Description

Technical Field

[0001] The invention relates to the technical field of garment processing, in particular to a woven fabric material and fabric capable of replacing down. Background Art

[0002] As people's respect for animal rights and awareness of animal protection increase, the price of down is subject to market fluctuations, resulting in a corresponding increase in product costs. Down products are not washable and require high standards, such as sterilization and cleaning. After long-term use, the decomposition of down protein fibers will produce odor.

[0003] Existing filling cotton and other materials that replace down have problems such as poor warmth retention and durability, easy to clump after washing, and not water-repellent. Currently, it can only be used in the low-end market, while the high-end market is still mainly down, and the high-end sports market is currently blank.

[0004] The invention patent with publication number CN115710769A discloses an elastic imitation cotton fabric and its preparation process. The elastic imitation cotton fabric is composited by yarn A and yarn B. The yarn A is a POY chemical fiber or a fully stretched silk chemical fiber with a special-shaped section, and the yarn B is an elastic bicomponent long fiber. The present invention uses yarn C composited by yarn A with a low shrinkage special-shaped section and yarn B with an elastic bicomponent, and uses yarn C to weave fabric. During dyeing, the shrinkage difference between yarn A and yarn B forms a rich cotton feeling on the surface of the fabric. The fabric can be industrially produced, has excellent elasticity, quick-drying functionality, and good cotton feel. The fabric has a cotton feel and elasticity, but its thermal insulation performance is insufficient and it cannot replace down.

[0005] Therefore, a woven fabric material with good thermal insulation performance that can replace natural feathers is needed. Summary of the invention

[0006] In order to solve the problems in the prior art, the present invention provides a woven fabric material that can replace down. The woven fabric material that can replace down can be industrially produced and has the warmth retention property of natural feathers.

[0007] The technical solution of the present invention is as follows:

[0008] A woven fabric material that can replace down, the yarn used is a combination of elastic fibers and special-section fibers interwoven with each other.

[0009] Preferably, in the above scheme, the linear density of the yarn is 30-300 deniers, and the linear density of the monofilament is 0.1-4 deniers.

[0010] Preferably, in any of the above schemes, the special-shaped cross-section fiber is any one of the cross-sections with a higher degree of special shape, such as hollow, cross, octagonal, gear hollow, etc.

[0011] Preferably, in any of the above schemes, the gloss of the yarn is any combination of glossy, semi-gloss and matte.

[0012] A woven fabric that can replace down, the fabric is made of the above-mentioned yarn using a shuttle loom to weave the grey cloth, the spacing between the interwoven part and the non-interwoven part of the fabric structure is 0-15cm. The special fiber structure of the special-shaped cross-section fiber can contain a large amount of static air, which can bring a comfortable warming effect to the fabric.

[0013] Weaving and dyeing process of the above-mentioned fabric that can replace down:

[0014] The processing is carried out through the process of weaving grey cloth → desizing (80-100 degrees * 8min) → conditioning (60-130 degrees * 30min) → pre-setting (150-180 degrees) → dyeing (80-135 degrees) → shaping (130-180 degrees).

[0015] The present invention provides a woven material with heat preservation that can replace down. As a new material to replace down, it can be processed using 100% recycled materials, making an outstanding contribution to the environment. It has the lightness, warmth retention and fluffiness of natural feathers, is easy to dry, and has unlimited design sense. It can be dyed and can also be easily washed in a household washing machine. It takes sustainable development into consideration while also having functionality. Even if it is compressed, its functionality will not be destroyed, and it is easy to store and organize.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Machine washable

[0018] It can be easily cleaned in a household washing machine, does not clump easily and dries easily.

[0019] 2. Environmental protection

[0020] No animals are slaughtered to obtain the raw materials, and recycled and sustainable raw materials can be used for processing.

[0021] 3. Dyeable

[0022] Artificial down can be dyed in a variety of colors to meet customer preferences.

[0023] 4. No odor

[0024] Poultry down needs to be sterilized at high temperatures to remove odors before use. Some processing plants do not process thoroughly, which can cause down to have odors. Artificial down does not produce odors. BRIEF DESCRIPTION OF THE DRAWINGS
