Definitions

• This invention relates to agents for sizing tex tile fibers and process of preparing them. r
• the loose ends which project from a. textile thread canbe smoothly laid on the surface of the thread by treating the threads with sizing agents.
• sizing agents there are principally used starch (either alone or mixed with fat, wax or parafiin and the like), dextrin, glue or similar substances.
• starch either alone or mixed with fat, wax or parafiin and the like
• dextrin glue or similar substances.
• the textiles sized according to the processe hitherto known in most cases can be freed from size only by special operations; Thus, for in-y stance. the sizes containing starch must be treated with a ferment decomposing-starch or with an Y oxidizing agent or a substance of hydrolytic ac- .tion.
• the sizing agent which .is suitable for cotton cannot beapplied with the same good effect to other textile fibers. 1
• an excellently well sized material is'obtained by treating textile fibers with compounds of'high molecular weight of the type of polyvinyl alcohol.
• the size is absorbed by the fiber already after a short treatment and may be appliedequally well to'varlous textile fab-' rics; in each case there is obtained a perfectly well sized thread.
• the alcohol may be applied at temperatures of 10 CF90? C. v
• polyvinyl alcohols there may be used products of various lengths of chain and various chem- I ical constitution obtained by any of the usual methods. Processes of preparingthem are, for instance, described in Berichte .der Deutschen Chemischenmaschine, 19 27, pages 1658-1663. According to the desired effect of the products theymay also be prepared from polyvinyl este of various degrees of viscosity.
• the polyvinyl alcohol may be applied either invention but are not intended to limit it thereto, the parts beingby weight: a
• a sizing such as oil, fat wax or the like.
• additional material used for a sizing such as oil, fat wax or the like.
• the thread remains very pliable ifa sulfonated oil is added to the sizing bath.
• the material sized and dried according to the present process is free from dust, whereas this is generally not the case with material prepared with resin containing starch.
• the material can very well easily be"freed from the size, for instance by simply rinsing it in hot water, to which may be added a small'quantity of f soap, without applying any other auxiliary means.
• Material which is not at all or not entirely freed from the size can be dyed without any difli- .culty since the sizeand the fibrous material used are dyed equally.
• Cotton yarn is passed through a bath in which polyvinyl alcohol is dissolved in the pro- 15.
• the yam sized according-to (a) or (b) is introduced into a dyebath at about 45 C. without previousv washing and the bath is slowly heated to 20 80 C. The material is then dyed with the usual additions, rinsed and dried.
• the yam sized according to(a) or (b) is dyed by introducing it at about 40 C. into a dyebath and raising the temperature slowly to 60 C. it is dyed with the usual admixtures and then rinsed and dried;
• the yarn sized according to (a) or (b) is inout being washed previously and heated slowly to 80 C. It is dyed with the usual admixtures, then rinsed and dried.
• a process of sizing textile fibers which comprises treating the fiber with a solution of a polyvinyl alcohol. i i
• An agent for sizing textile fibers which comprises a polyvinyl alcohol and a sulfonated oil.
• a process of sizing textile fibers which comprises treating the fiber with a sizing composition comprising a' polyvinyl alcohol and material of the group consisting of oils, fats and waxes.
• a textile sizing composition comprising a polyvinyl alcohol and a material of the group consisting of oils, fats and waxes.
• a solution of a polyvinyl alcohol As a sizing agent for textile fibers, a solution of a polyvinyl alcohol.
• a process of sizing textile fibers which comprises treating the fiber with a textile sizing composition comprising an efiective amount of a polyvinyl alcohol.
• a textile sizing composition comprising an effective amount of a polyvinyl alcohol.
