Problems solved by technology

[0003] At present, there are many ways to improve the downhole problem, mainly the following three methods: (1) calendering the fabric to reduce the gaps between the yarns to achieve the purpose of anti-downhole, as disclosed in the patent document CN102433743A A method for processing anti-drilling fleece fabrics is carried out after splashing water on the fabrics and then calendered for 3 to 5 times. However, this method requires multiple calendering treatments, which will cause damage to the yarns and affect the durability of the fabrics; ( 2) Coating the fabric and filling the gaps between the yarns with resin. For example, patent document CN104473360A discloses a warm, breathable and anti-drilling fleece fabric. A layer of silicone resin is coated on the fabric, although endowed with The fabric has a certain air permeability, but because the resin layer is not microporous, it will still feel stuffy when worn, and the lack of air permeability will cause the down to leak from the pinhole when the fabric is stressed; (3) combine the breathable membrane with the The fabric is compounded, and the film layer is used to block the gaps between the yarns. As disclosed in the patent CN106042496A, an environmentally friendly breathable anti-drilling fleece fabric is used. Breathability still needs to be further improved

preparation example Construction

[0012] The preparation method of the anti-pinhole fleece fabric of the present invention comprises the following steps:

[0013] (1) Preparation of coating resin processing fluid:

[0014] Acrylic resin 50-90 parts by weight

[0015] Silicone resin 10-50 parts by weight

[0016] Foaming agent 1 to 5 parts by weight

[0017] Foam stabilizer 2-8 parts by weight

[0018] 1-6 parts by weight of crosslinking agent.

[0019] Among them, the cross-linking agent is to increase the cross-linking degree of the resin and improve the mechanical properties of the resin. It is preferred to use isocyanate or melamine cross-linking agent; Salts of alkyl chains; foam stabilizers are used to control the bubble stability of the resin, preferably fatty acid salts.

[0020] (2) Next, foam the above-mentioned mixed resin processing fluid; wherein the speed of the constant speed mixer used for foaming processing is 500-3000r / min, and the time is 10-40min.

[0021] (3) Coating the down jacket f...

Embodiment 1

[0045] (1) Preparation of coating resin processing fluid:

[0046] Acrylic resin 70 parts by weight

[0047] Silicone resin 30 parts by weight

[0048] Cross-linking agent 5 parts by weight

[0049] Foaming agent 2 parts by weight

[0050] Foam stabilizer 6 parts by weight

[0051] The above components are firstly mixed, and then the mixed solution is subjected to foaming and stirring treatment, so that the foaming density reaches 140 g / L, and the coating resin processing fluid is obtained.

[0052] (2) Next, on the coating machine, apply the above-mentioned coating resin processing fluid at a grammage of 34g / m 220D nylon woven fabric, and then dried in a continuous drying oven (60°C → 130°C) to form a film, with a coating weight of 7.0g / m 2 Obtain product, its performance is shown in Table 1.

Embodiment 2

[0054] The amount of acrylic resin used is 60 parts by weight; the amount of silicone resin is 40 parts by weight, and the rest are the same as in Example 1 to obtain the anti-drilling fleece fabric, and its properties are shown in Table 1.

Abstract

The invention discloses a down feather leakage resistance fabric. The fabric includes a base fabric layer and a porous resin layer, and the porous resin layer contains acrylic resin and silicone resin. The fabric not only has good gas permeability, but also has good down feather leakage resistance property, and solves the problem of down feather leakage at a pinhole, and the fabric also has performance of a soft hand feeling and the like.

Description

technical field [0001] The invention belongs to the field of down jackets, and in particular relates to a method of coating fabrics with a foaming resin to solve the problem of down jacket leakage at the pinholes of the down jacket fabrics. Background technique [0002] As the most conventional cold-proof and warm-keeping product on the market, down jacket has a huge share and an irreplaceable role in the market. The biggest problem in down jackets is down drilling, so the development of anti-drilling down fabrics has always been a research direction for manufacturers. [0003] At present, there are many ways to improve the downhole problem, mainly the following three methods: (1) calendering the fabric to reduce the gaps between the yarns to achieve the purpose of anti-downhole, as disclosed in the patent document CN102433743A A method for processing anti-drilling fleece fabrics is carried out after splashing water on the fabrics and then calendered for 3 to 5 times.
