Description

Technical Field

[0001] The present invention relates to the technical field of down jackets, and in particular to a down-locking down jacket and a down-locking processing method thereof. Background Art

[0002] In recent years, down products have become an indispensable daily necessity in people's daily lives, and down jackets are essential clothing for people to keep warm in winter. Down jackets may have the problem of down drilling during production and use. In order to prevent the down from drilling out of the fabric and flying around, causing discomfort, manufacturers usually spray an antistatic layer on the inner wall of the filling port of the down filling during the production of down jackets to prevent the down in the filling port from drilling out of the down jacket due to static electricity. However, when spraying the antistatic agent on the inner wall of the filling port, in order to ensure the smooth progress of the spraying process, the filling port needs to be blown and inflated. As a result, the pores of the inflated down jacket fabric increase, resulting in the antistatic agent being easily splashed from the pores of the fabric when spraying it on the inner wall of the filling port, causing the antistatic agent to act on the outer surface of the down jacket fabric, affecting the softness of the fabric and resulting in a poor feel of the down jacket. In addition, the antistatic agent used to prevent down static electricity has a single function and cannot provide long-term anti-mildew protection for the down in the down jacket. Summary of the Invention

[0003] The main purpose of the present invention is to provide a down-locking down jacket and a down-locking processing method thereof, which can effectively solve the problems in the background technology.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A down-locking down jacket and a down-locking processing method thereof, comprising the following steps:

[0006] S1: Weaving: Using a weaving machine, nylon fiber filament, spandex elastic fiber and wool fiber are blended and then woven into a grey fabric to obtain an outer fabric and an inner fabric;

[0007] S2: napping: the reverse side of the outer fabric and the reverse side of the inner fabric in S1 are subjected to multiple napping treatments to form a velvety layer on the inner side of the outer fabric and the inner side of the inner fabric;

[0008] S3: Fabric sewing: Place the napped side of the outer fabric and the napped side of the inner fabric facing each other, and sew the outer fabric and the inner fabric together with needle and thread, so that a number of filling holes are formed between the outer fabric and the inner fabric, and needle holes are formed at the stitching of the needle and thread and the outer fabric and the inner fabric;

[0009] S4: Preparation of antistatic coating: The fan discharges air to inflate the inside of the filling port, and a sprayer is used to spray an antistatic agent on the inner surface of the outer fabric and the inner fabric that have been subjected to the napping treatment, so that an antistatic coating is formed inside the filling port of the outer fabric and the inner fabric;

[0010] S5: Filling: Use a filling machine to fill the down into the filling opening, sew the filling opening with needle and thread, and perform edge pressing on the sutured part of the filling opening to obtain a down jacket with locked down.

[0011] As a further optimization solution of the present invention, the warp and weft densities of the outer and inner fabrics in S1 are both 120×140-150×145 threads / cm.

[0012] As a further optimization solution of the present invention, the weight ratio of the nylon fiber filament, the spandex elastic fiber and the wool fiber in S1 is 2:1:1.

[0013] As a further optimization solution of the present invention, the roughening treatment method in S2 includes the following steps:

[0014] A1: Apply raising oil to the reverse side of the outer fabric and the reverse side of the inner fabric;

[0015] A2: Use a napping machine to nap the reverse side of the outer layer fabric and the reverse side of the inner layer fabric three times, with a cloth speed of 12m / min.

[0016] As a further optimization scheme of the present invention, the raw materials for preparing the antistatic agent in S4 include, by weight, 25-30 parts of butanol phosphate, 5-8 parts of stearic acid, 15-20 parts of propylene glycol, 10-14 parts of ethanol, 8-14 parts of dimethyl terephthalate, 12-16 parts of diethanolamine, 4-8 parts of polyurethane, 10-15 parts of fragrance, 10-15 parts of surfactant, and 220-340 parts of deionized water, which are mixed after heating and stirring in a stirrer for 20 minutes.

[0017] As a further optimization solution of the present invention, the stirring speed of the stirrer is 160 r / min, and the heating temperature is 150-160°C.

[0018] As a further optimized solution of the present invention, the surfactant is sodium fatty alcohol polyoxyethylene ether sulfate or ammonium fatty alcohol polyoxyethylene ether sulfate.

