Problems solved by technology

[0004] In recent years, the types of stockings at home and abroad are mainly divided into two categories. One is stockings woven with two-way covered yarn and two-way nylon. Permeability and clarity, uniform texture, so it is also called silk stockings, but the feel and softness of this kind of stockings are not enough; one type is four-way silk stockings woven entirely of covered yarn, which is called four-way silk stockings in the industry, four-way silk stockings Covered yarn is soft to the touch, so it is also used as velvet stockings, but this type of stockings has the problem of poor permeability and uneven wearing

Embodiment 1

[0047] 1. Raw material matching

[0048] Raw material matching is a very important step in the present invention. After many tests, the present invention selects two lines of spandex yarns with a fineness of 20D-70D, which is called the first group. In this embodiment, the conventional fineness of 20D is taken as an example. The fineness of the other two lines of spandex yarns is 10D-15D, which is called the second group. In this embodiment, the fineness of 10D is taken as an example. Nylon yarn for outsourcing can choose the same fineness, generally 5D-12D, or the nylon yarn of the first group can be slightly thicker than that of the second group. Considering the situation of reducing snags during hosiery knitting and wearing, if the second group adopts the low-twist processing method, the nylon yarn of the second group should choose nylon yarn with the same fineness and low number of holes. The present invention takes FDY 10D / 5F nylon yarn as an example, if the second group...

Embodiment 2

[0069] A production process for weaving uniform and transparent four-way silk stocking covering yarn, comprising the following steps:

[0070] 1) Raw material matching: the first group uses 20D ordinary spandex yarn as the core, and covers it with FDY 8D / 5F nylon yarn, that is, the specification of the covering yarn is 2008 / 5; the second group uses 10D ordinary spandex yarn as the core, and uses The nylon yarn of FDY8D / 5F is covered, that is, the specification of the covered yarn is 1008 / 5;

[0071] 2) Winding: Winding is carried out according to the conventional process;

[0072] 3) Drafting: the drafting ratio of the first group of covered yarns 2008 / 5 is set to 3.4, and the drafting ratio of the second group of 1008 / 5 is set to 2.2;

[0073] 4) Twisting: the twists of the two sets of covered yarns are all set to 1800;

[0074] 5) Winding: Winding is carried out according to the conventional process, and the winding rate is set to 90%;

[0075] 6) Knitting and shaping: pu...

Embodiment 3

[0077] A production process for weaving uniform and transparent four-way silk stocking covering yarn, comprising the following steps:

[0078] 1) Raw material matching: the first group uses 20D anti-stripping spandex yarn as the core, and covers it with FDY 12D / 24F nylon yarn, that is, the specification of the covering yarn is 2012 / 24; the second group uses 10D anti-stripping spandex yarn as the core , covered with FDY12D / 24F nylon yarn, and the specification of covered yarn is 1012 / 24.

[0079] 2) Winding: winding according to the conventional process

[0080]3) Drafting: the draft ratio of the first group of covered yarns 2012 / 24 is set to 3.4, and the draft ratio of the second group of 1012 / 24 is set to 2.2

[0081] 4) Twisting: the twist of the two sets of covered yarns is set to 1700

[0082] 5) Winding: Winding is carried out according to the conventional process, and the winding rate is set to 90%

[0083] 6) Knitting and shaping: Put two groups of covered yarns in a...

Abstract

The invention discloses a production technology of uniformly-knitted transparent four-way silk stocking wrapping yarn. Silk stockings are matched with wrapping yarn of two different raw materials and technologies. The silk stocking manufacturing technology sequentially comprises raw material matching, spooling, drafting, twisting, winding, knitting and forming. According to the raw material matching step, the method for matching spandex of different thicknesses, the uniformity of silk stockings can be improved, and the silk stocking clarity can be improved; according to the drafting step, thick spandex high drafting and thin spandex low drafting are matched to be adopted as raw materials, the high and low strength matching of the two materials is obvious due to the matching of the two technologies, and the knitted silk stockings can achieve the best effect.

Description

technical field [0001] The invention relates to a production process of covered yarn Background technique [0002] As a daily consumer product, stockings are increasingly appearing in people's lives, such as some formal business occasions, attending events, and daily work and life. People's requirements for stockings are also constantly improving, and they have different demands for appearance and wearing aesthetics, as well as some functions. [0003] The covered yarns used to make stockings are all nylon covered yarns, that is, the nylon yarns are evenly covered outside the spandex yarns according to the set twist. The covered yarns are usually expressed in the industry as: 2008 / 5; 20 is the D of spandex The number indicates the 20D spandex yarn used; 08 is the D number of nylon, indicating 8D nylon yarn, and / 5 is the number of holes in nylon yarn, indicating that 8D nylon yarn has 5 holes. Other specifications and so on. [0004] In recent years, the types of stocking...
