[0068] In some embodiments, the fabric layer 100 includes one or more textiles of polyester, nylon, or cotton.

[0069] In some embodiments, the fabric layer 100 comprises one or more of polyester, nylon, nylon, and cotton. It is readily apparent that the fabric layer 100 may also be made of other materials. For example, the fabric layer 100 may comprise pongee, nylon, or taslon. As outdoor clothing, it should be wear-resistant and have a certain degree of wind resistance. Therefore, the fabric layer 100 is selected from a dense, durable, and wear-resistant woven fabric.

[0070] In some embodiments, the thickness of the fabric layer 100 is 0.1 mm to 0.4 mm, and the weight of the fabric layer 100 is 80 g / m 2 ~150g / m 2 .

The production process of the fleece includes passing the fabric through a machine to form fine fluff on one or both sides of the fabric, thereby producing an effect similar to wool but more lightweight and easy to care. The fleece is widely used in casual clothing, sports equipment, coats, blankets, and home furnishings due to its comfortable hand feeling and good thermal performance. The thermal lining 300 of this application adopts the fleece, which can achieve that the windproof and breathable eco-friendly fabric 10 has warmth, lightness, and durability, and is easy to care.

[0076] In some embodiments, the thermal lining 300 has a CLO value greater than 0.9, which is measured according to GB / T 35762.

The material of the thermal lining 300 includes polyester / polyamide / cotton and their blended fabrics, such as but not limited to fleece / brushed fabric / knit cotton, etc., to achieve good warmth of the windproof and breathable eco-friendly fabric 10.

[0080] In some embodiments, the first glue point is applied to the fabric layer 100 using a rotary screen printing roller coating method. The polyolefin microporous layer 200 is then covered on the first glue point of the fabric layer 100. After lamination, the first glue point is allowed to cure at room temperature of 20°C to 30°C for at least 48 hours. Preferably, the material of the first glue point can be a moisture-curing polyurethane hot melt adhesive.

[0081] In some embodiments, the second adhesive dot is applied to the polyolefin microporous layer 200 using a rotary screen roller coating method. The thermal lining 300 is then placed over the second adhesive dot on the fabric layer 100. After lamination, the second adhesive dot is cured at room temperature of 20°C to 30°C for at least 48 hours. Preferably, the second adhesive dot can be made of a moisture-curing polyurethane hot melt adhesive.

The fabric layer 100 is treated using a dip-and-pad process, with the liquid content controlled at 10% to 25%. The fabric layer 100 is then dried at 100°C to 120°C for 10 to 30 minutes. The water-repellent finish adheres to the fabric layer 100, forming a water-repellent finish layer.

[0093] S3, use a rotary screen printing roller or a dot micro-concave roller to apply a single-component polyurethane hot melt adhesive to one surface of the fabric layer 100, and apply the hot melt adhesive to the fabric layer 100 in a dot-shaped manner to form a plurality of first adhesive dots.

[0094] S4. After lamination, place the single-component polyurethane hot melt at room temperature and relative humidity greater than 40% for 2 to 7 days to fully cure.

[0095] S5. Use a rotary screen printing roller or a dot-shaped micro-concave roller to apply a single-component polyurethane hot melt adhesive to one surface of the thermal insulation lining 300. The single-component polyurethane hot melt adhesive is applied to the thermal insulation lining 300 in a dot-shaped manner to form a plurality of second adhesive dots.

[0097] In some embodiments, the water-repellent finishing agent includes a fluorine-containing water-repellent finishing agent or a fluorine-free water-repellent finishing agent.

[0098] In some embodiments, the fluorine-free waterproof finishing agent includes one or more of silicones, fluorine-free water-based polyurethanes, polyacrylates and amino-modified polyurethanes, aluminum soaps, paraffins / metal salts, pyridinium quaternary ammonium salts, long-chain fatty amide compounds, fatty hydrocarbon melamine derivatives, and fatty acid metal complexes. Fluorine-free waterproof finishing agent is a chemical used in the textile finishing process, which can help fabrics obtain functions such as waterproofing, oil resistance and stain resistance, while avoiding the use of traditional fluorinated compounds to reduce the impact on the environment. Fluorine-free waterproof finishing agent does not contain fluoride and is therefore considered to be more environmentally friendly. For example, fluorine-free waterproof finishing agent includes HOLPOSON® ECO-0C, which is a fluorine-free single anti-finishing agent produced by Zhejiang Fulpusheng New Materials Co., Ltd., or fluorine-free waterproof finishing agent includes ZJ-XR88 washable fluorine-free waterproof agent.

[0099] In some embodiments, the fluorine-containing waterproof finishing agent includes one or more of polytetrafluoroethylene, fluorine-containing alkyl acrylate copolymers, perfluorocarboxylate chromium complexes, organic fluorine resins, and fluorine-containing (meth)acrylates. Fluorine-containing triple-proofing finishing agents refer to chemicals containing fluoride used in the post-processing process of textiles. They can give fabrics the functions of waterproofing, oil resistance, and stain resistance, referred to as "three-proofing". This type of finishing agent has been widely used in the textile industry due to its excellent durability and high efficiency, especially in the fields of outdoor clothing, sports equipment, and functional textiles. The main active ingredient of the fluorine-containing triple-proofing finishing agent is usually a long-chain perfluoroalkyl or polyfluoroalkyl compound (such as C6 or C8 fluorocarbon chain).

[0100] In some embodiments, the crosslinking agent can be a polyisocyanate, such as hexamethylene diisocyanate (HDI).