[0019] As a further optimized solution of the present invention, the aromatherapy agent comprises, by weight, 5-10 parts of hyacinth, 6-12 parts of patchouli, 5-10 parts of pine needles, 3-8 parts of mugwort, 6-12 parts of thyme, 3-6 parts of shan hemp stems and 3-6 parts of tamarind fermentation.

[0020] A down jacket with good down locking effect is produced by the down locking treatment method.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, before the fabric is sewn, the side of the fabric where the filling opening is formed is subjected to multiple napping treatments, so that the surface of the fabric that has been subjected to multiple napping treatments forms a velvety layer on the inner side of the outer fabric and the inner fabric, thereby increasing the fiber length of the fabric and preventing the down openings in the down jacket from drilling out from the pores. In addition, during the subsequent antistatic agent spraying process, the napped fabric effectively prevents the antistatic agent from splashing out from the pores of the bulging fabric while increasing the contact area between the antistatic agent and the fabric, thereby improving the antistatic effect and preventing the antistatic agent from acting on the fabric surface.

[0023] 2. In the present invention, by adding an aromatherapy agent to the antistatic agent and rationally mixing the tamarind fermentation product and other natural plant aromatherapy agents in the aromatherapy agent, the long-term antistatic effect of the fabric in a high-temperature washing environment is ensured, thereby making the down jacket more resistant to high-temperature washing.

The performance tests of these down jacket samples with good down-locking effects were carried out, including: (1) anti-down drilling performance test, using the rotating box method, the test samples were placed in a rotating box filled with hard rubber balls, and the rotating box rotated at a constant speed to bring the rubber balls to a certain height, impacting the test sample bags in the box, simulating the various squeezing, rubbing, collision and other effects that down products are subjected to during wearing. Finally, the anti-down drilling performance of the seamless grid anti-down fabric was evaluated based on the number of down drilling roots of the test samples; (2) softness test, the softness of the blended fabrics was tested separately, and the blended fabrics were subjectively rated by touch using a 5-person rating method. The lower the hand feel level, the worse the fabric feel, and the higher the hand feel level, the better the fabric feel; (3) odor test, the down jacket samples of each group with good down-locking effects were tested for odor according to GB 18401-2010 "National Basic Safety Technical Specifications for Textile Products". The odor is detected by olfactory method. If a fishy smell is detected, it is judged as "having odor". Otherwise, it is judged as "having no odor". (4) High temperature washing test: various samples are washed at different temperatures for 30 minutes with a neutral detergent containing 1 gram / liter and a ratio of 1:50 between fabric and detergent solution. The samples are centrifuged and dried. The number of washes is 30 times. The washing temperatures are 30-40℃, 50-60℃ and 90-95℃ respectively. The antistatic test is carried out on each group of samples after washing. The antistatic effect of each group of samples is rated. The rating results are represented by A, B, C and D respectively. The antistatic strength decreases from A, B, C and D in turn. The final data are as follows:

[0079]

[0080] Based on the above experimental data, the following conclusions are drawn:

[0081] As can be seen from the above table, the various performances of the down jackets produced and processed by the down locking treatment method of the present invention are significantly improved, the number of down roots is ≤10, the softness reaches level 4 or above, and the produced down jackets have no odor, and the produced down jackets have lasting anti-mildew performance during long-term use. By comparing Example 5 with Comparative Example 1, it can be seen that the napping treatment of the fabric can effectively reduce the anti-down drilling ability of the down jacket, and the napping has a certain improvement effect on the softness of the down fabric, avoiding the antistatic agent from spraying to the outside of the fabric through the pores in the fabric when the filling port 4 is sprayed with an antistatic coating when the fabric is in a bulging state, thereby avoiding the antistatic agent affecting the softness of the outer layer of the fabric, and the antistatic agent sprayed on the fabric is added with an aromatherapy agent. It can be seen from Example 5 and Comparative Example 2 that the tamarind fermentation product added to the aromatherapy agent can protect the antistatic performance of the high-temperature water-washed fabric, thereby ensuring the antistatic performance of the high-temperature water-washed fabric.
