Description
Technical field
The present invention relates to the manufacture crafts of clothes, and in particular to a kind of down jackets preparation process.
Background technology
With the improvement of living standards, requirement of the people to dress is also higher and higher, in addition to needing to meet substantially warming
It is required that outer, desirably promote aesthetic feeling by the dress of itself, show individual character, for women, need purchase,
Prepare different types of clothes to participate in different activities, attend different occasions.Since the temperature in winter is relatively low, down jackets are
The necessity that everybody passes the winter.But the manufacturing process of down jackets but actually bothers, since it is desired that natural feather is filled in down jackets
It is interior, but filling process is once uneven, the uneven of natural feather in down jackets is will result in, whole warmth retention property is leveraged
Energy and performance attractive in appearance.
Invention content
It is in view of the drawbacks of the prior art and insufficient, it is easy to make the purpose of the present invention is to provide a kind of simple for process
Down jackets preparation process.
To achieve the above object, the technical solution adopted by the present invention is：A kind of down jackets preparation process, innovative point exist
In：By cutting, making, the preparation of feather sphere, the filling of feather sphere and sewing step, the preparation of down jackets is completed；Specific step
It is rapid as follows：
（1）It cuts：Lining and fabric are cut out into standard by version, are cut into：Anter, rear piece, coat-sleeve, collar, cap, pocket；
（2）It makes：According to drawing and sample arrangement circuit, needle gage：11-13 needles/3cm open-wire line marks, 12-14 needles/3cm concealed wire marks；
Joint close 11# eedles, lead 9# eedles use the colo(u)r streak with fabric with colour system；Each position circuit wants straight, sewing thread trace
Must not there are single-hop and continuous bouncing pilotage at two, over-lock stitch not to allow bouncing pilotage in 30cm, it is elastic suitable that face, baseline are answered, and rising and falling will
Return needle；
（3）The preparation of feather sphere：It is wrapped up in by the pre-treatment of natural feather, the compression of natural feather, the preparation of water-soluble binder, natural feather
Attached, feather sphere sizing and baking step, complete the preparation of feather sphere；
（4）The filling of feather sphere：The feather sphere being prepared uniformly is packed in interlayer according to number；
（5）Sewing：Then interlayer sewing is got up, that is, completes the preparation of down jackets.
Further, the step（3）It is as follows：
A. the pre-treatment of natural feather：Natural feather is cleaned, the natural feather after cleaning is placed in buck and is impregnated, heats boiling,
Then it air-dries for use；
B. the compression of natural feather：Natural feather after air-drying is placed in the compression groove that feather sphere is prepared in dedicated unit, cylinder is passed through
The compression of natural feather is carried out, is then discharged by exporting a；
C. the preparation of water-soluble binder：By polyacrylamide, formaldehyde, neck dibatyl phithalate, poly- diethanol, polyvinyl alcohol
Formal, high energy refined fish oil, hydrochloric acid and deionized water are prepared, specific mass percent be polyacrylamide 7%-15%,
Formaldehyde 10%-30%, neck dibatyl phithalate 2%-10%, poly- diethanol 8%-15%, polyvinyl formal 6%-20%, high energy essence
Refine fish oil 2%-5%, hydrochloric acid 1%-5% and deionized water 15%-30%；
D. natural feather wrap up in it is attached：It by natural feather by the package of water-soluble binder, is moved downward by channel, then passes through cutter
Tool is cut；
E. the sizing of feather sphere：Feather sphere after the completion of cutting is passed through fixed slot by the brushing water-soluble binder on fixed slot
Sizing treatment so that feather sphere is more complete round and smooth, and the water-soluble binder on fixed slot can complete cutting tool
Cut surface it is compound；
F. it dries：The feather sphere in fixed slot is subjected to drying and processing by drying pipe, is then taken feather sphere by exporting b
Go out, completes the preparation of feather sphere.
Further, the step（a）In the alkaline soak time be 60-66h, the boiling temperature be 120-140 DEG C.
The present invention has the beneficial effect that：The present invention prepares dedicated unit by using feather sphere, can be done directly feather sphere
Preparation, preparation method is simple, filling natural feather it is more convenient so that the preparation of whole down jackets is more convenient, and down-filling imitate
Fruit is more uniformly distributed.
