the temperature of the oven is changed to 180°C, change the traveling speed of the fabric to 60m / min. All the other are the same as the description to embodiment 1.

Embodiment 3

[0018] Only change the water repellant to 6.5 parts, the bridging agent to 0.8 parts, the resin to 0.8 parts and the accelerator to 0.12 parts, the pH of the functional auxiliary solution is 4; the travel speed of the fabric is changed to 15m / Min, the pressure of the calender roll is changed to 13MPa, the temperature of the calender roll is changed to 180°C; the temperature of the oven is changed to 180°C, the number of calendering times is changed to three times, and the traveling speed of the fabric is changed to 65m / min. All the other are the same as the description of embodiment 1 .

Abstract

The invention discloses a processing method of down-proof fabric. The invention belongs to the technical field of textile fabric processing. The method comprises a post-finishing step. The post finishing step comprises a water repelling step, a calendaring step, and a drying step. During the water repelling step, the fabric is delivered through a repelling tank containing a solution of a functional auxiliary agent; during the calendaring step, the surface of the fabric delivered through the repelling tank and processed by using a rolling liquid is calendared; during the drying step, the calendared fabric is dried by baking, such that the down-proof fabric is obtained. The method is characterized in that: the functional auxiliary agent comprises raw materials of, by weight: 5.5-6.5 parts of a water repelling agent, 0.8-1.2 parts of a bridging agent, 0.8-1.2 parts of resin, 0.08-0.12 parts of a promoting medium; the pH value of the functional auxiliary agent is 4-5; the pressure and the temperature of a calendaring roller of a calendaring machine, and the moving speed of the fabric are controlled during the calendaring step; and the temperature of a baking oven, and the moving speed of the fabric are controlled during the drying step. With the method, the down-proof effect is good, and the soft effect, the cold-resistance and the tearing resistance of the fabric can be ensured.

Description

technical field [0001] The invention belongs to the technical field of textile fabric processing, and in particular relates to a processing method of an anti-drill fleece fabric. Background technique [0002] The fabrics suitable for down products such as down clothing and down bedding (duvets, down cushions, down pillows, etc.) are mainly made of natural fibers such as cotton fibers, wool fibers, hemp fibers and chemical fibers such as polyester fibers and acrylic fibers. As known in the industry, the fabric made of cotton fiber has the advantages of ideal moisture absorption, breathability, softness and warmth retention, but it is easy to wrinkle and shrink. And though the lining made of aforementioned chemical fibers has the characteristics of soft touch, its air permeability is not as good as that of cotton fabrics. Furthermore, as is well known in the industry, the textile fabric used for processing down products must have outstanding anti-drilling performance, so as t...
