Description

Linen-like slub yarn

Technical Field

The utility model relates to a weaving yarn manufacturing and designing field specifically indicates an imitative numb slub yarn.

Background

The production of slub yarn originated in the 70 th 20 th century, and since the advent, it has attracted the attention of the world due to the special texture effect of its fabric. In recent years, the fabric is widely applied to clothes and decorative textiles, and when the slub yarn is used for weaving, protrusions which are uniformly distributed and similar to slubs are formed on the surface of the fabric, so that a special texture can be formed on the surface of the fabric, and a special fabric style is generated.

The flax fiber can be used for clothes fabrics and decorative fabrics, has outstanding patterns, unique style and strong stereoscopic impression, meets the requirements of people on the diversified styles of the fabrics, but has the characteristics of poor elasticity, poor wrinkle resistance and wear resistance, itching feeling and the like, so that the development of the varieties of the flax fiber is always limited, and the slub yarn product has the characteristics of good air permeability, rough hand feeling, unique fancy effect, natural unevenness simulation and the like, has high similarity with the natural flax fiber fabrics, and is a better choice for linen-like fabrics.

Therefore, the patent provides a linen-like slub yarn, various yarns are twisted together through a special process to obtain the slub yarn with a better linen-like effect, besides the linen-like effect, a fabric made of the slub yarn also has the characteristics of heat preservation, comfort, good drapability, toughness, stiffness, pull and the like, and is suitable for weaving the cloth of linen-like overcoat, and the woven product has the vicious hand feeling of the linen fabric returning to nature and the air-permeable and sweat-absorbing performance of cotton fabric, so that the linen-like slub yarn is popular in the market.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides an imitative numb slub yarn twists into core yarn with the low stretch yarn of partly having light through special technology with DTY slub silk to at the core yarn outer covering DTY moth silk with network yarn in advance, obtained one kind and had that the warmth retention is strong, the drapability is good, imitative numb slub yarn that natural numb sense is strong, provides an excellent scheme for imitative numb class yarn.

To the above problem, the utility model provides a following technical scheme:

the core yarn is composed of DTY bunchy yarns and semi-bright low-elasticity yarns, the core yarn forms bamboo sections and flat sections, the core yarn is externally coated with DTY moth-eating yarns and pre-network yarns, the DTY moth-eating yarns and the pre-network yarns are wound in gaps to form a thick yarn section and a thin yarn section, and the warp length ratio of the thick yarn section to the thin yarn section is 1: (1.8-2.2), the weft width ratio is 1: (1.4-1.6), the roving section and the spun yarn section are sequentially arranged at intervals according to the roving section, the spun yarn section, the roving section and the spun yarn section to form a cycle.

Furthermore, the linear density of the DTY slub yarn is 150-180dtex, and the DTY slub yarn is woven by colored terylene.

Furthermore, the semi-bright low stretch yarn is woven by semi-bright POY protofilaments.

Furthermore, the DTY moth silk is woven by semi-dull cationic fibers.

Furthermore, the pre-interlaced yarn is woven by superfine denier profiled cross section POY protofilaments.

Advantageous effects

Firstly, the utility model well solves the problem that the slub yarn is easy to break in the spinning process by the core yarn obtained by twisting the DTY slub yarn and the semi-bright low-elasticity yarn;

secondly, the pre-interlaced yarns are coated outside the core yarns, so that the fabric has good heat insulation performance;

third, the utility model discloses an outer covering DTY moth worm yarn at the core yarn, make the fabric have the natural numb sense of emulation and good drapability, the fabric is three-dimensional tall and straight.
