Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a ferret velvet-like fabric and a preparation method thereof. Background Art

[0002] In recent years, as people's environmental awareness has increased, wild animal fur products have become increasingly precious, and product production is limited and expensive, which has prompted the development of the artificial fur industry.

[0003] Imitation mink velvet fabric is a fabric made of artificial synthetic fiber that imitates the texture and appearance of mink fur. It is soft and smooth to the touch, warm and durable, easy to care for, and environmentally friendly. The finished product is exquisite and luxurious. It has a large application market in clothing manufacturing, home decoration, toy manufacturing and other fields, and is deeply favored by consumers.

[0004] The imitation mink fleece fabric can be divided into sheared fleece and plucked fleece. Both types of mink fleece are plucked, that is, the long hair of the mink fleece is plucked, leaving only the bottom fleece to improve the softness and smoothness of the fabric. It can be seen that the softness is a major focus of the quality of imitation mink fleece fabric. At present, imitation mink fleece fabrics are all made of synthetic fibers, which are still inferior to real mink fleece products. Almost all the imitation mink fur fabric products on the market have problems such as insufficient simulation, poor smoothness, hair loss on the fur side, and serious floating hair on the reverse side. Summary of the invention

[0005] The invention aims to overcome the problems in the prior art of insufficient development of raw materials for mink-like fur fabrics, hair loss and floating hair in the products, poor smoothness and high production cost.

[0006] In order to achieve the above object, the first aspect of the present invention provides a method for preparing a mink velvet-like fabric, the method using five combs numbered GB1, GB2, GB3, GB4, GB5, and comprising the following steps:

[0007] (1) Material selection: GB1 and GB5 use 75D / 48F FDY semi-dull polyester as raw material, GB2 and GB4 use 75D / 144FDTY semi-dull polyester as raw material, GB3 uses 68D / 72F FDY super-dull polyester as raw material;

[0008] (2) Weaving: Weaving the raw material in step (1) using a double needle bed warp knitting machine equipped with five guide bars, namely GB1, GB2, GB3, GB4 and GB5, to obtain a blank fabric with a three-layer structure; wherein the speed of the double needle bed warp knitting machine is 350-2400 r / min, and the pile height of the blank fabric is 6 mm;

[0009] (3) Slitting: At a speed of 8-10 m / min, the blank fabric is slit in the middle by a slitting machine to obtain a blank fabric with single-sided plush;

[0010] (4) post-finishing: the blank is subjected to the following operations in sequence: high temperature shaping, pre-ironing, hot blowing, combing, and ironing to obtain a ferret-like fleece fabric;

[0011] Among them, during the weaving process, the yarn padding numbers of each combing bar are GB1: 0-1-1-5 / 5-4-4-0 / / , GB2: 1-0-0-0 / 0-1-1-1 / / , GB3: 0-1-0-1 / / , GB4: 1-1-1-0 / 0-0-0-1 / / , GB5: 4-0-0-1 / 1-5-5-4 / / .

[0012] The second aspect of the present invention provides a mink fleece-like fabric prepared by the method described in the first aspect.

[0013] Compared with the prior art, the method provided by the present invention has at least the following beneficial effects:

[0014] (1) The present invention innovates the main raw material of the imitation ferret velvet fabric, making the velvet surface softer, more delicate and smoother, more similar to real fur fabric, and the finished product is luxurious and exquisite;

[0015] (2) The present invention adjusts the weaving process to ensure that the base fabric is dense and of good quality; the process organization is designed so that the front side of the fabric does not shed and the back side does not have loose hair when the fabric is unloaded from the machine, thereby ensuring that the fur surface of the finished imitation mink fur fabric is fluffy, soft, flat, firm and of high quality;

[0016] (3) The present invention adds a high-temperature shaping step to ensure the quality of the product plush; adjusts the post-finishing process and customizes the processing equipment according to the product characteristics to ensure that the finished product plush has high simulation, softness, smoothness, fluffyness, fullness, flatness and fineness.
