Technical Field

The invention relates to the technical field of garment processing, in particular to a manufacturing process of a velvet sweater.

Background

The untwisted composite spinning is a brand new spinning process, and the yarn is formed by key technologies such as fiber layering, bonding and the like, so that the untwisted spinning theory proposed in the last century abroad becomes practical. The technology can realize the recombination of the prior textile fiber, realize the free twist spinning from zero twist to normal twist, and establish an integrated textile design system. The invention discloses a non-twisted composite yarn and a process technology thereof in an invention patent with an authorization publication number of CN1181233C, wherein the non-twisted composite yarn is a yarn formed by compounding skeleton yarns (or filaments) and non-twisted short fiber bundles in parallel, and the fabric has a unique single-fiber and single-yarn composite structure. The twistless composite yarn can be processed by a twistless composite spinning machine or a parallel spinning machine, and the two technological methods are superior to the twistless composite yarn. The textile fabric processed by the untwisted composite yarns has better filling power, and has better aesthetic property, comfort and practicability compared with the traditional process.

Velour is a generic name for cut pile velour. The surface is provided with fluff, and most of the fluff is formed by cutting off special warp yarns. The fluff is parallel and neat, so the velvet presents the luster peculiar to the velvet. Such as raised pile, georgette pile, etc. It is used for clothes and decoration. Velour has the following advantages: firstly, velvet has excellent biocompatibility with human bodies, and the surface is smooth, so that the friction stimulation coefficient of velvet to human bodies is second to that of silk; the velvet has excellent wrinkle resistance, elasticity, dimensional stability, good insulating property and extremely wide application, and is suitable for the clothing of all ages and both sexes; and thirdly, the velvet has the characteristics of sun shading, light transmission, ventilation, heat insulation, ultraviolet resistance, fire prevention, moisture prevention, easy cleaning and the like.

However, the velvet processed by the existing velvet textile technology has low fluffy degree, so that the velvet clothes have poor moisture absorption and air permeability. In order to solve the problems, the manufacturing process of the velvet sweater is improved by combining the existing twistless composite spinning manufacturing process.

Disclosure of Invention

The invention aims to provide a manufacturing process of a velvet sweater, which enables the velvet sweater to have better moisture absorption and air permeability.

The above object of the present invention is achieved by the following technical solutions:

a manufacturing process of a velvet sweater comprises the following processing steps:

s1: preparing velvet blended roving;

s2: preparing polyester filament yarns;

s3: processing without twisting, namely spinning the velvet blended roving in the step S1 and the polyester filament yarn in the step S2 into 56 metric count multiplied by 2 composite yarn by using a non-twist textile technology;

s4: z twisting, namely Z twisting is carried out on the 56 metric count multiplied by 2 untwisted composite yarn in the step S3, and the twist degree is set at 360-480 twists/m;

s5, doubling, namely merging 1Z-twisted 56 metric count multiplied by 2 untwisted composite yarn in the step S4 into 1 polyester filament yarn in the step S2;

s6: s twisting, namely S twisting is carried out on the combined 56 metric count multiplied by 2 untwisted composite yarn and the polyester filament yarn in the step S5, and the twist is set at 200 plus 260 twist/m;

s7: and (4) preparing ready-made clothes, weaving the S-twisted combined composite yarn in the step S6 into garment pieces, preparing ready-made clothes and finishing.

By adopting the technical scheme, the velvet blended roving and the polyester filament yarn are spun into the untwisted composite yarn through the untwisted spinning technology, due to the unique characteristic of the structure of the untwisted composite yarn, after the textile fabric is subjected to dyeing and finishing treatment, short fiber bundles in the fabric can form a free loose single fiber state, and the skeleton yarn (or filament) still keeps a single yarn state, so that the fabric has a unique single fiber and single yarn composite tissue structure, and due to the formation of the composite tissue structure, the fabric has better filling power, and the clothes made of the fabric have better moisture absorption and air permeability; the polyester filament has the advantages of high strength, high elasticity, good wear resistance and the like, and the prepared fabric has the advantages of the polyester filament; after Z twisting is carried out on 56 metric count multiplied by 2 untwisted composite yarn, polyester filaments are combined, then S twisting is carried out, and the front twisting direction and the rear twisting direction are opposite, so that the yarn balance is kept.

The invention is further configured to: step S7 specifically includes the following processing steps:

s71: rough processing, namely knitting the S-twisted combined yarns in the step S6 into garment pieces through textile equipment;

s72: finishing, namely sewing the cut pieces obtained in the step S71 to form a velvet sweater;

s73: and finishing, namely finishing the velvet sweater by using a finishing process.

The invention is further configured to: the velour blended roving of step S1 is made by a conventional semi-worsted process.

The invention is further configured to: in step S2, the polyester filament is dyed through a color spinning process.

The invention is further configured to: in step S3, a 56 metric count × 2 twistless composite yarn is made from the velour blended roving and the polyester filament yarn by a twistless composite spinning machine.

The invention is further configured to: the textile apparatus used in step S71 is a 16-needle/hour flat knitting machine.

The invention is further configured to: the velvet sweater finishing process of the step S73 comprises the following steps: washing with water → softening → dehydrating → drying → ironing → inspecting finished product.

By adopting the technical scheme, the velvet sweater is washed, softened, dehydrated, dried and ironed, so that the velvet sweater is decontaminated, unhaired, increased in softness, wrinkle-removed and shaped; the finished product inspection can be used for inspecting whether the ready-made clothes meet the delivery standards.

In conclusion, the beneficial technical effects of the invention are as follows:

1. in the technical scheme, the velour blended roving and the polyester filament are spun into the untwisted composite yarn through the untwisted spinning technology, due to the unique characteristic of the structure of the untwisted composite yarn, after the textile fabric is dyed and finished, short fiber bundles in the fabric can form a free and loose single fiber state, and the skeleton yarn (or the filament) still keeps a single yarn state, so that the fabric has a unique single fiber and single yarn composite organization structure;

2. washing, softening, dehydrating, drying and ironing the velvet sweater so as to remove dirt, hair, increase softness, remove wrinkles and shape; the finished product inspection can be used for inspecting whether the ready-made clothes meet the delivery standards.
